Summary
In Jupiter's Residential, Single-Family District (R-1), buildings and structures on a lot cannot cover more than 35 percent of the lot area. The cap sits in the same area and dimension table that sets the district's minimum lot size, setbacks and height limit.
In the Residential, Single-Family District (R-1) on each lot that is used hereafter, and on each lot upon which a building or structure hereafter is erected or enlarged and maintained, the following regulations shall be observed: Dimension Measurement ... Lot coverage (maximum) 35 percent
Full Breakdown
Sec. 27-1324 lays out the area and dimension regulations that apply to every lot in the R-1 district that is used, built on, or has a structure enlarged after the ordinance took effect. Alongside the 35 percent lot coverage maximum, the same table sets a 10,000-square-foot minimum lot area, a 75-foot minimum lot width, and a 100-foot minimum lot depth, plus a 1,200-square-foot minimum dwelling floor area. A carve-out applies to substandard lots of record: a detached single-family residence on a lot platted in Palm Beach County on or before July 29, 1969 can compute its minimum floor area at 1,200 square feet including porch, carport and garage, provided the home still has at least 1,000 square feet of actual living area.
The table also cross-references division 15 of article XI for exceptions to development regulations, meaning certain accessory features can be excused from strict counting against the coverage cap under separate, narrower rules rather than blowing through the 35 percent limit outright. Because the R-1 district covers most of Jupiter's older single-family neighborhoods, this coverage cap is the baseline a homeowner planning an addition, garage or pool deck has to design around before applying for a building permit.
Violations & Fines
Building or enlarging a structure that pushes total lot coverage past 35 percent without an approved exception is a zoning violation enforced by the building division at permit review, and if discovered after construction, the matter is referred to the code enforcement board or a special magistrate under Sec. 8-40(a) for fines up to $1,000 per day for a first violation and $5,000 per day for a repeat violation until the property is brought into compliance.
