How the 49% cap works, and what to do when a building is full
The 49% foreign ownership quota is the single rule that shapes every foreign condo purchase in Thailand. It determines whether you can buy the unit you want in your own name, what paperwork your bank transfer needs to carry, and what your fallback options are if the building you've fallen in love with has already filled its foreign allocation. Here's how the quota actually works, facet by facet.


Up to 49% of a building's total saleable floor area can be foreign-owned; the remaining 51% must be held by Thai nationals or Thai entities. The cap applies per building, not city-wide or nationally, so it's worth checking each building individually.
Ask the building's juristic person (for a completed project) or the developer's sales office (for an off-plan launch) for the current foreign-quota status, and get the answer in writing before you pay a reservation deposit. A local licensed agent familiar with the building can often confirm this faster than a general inquiry.
You generally have three options: wait until a current foreign owner sells to a Thai buyer and frees up space, pursue a Thai-quota unit through a compliant Thai company or co-owner structure (get legal advice first), or choose a different building that still has quota remaining. Many buyers find comparable units in nearby buildings without significant compromise.
No. The 49% quota applies only to registered condominium units. Foreigners cannot directly own land in Thailand at all, regardless of any quota, and typically use a registered long-term lease to occupy a house or land-based property instead.

The quota caps foreign ownership at 49% of a condominium building's total saleable floor area — not 49% of the number of units, and not a nationwide or city-wide limit. It's calculated per building, so a small building can fill up fast while a large one still has room. Land, houses built on land, and townhouses aren't covered by this rule at all; it applies only to registered condominium units.

The juristic person (for completed buildings) or the developer's sales office (for off-plan projects) can tell you the current foreign-quota status — ask before you pay a reservation deposit, not after. For extra assurance, request written confirmation of the remaining percentage, since verbal quotes from a sales agent can be optimistic. A licensed real estate agent working the building regularly is often the fastest route to an accurate answer.

To register as the foreign owner, the full purchase amount must be remitted from abroad in foreign currency and converted to Thai baht by the receiving Thai bank — money already sitting in a Thai baht account doesn't qualify. The bank documents this with a Foreign Exchange Transaction (FET) form for larger transfers, or an equivalent credit advice letter for smaller ones. The Land Department will ask to see this on transfer day, so keep the original.

Once a building's 49% is allocated, no more units can be sold to foreign freehold buyers until an existing foreign owner sells to a Thai buyer, freeing up space. Your realistic options are: wait for a unit to free up, buy a unit under the Thai quota (which requires a compliant Thai company structure or a Thai co-owner — get legal advice before going this route), or look at a different building with quota remaining.

Since foreigners can't directly own land at all, and a condo quota can fill up, a registered long-term lease is the common workaround for houses, villas, and land-based property — and sometimes for a condo in a full building. These leases are commonly structured for 30 years with renewal options, but enforceability of a renewal isn't guaranteed by law; it depends entirely on what's written into the registered lease document, so have a lawyer review it before signing.

A freehold condo within quota is registered in your name on the title deed with no expiry — you can sell, will, or mortgage it like any owned asset (subject to a future foreign buyer needing the same FET process). A leasehold is a contractual right to use the property for a fixed term; you don't hold title, so resale means assigning the remaining lease term, typically a smaller and slower market than a freehold sale.

The most common trip-ups: paying part of the purchase price with baht already inside Thailand instead of a fresh foreign remittance, relying on a verbal quota assurance instead of a written one, and signing a Sale and Purchase Agreement without a lawyer reviewing what happens if the quota fills before your transfer date. Any of these can delay or block registration at the Land Department, so build in time to fix paperwork issues before your target transfer date.
