Can I Rent My Backyard Cottage on Airbnb in Florida?

Most Florida cities prohibit ADU rentals under 30 days. City of Miami and City of Sarasota are the main exceptions where short-term rental licensing is available. If you're planning to build an ADU for Airbnb income, your city's STR rules may eliminate that strategy before you break ground — here's the complete 2026 breakdown.

The Florida STR Patchwork: Why City Rules Vary So Much

Florida has a fragmented short-term rental regulatory environment. Florida Statute 509 establishes statewide vacation rental licensing through the DBPR (Department of Business and Professional Regulation), but it does not preempt local minimum-stay requirements adopted before 2011. This grandfathering clause means cities that had STR restrictions in place before June 2011 can keep and enforce them — and most major Florida cities did.

The practical result: whether you can operate a short-term ADU rental in Florida is entirely city-specific, and sometimes neighborhood-specific within the same city. The table below reflects 2026 rules from each city's current zoning code and ordinances.

City-by-City STR Rules for ADUs (2026)

City	STR Allowed?	Minimum Stay	License Required	Key Condition
Miami	Yes	None stated	Certificate of Use + annual fee $750+	Availability capped by neighborhood — waitlists exist
Sarasota City	Yes	7 days	Vacation Rental Certificate of Registration	City only — Sarasota County bans STR under 30 days
Jacksonville	Verify locally	None stated	Local license may be required	No citywide prohibition — confirm by address
Gainesville	Yes	None stated	DBPR state license	No citywide prohibition; STR allowed with state license
Tallahassee	Yes	None stated	DBPR state license	Both STR and long-term rental permitted
Tampa	Effectively no	7 days minimum	Special Use permit (annual renewal)	7-day minimum blocks Airbnb-style use; annual renewal
Orlando	No	30 days	N/A — prohibited	Prohibited in all residential zones
Fort Lauderdale	No	30 days	Annual Certificate of Use for any rental	Prohibited; annual COU required for 30+ day rentals
Clearwater	No	31 days	N/A — prohibited	31-day minimum enforced strictly
St. Petersburg	No	30 days	N/A — prohibited	30-day minimum framework in residential zones
West Palm Beach	No	183 days	N/A — effectively prohibited	183-day minimum (6 months + 1 day)
Miami Beach	Mostly no	Varies by zone	STR permits capped — largely unavailable	Separate city from Miami; much more restrictive

Miami: The Most Open Major Market for ADU Short-Term Rentals

The City of Miami (distinct from Miami Beach, which is a separate municipality) currently permits short-term rentals with a Certificate of Use (COU) and annual registration. Requirements include a $750+ annual fee, property inspection, and for some zones, a community meeting notification process. Miami's STR market is genuinely active year-round — international tourism, conference traffic, and the Brickell financial district create real demand for short-stay accommodations.

Important caveats: STR license availability is capped by neighborhood. Wynwood, Brickell-adjacent areas, and Little Havana have wait-listed license pools. Confirm that a new license is available for your specific address at miamigov.com before budgeting for STR income. Miami 21 transect zone eligibility for the ADU itself is a separate gate — confirm T3-O, T4, T5, or T6 zoning first.

Tampa: The 7-Day Rule and Annual Renewal Risk

Tampa's ADU program is concentrated in 8 eligible neighborhoods under RS-50, SH-RS, and RS-60 zoning. Short-term rentals under 7 days are prohibited. The 7-day minimum dramatically limits Airbnb-style use — Tampa's leisure tourism market is not built around week-long residential stays.

More significantly, Tampa's ADU Special Use permits require annual renewal. Any violation of rental rules — including operating an unpermitted STR — can result in permit revocation, ending your legal right to operate the ADU at all. The annual renewal review gives the city an ongoing mechanism to audit compliance. Tampa ADUs work well as long-term rental units ($1,200–$2,200/month) but should not be planned as STR income properties. Contact Tampa Zoning at TampaZoning@tampagov.net or (813) 274-3100.

Sarasota: The Critical City vs. County Split

Sarasota is the most important jurisdiction-split case in Florida for STR planning. The two jurisdictions have opposite STR rules:

• City of Sarasota: STR allowed with a Vacation Rental Certificate of Registration and 7-day minimum stay. Owner-occupancy not required. ADU sizes — the city has no hard cap in current code (confirm with planning). Rental income $1,400–$2,500/month with potential upside on a nightly basis for arts and culture tourism.
• Sarasota County (unincorporated): STR banned under 30 days in all single-family residential zones. Owner-occupancy required. ADU max 500 sq ft. If your address is in unincorporated Sarasota County — even if it feels like "Sarasota" — the county rules apply, not the city's.

Determine your jurisdiction at the Sarasota County Property Appraiser website (scpafl.org) before any STR planning. Look for "City of Sarasota" vs. "Sarasota County" in the jurisdiction field of your parcel record.

What to Do If You Want STR Income from an ADU

If short-term rental income is a significant part of your ADU investment thesis, follow this sequence before committing to any market:

1. Confirm your city's current STR minimum stay rule (the table above provides 2026 data — verify with the city directly)
2. In Miami: confirm that a new STR Certificate of Use is available for your address — call (305) 416-1100
3. In Sarasota: confirm you are in City of Sarasota jurisdiction, not unincorporated county
4. Check your HOA or deed restrictions for STR language — private covenants override city zoning
5. Run the income math: how much does nightly STR income improve vs. monthly long-term rent? Divide by the additional management cost and license fees. In many Florida markets, the 30-day minimum effectively makes the comparison moot.

Frequently Asked Questions

Can I use my Florida ADU as an Airbnb?

Only in specific cities. City of Miami (with Certificate of Use), City of Sarasota (with Vacation Rental Certificate, 7-day minimum), Gainesville, Tallahassee, and Jacksonville currently permit ADU short-term rentals. Tampa, Orlando, Fort Lauderdale, Clearwater, St. Petersburg, and West Palm Beach all impose minimum stays of 7–183 days that effectively prohibit Airbnb-style use. Always verify with your city's zoning department before purchasing or building.

What happens if I run an unpermitted Airbnb in a Florida city that bans it?

Enforcement varies by city. In Tampa, STR violations can result in revocation of your ADU's Special Use permit — ending the legal right to operate the ADU at all. In Fort Lauderdale, operating without an annual Certificate of Use is a code violation subject to fines. Most cities issue warning notices before escalating, but enforcement has increased significantly since 2023. Florida's short-term rental complaint hotlines are actively monitored.

Does Florida state law protect short-term rentals?

Partially. Florida Statute 509 establishes DBPR licensing for vacation rentals, and a 2011 state law limited new STR bans after June 1, 2011. But cities that had restrictions in place before that date can keep and enforce them. Most major Florida city STR minimums either predated 2011 or were adopted through the vacation rental license framework — making them enforceable. State law does not override the city-level minimum stay rules listed in the table above.
