County ADU details

County ADU ordinance

Nottoway 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 (A-1) and primary residential (R-1, R-2) districts. The Nottoway framework follows the common Southside-Virginia rural-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 in the 800-1,000 square-foot range with potentially larger caps available on qualifying agricultural parcels of sufficient acreage; configuration options including attached, interior-conversion, and detached on most rural parcels; 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. Because Virginia has no statewide ADU preemption (see state file stateAduLaw, citing Va. Code § 15.2-2280 et seq. as the local-zoning enabling statute and the absence of any enacted ADU floor), Nottoway's ordinance is the authoritative regime on every parcel in the unincorporated county; parcels inside the Town of Blackstone, the Town of Burkeville, or the Town of Crewe follow those towns' own ordinances instead. The ordinance text varies in terminology across amendment cycles ('accessory dwelling', 'accessory apartment', 'accessory family dwelling' have all appeared); confirm the current text with the Nottoway County Planning office before relying on a specific size threshold or configuration rule.

County permitting (unincorporated parcels)

The Nottoway County Building Official issues residential building permits for every parcel in the unincorporated county. Parcels inside the Town of Blackstone, the Town of Burkeville, or the Town of Crewe 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 Zoning confirming the ADU meets the supplementary-regulation 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 — Nottoway's public water/sewer footprint is limited to town areas, so 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 (mapping along the Nottoway River corridor — south county boundary with Lunenburg and Brunswick — and along Sandy River, West Creek, and Little Nottoway River drainages), and (6) for parcels directly adjoining or inside the Fort Barfoot (formerly Fort Pickett) military reservation boundary, additional coordination with the Virginia Army National Guard garrison may apply for access, utility crossings, and encroachment concerns even though Fort Barfoot itself is federal/state-military land outside county zoning reach.

County assessor

Nottoway County real estate is assessed through the Nottoway County Commissioner of the Revenue's office in coordination with the county's contracted general-reassessment process. Virginia's statutory default is a four-year general reassessment cycle under Va. Code § 58.1-3252; smaller-population counties may operate on six-year cycles. Nottoway has historically used a six-year cycle, with the precise current cadence set by Board of Supervisors action. Between general reassessments, supplemental assessments capture new construction and major improvements at the completion date under Va. Code § 58.1-3292. An ADU addition is captured through this real-estate-improvement supplemental process: when the Building Official issues the Certificate of Occupancy, the record flows to the Commissioner of the Revenue, which prorates the supplemental assessment from the completion date through the end of the tax year, adding the ADU's assessed value to the parcel's land-and-improvement base. The primary dwelling is NOT revalued off-cycle as a result of the ADU addition; the next general reassessment re-bases the full parcel at the new cycle's valuation date.

Assessment policy: An ADU addition is captured as a real-estate improvement under Va. Code Title 58.1 Subtitle III Chapter 32. The Commissioner of the Revenue receives the Certificate of Occupancy and building-permit record from the Building Official and issues a supplemental assessment prorated from the completion date through the end of the tax year (Va. Code § 58.1-3292). The ADU is added at assessed fair-market value (typically cost-approach-derived using Marshall & Swift residential cost multipliers at the current reassessment-cycle base) on top of the parcel's existing land and improvement value; the existing primary dwelling is NOT revalued off-cycle. Nottoway has no county-specific ADU assessment exemption. Standard Virginia real-estate tax relief programs apply to the parcel as a whole: elderly-and-disabled relief under Va. Code § 58.1-3210 (local-option thresholds set by the Board of Supervisors, with Nottoway operating a senior-and-disabled tax-relief program with income and net-worth ceilings published annually), and the disabled-veteran exemption under Va. Code § 58.1-3219.5 (100% statutory for qualifying veterans — a particularly relevant exemption in Nottoway given the Fort Barfoot / former Fort Pickett military community). Land-use-assessment valuation under Va. Code § 58.1-3230 et seq. is available on qualifying agricultural, horticultural, forest, and open-space parcels; Nottoway has a substantial land-use-assessment population given its agricultural and forestry economy.

County overlays (3)

Nottoway County administers a smaller overlay portfolio than tidewater or Northern Virginia counties: (1) the Floodplain Overlay District tied to FEMA-mapped Special Flood Hazard Areas along the Nottoway River (south boundary with Lunenburg and Brunswick Counties), the Little Nottoway River, Sandy River, West Creek, and other interior streams; (2) Fort Barfoot (formerly Fort Pickett) federal/state-military reservation proximity — the Maneuver Training Center occupies a substantial portion of the eastern county and crosses into Brunswick, Dinwiddie, and Lunenburg as well, with associated noise / access / encroachment considerations on adjacent private parcels; and (3) limited historic-resource sensitivity around Nottoway Court House (the historic county seat with 19th-century courthouse and supporting buildings), Blackstone's town core, and scattered National Register properties. Nottoway is NOT a Tidewater Chesapeake Bay Preservation Area locality — the CBPA program reaches Tidewater localities under Va. Code § 62.1-44.15:67 et seq., and Nottoway sits inland in the Southside Piedmont, well west of the Tidewater Chesapeake Bay drainage area used to define CBPA jurisdiction. Nottoway has no coastal-commission jurisdiction, no CalFire-equivalent WUI regime (Virginia has none), and no seismic-retrofit overlay.

Known county issues (2)

  • other — For ADU research purposes this is a labeling-only issue — the installation continues to be federal/state-military land outside county zoning, with the same adjacent-parcel compatibility considerations (noise, access, ACUB encroachment-prevention offers) as before the rename. Consultants using older source documents should cross-reference both names when searching for property records, noise-exposure disclosures, or encroachment-easement status on parcels adjacent to the installation boundary. Note that Fort Barfoot's training cycle (Guard weekend drills, two-week annual training, periodic mobilization rotations) produces a different noise pattern than active-duty Army installations like Fort Walker — Guard training is typically more episodic and concentrated in summer months.
  • policy-review — Any ADU pro forma using thresholds from this research file should be reconfirmed against the current Nottoway County Code text published on Municode at library.municode.com/va/nottoway_county or by direct inquiry with Nottoway County Planning and Zoning before commitment. Particular attention should go to (a) the family-relationship condition (if any), (b) the base size cap and any rural-large-lot allowance, and (c) which districts list ADU as a permitted or special-use accessory use. Consultants pricing an ADU project should plan a pre-application zoning inquiry as the first design-cycle activity rather than relying on third-party summaries.
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.
