Full Breakdown
06's Property Development Standards table sets Max. Lot Coverage (%) at 50 for the RL Low Density, RM Medium Density, RMH-A Small Lot Subdistrict, RMH Medium High Density, and RH High Density Residential Districts, and 75 for the RMP Residential Manufactured Home Park District. The percentage is measured against net lot area, defined in Section 203 as the horizontal area within the property lines exclusive of rights-of-way or easements that prohibit surface use for anything but vehicular access. What counts toward the 50% or 75% cap is spelled out in the same Section 203 definition of 'Coverage, Lot or Site': roofs, balconies, fireplaces, architectural projections or overhangs extending more than two and one-half feet from a wall, decks more than 42 inches above grade, and stairs, plus any building projection into a required yard or court that contains habitable floor area.

Violations & Fines
Plans that exceed the district's lot-coverage percentage are rejected at building-permit plan check and cannot receive a permit until coverage is reduced or a Section 241.22 waiver, capped at a 10% deviation, is approved by the Director. Construction completed without an approved permit is treated by the Community Development Department as an unpermitted structure, which can require removal of the offending roof, deck, or projection and correction of the plans before any certificate of occupancy issues.
