Structure height in Sunnyvale depends on zone. R-1 homes are capped at about 30 feet or 2 stories; mixed-use and commercial zones permit taller buildings under Title 19.
Height limits are established in SMC Title 19 by zoning district. In R-1 single-family residential the maximum building height is generally 30 feet with a 2-story cap, subject to daylight plane rules that step back upper stories from side property lines. R-2 and R-3 multifamily zones allow 35 to 45 feet depending on density. Commercial, mixed-use, and downtown Specific Plan areas permit taller buildings, often 50 to 85 feet or higher with design review. Accessory structures like sheds are limited to about 8 to 10 feet near property lines. ADUs may be up to 16 to 18 feet (detached) or higher for attached/junior ADUs consistent with state law. Rooftop equipment, antennas, and elevator overruns can extend above the base limit with Planning approval.
