What to Know About New Construction in San Mateo
Local building codes, neighborhood character, and permit requirements vary by city. Here's what San Mateo homeowners should know before starting a project.
- 01San Mateo's R1 zoning allows 40-50% lot coverage depending on the zone, with height limits of 28 feet for flat lots and special hillside regulations for properties above certain elevations in Baywood Park and Upper Hillsdale
- 02The City of San Mateo planning department processes new construction permits in 8-12 weeks — they offer pre-application meetings that can identify potential issues before you invest in full plan development
- 03San Mateo's hillside neighborhoods (Baywood Park, western San Mateo Park) may require geotechnical reports, engineered foundations, and retaining walls — these sites offer the best views but add 15-25% to construction costs
- 04San Mateo has a strong heritage tree ordinance — mature trees on your lot can influence building footprint placement and may require arborist reports and mitigation measures if removal is necessary
- 05The city requires all new residential construction to include solar panels, EV-ready wiring, and high-efficiency building envelopes per current California building code — we design these features as integral parts of the architecture
