Getting a Building Permit in Folsom
Folsom is a growing foothill community in Sacramento County, and residential permits are processed through the City of Folsom Building Division. 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. Folsom's neighborhoods range from established areas near the historic district to newer master-planned communities in the south. Many homes here are Craftsman-influenced or traditional two-story designs on lots that often accommodate detached ADUs or room additions. The proximity to Folsom Lake and the foothills gives the area a distinctive character compared to the flat Sacramento suburbs.
We also serve clients in El Dorado Hills, Granite Bay, Orangevale, and other communities in eastern Sacramento County and western El Dorado County.
