"I'm convinced a lot of our housing issues are because we have about 1,400 vacation rentals in this town that locals can't live in."

That was Marathon City Councilman Kenny Matlock, speaking at a March 2026 council meeting where the city voted to raise vacation rental license fees for the fifth time since state law preempted broader control in 2011. It's a striking line, and on its face it sounds like the setup for a crackdown. It isn't. Marathon cannot cap the number of vacation rentals in the city, cannot limit how often they turn over, and cannot restrict their duration below what a 2011 state law already locked in. All the city can do is charge more for a license that will keep existing no matter what the council decides.

If you're evaluating Marathon as a place to hold an investment property, that distinction is the whole ballgame. The regulatory risk here doesn't look like the risk in Key West, where a finite, transferable license is itself a scarce asset with its own resale value. In Marathon, the license is closer to a recurring bill the city adjusts as its own costs rise. Understanding which kind of asset you're actually buying changes how you should underwrite the deal.

The Law Marathon Can't Get Around

Florida passed a preemption law in 2011 that strips municipalities of the ability to prohibit or regulate the duration and frequency of short-term rentals, with one exception: ordinances already on the books before June 1, 2011 are grandfathered in. Marathon's seven-night minimum stay survives because it predates that cutoff. But the number of licenses the city issues, and how often a licensed property changes guests, are off the table for further restriction.

That statute has held up through multiple challenges to loosen it further and one attempt to tighten it. In 2024, state lawmakers considered Senate Bill 280 and House Bill 1537, which would have centralized short-term rental regulation under the Florida Department of Business and Professional Regulation and reduced local control even more than the 2011 law already had. SB 280 was vetoed in June 2024, so the framework Marathon operates under today is the same one it has worked within for over a decade. City Attorney Steve Williams has told the council directly that pushing the ordinance too far in either direction risks losing local control entirely and defaulting to sparser state enforcement, which is part of why every fee increase since 2011 has been argued as cost recovery rather than policy.

What a License Actually Costs Right Now

Because a cap isn't legally available, fees are the only dial the city can turn. Here's how that dial has moved:

The January proposal is worth pausing on, because it's the number that would have made headlines if it had passed. City staff projected the full $1,000 increase would generate roughly $1.23 million for the general fund, cutting Marathon's planned deficit spending by more than half. That's not what happened. After a public hearing that drew a dozen rental owners, managers, and industry professionals pushing back on doubling their fees overnight, the council tabled the resolution and came back in March with an increase roughly a tenth the size of what was proposed. If you've seen the $1.23 million figure attached to Marathon's rental fees anywhere, it describes a plan that never took effect.

The Math That Didn't Add Up

The council's own numbers are what make this interesting for anyone underwriting a rental property here. Arguing against folding fire and EMS costs into the fee increase, Councilman Lynn Landry pointed out that vacation rentals make up 18% of Marathon's single-family homes but accounted for only 5% of the city's emergency calls over the past year. If vacation rentals were straining city services in proportion to how many of them exist, you'd expect their share of emergency calls to track closer to their 18% share of the housing stock. It doesn't. The gap suggests the service-burden argument for higher fees is weaker than it sounds in a council chamber, even though the fees keep rising anyway.

That doesn't mean the fee increases are unjustified. It means the actual friction, per Matlock's own framing, isn't rentals straining fire trucks and lifeguards. It's rentals occupying housing stock that could otherwise support full-time residents. That's a land-use argument, not a service-cost argument, and the city has settled on fees as its proxy for addressing it because fees are the one lever the state hasn't taken away.

What This Means for the Numbers You Run

If you're comparing Marathon to a market like Key West, where transient rental licenses are capped and a good one can be worth real money on its own, recalibrate what you're pricing in. A Marathon vacation rental license isn't an appreciating asset you're competing for. It's an annual operating line that has moved upward five times since the 2011 crackdown, most recently by $100 to $200, with a much larger increase publicly considered and only narrowly avoided.

Build that into your holding-cost assumptions the way you would a rising insurance premium: not alarming in any single year, but a line worth stress-testing against a decade, not a quarter. The council has signaled it will keep the fee schedule under review with a third-party cost study now underway, which means this isn't a one-time adjustment. It's a standing process.

Reading Today's Market While You Decide

The current market gives you a real contrast to sit with. Over the three months ending June 2026, Marathon's median sale price rose 43.4% year over year to $1.0 million, even as the median sale price per square foot fell 11.2% to $686 over that same window. Those two numbers moving in opposite directions usually mean one thing: larger and higher-end properties are making up more of what's selling, pulling the headline median up, while the actual cost of square footage across the broader market is easing rather than tightening.

Homes were selling after a median of 99 days on market in that period, down slightly from 106 days the year before, but active inventory measured against recent sales pace still points to roughly 14 months of supply as of this writing, well above the 3 to 6 month range considered a balanced market. Read together, that's a market where price headlines look like a seller's story and time-on-market looks like a buyer's story. For an investor, that combination is worth sitting with before you anchor to the first number you see. A property that's been sitting for close to 100 days in a market with that much supply on hand is a different negotiation than the median price alone suggests.

Frequently Asked Questions

Can Marathon add a cap on the total number of vacation rentals in the future? Not under current state law. Florida's 2011 preemption statute prevents local governments from capping the number, duration, or frequency of short-term rentals unless the restriction predates June 1, 2011. Marathon's seven-night minimum stay survives because it's grandfathered in. A new cap would not be.

Is the seven-night minimum stay still enforced? Yes, and it's one of the few restrictions the city has been able to keep specifically because it predates the 2011 cutoff. City staff have cautioned the council that pushing the ordinance too far in other directions risks losing that provision along with local enforcement authority.

Will vacation rental fees keep going up? The council has directed staff to complete a third-party study comparing the city's fees to its actual costs, which suggests further adjustment is likely rather than settled. Whether the next change looks like the modest March 2026 increase or the larger proposal that was tabled in January will depend on what that study finds and how the council weighs it against community pushback.
