A Faster Path to a New Home
Because Mountain View has no single-family design review, a new home that meets the R1 standards goes straight to building plan check. The City estimates 5 to 8 months to permit a new home. Demolition, excavation, flood and fire sprinkler permits are issued separately.
Mountain View has no discretionary design review for single-family homes and does not require notice to neighbors. A Planning permit is needed only for exceptions such as a variance or floor-area exception, a conforming addition to a nonconforming home, exterior changes to a historic home, or lots of 10,000 sq ft or more next to a creek. Those go to the Zoning Administrator, who holds hearings on the second and fourth Wednesdays with mailed notice within 750 feet.
