Full Breakdown
Oakland's citywide "lot coverage" definition, in the Planning Code's definitions section, means the total land area covered by all structures on a lot measured from the outside of exterior walls and supporting columns, including projections, but excluding certain low decks, porches and balconies. The actual numeric coverage cap is set zone by zone in each residential chapter's development-standards table, not by a single citywide percentage. 04, which pairs Floor Area Ratio and lot coverage limits to lot size: lots under 5,000 square feet and lots between 5,000 and 12,000 square feet are both capped at 40% lot coverage, lots between 12,000 and 25,000 square feet drop to 30%, lots between 25,000 and 43,560 square feet drop to 20%, and lots above 43,560 square feet (one acre) are capped at 15%.

Exceeding the applicable coverage figure requires either redesign or a variance.
Violations & Fines
Building beyond the maximum lot coverage percentage set in the applicable zone's development-standards table without an approved variance is a zoning infraction under Planning Code Section 17.152.030, punishable by a fine to the state maximum, with each day of the violation a separate offense and misdemeanor exposure after a third conviction in a year; the city can also require removal or reduction of the offending structure.
