County ADU details
County ADU ordinance
Buckingham County does NOT have a standalone accessory-dwelling-unit (ADU) ordinance. The county's zoning ordinance (adopted 2018-05-15) regulates accessory structures and accessory uses through per-district permitted-use tables, with single-family detached dwellings and accessory structures and uses listed as permitted in the residential and rural districts under the one-principal-dwelling-per-lot default. The ordinance does not define 'accessory dwelling unit' as a distinct use category; a detached second dwelling typically requires either (a) a Special Use Permit, (b) subdivision of the parcel into two conforming lots, or (c) a Farm Building and Structure Affidavit path (Form available on the Building Inspections forms page) for bona fide working-farm labor housing under Va. Code § 15.2-2288. Third-party ADU-industry websites that quote flat 1,200-square-foot caps or percent-of-primary formulas for Buckingham County appear to reflect Virginia-generic template language rather than Buckingham ordinance text; the ordinance's own quantitative caps are set per-district through minimum lot size, setback, and coverage rules, plus the separate building-permit layer under the 2021 Virginia Construction Code. No statewide ADU preemption is in force in Virginia as of 2026-04-21 (per the state-adu-research file — SB 304 passed the 2024 Virginia Senate 22-18 but was sent to the Virginia Housing Commission by the House and was not enacted; subsequent preemption bills in the 2023, 2024, and 2025 sessions have not been enacted; no Virginia ADU preemption has advanced through the 2026 regular session). Buckingham's silence on ADUs is therefore the operative rule.
County permitting (unincorporated parcels)
An accessory-dwelling or second-dwelling project in unincorporated Buckingham County routes through two county departments sharing the 13380 West James Anderson Highway office. Planning & Zoning handles the Zoning Permit (the approval that must precede any Building Permit), any required Special Use Permit (the likely path for a detached second dwelling given the absence of a by-right ADU category), Rezoning (if reclassification is needed), Home Occupation Permit, and floodplain development review. Building Inspections handles the Building Permit under the 2021 Virginia Construction Code (adopted into 13 VAC 5-62 with Virginia amendments), enforces the Virginia Uniform Statewide Building Code (13 VAC 5-63), issues the Mechanical Permit, and coordinates electrical permits (2025 Electrical Permit Application on file at Planning & Zoning). Because Buckingham is overwhelmingly rural with limited public water and sewer (public-utility service is concentrated around the Buckingham Courthouse area, Dillwyn, and the courthouse-area Buckingham County Administration corridor), the Piedmont Health District (Virginia Department of Health local office covering Amelia, Buckingham, Charlotte, Cumberland, Lunenburg, Nottoway, and Prince Edward) issues the well-and-septic construction permit for parcels outside public-utility service areas via a DPOR-licensed private-sector onsite-sewage consultant (required for all applications submitted after 2019-08-11 under the VDH onsite program reform). Applications are submitted in person at 13380 West James Anderson Highway or by email to the Zoning/Planning Administrator (nedmondston@buckinghamcounty.virginia.gov) or the Building Official (transon@buckinghamcounty.virginia.gov).
County assessor
Buckingham County real estate is assessed by the Office of the Commissioner of the Revenue (Ms. Stephanie D. Love, elected constitutional officer) through a contracted third-party mass-appraisal vendor, Wampler-Eanes Appraisal Group (same vendor used for the 2020 reassessment). A general reassessment began 2024-10-09 and runs through October 2025, with new property values effective 2026-01-01; bills reflecting the new values mail in November 2025. A second dwelling or accessory-dwelling addition is captured via the supplemental-assessment process under Va. Code § 58.1-3292: on receipt of the building permit and Certificate of Occupancy from Building Inspections, the Commissioner of the Revenue's office prorates the supplemental assessment from the completion date through the end of the tax year. The primary dwelling is NOT revalued off-cycle as a result of the accessory-dwelling addition; only the new improvement is added at its assessed fair-market value. Between reassessment cycles, the Commissioner of the Revenue's office handles all real-estate assessment activity (new construction, subdivisions, zoning changes) in-house.
