County ADU ordinance

Pittsylvania County regulates accessory dwelling units through its county Zoning Ordinance, administered by the Pittsylvania County Department of Community Development (Planning and Zoning) under the authority of the Pittsylvania County Board of Supervisors. Virginia is a Dillon Rule state and the General Assembly has not enacted any statewide ADU preemption; Pittsylvania County's authority to regulate or prohibit ADUs derives solely from the general zoning enabling statute at Va. Code § 15.2-2280 and the ordinance-content provisions of § 15.2-2286. Pittsylvania County is the second-largest Virginia county by land area (approximately 969 square miles) and a predominantly rural Southside Virginia county with population approximately 60,000, located on the North Carolina border (abutting Rockingham and Caswell counties in NC), with the independent City of Danville as a donut hole in the south-central portion of the county (Danville is a Virginia-unique independent city governed entirely separately, not a municipal subdivision of the county — see Va. Const. Art. VII § 1 and Va. Code § 15.2-3200 et seq.). The county seat is the Town of Chatham, an incorporated town near the geographic center of the county along US 29. Pittsylvania County's historical economy was centered on bright-leaf tobacco cultivation (the county was for much of the 19th and 20th centuries one of the nation's leading flue-cured tobacco producers), textile and furniture manufacturing in the Danville-adjacent corridors, and timber; the modern economy has pivoted sharply toward large-scale data center development in the Gretna / Berry Hill / Southern Virginia Mega Site corridor, along with agricultural, timber, and the emerging solar-farm utility-scale renewable development. Major Pittsylvania County land-use attention in recent years has centered on the Southern Virginia Mega Site at Berry Hill (a multi-thousand-acre industrial park straddling the Virginia / North Carolina border southwest of Danville), Balico / data-center entitlements in the Gretna area, and large utility-scale solar applications that have triggered Board of Supervisors ordinance amendments and SUP tracking. The county's zoning ordinance establishes conventional Virginia use districts (Agricultural A-1, Residential Suburban Subdivision R-1, Residential Estate RE, Business B-1 / B-2, Industrial M-1 / M-2, and applicable overlays including floodplain, manufactured-housing, and airport-safety overlays) and specifies permitted, accessory, and special-use lists for each district. A second dwelling on a single residential parcel is not universally a by-right permitted use in standard residential districts; ADU-style projects in the unincorporated county typically proceed through (a) the county's family-member dwelling / family-subdivision provisions (limited to immediate-family occupancy), (b) a discretionary Special Use Permit approved by the Board of Supervisors following Planning Commission recommendation under Va. Code §§ 15.2-2285, 15.2-2286, or (c) a minor subdivision placing the second dwelling on its own lot. Pittsylvania County has not adopted a standalone ministerial ADU ordinance of the California / Oregon / Washington type; the practical effect is that a homeowner cannot rely on an ADU-by-right framework for non-family rental occupancy, and each such project is subject to district-specific analysis and generally a discretionary Special Use Permit process.

State-floor overlay: Virginia has not enacted any statewide ADU preemption statute. Virginia is a Dillon Rule state (see Commonwealth v. County Bd. of Arlington County, 217 Va. 558 (1977)); localities have only those powers expressly granted by the General Assembly. The general zoning enabling statute at Va. Code § 15.2-2280 grants counties, cities, and towns broad authority to regulate land use, and § 15.2-2286 enumerates the specific ordinance provisions that may be included. Neither statute, nor any section of Title 15.2 Chapter 22 Article 7, mandates that a locality permit ADUs, requires ministerial review of ADU applications, caps parking requirements, caps fees, or voids owner-occupancy requirements. Pittsylvania County is therefore free to permit, restrict, or prohibit second dwellings under its zoning ordinance within the ordinary constitutional limits on land-use regulation. ADU preemption bills have been introduced in the Virginia General Assembly in multiple recent sessions (2022-2025) without enactment; the statewide regulatory picture at the county level is unchanged as of 2026-04-21.

