Full Breakdown

040, governs how much of an RS-1 through RM-12 lot can be covered by roofed structures. The rule scales with lot size rather than applying one flat percentage citywide. A site of 7,200 square feet or less carries no maximum lot coverage at all under this table, leaving coverage to be limited instead by setbacks, floor-area, and height standards. Once a lot exceeds 7,200 square feet and runs up to 11,999 square feet, coverage is capped at 35 percent, though an owner can push that to 40 percent if every square foot of coverage above the 35 percent line is single-story only, with no second floor above it.

Lots of 12,000 square feet or larger get the more generous of two figures, 35 percent of the lot or a flat 4,800 square feet, and again any coverage beyond the 35 percent threshold has to stay single-story. 250. Lot coverage is a distinct limit from the maximum floor area ratio and the neighborhood compatibility calculation in the same table, so a project can be within the coverage cap and still exceed the floor-area limit, or vice versa.

Violations & Fines

Building beyond the lot coverage cap is treated the same as any other Zoning Code violation: a structure erected, enlarged, or maintained contrary to Table 2-3 is declared a public nuisance under Section 17.78.060, subject to a Stop Work Order and administrative penalties under Chapters 1.25 and 1.26 of the Municipal Code. Section 17.78.070 makes each day of over-coverage construction a separate offense, and City plan check staff will not issue a Building Permit for a project that exceeds the table's coverage percentage in the first place.

Is there a lot coverage limit on small lots?
