Richmond residents secured 105 permits for accessory dwelling units (ADUs) in 2026, marking a significant increase following citywide legalization in 2023. While interest has surged, only 41 units have received certificates of occupancy since 2020.
Why it matters
The city is promoting these units to expand housing supply after shifting its approach to neighborhood density. For homeowners, this signals a growing opportunity to add living space or rental income, though project completion remains a hurdle.
Since 2020, the city has issued 201 total permits, with 24 permits expiring during that period. Approved units can reach a maximum size of 1,200 square feet.
The details
ADUs are small secondary homes on a property that the city legalized in 2023 to eliminate the need for individual approvals. The process is intended to simplify development, though national costs for these projects typically range from $120,000 to $300,000. Richmond is currently looking into standardized building plans to help residents manage these design and construction costs.
Timeline
2020-2022: Seven accessory dwelling unit permits were recorded.
2023: Richmond legalized accessory dwelling units citywide.
2024: 31 accessory dwelling unit permits were recorded.
2025: 49 accessory dwelling unit permits were recorded.
2026: 105 accessory dwelling unit permits were recorded.
The Home Front
Richmond is following a national trend of using ADUs to address housing inventory shortages by relaxing density requirements. The city's move to standardize building designs suggests a long-term commitment to these units as a pillar of urban housing supply.
If you are planning an ADU, verify the current permitting status of your property and consult with a licensed contractor about the 1,200-square-foot limit. Keep in mind that securing a permit is only the first step, as completion requires meeting all local occupancy standards.
The takeaway
Adding an ADU can be an effective way to maximize your property's utility, provided you navigate the transition from permit to occupancy. Track the city's progress on standardized plans, as these could eventually offer a more affordable path to construction.
