Key West has some of the most restrictive short-term rental regulations in Florida—and the United States. Once a vacation rental paradise, the island city has dramatically limited new STR licenses to preserve housing stock and manage tourist density. If you own property in Key West and want to operate a vacation rental, you need to understand the fundamental reality: new licenses are nearly impossible to obtain, and only grandfathered properties can legally operate.
Awning manages 20,000+ vacation rental properties across all 50 states, including many in the Florida Keys. This guide explains Key West's STR licensing landscape, the grandfathering rules, the overlapping Monroe County and City regulations, and what options remain for property owners in 2026.
Key West STR Ban: What Actually Changed
Key West did not implement a complete STR ban, but it did something functionally similar: it stopped issuing new transient rental licenses in most residential neighborhoods in 2018. This distinction matters legally, but the practical impact is the same—new STR operations in residential Key West are not permitted. To understand how Key West's rules compare to other states, review our comprehensive guide to short-term rental regulations.
2018 Policy ChangeIn 2018, the City of Key West stopped accepting new applications for transient rental licenses in residential districts. Properties that held valid licenses before this date are grandfathered—they can continue operating and renew indefinitely. Properties without pre-2018 licenses cannot legally operate short-term rentals.
What "Grandfathered" Means
A grandfathered property is one that held a valid transient rental license from the City of Key West before the 2018 cutoff. Grandfathered licenses are:
- Renewable indefinitely (no expiration that prevents renewal)
- Transferable to a new owner (with the property)
- Protected from the residential ban
Non-Grandfathered Properties
If your property does not have a grandfathered license, you cannot operate an STR in Key West residential zones, period. Airbnb and VRBO actively delist non-compliant properties when notified by the city.
Commercial Zones Exception
Key West does allow transient rentals in commercial zoning districts and on properties with commercial licenses. However, most residential properties are zoned residential, making this exception impractical for typical homeowners.
Transient Rental Licenses and Grandfathering
Understanding Key West's license structure is critical to legal operation.
Transient Rental License DefinitionA transient rental license is Key West's official authorization to operate a short-term rental. The city issues licenses for specific properties, not owners. When a property changes hands, the license transfers with the deed—but only if the property was grandfathered.
Checking Grandfathering StatusYou can verify a property's grandfathered status by:
- Contacting Key West Community Development Department directly at (305) 809-3700
- Requesting a "Certificate of Transient Rental License" or proof of license history
- Hiring a local real estate attorney to research the property's licensing history
Before buying any Key West property, hire a lawyer to verify grandfathering status. This is non-negotiable. A property without grandfathered status has zero legal STR potential.
Renewal Requirements
Grandfathered licenses must be renewed annually. Renewal requires:
- Payment of annual license fee
- Proof of insurance (liability and property) — see our guide on Airbnb insurance requirements
- Up-to-date local contact information
- Compliance with city codes (no outstanding violations)
If you fail to renew your license, your grandfathered status is forfeited, and you cannot re-apply.
Transfer of Grandfathered License Upon Sale
When you sell a grandfathered property, the new owner inherits the license if the property is transferred with the deed. However, the new owner must formally register with the city and obtain their own license under their name/ownership entity.
Monroe County vs. City of Key West Regulations
Key West is in Monroe County, and both jurisdictions have STR regulations. Understanding the overlap is critical.
City of Key West Regulations (Most Restrictive)
The City of Key West imposes:
- The residential ban on new STR licenses (2018 onward)
- Occupancy limits and house rules
- Nightly cap enforcement (often 3–5 guests maximum for residential)
- Neighborhood noise and parking ordinances
- Annual license renewal requirements
Monroe County Overlay
Monroe County sits above the City of Key West and has separate regulations. Monroe County does not ban STRs but requires:
- Monroe County tourist development tax license (separate from city license)
- Compliance with county environmental and building codes
- County-level inspections for safety and code compliance
Which Applies to You?
If your property is within the City of Key West limits, you must comply with both City and County regulations. City rules typically are more restrictive, so comply with the City first.
Tourist Development Tax (Monroe County)
Monroe County levies a 5% tourist development tax (TDT) on nightly rental rates. This is separate from any city tax and must be collected and remitted to Monroe County monthly.
The Key West Blight Ordinance and Restrictions
Key West's Blight Ordinance further restricts STR operation and property maintenance standards.
What the Blight Ordinance Does
Enacted to preserve Key West's historic character and prevent property neglect, the Blight Ordinance:
- Requires transient rental properties to meet strict aesthetic and maintenance standards
- Prohibits visual impacts on neighborhoods (excessive signage, trash bins, vehicle clutter)
- Limits guest vehicle parking and requires documented parking arrangements
- Mandates regular property inspections and maintenance
Specific Restrictions for STRs
Properties operating as transient rentals must:
- Not display permanent vacation rental signage
- Maintain landscaping to city standards
- Manage waste bins out of public view
- Provide off-street parking for guests (very difficult in Key West's historic district)
- Remove or upgrade any rundown exterior elements
Enforcement
The city conducts routine inspections of licensed transient rental properties. Violations of the Blight Ordinance can result in fines, license suspension, or revocation.
License Application and Renewal Process
If your property is grandfathered, here's how to maintain your license:
Annual Renewal Timeline
- Licenses expire annually on December 31st
- Renewal applications must be submitted by November 30th
- Late applications may face penalties or license lapse
Renewal Documentation Required
- Copy of current homeowners insurance policy
- Proof of liability insurance (minimum $1 million general liability)
- Current local property manager contact information (if applicable)
- Proof of property tax payment
- Declaration of compliance with Blight Ordinance
Renewal Fees
Annual transient rental license renewal fees are approximately $500–$1,000 per year, depending on property type and size. Fees have increased in recent years as the city funds enforcement.
