Summary
In the unincorporated Florida Keys (Monroe County), Land Development Code § 114-13(h) requires a building permit from the county building department before any fence or wall goes up, in order to protect public health, safety and welfare under Section 114-13. On Big Pine Key and No Name Key, the permit must also meet the requirements of the county's Habitat Conservation Plan and Incidental Take Permit (HCP/ITP).
It is the purpose of this section to regulate fences and walls in order to protect the public health, safety and welfare. ... (h)Required permit. All fences shall be constructed pursuant to a building permit issued by the county building department and, if applicable, according to the requirements of the HCP/ITP.
Full Breakdown
Every fence and wall built in the unincorporated Keys needs a building permit under Section 114-13(h), issued by the county building department, before construction starts. That permit sits alongside the substantive standards in the rest of Section 114-13: height limits that generally cap fences at six feet but drop to three or four feet near roads, driveways and front-yard setbacks; a rule that fencing may run along the property line as long as it does not block fire and emergency access, cut through wetlands, or clear native vegetation from a required bufferyard; and a maintenance duty that keeps every fence in good repair once built.
S. Fish and Wildlife Service. Limited clearing to install a fence or gate is allowed only if it avoids scenic corridors under Section 114-125, does not remove the minimum buffer required by Section 114-124, and leaves existing native hardwood and pineland hammock trees in place. The Planning Director approves construction details and materials for any fence other than chain-link that is used to reach the taller height allowances elsewhere in the section.
Violations & Fines
Building a fence or wall without the required permit is a violation the county building department and Code Compliance can pursue, and on Big Pine Key or No Name Key a fence that skips the HCP/ITP standards, such as required Key Deer setbacks or wetland clearance, adds a second violation even if a permit was issued for something else. An unpermitted or noncompliant fence can be ordered corrected or removed.
