Thailand Landlord-Tenant Laws: Complete Guide for Property Owners

Thailand's rental property legislation is anchored by the Civil and Commercial Code (CCC) and the strict OCPB Notifications for professional landlords. As of 2026, compliance for foreign owners has become a primary focus of government enforcement.

1. Landlord Categories (OCPB)

Thai law differentiates between private and business landlords.

• Business Landlords (3+ Units): Must comply with the OCPB Notification B.E. 2568 (2025). Contracts must be in Thai, security deposits are capped at 1 month, and advance rent is capped at 1 month.
• Private Landlords: Governed primarily by the CCC. Market norms typically allow for 2 months' deposit.

2. Security Deposits and Utilities

Under the current OCPB regulations:

• Cap: Maximum 1 month's rent as a security deposit for business landlords.* Return: Must be returned within 7 days (no damage) or 14 days (after inspection).
• Utilities: Business landlords cannot charge more than the official government utility rates (PEA/MEA for electricity, MWA/PWA for water).

3. Eviction Procedures

Self-help evictions (cutting utilities, changing locks) are illegal and can lead to criminal charges (Trespass).

1. Demand Notice: Issue written notice giving at least 15 days to pay or remedy.
2. Termination: Formally terminate the lease if the tenant fails to comply.
3. Court Case: File a lawsuit to obtain a court order for eviction.

4. Foreign Ownership and the 2026 Crackdown

Foreigners can own up to 49% of the total floor area in a condominium building.

• Nominee Warning: Using Thai "nominees" to hold property in the 51% Thai quota is being heavily penalized in 2026.
• Freehold Registration: Requires proof that funds were brought into Thailand in foreign currency (FETF).

5. Maintenance Obligations

Landlords are responsible for structural repairs and ensuring the property is habitable. Tenants handle "minor repairs" (lightbulbs, etc.) and ordinary maintenance. For properties managed by businesses, a Property Condition Report with photos is mandatory at handover.
