Thailand's security deposit laws were significantly strengthened by the OCPB Contract Committee Notification B.E. 2568, which took effect on September 4, 2025. This guide covers every aspect of the updated regulations that landlords must follow.
Security Deposit Process in national
Collect Deposit
Collect the security deposit (up to 1–3 Months’ Rent) before the tenant takes possession.
Document Condition
Create a move-in condition report signed by both landlord and tenant.
Hold During Tenancy
Keep the deposit in a designated or legally required account.
Return or Claim
Return within 30 Days After Tenancy End after tenancy end, with written justification for any deductions.
Security Deposit Limits
Business Landlords (3+ Units)
Under the OCPB Notification B.E. 2568, business landlords face the following limits:
For annual payment leases, the combined deposit and advance rent must not exceed 1 year's rent.
Private Landlords (Fewer than 3 Units)
There is no statutory cap on security deposits for private landlords. 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
- Cleaning costs — only if the unit condition is below the move-in standard
- Tenant-caused damage — beyond normal wear and tear
- 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
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 may face:
- Fines of up to THB 200,000 (approximately USD 5,700)
- Imprisonment of up to 1 year, or both
- Civil lawsuits 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
