ADU Construction Services in Virginia Beach
RBC Homes operates as a residential contractor in Virginia Beach, VA, serving homeowners interested in accessory dwelling units (ADUs) and related backyard structures. An ADU is a smaller, independent living space built on the same lot as a primary residence, often used for rental income, housing family members, or creating additional private living space.
Homeowners in Virginia Beach should be aware that ADUs are only permitted under limited zoning conditions, specifically within R-40 residential districts. Many standard residential zones, including R-5, R-7.5, and planned unit developments, do not currently allow accessory dwelling units. Because of these restrictions, RBC Homes recommends that property owners confirm zoning eligibility with the Virginia Beach Planning Department before moving forward with any ADU project.
Types of ADUs and Alternative Structures
For properties where ADUs are permitted, several formats are commonly considered, each with different construction requirements:
- Detached units – standalone backyard cottages built separately from the main house, typically including their own entrance, kitchen, and bathroom.
- Attached units – additions or garage conversions connected to the main home, often sharing utilities and at least one wall with the primary structure.
- Interior conversions – basements or attics renovated into livable space, requiring separate entrances, adequate ceiling height, and proper egress.
- Repurposed structures – existing sheds, workshops, or outbuildings upgraded to meet Virginia Residential Code standards for structural integrity, insulation, and utilities.
- Modular or prefab units – factory-built structures delivered and installed on a prepared foundation, offering more predictable timelines and costs.
Given the zoning limitations on true ADUs in most Virginia Beach neighborhoods, RBC Homes also builds permitted alternatives such as pool houses, detached garages designed for guest use, and custom workshops. These structures can provide additional functional space on a property without requiring ADU zoning approval.
Zoning Considerations Before Building
Beyond confirming the correct zoning district, homeowners working with a contractor on an ADU or similar structure need to account for setback requirements, lot coverage limits, and size restrictions. General guidelines in Virginia Beach include rear yard setbacks of 5–15 feet, side yard setbacks of 5–10 feet, and a minimum separation of roughly 10 feet between a detached unit and the main dwelling. Maximum ADU size is typically capped at 800 square feet or 50% of the primary home's living area, whichever is smaller, with height generally limited to 25 feet or two stories.
RBC Homes works within these local building codes and zoning parameters when planning construction projects for Virginia Beach homeowners, whether the end result is a code-compliant accessory structure or a qualifying ADU in an eligible district. Because regulations can vary based on lot size, existing structures, and intended use, property owners are encouraged to consult directly with RBC Homes or the local zoning office to determine what is achievable for their specific property.
