Key West Vacation Rental Rules: Investor Guide

Can you legally operate a vacation rental in Key West after buying a property?

Not automatically. Key West has some of the strictest short-term rental rules in Florida. A property can only operate as a vacation rental if it sits in a qualifying zoning district, holds an active transient license or medallion, and that license is formally transferred to you at closing. Buying a house does not grant you the right to rent it nightly, the license must already exist and survive the transaction.

I tell every investor who calls me about Key West the same thing: understand the local rental regulations before you make an offer, not after. In a market this technical, the difference between a legal vacation rental and an expensive long-term rental you didn't plan for comes down to due diligence done before you're under contract.

Here's what you need to know.

The Zoning and Licensing Framework You Can't Ignore

Transient vs. non-transient: the 28-day line

Key West draws a hard line between two rental categories. According to the City of Key West residential rental FAQ, non-transient rentals must be 29 days or longer, while transient rentals are 28 days or less. That single distinction determines whether your property can function as a traditional vacation rental or only as a longer-term furnished rental.

If you're modeling short-term rental income, you need a property that qualifies for transient use. Most do not.

Only specific zoning districts allow transient rentals

According to the City of Key West Planning FAQ, a property can only be rented transiently if it sits in one of these districts: HRCC-1, HRCC-3, HCT, HNC-1, or HNC-3. Most conventional residential zoning districts do not permit transient use at all.

That's the investor surprise I see most often. A beautiful Old Town home in a residential zone can only do 29-day-plus rentals, regardless of what the seller implies or what you've seen listed on Airbnb. The Key West Code of Ordinances, Division 7 is explicit: all unlicensed transient rental use of residential dwellings is prohibited. Full stop.

The city also restricts conversion of permanent housing to transient use, particularly in HNC-1 and HNC-3 districts, to prevent erosion of the permanent housing stock. You can't simply rezone or reclassify your way into transient eligibility.

Why Key West's rules have survived state preemption

Florida Statute §509.032(7)(b) generally prohibits local governments from banning vacation rentals or regulating rental duration, but there's a critical carve-out: that restriction does not apply to any local law adopted on or before June 1, 2011. Key West's transient rental framework predates that cutoff, which is why the city can still enforce its tight zoning and licensing rules today.

Due Diligence Before You Make an Offer

Step one: confirm zoning and transient eligibility

Before you write an offer, contact the City of Key West Planning Department directly to confirm the property's zoning district and whether transient rental use is permitted. Don't rely on what the listing says or what a prior owner did, confirm it with the city.

If the property is in a historic district, plan for additional complexity. Historic and transient overlays interact, and approvals can add time and cost to your closing timeline and post-closing plans.

Step two: verify the transient license exists and is transferable

Owning a property in a qualifying zone still isn't enough. The property must hold an active transient license or medallion, and that license must be formally transferred to you. The City of Key West Application for Transfer of Transient Units and/or Licenses requires:

• A current survey and floor plans
• Copies of current occupational licenses for transient rental use, or a letter from City Licensing verifying the number and date of licenses
• A copy of the last recorded deed showing current ownership
• If the property is financed, a letter from the mortgagee consenting to the transfer and proposed use
• If a homeowner or condominium association exists, proof of majority-vote approval per the governing documents

That last two points matter more than most investors expect. Your lender has to sign off on the transient license transfer, and your HOA (if there is one) has to approve it. I've seen these become critical timeline items in escrow, the license transfer can't be finalized until every piece is in place. Work with a local real estate attorney to build contract contingencies tied to successful license transfer before you're committed.

For a deeper look at how the transient license itself works, my post on Key West's transient rental license walks through the mechanics in detail.

Step three: understand the layered licensing requirements

Even after the city transfer is complete, operating legally requires multiple licenses stacked together. Investors generally need:

• A City of Key West vacation rental registration or transient license/medallion, including safety inspection compliance and a designated 24/7 local contact
• A City of Key West Business Tax Receipt (BTR)
• A Florida Department of Business and Professional Regulation (DBPR) vacation rental license
• Registration with the Florida Department of Revenue and the Monroe County Tax Collector for lodging tax collection

Confirm each of these requirements directly with City Licensing, the Monroe County Tax Collector, and Florida DBPR before closing. Requirements can change, and the consequences of operating without the right licenses are serious.

