A foreigner can own a condominium in Thailand outright — freehold, in their own name, forever — but only inside one crucial limit: the 49% foreign-ownership quota. Get the quota right and the rest of the purchase is straightforward. Get it wrong and the deal can't register. Here's exactly how the quota works, why land is different, and how to check a building before you commit. Unbiased, never paid placement.
Foreigners can collectively own up to 49% of the floor area of any condo building, freehold, in their own names. Land — and so most houses and villas — can't be owned freehold by a foreigner. Before you pay, confirm in writing that the building still has foreign-quota space, bring your money in from abroad for the FET, and know that your unit only stays on the foreign side if you sell to another foreigner.
The Thai Condominium Act lets non-Thais own condo units, but caps the total: across any single building, foreigners may own no more than 49% of the combined saleable floor area. The other 51% stays Thai. The key detail most buyers miss is that the quota is measured by floor area, not unit count — and it's tracked per building, not per project or per developer. A 200-unit tower can have plenty of unsold units while its foreign 49% is already taken. That's why "are there units available?" and "is there foreign quota available?" are two completely different questions.
If a unit fits inside the 49%, you can take it freehold: a perpetual title in your own name, registered at the Land Office as the blue unit title deed. If the quota is full, the usual fallback is leasehold — a registered long lease (commonly 30 years) on the unit. The two are not the same asset:
Thai law reserves freehold land for Thai nationals and Thai-majority companies. Because a house or villa sits on land, a foreigner can't own one freehold either; those deals run on a registered lease, usufruct or superficies, or by buying the structure while leasing the ground beneath it. A condominium is the elegant exception: the land under the building is owned in common by all unit owners, so as a foreign condo owner you hold the unit and a share of the common property — without ever owning land directly.

Quota is the single most common reason a foreign purchase falls over — and it's entirely avoidable with one question asked early. Before any deposit:

To register foreign freehold, the Land Office needs proof the purchase money entered Thailand from abroad in foreign currency — the Foreign Exchange Transaction (FET) form. Remit the funds in your home currency (don't pre-convert to baht offshore), tell the bank the purpose is to buy a condominium, and have them issue the FET in the buyer's name. Keep it safe afterwards: you'll need it again to repatriate the proceeds when you sell. Estimate the all-in cost with our purchase-cost calculator.
The 49% is live, not fixed at launch. Sell your foreign-freehold unit to another foreigner and your slice of the quota transfers with the sale — the unit stays on the foreign side. Sell to a Thai buyer and that floor area returns to the Thai 51%, which can quietly tighten foreign availability in the building. None of this is a problem if you buy where foreign demand is strong; it's simply worth knowing your exit market before you buy. Compare areas with our area comparison and best-for-investment tools.
