What drives adu construction prices in Redwood City
Local labor, permitting and climate move Redwood City prices away from the national average.
Labor market
Licensed Redwood City contractors carry California workers' comp and prevailing wage pressure, and crews here quote roughly 43% above the national labor average. Demand in the Bay Area market peaks in spring, so booking early usually beats a rush premium.
Permits
Redwood City follows the California Building Standards Code, so most structural, electrical, plumbing and re-roof work needs a permit from the Redwood City building department plus Title 24 energy compliance. Bay Area seismic retrofit standards and strict energy upgrades are common conditions of approval.
Climate
Redwood City sits in a mild marine climate with heavy winter rain, so expect proper drainage, moisture detailing and a dry-season schedule for exterior work.
