STR Regulations for Marathon, Florida

Overview: Are Short-Term Rentals Allowed in Marathon, FL?

Yes, short-term rentals (STRs) are explicitly allowed in Marathon, Florida, but are heavily regulated. The City of Marathon permits licensed vacation rentals for stays of 7 to 28 nights; rentals for fewer than 7 nights are prohibited. The City requires licenses for property owners and agents, mandatory training, fire inspections, and compliance with local and state regulations. While Monroe County governs unincorporated areas, Marathon is an incorporated city with its own STR framework. Investors must comply with both City of Marathon regulations (for properties within city limits) and Monroe County rules (for surrounding unincorporated areas). This guide prioritizes City of Marathon requirements, followed by County rules for context.

How to Start an STR Business in Marathon, FL

  1. Zoning Verification: Confirm your property is in an area where STRs are permitted. Within Marathon city limits, zoning dictates STR rules.

  4. Fire & Life Safety Inspection: Schedule and pass an inspection by the Monroe County Fire Marshal's Office for each property (required for both initial permits and renewals). Fees vary by bedroom count.

  6. Comply with State Regulations: Register with Florida State for taxes (Sales Tax, Tourist Development Tax) and lodging compliance (see State Regulations section).
  7. Advertising Compliance: Crucial: All advertisements must reflect a minimum 28-day stay requirement for county properties and the City license number (Property License - PLR and Agent License numbers must be displayed prominently). Renting for < 7 days is illegal in the City.
