Richmond Community Development Unveils New ADU Guidebook and Legislative Changes

The Richmond Planning Commission convened on July 17, 2025, to discuss significant updates regarding accessory dwelling units (ADUs) in the city. The meeting focused on recent changes to state ADU laws and the introduction of a new guidebook aimed at simplifying the application process for residents.

The discussion began with a presentation highlighting the consolidation of ADU regulations into a single section of the government code, as mandated by Senate Bill 477. This change is intended to streamline the understanding of ADU laws for both residents and city officials. Additionally, Assembly Bill 2533 and Senate Bill 1211 introduced new definitions and guidelines concerning livable space and parking requirements. Notably, the new regulations state that uncovered off-street parking spaces demolished during ADU construction do not need to be replaced, easing some of the burdens on homeowners.

The presentation also outlined procedural changes for processing ADU applications. The city is required to make decisions on applications within 60 days, and if an application is denied, the city must provide a clear explanation. For applications utilizing preapproved detached ADU plans, the approval timeframe is reduced to 30 days, expediting the process for homeowners.

To assist residents, the Community Development Department has developed an ADU guidebook, which is available online. This guidebook includes preapproved plans that allow homeowners to bypass initial planning reviews and proceed directly to obtaining building permits. The guidebook is designed to be user-friendly, and officials encouraged residents to utilize it for their ADU projects.

The meeting concluded with a recommendation for the commission to hold a public hearing and adopt a resolution to approve zoning amendments related to ADUs and junior accessory dwelling units, as detailed in the staff report. The updated regulations and guidebook are expected to facilitate the construction of ADUs in Richmond, addressing housing needs and providing more options for residents.

Overall, the meeting underscored the city's commitment to enhancing housing opportunities through streamlined processes and clear guidance for accessory dwelling units.
