Costa Rica’s Caribbean coast is one of the most captivating stretches of real estate in all of Central America. Lush rainforest, vibrant Afro-Caribbean culture, world-class surf, and extraordinary biodiversity make destinations like Puerto Viejo, Playa Cocles, Punta Uva, and Manzanillo irresistible to buyers from around the world.

But here is what no one tells you until you are deep into a transaction: this coastline is also one of the most legally complex real estate markets in the Western Hemisphere. Buying incorrectly here does not just mean losing money. It can mean your transaction is declared legally void, with no compensation.

At Coldwell Banker Caribe, our job is to make sure you understand the full legal landscape before you fall in love with a listing. This guide covers the three major property restriction frameworks you must understand before purchasing on Costa Rica’s southern Caribbean coast.

Restriction 1: The Maritime Terrestrial Zone (Zona Marítimo Terrestre)

The Maritime Terrestrial Zone — known in Spanish as the Zona Marítimo Terrestre or ZMT — is the most widely applicable coastal restriction in all of Costa Rica. Governed by Law 6043, it applies to the first 200 meters of land measured inland from the high tide line along both the Pacific and Caribbean coasts.

Within this 200-meter band, the law divides the land into two zones:

• Public Zone (first 50 meters): This land is public domain and belongs to the Costa Rican state. No one — not Costa Ricans, not foreigners — can hold private title over this strip. Any structures here are illegal and subject to demolition.
• Restricted Zone (next 150 meters): This land cannot be privately owned in the traditional sense. Instead, it is managed through a concession system administered by local municipalities. Individuals and businesses can hold concessions — essentially long-term usage permits — but not titles.

For foreign buyers specifically, the ZMT creates an additional hurdle: foreigners who have not maintained legal residency in Costa Rica for at least five years are not eligible to hold a concession in their own name. This does not make purchase impossible, but it does require a properly structured legal arrangement, typically involving a Costa Rican corporation.

The practical implication for buyers on the Caribbean coast is significant. Some of the most photographed and marketed beachfront properties in areas like Playa Cocles, Punta Uva, and Manzanillo sit entirely or partially within the ZMT. What a seller may present as a titled property may in reality be a concession — or, in some cases, an entirely unlicensed structure with no legal standing at all.

Restriction 2: The Kekoldi Indigenous Reserve

The second major restriction layer affecting properties on the southern Caribbean coast is the Kekoldi Indigenous Reserve, also spelled Keköldi, which covers significant land area in and around Playa Cocles. This restriction is absolute, non-negotiable, and backed by Costa Rica’s Constitution and successive Supreme Court rulings.

Costa Rica’s Indigenous Law 6172, enacted in 1977, declared that indigenous territories are the collective, inalienable, and non-transferable property of the indigenous communities that inhabit them. The law is categorical: non-indigenous persons may not purchase, rent, lease, or otherwise acquire land within these reserves. Any transfer of land between indigenous and non-indigenous persons is declared legally null and void.

In 2022, Costa Rica’s Constitutional Chamber — the Sala IV — reaffirmed the law’s constitutionality, ruling that non-indigenous landholders who acquired property inside indigenous territories after 1977 are not entitled to compensation from the state. Following additional judicial rulings in 2024 and 2025, the boundaries of the Kekoldi Reserve have been formally reaffirmed to match the original 1977 demarcation — which is larger than what was informally treated as the reserve boundary in recent decades.

The real-world consequence is stark: large sections of what was previously marketed as private titled land in Playa Cocles are now legally recognized as Bribri indigenous territory, where private non-indigenous ownership is prohibited by law.

Restriction 3: The Gandoca-Manzanillo Wildlife Refuge

South of Cocles, the Gandoca-Manzanillo National Wildlife Refuge adds a third, overlapping layer of legal complexity. The refuge stretches from the Rio Cocles south to the Sixaola River at the Panama border, covering 25,910 acres of rainforest, coastline, coral reef, and wetlands.

Unlike most national parks, Gandoca-Manzanillo is a ‘mixed-use’ refuge, which theoretically allows for private land ownership and certain types of development within its boundaries. However, this nuance has led to significant legal disputes and ongoing regulatory uncertainty.

In 2025, Costa Rica’s Constitutional Court declared the refuge’s General Management Plan unconstitutional, finding that it improperly excluded over 20 hectares of forest and 165 hectares of wetlands from conservation protections. The court suspended all new concessions and permits within the refuge, while simultaneously nullifying a 2023 Environment Ministry directive that had allowed development in protected zones.

For buyers, this means that property in or adjacent to the refuge boundary faces an uncertain regulatory future, including the possibility of retroactive restriction on construction, use, and resale.

Where Can You Buy Safely on the Caribbean Coast?

The good news is that safe, legally clean real estate exists on Costa Rica’s Caribbean coast — you simply need to know where to look and how to verify.

• Hone Creek and inland Talamanca: Fully titled properties away from both the ZMT and indigenous reserve boundaries, seeing strong appreciation in 2026
• Playa Negra: Outside the Kekoldi boundaries and with strong titled inventory, currently one of the most attractive legal buy zones on the coast
• Puerto Viejo town center: Urban core properties with clear title and established legal history
• Cahuita: North of the most complex restriction zones, with titled properties and a well-established real estate market

In every case, the key is due diligence: a full title search, a CONAI certification to verify whether any part of the property falls within an indigenous reserve, a survey against the ZMT boundary, and a review of the current refuge boundary if applicable.
