Buying in Tamarindo? Check the maritime zone before you fall for the beach.

What should you check first when buying property in Tamarindo?

In Tamarindo, start with the coastline. Most of the questions that matter for a buyer here come down to where a parcel sits relative to the legal maritime strip, what kind of right the seller actually holds, and whether protected land is involved. Price, views and rental potential can wait until those answers are on paper.

Tamarindo is in the canton of Santa Cruz, in Guanacaste province. The coast is heavily registered, which can make listings look more settled than they are. A parcel that appears on the official cadastre map is not automatically private property, and near the beach that distinction decides almost everything.

Our Tamarindo property check page is a starting point. Folio's free property check covers the official cadastre, maritime zone, protected areas and water layers for a parcel. Use the records described below to confirm what you see.

What do Folio's maritime zone numbers say about Tamarindo?

Folio measured the maritime strip along Tamarindo's coast as part of a town-level dataset covering 27 coastal towns. The full town figures are on our Tamarindo maritime zone data page. Here is what we found, measured in August 2026.

Two cautions about these numbers. First, parcel counts are lower bounds. We found parcels by sampling the Registro Nacional cadastre on a grid and removing duplicates, so some parcels can be missed but none are invented. Second, the map cannot tell a titled property from a state concession. Both appear as registered parcel geometry.

Why "registered" does not mean "titled" near the beach

The zona marítimo terrestre (maritime terrestrial zone, often shortened to ZMT) is defined in the maritime zone law published by the ICT as "la franja de doscientos metros de ancho a todo lo largo de los litorales Atlántico y Pacífico", a strip 200 metres wide along both coasts, measured from the ordinary high-tide line.

The law splits that strip in two. The first 50 metres are the Zona Pública (public zone). The remaining 150 metres are the Zona Restringida (restricted zone). In the restricted band, most registered parcels are state concessions: a right to use land for a period under conditions, not ownership.

So when you read that 92.4% of Tamarindo's strip is covered by registered parcels, read it as "almost all of it is spoken for", not "almost all of it is private". The seller may hold a title, a concession, or something messier. Only the registry record says which. For background on how concessions work, see our guide to the Costa Rica maritime zone explained for buyers.

One rule matters for foreign buyers. The law states that concessions are not granted "a extranjeros que no hayan residido en el país por lo menos durante cinco años", meaning foreigners who have not lived in Costa Rica for at least five years. If the lot is a concession, ask your attorney how this applies to you and to any company structure being proposed.

What does the protected land overlap mean for a buyer?

Roughly 69% of Tamarindo's maritime strip overlaps protected land, based on SINAC data covering national parks, refuges and Patrimonio Natural del Estado (state natural heritage, often called PNE). That is 1.555 km² of the 2.269 km² strip.

Restrictions on protected land are far stricter than the normal concession rules. A lot that looks like an ordinary beach-area parcel on a listing may sit partly or wholly on land where building, clearing or fencing is limited or not allowed. Even outside protected areas, the law prohibits fencing ("deslindar con cercas"), exploiting flora and fauna, and other development in the zone without legal authorization.

The law also treats all mangroves as public zone, "sea cual fuere su extensión", whatever their extent. If there are mangroves or wetlands near the lot, do not assume the public zone ends neatly at 50 metres from the sea. Ask your surveyor and attorney whether any mangrove or wetland boundary affects the lot.

Why do some parcels overlap the first 50 metres?

The first 50 metres are inalienable public zone. Yet Folio measured 0.5867 km² of registered parcel geometry overlapping that band in Tamarindo. That does not by itself mean anything improper is happening. There are three possible explanations, and they look identical on a map:

• Lawful concessions that legitimately reach into the area.
• Pre-1973 exceptions, which only an attorney reviewing the history can assess.
• Mapping offsets, where the drawn parcel and the official coastline do not line up precisely.

Only a registry pull, read by someone who knows what to look for, tells these apart. If a lot you like touches the first 50 metres, treat it as a question to resolve, not a conclusion.

Which records should you pull for a Tamarindo lot?

These are the documents that turn map impressions into facts. Your attorney or notary will know how to request and read them, many through the Registro Nacional digital services.

1. The certificación literal (full registry certificate) of the property, showing the registered owner or holder, the nature of the right, and any gravámenes (encumbrances) and anotaciones (pending annotations).
2. The plano catastrado (registered cadastral survey map), to compare the parcel's drawn boundaries with what you were shown on site.
3. Confirmation of whether the parcel is titled land or a concession, and if a concession, its term, conditions and current standing.
4. An overlay of the parcel against the 200 m maritime line, the 50 m public zone and any protected area or mangrove boundary.
5. Municipal records from Santa Cruz, including property tax status and, for concessions, the concession file and payment history.
6. Whether a coastal regulatory plan applies to that stretch of coast. The ICT maritime zone programme publishes information on coastal plans and regulations.

What questions should you ask about a specific Tamarindo property?

Bring these to the seller, the agent and, above all, your attorney:

• Is this property titled, a concession, or partly each? Which documents prove it?
• How far is the nearest boundary from the ordinary high-tide line, and who measured it?
• Does any part of the parcel overlap protected land, mangroves or an estuary?
• If it is a concession, can I hold it given my residency status, and what conditions apply to transfer?
• Do the cadastral map and the boundaries on the ground match?
• Are there liens, annotations or unpaid taxes or concession fees?
• Were existing buildings authorized, and do they fall within any restricted band?

What can the public data not tell you?

Folio's numbers describe the coastline as a whole. They show how crowded and how protected Tamarindo's strip is, and they flag which questions deserve attention. They do not tell you whether a particular lot is a title or a concession, whether a concession is in good standing, or how a pre-1973 history will be treated.

Those answers sit in the registry and municipal files, and their meaning is a legal judgement. Folio shows what the public records say. An attorney or notary advises on what that means for your purchase.
