The Definition
The Condominium Act B.E. 2522 (1979), as amended, is Thailand's primary legislation regulating the establishment, ownership, management, and operation of condominium buildings, requiring projects to be registered with the Land Department. It uniquely allows foreigners to own condominium units on a freehold basis, capped at 49% of the total sellable floor area per building, while mandating Thai ownership for the remaining 51%. The Act also governs juristic persons for common area management and sets rules for unit transfers, fees, and dispute resolution.
Western buyers might expect unrestricted freehold condo ownership similar to the US or Europe, but Thailand caps foreigners at 49% of a building's floor area to prioritize Thai control, preventing full foreign dominance in any project. Unlike many Western systems with strata titles allowing flexible foreign ownership, Thai condos require pre-verified quota availability via juristic person letters, and funds must be remitted as foreign currency for title registration. Liability for common areas falls under a mandatory juristic person, differing from some Western HOAs by enforcing strict Thai-majority ownership thresholds.
Buyers unaware of the 49% quota may deposit on a unit only to find it unavailable at transfer, losing time and potentially deposits without recourse if not verified upfront. Foreigners face added hurdles proving foreign remittance, delaying titles if banks issue incorrect FET forms or quotas fill mid-process. Unregistered apartment buildings falsely marketed as condos fall outside Act protections, exposing owners to eviction or management disputes without juristic oversight.
Foreigners can own freehold condo units only within the 49% quota, requiring proof of foreign currency remittance (FET form) and juristic confirmation of quota availability, unlike Thai citizens who face no quota limits and qualify for reduced transfer fees (0.01% until June 30, 2026, up to THB 7 million). Thai citizens can own unlimited units across projects without remittance proof, while foreigners risk leasehold only if quotas are full. No nationality-based visa restrictions apply to foreigners, but banks rarely lend to non-residents without Thai spouses.
The Act is administered by the Department of Lands (Land Department) for registration under Section 6 and ownership transfers, with Section 19 specifically governing the 49% foreign quota based on aggregate unit floor space. Amendments, including those in 1991, expanded foreign eligibility, while the Land Code and Foreign Business Act prohibit nominee structures or company workarounds for exceeding quotas. The Office of the Consumer Protection Board (OCPB) overlays rules for off-plan sales, standardizing contracts since January 2025.
Let’s look at a real-world scenario to understand how Condominium Act is applied during a property transaction.
Freehold title transfers successfully; she pays standard 2% transfer fee (THB 80,000), securing perpetual ownership compliant with Section 19.
The Situation: A Canadian buyer paid a THB 400,000 deposit on a Phuket beachfront condo unit in 2025.
The Challenge: At transfer, the juristic letter revealed the 49% quota was exceeded due to unreported prior sales, forcing leasehold instead of promised freehold, with no refund as the sales contract lacked quota contingency.
The REMAX Difference:
A REMAX agent pre-verifies quota via official juristic documents and Land Department records before any deposit, includes escrow clauses tying funds release to quota confirmation, and coordinates FET banking upfront to ensure seamless freehold transfer.
A quick breakdown of how this term compares to its closest alternative.
| Feature | Condominium Act | Leasehold |
|---|---|---|
| Ownership Term | Perpetual freehold ownership for foreigners (within 49% quota) | Fixed 30-year terms (renewable but non-guaranteed) |
| Management Structure | Mandates juristic management for stability | Private landlord control, risking non-renewal |
| Applicability | Applies only to Act-registered condos | No quota but weaker title transferability |
Ignoring the Condominium Act risks buying into unregistered projects without legal protections or hitting the 49% quota wall, turning a dream investment into a leasehold downgrade or total loss. Mastery ensures secure freehold titles, maximizing resale value and peace of mind in Thailand's foreigner-restricted market.
Always demand the juristic person's dated quota letter before signing any reservation—pair it with a Land Department search to confirm registration under Section 6, avoiding 90% of quota disasters.
Reality: Only up to 49% of total floor area; 100% was a temporary 1999-2004 measure in select areas, now expired.
Reality: Section 19 mandates juristic quota confirmation and FET for title registration; verbal assurances are invalid.
