Thailand's security deposit laws are primarily governed by the Civil and Commercial Code (effective 1 April 1925) and the OCPB Contract Committee Notification B.E. 2568 (effective 4 September 2025). These regulations significantly strengthened tenant protections and established strict caps for business landlords.
Security Deposit Process in national
Collect Deposit
Collect the security deposit (max 1 month for business) before the tenant takes possession.
Document Condition
Create a move-in condition report signed by both landlord and tenant.
Manage Funds
Keep the deposit available for immediate return upon lease termination.
Return or Claim
Return immediately or within 7-14 days, with written justification for any deductions.
Security Deposit Limits
Business Landlords (3+ Units)
Under the OCPB Notification B.E. 2568, business landlords (those renting three or more units) face the following limits:
Private Landlords (1–2 Units)
There is no statutory cap on security deposits for private landlords under the Civil and Commercial Code. Market practice is typically 2–3 months' rent. Deposit terms should be clearly documented in the lease agreement.
Allowable Deductions
Landlords may deduct from the security deposit for:
- Unpaid rent — including any rent owed through the end of the tenancy (CCC Section 560)
- Cleaning costs — only if the unit condition is below the move-in standard
- Tenant-caused damage — beyond normal wear and tear (CCC Section 562)
- Unpaid utilities — outstanding electricity and water bills
What Cannot Be Deducted
- Normal wear and tear — faded paint, worn flooring, minor scuffs
- Pre-existing damage — conditions documented before move-in
- Unnecessary cleaning — the unit must be returned to move-in condition, not better
- Inflated repair costs — charges must reflect actual expenses
Return Deadlines
Common Misconceptions in national
Don't fall for these common myths. Know what the law actually says.
"A landlord in Thailand can keep the deposit for any minor issue after move-out."
Security deposit deductions must relate to documented damage beyond normal wear and tear, rent arrears, or lease breaches. All deductions require written justification under OCPB B.E. 2568.
Move-In Inspection Report
Under the OCPB Notification B.E. 2568, business landlords must prepare a move-in condition report:
- Must include dated photographs of each room and area
- Must be jointly signed by landlord and tenant
- Must be attached to the lease agreement as an appendix
- Serves as the baseline for evaluating deposit deductions at move-out
Penalties for Non-Compliance
Business landlords who fail to comply with security deposit regulations under the Consumer Protection Act may face:
- Fines of up to THB 200,000
- Imprisonment of up to 1 year, or both
- Civil lawsuits in the Consumer Case Court by tenants seeking damages
Best Practices for Landlords
- Document everything at move-in — Take dated photos and videos of the unit's condition
- Use a move-in/move-out checklist — Have the tenant sign it
- Keep deposits in a separate account — Not legally required but best practice
- Return deposits promptly — Don't wait until the deadline
- Keep all receipts — For any deductions you claim
- Specify deposit terms clearly in the lease — Especially conditions for deductions
Frequently Asked Questions: National Security Deposits FAQ
For business landlords (3+ units), no. Amounts above the 1-month limit in OCPB B.E. 2568 are unenforceable. Private landlords (1-2 units) are governed by the Civil and Commercial Code and may negotiate higher deposits.
Tenants may file a complaint with the OCPB or initiate a lawsuit in the Consumer Case Court. Business landlords face significant criminal penalties for non-compliance with return deadlines.
