Bay Area · San Mateo County
Golden State ADU runs a dedicated Bay Area desk that has shepherded roofing projects through El Granada's review process under city-by-city review. El Granada sits inside San Mateo County and shares the temperature swings between fog-belt mornings and inland afternoons — context that shapes every wall assembly, glazing spec, and HVAC choice we recommend. Every plan we deliver is engineered to your lot, your neighborhood overlay, and the California ADU rulebook in force this cycle.
We've delivered roofing projects across San Mateo County, with working familiarity for El Granada's zoning quirks, setbacks, height limits, and the review timelines city-by-city review actually keeps. We publish a fixed contract price the day we sign — no allowances that quietly inflate during framing.
Material, labor, and soft-cost benchmarks for the El Granada market run within the broader Bay Area band — but the spread inside that band is driven by lot access, existing utility capacity, and finish level. Our pricing is published and locked at contract, with no allowance surprises after permit. Pair the line-item estimate with our ROI and financing calculators to model a realistic payback against El Granada rents and resale comps.
El Granada review follows city-by-city review cadences. We submit a complete, code-current package on day one, respond to plan-check corrections inside the same week, and coordinate every inspection from foundation set through final occupancy. You see every plan-check comment and every response inside your project portal — no opaque "in review" weeks.
We start with a site visit: measurements, photo survey, utility verification, and a candid walk-through of what El Granada will and will not approve for roofing. From there we move to schematic design, then construction drawings, then a single permit submission with the structural, energy (Title 24), and MEP packages already coordinated. Construction is scheduled against the actual issuance date — never an optimistic guess — and you get a weekly progress note for the duration of the build.
The detailing we specify for El Granada accounts for the temperature swings between fog-belt mornings and inland afternoons. That shows up in cladding selections, flashing details around openings, attic ventilation strategy, and the way we size mini-split equipment for shoulder-season loads. Finishes are chosen for serviceability over the next decade — not just the photo shoot.
