Virginia Beach in one screen.
- Detached guest house / limited-use ADU permitted only in the R-40 district
- Accessory structures generally 500 sf or 20% of the main home; 30% in R-30/R-40
- APZ-1 and Clear Zone rules near NAS Oceana restrict many parcels
- SB 531 will require a city-wide by-right allowance from July 1, 2027
Reading between the lines.
Virginia Beach is the most restrictive of the large Hampton Roads cities on accessory dwellings. The ordinance recognizes a detached guest house and limited-use accessory dwelling unit, but only in R-40 — the city's largest-lot single-family district. On the vast majority of Virginia Beach lots, a detached second unit is simply not a listed use today.
Two overlays shape the rest. The APZ-1 and Clear Zone restrictions around NAS Oceana limit dwelling-unit density across a large swath of the city, and Chesapeake Bay Preservation Act areas apply city-wide, constraining impervious cover and structure siting near tidal waters.
SB 531 changes the baseline in 2027. A district-limited allowance does not meet the statute's requirement that ADUs be treated as a permitted accessory use in single-family residential districts, so Virginia Beach will have to amend — though AICUZ-related restrictions are among the constraints the statute expressly preserves.
Virginia Beach answers.
Can I build a backyard ADU in Virginia Beach?
+
Only in limited circumstances today. The zoning ordinance permits a detached guest house and limited-use accessory dwelling unit within the R-40 district; elsewhere a detached second unit is generally not a listed use.
Do NAS Oceana noise zones affect ADUs in Virginia Beach?
+
Yes. APZ-1 and Clear Zone restrictions around NAS Oceana limit residential density across a large part of the city, and SB 531 expressly preserves military compatibility (AICUZ) restrictions after 2027.
Will Virginia Beach have to change its ADU rules?
+
Yes. From July 1, 2027, SB 531 requires localities to treat ADUs as a permitted accessory use on single-family lots, which a district-limited allowance does not satisfy.
