Thai Condominium Act Explained for Foreign Buyers 2026

The Condominium Act B.E. 2522 (1979) — with amendments — is the foundation of Thailand’s condominium regime. For foreign buyers, it answers the most important question: Can I own this unit freehold, and what rights come with it?

This guide explains the foreign ownership cap, juristic person governance, common property, maintenance fees, and what the Act does not regulate.

What the Condominium Act establishes

The Act creates a legal framework for:

• Registering a condominium as a juristic person — a legal entity representing co-owners.
• Dividing ownership into private units and common property (lobbies, pools, corridors).
• Setting rules for management, fees, and governance.

Foreign ownership provisions are embedded in this framework.

Foreign ownership limit (49% rule)

Foreigners may acquire condominium units freehold only within the quota: foreign ownership cannot exceed 49% of the total sellable floor area of the condominium.

Practical implication: Each building has a finite foreign capacity — verify before deposit.

Freehold title rights for qualifying foreigners

When you register within quota, you receive Chanote title to your unit — a strong, defensible ownership record.

Juristic person structure

The condominium’s juristic person is governed by:

• Regulations registered with authorities.
• Annual general meetings where owners vote on budgets and major projects.

Voting is typically tied to ownership ratio — larger units carry more voting weight.

Common property rights

You own your private unit and share common property proportionally. You cannot remodel structural elements or common corridors without compliance with regulations and juristic approval.

Maintenance fees and sinking fund

Owners must contribute to:

• Monthly common area fees — CAM fees.
• Sinking fund for capital repairs — roof, elevators, major systems.

These obligations survive personal preferences — non-payment can lead to enforcement actions.

Renovation and subletting

The Act and juristic regulations govern internal renovations — often requiring notification or approval for structural or system changes.

Subletting: Condos are generally sublettable unless regulations restrict — short-term rental rules may also involve local regulations beyond the Act.

What the Act does not fully cover

Short-term rental licensing and local tourism rules evolve separately from the Condominium Act. Owners must follow:

• Juristic house rules.
• Provincial and local requirements where applicable.

Always ask your lawyer and property manager for current guidance — not forum posts.

Recent amendments and future changes

Law evolves — 2026 buyers should confirm current foreign quota rules and registration procedures with counsel. Do not rely on outdated articles.

Frequently Asked Questions

Does the Condominium Act protect foreign owners equally? +

Once registered within foreign quota, foreign owners hold title and governance rights in the juristic person like other co-owners — subject to the same fees and rules. The Act is not 'anti-foreign' — quota is the gate.

Can the juristic person block my rental? +

If registered regulations restrict certain rental types, enforcement may be possible. Many disputes are fact-specific. Review regulations and local rules before buying for Airbnb-style use.

What happens if foreign quota is exceeded? +

The Land Department should not register new foreign acquisitions beyond quota. This is why pre-purchase verification matters — do not assume marketing claims.

Is the Condominium Act the only law I need? +

No — tax law, contract law, consumer protection, and local ordinances also apply. The Act is the core of condominium ownership, not the entire legal universe.

Do amendments change foreign ownership percentages? +

Rules can change — always verify current law with a Thai property lawyer at purchase time. This article is informational, not legal advice.
