Thinking about turning your Key Biscayne second home into reliable income, but unsure where to start? You are not alone. The island’s high demand and premium profile make renting appealing, yet the rules, licenses, and setup steps can feel complex. In this guide, you will learn exactly what Key Biscayne requires, how state licensing and taxes work, what to expect from seasonality, and how full-service management streamlines the process. Let’s dive in.
Know the Key Biscayne rules first
Key Biscayne allows vacation and short-term rentals, but the Village sets a clear baseline: the minimum rental period is 15 continuous days unless your condominium documents state a different minimum. You must also secure three local items before you host your first guest: a Village Business Tax Receipt, a Certificate of Use, and a Key Biscayne Fire inspection. The Village lists startup fees as Certificate of Use $120, Fire inspection $75, and an annual Business Tax Receipt of about $115.76, for a total near $310.76. Review the full process on the Village’s short-term rental page, including required documentation and written lease provisions, such as having leases available for inspection and including Village language where required. You can find those details on the Village’s page for short-term rentals in Key Biscayne.
State license and taxes you must plan for
DBPR vacation rental license
Florida’s Department of Business and Professional Regulation treats many short stays as regulated vacation rentals. If you rent your whole unit more than three times per calendar year for periods of less than 30 days, or you advertise it as transient, you generally need a state license. The DBPR issues licenses for Vacation Rental — Condominium and Vacation Rental — Dwelling. Apply online and review definitions on the state site for DBPR vacation rental licensing. You still need to follow Village rules and your condo’s rules. The state license does not replace local approvals.
Lodging and sales taxes
Short-term rentals in Key Biscayne typically collect and remit several taxes. Expect Florida’s 6% state sales tax, Miami-Dade County’s local transient rental taxes of 6% for most of the county, plus the applicable county discretionary sales surtax. The combined total commonly lands around 13% in many Miami-Dade areas, but you should verify your exact rate using the Department of Revenue’s tables. See the state’s local transient rental tax chart and discretionary sales surtax information.
Who remits what
Some platforms may collect and remit certain state or county taxes on your behalf. Even so, you are responsible for correct registration, collection, and filing. Check current platform notices against the Florida Department of Revenue guidance so you do not miss a tax you must remit directly.
Your condo rules and local enforcement
Condominium documents can be more restrictive than the Village’s minimum. They may set different minimum-stay rules, require tenant registrations, limit parking, or restrict short-term rentals entirely. Always get written confirmation from your building that your rental plan is allowed and follow any association procedures.
The Village has increased enforcement. Local reporting notes that Key Biscayne is using listing-scraping tools to identify noncompliant properties and issue warnings and fines. If you plan to operate, register properly from day one. For context, see coverage on the Village’s efforts to crack down on rogue short-term rentals.
Is your property a good fit for multi-week rentals?
Key Biscayne is a small, high-value island with limited supply and premium pricing. Public trackers have reported median sale prices near $1.3 million in early 2026, reflecting the market’s upscale profile. Limited nightly supply and strong winter demand often support higher average daily rates for well-presented rentals.
Seasonality and demand drivers
Peak season runs roughly December through April. Travelers escaping colder climates and families visiting during holidays and school breaks lift occupancy and rates during these months. In the warmer months and during hurricane season, demand typically softens. For a visitor overview and timing insight, see Visit Florida’s Key Biscayne guidance.

Step-by-step launch plan
1) Legal and compliance setup
- Get written HOA or condo approval confirming your intended rental length and process.
- Apply for your state license if your plan meets the DBPR vacation rental definition. Start with the DBPR vacation rental guide.
- Apply with the Village for your Business Tax Receipt and Certificate of Use, and schedule the Fire inspection. Details and fee schedule are on the Village short-term rentals page.
- Register for state sales tax and Miami-Dade transient tax accounts, then confirm what your chosen platforms remit versus what you must file.
- Prepare written leases or occupancy agreements that include any Village-required language and your building’s rules. Keep copies available for inspection.
- Verify insurance coverage for coastal risks and rental use. Confirm homeowner, liability, flood, wind, and hurricane coverage with your carrier.
2) Guest-ready operations
- Provide a 24/7 local contact for guests and emergencies, as required by local codes. The Village outlines responsibilities on its site.
- Publish occupancy and parking rules that match your building and local guidance. Miami-Dade’s page on residential short-term vacation rentals offers useful context.
- Meet fire and life-safety standards, including smoke and CO detectors and fire extinguishers. You will have a scheduled Fire inspection through the Village.
- Build a reliable local vendor roster for housekeeping, linens, AC service, and urgent repairs, especially during peak season and holidays.
3) Pricing, minimum stays, and distribution
- Align your calendar with the 15-day Village minimum and your condo’s rules. If your association allows shorter stays, confirm how that interacts with Village standards.
- Use dynamic pricing that reflects seasonality and major Miami events, within your permitted minimum stay.
- Choose booking channels that fit your stay length and tax setup, and consider a direct-booking option for repeat guests.

Hurricane season prep
Key Biscayne sits on the coast, so seasonal planning is essential. Atlantic hurricane season runs June 1 through November 30, per the National Hurricane Center. Keep shutters or impact glass maintained per your building requirements, store a basic hurricane kit at the property, and document a secure lock-up and re-opening checklist with your local manager. For official season dates and resources, reference the National Hurricane Center’s tropical cyclone climatology.
Why local management matters on the island
Key Biscayne’s island setting and condo-driven rules make local expertise a real advantage. A capable on-island manager coordinates DBPR and Village onboarding, optimizes your listing and pricing, manages guest communication, oversees 24/7 response, schedules housekeeping, and maintains vendor relationships that keep your home in top shape. In a market with active enforcement, that same oversight reduces compliance risk and protects reviews, repeat bookings, and asset value.
