A lot of buyers come to Siesta Key with a number in their head. They've done some research — maybe looked at projected rental income on Airbnb's estimator or a neighboring listing's claimed gross — and they've built that income into their purchase calculus. The property pencils out, the lifestyle makes sense, and the timing feels right.
Then one of two things happens. Either they close, start the rental process, and discover their condo building doesn't allow short-term rentals. Or they find out the licensing and tax obligations are more involved than they expected.
Neither situation is a disaster if you know about it before you make an offer. Both are very expensive if you find out after.
Here's what actually governs vacation rentals on Siesta Key — and what to check before you commit to a property you're counting on for income.
The Three Layers of Regulation
Short-term rentals on Siesta Key operate under three overlapping layers of rules. They stack on top of each other, and the most restrictive one wins.
State law (Florida DBPR). Florida defines a "vacation rental" as any unit rented for periods of less than 30 days or 1 calendar month more than three times in a calendar year. If your property meets that definition, you need a Vacation Rental License from the Florida Department of Business and Professional Regulation before you collect your first payment. For condos, the applicable license type is the Vacation Rental Condominium license. Operating without it is a violation that can result in fines and affect your ability to renew.
County rules (Sarasota County). Sarasota County requires a Business Tax Receipt (BTR) for vacation rental operations — essentially a local business registration. You also need to be registered to collect and remit the 5% Sarasota County Tourist Development Tax (TDT) on gross rental revenue. For bookings made through Airbnb or VRBO, those platforms collect and remit the TDT on your behalf for most transactions. For direct bookings outside those platforms, you handle it yourself.
Your condo association. This is where buyers get surprised most often. A condo association's declaration of condominium and rules can restrict short-term rentals more severely than state or county law — and in Florida, that's legal. The county can allow 7-night minimums. The state doesn't care. But if your building's declaration requires a 30-day or 90-day minimum stay, that's what controls. No workaround exists.
Many Siesta Key condo buildings have minimum rental periods of 30, 60, or 90 days — and some prohibit short-term rentals entirely. The condo documents are the place to start, not the county website.
The Tax Picture
Vacation rental revenue in Sarasota County is subject to two taxes collected from the guest as part of the rental rate:
- Florida state sales tax: 6%
- Sarasota County Tourist Development Tax: 5%
- Combined: 11% on gross rental revenue
If you list on Airbnb or VRBO, both platforms automatically collect and remit these taxes for bookings made through their systems. This covers the vast majority of STR transactions and significantly simplifies compliance. For bookings you take directly — through your own website, a property manager's direct booking system, or any channel outside the major platforms — you're responsible for collecting the 11% from the guest and remitting it to the Florida Department of Revenue (state tax) and Sarasota County (TDT) on the required schedule.
You'll also have federal income tax obligations on rental income, and the IRS has specific rules around the 14-day rule for vacation homes used personally — worth a conversation with a tax advisor before you finalize your purchase structure.
What to Ask Before You Make an Offer
If rental income is part of why this property makes sense for you, these are the questions to get answered in due diligence — not after closing.
What does the condo declaration say about minimum rental periods? Request the full Declaration of Condominium and the current Rules & Regulations. The rental restriction language is usually in both. The declaration is the controlling document; rules can be amended more easily and may be more or less restrictive than what the declaration originally required. Both matter.
Has the association ever discussed changing the rental policy? Request the last 24 months of HOA board meeting minutes and look for any discussions about tightening rental restrictions. A building that currently allows 7-night minimums but has been debating a move to 30-day minimums is a very different investment than one where the policy has been stable for years.
What is the actual rental history of this unit? If the seller has been renting the property, request documented rental income history. Estimates from Airbnb's calculator are based on market averages; actual performance of this specific unit in this specific building tells you far more. Ask whether the unit is currently listed anywhere, what the occupancy rate has been, and what gross revenue looks like in a typical year.
Does the building have an on-site management or rental program? Some Siesta Key condo communities have preferred property management relationships or even require owners to use on-site management. This affects your net income (management fees typically run 20–35% of gross on Siesta Key) and may restrict how you can list the property on third-party platforms.
What's your lender's position on STR properties? If you're financing, your loan structure may depend on whether the property is classified as an investment property or a second home — and that classification affects your down payment, rate, and qualifying criteria. Investment property financing typically requires 20–25% down and carries a higher rate than second-home financing. How you plan to use the property, including rental intentions, must be disclosed accurately to your lender.
Siesta Key's STR Market: What the Numbers Look Like
Siesta Key is consistently one of the most searched beach destinations in the country — TripAdvisor, Condé Nast, and travel media have ranked it among the top beaches in the US for years. That demand translates directly into STR performance for well-positioned properties in STR-permitted buildings.
For beachfront or Gulf-view condos in buildings that allow 7-night minimums, annual gross revenue in the $80,000–$200,000+ range isn't unusual for actively managed properties. Peak season (January through April, and summer school breaks) drives the majority of that revenue. Shoulder seasons can be surprisingly strong given Siesta Key's year-round appeal.
The critical variable isn't location — it's the building's rental policy. The same unit in a building with a 7-day minimum versus a 30-day minimum will have dramatically different income profiles. Shorter minimums give you access to the highest-rate nights (weekends, holidays, peak weeks), while 30-day minimums push you toward the seasonal tenant market, which has lower nightly rates but more predictable occupancy.
Neither is inherently better — but you need to know which you're buying into before the purchase makes sense financially.
