Building a house in Costa Rica starts long before construction. You need a land-use certificate, proof of water and electricity, plans drawn by a professional registered with the CFIA, the national association of engineers and architects, a workers’ insurance policy and a municipal permit, with a construction tax of up to 1% of the value of the work. Houses must meet the country’s seismic code, which is why most are still built of reinforced concrete block. What you’ll pay varies so widely by location and finish that official figures are only a rough guide, so get detailed quotes from contractors before you commit.
| Before you buy the lot | Land-use certificate, water availability, electricity, road and river setbacks |
|---|---|
| Plans | Drawn and signed by a CFIA-registered architect or engineer and filed in the CFIA’s online system |
| Permit | Issued by the municipality; workers’ risk insurance from INS required |
| Construction tax | Up to 1% of the value of the work, paid to the municipality |
| Environmental review | Generally not needed for buildings under 1,000 m² (10,800 square feet) |
| Seismic code | 2010 code, revised 2014; a new 2025 edition awaits a government decree |
| Official value guide | Hacienda’s 2023 appraisal values for concrete homes range from about â‚¡260,000 to â‚¡1.8 million per m² (about $570 to $4,000) |
Check the lot before you buy it
A beautiful lot you can’t build on is the most expensive mistake in Costa Rica real estate. Before you sign an option, get the municipality’s land-use certificate, the certificado de uso de suelo, which says what can be built there. Confirm that water and electricity can reach the lot, because the water availability letter is now the hardest document to get. Our guide to water for a new home explains the options. Check the registered survey plan, any setback line from a national road set by MOPT, the public works ministry, and the INVU setback from any river or stream. Steep land, protected forest and springs all reduce the area you can build on.
How the building permit works
Only a professional registered with the CFIA, the Colegio Federado de Ingenieros y de Arquitectos, can draw and sign construction plans, and the plans are filed through the CFIA’s online APC system, which routes them to the institutions that review them. You also need a workers’ risk insurance policy from INS, the state insurer, and then the municipality issues the permit. Municipalities charge a construction tax of up to 1% of the value of the work under the Urban Planning Law, and each canton has its own checklist, so ask for it at the start.
Most single-family homes don’t need approval from SETENA, the environmental agency. Under rules in force since August 2023, buildings under 1,000 square meters generally need no environmental review, though a simplified review applies in environmentally fragile areas, and earthworks of 1,000 cubic meters or more still need review.
Building without a permit is common and risky. When the CFIA inspected 5,934 construction sites in 2025, it found that 20% had no permit. Unpermitted work can be stopped, fined or ordered demolished, and it causes problems when you sell. If you are buying an existing house, ask for the approved plans and permits for the original house and any additions, and compare them with what was built. Our guide to property measurements explains why the advertised size often isn’t what the plans show.
What it costs to build
There is no official current cost-per-square-meter figure for a new house, and published numbers measure different things. Hacienda’s appraisal manual, which municipalities use to value property for tax, put concrete homes at about â‚¡260,000 per square meter for the most basic type up to â‚¡1.8 million for the most luxurious, based on March 2023 prices. That is roughly $570 to $4,000 per square meter, or $53 to $375 per square foot, at about â‚¡456 to the dollar, with mid-range homes around â‚¡425,000 to â‚¡545,000 ($930 to $1,200) per square meter. The values declared on permit applications, which the national statistics institute INEC compiles, are lower still, and the Costa Rican Chamber of Construction cautions that they don’t reflect what homes actually cost to build.
Treat those figures as a starting point. Location matters, since materials and labor cost more on the coast and in remote areas, and so do slope, foundations, roof style, ceiling height, windows and finishes. On top of construction, budget for the professionals’ fees, permits and the construction tax, utility connections, a driveway and retaining walls, and furniture and appliances. A large new home can also cross the threshold for the luxury home tax, which is set on the value of the construction; once a home crosses it, the land is taxed too.
The seismic and electrical codes
Costa Rica sits in one of the most earthquake-prone regions of the Americas, and every structure must meet the Seismic Code. The edition in force is the 2010 code, revised in 2014. The CFIA approved a new 2025 edition, which adds wind loads for the first time and updated seismic hazard data, but as of September 2026 it was still waiting for the executive decree that puts it into effect. Your engineer must design to whichever code applies when you file. The electrical code is based on the 2020 U.S. National Electrical Code.
That is why reinforced concrete block remains the standard for houses, often with drywall for interior walls in condominiums, light-gauge steel or wood roof framing and metal roofing, sometimes topped with clay tile. Finishes have converged with North American standards over the past three decades, from granite counters to glass showers, but many homes, especially older and rural ones, still have tiled-only floors, cold-water sinks and instant electric shower heads. When you compare houses for sale, compare the construction and finishes as well as the size and location.
Hiring and managing the build
- Check that your architect or engineer is registered and in good standing with the CFIA.
- Sign a written contract that sets the price, what is included, the schedule, the payment stages and who supervises the work.
- Tie payments to completed stages, not dates, and keep a retention until the end.
- Make sure the professional in charge inspects the work and records it in the CFIA’s construction logbook.
- Keep copies of the approved plans, the permit and every change order. You will need them when you sell or insure the house.
- Get a final inspection before the last payment, and consider an independent home inspection.
