If your house in Costa Rica has cracks, damp patches or leaks, the first step is not to repair it or to file a claim. It is to document the problem and find out what is causing it. A hairline crack in the plaster is not the same as a growing crack in a load-bearing wall, and a leak from a badly sealed roof is not the same as one caused by a defective concrete slab. A technical expert report (peritaje) prepared by an engineer records what is there, explains the probable cause, outlines how to fix it and estimates the cost.
With that report, you and your attorney can decide whether you have a claim against the builder, the seller or your insurer. Keep in mind that Costa Rica’s Civil Code has specific rules for each situation, with important nuances explained below, and deadlines apply. If you suspect a serious defect, talk to a local attorney as soon as possible. This matters even more if you bought from abroad or spend part of the year outside the country, because problems can go unnoticed for months.
Not every crack is a defect: warning signs worth checking
Many cracks are cosmetic, caused by normal shrinkage of the plaster or temperature changes. Others can point to something deeper. These signs justify a technical inspection:
- Diagonal cracks running from the corners of doors and windows.
- Cracks that grow or widen over time, or come back after being patched.
- Doors and windows that suddenly stick.
- Uneven floors, or tiles that lift or crack in a line.
- Rising damp at the base of walls, or stains that appear after every heavy rain. In the rainy season this shows up fast.
- Drips and stains on ceilings, especially under concrete slabs, gutters or roof joints.
- Mold, a musty smell or paint that bubbles and peels.
- Cracks in retaining walls or in the ground around the house, common on hillside lots.
None of these signs proves a construction defect on its own. What they tell you is that you need a diagnosis before spending money on repairs that may not address the cause.
When not to wait
If a crack is opening quickly, you hear cracking sounds, walls or beams look deformed, or the problem appeared after an earthquake or a landslide, put safety first: leave the affected area and, if there is any risk, call 9-1-1, Costa Rica’s emergency number. The inspection comes later.
What a construction defect inspection is
It is a technical study, different from an appraisal. An appraisal answers “what is the property worth?”; a defect inspection answers “what is failing, why, and what will it cost to fix?”. Depending on the case, it may include:
- Site inspection with photographs and measurements of cracks, slopes and damp areas.
- Document review: plans, building permit, construction contract, specifications and site logbook, if they exist.
- Probable cause of the damage: design, workmanship, materials, soil, lack of maintenance or an external event.
- General repair approach and an estimated repair budget at current prices.
- Effect on value, when you need to know how much less the property is worth with the defect.
Some cases need additional studies by other specialists, such as a soil study or lab tests. A good report says so plainly instead of guessing.
Three different situations: you built it, you bought it, or an event damaged it
How you can claim depends on how you came to own the house. Here is what the law says in general terms; how it applies to your case is for your attorney to decide.
1. You hired someone to build the house
If you hired a builder or a design professional to build your home, the Civil Code has rules on the builder’s liability in its chapter on fixed-price construction work (obras por ajuste o precio alzado, articles 1183 onward):
- Article 1185: architects or contractors who took charge of constructing a building or a bridge, whether under a fixed-price contract or not, are liable for its total or partial loss, whether it comes from a construction defect or a soil defect, and that liability lasts five years from the acceptance of the work. It is enough for the architect to have directed the work for this rule to apply to him or her.
- Article 1186: if the contractor built from plans drawn by an architect chosen by the owner, liability is split: the contractor answers for faulty workmanship or poor materials, and the architect for defects in the plans.
- Article 1187: the contractor cannot escape that liability by arguing that he warned the owner about soil defects, construction risks or poor-quality materials.
Whether a specific crack or leak falls under these rules, and which other deadlines or remedies apply (including what your contract says), is a legal question. That is why it matters that the technical report separates design defects from workmanship and materials defects.
2. You bought the house already built
This is where many foreign buyers may be surprised, because the starting point can be narrower than what they expect from other countries. Article 1082 of the Civil Code states that a sale cannot be annulled because of hidden defects in the property, unless those defects involve an error that voids consent or the contract provides otherwise.
In practice, what was agreed in the deed or purchase agreement, and how the purchase was negotiated, carries a lot of weight. If you bought from a developer or a company that sells homes as a regular business, ask your attorney whether Costa Rica’s consumer protection law, Law 7472 (Ley de Promoción de la Competencia y Defensa Efectiva del Consumidor), also applies. Either way, the expert report helps show that the defect exists, how long it has probably been there and what it will cost to fix.
3. The damage comes from an event
If the cracks or leaks appeared after an earthquake, a flood, a landslide or construction work next door, the case looks more like an insurance loss than a construction defect. What your policy covers depends on its terms. We explain this in our guide to property damage appraisals and on our insurance appraisals service page.
What to do, step by step
- Document from day one. Take dated photos with a ruler or a coin next to each crack for scale. Mark the ends of each crack and the date in pencil: if it grows, you will see it.
- Do not patch or repair before documenting. You can take urgent steps to stop the damage from getting worse (cover against water, shut off a leak), but photograph before and after and keep the receipts.
- Gather the paperwork: construction or purchase contract, deed, plans, building permit, invoices, written warranties, and emails and messages with the builder or seller.
- Notify the builder or seller in writing, describing the problem. Ask your attorney how to do it so you do not weaken your position.
- Order the technical inspection to learn the cause, the repair and the cost.
- Talk to an attorney early. Deadlines to claim are limited and depend on the type of case.
If you have not bought yet: inspect before you sign
The best way to avoid a hidden-defect dispute is to catch problems first. If you are buying a resale home or a unit in a new project, ask for a technical inspection in addition to the appraisal: the appraisal estimates value, while the inspection looks for visible problems in the structure, plumbing, electrical systems and moisture. No inspection can guarantee there are no hidden defects, but it lowers the risk and gives you leverage to negotiate the price. See our due diligence checklist for real estate in Costa Rica.
What the report adds in a negotiation or a lawsuit
Many cases are settled by negotiation: the builder repairs, the seller agrees to a price reduction, or the insurer adjusts its offer. A technical report with photos, cause and budget gives you an objective basis for that conversation.
If the case goes to court, the report you submit is presented as evidence offered by one party: it supports your position, but the court decides how much weight to give it and may appoint its own expert. Our judicial appraisals page explains how we work in legal proceedings.
Frequently asked questions
Does every crack mean the house was badly built? No. Many cracks are cosmetic. Their shape, location and whether they grow are the clues that tell them apart; an engineer makes the diagnosis on site.
How long do I have to file a claim? It depends on the case. Article 1185 of the Civil Code says that a contractor’s liability for the total or partial loss of a building due to construction or soil defects lasts five years from acceptance of the work. That is the period the rule covers; the deadline to actually file a claim is a separate question, and other rules and deadlines may apply depending on your contract and situation. Confirm it with a Costa Rican attorney as soon as possible.
Does my insurance cover cracks and leaks? It depends on the policy and the cause. Damage from a covered event is usually treated differently from wear and tear or a construction defect. Check the terms with your insurer or broker.
Can you inspect my house? Every case is different. Tell us what you are seeing and we will let you know whether we can take it on and what the report would cover.
How much does it cost? It depends on how extensive the problem is, the size of the home and whether documents need to be reviewed or additional studies coordinated. The price is set in the quote.
