Frequently Asked Questions
Can I build an ADU (Carriage House) on my Miami property?
Yes. Florida HB 1339 (2024) requires Miami to permit ADUs by-right without owner-occupancy requirements. In T3 (Sub-Urban) zones — Miami's primary single-family transect — you can build a Carriage House in the rear of your lot. Miami 21 regulates size, height, and setbacks. Impact fees are capped by state law. The permit process is ministerial (no discretionary review) for ADUs meeting objective standards.
What zoning system does Miami use?
Miami uses a form-based code called Miami 21, adopted in 2009. Instead of traditional use-based zoning, Miami 21 organizes the city into Transect Zones based on urban character — from T1 (Natural) through T6 (Urban Core). The code regulates building form, frontage types, street relationships, and massing rather than just permitted uses. Residential uses in T3 (Sub-Urban) are primarily single-family; T4 through T6 allow increasingly dense multifamily.
Are Airbnb and vacation rentals allowed in Miami?
Yes, with licenses. A Florida DBPR (Department of Business and Professional Regulation) Vacation Rental License is required statewide. Miami has additional local requirements. Miami-Dade County also regulates vacation rentals. Miami has some grandfathered STR restrictions from pre-2011 ordinances. All rentals must pay 13% Miami-Dade Tourist Development Tax. Platforms like Airbnb and VRBO collect and remit applicable taxes.
What are the hurricane wind requirements for building in Miami?
Miami-Dade County is in a High-Velocity Hurricane Zone (HVHZ) — the most stringent wind resistance requirements in the US. All construction must comply with Florida Building Code HVHZ provisions. Roofing products require Miami-Dade Notice of Acceptance (NOA) testing approval. Impact-resistant windows and doors required in new construction and substantial improvements. These requirements increase construction costs but provide significant protection.
Is my Miami property in a flood zone?
Miami-Dade County has extensive FEMA-mapped Special Flood Hazard Areas (SFHAs) due to low elevation and coastal location. Many properties are in AE or VE flood zones requiring flood insurance for federally-backed mortgages. Check the FEMA Flood Map Service Center (msc.fema.gov) for your specific parcel. New construction must meet Base Flood Elevation plus freeboard requirements. Miami is actively addressing sea-level rise through infrastructure investments.
How do I find my property's Transect Zone in Miami?
Use the Miami 21 Interactive Map at gis.miamigov.com/Miami21/. Enter your address to find your Transect Zone designation (T3, T4, T5, T6, or District zones). The map shows allowed uses, building form standards, setbacks, and height limits for your property. Miami 21 is the primary zoning document — you can access the full code at the city's planning department website.
Do I need a permit to operate a home business in Miami?
Yes. A Certificate of Use (Home Occupation) is required for operating a business from a residence in Miami. The fee is approximately $75–$200. Restrictions include no on-site clients or customers, no employees who are not residents, no external signage, and business use limited to 20% of floor area. Cottage food businesses under Florida's Cottage Food Law are exempt from local business permits but sales are capped at $250,000 annually.
