Costa Rica's Maritime Zone Rule: What Americans Need to Know Before Buying Beachfront

Costa Rica passed the Maritime Terrestrial Zone Law — Ley sobre la Zona Marítimo-Terrestre, or Law 6043 — in 1977. The purpose was straightforward: prevent private ownership of the coastline so that beaches remain a national asset, open to the public, and protected from unchecked development. The law applies to virtually all of Costa Rica's 1,290 kilometers of Pacific and Caribbean coastline, with a handful of historical exceptions (the city of Puntarenas, the Gulf of Papagayo project zone, and certain islands). Everywhere else, the first 200 meters measured horizontally from the average high-tide line belongs to the state. You can read the law on the official Costa Rica government SINALEVI legal database or a cleaner English summary from Blue Zone Legal's ZMT guide.

The 200 meters are split into two zones. The first 50 meters from the high-tide line is the Zona Pública — the Public Zone. Under Law 6043 nobody, foreign or Costa Rican, can own, lease, or build in the public zone. It is open for public use, permanently. The only exceptions are small-scale installations like lifeguard stations, sanitary facilities, or structures authorized by the Costa Rican Tourism Institute (ICT). If you are looking at a house that sits inside the first 50 meters, it is either illegally built (a common problem in older beach towns) or the measurement is wrong.

The next 150 meters is the Zona Restringida — the Restricted Zone. This is where concessions exist. The state retains ownership, but the municipality, with ICT oversight, can grant a concession (concesión) to occupy and use the land for 5 to 20 years, with the option to renew. The concession is not ownership. It is a long-term lease, with annual fees (typically 2.5% of the assessed value per year, per Coldwell Banker Pacific Realty's ZMT explainer), and it can be terminated or non-renewed if the holder breaches the conditions or if the municipality changes the regulatory plan.

One more piece matters: before any concession can be granted at all, the municipality must have an approved Plan Regulador (regulatory zoning plan) for that stretch of coast. Without an approved plan, ICT cannot authorize new concessions and cannot issue building permits inside the ZMT. As of 2025, large stretches of the Nicoya Peninsula, the Osa Peninsula, and parts of the Caribbean still do not have approved Planes Reguladores, which means properties in those areas are in regulatory limbo: owners hold expired or provisional concessions, can't get permits, and can't legally sell except as informal possession rights. Tico Times has covered this problem extensively.

Costa Rica does have titled beachfront — just not much of it. Titled property (propiedad titulada) exists outside the ZMT entirely or falls under one of the historical exemptions (Puntarenas city, Papagayo, Jacó's older downtown, and parts of Limón). These properties sit in the regular national land registry, the Registro Nacional de la Propiedad, and work like property everywhere else: fee simple, mortgageable, inheritable, freely transferable, no nationality restriction. A foreigner can own titled beachfront the same way they own a condo in San José. The confusion starts because a real estate agent will describe a property as 'beachfront' or 'oceanfront' without specifying whether it's titled or concession. On the Nicoya Peninsula especially, you'll tour a house that appears to be sitting 80 meters from the water, and the agent will describe it as 'your piece of the Pacific' — and what you're being sold is a 20-year lease from the municipality, not ownership.

The legal test for which one you're looking at is simple: pull the folio real from the National Registry. If the folio real shows a registered plano catastrado (cadastral plan) and a natural person or corporation as the owner, it's titled. If there's no folio real and the property exists only as a concession recorded at the municipality and at ICT, it's ZMT. Your lawyer can run this check in a few hours for any property you're serious about. Never sign anything, never wire a deposit, and never trust a seller's word on which category applies. The relevant national databases are the Registro Nacional de la Propiedad and, for concessions, the ICT regulatory office. Blue Zone Legal, Tropisphere Real Estate, and Ballena Properties all publish primers that are blunter than what you'll get from a commission-paid agent.

The other thing to watch is the line between titled and concession on the same lot. Some beachfront properties are split: the front portion is concession land inside the ZMT, the back portion is titled. You might be buying a 2,000 square meter parcel where the house sits on the 800 square meters of titled land and the ocean-facing pool and garden sit on 1,200 square meters of concession. The price the seller quotes is for the whole thing. Your actual ownership rights are on only 40% of it. LX Costa Rica and Costa Rica Green Estate both walk through split-parcel scenarios with examples.

Here is the rule that catches most Americans: to hold a concession in the Restricted Zone, you must either be a legal resident of Costa Rica for at least five years, or you must hold the concession through a Costa Rican corporation (sociedad anónima or SRL) in which at least 51% of the shares are owned by a Costa Rican citizen or a foreigner with five-plus years of legal residency. Foreigners who have been in the country less than five years can hold up to 49%, and no more.

