ADU details

ADU legality: allowed-with-restrictions

Stateunclear (Virginia accessory-dwelling framework (Dillon Rule)) — Virginia has not enacted statewide ADU preemption. Va. Code Section 15.2-2280 grants counties, cities, and towns broad zoning authority. HB 1832 (2025) becomes effective July 1, 2026 and will require ADUs as a permitted accessory use in single-family residential districts; Goochland's attached-AFU regime is grandfathered, and the detached-CUP requirement is expected to be amended in 2026-2027.
Countywith-restrictions (Goochland County Code Chapter 15 (Zoning Ordinance) Article 20 Section 15-285.A) — Goochland regulates ADUs as Accessory Family Housing Units (AFUs) under Section 15-285.A. ATTACHED AFUs are by-right in A-1, A-2, R-R, R-P, R-1, R-3, R-N, R-O districts; DETACHED AFUs require a Conditional Use Permit ($750 fee). Required: occupancy by persons RELATED to a resident of the principal dwelling, no separate rental, recorded affidavit at the Circuit Court, smoke + CO detectors, and emergency vehicle access. Violation is a Class misdemeanor under Section 15-52. Size cap is qualitative ("clearly subordinate") with no published numeric cap.
Citywith-restrictions (Sandy Hook (unincorporated community along Sandy Hook Road in central Goochland County) - Goochland County zoning applies) — Sandy Hook is an unincorporated community in central Goochland County along Sandy Hook Road, the county-seat-area road that gives the Goochland Government Complex its 1800 Sandy Hook Road address. Sandy Hook Road parallels US Route 522 / Route 6 and connects the Goochland Court House village to Manakin-Sabot. The Sandy Hook community is geographically proximate to (and sometimes treated as overlapping with) the Goochland CDP itself - all county departments are in fact addressed at 1800 Sandy Hook Road. Predominantly A-1 / R-R parcels with scattered large-lot estate properties; the Sandy Hook Road corridor passes through the Goochland Historic District in places. There are no incorporated municipal limits.

Sandy Hook ADU permitting follows Goochland County Section 15-285.A directly. ATTACHED AFU by-right; DETACHED requires CUP. Sandy Hook Road parcels near 1800 Sandy Hook Road may abut the Goochland Historic District and trigger DHR review for exterior changes.

Goochland County — county ADU rules and overlays

County ADU ordinance

Goochland County's accessory-dwelling regime is the 'Accessory Family Housing Unit' (AFU) framework codified in Chapter 15 Section 15-285.A. The county distinguishes sharply between ATTACHED AFUs (by-right) and DETACHED AFUs (Conditional Use Permit required under Section 15-132). An attached AFU - a second dwelling unit contained within or attached as part of the same structure as the principal dwelling - is a permitted-by-right accessory use in the A-1 (Agricultural General), A-2 (Agricultural Limited), R-R (Residential Rural), R-P (Residential Preservation), R-1 (Residential Limited), R-3 (Residential General), R-N (Residential Neighborhood), and R-O (Residential Office) districts, subject to the Section 15-285.A development standards: (1) one additional attached unit per lot; (2) occupancy restricted to persons RELATED to a resident of the principal dwelling; (3) the second unit CANNOT be rented separately from the principal dwelling; (4) a working smoke detector and working carbon monoxide monitor must be installed and maintained in the second unit; (5) emergency vehicle access must be provided and maintained; (6) the property owner must file an AFFIDAVIT (the published Accessory Family Housing Unit Affidavit form) with the Goochland County Circuit Court Clerk recording the AFU on the land records and committing to compliance, and must provide proof of that filing to the Community Development department; on transfer, the seller must notify the purchaser in writing of the use standards and file a copy of that written notice with the department. A detached AFU is NOT by-right in any district and requires a Conditional Use Permit ($750 application fee under the published Development Review Fee schedule) reviewed by the Planning Commission and approved by the Board of Supervisors; CUP conditions typically mirror Section 15-285.A (family relation, no separate rental, safety devices, emergency access). Goochland's ordinance does NOT codify a square-foot cap on the accessory unit - the binding size constraint is the Section 15-500 definition language 'clearly subordinate to the principal dwelling unit.' Violation of the AFU standards is a Class misdemeanor under Section 15-52, with continuing violations prosecutable as separate violations and knowingly false affidavit statements punishable separately. Because Goochland's ordinance predates January 1, 2025 and does NOT deem an ATTACHED AFU a special use (only DETACHED AFUs require CUP), Goochland's attached-AFU track qualifies for the Virginia HB 1832 (2025) grandfather clause when that statute takes effect July 1, 2026 - but the detached CUP requirement likely does NOT survive HB 1832 on its face because HB 1832 requires ADUs as a PERMITTED accessory use (by-right) in single-family residential districts, which reaches detached units. A Board-of-Supervisors ordinance amendment to align the detached-AFU track with HB 1832 is expected in 2026-2027.

