Summary
West Covina caps total building coverage and floor area on R-A and R-1 lots using a sliding formula in Table 2-4: 50 percent of net lot area on lots of 5,000 square feet or less, tapering to smaller percentage increments as lots get larger, with a conditional use permit required above 10,000 square feet of floor area.
(b)Building coverage.(1)The maximum building coverage and floor area of all structures in the R-A and R-1 zones shall not exceed the standards set forth in Table 2-4. Table 2-4 Allowable Building Coverage and Floor Area Lot Size / Allowable Total Building Coverage and Floor Area: 5,000 square feet or less: 50 percent of net lot area; 5,001 to 6,000 square feet: 2,500 square feet plus 30 percent of lot area over 5,000 square feet; 6,001 to 7,500 square feet: 2,800 square feet plus 20 percent of lot area over 6,000 square feet; 7,501 to 10,000 square feet: 3,100 square feet plus 20 percent of lot area over 7,500 square feet; 10,000 square feet or more: 3,600 square feet plus 20 percent of lot area over 10,000 square feet. (i) Review thresholds for large houses. A conditional use permit (CUP) shall be required for any project resulting in a total floor area above 10,000 square feet.

Full Breakdown
Section 26-46(b) sets the coverage and floor area ceiling for R-A and R-1 zoned lots through Table 2-4. Lots of 5,000 square feet or less may cover up to 50 percent of net lot area with buildings and floor area combined. Above that, the formula shifts to a fixed base plus a percentage of the excess: 2,500 square feet plus 30 percent of lot area over 5,000 square feet for lots between 5,001 and 6,000 square feet; 2,800 square feet plus 20 percent of the excess over 6,000 square feet for lots up to 7,500 square feet; 3,100 square feet plus 20 percent of the excess over 7,500 square feet up to 10,000 square feet; and 3,600 square feet plus 20 percent of the excess over 10,000 square feet for anything larger.
Any project that would push total floor area above 10,000 square feet needs a conditional use permit, and that CUP requirement only kicks in on lots large enough for the table to allow 10,000 square feet or more in the first place. Section 26-64 separately defines how lot coverage is measured: the percentage of site area covered by structures, calculated by dividing horizontal roofed area by total lot area within the property boundaries; underground parking, parking structures and semi-covered features like trellis patio covers do not count toward the cap.
A related rule at Section 26-46(c) also limits front-yard pavement and driveway coverage, requiring landscaping in the remaining open front yard area. Two-story volume space with a ceiling or top-plate height over 12 feet counts as two stories for floor-area purposes, though sloped roofs with a 16-foot-or-less ridge and 12-foot-or-less wall height are exempt from that bump.
Violations & Fines
Building beyond the Table 2-4 coverage and floor area cap without an approved conditional use permit is a Development Code violation, enforced through the city's standard code enforcement and administrative citation process; a project that exceeds the allowed square footage can be red-tagged or denied a certificate of occupancy until it is brought into compliance or a variance is obtained. Because lot coverage is calculated on net lot area after required street or alley dedications, a project that miscounts dedicated area to inflate its buildable footprint is treated the same as an outright coverage overage.
