Costa Rica Maritime Zone (ZMT) Explained: Titled Property, Concession, and Possession Rights

Walk into a Costa Rica real estate conversation and the word 'beachfront' gets used like it means one thing. It does not. The first 200 meters inland from the mean high tide line of every coast in Costa Rica sits under a separate legal regime from the rest of the country — Ley 6043, the Ley sobre la Zona Marítimo Terrestre, passed in 1977. That law changes what you can actually buy, what a foreigner is allowed to hold, and what happens to the asset after you close.

For US and Canadian buyers, this is the single biggest structural difference in Costa Rican coastal property. Fee-simple ownership — the kind of title you take for granted back home — is the exception on the coast, not the rule. Most 'beachfront' property for sale is held under a municipal concession. Some of it is held under something called 'possession rights' that look like ownership and are not. This is the guide I give buyers in Dominical, Uvita, and Ojochal before they write an offer anywhere near the coast.

The 200-Meter Rule, in Plain English

Every square meter of the first 200 meters inland from the mean high tide line, around the entire country, is defined as the Zona Marítimo Terrestre — the Maritime Terrestrial Zone, or ZMT.

That strip is split in two. The first 50 meters is the *zona pública*. It is public. It cannot be privately owned, sold, leased, or concessioned. You cannot build on it. You cannot fence it off. It belongs to the state and must stay open for public access — Articles 9 and 10 of Ley 6043 make this absolute. If someone tries to sell you something inside those first 50 meters, walk away.

The next 150 meters is the *zona restringida* — the restricted zone. This band cannot be held as titled fee-simple property under normal circumstances. It can only be held through a *concesión* — a lease granted by the local municipality and approved by the Costa Rican Tourism Board (ICT).

That second band — those 150 meters of restricted zone — is where the real market lives. Almost every beach-adjacent commercial building, every beachfront cabina, every beach hotel in a town like Dominical or Uvita exists under a concession, not under title.

       Mean high tide line                   200 m inland

Everything from the 200-meter mark inland is standard titled land governed by the Civil Code, like anywhere else in the country. A ridge-top ocean view home sitting 300 meters back from the water is normal fee-simple property — you own it, you record it in the Registro Nacional, and a foreigner can hold it 100% in their own name with no residency required. That is how the vast majority of Costa Ballena and Southern Zone ocean view properties are actually held.

The Three Ways Costa Rica Coastal Property Is Held

Once you understand the 200-meter rule, the three tenure types buyers encounter make sense.

1. Titled property (fee simple, *propiedad titulada*)

This is the ownership regime most US and Canadian buyers understand. Full ownership, registered in the Registro Nacional de la Propiedad, with a *folio real* number you can look up. The property is held under the Civil Code. You can hold it in your own name as a foreigner with no residency requirement. You can mortgage it, insure it, and sell it like any other real estate.

Almost all inland property and almost everything on the Southern Zone's view ridges — Dominicalito ridge, Escaleras, Hatillo, the hills above Uvita, the Ojochal canyons — is standard titled land. Our Front Row Titled Oceanfront Hotel in Drake Bay is one of the uncommon cases of a *titled* coastal asset in the Southern Zone — the exception, not the rule.

2. Registered concession (*concesión en la ZMT*)

This is the only legal way to hold the restricted 150-meter band under Ley 6043. A concession is a formal lease granted by the local municipality, approved by the ICT, and registered in a specific concession registry (not the regular property registry). You pay an annual fee — the *canon* — set by the municipality against the property's current Ministry of Finance valuation.

A registered concession is a real legal instrument with defined terms and defined rights. It is also time-limited, conditional on continued compliance, and foreigner-restricted. More on all of that below.

3. 'Possession rights' (*derechos de posesión*)

This is where many foreign buyers get hurt. 'Possession rights' is a loose term for someone's claim to occupy land without registered title and without a formal concession. Inland, in some rural contexts, possession can eventually ripen into title through a lengthy process. In the ZMT, it does not. The state owns the land, the state cannot lose title through adverse possession, and a long history of occupation does not convert into anything you can legally sell, mortgage, or insure. Yet these 'rights' are routinely offered for sale, sometimes with a handwritten document and decades of occupation as 'proof.' Inside the ZMT, they are a liability dressed up as an asset.

Titled vs Concession vs Possession: Side by Side

What a Concession Actually Gives You

A concession is a right of use and enjoyment for a defined term. It is not ownership. The municipality grants it; the ICT approves it; both sign off on what you can do with the land during the lease.

Under Article 48 of Ley 6043, concessions are granted for no less than five years and no more than twenty. Renewals are permitted under Article 50 — successively, for periods not exceeding the original — but each renewal requires the concessionaire to request it, the municipality to agree, and the ICT to approve. This is not automatic. A renewal application that lands at the wrong moment — during a plan regulador update, during a municipal dispute, during an audit — can get held.

