How to Do Due Diligence When Buying Property in Costa Rica

Due diligence when buying property in Costa Rica means independently verifying a property's legal status, physical condition, and infrastructure access before you commit any money. It is not optional. The burden of verification falls entirely on the buyer. Not the seller. Not the broker. Not the notary.

Why Due Diligence Is Different in Costa Rica

Most foreign buyers arrive with assumptions based on how real estate works in the United States or Canada. Those assumptions can be expensive in Costa Rica.

There is no centralized MLS. There is no standardized buyer protection law. Real estate agents in Costa Rica are not required to hold a license. The same agent can legally represent both buyer and seller in a single transaction. That is dual agency, and it would be illegal or tightly regulated in most US states.

The broker representing you may be financially motivated to close the deal, not to protect your interests.

Independent due diligence is the only mechanism that protects you.

Step 1: Title Search Through the National Registry

The first and most critical step is a title search through Costa Rica's National Registry (Registro Nacional). Every titled property in Costa Rica is recorded there.

A proper title search confirms:

• Who legally owns the property
• Whether any liens, mortgages, or encumbrances exist
• Whether any legal disputes or court cases are attached to the property
• Whether the property boundaries in the registry match the physical survey on the ground
• Whether the seller has full legal authority to transfer ownership

Many properties in Costa Rica are owned by holding corporations (Sociedad Anónima or SRL) rather than individuals. If that is the case, your due diligence must include a review of the corporate documents: shareholder structure, legal standing, and any outstanding corporate tax obligations. Failure to file annual shareholder declarations in Costa Rica can result in penalties of up to $79,000. That obligation transfers to the new owner.

The title search must be conducted by a licensed Costa Rican attorney. Do not use an attorney recommended by the broker. Hire one independently.

Step 2: Cadastral Map Verification

The cadastral map (plano catastrado) is the official boundary survey of the property registered with the National Registry. It is frequently skipped and frequently causes problems.

Your due diligence must confirm:

• The cadastral map is current and matches the National Registry record
• The physical boundaries on the ground match the official survey
• No overlap exists with neighboring properties, public roads, or waterways
• The registered size matches the size being sold

Land in Costa Rica, particularly in rural and coastal areas, was often farmland before it became residential real estate. Precise boundaries were never established. Discrepancies between the registry and what physically exists on the ground are common. They can create serious legal complications after purchase.

Step 3: Maritime Zone Verification

More foreign buyers have gotten burned here than anywhere else in the transaction.

Costa Rica's Maritime Zone Law (Ley 6043) designates a 200-meter strip along the entire coastline from the high tide line as a restricted zone:

• First 50 meters from high tide: Public beach. Cannot be privately owned or developed by anyone.
• Next 150 meters (restricted zone): Cannot be owned in fee simple. Can only be held under a government concession granted by the local municipality.

Foreigners cannot hold more than 49% ownership in a maritime zone concession. A Costa Rican citizen or entity must hold the remaining stake.

Concessions are not permanent ownership. They are time-limited licenses, typically 20 years, granted by the municipality and subject to renewal. A concession can be revoked if the terms are violated.

Only 5% of Costa Rica's beaches have titled land extending to the 50-meter line. The vast majority of beachfront listings involve concession property.

Before you make any offer on a coastal property, verify whether it falls within the maritime zone, whether a valid concession exists and is properly registered, the concession terms and expiration date, permitted uses, and the ownership structure.

Step 4: Municipal Verification and Zoning

Every municipality in Costa Rica has a regulatory plan (Plan Regulador) that governs land use. That plan is separate from whatever a broker tells you the property can be used for.

Uso de Suelo (Land Use Certificate)

This document from the municipality confirms what the property is legally zoned for: residential, commercial, agricultural, conservation, or mixed use. Never assume. A property that looks suitable for vacation rental may be zoned agricultural only.

Construction Permits

Any existing structure on the property must have proper construction permits approved by the municipality and the Federated College of Engineers and Architects (CFIA). Unpermitted construction is a significant liability. You inherit it when you buy the property.

Property Tax Status

Confirm there are no outstanding property tax arrears with the municipality. This obligation transfers to the new owner.

Environmental Restrictions

Costa Rica has robust environmental protections. Properties near rivers, national parks, protected wetlands, or buffer zones may face severe development restrictions. An environmental overlay check through the municipality and SINAC (National System of Conservation Areas) is essential for rural and jungle properties.

Step 5: Water Rights Verification

Water access in Costa Rica is not automatically included with a property purchase. You need to verify it independently.

