A. Exceptions. In calculating the percentage of lot coverage for the purpose of applying the regulations of this Zoning Code, the features of a structure as hereafter set forth shall not be included as coverage:
1. Cornices, canopies, eaves or other projections which do not increase the volume of space enclosed by the building provided that any portion of such projections extending more than two feet from the building shall be included as coverage;
Official source re-checked September 7, 2026: no newer edition of the code had been published (publisher’s edition: rev 4967405; v8 updated 2026-07-06).
Full Breakdown
The coverage percentage is calculated against the total lot area, but Subsection A excludes several building features from the count: cornices, canopies, eaves and similar projections that do not enclose additional space (unless they extend more than two feet from the building, in which case the excess counts), fire escapes up to three and a half feet, an uncovered stair and landing that does not rise above a ground-floor entrance, and bay windows, balconies or chimneys projecting no more than two feet, provided they do not occupy more than one-third of an interior-side-facing wall or two-thirds of a street- or rear-facing wall.
Subsection B gives covered porches a further break: only half of a Covered Porch's roofed area counts toward coverage. These exclusions matter most on the single-family RS/RD lots capped at 50 percent, where a wraparound porch or bay window can be the difference between a compliant addition and a coverage violation requiring redesign or a variance. 376's additional setback and lot coverage rules for that district specifically.
Violations & Fines
Exceeding the applicable lot coverage percentage without qualifying for one of the Section 2.04.328(A)-(B) exclusions is a Zoning Code violation under Section 5.24.112: land-use and development violations are chargeable as misdemeanors (up to $1,000 fine and up to one year in County Jail), reducible to an infraction at the Zoning Enforcement Official's discretion, with each day of over-coverage a separate violation. The City can also issue a Notice to Abate under Section 5.24.116 and pursue an administrative hearing before ordering correction of an over-built structure.
