ADU details
ADU legality: allowed-with-restrictions
Stephens City is a small historic town within Frederick County. Town and County both permit accessory apartments with restrictions. Until July 1, 2027 (SB531 effective date), local rules control - and the small lot sizes typical in the town's historic core make detached ADUs impractical without lot consolidation. After 2027, the $500 fee cap will apply.

Permitting process
Viability (permitted uses)
- Long-term rental: yes Long-term rental is the dominant practical use; demand is modest but stable given proximity to Winchester employment.
- Short-term rental: with-restrictions Stephens City does not host a major STR market; what STR activity exists is occasional weekend rental tied to Civil War battlefield tourism (Cedar Creek, Kernstown) and Shenandoah Valley wine-trail visitors. Town would require a business license.
- Office rental: no ADU must remain a dwelling unit.
- Home office: yes Home occupation permitted under town standards with no employee-visit traffic.
- Studio / workshop: yes Personal studio/workshop use is permitted accessory use.
- Agriculture: with-restrictions Limited within town limits; permitted on rural-edge parcels and unincorporated Frederick County land.
- Relative support: yes Family-occupancy accessory apartment is the most common Stephens City use case; aging-in-place is the dominant driver.

HOA prevalence & preemption
Historic core of Stephens City (pre-1900 lots) is rarely HOA-governed. Newer subdivisions on the town edge built post-1980 frequently have HOAs with their own ADU restrictions. SB531 (2027) does not preempt HOA private covenants.
Regulatory overlays (1)
- historic-district
Stephens City has a designated historic district encompassing much of the original Main Street (US-11) corridor; exterior changes within this district may trigger town architectural review for visible alterations. ADUs inside the historic district require special attention to streetscape compatibility.

Legal history (timeline)
Current ordinance: Town of Stephens City Zoning Ordinance, adopted varies-by-amendment, last amended 2024-XX-XX
- 1758-01-01 — Stephens City founded as Stephensburg (town-charter)
Lewis Stephens founded Stephensburg; one of the earliest chartered towns in the Shenandoah Valley.
Effect: Established historic town footprint; many lots in the original survey predate modern zoning. - 2024-07-01 — Virginia HOA disclosure modernization (HB-various) (state-law)
Annual HOA disclosure-packet modernizations; not ADU-specific but affects HOA-governed subdivisions adjacent to Stephens City.
Effect: Procedural; minor effect on ADU disclosure if HOA covers the parcel. - 2026-04-14 — Virginia SB531 signed - statewide by-right ADU mandate (state-law)
Effective July 1, 2027: by-right one ADU per single-family lot statewide, $500 permit-fee cap, January 1, 2026 grandfather clause for stricter ordinances already in force.
Effect: Will preempt portions of the Stephens City and Frederick County rules in 2027; current town-imposed setbacks and parking minimums that pre-date 2026-01-01 are grandfathered.
Known issues (2)
- staffing-shortage — Town zoning staff is part-time / limited; applicants often deal directly with Frederick County for building-permit functions. Coordination friction can extend timelines.
- other — Lot-size constraint - typical lot sizes in the historic core (5,000-9,000 sqft) make detached ADUs impractical without lot consolidation or front/rear setback variances.
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.
