Mechanical permit or sub-permit check for heat pump installation or replacement

City of Miami's Easy Permit page lists mechanical permits for like-for-like central AC and heating system replacements, while the City's sub-permit guidance identifies mechanical permits as a trade path for specific parts of a building project. Heat pump installation or replacement in Miami should be checked with the Building Department because the scope can involve mechanical equipment, electrical wiring, roofing or wall penetrations, plumbing or condensate drainage, structural support, or a master permit.
