Monroe County, FL Solar Energy: Panel Permits (2026)

Monroe County's Land Development Code exempts solar collection systems on single-family residences from its adequate-facilities concurrency review under Section 114-2(a)(6)(m). That review, built around the county's Area of Critical State Concern status and the Upper, Middle, and Lower Keys service areas, normally requires a facilities impact report demonstrating that potable water, sewer, drainage, and road capacity can absorb a project; the solar exemption means a homeowner does not need that report just to add rooftop panels. That exemption does not eliminate the building permit itself.

Chapter 6's general permit table at Section 6-100(a) still reaches solar work as construction in the electrical, mechanical, and plumbing trades, and the installer needs a Monroe County certificate of competency under Section 6-198's solar products specialty classification. That license lets a solar contractor handle the water heating or pool heating system, the branch circuit and controller wiring on the load side of the service disconnect, and roofing work directly tied to mounting the panels, but only within 18 inches of each roof penetration or attachment point, performed to National Roofing Contractors Association practices; wiring changes upstream of the service disconnect require a separately licensed electrical contractor.

Because the panels themselves sit on a roof governed by the Keys' windload design standards under Section 6-26, the Building Official reviews the mounting and attachment details for Florida Building Code compliance as part of permit issuance, even though the concurrency step is waived.
