In April 2026, Cabo Rojo raised the annual fee for the municipal certification on each short-term rental unit from $250 to $500. The charge is nonrefundable and isn't prorated. If a building rents its rooms or apartments separately, each one pays its own fee. A transition clause kept the $250 rate for owners who had already filed their fiscal 2025-2026 application before the ordinance was approved. Anyone who hadn't filed or paid by June 30, 2026 falls under the $500 rate. Over the same period, the market data shows the average Cabo Rojo listing earning about a third more than a year earlier. Taken together, those two facts look like good news that easily covers a small new cost. Run the numbers per available night and the picture changes. For anyone buying in Boquerón, Joyuda, Combate or Puerto Real with a rental plan, the fee turns into a question about how many nights the property can realistically be open.
The $500 is charged per unit, not per property
The fee comes from Ordinance 37, Series 2025-2026, which amended the town's 2022 lodging ordinance. The Municipal Legislature passed it 13 to 0 on April 13, 2026, and the mayor signed it on April 16. The ordinance covers any stay of 90 days or less. Its definition of "lodging" is broad: houses, apartments, cabins, villas, campers, containers, boats, and any part of a property rented on those terms.
Three details matter most once you own the property.
- Each door is billed separately. A house rented as one unit pays once. A house with a main unit and a separately rented studio pays twice.
- The fee follows the fiscal year, not your start date. It covers the current July-to-June fiscal year, or whatever is left of it, and it isn't prorated. Someone who starts renting in February pays the full $500 for the few months left before June 30.
- The application comes before the first guest. The municipality's lodging certification page says owners and operators must notify the Finance Department and pay before the rental activity begins.
The calendar is fixed. Invoices go out by April 30, and payment is due by June 30. Paying before June 1 earns a 5% discount. A payment made between June 1 and June 30 is still on time, but it doesn't get the discount. From July 1, an unpaid charge accrues 12% annual interest plus a 10% surcharge. Today is October 12, 2026, so the next billing cycle runs through spring 2027. Anyone who closes on a rental this fall and lists it right away falls under the before-the-first-guest rule.
The ordinance's own preamble describes $500 as roughly $41.66 a month for a unit "that can be rented every day of the year." That every-day assumption is exactly what the market data calls into question.
Fewer listings, the same value per night
AirDNA's Cabo Rojo overview, updated October 6, 2026, covers the 12 months from September 2025 to September 2026.
| Metric, trailing 12 months to Sept. 2026 | Value | Change vs. prior year |
|---|---|---|
| Active listings | 468 | down 23.7% |
| Average annual revenue per listing | $26.9K | up 35.3% |
| Occupancy | 45% | up 10.9% |
| Average daily rate | $184 | down 8.6% |
| RevPAR | $83 | up 1.2% |
RevPAR is the figure that measures what a night is worth. AirDNA defines it as occupancy multiplied by average daily rate and calls it the truest measure of earning power per available night. It rose 1.2%. Occupancy went up, but guests paid less per booked night, and the two changes nearly canceled out.
Average revenue per listing still rose by a third. AirDNA doesn't explain the gap, and its figures can't settle the cause. The revenue figure includes cleaning and other guest fees and is calculated before host expenses, so it doesn't measure the same thing as RevPAR. Even so, annual revenue is roughly earnings per available night multiplied by available nights. With the first number nearly flat, one reading that fits the arithmetic is that the average listing still counted was open on more nights than a year earlier.
That reading also fits the listing count. Nearly a quarter of active listings dropped out of the count in a year. The data doesn't say who left. If the listings that dropped out had shorter calendars, the average for the listings that stayed would rise even if no individual host changed anything. The figures are consistent with that kind of shift in the group being averaged, but they don't prove it, and higher guest fees could account for part of the gain.
Why a flat fee hits part-time calendars harder
Cabo Rojo has had a lot of part-time hosts. A News is my Business report on Airbnb's 2024 data listed Cabo Rojo among the municipalities with the highest concentration of occasional hosts, defined as hosts who list for fewer than 120 days a year.
