Thailand does not have rent control legislation imposing caps on rent increases, unlike some jurisdictions. However, there are important restrictions that landlords must observe.
Rent Increase Process in national
Check Applicable Rules
Confirm the increase complies with frequency and notice requirements under Civil and Commercial Code (CCC) Sections 537–574 + Hire of Property Act.
Prepare Written Notice
Draft a formal written notice with the new amount and effective date.
Serve the Required Period
Deliver the notice at least 30–60 Days Written Notice before the new rent begins.
Allow Tenant to Respond
The tenant may contest the increase through Civil Court / Consumer Disputes Court within the prescribed window.
Regulatory Overview
Mid-Lease Increase Prohibitions
Business Landlords (3+ Units)
Under the OCPB Notification, business landlords may not:
- Increase rent unilaterally before the lease term expires
- Add service charges or common area fees without prior notice
- Include contract clauses granting discretionary rent adjustments
- Charge utility rates above government-prescribed rates
Private Landlords
Private landlords may adjust rent per their contract terms, but cannot increase rent unilaterally if the lease does not provide for such adjustments.
Rent Adjustments at Renewal
When a lease expires, landlords may:
- Propose a new rent rate for the next lease term
- Negotiate with the tenant on an appropriate rate
- Decline to renew if terms cannot be agreed upon
There are no legal limits on the amount of rent increase at renewal.
Unfair Contract Clauses
The following clauses are considered unfair and may be voided by the courts:
- Clauses allowing the landlord to increase rent at any time without consent
- Clauses tying rent to an automatic index without a cap
- Clauses requiring the tenant to accept additional charges not specified in the original agreement
Best Practices for Landlords
- Set rent at market rates — Research comparable rental rates in your area
- Provide advance notice — Notify tenants 1–2 months before renewal with proposed changes
- Include renewal terms in the lease — Reserve the right to adjust rent at renewal
- Increase rent reasonably — Excessive increases may drive away good tenants
- Document everything in writing — All rent changes should be formalized
