Development Plan for a Small Lot Design Review for Detached Pergola, County File #CDDP25-03019

The Development Plan for a Small Lot Design Review, identified as County File CDDP25-03019, is managed by the Contra Costa County Department of Conservation and Development. The project is located at 4010 Wellington Place, Lafayette, California, and seeks a Development Plan permit to allow for the issuance of building permits for an as-built 370-square-foot detached pergola. This action is necessary because the structure is situated on a lot with a substandard average width of 109 feet, which is below the minimum requirement of 120 feet. The project is categorized as an accessory structure to an existing single-family residence and has been granted a California Environmental Quality Act exemption under Section 15303(e) for the new construction or conversion of small structures. The lead agency for this project is the Department of Conservation and Development, with Chloe Partain serving as the Project Planner. Administrative filings were completed on December 4, 2025, and the process includes required fees for the County Clerk and the Department of Fish and Wildlife.
