ADU Construction in San Francisco — What We Do
California's ADU laws have transformed Bay Area properties into multi-unit assets. We design and build ADUs that comply with state ADU statutes and each city's local ordinances — from Palo Alto to San Jose to San Francisco — so the project moves fast and the finished unit holds long-term value.
San Francisco homeowners have hired us for adu construction 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.
