Thailand Condo Foreign Quota Calculation: How the 49% Rule Really Works

8/5/2026

Thailand's foreign condo quota is measured in square metres of floor area, not units — a distinction that trips up more buyers than any other rule in the market. Here's the maths, the stalled 75% reform, and what it means for Pattaya buyers.

Thailand's condo foreign quota calculation is based on saleable floor area, not the number of units. Under Section 19 of the Condominium Act, foreigners may collectively hold freehold title to no more than 49% of a registered project's total sellable floor space, with the remaining 51% reserved for Thai ownership. Get this wrong and a signed reservation can stall at the Land Office. Here's how the sums actually work, why a proposed reform hasn't changed anything yet, and what it means if you're buying in Pattaya.

How the Thailand Condo Foreign Quota Calculation Actually Works

The rule sounds simple but the mechanics catch people out. <cite index="2-1">The Condominium Act B.E. 2522 (1979), Section 19, caps the aggregate floor area of saleable condominium units that may be foreign-owned at 49% of the total saleable floor area of the registered condominium project.</cite>

A few details matter more than most marketing brochures let on:

• It's measured in square metres, not units. A studio and a penthouse count toward the quota in proportion to their floor area, not as one unit each.
• The quota is per building, not per developer or per project phase. A neighbouring tower in the same development can have entirely different quota availability.
• Common areas are excluded from the calculation — only saleable unit floor space counts.
• Compliance is checked at registration, meaning the moment title transfers at the Land Office, not when a reservation contract is signed.

A Worked Example

Take a project with 10,000 sq.m. of total saleable area. <cite index="6-0">Foreigners can own up to 4,900 sq.m. (49%), while Thais must own at least 5,100 sq.m. (51%). Once the 49% foreign quota is reached, no more units can be sold freehold to foreign buyers.</cite>

If a project has already sold 4,500 sq.m. to foreign owners, that leaves exactly 400 sq.m. of headroom — enough for a small studio, but not a two-bedroom unit, however much a sales agent insists otherwise.

Why the 75% Quota Proposal Hasn't Changed the Math (Yet)

Buyers regularly ask whether the quota is about to rise to 75%. It's a fair question — the idea has circulated in Thai policy circles for two years. <cite index="3-0">A proposal to raise the foreign condominium quota to 75% in designated special economic zones is under discussion, but no official bill has been tabled as of 2026.</cite>

Early versions of the proposal were geographically targeted rather than nationwide. <cite index="2-0">Pilot zones were floated rather than a blanket nationwide increase, with proposals leaning toward geography-specific quota adjustments — for example a 75% foreign quota in Phuket condos while Bangkok remained unchanged at 49%.</cite> Pattaya was mentioned among the candidate resort areas alongside Phuket and Samui.

As of the most recent tracking, the reform remains stalled. <cite index="5-0">The proposal to lift the foreign ownership cap in condominiums from 49% to 75% of saleable area has not been implemented and the 49% limit remains in force.</cite> Sensible underwriting means treating the current 49% ceiling as the baseline and any change as upside, not something to bank a purchase decision on.

What Happens When a Building's Quota Is Full

Once a project hits 49%, the Land Office will not register another freehold foreign transfer in that building, regardless of what a reservation agreement promised. <cite index="4-0">If an error is discovered after the fact, the unit must be transferred to a Thai national or converted to leasehold within one year, as specified in Article 19/12 of the Condominium Act.</cite>

This is why due diligence on quota status before paying a deposit matters more than almost any other check in a Thai condo purchase. <cite index="5-2">A Thai quota unit is not the same as foreign freehold, and buyers should ask the condominium juristic person, seller and lawyer for written confirmation, verified through the transfer process before paying a meaningful deposit.</cite>

Leasehold vs Freehold: The Fallback When Quota Runs Out

When a building's foreign quota is exhausted, buyers still have options. <cite index="9-0">A registered lease does not count toward the foreign quota, so buyers can purchase on a leasehold basis or wait for foreign-quota space to open, with some developers maintaining waiting lists.</cite>

Structuring a purchase through a Thai company to dodge the quota is a well-known red flag rather than a shortcut. <cite index="9-1">Such an arrangement is distinct from the legitimate 49% quota calculation — a Thai-majority company may legally count on the Thai side, but a company or staff arrangement set up specifically to conceal foreign control does not.</cite>

Financing Adds Another Layer to the Decision

Quota availability isn't the only number that shapes what a buyer can realistically purchase. Mortgage terms have also shifted over the past year. <cite index="11-0">Thai mortgage rates for foreign buyers were running in the region of 3.5% to 6% APR through banks such as SCB, Kasikorn and Bangkok Bank in 2025.</cite> Separately, <cite index="10-0">general Thai mortgage rates were sitting around 6.5–7% as of August 2025, with the exact figure trackable on the Bank of Thailand's own rate publications.</cite>

Most foreign buyers still rely on cash or overseas financing rather than a Thai mortgage, since local lending to non-residents remains limited and conditional. That makes quota math — how much freehold floor space is actually available in a given building — the more decisive constraint for most international buyers than the loan market.

Where This Matters Most: Pattaya and the Eastern Seaboard

Quota pressure is not evenly distributed across Thailand. Popular beachfront stretches in Pattaya, Jomtien and Na Jomtien tend to fill their foreign allocation faster than inland or lower-demand buildings, simply because that's where international demand concentrates.

Buyers hunting specifically along the beachfront corridor should check our breakdown of Jomtien beachfront condo prices for how location premiums interact with quota scarcity, and our per-square-metre data in Pattaya condo prices per square metre for how pricing has moved. If you're weighing whether now is the moment to commit, our analysis of Thailand's condo transfer volume decline is worth reading alongside quota data, since slower transfers in some segments can mean more available foreign-quota inventory than the headlines suggest.

How to Verify Quota Before You Buy

A short checklist protects buyers from the most common quota mistake — assuming availability rather than confirming it in writing.

1. Request the building's current foreign-quota usage percentage from the juristic person in writing.
2. Confirm the figure is based on floor area, not unit count.
3. Re-verify quota status shortly before the transfer date, since it can change between reservation and registration.
4. If the quota is full, ask explicitly whether the unit is offered on leasehold, and understand what that means for resale.
5. Avoid any structure marketed as a way to "get around" the 49% limit — these carry real legal risk.

The 49% rule isn't going away soon, and no bill has changed it despite years of discussion. Buyers who treat the quota calculation as a hard constraint — and verify it independently — avoid the deals that later unravel at the Land Office.
