Costa Rica Concession Properties: The ZMT Risk Explained

Why Most “Beachfront” Property in Costa Rica Is Not What It Seems

Costa Rica is marketed extensively as a freehold property destination — and much of its interior and highland property genuinely is freehold (titled, registered, transferable). The problem arises at the coast. The most desirable, highest-priced, most heavily marketed coastal properties — beachfront villas in Guanacaste, beach communities on the Nicoya Peninsula (Sámara, Santa Teresa, Mal País), Pacific coast towns (Manuel Antonio, Dominical, Uvita), and Caribbean beach towns (Puerto Viejo, Cahuita) — sit on or near the ZMT.

The Zona Marítimo Terrestre is not a small, easily-avoided strip. It extends inland 200 metres from the ordinary high-tide line along Costa Rica's entire 1,228km of coastline. In popular beach towns with dense development, a significant portion — sometimes the majority — of the residential property closest to the water sits within this zone. And within this zone, freehold title legally cannot exist.

The legal foundation is Ley No. 6043 (Ley sobre la Zona Marítimo Terrestre), enacted in 1977. Article 1 declares that the ZMT “is part of the national domain and cannot be acquired by ownership or prescription.” Article 9 defines the restricted zone as the 150m inland of the 50m public zone, where concessions may be granted by municipalities for specific uses. These provisions have been consistent since 1977 and have survived numerous constitutional challenges.

The practical consequence: when a real estate listing in Guanacaste or Manuel Antonio says “direct beachfront” or “steps from the beach,” there is a meaningful probability that the property — or part of it — is in the ZMT concession zone. A competent Costa Rican abogado will determine this in their title research. An uninformed buyer who trusts the listing description without independent verification may purchase a concession believing they are purchasing freehold.

The ZMT Structure in Detail: Zona Pública and Zona Restringida

Zona Pública: The First 50 Metres

The first 50 metres measured inland from the ordinary high-tide line is the zona pública. This is absolute public domain under Ley 6043 Article 9. The implications are categorical:

• No private use, construction, or occupation is permitted, for any purpose.
• No concession can be granted within the zona pública — it cannot be leased, licensed, or privately used.
• Any structure built within the zona pública is illegal and subject to demolition without compensation.
• The high-tide line, not a fixed surveyed line, defines the boundary — which can shift with erosion, sea-level change, and storm events.

A significant number of structures in Costa Rican beach towns violate the zona pública prohibition. They were built during periods of less stringent enforcement or with improperly issued permits. Enforcement has increased significantly since 2010. A Canadian buyer who purchases a property that encroaches into the zona pública may find themselves holding a structure that regulators can order demolished — with no compensation and no recourse against the prior seller if the encroachment was disclosed in the title research they chose not to have.

Zona Restringida: The 50m–200m Band

The 150-metre band between the 50m and 200m marks from the high-tide line is the zona restringida. Within this zone, the state owns the land, but municipalities can grant concessions (concesiones) to private parties for specified uses.

A concession within the zona restringida typically:

• Has a term of 5, 10, or 20 years (renewable — but renewal is not automatically guaranteed)
• Specifies the permitted uses (residential, tourist facilities, agricultural)
• Requires payment of annual concession fees to the municipality
• Requires compliance with environmental and construction conditions
• Requires municipal approval for transfer to a new holder

The value of a concession property comes from the right to use and improve the land within the zone — not from ownership of the land itself. This distinction matters both legally and practically. A concession is an asset, but it is a more fragile asset than titled land.

The Non-Resident Restriction: Why Canadians Need a Corporation

Ley 6043 imposes a nationality and residency requirement on personal concession ownership. Foreign nationals can only hold a ZMT concession in their personal name if they have established legal residency in Costa Rica for a minimum of five consecutive years. Most Canadian buyers do not meet this threshold.

The solution is straightforward but adds complexity: a Costa Rican corporation (Sociedad Anónima or S.A., or Sociedad de Responsabilidad Limitada or SRL) can hold the concession. The corporation is a Costa Rican legal entity and is not subject to the foreign residency restriction. You, as a Canadian, own shares in the corporation — and through the corporation, you hold the concession rights.

What this structure requires:

• Corporate formation: Your abogado incorporates the S.A. or SRL in Costa Rica before the concession purchase. Typical cost: USD $1,000–$2,000 in legal and notarial fees. Timeline: 2–4 weeks.
• Registered agent: The corporation must maintain a registered agent in Costa Rica — typically your abogado or a licensed registered agent service. Annual cost: USD $300–$600.
• Annual corporate tax filing: Costa Rican corporations pay an annual corporation tax (impuesto a las personas jurídicas) — currently a tiered fee based on corporate activity, ranging from approximately USD $100–$1,000.
• UBO (Ultimate Beneficial Owner) declaration: Costa Rica requires disclosure of beneficial ownership in the Registro de Transparencia y Beneficiarios Finales (RTBF). As the Canadian shareholder, your identity is disclosed.
• Canadian tax treatment: Owning shares in a foreign corporation creates FAPI (Foreign Accrual Property Income) analysis obligations under the Canadian Income Tax Act. Your Canadian accountant needs to assess whether the corporate structure triggers any CDE (Controlled Foreign Affiliate) or FAPI reporting requirements.

