One of the most common questions we hear from Miami property owners and contractors is “How long is this going to take?” Here is an honest breakdown of building permit timelines in Miami-Dade County in 2026.
Simple Mechanical, Electrical, Plumbing Permits
Standalone trade permits — like AC change-outs, water heater replacements, electrical panel upgrades, or simple plumbing repairs — typically take 1 to 5 business days in most Miami-Dade municipalities. These are often approved over-the-counter or through online express review systems.
Window and Door Replacement Permits
Window and door replacement permits in Miami-Dade typically take 2 to 4 weeks. Cities verify each product against Florida Product Approval (FPA) numbers and confirm HVHZ compliance. This process is straightforward when documentation is complete from the start.
Roof Replacement Permits
Residential roof replacement permits in Miami-Dade typically take 2 to 4 weeks. Cities verify the roofing system, underlayment, and fastening schedules meet HVHZ requirements. Tile re-roofs sometimes require additional structural review.
Kitchen and Bathroom Remodel Permits
Renovation permits involving electrical, plumbing, and structural changes typically take 3 to 6 weeks. Larger gut renovations with multi-trade coordination can run 6 to 10 weeks depending on city.
Room Additions and New Construction
Major additions and new home construction typically take 8 to 16 weeks depending on size and complexity. Cities review structural engineering, HVAC sizing, electrical load calculations, plumbing fixture counts, and energy code compliance.
Commercial Permits
Commercial permits in Miami-Dade typically take 4 to 12 weeks. Tenant improvements run on the faster end. Restaurant buildouts and high-rise renovations are typically longer due to additional fire, ADA, and life safety reviews.
What Slows Permits Down
The biggest delays come from incomplete application packages (forcing rejection and resubmission), plan review corrections (each cycle adds 1-2 weeks), missing or expired Florida Product Approval documentation, and submitting to the wrong jurisdiction.
