Caroline County — county ADU rules and overlays
County ADU ordinance
Caroline County permits an 'accessory dwelling' (sometimes labeled 'accessory apartment' or 'accessory family dwelling' in older ordinance text) as a supplementary use to a single-family detached dwelling on parcels of sufficient size in the county's Agricultural (RA or A-1), Rural Preservation (RP), and primary residential (R-1, R-2) districts, subject to Article V supplementary regulations. The Caroline framework follows the common central-Virginia county pattern: one ADU per parcel; the ADU must be clearly accessory (subordinate in size and use) to a principal single-family dwelling; a base size cap typically around 800 square feet with larger caps available on qualifying rural parcels of sufficient acreage; configuration options including attached, interior-conversion, and detached; the ADU must meet the principal-dwelling setbacks for the underlying district rather than reduced accessory-structure setbacks; and the ADU cannot be subdivided off or sold separately from the principal dwelling. Short-term rental of the principal dwelling or the ADU is governed by the county's separate Short-Term Rental framework. Because Virginia has no statewide ADU preemption (see state file stateAduLaw), Caroline's ordinance is the authoritative regime on every parcel in the unincorporated county; parcels inside the Town of Bowling Green or the Town of Port Royal follow those towns' own ordinances instead.
County regulatory overlays
Caroline County administers four overlay regimes that bear materially on any ADU project: (1) the Chesapeake Bay Preservation Area (CBPA) Overlay — Caroline IS a Tidewater CBPA locality under Va. Code § 62.1-44.15:67 et seq., which is an important distinction for owners coming from inland Piedmont counties; the CBPA overlay imposes a 100-foot Resource Protection Area buffer along tidal waters, tributary streams, and adjacent wetlands, with restricted development in the RPA; (2) the Floodplain Overlay District tied to FEMA-mapped Special Flood Hazard Areas along the Rappahannock River (northern boundary with Stafford County and King George County), the Mattaponi River and its North Anna / South Anna tributaries, the Pamunkey River drainage (southern boundary with Hanover County), and interior streams; (3) Fort Walker (formerly Fort A.P. Hill) federal reservation proximity — roughly 76,000 acres of federal Army garrison land in the eastern third of the county, with associated noise / access / encroachment considerations on adjacent private parcels even though Fort Walker itself is outside county zoning reach; and (4) proximity and viewshed consideration for historic resources in the Bowling Green and Port Royal town cores plus the broader Civil War landscape of the 1863 Battle of Fredericksburg / Second Battle of Fredericksburg / Chancellorsville aftermath corridors that cross into Caroline's northern sections. Caroline has no coastal-commission jurisdiction of the kind California counties administer (CBPA is a more-limited state water-quality regime, not a comprehensive coastal-development regulator), no CalFire-equivalent WUI regime (Virginia has none), and no seismic-retrofit overlay.
County permitting (unincorporated parcels)
The Caroline County Building Official issues residential building permits for every parcel in the unincorporated county. Parcels inside the Town of Bowling Green or the Town of Port Royal route through those towns' own permitting instead. An ADU permit bundle on an unincorporated-county parcel typically includes: (1) a Zoning Compliance verification / Zoning Permit from Planning and Community Development confirming the ADU meets Article V supplementary standards (size cap, one-per-parcel, principal-dwelling setbacks, district eligibility), (2) a Building Permit from the Building Official with stamped plans, (3) trade permits for Electrical, Plumbing, and Mechanical filed by licensed Virginia contractors, (4) a Virginia Department of Health construction permit for well and/or septic on the majority of parcels (Caroline's public water/sewer footprint is limited; most rural parcels require a VDH evaluation), (5) a Floodplain Development Permit if any portion of the parcel is within a FEMA-mapped Special Flood Hazard Area per the county's Floodplain Ordinance (extensive mapping along the Rappahannock River corridor, the Mattaponi River, and the Pamunkey River drainage, plus interior streams), (6) a Chesapeake Bay Preservation Area (CBPA) site plan and Resource Protection Area delineation if the parcel is within a CBPA-designated area — Caroline IS a Tidewater CBPA locality under Va. Code § 62.1-44.15:67 et seq., which is an important distinction for owners coming from inland Piedmont counties without CBPA jurisdiction, and (7) for parcels directly adjoining or inside the Fort Walker (former Fort A.P. Hill) military reservation boundary, additional coordination with the Army garrison may apply for access, utility crossings, and encroachment concerns even though Fort Walker itself is federal land outside county zoning reach.
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.
