In 2019, a Treasure Island homeowner and his family sued the city over its short-term rental ordinance. Their argument was not that the city had no right to regulate rentals. It was that the ordinance never defined who counts as a "lessee" or a "holder," which meant a rule aimed at paying guests could, on a literal reading, sweep in a friend staying at the house, a relative watching the place, or a pet sitter checking in more than the code's yearly limit allowed. The case, reported by the Beach Beacon, is a reminder that this ordinance has real edges people have run into, not a tidy set of numbers on a planning map.
That is the part most buyers skip. Someone shopping for a Treasure Island condo with rental income in mind tends to start and stop with the zoning district, treating it as the whole answer. It is only the first of two separate checks, and the second one, sitting inside the condo association's own paperwork, has the power to overrule what the zoning allows.
Two Zones, Two Very Different Ceilings
The City of Treasure Island's Community Development Department publishes the actual mechanism on its short-term rental page, and it works off a different concept than most Florida beach cities. Rather than setting a minimum number of nights per stay, the city counts changes of occupancy, meaning every time a new person or group takes over a residence on a temporary basis.
| Zoning District | Change-of-Occupancy Cap | Typically Found |
|---|---|---|
| RU-75 (single-family) | 2 per year | Canal-front houses, Isle of Capri and Isle of Palms lots |
| RM-15 (multi-family) | 6 per year | Older low-rise buildings set back from the beach strip |
| CG, RFM-30, RFH-50, PR-MU Core, PR-MU Gulf Boulevard | No cap | The Gulf Boulevard resort corridor and condo-hotel buildings |
Cross a zoning line on Treasure Island and the legal ceiling on turnover changes completely. A unit in RU-75 or RM-15 that is publicly advertised for rent, or that exceeds its cap, gets treated by the city as a Tourist Dwelling, a designation the code does not permit in those two districts at all. The five zones without a cap are where condo-hotels and most Gulf-facing investment condos sit, and they are the only places on the island where nightly turnover is not capped by city code.
What a Change of Occupancy Actually Counts
A two-week guest and a two-night guest both register as exactly one change of occupancy. That distinction matters more than it sounds. A buyer running the numbers on a capped RU-75 or RM-15 property cannot simply divide 365 nights by an average stay length to estimate annual turnover potential. The cap is on the number of distinct guest groups, not the number of nights those guests occupy the unit, which means a two-changes-per-year limit is a hard stop no matter how the calendar gets filled.
The Building's Documents Outrank the City's Zoning
Here is the part the zoning map cannot show. Even inside CG, RFM-30, RFH-50, PR-MU Core, or PR-MU Gulf Boulevard, a condominium's own Declaration, Bylaws, and Rules and Regulations can prohibit short-term rentals outright, or restrict them well below whatever the zoning allows. The city's ordinance sets a ceiling. The association's governing documents set the actual floor and ceiling that applies to a specific unit, and Florida law lets associations write those rules independently of what happens at the municipal level.
That means a seller or listing agent saying "this building allows nightly rentals" describes what has been true for them. The Declaration, the Bylaws, and the current Rules and Regulations need to be requested and read before an offer goes in, not discovered afterward.
Condo-Hotels Run on a Separate Set of Rules
Condo-hotels are their own category under the city's code, allowed in any zoning district where a hotel or motel use would be permitted, and exempt from the general prohibition on kitchens in transient accommodations as long as the structure meets specific construction and use criteria. That flexibility comes with a tradeoff: the ordinance caps how many days an owner can occupy their own condo-hotel unit, limiting it to 90 days within any rolling 12-month period. A buyer planning to split time between personal use and rental income in a condo-hotel building needs to check that number against their own plans before assuming the flexibility of the zoning translates into unlimited personal use.
The full text of these provisions sits in the city's zoning code, published through Municode's library for Treasure Island, and it is worth reading directly rather than relying on a secondhand summary, given how the 2019 lawsuit turned on exactly that kind of undefined language.
What the Spread in Closed Sales Actually Shows
Closed sales provide one useful view of Treasure Island's condo market. According to StellarMLS figures for April 2026, nine Treasure Island condominiums and condo-hotels closed that month at a median sale price of $560,000, a median 96.3 percent of list price, and a median of 34 days on market. Closed prices ran from $185,000 for a one-bedroom unit without a Gulf view to $979,000 for a new-build resort condo.
Compare that to the broader condo market the same month. Across the island's full inventory of condos for sale, listed from $199,000 to $4,995,000, the average time on market ran to 119 days, according to Homes.com data for April 2026. Waterfront homes told a similar story, sitting at a median list price of $745,000 with a typical 110 days on market, per Redfin's April 2026 snapshot.
The figures compare different groups and measures: closed condos and condo-hotels are reported by median days on market, while the broader condo inventory is reported by average time on market. They do not show whether zoning or condo documents explain the difference.
Three Registrations Before the First Booking
Once zoning and the condo documents both check out, the compliance work is not finished. The city's own guidance lists what has to be in place before a unit can legally take its first paying guest:
- A City of Treasure Island Local Business Tax Application, filed and paid annually to the city
- Avantio says every Florida vacation rental needs a license from the Florida Department of Business and Professional Regulation
- A Pinellas County Tourist Development Tax account, since the county's 6 percent tax applies to any guest renting for six months or less
The city's short-term rental page also flags a detail that catches owner-occupants off guard: renting out the dwelling, even occasionally, can put a homestead exemption at risk if the owner is not permanently residing there. That is a separate conversation with a tax professional, but it belongs on the list of things to confirm before closing, not after the first booking goes out.
A Practical Order of Operations
Before writing an offer on a Treasure Island unit marketed for rental income, the sequence that avoids the most expensive mistakes looks like this. Pull the zoning district first, using the city's own zoning map, so the change-of-occupancy ceiling is known before a single showing happens. Request the Declaration, Bylaws, and current Rules and Regulations directly from the association, not a summary from the seller's side. If the building is a condo-hotel, check the 90-day owner-occupancy language against personal plans for the unit. Then budget the lead time for the business tax application, the DBPR license, and the county tax account, since none of them happen instantly and a closing date is not the same as a booking-ready date.
Frequently Asked Questions
What exactly counts as a change of occupancy? Any time a new person or group takes over the residence on a temporary basis, regardless of how long they stay. A weekend guest and a month-long tenant each count as one.
If my building sits in a zone with no cap, can the association still say no? Yes. City zoning sets the outer limit of what is legally possible. The condominium's own governing documents can be stricter than that limit, and only those documents determine what a specific unit is actually allowed to do.
I want to use my condo-hotel unit myself part of the year. Is there a limit? Owner occupancy of a condo-hotel unit is capped at 90 days within any consecutive 12-month period under the city's code, a detail worth checking against personal plans before assuming unlimited flexibility comes with the zoning.
Numbers on a zoning map only tell part of the story on Treasure Island, and the gap between what the city allows and what a specific building actually permits is exactly where offers fall apart after the fact.