County permitting (unincorporated parcels)

The Pittsylvania County Department of Community Development (Planning and Zoning, together with Building Inspections) is the sole permitting authority for building permits, zoning permits, and Special Use Permits on parcels within the unincorporated county (i.e., parcels outside the corporate limits of the City of Danville — a fully independent city, not a subdivision of the county — and outside the three incorporated towns of Chatham, Gretna, and Hurt). Pittsylvania County comprises approximately 969 square miles, making it the second-largest Virginia county by land area (behind Augusta County), predominantly rural Southside Virginia territory bounded to the south by the North Carolina state line (Rockingham and Caswell counties in NC), to the east by Halifax County, to the north by Campbell County and Bedford County (briefly), and to the west by Franklin County and Henry County; the independent City of Danville sits as a donut hole in the south-central portion of the county. Major population concentrations outside Danville are in the Chatham area (county seat, along US 29 near the geographic center of the county), the Gretna area (along US 29 in the north, the focal point of recent data-center and industrial-development interest), the Hurt / Altavista-adjacent corridor (along the Staunton River / Roanoke River in the far north, straddling the Pittsylvania / Campbell county line), the Blairs / Ringgold / Dry Fork corridor (along US 58 east of Danville), and the western communities of Cascade, Callands, and the Berry Hill area (site of the Southern Virginia Mega Site). The vast remainder of the county is rural agricultural (historically tobacco, now pivoting to row crops, cattle, timber, and utility-scale solar), timber, and scattered residential parcels administered by the county. For an ADU-style project in the unincorporated county, the typical sequence is: (a) zoning determination by the zoning administrator (permitted by right under a narrow family/kinship reading, permitted via Special Use Permit, or prohibited); (b) if SUP required, application to the Planning Commission and Board of Supervisors under Va. Code §§ 15.2-2204, 15.2-2285, 15.2-2286; (c) building permit application to the county building official; (d) Virginia Department of Health Pittsylvania-Danville Health District approval for well/septic where parcels are not served by public utilities; (e) VDOT entrance permit if a new or altered driveway enters a state-maintained road; (f) inspections through construction; (g) certificate of occupancy. Applicants should expect a substantially longer timeline than a first-dwelling build when an SUP is required, because the SUP process is a public-hearing process with statutory notice requirements (two successive weeks' advertisement and five-day final-notice under Va. Code § 15.2-2204).

Process overview: Pittsylvania County's ADU-style permitting process varies by project pathway: (1) Family-member dwelling / family subdivision — if the second dwelling is for an immediate family member of the primary-dwelling owner and qualifies under the county's family-dwelling or family-subdivision provisions, the zoning administrator may issue an administrative zoning approval followed by a standard building permit; this is the fastest path when eligible, typically 4-8 weeks end-to-end assuming no building-code or well/septic complications. (2) Special Use Permit for a rental or non-family second dwelling — the applicant submits a completed SUP application with site plan, statement of use, and the required filing fee to the Community Development Department. Staff conducts a zoning analysis and prepares a staff report. The Planning Commission holds a public hearing (advertised per Va. Code § 15.2-2204: once a week for two successive weeks, with final notice not less than five days before the hearing) and makes a recommendation. The Board of Supervisors then holds its own public hearing and votes. The entire SUP process typically takes 60-120 days from complete submission to Board decision; complex applications or those requiring ordinance interpretation can take longer. (3) Minor subdivision — if the applicant prefers to create a separate buildable lot and construct a fully separate dwelling, the subdivision ordinance (separate chapter of the county code) applies. Subdivision review runs through the subdivision agent and the Planning Commission; timelines vary from approximately 30 days (simple minor subdivision) to 6+ months (major subdivision requiring road approval, stormwater management, and VDOT entrance approval). Building permits for a second dwelling require compliance with the Virginia Uniform Statewide Building Code (USBC), the single statewide building code for Virginia localities; localities cannot adopt more stringent building-code amendments (Va. Code § 36-98). Well and septic approval (for unincorporated parcels not served by public utilities) is administered by the Virginia Department of Health Pittsylvania-Danville Health District and is required before a building permit can be issued for a dwelling not connected to public water/sewer. Entrance-permit approval by the Virginia Department of Transportation (VDOT) Lynchburg District (covering Pittsylvania County) may be required where the new dwelling uses a new or altered driveway onto a state-maintained secondary road. Additional approvals may apply for parcels in the Danville Regional Airport safety overlay (just north of Danville in the Blairs area), FEMA Special Flood Hazard Areas along the Dan River, Staunton River, or Smith River corridors, and any parcel within the Agricultural and Forestal Districts (AFD) where ADU compatibility must be confirmed with the AFD advisory committee.

