Some RestrictionsCollier County LDC 5.03.02 H.1
Whenever a nonresidential development lies contiguous to or opposite a residentially zoned district, a masonry wall, concrete or pre-fabricated concrete wall and/or fence shall be constructed on the nonresidential property. If located on a contiguous property, then height shall be 6 feet to 8 feet and placement shall be no less than 6 feet from the residentially zoned district.
Fence Permit Requirements
Fences and walls are permitted uses in every zoning district, but a Collier County building permit (Fence/Wall application, PRFW) is generally required before installation. Effective July 1, 2026, Florida HB 803 exempts single-family work under $7,500, except in flood hazard areas.

Some RestrictionsCollier County LDC 5.03.02 A
Fences or walls shall be permitted principal uses in all districts, subject to the restrictions set forth in this section, unless specifically exempted; however, a fence or wall shall not, in any way, constitute a use or structure, which permits, requires, and/or provides for any accessory uses and/or structures.
Neighbor Fence Rules
A fence may sit on the lot line, but no part (including the footing) may cross onto a neighbor's property or right-of-way. The finished side must face the adjoining lot, though the county can waive that if the neighbor already has a fence or hedge.
