Buying a lot in Guanacaste is not the same as buying a house that is already built. A house already has a roof, utilities, and permits. A lot is only a good buy if you can own it, reach it, get water to it, and build on it.
This guide covers those four questions. It is general information from sixteen years on this coast, not a legal opinion. Your Costa Rican attorney should review the specific property.
If you are buying a finished home, start with the safe-buying guide and the due-diligence checklist. A lot needs those same steps, plus the four checks below.
The purchase process, from offer to registration, is in the buying guide. Closing costs on a titled purchase are in the closing-costs guide. How you hold the property is in the tax and legal guide.
Ownership
A deed and a lease are not neighbors
Title on a Guanacaste Lot
Titled land and a concession are not the same thing. Titled land is ownership, recorded on a folio at the Registro Nacional. A concession in the Maritime Zone is a municipal lease on coastal land the state did not sell. See the concession page and the maritime-zone guide for the legal details, including foreign-ownership limits. Have your attorney confirm the rules for the parcel you are buying.
Do not rely on a community name or a beachfront sales pitch. Even in titled communities like Reserva Conchal, Hacienda Pinilla, Las Catalinas, and the residential areas of Flamingo, part of a lot can still fall in the restricted zone. Ask for the folio number. If someone says beachfront is “as good as titled,” stop until your lawyer has that number.
Have your attorney check three things:
1. The seller is the registered owner, or has authority to sign for that owner. 2. The liens, easements, and notes on the folio match what you were told. 3. The survey (plano catastrado) matches the land you walked.
The registry will not show a fence in the wrong place, someone living on the lot, or a filing that comes in after you check. That is why the due-diligence checklist includes a surveyor on the ground and a second registry check on signing day. A caretaker, photos, and paid taxes are useful. They do not replace the folio.
Getting there
The road you drove is not the right you own
Legal Access
A road your car just used is not the same as a legal right to use it. Some lots are reached by crossing a neighbor’s land, with nothing recorded in favor of the lot for sale.
Your attorney and surveyor should answer this: Does the parcel touch a public road? If not, is there a registered easement (a servidumbre) that gives this lot the right to cross the land in between? A handshake, a WhatsApp message, or a promise that “the developer will grant it at closing” is not access.
Also think about construction. A path that works for a car or golf cart may not work for concrete trucks, lumber, or a well rig. Legal access has to be on paper before you send a deposit you cannot get back. The safe-buying guide explains the escrow rule. Use it.
Water
No current letter, no building permit
Water on the Lot
Water stops more coastal lots than title does. A building permit needs a current water-availability letter (carta de disponibilidad de agua) from AyA or from the ASADA that actually serves the property. An old letter does not count. A promise to get one later does not count. The due-diligence checklist says the same thing for houses. On a vacant lot, missing water can stop the whole project.
Confirm which system issued the letter, and that the letter names this lot. AyA is the national water utility. An ASADA is a local water association. A letter from the wrong one does not help. Inside a master-planned community, confirm the water solution covers the lot in your offer, not just the neighborhood entrance or the next phase.
A private well usually needs its own concession, and it is a weak substitute for a letter you can build with. Treat it as a question for your attorney and a driller, not as a solved problem because the listing said “water possible.”
If you remember one thing: no current water letter, no building permit.
Buildability
The stack between dirt and a house
Whether You Can Build
You need more than title to build a house. Start with the municipality’s land-use certificate. It says what this parcel is allowed to be. If the listing calls it a home site and the certificate says something else, it is not a home site yet.
Then look at the land. Some Guanacaste lots are flat. Others are hillsides that need retaining walls, drainage, and a road construction crews can use. A steep lot can still make a good house. It is rarely a cheap house. An architect and a local engineer should review it.
Confirm power with the utility that serves the address. Septic or sewer depends on the soils and the permit. Internet matters if you will work from the house, but it does not replace water.
The permit steps are on the pre-construction page: a land-use certificate, the water letter, environmental review from SETENA when required, CFIA-stamped plans, and a municipal permit. That page has the time ranges. SETENA can add months. A lot in the Maritime Zone usually faces a longer environmental review than a titled lot up the hill. Your attorney can tell you which process applies.
Setbacks, height, and how much of the lot you can cover come from municipal rules and, inside a community, from the association’s design manual. Reserva Conchal and other gated communities will not approve every house that fits on the dirt. Read the manual before you budget a house the association will not allow. HOA costs are on the club and HOA guide. They are a carrying cost, separate from the lot price.

The Order I Use
When a buyer asks me to look at land, I use this order:
1. The folio, and whether it is titled land or a concession, with an attorney who represents only the buyer. 2. A survey of the ground, including registered access to a public road. 3. A current water letter for this parcel. 4. The land-use certificate, plus a clear look at slope, construction access, and permits.
Only then does a house plan deserve a budget. If any of these four is still open, keep the deposit refundable, or do not send it yet. The safe-buying guide explains where money should sit. The how-to-buy FAQ covers the purchase sequence.
A lot can be the right purchase. Some of the best homes on this coast started as vacant land. The ones that go wrong are the ones where the view answered questions the folio, the road, and the water letter had not answered yet.
If you have a parcel in mind, send me the listing or the folio and tell me whether you want a house, land to hold, or a build you will manage from abroad. I will tell you which of the four questions is still open before anyone asks you to wire.
