Turn Your Daly City Garage Into a Real, Permitted ADU
Built right, slab and all.

Here's the part nobody mentions on the cheap quotes. A garage slab is typically un-rated, sits on shallow footings, and slopes down toward where the door used to be — it was built to drain a wet car, not to hold a heated, framed, occupied room. For habitable use we almost always either underpin the existing footings or pour a new slab with proper footings, vapor barrier, and a level finish floor. In Westlake's hillside tract homes — many on stepped or downhill foundations — that grade difference can be six inches across the room. We measure it, price it honestly, and tell you before you sign, not after we've opened the floor.

Permits run through the City of Daly City, and I'll be straight — Bay Area permitting is slower and pricier than what we see at home in Sacramento. Power is PG&E, and a habitable conversion means a real electrical plan, often a panel upgrade, plus heat, plumbing, and proper ventilation. Then there's the thing on the map: the San Andreas Fault runs right along the west edge of town — the lake sits in the fault valley — so seismic design and Alquist-Priolo fault-zone setbacks are genuine inputs, not paperwork. A detached garage near a lot line can also trigger fire-rated wall assemblies. We engineer for all of it and carry the plans through review for you.
