Setback Rules: Martinez vs San Ramon

Martinez front yard setbacks vary by zoning district, typically 20 feet in standard single-family zones (R-1) measured from the front property line to the nearest point of the structure. Porches, eaves, and bay windows may project limited distances into the setback. Corner lots have setbacks on both street frontages.

Corner lots in San Ramon have two street-facing yards, both of which are treated as front yards for setback purposes. Typically the primary front yard retains the full 20-foot setback, while the street-side yard requires a reduced but still substantial setback (often 10–15 feet). Vision clearance triangles at the intersection must remain unobstructed — no fences, landscaping, or structures over 3 feet in height within the sight-distance triangle. Fence height is typically limited on both street-facing sides.
