Sanibel and Captiva STR Rules 2026: The 28-Day Rule

Sanibel limits single-family lettings to 28 days or more. Weekly letting exists only in named grandfathered complexes, so the building you buy is the rule.

Quick answer: On Sanibel the letting rule is attached to the property, not to the owner. Single-family homes are limited to lettings of no less than 28 days. Weekly letting exists, but only in specific grandfathered complexes that carried the right before the rules were fixed. So the question at purchase is not what you intend to do; it is which building you are buying into, and that answer cannot be changed afterwards.


The rule attaches to the building

Most Florida short-stay questions are about what an owner may do. On Sanibel the question is what a property may do, and the two are not the same.

Property typeTypical letting position
Single-family homeno less than 28 days
Condominium in a grandfathered complexweekly letting permitted
Condominium in a non-grandfathered complexthe longer minimum applies

Grandfathered status was earned by historical use and zoning long before any current owner arrived. It travels with the property when it sells and it cannot be applied for, negotiated or created by intention.

The consequence at purchase is stark. Two condominium units of similar size and finish, a short distance apart, can support entirely different businesses and therefore justify entirely different prices. A buyer paying a weekly-letting price for a unit without the right has bought the wrong asset, and no amount of subsequent effort corrects it.

Verify the status in writing, from the city and from the complex’s own documents, before the offer. A listing describing a property as a rental, or a seller’s account of what neighbours do, is not verification.

Why the island can do this

Florida Statute 509.032(7)(b) prevents a local government from prohibiting vacation rentals or regulating stay duration or frequency, and the preemption carries a date: it does not reach any local law adopted on or before 1 June 2011.

Sanibel’s rules predate that line. They survive, and they may be amended only to become less restrictive. That is why a Florida city can enforce a 28-day minimum in 2026 when no city could newly adopt one today.

The same clause explains the pattern across Florida’s most protected coastal communities. Where you find an unusually restrictive rule in this state, the explanation is almost always the date of the ordinance rather than a recent policy choice.

Preemption also leaves registration and inspection programmes untouched, along with generally applicable rules on occupancy, parking, noise, waste and life safety.

Two different thresholds, 28 and 30

The island’s rule is 28 days. The state licensing test turns on 30 days. That two-day gap has a practical consequence worth understanding.

RuleThresholdWhat it governs
Sanibel single-family minimum28 dayswhether the letting is permitted at all
DBPR vacation rental licence testunder 30 days, more than 3 times a year, or advertised as regularly availablewhether a state licence is required
Transient taxes6 months or lesswhether tax is due

A property let strictly in 28-day blocks is compliant with the city and still sits under the 30-day licensing line, so the DBPR vacation rental licence test can be met. Letting instead in blocks of 30 days or more satisfies the city rule with room to spare and moves the property above the licensing threshold on the frequency limb, although the advertising limb still applies to a publicly listed property.

That is a genuine planning decision rather than a technicality, and it is worth taking before the first booking rather than after.

The 5% and who remits it

ComponentRateWho remits it
Florida state sales tax on transient rentals6%commonly the platform, on its own bookings
Lee discretionary sales surtaxcounty surtax, where leviedwith the state component
Lee County tourist development tax5%Airbnb on its bookings; the owner on everything else

Lee is county-collected and Airbnb collects for its own bookings. Everything else is yours, and on an island where a large share of letting runs through established local rental managers and repeat guests rather than through platforms, that share is substantial.

Open the county account before the first letting and keep two figures: rent where a platform collected the county tax, and rent where nobody did. See Lee County and tourist development tax by county.

Monthly letting is the island’s normal business

Because the minimum is 28 days for most stock, the dominant model here is monthly rather than weekly, and its economics differ from a nightly beach market in every line.

Turnover cost nearly disappears. One changeover a month instead of four or eight transforms the cleaning line.

Guests are different. Monthly visitors are seasonal residents and long-stay families rather than weekend holidaymakers, and they want storage, a full kitchen, laundry and a car space more than they want styling.

The season is concentrated. Winter demand is strong and the summer is quieter, so the annual model rests on a smaller number of larger bookings, and each unfilled month is a visible gap rather than a rounding error.