Impact fees: Virginia localities generally do not levy impact fees of the type used in California or Florida; Virginia Code does not broadly authorize impact fees for counties outside certain narrowly enumerated categories (road impact fees under Va. Code § 15.2-2317 through § 15.2-2327 are available only to counties meeting specific growth-rate and density criteria, which Pittsylvania — a large, rural, population-stable-to-declining Southside county — does not meet). Pittsylvania County does not appear on the list of counties that have adopted a road-impact-fee ordinance under that authority as of 2026-04-21. Cash proffers tied to rezoning applications were formerly common in fast-growth Virginia jurisdictions but are now constrained by Va. Code § 15.2-2303.4 (2016), which limits residential proffers. For an ADU built on an existing parcel without rezoning, the applicant pays building-permit fees (set by the county by ordinance and keyed to project valuation), any SUP application fee if applicable, connection or tap fees for water/sewer (if served by a public utility — applicable in limited service areas operated by the Pittsylvania County Service Authority or by individual town utility systems in Chatham, Gretna, and Hurt; generally not applicable in the deep rural county), and state and local permit surcharges. Applicants should request a current fee schedule from the Community Development Department at application time. (schedule)

County assessor

Pittsylvania County real property is assessed by the Pittsylvania County Commissioner of the Revenue's Real Estate division (and, during reassessment cycles, by contracted mass-appraisal vendors working under the direction of the Commissioner and the Board of Supervisors); tax bills are collected by the Pittsylvania County Treasurer. Virginia law requires general reassessment of real property at least once every four years for most counties (Va. Code § 58.1-3252), with more frequent cycles permitted; Pittsylvania County historically conducts a general reassessment on a multi-year cycle set by the Board of Supervisors and has generally contracted with a mass-appraisal vendor for cycle execution. Unlike California's Proposition 13 acquisition-value system, Virginia uses a fair-market-value assessment system: a parcel is assessed at 100% of fair market value as of the effective date of the reassessment, and that value stands until the next general reassessment (subject to supplemental assessment for new construction). When an ADU / accessory dwelling is added to an existing parcel, the new structure is added to the assessment roll at its contributory fair market value; the primary dwelling's assessed value is not automatically re-triggered by the ADU construction itself, but the parcel's overall assessed value rises by the ADU's contributory value. At the next general reassessment, both structures are re-valued at current fair market value together. The property-tax bill equals assessed value times the Board of Supervisors' adopted real-estate tax rate (set annually in the county budget process); Pittsylvania County's real-estate tax rate has historically sat in the moderate-to-low range among Virginia counties, reflecting the county's large rural base and the fiscal pressures of a Southside county with stable-to-declining population. Pittsylvania County participates in Virginia's use-value taxation program under Va. Code § 58.1-3230 et seq. for qualifying agricultural, horticultural, and forestal land — a substantial benefit for the very large share of the county's acreage in tobacco-legacy farmland, pasture, row crops, and commercial timber. Note that real property inside the City of Danville is assessed by the City of Danville's own assessor, NOT by the Pittsylvania County Commissioner of the Revenue, because Danville is an independent city; applicants holding property inside Danville corporate limits deal with the city, not the county. Parcels inside the towns of Chatham, Gretna, or Hurt are still assessed by the county (because towns, unlike independent cities, are not constitutionally separate), but those towns levy their own town-level real-estate tax on top of the county's rate.

