Axiom Renovation in San Mateo

Axiom Renovation is a licensed general contractor (CA Lic. #1105006) serving San Mateo with ADUs, kitchen and bathroom remodels, second-story additions and new homes.

San Mateo’s neighborhoods include Baywood, subdivided from the Parrott estate starting in the mid-1920s with period-revival homes in Spanish, Mediterranean, Tudor and Cape Cod styles followed by postwar ranches, and Glazenwood, with early-1920s Spanish Colonial Revival homes. We plan each project around the house’s era and San Mateo’s design guidelines.

How San Mateo Reviews Home Projects

San Mateo’s Single-Family Dwelling Design Review applies to new two-story homes, replacement homes, any second story on a one-story home, and second-story additions over 50 sq ft on a two-story home. Small additions to two-story homes, up to 200 sq ft or 20% of floor area, can go straight to a building permit. Permits and inspections run through the City’s online Customer Self-Service portal, and San Mateo Consolidated Fire handles fire review.
