Building, mechanical, or exemption check for insulation and air-sealing work
City of Miami's work-exempt page lists specific building, electrical, mechanical, gas, and plumbing work that does not require a permit, and says exempt work still must meet building code, safety, zoning, and flood rules and that applicants should check with the Building Department when in doubt. Because insulation and air-sealing are not listed as a broad no-permit category there, and because related duct, HVAC, electrical, roof, exterior wall, or remodeling work can change the permit path, Miami insulation or air-sealing projects should be confirmed before work begins.