Assessment policy: Virginia is a fair-market-value assessment state; a new ADU is added to the assessment roll at its contributory fair market value as a supplemental assessment effective from completion (building permit final inspection or certificate of occupancy) through the balance of the tax year. The primary dwelling's prior assessed value is not automatically reset by the addition of the ADU, but the parcel's total assessed value increases by the ADU's contributory value. At the next general reassessment (Pittsylvania County operates on a multi-year reassessment cycle set by the Board of Supervisors), both the primary dwelling and the ADU are re-valued at current fair market value. Owners electing to convert existing interior space (e.g., a basement apartment or detached-garage conversion) to a permitted ADU should expect the contributory value to reflect the creation of a second kitchen and second entry and the resulting increase in market-rent potential of the parcel; an owner adding a detached ADU typically sees a larger incremental assessment increase than one converting existing interior space. Property-tax rates are set annually by the Pittsylvania County Board of Supervisors in the county budget process; owners should confirm the current year's rate from the county's adopted budget because rates change annually. The recent wave of large-scale industrial and data-center assessments in the Gretna and Berry Hill corridors has materially grown the county's non-residential tax base and may affect the trajectory of the residential rate in future budget cycles.

County overlays (8)

Pittsylvania County administers or is subject to several overlay regimes that affect ADU siting on unincorporated parcels: (1) FEMA Special Flood Hazard Areas along the Dan River (the county's dominant southern waterway, flowing west-to-east through Danville and then into North Carolina), the Staunton River / Roanoke River on the county's northern boundary with Campbell and Halifax counties, the Banister River (which bisects the county northwest-to-southeast and runs through Chatham), the Pigg River in the northwestern portion of the county (Gretna area), and scattered smaller-stream SFHAs across the county — administered through the county's floodplain overlay ordinance satisfying NFIP minimums; (2) Danville Regional Airport safety overlay — Danville Regional Airport (IATA: DAN) sits in the Blairs area of Pittsylvania County (in the county, not inside Danville city limits, despite the name — the airport is owned by the City of Danville but located on county land), and the FAR Part 77 imaginary surfaces and Virginia airport-safety overlay criteria impose height limitations, use restrictions, and avigation-easement recommendations on parcels in the approach and transitional surfaces around the airport; (3) Agricultural and Forestal Districts established under Va. Code § 15.2-4300 et seq. are extensively present throughout the county, reflecting its dominant agricultural and timber land use, providing participating landowners use-value taxation and subdivision-deferral protections in exchange for a commitment to keep land in agricultural or forestal use; (4) the Chesapeake Bay Preservation Act does NOT apply — Pittsylvania County is not in the Tidewater area covered by Va. Code § 62.1-44.15:67 et seq., so Resource Protection Areas (RPAs) and Resource Management Areas (RMAs) do not apply (Pittsylvania drains to the Albemarle Sound via the Dan/Roanoke river system, outside the Chesapeake Bay watershed per the Act's Tidewater definition); (5) wildfire risk is tracked by the Virginia Department of Forestry, but Virginia does not have a California-style Very High Fire Hazard Severity Zone regulatory overlay mandating ignition-resistant construction — the Virginia Uniform Statewide Building Code does not statewide-adopt the International Wildland-Urban Interface Code, and Pittsylvania County has not imposed a local WUI construction overlay; (6) utility-scale solar facility siting overlay — Pittsylvania County has adopted zoning ordinance provisions governing utility-scale solar generating facilities (siting criteria, setbacks, viewshed buffers, decommissioning bond requirements) in response to significant solar-farm application volume on former tobacco acreage, and these provisions are a material feature of the county's current regulatory landscape even though they do not directly govern residential ADUs; (7) data-center and heavy-industrial district provisions in the Gretna / Berry Hill corridor and at the Southern Virginia Mega Site (Berry Hill area on the Virginia / North Carolina border southwest of Danville), which have been the focus of significant recent Board of Supervisors ordinance activity but which do not directly impose residential ADU constraints; (8) Leesville Lake (on the Staunton/Roanoke River along the county's northwestern edge, the downstream reservoir of the Smith Mountain Pumped Storage Project) is a FERC-licensed Appalachian Power (AEP) reservoir with its own shoreline management plan governing docks, structures, and land-use on adjacent parcels — this overlay is distinct from the USACE regime on Philpott Lake (in Henry/Franklin/Patrick counties) and the USACE John H. Kerr Reservoir (straddling Mecklenburg and Halifax counties further east on the Roanoke/Staunton system).