Inspection Requirements
City inspectors may conduct unannounced inspections to verify code compliance. Properties must be in safe, habitable condition, free of health/safety hazards, and compliant with the Blight Ordinance.
Online Renewal Portal
Key West has implemented an online portal for some license renewals. Check keywestcity.us for current procedures. Many landlords use local property managers who handle renewal paperwork.
Fees, Taxes, and Operating Costs
Operating a transient rental in Key West is expensive due to licensing, taxes, and enforcement.
Annual Licensing Costs
Tourist Development Tax (Monroe County)
5% of nightly rental revenue must be remitted to Monroe County monthly. This is a direct reduction to your income.
City Occupancy Tax (If Applicable)
Some Key West agreements may include city occupancy taxes (typically 2–3%). Verify your specific property's tax obligations.
Sales Tax
Florida sales tax (6.5% in Monroe County) applies to short-term rentals. You must collect and remit this monthly.
Property Tax Impact
Operating a property as a transient rental may trigger a property tax reclassification, increasing your annual property tax burden. Consult your Monroe County Property Appraiser.
Insurance Costs
Standard homeowners insurance excludes short-term rental liability. You must obtain a vacation rental or commercial liability policy, typically adding $1,500–$3,000+ annually.
Penalties for Operating Without a License
Key West enforces its STR regulations aggressively. Operating without a valid transient rental license carries serious consequences.
Fines and Citations
- First violation: Written warning or fine up to $500
- Subsequent violations: Fines up to $1,000–$5,000 per violation
- Violations are typically assessed per day of illegal operation
Platform Delisting
Airbnb, VRBO, and Booking.com automatically delist unlicensed Key West properties when notified by the city. Once delisted, re-listing is difficult, even after obtaining compliance.
Code Enforcement ActionsKey West Code Enforcement may:
- Issue cease-and-desist orders
- Place liens on your property
- Initiate eviction or lease termination proceedings for renters
- Recommend criminal prosecution for repeat violations
Criminal Liability
Egregious or repeat violations of Key West STR ordinances can result in misdemeanor charges, though this is rare.
Guest Liability
Operating an unlicensed STR without proper insurance exposes you to severe personal liability if a guest is injured. Your homeowners policy will not cover unlicensed short-term rental activities.
Your Options If You Cannot Get Licensed
If your Key West property does not have a grandfathered transient rental license, operating as an Airbnb is not legal. However, you have alternatives.
Option 1: Long-Term Rentals
Rent your property to a long-term tenant (6+ months). Long-term rentals are unaffected by the STR ban and can generate 70–80% of short-term rental income with far fewer regulations. For more on STR vs. long-term rental strategies, see our comprehensive comparison.
Option 2: Purchase a Grandfathered Property
If you want to operate an STR in Key West, purchase a property that already has a grandfathered license. Expect to pay a premium for the grandfathered status—sometimes 10–20% above market value. Work with a local real estate attorney to verify and transfer the license.
Option 3: Commercial Zone Property
Purchase or lease property in Key West's commercial zoning districts (near downtown Duval Street). Commercial properties can obtain new transient rental licenses. However, purchase prices are significantly higher, and inventory is limited.
Option 4: Nearby Areas
Consider properties in unincorporated Monroe County (Key Largo, Islamorada, Marathon, or Big Pine Key). These areas have less restrictive STR regulations and lower operating costs. Many investors have shifted focus to the Upper Keys as Key West licensing has tightened.
Frequently Asked Questions
Q: Can I get a new transient rental license in Key West in 2026?
A: No, not in residential zones. The city stopped issuing new licenses in residential areas in 2018. Only grandfathered properties can operate. Commercial zones may have limited availability—consult the city's development department.
Q: If I buy a property in Key West, how do I know if it has a grandfathered license?
A: Hire a local real estate attorney to research the property's license history. Request documentation from the city directly at (305) 809-3700 or visit the Key West Community Development Department office.
Q: What happens if I inherit a Key West property with a grandfathered STR license?
A: You inherit the right to operate the license if the property is transferred to you. You must register with the city, renew the license under your name, and comply with all ongoing requirements. Consult an attorney to ensure proper transfer.
Q: Can I operate an STR on Airbnb without a Key West license?
A: No, and Airbnb will delist your property if the city reports it. Operating without a license is illegal and subjects you to fines, liens, and potential legal action.
Q: How much does a grandfathered STR license cost when buying a property?
A: The license doesn't cost extra as a separate purchase. However, properties with grandfathered licenses typically sell at a 10–20% premium over comparable properties without licenses. This reflects the market value of the license.
Q: Do I have to renew my Key West STR license every year?
A: Yes. Licenses expire December 31st and must be renewed by November 30th. Failure to renew results in license lapse and forfeiture of grandfathered status.
Q: What if my property is in unincorporated Monroe County (not City of Key West)?
A: Different rules apply. Unincorporated Monroe County areas are less restrictive than the City of Key West. You still need a license and must comply with county codes, but the residential ban does not apply to unincorporated areas.
Q: Can I challenge the city's decision to restrict new STR licenses?
A: The City of Key West's 2018 policy is established law. Individual property owners cannot easily challenge it. Collective advocacy through property owner groups or the Monroe County Tourist Development Council is the only realistic path for policy change.