County regulatory overlays

Goochland County administers three principal overlay regimes that bear on accessory-family-housing-unit projects: (1) the Floodplain Overlay under Chapter 15 Article 28 tied to FEMA Special Flood Hazard Areas along the James River (the county's southern boundary) and its tributaries including Tuckahoe Creek, Lickinghole Creek, Dover Creek, Beaverdam Creek, Byrd Creek (Goochland side), and other perennial streams draining to the James; (2) conservation easements held by the Virginia Outdoors Foundation (VOF), Capital Region Land Conservancy, and other land trusts, covering over 800 acres in the county and anchored historically by the FIRST recorded conservation easement in Virginia (104 acres donated in June 1968 by James M. Ball Jr. to VOF on a Goochland parcel gifted to the University of Richmond); (3) the Land Use (use-value) assessment program administered by the Assessor's Office under Va. Code Sec. 58.1-3230, which does not restrict AFU construction but can be breached by one, removing the deferred-assessment benefit and triggering rollback taxes. Goochland is NOT a Chesapeake Bay Preservation Act locality - the county sits well west of the Tidewater Virginia boundary defined in Va. Code Sec. 62.1-44.15:68, and the James River as it passes Goochland is non-tidal main-stem river above the Richmond fall line, outside the CBPA jurisdictional footprint. Goochland has no coastal-commission jurisdiction (no Atlantic or Chesapeake coastline), no statewide WUI regulatory overlay (Virginia has none), no seismic-retrofit overlay (though the Central Virginia Seismic Zone boundary runs through nearby Louisa/Fluvanna to the west), and no Part 150 airport-noise overlay (no commercial airport inside the county; Richmond International KRIC to the east does not generate Part 150 coverage reaching Goochland parcels). Goochland has no formal county-administered Architectural Review Board with design-review authority; the county does have a Certificate of Approval process (Chapter 15) for specific site-improvement types in specific districts, but it is not a general historic-district overlay.

County permitting (unincorporated parcels)

An accessory-family-housing-unit project in Goochland County routes through the Department of Community Development, which houses both Planning & Zoning and Building Inspection divisions at 1800 Sandy Hook Road. For an ATTACHED AFU (by-right in the eight residential and agricultural districts), Planning & Zoning confirms Section 15-285.A eligibility, the property owner records the Accessory Family Housing Unit Affidavit with the Goochland County Circuit Court Clerk and provides proof of filing to Community Development, and Building Inspection issues the building permit. For a DETACHED AFU (Conditional Use Permit required), the owner first files a CUP application ($750 fee), which runs through Planning Commission public hearing and Board of Supervisors approval before the zoning and building permits can issue. For parcels not served by public water and sewer (the large majority of Goochland outside the West Creek and Tuckahoe corridor public-utility footprint), the Chickahominy Health District (Virginia Department of Health local office covering Goochland, Hanover, Charles City, and New Kent) issues the well-and-septic construction permit, which must be in hand before the county building permit is released. Applications are accepted in person at 1800 Sandy Hook Road between 8:00 a.m. and 4:00 p.m.; permits arriving after 4:00 p.m. are not accepted that day. The permit-fee calculator is published at goochlandva.us/permitcalc.

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.