That means if you fly in tomorrow on a 90-day tourist visa with a cashier's check, you can't personally obtain a ZMT concession. And you can't put the concession entirely into a company you wholly own. You need a Costa Rican partner who legally holds majority control. This is the rule, and it is not negotiable at the municipal level — the municipality will reject the concession application, and if you try to work around it by using a 51/49 corporate structure with a figurehead partner, you're exposed to the risk that a future administrator or court finds the structure to be a sham and cancels the concession entirely.

The workarounds that are sold to foreign buyers fall into three categories. The first is the 'trusted partner' structure, where your Costa Rican lawyer or a local acquaintance holds 51% of the corporation and signs a private agreement acknowledging that the economic interest is really yours. This is common, it is broadly tolerated, but it is not airtight. If your partner dies, divorces, or sues you, their 51% is legally theirs. Ballena Properties' 2025 pitfalls article and Bluewater Properties' foreign buyer guide both document cases where this unraveled. The second category is the 'bought residency' workaround: you obtain Costa Rican permanent residency via the Inversionista (Investor) program, live in the country for five years, and then personally apply for the concession. Costa Rica's investor residency threshold is $150,000 as of 2026, per Costa Rica's Dirección General de Migración y Extranjería. The five-year clock starts at legal residency, not arrival. The third category is the dual-concession 'shared lawyer partner' trap: some lawyers use the same Costa Rican 'partner' for multiple foreign clients, which violates the rule that any one person can only hold one concession. When discovered, the concession is cancelled. Remax Ocean Surf & Sun and LivingCostaRica both warn about this.

The reason the rule exists is straightforward: Costa Rica doesn't want the entire coastline in foreign hands. It's a policy call the country made in 1977 and has reinforced through updates to Law 6043. You can disagree with it, but you can't paperwork your way around it in a way that a future Costa Rican court will respect.

A ZMT concession in Costa Rica runs for a term set by the municipality, anywhere from 5 to 20 years, with 20 being the maximum under Law 6043. Twenty-year concessions are standard for residential use in well-established tourism areas like Tamarindo, Santa Teresa, Nosara, Manuel Antonio, and Puerto Viejo. At the end of the term, the concession must be renewed — it does not auto-renew. The municipality reviews the application, confirms the current Plan Regulador still permits the use, confirms annual fees are up to date, and then decides whether to grant a new term.

In practice, renewals are usually granted. Concession holders who have paid their annual canon (fee), maintained the property in compliance with the zoning plan, and haven't violated any environmental rules can expect to be renewed. But 'usually' is not 'always.' The municipality has legal authority to deny renewal if the regulatory plan changes — for example, if a new Plan Regulador rezones the area from residential to commercial, or if SETENA (the national environmental agency) identifies the site as ecologically sensitive. The Tico Times' ZMT feature documents cases where renewals were denied and the concession holder had to demolish structures at their own expense.

Annual fees on a concession are not the same as property taxes. Titled property in Costa Rica pays a property tax of 0.25% of the registered value per year — one of the lowest rates in the Americas, per the Ministerio de Hacienda's tax code. Concession property pays an annual canon of 2.5% of the assessed value, ten times the property tax rate. On a property assessed at $300,000 that's $7,500 per year, every year, paid to the municipality for the right to continue occupying the land. The assessed value can be updated by the municipality periodically, sometimes upward. 2Costa Rica Real Estate and Exclusive Homes Costa Rica both walk through the math.

Put those two numbers together and a 20-year concession on a $300,000 property costs $150,000 in annual fees alone, plus whatever you paid up front to 'buy' the concession from the previous holder, plus maintenance, plus Costa Rican income tax if you rent it, plus the cost of eventually renewing. The total cost of occupancy over a 20-year term can exceed the nominal 'purchase' price, and at the end you don't own anything — you have a renewal application pending at the municipality.

For comparison, our writeup on cost of living in Costa Rica breaks down what rent actually costs in the same beach towns. For a lot of Americans the honest math is that renting a house in Santa Teresa or Nosara for $1,800-$3,000 a month is cheaper than 'owning' a concession property, once you include annual canon, renewals, and legal fees.

