ADU details
ADU legality: allowed-with-restrictions
Hampton allows ADUs by-right in all one-family residential districts subject to ordinance standards - notably more permissive than rural Virginia counties. CBPA RPA overlays apply along Chesapeake Bay frontage and tidal tributaries; floodplain and storm-surge constraints are significant given the city's coastal exposure.

Legal history (timeline)
Current ordinance: City of Hampton Zoning Ordinance (Chapter 3 - Uses Permitted; Section 2-2 ADU definition), adopted 1952-01-01, last amended 2023-09-13
- 1610-01-01 — Hampton founded as Kecoughtan, one of the oldest English-speaking settlements in North America (private-development)
Hampton was founded by English colonists in 1610 as Kecoughtan, and is one of the oldest continuously inhabited English-speaking communities in North America.
Effect: Deep historic-resources context that shapes preservation overlays in older Hampton neighborhoods (Phoebus, Old Hampton, Wythe). - 1952-07-01 — Hampton consolidated with surrounding Elizabeth City County (state-statute)
In 1952, the City of Hampton consolidated with surrounding Elizabeth City County (and the town of Phoebus), expanding the city's geographic boundary substantially.
Effect: Modern Hampton city boundary established; ADU policy applies to a much larger geographic area than the pre-1952 historic city. - 1988-07-01 — Chesapeake Bay Preservation Act applies to Hampton (state-statute)
Hampton is fully within the Tidewater region; CBPA RPA buffers (100 ft) apply along Chesapeake Bay frontage, Back River, and tidal tributaries.
Effect: RPA buffer constraints affect ADU siting on a significant share of city parcels. - 2023-09-13 — Hampton City Council amends Zoning Ordinance to permit ADUs in all one-family residential districts (city-ordinance)
Hampton City Council amended the Zoning Ordinance to add a formal ADU definition and permit accessory dwelling units in all one-family residential properties subject to ordinance standards.
Effect: Significantly broader ADU permissibility in Hampton than in most Virginia jurisdictions; the amendment positions Hampton as one of the more ADU-friendly Hampton Roads cities.
Known issues (2)
- other — Adds significant flood-elevation and engineering cost; some parcels are not buildable for new dwellings.
- other — Property values in highest-noise contour zones are lower; ADU livability may be affected.
Newport News (independent city) — county ADU rules and overlays
County ADU ordinance
Newport News adopted an Accessory Dwelling Unit ordinance in September 2024 (effective October 1, 2024) that PERMITS ADUs as a use within all zoning districts in which single-family dwellings are permitted. The ordinance is one of the more permissive ADU regimes in Tidewater Virginia. Per the City Council action: ADUs are smaller, self-contained living spaces with their own kitchen, bathroom, and living areas, created by converting garages, building carriage houses, or adding in-law suites; size and height limits apply; the ADU must match the architectural style of the primary residence. Specific numeric size caps, owner-occupancy provisions, parking requirements, and short-term-rental treatment are codified in the Chapter 45 Zoning Ordinance amendment text and the Codes Compliance implementing materials. Confirm current ordinance text with the Department of Planning at 757-933-2311 and the Codes Compliance permit office before architectural design — the ordinance is recent (2024) and post-adoption administrative interpretation continues to evolve. Newport News took the legislative step that many Virginia localities have not: by-right ADU permission in single-family-permitted districts, motivated by 'pro-growth' housing-supply policy in a city that City Council described as 'essentially built out.'
County regulatory overlays
Newport News administers a Floodplain Overlay tied to FEMA Special Flood Hazard Areas — given the city's lower-elevation Tidewater geography and extensive shoreline along the James River, Hampton Roads, Warwick River, and other waterbodies, a substantial share of parcels are in-mapped SFHA, including coastal high-hazard (V / VE) zones along Bay-facing reaches. The Chesapeake Bay Preservation Area Overlay covers the entire city under the Chesapeake Bay Preservation Act. Joint Base Langley-Eustis spans into Newport News and creates an FAA / Department of Defense airspace and noise-coordination overlay around Langley Air Force Base operations and Joint Base Langley-Eustis Army aviation. Newport News / Williamsburg International Airport (PHF) generates an FAA Part 150 noise contour reaching adjacent neighborhoods. The Newport News Shipbuilding industrial waterfront and the Hampton Roads port generate significant industrial-residential adjacency in older neighborhoods. Newport News has NO designated coastal-commission analog beyond the CBPA / VMRC / Army Corps stack, NO statewide WUI regulatory overlay, and NO seismic-retrofit overlay.
County permitting (unincorporated parcels)
A typical ADU permit bundle in Newport News under the 2024 ordinance includes: (1) pre-application zoning inquiry to confirm by-right eligibility and review architectural-compatibility requirements, (2) zoning permit confirming ADU use compliance and Chapter 45 performance standards, (3) Chesapeake Bay Preservation Act review (Newport News is a designated Tidewater locality under the CBPA; RPA / RMA buffer review applies on parcels with proximity to the James River, Hampton Roads, Lake Maury, the Warwick River, and other waterbodies), (4) building permit application via the Citizen Self Service Portal at the Department of Codes Compliance with stamped residential plans complying with the 2021 Virginia Construction Code (Part I of the Virginia USBC, effective January 18, 2024), (5) electrical, plumbing, mechanical, and (where applicable) fuel gas, fire protection, and elevator trade permits, (6) connection to city water and sewer (Newport News Waterworks and Hampton Roads Sanitation District; the city is fully served by public utilities — well and onsite septic are essentially absent in the modern city), (7) floodplain development permit where the parcel is within the FEMA Special Flood Hazard Area (much of the lower-elevation city near tidal water is in-mapped), and (8) erosion-and-sediment-control / land-disturbance permit (Tidewater 2,500 sqft threshold).
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.
