ADU details
ADU legality: allowed-with-restrictions
ADUs allowed in R-2/R-3 districts by-right with size and owner-occupancy conditions; R-1 ADUs require Conditional Use Permit. Petersburg's significant historic-district overlay (covering much of Old Towne) adds Architectural Review Board approval to most ADU projects in the historic core. Post-July 2027 SB531 may compel by-right detached ADUs unless city pre-empts.

Legal history (timeline)
Current ordinance: City of Petersburg Zoning Ordinance (Code Chapter 110) — accessory apartment provisions, adopted 2020-07-21, last amended 2020-07-21
- 1748-12-17 — Petersburg established as a town by the Virginia General Assembly (local-ordinance)
Petersburg established as a town in 1748, named for Peter Jones, a trading post operator. Incorporated as a city in 1850.
Effect: Establishes Petersburg as an independent Virginia municipality with city zoning authority. - 1865-04-03 — Petersburg post-Civil War rebuilding — Old Towne Petersburg Historic District established (NRHP 1980) (local-ordinance)
Petersburg endured a 9.5-month siege during the Civil War (June 1864 to April 1865), the longest of the war. Post-war rebuilding produced the rich Victorian-era housing stock that now constitutes the Old Towne Petersburg Historic District (listed NRHP 1980), one of the largest historic districts in Virginia.
Effect: Creates extensive historic-overlay zoning that controls ADU architectural design throughout Old Towne; Architectural Review Board review required for visible exterior changes. - 2020-07-21 — Petersburg Zoning Ordinance — accessory apartment provisions (local-ordinance)
City zoning ordinance permits accessory apartments in R-2 / R-3 districts by-right with size cap and owner-occupancy; R-1 accessory apartments require Conditional Use Permit. Provisions pre-date SB531 January 1, 2026 exemption deadline.
Effect: Likely satisfies SB531 exemption for attached/within-structure ADUs; detached-ADU treatment may still be challenged by SB531 post-2027. - 2026-04-14 — Virginia SB531 — statewide by-right ADU mandate signed by Governor Spanberger (state-law)
SB531 signed by Governor Spanberger, effective July 1, 2027. Mandates by-right ADUs in single-family zones, caps permit fees at $500, prohibits stricter setbacks than principal dwelling. Localities with ADU ordinances in place by January 1, 2026 are exempt.
Effect: Petersburg's existing accessory-apartment ordinance covers attached units; SB531 detached-ADU mandate may apply unless city adopts a compliant pre-2027 ordinance amendment.
Known issues (3)
- policy-review — Historic-district ADU projects face design and timeline burden, partially offset by federal+state historic tax credits when undertaking substantial rehabilitation.
- staffing-shortage — Plan-review cycles often exceed 3; owners should budget extra time for permit issuance.
- policy-review — CUP process adds 3-6 months and ~$2500 in fees; converting attic/basement or building attached addition is the lower-friction path.
County: no attribution (synthetic bucket)
No county
This city sits in the state's "no county" bucket — its ADU rules derive directly from state law and city ordinance without a county intermediary. No county-level sections apply.
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.