These obligations are manageable — many Canadian buyers have operated Costa Rican corporations without incident for decades. But they must be set up correctly and maintained, not ignored. An abandoned or non-compliant Costa Rican corporation creates legal risk for the concession it holds.

How to Verify a Concession Before You Buy

The due diligence process for a ZMT concession property differs significantly from a standard titled property transaction. Your Costa Rican abogado must complete each of the following steps:

1. Catastral Search — Confirm ZMT Location

The Catastro Nacional (National Cadastre) holds the official surveyed boundaries of all properties in Costa Rica. Your abogado requests the plano catastrado for the specific parcel and determines whether any portion of the parcel falls within the ZMT (200m from the high-tide line) or the specific 50m public zone boundary. This is the foundational check that tells you what kind of property you are dealing with.

2. Registro Nacional — Verify Concession Existence and Status

The Registro Nacional includes the official concession registry. Your abogado searches this registry for the specific parcel to confirm: (a) A valid concession exists; (b) The concession holder is the person or entity claiming to sell it; (c) The concession term — when it was granted, its duration, and when it expires; (d) Any liens, encumbrances, or administrative proceedings registered against it; (e) Any conditions or restrictions specified in the concession decree.

3. Municipal Records — Confirm Fee Currency

The local municipality holds records of annual concession fee payments. Your abogado requests a certificación municipal confirming that all concession fees are paid current. Unpaid fees are not just a financial obligation of the prior holder — they can initiate revocation proceedings that may be underway without your knowledge. A clean fee payment history back to the concession grant date is essential.

4. SETENA and MINAE — Environmental Clearance

SETENA (Secretaría Técnica Nacional Ambiental) oversees environmental impact assessments for development in sensitive areas. MINAE (Ministerio de Ambiente y Energía) manages protected areas, wildlife refuges, and wetlands. If the property is in or adjacent to a protected area, additional restrictions on use, construction, and access may apply. Your abogado should confirm that all applicable SETENA approvals are current and that no MINAE protections affect the concession area.

5. Construction Permit Verification

All structures on a concession property must have valid construction permits issued by both the municipality and CFIA (Colegio Federado de Ingenieros y Arquitectos) for the specific buildings present. Unpermitted construction — extremely common in Costa Rican beach communities — creates risk that the buyer inherits. A demolition order can be issued against an unpermitted structure at any time, including after your purchase. Your abogado or a local engineer should walk the property and compare existing structures against the permit records.

Common Canadian Buyer Mistakes With ZMT Properties

• Trusting the listing description as legal fact.“Freehold beachfront” in a listing may be incorrect — intentionally or because the seller genuinely does not understand their own title. The catastral search is the only truth. No abogado search = no verification.
• Buying the concession personally without meeting the residency requirement. Some buyers are advised they will “get residency later” or that the residency rule is not enforced. A concession granted in violation of the residency requirement can be challenged and revoked. Always structure through a corporation if you are not a 5-year resident.
• Not checking whether the structures are fully within the zona restringida. If even one structure extends into the 50m public zone, that structure is illegal and subject to demolition. The boundary is not always obvious from visual inspection — only a professional survey confirms it.
• Assuming the prior holder's occupancy validates the concession. A seller who has been paying concession fees and living on the property for 10 years is not evidence that the original concession grant was properly made. Improperly granted concessions can be challenged even after long occupation.
• Ignoring the corporation maintenance obligations. A concession-holding Costa Rican corporation that becomes non-compliant (unpaid taxes, missed filings, unregistered beneficial owner updates) creates legal risk for the concession itself. Set up proper corporate administration from day one and maintain it annually.
• Not reading the Canadian tax implications of the corporation structure. Owning shares in a foreign corporation may trigger FAPI analysis and potentially the foreign affiliate reporting requirements. Your Canadian accountant must assess this before you structure the purchase — not after. Read our guide to Canadian tax on foreign property and consult a specialist.

What Is Safe to Buy in Costa Rica

The ZMT issue is concentrated on coastal property. The majority of Costa Rican real estate — interior properties, highland homes, properties in San José and other cities, and even coastal properties set back more than 200m from the high-tide line — is properly titled freehold land. Finding the right Costa Rican agent with ZMT expertise is the first step.

For coastal properties, the safest options are:

• Titled properties set back more than 200m from the high-tide line — verified by catastral survey showing the parcel is outside the ZMT.
• Well-documented concessions with clean title history, current fee payments, fully permitted structures, no environmental violations, and proper corporate structure from the outset.
• Properties in established resort or master-planned communities where the developer properly managed the concession framework, structures are fully permitted, and the HOA structure manages ongoing compliance.

Costa Rica is a genuinely attractive destination for Canadian buyers — stable democratic government, beautiful environment, excellent healthcare, no army, and a well-established expat community in areas like Guanacaste, the Nicoya Peninsula, and the Osa Peninsula. The ZMT issue is not a reason to avoid Costa Rica — it is a reason to do proper due diligence with a qualified abogado before committing to any coastal purchase.
