Key West, FL Airbnb & Short-Term Rental Regulations 2026
Key West is one of Florida's most strictly regulated STR markets. Understand the license caps, zoning restrictions, Historic Preservation requirements, and why new investors face significant barriers to entry in this premium vacation destination.
Key West stands out as one of the most challenging markets in Florida - and indeed the entire United States - for new short-term rental investors. With strict license caps, zoning restrictions that prohibit STRs in most residential areas, and Historic Preservation requirements for Old Town properties, entering this market requires extensive due diligence and often significant luck in timing.
Regulation Overview
Key West's short-term rental regulations are among the strictest in Florida, designed to preserve the character of this small island community while managing the impacts of tourism. The City of Key West defines a transient rental as any dwelling unit rented for periods of less than 28 consecutive days.
Why Key West is Different
Unlike many Florida destinations that have struggled to regulate STRs, Key West established comprehensive controls decades ago. The island's small geographic size (approximately 4.2 square miles), limited housing stock, and status as a major tourist destination created early pressure to limit transient rentals in residential neighborhoods.
Key Regulatory Bodies
- City of Key West Planning Department: Issues transient rental licenses and enforces zoning compliance
- City of Key West Code Compliance: Investigates violations and issues citations
- Historic Preservation Review Board (HPRB): Reviews STR applications in the Historic District
- Monroe County Tax Collector: Administers Tourist Development Tax
- Florida Department of Revenue: Oversees state sales tax collection
License Cap & Availability
The most significant barrier to entry in Key West is the strict cap on transient rental licenses. The city has implemented a ceiling on the total number of licenses available, and this cap has been at or near capacity for years.
How the License Cap Works
- Fixed Maximum: The city maintains a cap on total transient rental licenses
- No Automatic Availability: When a license is surrendered or revoked, it does not automatically become available
- Zone-Specific Allocation: Available licenses are allocated based on zoning district requirements
- No License Transfer: Licenses cannot be sold, transferred, or inherited with property
- Annual Renewal Required: Existing licenses must be renewed annually and can be revoked for violations
License Application Process
Contact Planning Department BEFORE purchasing property to confirm licenses are available in your zoning district
Property must be in a commercial or transient zoning district - most residential zones prohibit STRs
Properties in Old Town require Historic Preservation Review Board approval
Pass required fire and safety inspection by city inspectors
Register for state sales tax and Monroe County Tourist Development Tax collection
Submit application with required fees, insurance documentation, and property information
Zoning: Transient vs Residential
Understanding Key West's zoning is absolutely critical before considering any STR investment. The city's zoning code strictly limits where transient rentals can operate, and most of the island's residential areas completely prohibit short-term rentals.
Zoning Districts and STR Eligibility
| Zoning Category | STRs Permitted | Notes |
|---|---|---|
| Historic Transient Residential (HMDR/HTR) | Yes (with license) | Primary zone for legal STRs; HPRB approval required |
| Commercial Zoning Districts | Yes (with license) | Mixed-use and commercial properties may qualify |
| Historic Residential (HR) | NO | Long-term residential only; STRs prohibited |
| Single Family (SF) | NO | Strictly residential; no transient rentals |
| Medium Density Residential (MDR) | NO | Residential zone; STRs prohibited |
| Low Density Residential (LDR) | NO | Residential zone; STRs prohibited |
The Transient Zone Reality
Key West's transient zones are limited to specific areas, primarily concentrated in Old Town and along certain commercial corridors. Key considerations:
- Limited Geography: Transient-eligible zones represent a small fraction of the island's total area
- High Property Values: Properties in transient zones command significant premiums due to STR eligibility
- Existing Competition: Most transient-zone properties are already operating as STRs or hotels
- HOA Restrictions: Even in eligible zones, some condominiums and HOAs prohibit or restrict STRs
Historic District Rules (Old Town)
Key West's Historic District, commonly known as Old Town, encompasses much of the island's most desirable real estate. Properties in this area face additional regulatory requirements through the Historic Preservation Review Board (HPRB).
HPRB Review Requirements
The Historic Preservation Review Board must approve various aspects of STR operations in the Historic District:
- Exterior Modifications: Any changes to the building's exterior, including paint colors, signage, and landscaping
- Signage: All exterior signage advertising the rental must be approved for size, style, and placement
- Parking Modifications: Changes to driveways, parking areas, or access points
- Structural Changes: Any additions, modifications, or alterations to historic structures
- Character Preservation: Operations must not negatively impact the historic character of the neighborhood
HPRB Application Process
Meet with Historic Preservation staff to discuss plans and requirements
Submit detailed plans, photographs, and documentation of proposed changes
HPRB reviews application at public meeting; neighbors may provide input
Approved changes must be implemented exactly as approved; inspections may follow
