Under the Thai Civil and Commercial Code (Book III effective 1 January 1929), commercial security deposits in Thailand have no statutory cap (CCC Section 537), unlike residential deposits governed by the OCPB. For specific high-value or long-term leases, the Act on Lease of Immovable Property for Commercial and Industrial Purposes B.E. 2542 (1999) may also apply. Terms are freely negotiated between landlord and tenant.
Commercial Bond Process in national
Negotiate Bond
Agree on bond type and amount during commercial lease negotiations.
Collect Security
Receive bank guarantee or cash bond before tenant takes possession.
Hold During Tenancy
Keep the bond securely for the full commercial tenancy duration.
Release or Claim
Return bond at lease end if no outstanding obligations, or make claims for documented breaches.
Deposit Limits
Market Practice
- Office, retail, and warehouses typically require 1–3 months' rent according to standard market practice.
- Registration Requirements: Under CCC Section 538, any lease exceeding three years must be made in writing and registered with the competent Land Office to be fully enforceable for the entire term.
Allowable Deductions
Landlords may deduct from the deposit for:
- Damages caused by the tenant's fault (CCC Section 562)
- Unpaid rent
- Unpaid utilities and service charges
- Costs of removing tenant fit-outs or modifications (if specified in the lease)
Note: Landlords are generally prohibited from deducting for normal wear and tear (CCC Section 563) unless expressly permitted by the lease agreement.
Return Timeline
No specific statute governs the return timeline for commercial deposits — it must be specified in the lease. If the contract is silent, the deposit must be returned upon the expiration of the lease and the fulfillment of all tenant obligations (CCC Section 564). Standard market practice is 30–60 days after lease termination.
Best Practices for Landlords
- Define deposit terms clearly in the lease — Amount, return conditions, timeline
- Prepare a property condition report before and after occupancy
- Specify a deposit return deadline in the contract
- Keep all receipts for repairs and deductions