You pay an annual *canon* to the municipality. The specific amount depends on the municipality's current rate and the Ministry of Finance's valuation of the parcel. The *canon* is not optional. Non-payment is cited in Ley 6043 as grounds for cancellation of the concession. There is no grace period you can count on.

What you can build is dictated by the coastal regulatory plan — the *plan regulador costero* — for that specific stretch of coast. Not national code. Not what your neighbor got away with. The plan regulador assigns each parcel a zoning use (tourism, residential, mixed, protected) and defines the maximum footprint, height, and density. If the plan regulador changes between your concession grant and your renewal, your build envelope can change with it.

Can Foreigners Hold a Costa Rica Beachfront Property Concession?

This is one of the most important questions for any US or Canadian buyer looking at the coast — and the answer has nuance that many sellers will not volunteer.

Article 47 of Ley 6043 sets the foreigner rules. A person without Costa Rican citizenship cannot hold a ZMT concession in their own name unless they have been a legal resident of Costa Rica for at least five years. Corporate holdings are similarly limited. A Costa Rican corporation that holds a concession must have at least 50% of its capital held by Costa Rican nationals. Foreign-domiciled entities cannot hold a concession at all.

In practice this means two realistic paths for a foreign buyer who does not yet have five years of residency: either partner with Costa Rican nationals who hold the controlling majority of the concession-holding entity (with all the risk that comes with being a minority holder of something you cannot vote control of), or wait until residency ripens and then hold it personally. Neither is simple. Both require a lawyer who does ZMT work regularly — not a general real estate attorney.

Some municipalities apply stricter interpretations. There have been documented cases of municipalities requiring 50% ownership by Costa Rican citizens by birth or naturalization specifically, which closes off even naturalized foreign-held majority stakes. The local rule matters more than the national one in day-to-day practice.

The Plan Regulador Costero: Why It Gates Everything

Every new concession, every concession renewal, and every building permit inside the ZMT ultimately depends on one document: the *plan regulador costero* — the coastal regulatory plan — approved for that section of coast.

The plan regulador is prepared by the municipality (with ICT and INVU input), goes through environmental review (SETENA), and once approved, sets the zoning map, allowed uses, and build envelopes for the ZMT in that sector. Without a current, approved plan regulador for a specific stretch of coast, new concessions generally cannot be granted and existing ones face limits on renewal and modification.

This is where buyers get hit with the gap between 'this is for sale' and 'this can actually be used.' A seller can show you a concession document that looks perfect, but if the plan regulador for that sector has expired, is under review, or is being contested, your intended use may not be approvable. New structures may be blocked outright. Existing structures may become harder to insure, refinance, or transfer.

In the Southern Zone — Osa canton, which includes Dominical, Uvita, Ojochal, and Costa Ballena — this gap is a real issue in 2026, which we cover below.

'Possession Rights' in the ZMT: Why Smart Buyers Walk Away

Some of the most dangerous deals offered to foreign buyers on the Costa Rica coast come packaged as *derechos de posesión* — possession rights — over land inside the ZMT.

The pitch usually goes something like this: 'My family has lived on this beachfront for forty years. We have proof of possession. We will sell you our possession rights. Later you can formalize a concession.' There is almost always a notarized document, a seller who is friendly and credible, and a price that looks like a deal relative to titled land nearby.

What that means in practice: you cannot register the asset in your name. You cannot get title insurance. You cannot pledge it for a mortgage. The municipality can cancel the occupation at any time, and structures in the public 50 meters can be ordered demolished with no recourse. If the parcel has value in a future concession, the state — not you — decides who gets to apply for it. This is the category where foreign buyers lose the most money in Costa Rica coastal real estate, usually not to outright fraud but to a well-meaning seller offering something they believe is valuable, bought by a buyer who did not understand what a 'possession right' in the ZMT actually is — or, more precisely, is not.

The Narrow Titled-Beachfront Exception

Yes, genuinely titled beachfront exists in Costa Rica. It is rare, it is heavily litigated, and it commands a premium.

Article 6 of Ley 6043 carves out two narrow exceptions. First, land inside INVU-declared urban coastal zones (*ciudades litorales*) can hold fee-simple title even if it falls within the 200 meters. Second, property that was validly registered before 1970 under earlier law (notably Ley 4558) can also hold fee-simple title inside the band, provided the registration has not been successfully challenged.

In practice both exceptions are narrow. Most towns in the Southern Zone are not formally declared urban coastal zones. Pre-1970 titled parcels exist but are a small subset, often with complicated histories. Any 'titled beachfront' claim should be independently verified by an attorney who runs a full title study — not relied on from a seller's representation.

When the title is real, the property is substantially more valuable and substantially safer than a concession in the same location, for exactly the reasons the comparison table shows: foreigner-friendly, perpetual, insurable, mortgageable.

