County ADU details
County ADU ordinance
Greensville County does NOT maintain a standalone accessory-dwelling-unit ordinance with dedicated definitional and dimensional standards. ADUs in Greensville County are regulated indirectly through the Zoning Ordinance's treatment of 'accessory uses,' 'accessory structures,' 'guest house / guest cottage,' and 'family-occupied second dwelling' in combination with the per-district use schedules. The relevant districts are A-1 Agricultural (the principal large-lot rural district covering most of the county), A-2 Agricultural Limited, R-1 and R-2 Residential, R-MF Multifamily Residential (limited footprint), B-1 and B-2 Business, M-1 Industrial, and a few specialized districts. In the A-1 and A-2 Agricultural districts, which cover the great majority of county acreage, a 'family-member dwelling' or farm-labor tenant dwelling is typically permitted subject to minimum lot area, demonstrated agricultural or family-member use, and Zoning Administrator approval; a fully independent second dwelling for non-family occupancy typically requires a Special Use Permit from the Board of Supervisors after Planning Commission recommendation. In the R-1 and R-2 Residential districts (smaller residential parcels closer to Jarratt and the Emporia fringe), accessory-structure rules apply with district-specific setback standards. Applicants should confirm current ordinance text with the Department of Planning before committing to a project pro forma. Greensville County's economic profile is dominated by tobacco-belt agriculture (historically), forestry, the Greensville Correctional Center (a major employer), and I-95 corridor commercial activity (truck stops, distribution, and services) - the county has experienced sustained population stagnation, with current population approximately 11,000.
County permitting (unincorporated parcels)
Greensville County's Department of Planning handles zoning, Special Use Permits, site plan review, subdivision review, and Floodplain Overlay administration for every parcel in the county except those inside the Town of Jarratt and the City of Emporia (which administer their own permitting). Building Inspections issues building permits and trade permits for the same non-town territory. A typical ADU-like permit bundle includes: (1) a Special Use Permit from the Board of Supervisors with Planning Commission recommendation, unless the parcel qualifies for an A-1 / A-2 family-member or farm-labor dwelling allowance, (2) a Zoning Permit confirming use compliance and district setback compliance, (3) a Building Permit with stamped residential plans, (4) Electrical, Plumbing, and Mechanical trade permits, (5) a Virginia Department of Health Crater Health District construction permit for well and/or septic on parcels not served by public water or sewer (which is the great majority of parcels - public water and sewer service is limited to the Emporia fringe and a few service-district extensions), (6) a Floodplain Development Permit if any portion of the parcel is within the mapped Special Flood Hazard Area along the Meherrin River, the Nottoway River drainage, Three Creek, or other tributaries, (7) limited Chesapeake Bay Preservation Act applicability - Greensville County is generally NOT a designated Tidewater locality under the CBPA (the Tidewater designation generally applies east of the Fall Line, and Greensville is in the southern Coastal Plain which is sometimes designated and sometimes not depending on the watershed analysis; verify current CBPA status with the Department of Planning before assuming applicability), and (8) US Army Corps of Engineers permit where federal waters or jurisdictional wetlands are involved (the southern Virginia Coastal Plain has substantial Section 404 jurisdictional wetlands particularly along the Roanoke River drainage and the smaller blackwater-creek systems).
County assessor
Greensville County real estate is assessed by the Office of the Commissioner of the Revenue working with the Real Estate Assessment Office. Greensville County operates on a periodic general-reassessment cycle under Va. Code Section 58.1-3252; the county uses a multi-year cycle. An ADU or second-dwelling addition is captured through the supplemental real-estate-improvement process under Va. Code Section 58.1-3292. State-managed land at the Greensville Correctional Center and other state facilities is not on the local rolls.
Assessment policy: An ADU is captured as a real-estate improvement under Va. Code Title 58.1 Subtitle III Chapter 32. On receipt of the building permit and Certificate of Occupancy, the Real Estate Assessment Office prorates the supplemental assessment under Va. Code Section 58.1-3292. The ADU is added at its assessed fair-market value; the existing primary dwelling is NOT revalued off-cycle. Standard Virginia tax-relief programs (elderly/disabled under Va. Code Section 58.1-3210, disabled veterans under Va. Code Section 58.1-3219.5) apply. Land Use Assessment under Va. Code Section 58.1-3229 et seq. is locally adopted and is consequential in Greensville County for working farmland (historically tobacco, increasingly soybeans, corn, cotton, and silviculture).
County overlays (3)
Greensville County administers limited overlay regimes that bear on ADU projects. The relevant overlays are: (1) a Floodplain Overlay District tied to FEMA Special Flood Hazard Areas, with material coverage along the Meherrin River, the Nottoway River drainage to the north, Three Creek, Fontaine Creek, and other blackwater-creek tributaries; (2) Section 404 Clean Water Act jurisdictional wetlands across portions of the county where blackwater-creek and bottomland-hardwood systems create federally-jurisdictional wetlands; (3) state land at the Greensville Correctional Center (a Virginia Department of Corrections facility) and other state-managed parcels; (4) limited local historic resources, primarily NRHP-listed plantations and rural-vernacular buildings scattered across the county. Greensville County is generally NOT a designated Tidewater locality under the Chesapeake Bay Preservation Act (the county is in the Roanoke River / Albemarle Sound drainage rather than the Chesapeake Bay watershed; verify current CBPA status with the Department of Planning). Greensville has NO California-style coastal commission, NO CalFire-equivalent WUI regulatory overlay, and NO seismic-retrofit overlay.
Known county issues (4)
- other — ADU pro formas that would pencil as by-right or ministerial projects in jurisdictions with codified ADU ordinances require a discretionary SUP cycle in Greensville County. This adds roughly 90-150 days of wall-clock and a separate SUP application fee ($300-$1,000).
- other — ADU economics in Greensville are typically driven by family-occupancy use cases (housing for extended family) rather than by long-term-rental or tourism-tied demand. Applicants underwriting an ADU pro forma based on long-term rental income should be conservative on assumed occupancy rates and rent levels.
- other — Wetland delineation costs $2,000-$8,000; mitigation purchase from an approved mitigation bank can run $10,000-$50,000 per acre of impact. ACOE Section 404 review adds 30-180 days. Applicants on parcels adjacent to any blackwater-creek system should commission a wetland delineation before pricing a project.
- other — Applicants should verify jurisdiction at the Commissioner of the Revenue's parcel-lookup page or the GIS portal before applying for permits. Filing the wrong jurisdiction's application can cost weeks of wall-clock and may require re-filing the application from scratch.
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.