  • FEMA National Flood Insurance Program — Special Flood Hazard Areas — Pittsylvania County participates in the National Flood Insurance Program and administers a county floodplain overlay ordinance meeting NFIP minimums. The principal Special Flood Hazard Area (SFHA) extents in the county are along the Dan River (the dominant southern waterway, flowing west-to-east from the Patrick County line through Danville to the North Carolina state line), the Staunton River / Roanoke River along the county's northern boundary with Campbell and Halifax counties, the Banister River (which bisects the county northwest-to-southeast and runs through Chatham), the Pigg River in the northwestern portion of the county (Gretna / Hurt area, flowing into Leesville Lake), Sandy River, Cherrystone Creek, and scattered SFHAs along smaller streams across the county. An ADU sited in an SFHA must comply with NFIP elevation requirements (lowest finished floor at or above Base Flood Elevation plus any county freeboard), flood vent requirements on enclosed areas below BFE, anchoring requirements, and post-construction Elevation Certificate filing. Owners should confirm current-effective FIRM panel at the FEMA Map Service Center before design; FEMA has periodically updated Virginia county panels. Note that much of the county's river-corridor acreage is historically farmland floodplain (particularly along the Banister and Dan rivers) where SFHA mapping is a significant siting constraint for any non-agricultural structure.
  • Danville Regional Airport safety overlay (FAR Part 77 imaginary surfaces) — Danville Regional Airport (DAN) is located in the Blairs area of Pittsylvania County (despite its name, the airport sits on county land immediately north of the Danville city line; the airport is owned by the City of Danville but located in Pittsylvania County). FAR Part 77 imaginary surfaces — primary surface, approach surface, transitional surface, horizontal surface, and conical surface — extend outward from the runway ends and impose height limitations on structures in the surrounding area. Virginia Code § 15.2-2294 authorizes localities to adopt airport-safety zoning for such airports, and Pittsylvania County's zoning ordinance includes airport-safety overlay provisions around DAN. An ADU sited within the approach or transitional surfaces may be subject to height restrictions, avigation-easement recommendations, and (at some distances) FAA Form 7460-1 notice requirements. Owners of parcels in Blairs, along US 29 immediately north of Danville, and in the approach corridor to the north / south runway ends should consult the zoning administrator and the airport authority early in ADU design to confirm allowable structure height at the specific parcel.
  • Virginia Agricultural and Forestal Districts (local option under state law) — Pittsylvania County has extensive agricultural and forested acreage — given the county's 969-square-mile footprint and dominant tobacco-legacy / row-crop / timber land use, Agricultural and Forestal District enrollments are among the most significant in the Commonwealth. Where AFD enrollment exists, enrollment is voluntary; participating landowners commit to keeping land in agricultural or forestal use for a period (typically 4-10 years) in exchange for use-value assessment (Va. Code § 58.1-3230 et seq.) and limited protection from certain governmental actions that would disrupt agricultural use. An ADU on an AFD-enrolled parcel is generally permitted if it is an accessory use to continued agricultural operation (e.g., a farm-labor dwelling or family dwelling), but non-agricultural commercial-rental ADUs may conflict with AFD purposes and trigger AFD committee review and potentially withdrawal from the district (with rollback-tax consequences on the withdrawn acreage). Owners should consult the Pittsylvania County AFD Advisory Committee (for the applicable district) and the zoning administrator before assuming ADU compatibility. The fiscal cost of withdrawal — up to five years of roll-back taxes on the difference between use value and fair market value — can be substantial on large timbered tracts.
  • Virginia Uniform Statewide Building Code and VDOF wildfire risk (no WUI regulatory overlay) — Pittsylvania County includes substantial wooded terrain (roughly half of the county is forested, including significant commercial pine plantations on former tobacco acreage and natural hardwood stands along the county's river corridors) with moderate wildfire exposure tracked by the Virginia Department of Forestry, but Virginia does not have a statewide Very High Fire Hazard Severity Zone regulatory overlay that mandates WUI-rated construction materials on a per-parcel basis. Under Va. Code § 36-98 the Virginia Uniform Statewide Building Code is the single statewide building code; localities cannot impose more stringent local building-code amendments. Virginia has not statewide-adopted the International Wildland-Urban Interface Code. Owners in wildfire-exposed locations should follow defensible-space best practices and coordinate with VDOF outreach, but face no locality-imposed WUI construction overlay analogous to California Chapter 7A or Oregon WUI code.
