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 Notification of the Contract Committee Re: The Stipulation of Residential Property Leasing as a Contract-Controlled Business B.E. 2568 (2025), which became effective on September 4, 2025. Compliance for foreign owners remains a primary focus of government enforcement.

1. Landlord Categories (OCPB)

Thai law differentiates between private and business landlords.

• Business Landlords (3+ Units): Under the B.E. 2568 (2025) Notification, any person or entity leasing 3 or more residential units is classified as a 'Business Operator'. Contracts must be in Thai, and for monthly leases, the combined total of security deposits and advance rent is capped at 3 months' rent.
• Private Landlords: Governed primarily by the CCC. Market norms typically allow for 2 months' deposit.

2. Security Deposits and Utilities

Under the OCPB Notification B.E. 2568:

• Cap: For short-term/monthly leases, business landlords are prohibited from collecting a combined total of security deposits and advance rent exceeding 3 months' rent. For long-term leases (exceeding 3 years) with annual payments, the combined total cannot exceed 1 year's rent.
• Return: The deposit must be returned immediately if no damage is found, or within 7 days if an inspection is required. If damage is found, the landlord must return the remaining balance within 14 days after deducting verified repair costs, providing a detailed statement of deductions.
• 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 under Penal Code Sections 309 and 362.

1. Demand Notice: Business Landlords must provide at least 30 days' written notice for material breaches. For private landlords under the CCC, if rent is payable monthly, at least 15 days' notice to pay is required before termination.
2. Termination: Formally terminate the lease if the tenant fails to comply. For urgent misconduct affecting other residents, business landlords may issue a 7-day notice.
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.
