The State of Costa Rica's Maritime Zone

We mapped every registered parcel touching the legal 200-meter Maritime Zone in Costa Rica's top beach towns — official government data nobody had ever put together. The result is the clearest picture yet of who holds the country's most wanted 200 meters, and the one thing the map can't tell you.

What the law says about the first 200 meters

Since 1977, Ley 6043 divides every Costa Rican beach into three worlds. Standing on the sand and walking inland, this is what you cross:

the sea

High-tide line Start here

The pleamar ordinaria — where the 200 meters begin counting.

0 – 50 m

Public zone Can never be owned

Inalienable. No titles, no concessions, no fences. Yet our study measured registered parcel geometry overlapping this strip in every town — concessions, pre-1973 titled exceptions, and mapping offsets a buyer can't distinguish on the map.

50 – 200 m

Restricted zone Concessions only

The state leases this land as municipal concessions — renewable, conditional, and registered in the National Registry just like a title. Foreigners face ownership limits here that don't exist one meter further inland.

200 m +

Titled land possible Where fee-simple begins

Full private ownership exists only beyond the 200-meter line — unless a rare pre-1973 exception applies inside it.

The core finding

The registry map looks identical for titled land and concession land

In Santa Teresa, 96.6% of the legal Maritime Zone is covered by registered parcels. Registration is not ownership: most of those fincas are state concessions. Nothing in the parcel lines tells you which kind you're looking at — and that difference decides what you can own, renew, build, or lose.

Share of each town's 200m strip covered by registered parcels · number = parcels touching the strip. Higher isn't safer — it means more of the beach is spoken for, in one legal form or another.

Town by town

Twenty-seven beaches, twenty-seven different stories

Can a foreigner own the beach?

The rules for foreigners, in plain language

Article 47 of Ley 6043 is blunt. A concession in the restricted zone cannot be held by: a foreigner with fewer than five years of residency in Costa Rica; a company domiciled abroad; a company with bearer shares; or a company whose capital is more than 50% foreign-owned (Reglamento 7841-P, art. 25). Some municipalities apply it even more strictly.

What about the "local partner" structures you hear about? They exist all over the coast: a Costa Rican partner holds 51% on paper while foreign money funds the project. Understand the risk before copying them: authorities look at substance over form, and a structure built to dodge art. 47 can make the concession null. This is exactly the kind of thing to put in front of your own lawyer, not to improvise.

Inheritance and mortgages: a registered concession is a real right that can generally be mortgaged and inherited, but transfers need municipal approval and heirs must themselves satisfy the foreigner rules. A transfer that breaches the thresholds is void.

Seven myths that cost buyers money

What people get wrong about the Maritime Zone

"Beachfront is always titled"

Most beachfront inside the 200m is concession or untitled public domain. True titles inside the zone are exceptions: pre-1973 registrations and specific urban areas (parts of Jacó, Puntarenas, Limón).

"The seller owns the concession"

Only the person or company named in the Registro de Concesiones holds it. Possession, fences, even buildings prove nothing. Verify the registration, not the story.

"A concession = ownership"

A concession is a time-limited right to use public land (commonly 5-20 years). It can expire, be cancelled, and carries conditions a title never has.

"It will become titled eventually"

The restricted zone is state property by law. No concession "matures" into a title. Betting on future titling is betting against Ley 6043 itself.

"I can build whatever I want"

Construction requires an approved plan regulador, municipal permits, and often SETENA environmental approval. No plan regulador usually means no meaningful building rights.

"The beach in front is mine"

The first 50 meters are inalienable public domain (art. 10). No fences, no "private beach", no exceptions for anyone, ever.

"Transfers are automatic"

Every assignment, mortgage, or change of use of a concession needs prior municipal authorization (Reglamento 7841-P). An unauthorized transfer can void the right entirely.

Who governs the coast

Seven institutions touch every coastal deal

Municipality

Grants and cancels concessions, collects the canon, approves transfers, issues building permits. The single most important office for concession land.

ICT

Tourism authority: reviews coastal planning, declares tourist zones, issues binding legal opinions on concession rules.