Assessment policy: A second dwelling or accessory structure added to a Buckingham County parcel is captured as a real-estate improvement under Va. Code Title 58.1 Subtitle III Chapter 32, specifically as a supplemental assessment under § 58.1-3292. On receipt of the building permit and Certificate of Occupancy from Building Inspections, the Commissioner of the Revenue's office adds the new improvement at its assessed fair-market value on top of the existing parcel land and improvement value. The existing primary dwelling is NOT revalued off-cycle. Buckingham has no ADU-specific assessment exemption or carve-out. Standard Virginia real-estate tax-relief programs apply: elderly and disabled relief under Va. Code § 58.1-3210 (local option implemented by Buckingham), disabled-veteran exemption under § 58.1-3219.5, and the Land Use (use-value) assessment program under § 58.1-3230 et seq. for qualifying agricultural, horticultural, forest, and open-space parcels. Real-estate supplemental assessments under § 58.1-3292 prorate from the completion date through the tax year-end.
County overlays (3)
Buckingham County administers three principal overlay regimes that bear on second-dwelling and accessory-structure projects: (1) Floodplain Zoning administered by Zoning/Planning Administrator Nicci Edmondston as Floodplain Administrator, tied to the FEMA Flood Insurance Study and Flood Insurance Rate Map for Buckingham County; this overlay reaches the James River corridor on the northern and western boundaries (the James is a State Scenic River for approximately 57 miles along Buckingham from Allens Creek to Stearnes per Va. Code § 10.1-413), the Appomattox River corridor and its tributary Holliday Creek on the southern boundary, the Willis River, the Slate River, and their tributaries. (2) the Land Use (use-value) assessment program administered by the Commissioner of the Revenue under Va. Code § 58.1-3230, which does not restrict ADU construction but can be breached by one, removing the deferred-assessment benefit and triggering up to six years of rollback taxes. (3) the James River State Scenic River corridor under Va. Code § 10.1-413, which establishes scenic-river status for the segment between Allens Creek and Stearnes running along Buckingham's northern/western boundary — this does not itself restrict private construction on riparian parcels but signals state-level interest in the corridor that often attracts conservation-easement activity. Buckingham has no coastal-commission jurisdiction (no tidal waters; well outside the Chesapeake Bay Preservation Act Tidewater boundary — the James main stem upriver of Richmond is not CBPA-covered). Virginia has no statewide WUI regulatory overlay (the state has substantial wildfire risk in its forested counties — and Buckingham is heavily forested — but no permit-constraining WUI overlay). Buckingham sits south of the Central Virginia Seismic Zone that caused 2011 damage in Louisa and Albemarle — hazard-awareness only, not a permit-constraining overlay. There is no FAA Part 150 airport-noise overlay (the nearest commercial airport, Richmond International, does not reach Buckingham; the nearest general-aviation airport is Farmville Regional in Prince Edward County). Buckingham does NOT operate a county-administered local Architectural Review Board for historic districts — National Register-listed sites in the county (including properties associated with the Historic Village at Lee Wayside and Civil War Lee Retreat Route stops) impose no private-parcel design-review constraint absent a local overlay, which Buckingham has not adopted.
Known county issues (7)
- policy-review — Prospective ADU builders in Buckingham cannot expect a fast by-right path. Pro-forma modeling must include a Special Use Permit fee plus 60-120 days of discretionary review (with conditions that may include owner-occupancy, short-term-rental limitations, size caps, or design criteria imposed by the Board of Supervisors), or a subdivision path that creates two separately taxable parcels and adds survey, plat, and recording costs. Plans sold as generic '1,200 square-foot' or '50% of primary' Virginia ADU designs (which third-party ADU-marketing sites attribute to Buckingham County) should NOT be treated as reflecting Buckingham ordinance text — the county has no such rule, and any size cap on a SUP-approved second dwelling is set by Planning Commission and Board of Supervisors conditions on the specific permit, not by ordinance. The Town of Dillwyn operates its own zoning and is not subject to county ADU practices.
