Richmond Adopts State Height Standards for Accessory Dwelling Units

During the Richmond Planning Commission meeting on July 17, 2025, a significant discussion centered around the height regulations for accessory dwelling units (ADUs) in the city. The conversation highlighted the complexities of local versus state standards, particularly regarding the minimum height limits for these structures.

Commissioner Brubaker raised questions about whether Richmond's height standards were derived from state regulations or established independently. The response clarified that the current height limits are indeed based on state code, which sets a minimum height of 16 feet for detached ADUs. This height applies to lots with existing or proposed single-family or multifamily dwellings. For properties located within a half-mile walking distance of a major transit stop, the height can increase to 18 feet. Additionally, there is a provision allowing for an extra 2 feet to accommodate roof pitches that align with the primary dwelling.

The discussion revealed that Richmond has opted to adhere to these state guidelines without pursuing higher local limits, which could potentially allow for more versatile housing options. The existing height limit of 16 feet has been in place for approximately five years, and it was noted that this restriction makes it challenging to construct two-story ADUs.

The implications of these regulations are significant for Richmond residents, particularly as the city seeks to address housing shortages and promote more diverse living arrangements. By aligning with state standards, Richmond aims to streamline the approval process for ADUs, but this may limit the potential for innovative housing solutions that could better serve the community's needs.

As the city continues to navigate housing policies, the Planning Commission's discussions underscore the importance of balancing state mandates with local aspirations for growth and development. The next steps will likely involve further evaluations of how these height regulations impact housing availability and community planning efforts in Richmond.
