Navigating South Florida permits with confidence
South Florida Permitting Guide: What Every Homeowner Needs to Know
Why Permits Matter More in South Florida
South Florida isn't like the rest of the country. Miami-Dade County sits inside the High Velocity Hurricane Zone (HVHZ) — the most stringent building code jurisdiction in the United States. Every permitted project here must meet wind-load, flood elevation, and structural requirements that go far beyond standard national codes. Skipping a permit doesn't just risk a fine — it can invalidate your homeowner's insurance and make your home unsellable.
What Work Requires a Permit in South Florida?
Almost any structural, mechanical, electrical, or plumbing work requires a permit. This includes new construction and additions, roof replacements, window and door replacements (including impact windows), electrical panel upgrades, plumbing relocations, HVAC installations, structural wall removal, pools, decks, patios, fences over a certain height, and solar panel installations. When in doubt, always check — unpermitted work is one of the most common problems we see when clients come to us to fix another contractor's mistakes.
How Long Does Permitting Take in South Florida?
Residential projects in Miami-Dade currently take 4–8 weeks for plan review. Commercial projects run 6–12 weeks. One round of revision comments — which is common — can add 3–6 more weeks. A complete package with proper engineering drawings and product approvals dramatically reduces revision cycles. For new custom homes, plan on 10–16 weeks of permitting. Home additions: 6–10 weeks. Kitchen and bath remodels with structural work: 4–8 weeks. We always build permit timeline buffers into every project schedule.
