If you want to check maritime zone property in Costa Rica, you need to understand one fundamental rule before you do anything else: land within 200 meters of the ocean is almost never privately owned. It’s governed by the Ley de la Zona Marítimo Terrestre (Maritime Zone Law, Law 6043), and the legal framework here is nothing like what US or Canadian buyers are used to. The first 50 meters from the high-tide line is public land, full stop. No one can own it. The next 150 meters is the “restricted zone,” where land is held through a municipal concession, not a title deed. Buying in this zone without understanding that distinction has cost foreign buyers serious money. Don’t let it cost you.
- Land within 200 meters of the Costa Rica coastline is subject to the Maritime Zone Law and is almost never freehold titled property.
- Concession rights (not ownership) govern the restricted zone. They can be revoked, expire, or transfer with conditions.
- Always verify the finca number, concession status, and municipal records before placing any deposit.
- Foreign nationals who have not lived in Costa Rica for at least five years cannot hold a maritime zone concession directly in their name.
What Is the Maritime Zone and Why Does It Matter to Buyers?
The Maritime Zone (Zona Marítimo Terrestre, or ZMT) covers a 200-meter strip running along both the Pacific and Caribbean coasts. Think of it as a two-layer system. The first 50 meters inland from the mean high-tide mark is called the zona pública (public zone). Structures here are technically illegal, full stop, even if something has been sitting there for decades.
The next 150 meters is the zona restringida (restricted zone). This is where most beachfront hotels, vacation rentals, and homes actually sit. Property here is held via a concession granted by the local municipality, not through a fee-simple title registered with the Registro Nacional. That’s a critical difference. A concession is a long-term permit with conditions. It can be renewed, revoked, or transferred, but it does not behave like ownership the way you’d expect back home.
Beyond 200 meters, you’re outside the ZMT and can hold titled property normally. Plenty of great beachfront communities, like those around Tamarindo, Nosara, and Uvita, have a mix of concession and titled land sitting side by side. Knowing which you’re looking at before you make an offer is non-negotiable.
How Do You Actually Check Maritime Zone Property in Costa Rica?
Start with the finca number. Every registered property in Costa Rica has a finca (property registry number). If a seller can’t give you a finca number, that’s your first red flag. With the finca, you or your attorney can look up the property in the Registro Nacional and see what type of right is registered: titled ownership, a concession, or nothing at all.
The fastest way to get an immediate picture is to run a property check on Folio. The free map shows the finca and maritime-zone flag within minutes, and the $29 report pulls live registry data on the registered owner, liens and annotations into one readable report. Neither replaces a full legal due-diligence process, but together they tell you whether the property is titled or concession, and whether there are red flags that need attorney attention. Do this before you have any money-on-the-table conversations.
After the Folio check, you’ll want to go deeper. Concession properties require you to also review municipal records at the local municipalidad, since the municipality (not the Registro Nacional) administers concession grants. The municipality holds the concession file, payment history of canon fees, and any violations or complaints against the concession.
Can Foreigners Hold a Concession in the Maritime Zone?
This is the question that surprises buyers most. Foreign nationals who have not been legal residents of Costa Rica for at least five consecutive years cannot hold a maritime zone concession in their own name. That’s the law, and it’s enforced.
What most foreign buyers do instead is hold the concession through a Costa Rican corporation (sociedad anónima, or S.A.). This is legal and widely used, but the corporation must have Costa Rican shareholders holding at least 50% of the shares if the concession is in the restricted zone, depending on the specific municipal bylaws and applicable regulations. Get your attorney to confirm the shareholder structure before you buy into an existing S.A. that holds a concession.
Some municipalities have a reglamento de la zona marítima terrestre (their own ZMT regulation) that adds local requirements on top of the national law. Osa, Santa Cruz, Carrillo, and other coastal municipalities each have their own rules. Don’t assume that what’s allowed in Guanacaste works the same in the Southern Zone.