Taxes, Ongoing Compliance, and What It Costs to Operate

The lodging tax stack

Transient rentals in Key West carry a combined lodging tax burden. According to a 2026 regulatory overview citing Monroe County Tax Collector data via Chalet's Key West short-term rental regulations guide, the effective rate is 12.5% total, broken down as:

• 6% Florida state sales tax on transient rentals
• 1.5% county surtax
• 5% Monroe County tourist development tax

Verify current rates with the Monroe County Tax Collector before closing, as tax rules can change. Platforms like Airbnb and Vrbo may collect some of these taxes on your behalf, but the operator remains responsible for accuracy and remittance. A local CPA familiar with Monroe County lodging tax will be worth the cost.

Record-keeping and compliance risk

Mismatches between your state license, city license, and tax accounts, especially when a property has changed hands, can trigger audits or enforcement. If the prior owner held licenses under a different entity or address, clean that up before you start advertising. Don't take bookings until every approval is in place.

Current market context for investors

Recent Zillow market data for the Florida Keys (trailing approximately 90 days, as of August 2026) shows the following area-level medians. Individual property values vary by condition, street, build year, and timing.

Area	Median Sale Price	Median Days on Market
Key West	$1,050,000	49
Big Coppitt	$650,000	32
Cudjoe Key	$1,000,000	60
Summerland Key	$1,400,000	54
Big Pine Key	$745,000	49

Key West's median sits at $1,050,000 with 49 median days on market. There are currently 218 active listings, with 38 new listings added in the past 30 days and 125 homes sold in the trailing 90-day window. Whether a specific property pencils out as a vacation rental investment depends heavily on whether it carries transient rights, and that's a conversation worth having before you spend time underwriting a deal that can't legally operate the way you intend.

If you're also weighing the broader investment picture, my post on Key West real estate investing, ROI, and rental restrictions covers the bigger-picture considerations alongside the regulatory ones.

Every situation is different, and the only way to know whether a specific property can support your investment goals is to run through the due diligence with someone who knows this market. That's exactly the kind of analysis I walk my clients through before we ever write an offer.

Frequently Asked Questions

Can I legally use a Key West single-family home as an Airbnb if it isn't already licensed as a transient rental?

No. According to the Key West Code of Ordinances, all unlicensed transient rental use of residential dwellings is prohibited. If a single-family home doesn't already hold a transient license or medallion and sit in a qualifying zoning district, you can only rent it for 29 days or longer. There is no path to simply "applying" for a new transient license in most residential zones.

Which zoning districts in Key West allow transient vacation rentals, and how do I check if a property qualifies?

The City of Key West Planning FAQ lists the permitted districts as HRCC-1, HRCC-3, HCT, HNC-1, and HNC-3. To confirm a specific property's zoning, contact the City of Key West Planning Department directly before making an offer. Your agent or attorney can also pull the zoning designation from the city's records as part of pre-offer due diligence.

How do I verify that a Key West property has an existing transient license that can be transferred to me?

Confirm directly with City Licensing that the license is current, that there are no outstanding code enforcement or inspection issues, and that the city will approve a transfer to you as the new owner. The formal Transfer of Transient Units and/or Licenses application requires surveys, floor plans, deed copies, lender consent if the property is financed, and HOA approval if applicable. Build this process into your contract contingencies.

What licenses and tax registrations do I need before advertising a Key West vacation rental?

You'll need a city transient license or medallion (with safety inspection compliance), a City of Key West Business Tax Receipt, a Florida DBPR vacation rental license, and registration with both the Florida Department of Revenue and the Monroe County Tax Collector for lodging tax purposes. Confirm each requirement with the relevant agency before closing, and don't advertise or accept bookings until every approval is in hand.

How much lodging tax applies to transient stays in Key West, and who collects it?

As of mid-2026, the commonly cited combined rate is 12.5%, consisting of 6% Florida state sales tax, a 1.5% county surtax, and a 5% Monroe County tourist development tax, according to a 2026 regulatory overview citing Monroe County Tax Collector data. The operator is responsible for collecting and remitting these taxes accurately, even if a booking platform collects a portion. Verify current rates with the Monroe County Tax Collector, as rates can change.

What's the difference between a non-transient and transient rental in Key West, and how does it affect my investment strategy?

Non-transient rentals are 29 days or longer; transient rentals are 28 days or less, per the City of Key West residential rental FAQ. If your investment model depends on short-term vacation rental income, you need a property that is zoned for transient use and already holds an active transient license. A property without those qualifications can still generate rental income, but only through longer-term furnished rentals, a meaningfully different income profile.

Key West's vacation rental rules are genuinely complex, and the stakes of getting them wrong are high. If you're evaluating an investment property here, the smartest move is to work with a local agent and a local attorney from the very beginning. Call me to schedule a complimentary consultation, I'll help you identify properties that actually qualify and walk you through the due diligence process before you're committed to anything.
