Key West Vacation Rental Rules Buyers Must Check First

What rules apply to a Key West vacation rental purchase?

A Key West vacation rental is only as valuable as its legal right to rent for short stays, and that right is tied to the specific parcel. Key West is an incorporated city with its own licensing path, while unincorporated Monroe County runs a Special Vacation Rental Permit program for stays of fewer than 28 days. Confirm which jurisdiction and zoning district govern the property before you trust any income projection.

Key Takeaways

• Homes sold in Key West over the roughly 90 days ending October 2026 had a median sale price of $1,012,500, so a rental-rule mistake is an expensive one.
• In unincorporated Monroe County, a dwelling rented for fewer than 28 days needs an annual Special Vacation Rental Permit unless an exemption applies.
• In the Improved Subdivision (IS), Urban Residential Mobile Home (URM), and Improved Subdivision Masonry (IS-M) districts, advertising or offering a stay of fewer than 28 days is unlawful.
• The county's published permit application fee is $490 for an initial permit and $100 for a renewal, but that is only one line in the real compliance picture.
• If a property is already operating as a rental, get written confirmation of its license status, expiration, inspection history, and whether anything transfers to you on sale.

Is a Key West vacation rental governed by the city or Monroe County?

It depends on whether the parcel is inside the City of Key West or in unincorporated Monroe County, and the licensing path is different for each. That is the very first question I answer when a buyer calls about a rental property.

The Keys run a long way, from Key West and Stock Island out through Big Coppitt, Summerland Key, Cudjoe Key, and Big Pine Key. The same island, subdivision, or even street can carry different land-use designations. A listing that says "great rental income" tells you nothing about what the parcel is actually allowed to do.

Here's the market backdrop. Recent local market data shows 238 homes for sale now in Key West, with 66 new listings in the last 30 days and 96 homes sold in roughly the last 90 days. The median sale price for those sold homes was $1,012,500. Price alone doesn't tell you whether a parcel can be rented short term, which is why I put zoning and licensing ahead of the pro forma.

These are area-level medians. An individual home's value depends on condition, street, and timing, and its rental eligibility depends on its parcel. For a deeper look at how the rules differ across the island chain, see my Florida Keys vacation rental regulations explainer.

What does Monroe County require to run a vacation rental legally?

For a property in unincorporated Monroe County, you need an annual Special Vacation Rental Permit before renting for fewer than 28 days, unless the property has an applicable exemption. The county defines a "special vacation rental" as a dwelling rented for fewer than 28 days, and spells out the program on its Special Vacation Rental Program page.

Does the zoning district allow it?

Zoning is the gate, and it's checked parcel by parcel. The county lists which land-use districts prohibit short stays and which may allow them with a permit:

Don't infer eligibility from the neighborhood or from what the current owner is doing. A property can be rented short term today and still not be lawful to do so.

What are the permit fee and inspection requirements?

The county's published application fee is $490 for an initial permit and $100 for a renewal, according to the county's program page. Those are application fees only, not an estimate of your total operating or compliance costs.

Both initial and renewal permits require a Fire and Life Safety Inspection by the Fire Marshal's office. Since the permit is annual, you'll want to know its expiration date, whether any corrections are outstanding, and whether a renewal is pending before you count on current rental income.

Who has to manage the rental, and what other licenses apply?

Each permitted unit must have a vacation-rental manager holding a special vacation-rental manager license issued by Planning and Environmental Resources. The county also states that all rentals, long-term and short-term where allowed, require a business tax license.

Ask who holds the manager license, whether management is in-house or a third party, and what happens to that arrangement when ownership changes.

Can you advertise weekly rentals in a district that prohibits them?

No. In a district where stays under 28 days are prohibited, the county's guidance calls for 28-day minimum stays and monthly rental or lease rates. Swapping the words "vacation rental" for "monthly rental" doesn't authorize shorter stays. If a listing's photos and marketing say "book by the night," treat that as a diligence flag, not a selling point.