The story plays out the same way in every beach town in Costa Rica, and it's worth walking through because knowing the pattern is most of the protection. You vacation in Tamarindo or Nosara. You fall in love. You meet a real estate agent at a sunset bar. The agent shows you a house walking distance from the beach, sells you on the 'oceanfront lifestyle,' quotes a price of $450,000, and introduces you to 'their lawyer' who will handle everything. The lawyer confirms the property is 'in the name of a Costa Rican corporation,' tells you that 'foreigners buy this way all the time,' and draws up a share purchase agreement where you acquire 49% of the corporation for $450,000 and a Costa Rican nominee holds the other 51% for symbolic consideration. You sign, you wire the money, you get the keys, you post a photo to Instagram.

What you actually bought: 49% of the shares of a Costa Rican corporation whose sole asset is a 20-year concession from the Santa Cruz municipality, with 12 years remaining on the term, assessed at $180,000 (the corporation's registered value, not what you paid), carrying an annual canon of $4,500. The 51% belongs legally to the nominee. If you and the nominee have a falling out, they can theoretically vote the corporation to sell the concession and distribute proceeds however the shareholder agreement allows — and in most of these setups the shareholder agreement was drafted by the lawyer who introduced the nominee, who may or may not still represent you. If the nominee dies intestate, their 51% passes to their heirs, who may have no idea about the private side deal.

This isn't hypothetical. Pitfalls of Buying Property in Costa Rica for Foreigners and Papagayo Real Estate's FAQ walk through real-world versions. The r/IWantOut Costa Rica thread has American expats explicitly warning against buying beachfront concessions on the way in. The r/expats Costa Rica buying property thread has a long comment from someone who spent two years unwinding exactly this structure. r/ExpatFIRE discussions on Costa Rica property generally steer people toward titled inland property and rentals on the coast. On r/CostaRica, 'Can an American really own beachfront?' has locals spelling out the rules in plain English. And r/AmerExit's Costa Rica residency thread covers the Inversionista pathway if you're serious enough about living on the coast to commit five years.

The protection is the opposite of the usual script. Hire your own lawyer, not the agent's lawyer, before you even look at properties. Pay for an independent review of the corporation's books, the concession file at the municipality, the Plan Regulador status for that beach, and the nominee's track record. Verify that the nominee is not on other concessions. Get an environmental due diligence from SETENA. And honestly consider whether you want a 20-year lease on land you'll never own, or whether a titled property 500 meters inland — fee simple, 0.25% property tax, no nominee, no renewal risk — is the smarter play. We cover the broader due-diligence framework in our post on common scams in Costa Rica for Americans and walk through the Inversionista visa pathway in Costa Rica's cheapest residency-plus-property routes.

This isn't a blanket 'never buy a concession' post. There are situations where a concession is the right call. If you're planning to obtain Costa Rican residency anyway and will clear the five-year mark, you can eventually transfer the concession into your own name and run it as if you owned it. If you run a small hotel, surf camp, or rental business where being inside the ZMT is the whole point of the business model, a concession is the only way to operate legally. If you have a deep, long-standing relationship with a Costa Rican family who are genuinely your partners in a real commercial project, a 51/49 corporate structure can work the way Law 6043 actually intends it to work.

What makes those scenarios work and the 'American with a cashier's check' scenario fail is the same thing: alignment between the legal structure and your actual life. If you actually live in Costa Rica, actually speak Spanish, actually know your partner, and actually plan to run the property as a business that respects the Plan Regulador and the canon schedule, a concession is just a long lease and long leases work all over the world. What doesn't work is treating a concession like it's a Florida deed.

There are also hybrid plays worth considering. Buy titled property near the beach, not on it. A 500-square-meter titled lot 300 meters inland in Nosara will sell for a fraction of a 1,000-square-meter concession on the sand, you own it free and clear, and the beach is still a five-minute walk. You get the Costa Rica lifestyle without the 2.5% annual canon and the 49/51 problem. TheLatinvestor's 2026 Costa Rica guide argues for exactly this approach.

Another option: buy titled property in one of the exempt zones. Jacó's older downtown, parts of Puntarenas, the Papagayo project zone, and some of the Caribbean south of Limón have titled beachfront available. Prices are higher per square meter than concession land because you're actually getting ownership, but you're not paying canon, you're not renewing, and you can mortgage it. Papagayo is the most luxury-oriented, Jacó the most accessible, and the Caribbean coast the most affordable. See Papagayo Real Estate's FAQ for the exemption details and International Living Costa Rica's coverage for comparative pricing.

If you've read this far and still want to pursue a concession, here is the minimum due diligence every serious Costa Rican real estate lawyer will run — and the minimum you should demand in writing before any money changes hands.