Vacancy is lumpy. Underwrite the gaps explicitly. A model with no void allowance between monthly bookings is the one that disappoints.

Ask for 3 years of actual occupancy and achieved monthly rent from comparable properties under the same letting rule, not island averages.

Insurance and the barrier island

Wind and flood are normally written separately from the dwelling policy here, and a letting operation needs liability cover written for that use.

Get real quotes for the specific address and elevation, ask the seller for 3 years of actual premiums and the claims history, and obtain the flood zone and elevation certificate. On a low barrier island these documents drive the numbers more than the purchase price does. See the Citizens insurance guide and the 1 million dollar liability requirement.

On a condominium, establish what the master policy covers, what it excludes and what an owner’s own policy must bridge, and ask for the reserve position alongside it.

The association can be stricter still

Even in a grandfathered complex, the recorded declaration governs what an individual owner may do, and it can impose caps on lettings per year, approval procedures, waiting periods after purchase and rental programme requirements.

An association cannot make a prohibited letting lawful and it can restrict further. Read the recorded declaration with amendments before offering. See the HOA and association restrictions checklist.

Financing

Lenders price a letting purchase differently from a second home, so state the intended use at application. Conventional investment lending, a DSCR loan underwritten on the property’s own income, or cash are the usual routes, and overseas buyers work through foreign national mortgage programmes.

On a condominium, add the project questionnaire early. Reserve funding and owner-occupancy are project-level tests, and a building that fails them removes conventional lending for every owner in it rather than for one applicant.

Before you buy on Sanibel or Captiva

  • Establish in writing whether the property may be let weekly or only in blocks of 28 days or more.
  • Verify any grandfathered status with the city and from the complex’s own documents.
  • Draw comparables only from properties under the same letting rule.
  • Decide deliberately between 28-day and 30-day blocks, and note the licensing consequence.
  • Open the Lee County tourist tax account before the first letting.
  • Track platform rent and non-platform rent as separate figures.
  • Get 3 years of occupancy and achieved monthly rent from comparable properties.
  • Get the flood zone, elevation certificate, 3 years of premiums and the claims history.
  • Read the recorded declaration for letting caps, approvals and waiting periods.

Where this leaves an investor

Sanibel and Captiva are protected, low-density islands whose letting rules have shaped the market for decades and will continue to. That protection is much of why the property is worth what it is, and it is also why the rental model is monthly rather than weekly for most of the stock.

Buy the rule you want along with the property, because you cannot acquire it afterwards. Verify the status in writing before the offer, and then run what is in practice a low-turnover, seasonal letting business rather than a nightly one. For the county position see Lee County.

Frequently Asked Questions

Generally no. The City of Sanibel limits the letting of single-family homes to periods of no less than 28 days. Weekly letting on the island is concentrated in specific condominium complexes that hold grandfathered status permitting shorter stays, and those are the exception rather than the rule.

Certain named condominium and resort-style complexes carry grandfathered status allowing weekly rentals. That status attaches to the property, not to the owner, so the question at purchase is which complex you are buying into rather than what you intend to do. Verify the status in writing with the city and from the complex's own documents.

Florida Statute 509.032(7)(b) preempts local prohibitions and local regulation of stay duration or frequency only for ordinances adopted after 1 June 2011. Rules in place on or before that date survive and may be amended only to become less restrictive, which is why the island's long-standing minimum stay rules continue to apply.

5% on lodging of 6 months or less. Lee is a county-collected jurisdiction and it is one of the counties for which Airbnb collects and remits the county tax on its own bookings. Rent from other channels and direct bookings remains the owner's to collect and remit.

Yes. The transient taxes attach to lodging of 6 months or less, so a 28-day or 90-day letting is fully taxable. The 28-day rule is a city land use rule and the 6-month line is a tax rule, and they are different thresholds serving different purposes.

The transient public lodging test turns on lettings for periods under 30 days, more than 3 times a year, or advertising the property as regularly available for such stays. A property let strictly in blocks of 28 days sits under 30 days and can therefore meet the test. Confirm the position for your actual pattern of use.