- fee-schedule-pending — Pro-forma accuracy requires a direct call or email to Planning & Zoning at 434-969-4242 (nedmondston@buckinghamcounty.virginia.gov) and Building Inspections (transon@buckinghamcounty.virginia.gov, lbaird@buckinghamcounty.virginia.gov) to obtain the itemized zoning-permit, SUP, rezoning, variance, subdivision, and building-permit fees for the specific project scope. Published online templates, including third-party ADU-industry estimators, should be treated as approximate and not relied on for Buckingham-specific budgeting. The county's low permit volume and small staff (Zoning/Planning Administrator Nicci Edmondston; Building Official Tommy Ranson, CBO; Building Inspector Lexi Baird) mean phone and email access is typically responsive within a business day or two.
- other — A detached second dwelling on a rural parcel in Buckingham typically requires either an expansion of the existing septic system or a new septic system and possibly a new well for the second unit, adding a VDH-administered timeline (30-90 days for new-system evaluation) and several thousand dollars in design and construction costs beyond the county's zoning and building-permit fees. The 2019-08-11 DPOR-licensed private-consultant requirement (which replaced direct VDH soil evaluations with private-sector Authorized Onsite Soil Evaluators and Professional Engineers) adds $1,500-$4,000 to the typical pro forma and makes consultant scheduling — not county review — the rate-limiting path item. Interior or attached second dwellings served by the existing primary dwelling's septic capacity may avoid the new-system VDH layer if the system has documented reserve capacity; Piedmont Health District is the gatekeeper for that determination.
- policy-review — A second dwelling completed during the 2024-2025 reassessment window will be captured by Wampler-Eanes's field inspection (exterior photographs, measurements) rather than by a separate supplemental-assessment workflow, with the new value baked into the 2026-01-01 roll. Owners completing a second dwelling in the first half of 2026 after the reassessment effective date will receive a standard § 58.1-3292 supplemental assessment from the Commissioner of the Revenue; the supplemental is added on top of the new 2026-01-01 baseline land and improvement value. Owners appealing the 2026-01-01 reassessed value have informal review with Wampler-Eanes, then appeal to the Board of Equalization, then appeal to Circuit Court under Va. Code § 58.1-3984; deadlines are republished with each reassessment notice.
- other — A second-dwelling project on a Land Use-enrolled parcel must be sized and sited so the dwelling footprint plus curtilage does not drop the parcel below program minimums (varies by Use category: agricultural, horticultural, forest, open-space). For a typical 10-acre agricultural parcel at the 5-acre program minimum, even a modest curtilage allocation can create rollback exposure that materially affects project NPV. Owners should consult the Commissioner of the Revenue (Ms. Stephanie D. Love, 434-969-4972) before finalizing a Land Use-enrolled parcel's second-dwelling plan. Buckingham's forested character makes this a common concern.
- other — A second-dwelling project on a Dillwyn parcel must be designed to Dillwyn's town zoning and permitted through the Town of Dillwyn rather than Buckingham County Planning & Zoning. ADU practitioners targeting Buckingham County should confirm parcel location (inside vs. outside Dillwyn town limits) before applying county-ordinance rules to any pro forma. The county's Planning & Zoning Permits and Forms page does not publish Dillwyn contact information; Dillwyn's town government should be contacted directly for town-internal projects.
- policy-review — A second-dwelling project on a parcel along the James River scenic corridor — notably affecting Yogaville CDP, Wingina, Gladstone, New Canton, and the Scottsville-south-of-the-James footprint — has a materially higher probability of encountering (a) an active private conservation easement restricting additional residential structures, (b) heightened Planning Commission and Board of Supervisors scrutiny on visual-corridor grounds during discretionary Special Use Permit review, and (c) NFIP floodplain elevation requirements along the river corridor. Easement holdings should be verified against the parcel's recorded deed before pro forma; the combination of Land Use enrollment, scenic-river corridor status, and floodplain overlay makes the James River frontage parcels the most constrained second-dwelling sites in Buckingham County.
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.