  • Utility-scale solar facility siting (zoning ordinance overlay) — Pittsylvania County has adopted zoning ordinance provisions governing utility-scale solar generating facilities in response to a large volume of solar-farm applications on former tobacco acreage. The solar siting provisions establish setback requirements from adjacent residential parcels, vegetative viewshed buffer requirements, decommissioning bond requirements, stormwater / erosion-and-sediment control requirements, and Special Use Permit processes for commercial-scale solar. These provisions are a material feature of the county's current regulatory landscape and periodically consume Planning Commission and Board of Supervisors hearing calendar capacity, which can affect scheduling of residential SUP applications (including ADU SUPs). The provisions do not directly govern residential ADUs, but ADU projects proposed on parcels adjacent to approved or pending utility-scale solar facilities may encounter viewshed, glare, or panel-setback considerations worth confirming at pre-application.
  • Leesville Lake (FERC Smith Mountain Project No. 2210) shoreline management — AEP Appalachian Power — Leesville Lake is the lower (afterbay) reservoir of the Smith Mountain Pumped Storage Project, a FERC-licensed hydroelectric pumped-storage facility operated by Appalachian Power (AEP) on the Staunton/Roanoke River. Leesville Lake straddles Pittsylvania County (northwestern edge — the Hurt / Altavista area in the far north of the county), Campbell County (north shore), and Bedford County (portions of the upstream end). The FERC-approved Shoreline Management Plan governs docks, boathouses, shoreline vegetation, and any structure within the project boundary on parcels adjacent to the lake; AEP (not the county) issues shoreline-use permits for qualifying alterations. A parcel on Leesville Lake shoreline in Pittsylvania County is subject to both county zoning (setbacks, dwelling-count) and AEP / FERC shoreline permitting, and an ADU / second dwelling on such a parcel requires coordination with both authorities. This regime is distinct from the USACE-administered shoreline at Philpott Lake (Henry/Franklin/Patrick counties) and from the USACE John H. Kerr Reservoir (Mecklenburg/Halifax counties).
  • Southern Virginia Mega Site at Berry Hill (industrial-district overlay adjacency) — The Southern Virginia Mega Site at Berry Hill is a multi-thousand-acre industrial park in southwestern Pittsylvania County, straddling the Virginia / North Carolina state line southwest of Danville. The site is zoned and master-planned for large-scale manufacturing and heavy industrial users and is a focal point of Virginia Economic Development Partnership industrial-recruitment activity. The site itself does not impose an overlay on residential ADU siting, but adjacent residential parcels (particularly in the Cascade / Callands corridor and along the NC border) face practical considerations — truck-traffic impacts, industrial noise / lighting spillover, potential air and water quality concerns depending on eventual occupants, and the visual character change from former tobacco farmland to industrial-park uses. ADU projects on parcels adjacent to the Mega Site boundary should factor these considerations into siting, particularly for short-term-rental or long-term-rental ADUs where end-user preferences may be sensitive to heavy-industrial adjacency. Recent Board of Supervisors attention to this area has focused on infrastructure build-out (water, sewer, rail, highway access) rather than on residential zoning, but applicants should confirm current zoning-map status of specific parcels.
  • Data-center district activity in the Gretna corridor — Pittsylvania County has been the focus of significant recent data-center development interest along the US 29 corridor in the Gretna area (northern part of the county), including the Balico and related data-center project sites. The Board of Supervisors has devoted substantial hearing time to rezoning and SUP applications for large-scale data-center developments, which involve substantial electrical-infrastructure build-out (transmission-line rights-of-way, substation siting) and significant water-use considerations. These land-use decisions do not directly govern residential ADU projects, but ADU projects on parcels adjacent to approved or pending data-center sites may be affected by the same electrical-transmission and water-infrastructure changes, and residential applicants in Gretna-area parcels should confirm current parcel zoning and any adjacent approvals at pre-application.

