New construction · San Mateo
Can I tear down and rebuild my house in San Mateo?
Tear-down and rebuild is allowed in San Mateo on most legally conforming parcels, but the path depends on the parcel's zoning, lot conformance, and any historic / hillside / coastal overlays. Buildable envelope shaped by FAR, side-yard daylight, and a 30-foot height limit; HR overlay adds slope-band density.
What changes the answer in San Mateo.
San Mateo uses R-1 sub-districts (with size-keyed FAR and coverage), R-2, R-3 districts plus Hillside (HR) overlays in the western areas; downtown is governed by precise plans. Most R-1 SFRs are ministerial; San Mateo Park's Architectural Review and HR-overlay parcels add design review and slope rules.