INVU

Urban-planning institute: co-approves the plan regulador that determines whether anything can be built at all.

Registro Nacional

Keeps titles AND the separate Registro de Concesiones. Where every claim gets verified, and where Folio reports pull from.

SETENA

Environmental review (under MINAE). Coastal construction typically needs its viability approval before permits.

SINAC / MINAE

Protected areas, mangroves, refuges. Where a park or Patrimonio Natural overlaps the zone: usually no concessions, no building.

Migración / Hacienda

Certify the residency years behind art. 47 eligibility; tax obligations run alongside the canon.

Before you sign anything

The 8-step coastal due-diligence path

  1. Locate the exact parcel on the cadastre map and get its finca or concession number. (Folio's free check does this from a map tap.)
  2. Determine its zone: fully outside the 200m, in the restricted 50-200m band, or touching the public 50m.
  3. Pull the registry record: standard property registry for titles, Registro de Concesiones for concessions. Confirm the seller is the registered holder.
  4. If titled inside the 200m: demand the title's origin (pre-1973? urban exception law?) and have counsel confirm its validity chain.
  5. If concession: read the concession contract itself: term, use, canon status, conditions; confirm your own art. 47 eligibility.
  6. Check the plan regulador with the municipality: does one exist, what zoning applies, what can actually be built.
  7. Overlay the environment: protected areas, mangroves/wetlands, river setbacks, flood exposure. (Folio's layers show these.)
  8. Verify municipal standing: canon payments current, no cancellation proceedings, taxes paid, no municipal liens.
Questions buyers actually ask

Maritime Zone FAQ

Can I get a mortgage on concession land?

Sometimes. Concessions are real rights that can be encumbered, but the mortgage needs municipal authorization and lenders are far more conservative than with titled land. Many banks simply decline; private financing is common.

Can my children inherit a concession?

Yes in principle, but the heirs must themselves satisfy the foreigner-eligibility rules and the municipality must approve the change of holder. An heir who fails art. 47 cannot simply step in.

Can I hold a concession through a Costa Rican corporation?

Only if the corporation's capital is at most 50% foreign-owned, with no bearer shares and Costa Rican domicile. Nominee structures that fake the 51% are the classic trap: they risk nullity.

Can I run an Airbnb or hotel on a concession?

Only if the concession's approved use and the plan regulador's zoning allow lodging, plus normal business permits. Using residential concession land for tourism can be a cancellation ground.

What happens when the concession term ends?

You apply for renewal. Renewal is normal when conditions were met, but it is not automatic or guaranteed. On expiry or cancellation, improvements can revert to the state without compensation.

How much is the annual canon?

It varies by municipality, zoning and appraised value; there is no single national rate. Ask the municipality for the current appraisal and rate for the specific parcel before buying. Unpaid canon is a cancellation ground.

Is any beach in Costa Rica private?

No. The first 50 meters are inalienable public domain everywhere. What varies is what stands behind those 50 meters.

How do I know if a beachfront title is real?

Its origin must trace to a recognized exception: a pre-1973 registration or a specific urban/titling law. The registry entry plus its history tells the story; Folio's verified report pulls the record, and a notary confirms the chain.

Methodology

Built only on official data

How we measured the Maritime Zone

The legal strip is a 200-meter landward buffer of the official IGN 1:5000 coastline (SNIT), computed in Costa Rica's official CRTM05 projection and clipped to official district boundaries. The 50-meter public zone uses the same method.

How we found the parcels

We sampled each strip on a 45-meter grid against the National Registry's public cadastre service — 28,434 lookups, zero errors — deduplicated by finca number, then intersected each parcel's exact registered geometry with the strip. Counts are lower bounds: parcels narrower than 45m can be missed.

What the 50m overlap does and doesn't mean

Registered geometry overlapping the first 50 meters is a measurement, not an accusation. It includes lawful concession registrations, rare pre-1973 titled exceptions, and offsets between the cadastral mosaic and the coastline. Its lesson is precisely the report's thesis: the map alone cannot tell you a parcel's legal nature.