There are three main sources of legal water supply:

• AyA (Instituto Costarricense de Acueductos y Alcantarillados): The national water authority, serving urban and suburban areas
• ASADA (Asociaciones Administradoras de Sistemas de Acueductos y Alcantarillados): Rural water associations managing local water systems
• Private wells: Legal if properly permitted through SENARA (National Groundwater Service)

For any property you are considering, you must obtain a carta de disponibilidad de agua (water availability letter) from the relevant authority. It confirms the property has a legal right to a specific water supply volume.

Without this document, you cannot obtain a building permit. Without a building permit, you cannot legally develop the property.

Relying on a seller's verbal assurance of water access is one of the most common mistakes foreign buyers make in Costa Rica. It is also one of the most expensive.

Step 6: Physical Site Inspection

Legal due diligence tells you what the documents say. A physical site inspection tells you what is actually on the ground.

A thorough physical inspection should cover:

• Property access: Is there legal, year-round road access? Who is responsible for road maintenance?
• Topography and soil: Is the land suitable for the intended construction? Soil instability and drainage problems can make a property undevelopable.
• Flood and landslide risk: Costa Rica's rainy season is significant. Properties in valleys, near rivers, or on steep hillsides require risk assessment.
• Existing structures: Condition of any buildings on the property, including electrical systems, plumbing, and foundations.
• Neighbor interviews: What do adjacent landowners know about the property's history, boundary disputes, or issues with the seller?
• Utility infrastructure: Physical confirmation of electricity connection, water supply, and internet availability.

You cannot do this part remotely. It requires someone on the ground who knows what to look for. Not the seller. Not the broker. Not someone who flew in for a day.

Step 7: HOA and Condominium Review

If the property is within a gated community or condominium development, an additional layer of due diligence applies.

Review all HOA covenants, restrictions, and bylaws before making any offer. These can include:

• Architectural restrictions that limit what you can build
• Short-term rental restrictions that prohibit Airbnb-style use
• HOA fee amounts and current financial health of the association
• Any pending assessments or disputes within the community

A property in a community with financial problems, pending litigation, or restrictive covenants that conflict with your intended use is a liability, regardless of how attractive the price or location appears.

How Long Does Due Diligence Take?

A standard due diligence period in Costa Rica is 30 days. Write it into the purchase agreement as a contingency. Your deposit should be fully refundable if any due diligence item returns an unsatisfactory result.

More complex transactions, like properties with concession issues, corporate ownership structures, or rural locations with water and access complications, may require 45 to 60 days.

Do not let a broker or seller pressure you into shortening the due diligence period. Any seller who resists proper due diligence is a red flag.

What Does Due Diligence Cost?

Expect to budget for:

• Independent attorney fees: $1,500 to $3,000 depending on complexity
• Survey verification: $300 to $800
• Physical inspection and reports: $500 to $2,000 depending on scope

This is a very small percentage of any property purchase price. Skipping it to save money is one of the most expensive decisions a foreign buyer can make in Costa Rica.

Frequently Asked Questions

Do I really need due diligence if the broker says the property is clean?

Yes, always. The broker is paid by the seller and has no legal obligation to verify the property's condition on your behalf. "Clean" means nothing without independent verification through the National Registry.

How do I find a good independent attorney in Costa Rica?

Look for a bilingual attorney who advertises directly to foreign buyers and has no relationship with the broker you are working with. Avoid attorneys recommended by brokers. Ask for references from past foreign clients.

What is the biggest mistake foreign buyers make in Costa Rica?

Trusting a broker's assurance that a property is fine without conducting independent verification. The second biggest mistake is buying beachfront property without verifying maritime zone status.

Can I do due diligence remotely from the US or Canada?

The legal portion (title search, registry checks, zoning verification) can be done by your attorney remotely. The physical site inspection cannot. Someone must visit the property, inspect existing structures, interview neighbors, and verify physical access and utilities in person.

What happens if I skip due diligence and buy a property with problems?

You inherit those problems. Liens, unpermitted construction, invalid water rights, maritime zone violations. All become your responsibility the moment the deed transfers. Costa Rican courts are slow. Prevention is far more effective than litigation.

What is a water concession and why does it matter?

A water concession is a legal permit granting the right to extract a specific volume of water from a source. Properties relying on a well without a valid SENARA concession may not be able to obtain construction permits. Always verify the water source and its legal status before purchase.

How is due diligence different for a condo versus a house versus land?

Condos require additional review of HOA documents, financials, and any short-term rental restrictions. Land purchases require more extensive environmental and zoning review, soil testing, and utility availability confirmation. Houses require physical inspection of existing structures in addition to all standard legal checks.

Should I use the same attorney as the seller?

Never. This is a direct conflict of interest. Always hire your own independent legal representation.
