Marathon Airbnb Rules & Investment Guide (2026)

A Marathon purchase should pass City licensing, rental-term, occupancy, parking, tax, insurance, and title checks before projected revenue enters the decision.

• Confirm the parcel is inside the City of Marathon and that each dwelling intended for vacation rental is legally existing.
• Model a minimum stay of seven nights; the City ordinance prohibits renting a private residence for fewer than seven nights.
• Budget for the City Vacation Rental Property License, annual renewal, required training or a licensed agent, and separate County and State obligations.
• Test whether the site can support the guest count, vehicles, boats, and trailers without exceeding the property-specific parking and dock limits.
• Review flood exposure, wind coverage, evacuation planning, seawall or dock condition, deed restrictions, and association rules before committing capital.

The City license applies to legally existing dwelling units offered for stays from seven through 28 nights.

• Verify the street address in the City's online vacation-rental license search and compare the record with the parcel and dwelling proposed for purchase.
• Ask City Planning whether the dwelling and any accessory units are legal and whether open permits, code cases, or nonconforming conditions affect licensing.
• A separate Vacation Rental Property License is required for each dwelling used as a vacation rental when a parcel contains more than one legal dwelling.
• Do not underwrite nightly or weekend stays: renting a private residence for fewer than seven nights is prohibited by the City ordinance.
• Check deed, condominium, homeowners-association, and mortgage restrictions because private rules may be stricter than City law.

Operation requires an annual City Vacation Rental Property License plus owner training or management by a licensed vacation-rental agent, with fees tied to bedroom count.

• Apply through the City's ViewPointCloud vacation-rental application portal before advertising or accepting guests.
• Complete the City vacation-rental training and obtain the certificate, or contract with a person who holds a valid Vacation Rental Agent License.
• Renew annually and submit the renewal application at least 30 days before expiration; a delinquent license becomes void.
• Use the City's current fee schedule when budgeting: Resolution 2026-05 lists new-license fees from $1,200 for one bedroom and annual-renewal fees from $850 for one bedroom, with higher amounts as bedroom count increases.
• Place the property-license number and agent-license number on every advertisement; internet advertising must show the PLR number on the listing home page.
• Maintain access for authorized City inspections and keep the license, tenant records, parking information, and required notices current.

Guest capacity is constrained by fire and building codes, bedroom count, parking, and waterfront conditions.

• Maximum overnight tenant occupancy is two people per bedroom plus two people, unless the City approves a higher limit under the ordinance.
• Before 7 a.m. or dawn, whichever is earlier, and after 10 p.m., occupancy may not exceed the permitted overnight count.
• Provide off-street or otherwise lawful parking for every guest vehicle, watercraft, and trailer; verify the approved space count before setting capacity.
• For waterfront property, confirm dock dimensions and navigation clearance; docked vessels may not be rafted together or create a navigation hazard.
• Use a written lease that binds the tenant and all occupants to the City restrictions and permits termination or eviction for violations.

A registered local contact must be reachable around the clock and able to respond promptly to complaints.

• Register the contact name and telephone number with the City and keep that information available to guests and enforcement personnel.
• The licensee or agent must be available 24 hours a day, seven days a week, and respond to complaints within one hour, on site if necessary.
• Keep a tenant roster with occupant count and the number, make, and model of guest vehicles available for City or Sheriff review.
• Post or provide the permitted occupancy, vehicle limit, parking plan, trash schedule, local-contact number, and violation consequences.
• Create operating procedures for noise, trash, parking, boats, storm preparation, cleaning, maintenance, and documented complaint responses.

Short stays require Florida sales and use tax registration, Monroe County tourist-tax registration, and local business-tax compliance.

• Monroe County lists a local business tax receipt as required for all rental properties, regardless of rental duration.
• Rentals for six months or less require a Monroe County tourist development tax account and Florida sales and use tax registration.
• Rentals for less than 30 days or one month also require the applicable Florida DBPR state license.
• Monroe County tourist development tax is 5% of gross rental revenue and applies to mandatory guest charges such as cleaning, pet, processing, and resort fees.
• The County states that online platforms do not remit its 5% tourist development tax; owners must ensure filing and payment, including zero-activity returns when required.

Unresolved guest conduct and repeated violations can produce daily fines, suspension, or revocation.

• City rules prohibit unnecessary noise disturbances during protected hours and require the licensee or agent to resolve complaints promptly.
• A violation may be fined up to $500 per day, per unit, per violation.
• Three violations within 12 months can suspend the property license for 12 months; repeat history can lead to revocation.
• Advertising or renting while a license is suspended or revoked can trigger a license revocation period of at least 60 months.
• Keep dated records of complaints, calls, site visits, corrective action, guest notices, and any enforcement correspondence.

Tie every underwriting assumption to a parcel record, license record, written rule, quote, or inspection.

• Confirm parcel boundaries, legal dwelling count, bedroom count, open permits, code cases, prior license history, and current City license status.
• Obtain written insurance quotes for wind, flood, liability, loss of income, watercraft exposure, pool exposure, and commercial short-term-rental use.
• Inspect roof, shutters or impact openings, electrical and life-safety systems, drainage, seawall, dock, lifts, wastewater systems, and salt-corrosion exposure.
• Review association rules, recorded restrictions, pending assessments, lender conditions, and any rental-management agreement.
• Model revenue only after subtracting taxes, platform costs, cleaning, utilities, landscaping, pest control, repairs, reserves, insurance, management, and financing.

Use the City, County Tax Collector, State regulators, and recorded property documents to close parcel-specific gaps.

• City of Marathon Vacation Rentals: licensing guidance, training, applications, compliance information, and the public license search.
• Marathon ViewPointCloud search: check an address for a vacation-rental license and available owner or local-contact information.
• Monroe County Tax Collector rental requirements: business-tax, tourist-tax, sales-tax, and DBPR registration sequence.
• Florida DBPR vacation-rental guide: state licensing classifications and application guidance.
• Before closing, request a City planning and code review, insurance quotes, a title and restriction review, and inspections tailored to coastal structures.

For a parcel-specific feasibility review, plan a Marathon property strategy call before committing capital.
