Cupertino limits single-family R1 homes to a maximum of 28 feet and two stories. Zones with an 'i' suffix are restricted to one story not exceeding 18 feet. Height limits are set in Municipal Code Chapter 19.28, with fences capped separately at 6 to 10 feet.
Under Cupertino Municipal Code Chapter 19.28 and Table 19.28.070, principal structures in the R1 Single-Family Residential district may not exceed 28 feet in height and are limited to two stories. R1 zones carrying an 'i' (one-story) designation are limited to a single story not exceeding 18 feet, protecting neighborhood scale and privacy. Second-story development is further constrained by increased setbacks and building-form standards. These building height limits are distinct from fence heights, which Chapter 16.28 caps at 3 feet in front yards, 6 feet in side and rear yards, 8 feet with a permit and neighbor consent, and 10 feet before a Fence Exception applies. Accessory structures must also meet the zone's height standards.
Building above the applicable height limit or story count without an approved exception violates Chapter 19.28 and may require redesign, reduction, or a variance.
