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.

• Pittsylvania County Code — Zoning Ordinance (county code Chapter governing zoning)
• Pittsylvania County Department of Community Development — Planning and Zoning
• Pittsylvania County Board of Supervisors — adopting body for zoning ordinance amendments and Special Use Permits
• Pittsylvania County Planning Commission
• Virginia Code Title 15.2 Chapter 22 (Planning, Subdivision of Land and Zoning)
• Virginia Code § 15.2-3200 et seq. and Va. Const. Art. VII § 1 (Independent Cities)

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.

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.

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).
