The 49% Foreign Quota Explained: How Foreigners Own Condos in Thailand

What the quota actually is

Under Thailand's Condominium Act, foreigners may collectively hold freehold title to no more than 49% of the total saleable floor area of a condominium building. The remaining 51% must be Thai-owned. The limit applies per building (strictly, per condominium juristic registration), not per project or per developer — a two-tower project has two quotas.

Note that the quota is measured by area, not by unit count. A foreigner buying a large penthouse consumes more quota than one buying a studio.

Why the quota exists — and why it's good for you

The rule reflects a national policy that land and most housing remain majority Thai-owned, while still giving foreigners a genuine, registrable form of property ownership. For investors the quota cuts both ways: it constrains supply of foreign-ownable stock in popular buildings, which supports resale values of foreign-quota units — a foreign buyer reselling to another foreign buyer is selling a scarce thing.

How to verify a condo building's foreign ownership quota

The condominium juristic person (the building's management entity) maintains the official ledger of foreign ownership, and the Land Office checks it at every transfer. Before you reserve an off-plan unit, ask the developer for written confirmation of the remaining foreign quota allocated to your unit. For off-plan projects the developer manages quota allocation across its sales pipeline — reputable developers will commit in the contract that your unit transfers as foreign freehold.

• ✓Get remaining-quota confirmation in writing before reserving
• ✓Make the contract conditional on foreign-freehold registration
• ✓At transfer, the Land Office independently verifies the quota

What happens if a building's 49% foreign quota is already full?

In buildings where foreign demand is strong, the 49% can sell out. Developers then typically offer remaining units to foreigners as leasehold: a registered 30-year lease, sometimes marketed with renewal options. Be clear-eyed about this: renewal promises beyond the registered 30 years are contractual undertakings, not property rights, and leasehold condos resell at a meaningful discount with a shrinking remaining term.

For most investors, the practical rule is simple: buy freehold within quota, and treat quota-full buildings as a signal to look at the next project — Bangkok rarely lacks alternatives.

Freehold vs leasehold: the distinction that decides what you actually own

Freehold and leasehold are not two flavours of the same thing. Freehold is ownership: an indefinite right, registered in your name on the unit's title at the Land Office, that you can sell, mortgage or leave to your heirs. Leasehold is a registered tenancy: a right to use the unit for a fixed term, after which it reverts to the owner. Both are legitimate, both are registrable, and they are priced as if they were far closer together than they are.

The practical difference is what happens to value over time. A freehold unit's value tracks the market. A leasehold unit's value tracks the market minus a clock that never stops — every year that passes is a year of remaining term gone. A 30-year lease with 8 years left is not a slightly cheaper apartment; it is a different asset, and the pool of buyers willing to take on the tail end of someone else's lease is thin. This is why a leasehold unit sold at a small discount to the freehold price is usually a bad deal rather than a bargain.

So the first question on any unit marketed to foreigners is not the price. It is: is this freehold within the 49% quota, or is it leasehold? Get the answer in writing, before the deposit.

• ✓Freehold: indefinite, registered on the unit title, resells to anyone
• ✓Leasehold: fixed term, reverts to the owner, resale value decays with the remaining term
• ✓A leasehold priced near freehold is the warning sign, not the discount

The "30+30" trap — and why a 99-year lease isn't a thing

Section 540 of the Civil and Commercial Code caps a registered lease of immovable property at 30 years. That is the whole of what can be registered as a real right. Anything longer that you see advertised — "30+30", "30+30+30", "90 years", "99 years" — is 30 registered years with contractual renewal promises stacked on top.

Here is the part that is routinely explained wrong, including by people acting in good faith. It is true that a registered lease survives a change of ownership: under section 569, if the property is sold the lease carries over and the new owner is bound by it. People reason from this that their renewal option is equally safe. It is not. The lease is a real right that runs with the property; the renewal option is a personal contractual right against the specific person who granted it. A successor in title inherits the lease but does not inherit the promise to renew it. If the developer sells the freehold, or is wound up, or simply declines when the time comes, your remedy is a claim for breach of contract against whoever gave the promise — not a right to stay.