Known county issues (9)

  • policy-review — Homeowners cannot rely on a ministerial ADU-by-right approval path; most rental-ADU projects will require a discretionary Special Use Permit (60-120 day public-hearing process) or a minor subdivision. This adds materially to project timeline, uncertainty, and soft costs relative to states with statewide ADU preemption.
  • other — Applicants must first verify whether their parcel is inside Danville (city ordinance and city permitting govern) or in the surrounding unincorporated county (county ordinance and county permitting govern). The 'donut' geography makes this an unusually frequent source of confusion — many Danville-addressed parcels (using Danville ZIP codes 24540, 24541, etc.) are actually outside Danville's corporate limits and in Pittsylvania County, particularly in the Blairs, Westover, and northern approach corridors. A mistaken assumption can route applicants to the wrong permit counter, with weeks of rework and potentially incorrect ordinance analysis.
  • other — Applicants near any of the three towns must verify whether their parcel is inside town corporate limits (town ordinance governs) or outside (county ordinance governs). Pre-application contact with both the relevant town officials and the Pittsylvania County zoning administrator is advisable for any borderline parcel. Chatham and Gretna in particular have growth-corridor geography (along US 29) where town / county boundaries are non-obvious at the parcel level.
  • other — Unincorporated-parcel ADU projects outside the Pittsylvania County Service Authority service areas and outside the towns' service areas must budget for Virginia Department of Health well/septic evaluation and, frequently, for drainfield expansion or a dedicated secondary system — commonly adding $10,000-$30,000+ to project cost and potentially ruling out small or constrained lots where soil/slope fail percolation or reserve-drainfield requirements. Given the county's scale, most ADU projects outside the Chatham / Gretna / Hurt town service areas and the narrow PCSA corridors will face this constraint.
  • other — ADU projects that would require a new driveway entrance onto a state-maintained secondary road must obtain a VDOT entrance permit before the building permit issues; sight-distance and entrance-spacing requirements can drive ADU site selection and occasionally make a project infeasible at the originally-preferred location. Shared driveways using the existing entrance typically avoid this requirement.
  • other — ADU projects on parcels in the Blairs / northern Danville approach corridor may face airport-safety overlay height limitations that preclude certain ADU configurations (two-story ADUs, certain roof-peak heights) and may require coordination with the Danville Regional Airport Authority and, at some distances and heights, FAA Form 7460-1 notice before construction. Owners of parcels near the runway ends should consult the zoning administrator and review the applicable imaginary-surface contours at pre-application.
  • other — ADU projects on Leesville Lake shoreline parcels in the northwestern corner of Pittsylvania County must coordinate with both the Pittsylvania County zoning administrator and the AEP Smith Mountain Project shoreline-permitting office. The FERC-approved Shoreline Management Plan can restrict structure siting within the project boundary, shoreline-vegetation alteration, and dock / boathouse additions. ADU viability on a given shoreline parcel depends on the shoreline classification under the SMP in addition to county zoning.
  • other — ADU projects on river-bottom parcels along the Dan River, Staunton/Roanoke River, Banister River, or Pigg River must budget for NFIP-compliant construction (elevation above BFE plus county freeboard, flood vents, anchoring, post-construction Elevation Certificate filing). On tobacco-bottom parcels — historically prime farmland but low-lying — the elevation requirement can materially constrain ADU design and cost. Owners should confirm current-effective FIRM panels at the FEMA Map Service Center before design because FEMA has periodically updated Virginia county panels.
  • policy-review — Applicants for an ADU Special Use Permit may experience longer scheduling queues during periods of heavy solar or data-center application activity. The SUP process remains statutory (Va. Code §§ 15.2-2204, 15.2-2285, 15.2-2286) and the 60-120 day typical window reflects the best-case scheduling — complex months with contested solar or data-center hearings can push residential ADU SUPs to later agenda slots. Applicants should confirm the current Planning Commission and Board of Supervisors calendar at pre-application.
Virginia state — ADU law and programs

State ADU law

Virginia has NOT enacted a statewide ADU preemption law. Virginia is a Dillon Rule state — localities possess only those powers expressly granted by the General Assembly — and the statutes granting zoning authority (Va. Code § 15.2-2280 et seq.) leave ADU regulation to local ordinances. ADU permission, setbacks, parking, size, and owner-occupancy rules therefore vary by county, independent city, and town. Virginia is unique in that it has 38 independent cities that function as counties (neither in nor subordinate to the surrounding county), meaning 'the county' for any given Virginia property may be an independent city rather than a true county. Several ADU preemption bills have been introduced in recent General Assembly sessions (2022 through 2025) without enactment; none have advanced past committee as of the Assembly's 2026 regular session adjournment.

