Summary
Hialeah caps building footprint at 43 percent of lot area in the R-Z residential zero lot line district under Code Sec. 98-830, the only zoning division in the code that states a lot-coverage percentage this directly. The cap rises to 45 percent when the extra footprint is used for a utility room, and small accessory features are excluded from the calculation entirely.
Sec. 98-830. - Maximum lot coverage. In the R-Z residential zero lot line district, the total lot coverage permitted for all buildings on each lot shall not exceed 43 percent of the lot area. However, lot coverage can be increased to 45 percent where utility rooms are provided.
Full Breakdown
The R-Z residential zero lot line district is Hialeah's zero-lot-line product, built for attached and semi-attached homes on small parcels: Sec. 98-827 sets the minimum lot at 3,400 square feet with a 40-foot width and 85-foot depth. Sec. 98-830 then draws the line on how much of that small lot can actually be covered by structure, capping total lot coverage for all buildings at 43 percent of the lot area. The code allows a two-point bump to 45 percent specifically where the added square footage houses a utility room, recognizing that mechanical space eats into an already tight lot.
Sec. 98-828(5)(d) reinforces the cap by directing that accessory uses, patios, pools, wood decks, garden features and small prefabricated storage sheds placed in the five-foot perimeter setback, are not counted toward the maximum lot coverage figure at all, so a homeowner can add those amenities without eating into the 43/45 percent budget for the house itself. The setback structure around the cap is tight: dwelling units sit on a zero setback along one interior side line, ten feet one inch off the other side line, 21 feet off the front line and 15 feet off the rear line.
Sec. 98-831 lets an owner exceed the front and rear setback by up to 25 percent, or exceed the maximum lot coverage requirement by up to 50 percent of the lot area, through a waiver-of-plat process recorded with the county rather than a full rezoning.
Violations & Fines
A site plan or building permit application that shows footprint above 43 percent (or 45 percent with a qualifying utility room) will be rejected by the building department; construction that proceeds past the cap without a recorded waiver of plat is subject to a stop-work order and can be required to be reduced to bring the lot back into compliance.