1. Pull the concession file from the municipality. You want the original concession decree, the current term, the assessment value, the canon payment history for the last three years, and any outstanding notices. If the current holder is behind on canon, the municipality can sell the concession at auction to recover — you do not want to be the third buyer in line behind the auction.

2. Verify the Plan Regulador is approved and current. Ask the municipality for the zoning for the specific parcel. If the Plan Regulador is still in draft or under environmental review (several Guanacaste municipalities are in this state), no new concessions can be granted and existing ones may be in limbo. ICT's concession oversight page publishes the status for each municipality.

3. Environmental due diligence via SETENA. The Secretaría Técnica Nacional Ambiental is the national environmental permitting agency. Confirm the parcel has a D1/D2 environmental viability ruling or is exempt. If the site has sea turtle nesting, mangrove, or protected forest overlays, building rights are restricted. SETENA's public files are searchable.

4. Verify the 51% holder. If you're buying into an existing corporation, run a background check on the Costa Rican partner. Confirm they hold no other concessions (Costa Rica's one-concession-per-person rule is strict). Ask for notarized confirmation that they understand the deal and any side agreements. Get the shareholder agreement translated to English and reviewed by an independent lawyer — not the one the seller provided.

5. Run the corporation's financials. Corporations in Costa Rica are required to file annual returns and pay the educational and cultural stamp tax, the timbre, and the legal entity tax. Confirm all of these are current. A corporation with lapsed filings is a corporation the state can dissolve, taking the concession with it.

6. Understand the exit. How will you sell in 5, 10, or 15 years? The buyer pool is smaller for concessions than for titled property, banks don't lend against them, and transactions are cash. If you need liquidity, concession land is the wrong holding vehicle.

7. Budget for total cost of occupancy. Price + closing costs + annual canon over your expected holding period + renewal costs + legal and tax compliance + maintenance. Compare that to the equivalent rental. On a 10-year horizon the rent option often wins.

8. Budget for US tax compliance. Owning foreign real estate triggers nothing on its own for US persons — real property isn't a reportable foreign financial asset — but owning shares in a foreign corporation that holds the property does. That's Form 5471 territory, with serious penalties for nonfiling. See IRS Form 5471 instructions and talk to a US tax professional who handles CFCs before you sign. Our own avoid double taxation on foreign property post covers the basics.

The US Embassy in San José publishes a property acquisition warning page that flatly recommends using independent attorneys and avoiding seller-referred ones. That's not legal advice — it's the State Department being tired of bailing out Americans who didn't do the diligence. Take the hint.

After all that, plenty of Americans decide that Costa Rica beachfront concession property isn't for them, and they're right. The structural rules of Law 6043 are not going to change. The 51% Costa Rican ownership requirement is not going to change. The 2.5% annual canon is not going to change. These are policy choices Costa Rica has made and re-affirmed for almost 50 years. If any of those facts breaks the deal for you, walk. Rent in the same beach town for a fraction of the annual cost, or buy titled property inland and visit the beach like everyone else.

The people who buy concession property successfully in Costa Rica share three traits. They have real residency in the country — five years or clearly on the pathway. They have a genuine Costa Rican partner, not a hired nominee. And they're using the concession for a real commercial purpose that justifies the legal complexity — a hotel, a surf lodge, a rental operation — where being in the ZMT is the whole point of the business. If you're the American with a cashier's check looking for a retirement villa on the beach, you are the person the 49/51 rule is designed to slow down, and the structure is not going to bend for you.

The good news: Costa Rica has a huge amount of titled property available to foreigners on identical terms to Costa Rican nationals. The Central Valley, the Southern Zone, Guanacaste's inland hills, the Lake Arenal area, and the Caribbean south of Limón all offer titled fee-simple property at competitive prices, with real mortgages available from Costa Rican banks to qualified buyers. You can live in Costa Rica without the ZMT headache. Our post on the buying process for Mexico walks through an even more foreigner-friendly beachfront mechanism — the fideicomiso — for comparison, and our Costa Rica vs Panama vs Mexico analysis in the cheapest residency-plus-property roundup is worth reading if you're still deciding which Latin American coast to buy on.

The one-line summary you can give a friend: in Costa Rica, foreigners can own the beach town, they just can't own the actual beach. Plan the purchase around that fact and the country is an excellent place to live. Ignore it, sign the agent's share purchase agreement without reading it, and you're one of the Americans whose stories show up on Reddit two years later, wondering why the nominee is now in control of the corporation you thought you owned.
