The Florida Fire Prevention Code mandates compliance with the NFPA code family in new construction and existing buildings. NFPA-1221, Standards for Installation, Maintenance, and Use of Emergency Services Communications systems, Mandates in-building emergency responder radio signal minimum coverage requirements.  Two types of building areas are defined: critical areas and general building areas. Critical areas include emergency command centers, fire pump rooms, exit stairs, exit passageways, elevator lobbies, standpipe cabinets and other areas deemed critical by the AHJ. Critical areas must have 99% coverage, while general building areas must have 90% coverage.

According to the NFPA definition, an AHJ, or authority having jurisdiction,  is an organization, office, or individual responsible for enforcing requirements of code or standard, or for approving equipment, materials, an installation, or a procedure. In the State of Florida, the AHJ can be a local fire department or FCC license holder.
