Getting a Building Permit in Oakland
Oakland is the county seat of Alameda County, and residential permits are processed through the City of Oakland Planning and Building Department. We prepare plans for submittal to the local building department and manage plan check corrections through approval.
Our process includes a site visit and measurements, design, construction drawings, structural and Title 24 energy coordination, submittal, and corrections. Oakland has a rich variety of housing — Craftsman bungalows and Victorian homes in Temescal and Rockridge, mid-century ranches in the flatlands, and hillside homes in the Oakland Hills with views and complex terrain. ADU projects are common across the city, and fire rebuild work is relevant in the hills following past fire events.
We also serve clients in Berkeley, Emeryville, Piedmont, San Leandro, and other communities in Alameda County.
