Room Additions in San Francisco — What We Do
An addition done right looks like it was always part of the house. We handle structural engineering, foundation tie-ins, roofline integration, and finish matching so the new space feels native — not bolted on.
San Francisco homeowners have hired us for room additions projects across the city. As a fully licensed California general contractor (CSLB #1008964) with 11 years of Bay Area experience, we know exactly what San Francisco permitting, construction conditions, and homeowner expectations look like.
San Francisco Permits & Process
San Francisco's Department of Building Inspection (DBI) reviews structural, mechanical, electrical, and plumbing scope; the Planning Department reviews anything that adds floor area, alters the building envelope, or removes/relocates kitchens or bathrooms. Combined plan check often runs 8–16 weeks for typical residential remodels, longer if Discretionary Review is triggered. We submit complete packages the first time and respond to corrections same-week.
