A clean title in Costa Rica doesn’t always mean a clean buildable footprint. Article 33 of the Forest Law (Ley Forestal No. 7575) is the reason why — and it’s one of the most commonly missed risks in coastal and rural property underwriting.
Article 33 declares a set of automatic “protection areas” (áreas de protección) around water features, regardless of what’s written on a property’s title or registered survey:
- A 100-meter radius around permanent natural springs
- A buffer along rivers, streams, and creeks — 15 meters on each side in rural zones and 10 meters in urban zones on flat terrain, widening to 50 meters on each side if the terrain is steep
- Recharge areas and aquifers tied to those springs
Article 34 then prohibits construction and tree removal inside those zones outright, with only narrow exceptions for projects specifically declared a matter of national convenience by the Executive Branch.
Why this matters for underwriting
These protection zones exist by operation of law, not by registration. A property’s título de propiedad and registered plano catastrado show the legal boundaries of the parcel — they don’t subtract out the protection buffers along any creek, spring, or steep slope that happens to cross it. Two properties that look identical on paper, same square meterage and zoning, can have very different actual buildable area once the water features and slope are mapped.
This is a particularly live issue in coastal and mountain markets, where small streams, seasonal creeks, and steep terrain are common and easy to miss on a quick site visit — especially in dry season, when a creek bed can look empty.
What this means in practice for a buyer
- A topographic and hydrological survey — not just a registry search — is needed to confirm what protection areas, if any, cross the parcel
- “Buildable area” on a listing sheet should never be taken at face value; it needs to be checked against Article 33 zones
- Steep terrain triggers the wider 50-meter buffer, which can quietly remove a meaningful share of usable land on a sloped lot
- INVU (Instituto Nacional de Vivienda y Urbanismo) issues the formal alineamiento — the official determination of where these buffers fall on a specific property — and getting that documentation before close is the only way to know for certain
None of this means a property with a creek or spring on it isn’t a viable deal. It means the buildable footprint needs to be underwritten on its own, separate from the registered lot size, before a development plan or appraisal gets built around an assumption that turns out to be wrong.
This is general market commentary, not legal advice. Any specific parcel needs a Costa Rican attorney and a proper alineamiento before you rely on it.
