Based on Richmond's local building codes, you'll need a permit when:
Detached ADUs (new separate structures) require full building permits including electrical, plumbing, and mechanical. Virginia has state-level ADU preemption laws that may streamline the process.
Converting an existing space (garage, basement, or other area) to an ADU requires building, electrical, and plumbing permits. The conversion must meet all residential building code requirements for habitable space including egress, insulation, ceiling height, and ventilation.
Attached ADUs (additions to the existing house) require full building permits including all trades. This is treated as a room addition with the additional requirement of meeting ADU-specific zoning rules for independent living space.