What Are the Key Documents to Verify for Maritime Zone Property?
| Document | What It Confirms | Where to Get It |
|---|---|---|
| Finca registration | Registered owner, liens, annotations, property type | Registro Nacional / Folio |
| Concession contract | Duration, canon fees, permitted use, conditions | Local municipality |
| Plano catastrado | Surveyed boundaries, area, cadastral number | Registro Nacional / Catastro |
| Canon payment receipts | Confirms concession is current, no arrears | Municipality records |
| ICT approval (if applicable) | Tourism-zone use authorization | ICT regional office |
| Environmental permit | SETENA approval for development or construction | SETENA |
Every one of these documents matters. Buyers who skip the concession contract review are the ones who discover later that the canon (annual fee paid to the municipality for use of concession land) is in arrears, or that the permitted use doesn’t allow short-term rentals. Canon arrears can be grounds for concession revocation.
What Are the Biggest Mistakes Buyers Make With Maritime Zone Property?
The mistake we see most is treating a concession like a title. A concession has an expiration date, typically granted in periods of up to 20 years and renewable. If you buy into a concession that has five years left with no renewal in process, you’re buying a time-limited right, not real property. That drastically affects the property’s value and your ability to finance or resell it.
Second mistake: not checking whether construction on the property has environmental approval from SETENA. Beachfront development in Costa Rica requires environmental impact assessment before building permits can be issued legally. If a structure was built without proper SETENA clearance, you inherit that liability.
Third: relying only on a visual inspection and the seller’s word. One of our clients almost bought a beautiful property in the Osa Peninsula where the main structure was partly inside the 50-meter public zone. You can’t see that by walking the land. Only a proper survey aligned against the legal high-tide mark will tell you. That’s exactly the kind of boundary problem a property verification report can flag, pointing you toward the right follow-up questions before you spend anything.
How Does Buying Maritime Zone Property Affect Rental Income Potential?
Beachfront concession properties can absolutely generate strong rental income. The Guanacaste coast, the Southern Pacific around Dominical and Uvita, and the Nicoya Peninsula all have active vacation rental markets. The concession itself doesn’t prevent you from renting, but the concession contract specifies what uses are permitted. Some concessions are granted for residential use only. Operating a vacation rental on a residential-use concession could put the concession at risk.
If rental income is part of your plan, confirm the permitted use before buying and factor in the cost structure accurately. Use the REG rental ROI calculator to model realistic returns once you have the canon fee, property taxes, and management costs in front of you.

Frequently Asked Questions
Is concession property in Costa Rica safe to buy?
Yes, with proper due diligence. Many thousands of legitimate properties along the Costa Rican coast are held via concession, including established hotels, rental homes, and residences. The key is verifying the concession is current, properly registered with the municipality, and in compliance with its conditions. A concession with a good renewal track record and no violations is a legitimate and commonly transacted right.
How do I find out if a property is in the maritime zone?
Start by running the finca number through the Registro Nacional or ordering Folio’s $29 report to pull the registry record. The property type and any maritime-zone annotations will show up there. For a precise boundary determination, you need a licensed topographer (topógrafo) to survey the parcel against the mean high-tide mark. The municipality can also show you their ZMT cadastral maps for the area.
Can a US citizen own beachfront property in Costa Rica?
US citizens can own titled property in Costa Rica with the same rights as Costa Rican nationals, with one important exception: they cannot hold a maritime zone concession directly in their own name unless they’ve been legal residents for at least five years. In practice, most foreign buyers hold concession property through a Costa Rican corporation. This is a normal and accepted structure, but it must be set up correctly with proper shareholder ratios.
What is a canon payment in the maritime zone?
A canon is the annual fee you pay to the municipality for the right to occupy and use your concession land. Think of it as a recurring ground rent. The amount is set by the municipality based on a valuation of the property. If a seller has unpaid canon fees, those arrears don’t disappear at closing. Confirm the payment history is clean before you sign anything.
What happens if a maritime zone concession expires?
An expired concession that isn’t renewed puts your right to occupy the land in jeopardy. The municipality can deny renewal if the concession has violations, if the property hasn’t been developed per the approved plan, or if there are canon arrears. Always check how many years remain on a concession and whether a renewal application has been filed. If you’re buying with less than five years remaining and no renewal in progress, negotiate accordingly or walk away.
