Santa Clarita, CA Building Setbacks & Zoning: Lot Coverage Limits (2026)

Section 17.03.030(F) defines lot coverage citywide as the ratio of the total footprint area of all structures on a lot to the net lot area, expressed as a percentage carried to the hundredths place. Covered area includes the footprints of primary and accessory structures such as garages, carports, covered patios, and roofed porches, plus unenclosed and unroofed decks, uncovered patio slabs, porches, landings, balconies, stairways, the first floor of atriums and lobby areas, and any eave or roof overhang that projects more than two-and-one-half feet from the building wall. Excluded are uncovered walkways, driveways, landscaping, smaller overhangs of two-and-one-half feet or less, and swimming pools or hot tubs that are not enclosed in a roofed structure or deck.

The actual percentage cap is set zone by zone in Chapter 17.34. The Community Commercial (CC) zone caps lot coverage at 80 percent under Section 17.34.010; the Neighborhood Commercial (CN) zone caps it at 75 percent under Section 17.34.020; and the Regional Commercial (CR) zone allows up to 90 percent without a conditional use permit under Section 17.34.030, the same 90 percent ceiling used in the City's industrial and business-park zones. By contrast, the residential zone tables in Chapter 17.33 set no separate maximum lot coverage figure; single-family and multi-family residential lots are instead controlled through the front, side, and rear yard setbacks and height limits listed for each residential zone.
