VIRGINIA BEACH, Va., October 19, 2026 – Virginia’s new accessory dwelling unit law takes effect July 1, 2027, but Hampton Roads homeowners should check their city’s rules before committing to a backyard cottage or garage apartment. Capital Valuations is highlighting two questions to answer before construction: what can legally be built, and how the finished project could affect the property’s market value.

An accessory dwelling unit, or ADU, is an additional residence on the same lot as a primary home, with its own living, sleeping, cooking and bathroom facilities. It can be attached to the main house or occupy a separate building.

The new law generally makes ADUs a permitted accessory use in single-family residential zoning districts, subject to its requirements. However, it expressly excludes localities that adopted an ADU ordinance before January 1, 2026.

That distinction matters locally. Norfolk City Council adopted amendments to its ADU regulations on September 23, 2025. Homeowners should ask their planning department which ordinance governs their address and whether their proposed use is allowed.

The state law also preserves private restrictions, including applicable HOA covenants. It allows requirements addressing matters such as parking, utilities, flooding, stormwater and military air installation compatibility. Localities may require rental terms of at least 30 consecutive days, so homeowners should not assume an ADU can operate as a short-term vacation rental.

Construction cost and added value are separate questions

Joseph T. Ellington Jr., a Virginia Licensed Residential Appraiser and owner of Capital Valuations, says a project’s construction budget should not be treated as its automatic contribution to resale value.

“What you spend on an improvement and what buyers will pay for it are two different things,” Ellington said. “Before committing to a project, you want to understand what you can build and what the local market supports.”

An ADU may provide useful space for relatives or an opportunity for rental income. Its contribution to market value still requires analysis of the property, its legal use and relevant market evidence. A contractor’s estimate alone does not establish how much more the completed property would sell for.

A garage conversion also changes more than living space. It may remove parking or storage that buyers value. The appraisal question concerns the resulting property as a whole.

What homeowners should gather before requesting a value opinion

Capital Valuations recommends starting with the property address, proposed use, local approval requirements, floor plans, dimensions and construction specifications. Homeowners seeking financing should also ask their lender what appraisal and completion documentation it requires.

An as-is appraisal addresses the property in its existing condition. An appraisal assuming a defined project is complete answers a different question. The intended use, effective date and assumptions should be agreed upon before ordering the report.

Capital Valuations explains those distinctions in its resource on as-is and as-completed appraisals:

For homeowners considering an ADU, the practical next step is to confirm the applicable rules with the local planning department, define the proposed project and evaluate its costs and potential market contribution before committing to construction.
