Fremont limits single-family homes to 30 feet or 2 stories in most R-1 zones, with hillside overlay districts imposing stricter limits to protect ridgelines.
Fremont Municipal Code Title 18 caps building heights in R-1 zones at 30 feet or 2 stories, whichever is less, measured from finished grade to the highest point of the roof (excluding chimneys and antennae). Accessory structures like sheds are limited to 15 feet. The Hill Area Initiative and Hillside Combining District (overlay zoning adopted after Measure T) impose additional restrictions protecting ridgelines, view corridors, and open space in the Mission Peak, Niles Canyon, and eastern hills. Multi-family zones permit greater heights. ADUs may be up to 25 feet if detached or matching the primary dwelling per state law. Exceeding height limits requires a variance or planned district approval.