State financing programs

Virginia does not operate an ADU-specific statewide loan, grant, or forgivable-loan program. Virginia Housing (formerly the Virginia Housing Development Authority, VHDA — rebranded 2020) administers general first-time-homebuyer, down-payment-assistance (DPA), mortgage-credit-certificate, and rehabilitation products that can be applied to ADU-adjacent purchases or improvements when eligibility criteria are met, but none target ADU construction as a distinct product. The Virginia Department of Housing and Community Development (DHCD) administers federal HOME and CDBG pass-through funds that local jurisdictions can direct toward ADU-adjacent rehab, but there is no state-level ADU-dedicated line item. Federally available products (FHA 203(k), Fannie Mae HomeReady and HomeStyle Renovation, Freddie Mac CHOICERenovation) remain the primary ADU financing path for Virginia homeowners.

State housing programs

Virginia does not run a state-level pre-approved-ADU-plan catalog, statewide impact-fee-waiver statute for ADUs, or streamlined-review mandate. State-level programs that touch ADU-adjacent policy are coordinated primarily through the Department of Housing and Community Development (DHCD) and Virginia Housing, and act by funding or assisting local jurisdictions rather than by preemption. Local ADU activity — Arlington County's Accessory Dwellings program (detached ADUs permitted since 2008, liberalized 2020), Alexandria's accessory-dwelling ordinance, Fairfax County's accessory-living-unit program, and Charlottesville's 2021 zoning-code changes — is authorized under the localities' Va. Code § 15.2-2280 zoning authority, not by state mandate.

  • DHCD Community Development Block Grant (CDBG) Program — Federal CDBG funds administered by DHCD to eligible non-entitlement Virginia localities for community-revitalization, housing-rehab, and infrastructure projects. Not ADU-specific. Participating localities can direct CDBG funds toward housing-rehab projects where local policy supports ADUs.
  • DHCD HOME Investment Partnerships Program — Federal HOME funds administered by DHCD to Virginia participating jurisdictions and non-profits for affordable-housing acquisition, rehab, and new construction. Not ADU-specific; can be directed to ADU-adjacent rehab at local discretion.
  • Virginia Housing Commission — Permanent advisory commission of the General Assembly that studies housing-policy questions and recommends legislation. Has periodically studied ADU preemption and missing-middle housing without recommending statewide enactment as of 2026-04-21.
  • Local ADU ordinances under Va. Code § 15.2-2280 authority — Not a state program — listed here because Virginia ADU policy is executed entirely at the locality level under the § 15.2-2280 zoning grant. A homeowner seeking to build an ADU consults the zoning ordinance of the specific county, city, or town where the parcel is located.
Federal (United States) — ADU-relevant rules and programs

Federal ADU law

The United States has no federal statute that directly regulates accessory dwelling unit entitlement or design. Land-use authority over ADUs resides with states and local governments under the traditional police power. Federal engagement is limited to financing (Fannie/Freddie/FHA/VA/USDA), flood insurance (FEMA/NFIP), and discretionary housing programs (HUD), which are recorded in sibling sections of this file.

Federal financing programs

Federal housing-finance agencies and GSEs set nationwide underwriting rules that govern whether an ADU can be financed, appraised, and counted toward mortgage qualifying income. The relevant actors are Fannie Mae, Freddie Mac, FHA (HUD), VA, and USDA Rural Development.

Federal tax credits

There is no ADU-specific federal tax credit. ADUs may incidentally qualify for existing federal energy-efficiency and clean-energy tax credits when the ADU construction includes qualifying measures.

Federal housing programs

HUD administers several discretionary programs that can fund ADU-related activity at the grantee's election, but none is an ADU-specific program.
