Garage Conversions in San Mateo — What We Do
Under California ADU law, garage conversions are one of the fastest paths to added square footage. We handle the entire scope — foundation upgrades, insulation, plumbing, electrical, HVAC, and finishes.
San Mateo homeowners have hired us for garage conversions 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 Mateo permitting, construction conditions, and homeowner expectations look like.
San Mateo Permits & Process
San Mateo has streamlined ministerial review for ADUs that meet state and city standards, and a relatively efficient plan check process for typical remodels. Most kitchens and bathrooms can be permitted in 4–6 weeks; additions and ADUs in 6–10 weeks.
