Full Breakdown
" The formula benefits smaller lots -- a lot where 40% works out to less than 2,500 square feet still gets the flat 2,500-square-foot allowance -- while the 50% ceiling stops larger lots from building an outsized footprint. 020's citywide definitions chapter defines "lot coverage" as the percentage of a lot covered by all buildings or structures, including porches, breezeways and patio roofs whether open or fully roofed, but excluding fences, walls, hedges used as fences, uncovered porches or patios under 30 inches high, and swimming pools; a residential eave overhang of two feet or less is also excluded, but if the overhang exceeds two feet the entire overhang counts toward coverage.
220) imposes no lot coverage limit at all. Height (35 feet in R-1) and floor-area-ratio limits under the general plan apply on top of the coverage cap, so a project can be capped by whichever standard is more restrictive on a given lot.
Violations & Fines
Exceeding the R-1 zone's lot coverage cap is a zoning code violation. The city's Community Development Department reviews coverage as part of building permit plan check, and a project that exceeds 40%/2,500-square-foot or the 50% hard ceiling will be denied permit issuance or, if built without correction, referred to code enforcement for a correction order; property owners can seek relief only through a variance application, not administrative waiver.
