Getting a Building Permit in Fremont
Fremont is one of the largest cities in Alameda County, and residential permits are processed through the City of Fremont Development and Building Services. We prepare plans for submittal to the local building department and manage plan check corrections through approval.
Our process covers site visit and measurements, design, construction drawings, structural and Title 24 energy coordination, submittal, and corrections. Fremont's neighborhoods include a mix of mid-century homes in Centerville and Irvington, newer developments in Mission San Jose, and hillside properties in the Niles and Warm Springs areas. ADU projects are popular here, particularly in neighborhoods with larger lots that can accommodate detached backyard units.
We also serve clients in Newark, Union City, Hayward, Milpitas, and other communities in southern Alameda County and northern Santa Clara County.
