Home Remodeling and Construction in San Mateo, CA: Design-Build for the Peninsula’s Oldest Neighborhoods
Momentum Construction is a licensed design-build remodeling contractor (CSLB #1028128) based in nearby Belmont, serving San Mateo and the SF Peninsula since 2017. We handle kitchens, baths, additions, ADUs, roofing, flooring, painting, and outdoor living from one accountable team, so design decisions and build realities stay connected from day one.
What does San Mateo’s housing stock mean for your remodel?
San Mateo has some of the most varied housing on the Peninsula, and the right approach depends entirely on where you live. The Baywood and Aragon neighborhoods, platted in the late 1920s, are dense with 1920s and 1930s Spanish and Mediterranean revivals, Tudors, and Colonial revivals, where roughly 80 percent of homes retain their original character. Remodeling here means matching plaster textures, clay-tile roofs, arched openings, and steel casement windows rather than erasing them. Sunnybrae, by contrast, is a postwar neighborhood of ranch homes and early Eichler-style moderns from the 1950s, which respond well to open-plan kitchen reconfigurations and beam-and-post additions. Hayward Park and Hillsdale mix single-family homes with denser lots near downtown and Caltrain. We tailor framing, insulation, and finish details to each era instead of applying a single playbook.
How does permitting work in San Mateo?
Most remodels, additions, and ADUs are permitted through the City of San Mateo Building Division, which handles plan review, inspections, and the Online Permit Center. Under the city’s ADU ordinance (Zoning Code Chapter 27.19), a code-compliant ADU or JADU is reviewed ministerially, meaning a building permit without a discretionary planning hearing, provided it meets objective standards. Fire-sprinkler requirements vary by ADU type. We prepare submittals, coordinate plan check, and schedule inspections so the process stays predictable. Projects on unincorporated parcels or certain hillside lots may involve San Mateo County review instead.
Do bayfront and hillside lots need different foundations?
Yes. Homes in Shoreview, North Shoreview, and near Coyote Point sit in or near FEMA flood zones, even after the October 2024 map revision moved roughly 1,600 addresses from Zone AE to Zone X. Where flood requirements still apply, habitable space must sit at least one foot above base flood elevation, with breakaway walls and flood vents below that line. That shapes how we approach additions and raised foundations near the bay. On the higher ground of San Mateo Park and Baywood’s western edge, the constraints flip toward slope, drainage, and retaining work. We engineer each foundation to its actual site conditions.

San Mateo remodeling FAQ
Can I add an ADU in Baywood or Sunnybrae? In most single-family San Mateo neighborhoods, yes. A compliant detached or attached ADU is processed ministerially through the Building Division, though lot coverage and setbacks differ between tight 1920s parcels and larger postwar lots.
Will a flood zone stop my Shoreview addition? No, but it adds elevation and venting requirements. We confirm your current FEMA designation before design, since the 2024 map revision changed many Shoreview parcels.
Do you preserve original architecture? Yes. In Baywood and San Mateo Park especially, we match historic materials and proportions rather than replace them.
