Fremont generally limits lot coverage in R-1 zones to 40 percent for the primary structure, with total coverage including accessory buildings capped at 50 percent.
Lot coverage in Fremont R-1 zones is typically capped at 40 percent for the main building footprint, with total coverage (main plus accessory structures) up to 50 percent depending on the specific zone. Pools, patios, driveways, and other impervious surfaces may count toward coverage depending on whether they are at-grade or structural. Floor Area Ratio (FAR) limits further constrain building size — typical R-1 FAR is 0.45 to 0.50. ADUs up to 1,200 square feet may be exempt from maximum FAR and lot coverage under state law (Government Code 65852.2). Hillside parcels in the Hillside Combining District have stricter coverage to limit grading and preserve natural terrain.