What should you verify before buying a property that's already operating as a rental?

Get written confirmation of the property's license status, the zoning district, and whether anything transfers to you on sale. A seller's income statement doesn't answer any of those questions.

When a Key West vacation rental is already in operation, here's the list I work through with buyers:

1. Jurisdiction. Is the parcel inside the City of Key West or in unincorporated Monroe County?
2. Zoning. Which land-use district applies to this exact parcel, and does it allow stays under 28 days?
3. License status. Ask the City of Key West, in writing, whether the property has a valid license, whether it is tied to the property or to the current holder, whether it can transfer on sale, and whether any violations or unpaid fees are attached to the account.
4. County permit and inspection. For county parcels, get the permit expiration date, the latest Fire and Life Safety Inspection result, and any open corrections.
5. Manager license. Confirm who holds it and whether that person or company stays on after closing.
6. Business tax license. Confirm it's in place and in good standing.
7. Condo or HOA rules. Association documents can restrict rentals on their own, separate from government rules.

Your real estate attorney should see these confirmations before your contingency period runs out. I coordinate that timeline with my buyers so nobody is chasing a records request the week of closing.

Is the rental income worth the compliance work?

Possibly, but the tourism numbers alone won't tell you. Visit Florida Keys reported that vacation-rental revenue on the books for October through December 2026 was $15.3 million, up 6.9% year over year, in its October 5, 2026 snapshot. An earlier July 27, 2026 snapshot showed $14.3 million on the books for July through October, up 23.9%. That report noted a data correction tied to a property-manager portfolio transition and an updated supply count, so treat it as booking pacing, not a full census.

Either way, this is Keys-wide booking data. It says nothing about what one Key West property will earn, or whether it's even eligible. Before I'd lean on a revenue projection, I want the license and zoning answers in hand, then a realistic look at seasonality, management, insurance, and maintenance. Insurance in particular can change the math; my breakdown of insurance costs for Key West buyers is a good companion read.

If you're buying for income, learn the rental rules before you write the offer, not after. Our Key West vacation rental rules investor guide and our post on short-term rental rules and Florida Keys luxury real estate go further on strategy.

Your numbers depend on the parcel, the license, and your plan for the property. The way to know for sure is to run them with someone who works this market every day.

FAQ

Can I legally operate a vacation rental at this Key West property?

Only if the specific parcel's jurisdiction, zoning, and licensing allow it. First determine whether it's in the City of Key West or unincorporated Monroe County, then confirm the land-use district and license status in writing. Current use as a rental doesn't prove it's lawful.

Does Key West still issue new transient rental licenses?

That's a question for the City of Key West, and you should get the answer in writing for the specific property. I wouldn't price an offer on the assumption that a new license is available. If a license already exists, ask whether it can transfer on sale and whether any violations or unpaid fees are attached.

What is the difference between a Key West license and a Monroe County vacation-rental permit?

They come from different jurisdictions. Key West is an incorporated city with its own licensing path, while the Monroe County Special Vacation Rental Permit applies to properties in the county's jurisdiction. Which one applies depends on where the parcel sits.

What zoning districts in unincorporated Monroe County allow rentals of fewer than 28 days?

The county identifies Suburban Residential (SR), Mixed Use (MU), Urban Residential (UR), Improved Subdivision Vacation Rental (IS-V), and Offshore Islands (OS) as districts where vacation rentals may be allowed, subject to permit requirements. Improved Subdivision (IS), Urban Residential Mobile Home (URM), and Improved Subdivision Masonry (IS-M) prohibit stays under 28 days. Confirm the district for your exact parcel.

Can I advertise weekly rentals if the zoning requires 28-day minimum stays?

No. In a district where short-term rentals are prohibited, the county's guidance requires 28-day minimum stays and monthly rental or lease rates. Rewording the ad doesn't change what the zoning allows.
