Thinking about buying a vacation rental in Key West or Stock Island? It can be an exciting way to own a place in the Lower Keys while creating income potential, but this is not a market where you can make broad assumptions. Rental use here is highly parcel-specific, rules can change by zoning and jurisdiction, and costs like taxes, insurance, and compliance matter just as much as the purchase price. If you want to buy with confidence, it helps to understand how these two areas differ and what to verify before you make an offer. Let’s dive in.
Key West vs. Stock Island
If your goal is strong visitor-driven demand, Key West is the more tourism-centered market. According to the Monroe County 2023 Economic Impact Study, visitors spent $1.3 billion in Key West in 2023, including $787.7 million on accommodations. That gives you helpful context for why vacation-rental interest remains high.
Stock Island has a different feel and function. County planning materials describe it as a mixed-use, working-waterfront area with marina, light industrial, commercial retail, residential, and boat-storage uses, according to Monroe County planning documents. For you as a buyer, that can mean a broader mix of property types and a setting that is not as purely tied to the tourist core.
Rental Rules Are Parcel-Specific
One of the biggest mistakes buyers make is assuming short-term rental use applies across a whole neighborhood. In Key West and Stock Island, that is not how it works. Whether a property can be rented short term depends on the exact parcel, the governing jurisdiction, and the applicable zoning or land-use rules.
That means your due diligence needs to start with the property itself, not with what a nearby home appears to be doing. A listing’s marketing language is never enough on its own. You want direct confirmation from the proper city or county sources before moving forward.
Key West Short-Term Rental Rules
In the City of Key West, transient use is zoning-driven. The city states that a property can be rented transiently only in HRCC-1, HRCC-3, HCT, HNC-1, and HNC-3 zoning districts, as outlined by the Key West Planning Department.
The city defines transient lodging as stays of less than 30 days or one calendar month. It also treats a property as transient if it is advertised or held out for that kind of use, even if no actual rental occurs. That is an important detail if you are evaluating future income potential and online marketing strategy.
There is another layer to keep in mind. The city also limits redevelopment or conversion of permanent housing to transient or other commercial uses in parts of HNC-1 and HNC-3 when on-site permanent housing would be reduced. In other words, even if an area has some transient activity, you still need to verify what is allowed at the specific address.
Key West Licensing Requirements
If you buy a property in Key West that is eligible for residential rental use, you will also need to look at licensing. The city requires a Business Tax Receipt for residential rentals, and those renew annually from October 1 through September 30.
The city also maintains a map of licensed transient properties. That is another reminder that this market is address-specific, not broad-brush by area. It is also wise to confirm that any property you are considering is properly licensed before you rely on its past rental history.
Stock Island Rules in Unincorporated Monroe County
On Stock Island, many properties fall under unincorporated Monroe County rules rather than the City of Key West. Monroe County’s vacation-rental program says not all areas allow short-term rentals, and allowed land-use districts include SR, MU, UR, IS-V, and OS. Prohibited districts include IS, URM, and IS-M, with limited exceptions in certain gated communities that have controlled access and an approved association.
The county defines a special vacation rental as a stay of less than 28 days. Before renting, owners must obtain an annual permit, have a manager license, and secure a business tax license. This is one reason buyers often benefit from working with local professionals who understand how county procedures play out in real time.
Permits Do Not Always Transfer
This point deserves extra attention: do not assume a vacation-rental permit transfers with the property. Monroe County clearly states that the special vacation-rental permit is nontransferable between owners.
If ownership changes, the new owner must submit a new permit application. That can directly affect your timeline, your carrying costs, and how soon the property may be able to operate as a rental. If you are underwriting a purchase based on projected income, this step should be part of your planning from day one.
Taxes Can Affect Your Returns
When buyers run numbers, they often focus on nightly rates and occupancy. Just as important are the layered taxes tied to short-term rentals in Florida and Monroe County.
The Florida Department of Revenue says transient rentals are subject to the 6% state sales tax plus any applicable county surtax, and Monroe County’s total state and local sales and use tax rate is 7.5%. Separately, Monroe County also imposes tourist development taxes, and the practical takeaway is simple: you should expect multiple lodging-related tax layers and confirm collection and filing responsibilities before closing.
If you are buying for part-time personal use and part-time rental use, those tax questions become even more important. A tax professional can help you understand what applies to your ownership structure and rental plan.
Insurance and Flood Costs Matter Early
In the Florida Keys, insurance is not just a line item to estimate later. It is a core part of whether a property still makes financial sense once the full cost of ownership is clear.
According to Monroe County’s flood information resources, all of Monroe County is in a floodplain, with base flood elevations ranging from 6 to 17 feet above mean sea level. The county also notes that flood damage is not covered by standard homeowner’s insurance. That means you should look closely at flood insurance needs, elevation data, and prior flood or drainage history before you finalize a purchase.
A smart approach is to check FEMA flood maps by address and request any available elevation certificates early in the process. Florida law also requires sellers and agents to disclose known natural hazards, including flooding, which makes these conversations a key part of your due diligence.
Local Management Can Make a Big Difference
Owning a vacation rental from afar sounds easy until renewals, inspections, guest turnover, and vendor coordination start stacking up. In this market, local management and on-the-ground support can save you time and reduce mistakes.
Monroe County’s Fire Marshal inspection guidance notes that owners should have the DBPR license, county business tax receipt, and any planning permit or application on site when a vacation-rental inspection is requested. That is a clear sign that compliance is active and ongoing, not something you handle once and forget.
Even in Key West, annual renewals and active license tracking are part of the ownership experience. If you are buying as a second-home owner or investor, it helps to line up a local manager or support team before you need one.
Due Diligence Checklist
Before you buy a vacation rental in Key West or Stock Island, make sure you verify these items for the exact property:
- Confirm the property’s zoning or land-use designation
- Verify whether short-term rental use is allowed at that address
- Confirm what licenses or permits are required
- Ask whether any current approvals transfer with the sale
- Review tax collection and filing responsibilities
- Price out flood, wind, and homeowner’s insurance early
- Request elevation certificates and available flood history
- Understand inspection requirements and renewal timelines
- Identify a local manager or trusted service providers
A vacation rental can be a great fit for your lifestyle and long-term goals, but only when you buy with a full picture of the rules and carrying costs. The right property is not just appealing on paper. It is one that aligns with your intended use, your risk comfort, and your ability to operate it smoothly.
