The practical answer: beginning July 1, 2027, Virginia law will treat an accessory dwelling unit as a permitted accessory use in covered single-family residential zoning districts. That should make ADUs more predictable to pursue, but it does not eliminate local permits, building-code review, utility requirements, flood rules or private HOA restrictions.

For Hampton Roads homeowners, the best move now is preparation, not construction based on assumptions. Confirm the property's zoning, survey, utilities, flood and AICUZ conditions, then watch for local implementation guidance before paying for final plans.

What counts as an ADU under the new Virginia law?

Virginia Code Section 15.2-2292.4 defines an ADU as an attached or detached dwelling on the same residential lot as a proposed or existing primary residence. It must provide complete independent living facilities, including space for living, sleeping, eating, cooking and sanitation.

That definition is narrower than calling any shed, studio or bonus room an ADU. A detached office without a kitchen and bathroom may be an accessory structure, while an independent backyard cottage can trigger dwelling-unit, zoning and utility requirements.

What changes on July 1, 2027?

State-law changePractical meaning
ADUs become a permitted accessory use in covered single-family districtsA locality generally cannot require a special-use process beyond the requirements the statute allows.
Local ADU permit fee capped at $500Separate building, inspection, site and utility fees may still apply.
No family-relationship requirementA locality cannot require the occupants of the two dwellings to be related.
Limits on setbacks and dimensional rulesLocal ADU standards generally cannot be more restrictive than the comparisons stated in the law.

The statute also says a locality may not require a restrictive covenant for the ADU or make public-street improvements a condition, except to repair a street disturbed by construction.

What can local governments still require?

This is not a permit-free law. A locality may require a dedicated parking space, replacement of primary-dwelling parking removed by the project, and leases of at least 30 consecutive days. It may also prohibit a separate sale or subdivision of the ADU, limit ADUs on lots that already contain more than one dwelling, and require the ADU to remain within 500 feet of the primary residence.

Floor area, lot coverage and impervious-area limits remain possible, although the statute sets minimum allowed ADU sizes of 350 square feet on lots smaller than 2,500 square feet and 500 square feet on larger lots. Building code, water, sewer, septic, emergency access, flood-zone, stormwater, historic-district and AICUZ rules also remain in play.

Does the law override an HOA or every local ordinance?

No. The statute specifically preserves private contracts, recorded covenants, condominium instruments and property-owners-association declarations. A zoning approval therefore does not guarantee an HOA will allow the same project.

The law also contains important local exceptions. It does not apply to a locality that adopted an ADU ordinance before January 1, 2026, and it protects existing ADU permits approved before July 1, 2027. A locality may adopt a substantially compliant ordinance before the effective date. Homeowners should confirm how their city applies these provisions rather than assuming every Hampton Roads jurisdiction will use an identical process.

What should Virginia Beach homeowners do now?

  1. Verify zoning, lot dimensions, easements and private covenants.
  2. Review the property's survey and identify flood, stormwater and AICUZ constraints.
  3. Ask Public Utilities whether existing water and sewer capacity can serve another dwelling.
  4. Develop a realistic scope with a designer, contractor and lender before ordering final plans.
  5. Recheck the city's application, fee and parking rules closer to July 1, 2027.

Local takeaway: Virginia Beach currently requires zoning and building review for residential construction and alterations. The city's Zoning Administration and residential permit guidance are the starting points, but project-specific requirements may change as the 2027 law is implemented.
