Key West FAQ
Common questions about permits, flood compliance, and construction in Key West.
What makes Key West the most challenging coastal flood compliance environment in Florida?
Key West combines extreme flood vulnerability — 92% of properties in Zone VE or AE at an average elevation of 4 feet — with a major historic district, strict height limits, hurricane-impact window requirements, and Monroe County's ROGO (Rate of Growth Ordinance) development controls. MKC navigates all of these simultaneously for every project.
Does MKC handle Monroe County and City of Key West permits?
Yes. MKC manages permits through both the City of Key West's Building Department and Monroe County Building Department depending on project location. Key West has its own permit jurisdiction separate from unincorporated Monroe County.
What FEMA compliance is required for Key West properties?
Key West is predominantly Zone VE — the highest-risk FEMA designation. All construction must meet strict coastal standards: elevated on open pile or column foundations, breakaway walls below BFE, no fill under structures, and wave action engineering. The city's low elevation means BFE is often 10–14 feet above existing grade.
How does Key West's historic district affect construction permits?
Key West has one of Florida's most protected historic districts, with the Old Town National Register Historic District covering much of the island. Exterior changes require Key West Historic Architectural Review Commission (HARC) approval. MKC coordinates HARC review alongside FEMA compliance and building permits — a complex multi-agency process.
Can MKC handle after-the-fact permits in Key West?
Yes. MKC handles ATF permit resolution in Key West and Monroe County — a common need given the age of much of Key West's housing stock and the complexity of compliance requirements that have led to unpermitted work over the decades.