Southern Zone Reality: Dominical, Uvita, Ojochal, Costa Ballena

Most of what buyers see for sale as 'ocean view' or even 'walking distance to the beach' in the Southern Zone is not in the ZMT at all. The coastline from Dominical south through Uvita, Ojochal, and Playa Tortuga rises steeply inland. The vast majority of listings sit on the ridges and slopes well above the 200-meter line, on standard titled land, and are straightforward fee-simple buys.

Walk-to-the-beach lots in neighborhoods like Las Olas, Playa Dominicalito, and the ridges just above Playa Hermosa and Playa Uvita are generally titled property. The beachfront inside the ZMT — the band from the tide line to 200 meters inland — is where concessions and the occasional possession claim show up, and these are the ones that require the ZMT-specific diligence covered above.

A few 2026 realities specific to this region buyers should know:

**Osa canton does not currently have a comprehensive approved cantonal plan regulador covering the whole ZMT coastline.** Priority sectors — notably Playa Uvita between Punta Achiote and the mangroves — have been the focus of planning work, but as of late 2026, an integrated plan for the full Dominical–Uvita–Ojochal stretch is not yet in force.

**The Comptroller General has an active review of Osa permit issuance.** In December 2025, the Contraloría General de la República formally accepted a complaint regarding how the Osa municipality has issued construction permits in the Fila Costeña — the coastal mountain range inland from the ZMT. No permit moratorium has been declared, but environmental groups have been requesting one, and audit findings may constrain future permit issuance. Buyers should expect more scrutiny of permits in this canton, not less.

**Walking inventory with a local agent matters more here than almost anywhere.** The difference between a titled ridge-top lot and a concession-held beachfront cabina, between a safe 2-year permit timeline and a 12-month SETENA quagmire, is not visible on the MLS listing. It is visible when someone who works these roads every week pulls the folio real and the plan regulador designation while standing at the gate.

A Pre-Offer Checklist for Any Property Within 500 Meters of the Shoreline

If you are considering any property that even looks like it might be inside or adjacent to the ZMT, these are the specific items to verify — in writing — before you write an offer. Not after. Not 'we'll check in due diligence.' Before.

1. **Distance from the mean high tide line.** Get a georeferenced survey (*plano catastrado*) showing the exact distance. Anything inside 200 meters is ZMT. Anything inside 50 meters is public zone — not for sale under any circumstance.

2. **Tenure type.** In writing from the seller's attorney: is this held as titled fee-simple property (with a *folio real*), as a registered municipal concession, or as a possession claim? Only one of those is the answer you want unless you are specifically buying a concession deal with a ZMT-specialist attorney.

3. **Current plan regulador costero designation** for that specific parcel. Zoned for tourism? Residential? Protected? What is the maximum footprint and height allowed?

4. **Concession status**, if applicable: current term, expiry date, renewal history, status of annual *canon* payments, any pending municipal disputes or audits touching that parcel.

5. **Foreigner eligibility structure.** If a concession is involved and the buyer is a foreigner without 5 years of residency, how will the holding entity be structured? Who holds the Costa Rican majority? What are the voting and transfer rights?

6. **Title study by an independent attorney** — not the seller's, not the one the seller recommends. For any 'titled' beachfront, the title study should specifically trace the registration back far enough to verify the Article 6 exception applies.

7. **Insurance and financing viability.** Can this asset be insured? Will a Costa Rican bank lend against it? If neither answer is yes, understand what that means for your exit.

The Papagayo Exception (Briefly)

If you ever look at property on the Golfo de Papagayo peninsula in Guanacaste, a different law applies — Ley 6758 (1982), which created the Polo Turístico Golfo de Papagayo under separate ICT administration. Papagayo concessions can run up to 50 years, foreigners can hold them without the 5-year residency rule, and the 50% Costa Rican ownership cap does not apply. That is Papagayo only. It has nothing to do with Southern Zone or Costa Ballena concessions, which are straight Ley 6043.

Working With a Team That Knows the Difference

The gap between a safe buy and a bad one in Costa Rica coastal real estate is often one question: title, concession, or claim? On the ground in the Southern Zone, the Cavu team's job is to tell you what a property actually is before you spend money on diligence to learn the same thing more expensively. Most of our inventory in Dominical, Uvita, and Ojochal is titled fee-simple land on the ridges above the ZMT — the safer and more liquid position for a foreign buyer.

The Bottom Line on the Costa Rica Maritime Zone

The ZMT is not a gotcha. It is a clearly defined 200-meter strip under a specific 1977 law, with well-understood rules for concessions, foreigner eligibility, and public access. Buyers who understand the regime before they look at coastal property make clean decisions. Buyers who do not tend to buy the wrong thing — usually possession rights sold as if they were title, sometimes concessions structured in a way that will not survive a renewal cycle.

The practical path for most US and Canadian buyers in the Southern Zone is simple: stick to titled fee-simple property above the 200-meter line, accept the premium that genuinely titled beachfront commands when it exists, and treat anything offered as 'possession' inside the ZMT as a hard no unless you are specifically structuring a concession deal with a specialist attorney.
