ADU Rules in Chesapeake, Virginia

Chesapeake is an independent city in Hampton Roads with approximately 250,000 residents. It is one of the largest cities in the United States by land area — encompassing over 340 square miles — which makes it geographically and zonally diverse. Chesapeake ranges from dense suburban neighborhoods in its northern sections (near Norfolk and Virginia Beach) to agricultural land, wetlands, and the Great Dismal Swamp National Wildlife Refuge in the south. This diversity means that zoning context and ADU feasibility vary considerably depending on where in the city a property is located.

Virginia statewide ADU law status

Virginia has no enacted statewide ADU preemption: SB 304 of 2024 would have required ADUs by-right but was deferred to the Virginia Housing Commission and not enacted. Va. Code § 15.2-2292.1 governs only temporary family health-care structures (≤300 sq ft caregiver units), not general ADUs.

Chesapeake Local Zoning for ADUs

Chesapeake's zoning ordinance establishes residential districts including R-15S, R-12S, R-8S, and others with varying minimum lot sizes. ADUs are permitted in single-family residential zones subject to typical local standards:

• Maximum size: ADUs are generally capped at 1,200 square feet or a percentage of the primary residence; confirm current limits with the Planning Department
• Unit count: One ADU per single-family lot
• Setbacks: Detached ADUs must meet rear and side setback requirements of the applicable district; some relief may be available for small detached structures
• Height: Detached ADUs are typically limited to one story or approximately 16 feet
• Lot coverage: Combined lot coverage of the primary dwelling and ADU must not exceed the district maximum
• Owner occupancy: Virginia state law limits the owner-occupancy requirements that localities may impose
• Utilities: ADUs may be required to connect to public water and sewer where available; large-lot rural properties may qualify for separate well/septic

Rural and Agricultural Zones

A significant portion of Chesapeake is zoned agricultural (A-1) or is subject to Agricultural/Forestal District designations, which provide additional protections for farmland. These areas are generally not subject to the same ADU-by-right provisions as standard single-family residential zones. Large-parcel rural properties may be able to pursue an ADU or farm worker housing, but different standards apply. Consult the Planning Department for guidance on rural parcels.

Wetlands and Environmental Overlays

Chesapeake contains extensive wetlands, tidal marshes, and the ecologically significant Great Dismal Swamp. Many parcels near the Intracoastal Waterway, the Southern Branch of the Elizabeth River, and the North Landing River have wetland buffers and Chesapeake Bay Preservation Area (CBPA) designations under Virginia's Chesapeake Bay Preservation Act. Development — including ADUs — in the Resource Protection Area (RPA) of a CBPA designation is very severely restricted, typically limited to water-dependent uses.

If your property is near a water body, stream, or wetland, verify:

• Whether it falls in a Chesapeake Bay Preservation Area RPA or Resource Management Area (RMA)
• Whether a Virginia Department of Environmental Quality (DEQ) wetlands permit is required
• Whether any conservation easement or Agricultural/Forestal District overlay applies

Flood Zones and Sea Level Rise

Chesapeake's coastal and low-lying areas are subject to FEMA flood zone designations. Properties in Zone AE or AO must build new structures — including ADUs — at or above the Base Flood Elevation (BFE). The Hampton Roads region is experiencing relative sea level rise; Chesapeake's southern portions have areas that may be newly identified as flood-prone as FEMA updates its maps. Verify your flood zone status at msc.fema.gov and contact the city's floodplain administrator before beginning design.

Permitting Process

1. Determine zoning district — Verify your parcel's zone and any overlays on the city GIS portal
2. Check CBPA/wetlands status — Contact the city's Environmental Programs Division if near water
3. Flood zone check — Verify FEMA flood zone and BFE
4. Pre-application meeting — Chesapeake Planning Department, (757) 382-6176
5. Building permit application — Submit to the Development & Permits division
6. Inspections and Certificate of Occupancy — Required before occupancy
