Summary
Most residential base districts in Collier County set no maximum building-coverage percentage for the principal home, relying on setbacks instead. Accessory buildings, however, may not cover more than 5 percent of total lot area in any residential district.
Accessory buildings shall not occupy an area greater than five (5) percent of the total lot area in all residential zoning districts, or occupy an area greater than forty (40) percent of any building envelope (i.e., area of lot remaining for building purposes after accounting for required setbacks), whichever is the lesser.
Official source re-checked September 7, 2026: no newer edition of the code had been published (publisher’s edition: Code of Ordinances: Supplement 126 | Land Development Code: Supplement 33).
Full Breakdown
Under LDC Section 4.02.01, Table 1, maximum building coverage is listed as 'None' for the residential base districts (Estates, RSF, RMF, VR, MH), so principal-home footprint is governed by required yard setbacks rather than a fixed coverage percentage. Business Park (BP) is a notable exception at 45 percent. For accessory buildings, LDC Section 4.02.03 B limits them to no more than 5 percent of total lot area in all residential zoning districts, or 40 percent of the buildable area (the lot area remaining after setbacks), whichever is less, without exceeding the overall coverage allowance. Accessory buildings under 500 square feet are allowed if setback and spacing rules are met.
Violations & Fines
Coverage exceeding the accessory limit or the buildable-area cap can be denied at permit review or cited by Code Enforcement, requiring reduction or a variance.