A fixed fee costs the same whether the calendar is open for 60 nights or 300. At the market's $83 RevPAR, $500 equals about six available nights of earnings. Over a 300-night calendar, that is a small slice. For a family that rents its Boquerón place only around its own visits, it takes a noticeably larger share, and for a separately rented second unit it applies all over again. At the town's $41.66-a-month framing, the cost is the same every month whether the unit is booked or sitting empty.
None of this shows that the fee caused the drop in listings. The fee rose in April 2026, and the listing decline covers a 12-month window that began well before then. The two happened in the same period. A flat per-unit fee and a flat RevPAR both work out better for a unit that's open for booking most of the year.
The paperwork behind one certificate
The certificate is the last step in a chain of island and municipal registrations, and a buyer's timeline has to allow for every one of them. Ordinance 37 lists these application requirements, among others:
- Photos of both sides, the front, the back and the interior of the unit
- A Merchant Registry (Registro de Comerciante) and a provisional or current municipal patente
- A certification of IVU sales-and-use-tax debt status from Hacienda
- The property's cadastre (catastro) number
- Proof of title or the right to operate, such as a deed or lease
- A use or operation permit, if one has been issued
- The hotel number assigned by the Puerto Rico Tourism Company
The last item connects the municipal process to the island-wide one. According to the Tourism Company's room tax guidance, stays under 90 consecutive days fall under Act 272-2003. Hosts register as innkeepers, collect a 7% room-occupancy tax, and file monthly declarations by the 10th of the following month. Cabo Rojo's certification sits on top of that registration and doesn't replace it.
The ordinance also gives the arrangement a neighborhood obligation. Owners, operators and intermediaries are responsible for making sure guests don't affect the quality of life of neighbors. It also offers something back. Hosts who are registered and current on the fee can consent in writing to have the municipality promote their rental through its official tourism activities.
There is one exclusion. The municipality's summary describes it as covering a lodging that is the principal residence of its owner or family, limited to one unit. Ordinance 37 says the claim must be supported with a deed, lease or similar document plus a sworn statement that the property is the owner's principal residence. If Finance denies an exclusion, the owner has 20 days from the mailing date of the notice to seek judicial review.
Where enforcement and the island-wide bill stand
Pressure for enforcement is coming partly from within the local lodging industry. In October 2026, Ey Boricua reported that the owner of Parador Boquemar in Boquerón asked the government for stricter oversight of short-term rentals. He said he doesn't oppose the model, and that "the main problem is that they aren't validated," referring to existing laws and regulations. The statement didn't propose specific measures and didn't include figures on rentals in the west.
At the island level, Senate Bill 238 would require municipal short-term rental registries and annual licenses. NotiCel reported proposed fees of $100 for shared residences and $500 for non-shared ones. The version reviewed by the Legislature's budget office, OPAL, would also raise the lodging tax from 7% to 8%, with the extra point going to municipalities. Metro Puerto Rico reported that the Senate approved the bill in November 2025 and sent it to the House. We found no record that it has become law. Any rental projection that depends on it should treat it as pending.
Questions to settle before you close
Does the seller's certification carry over to me? The ordinance places the duty to apply and pay on each owner or operator before rental activity begins. Ask the seller for certification receipts and the property's Tourism Company hotel number, and confirm the new owner's filing with the Cabo Rojo Finance Department.
How should I read a seller's revenue history? Ask how many nights the calendar was open, not just what it earned. In a market where RevPAR rose 1.2% over the 12 months to September 2026, revenue growth that depended on adding open nights says more about the previous owner's schedule than about the property.
Are these market figures official? No. AirDNA's numbers are commercial estimates. They count de-duplicated listings across Airbnb, Vrbo and Booking.com and refresh monthly. They show the overall direction of the market, not how a specific address will perform.
What if I plan to rent only a few weeks a year? The $500 is the same at any calendar length, unless the principal-residence exclusion applies. Divide the fee, the room-tax filings and the registration steps by the nights you actually expect to open, not by 365.