Which means a "30+30" is marketed and priced as a 60-year interest while only the first 30 years are secured as a property right. That gap is the single most expensive misunderstanding available to a foreign buyer in Thailand, and it is most often sold to people in their 60s and 70s for whom the first 30 years look like enough.

The "99-year lease through a Thai company that owns the building" variant does not escape the cap either — the same 30-year limit applies to the lease the company grants you. It also adds a second problem on top: if the Thai company exists mainly to hold property on a foreigner's behalf, its Thai shareholders may be nominees, which is prohibited. Under the Land Code the consequences run to forced disposal of the land and criminal exposure for the Thai nominees, and the structure can unwind at the worst possible moment. A structure whose safety depends on nobody ever looking closely is not an ownership plan.

• ✓CCC s.540 caps a registered lease at 30 years — there is no 99-year lease
• ✓CCC s.569 keeps the lease alive on a sale; it does not carry the renewal option
• ✓A renewal option binds the person who gave it, not a successor in title
• ✓Nominee-shareholder company structures risk forced disposal under the Land Code

Quota strategy for off-plan buyers

Off-plan buying interacts with the quota in a useful way: at launch, the full 49% is available, so early buyers get first claim on foreign quota in buildings likely to fill it. In districts popular with foreign investors, this is one more reason the launch phase is the right time to act — beyond the pricing curve itself.

BaanScope tracks tenure as a field on every project, and reports it only where the developer states it — which today is very few. That is deliberate: assuming "freehold" because a unit is a condominium is exactly the error this section is about. Where we cannot verify it, we show nothing and you should ask.

Frequently asked questions

Can a foreigner own 100% of a condo unit in Thailand?

Yes — the 49% limit applies to the building's total saleable area, not to individual units. Your unit is 100% yours, freehold, registered in your name, as long as total foreign ownership in the building stays within 49%.

How do I verify a condo building's foreign ownership quota before buying?

Ask the developer (for off-plan) or the condominium juristic person (for completed buildings) for written confirmation of remaining foreign quota. Your lawyer should verify it before the contract deposit, and the Land Office checks it definitively at transfer.

What happens if a condo building's 49% foreign quota is already full?

Developers typically offer remaining units to foreigners as leasehold — a registered 30-year lease, sometimes marketed with renewal options that are contractual promises rather than guaranteed rights. For most investors the practical move is to buy freehold within quota elsewhere: a quota-full building is a signal to look at the next project, not a reason to accept leasehold at a freehold price.

Is leasehold a bad option if the foreign quota is full?

Leasehold is a legitimate registered right for 30 years, but it is economically different from freehold: renewal beyond 30 years is a contractual promise, not a guaranteed right, and resale values decline as the term runs down. Price a leasehold unit accordingly — or prefer freehold in another building.

Is a "30+30" lease really 60 years?

No. Section 540 of the Civil and Commercial Code caps a registered lease at 30 years, so only the first 30 years exist as a registered property right. The second 30 is a contractual option to renew. It is worth something, but it is not the same thing, and it should not be priced as though it were.

If the building is sold, does my lease renewal option survive?

The lease does; the renewal option generally does not. Section 569 keeps a registered lease alive when the property changes hands, so a buyer of the freehold takes it subject to your lease. But the option to renew is a personal right against the party who granted it, and a successor in title is not bound by it. If the grantor sells up or dissolves, you are left with a contractual claim rather than a right to remain.

Can I get a 99-year lease through a Thai company that owns the property?

The 30-year cap applies to that lease too, so the "99 years" is still renewal promises stacked on a 30-year registration. The structure also introduces a separate risk: if the company's Thai shareholders are nominees holding on a foreigner's behalf, that is prohibited, with forced disposal of the land and criminal exposure for the nominees among the consequences under the Land Code. Take proper Thai legal advice before relying on it.
