Buying in Puerto Viejo? Check the maritime zone before you check the view.

Why does the maritime zone come first in Puerto Viejo?

Puerto Viejo sits on the Caribbean coast in Limón province, inside the canton of Talamanca. Much of the town faces its shoreline, and that is where the maritime zone questions start. If a lot is near the beach, the first thing to settle is what kind of land it is: private titled property, a concession granted by the municipality, or state land with no registered rights at all.

Costa Rica's maritime law, Ley 6043 on the Zona Marítimo Terrestre, defines the zone as "la franja de doscientos metros de ancho a todo lo largo de los litorales Atlántico y Pacífico" (Article 9: a strip 200 metres wide along both coasts, measured from the ordinary high-tide line). The law names the Atlantic (Caribbean) coast alongside the Pacific. If you want the full background before reading the town numbers, our guide to the Costa Rica maritime zone (ZMT) walks through it.

The law splits that strip in two. The first 50 metres are the Zona Pública (public zone), and Article 10 describes the remaining 150 metres as the Zona Restringida (restricted zone). Article 11 adds that all mangroves are public zone "sea cual fuere su extensión", whatever their size. That matters wherever a lot is near mangroves.

What do Folio's Puerto Viejo numbers actually say?

Folio measured the maritime strip town by town for its 2026 study of the coastline. For Puerto Viejo, the measurement was taken on 2026-08-02. The method overlays a 200 metre landward buffer of the official national coastline on parcel geometry from the Registro Nacional cadastre. All parcel counts are lower bounds: the real number can only be equal or higher.

The full breakdown, with notes on each field, is on the Puerto Viejo maritime zone data page. A word of caution: "registered" in this dataset covers both titles and concessions. The map cannot tell them apart. Only a registry pull can.

What does 54.2% coverage mean for a buyer?

Only 54.2% of Puerto Viejo's maritime strip is covered by registered parcels. The rest, close to half the strip, has no registered parcel geometry on it. It is tempting to read that as open land. It is not.

Unregistered land in the maritime zone is public domain. It does not become buyable because nobody has registered it. If someone offers you a beach plot that has no folio real (registry entry) and no concession on record, what they are offering is possession, and possession of state land is not a registered right you can rely on. Ask your attorney how the law treats that situation before money changes hands.

Even inside the registered half, registration does not mean ownership. In the 50 to 200 metre band, most registered parcels are state concessions, not freehold titles. A concession is a time-limited right granted by the municipality, with conditions attached. Our guide to buying a beachfront lot in Costa Rica explains how that differs from owning land outright.

Why does registered land inside the first 50 metres matter?

The public zone is meant to stay public. Yet Folio measured 0.2887 km² of registered parcel geometry overlapping Puerto Viejo's first 50 metres. That figure has three possible explanations, and the map alone cannot sort them:

• Lawful concessions, which only the registry record can confirm.
• Pre-1973 exceptions, which only the registry history can confirm.
• Mapping offsets, where a drawn boundary sits a little off its true position, so a lot that is really behind the line appears to cross it.

If the lot you are considering is among these, ask your attorney whether you need the registry history and a fresh survey against the official high-tide line. Article 12 of the law prohibits fencing, building or cutting trees in the zone without legal authorisation, so ask your attorney how the answer affects what you plan to build.

The protected land overlap here is small: 0.003 km² of the strip, per SINAC data. Small is not zero. If a lot sits near a refuge or forest boundary, ask your attorney to check the environmental status directly.

Which records should you pull for a Puerto Viejo lot?

Work through these in order. Each one answers a question the previous one raises.

1. The registry certification. From the Registro Nacional digital services, a certificación (official registry extract) shows the registered owner and any gravámenes (encumbrances) and anotaciones (pending annotations). This tells you whether the seller is actually the owner on record.
2. The plano catastrado. The cadastral survey plan shows the lot's boundaries and area. Compare its shape and size with what you were shown on the ground.
3. Maritime zone status. Find out whether the lot falls inside the 200 metre strip and, if so, whether it is a title or a concession. The ICT's maritime zone programme covers coastal plans and regulations; ask the Municipality of Talamanca about concession records for the lot.
4. Municipal records. Ask for property tax status and, for any concession, the concession file and its payment history.
5. Water. Confirm where the water comes from and whether that right is documented. A lot without lawful water access is a different purchase.

A Folio verified report covers several of these in one search: registered owner, liens, taxes, water rights and the exact maritime line, checked by a person and delivered within 24 hours for $29. It shows what the records say. Your attorney or notary is the one who advises on what to do about it.

What questions should you ask about a Puerto Viejo property?

• Is this a titled property or a concession? Ask to see the document that proves which.
• If it is a concession, are you eligible to hold it? Article 47(a) says concessions are not granted to foreigners who have not resided in the country "por lo menos durante cinco años" (at least five years). Ask your attorney how that applies to your residency and any company structure.
• Does the lot touch the first 50 metres or any mangrove? If yes, what explains it: a concession, an old exception or a mapping offset?
• Does the plano match the boundaries on the ground, including fences and existing buildings?
• Were existing structures in the zone built with authorisation?
• Are there liens, mortgages or annotations on the registry entry, and will they be cleared before closing?
• Are property taxes and any concession fees current?

What can a free map tell you, and what can't it?

Folio's free map lets you tap a lot and see its finca number, area, perimeter and boundary from the official cadastre, plus a flag if it falls in the maritime zone. That is a useful first screen for location and shape. You can also start from the Puerto Viejo property check page.

Everything about title sits outside that first screen. The registered owner, recorded charges and the survey plan come from the registry, through your own pull, your attorney, or the verified report. Do not treat a clean-looking boundary on a map as a clean title.
