Full Breakdown
The Planning and Neighborhood Services Division measures lot coverage as the footprint of every building on a parcel against the parcel's total area, and the ceiling changes with zoning district rather than applying citywide. 04(F)(3) caps coverage at 50% regardless of which of those five minimum lot sizes, from 40,000 down to 6,000 square feet, applies to a given lot. 05(F)(4). 03(F)(3). Coverage is calculated on the building footprint only; it sits alongside, and is separate from, the district's minimum yard setbacks, which independently restrict how close a structure can sit to a property line. 04, not a simple building permit.
Violations & Fines
Exceeding the lot coverage cap without a variance or rezoning is a zoning code violation under § 154-999: a class 1 misdemeanor punishable by a fine up to $1,000, up to ten days in jail, or both. Each day an over-covered structure remains in place counts as a separate offense, and the Building Safety Division can withhold a certificate of occupancy or a permit renewal until the excess coverage is removed or a variance is granted.
