Governed by the Civil and Commercial Code (effective 1 April 1925) and the Notification of the Contract Committee Re: The Business of Residential Property Rental as a Contract-Controlled Business B.E. 2562 (2019), Thailand does not have rent control legislation imposing caps on rent increases. However, there are specific restrictions that landlords must observe depending on their scale of operation.
Rent Increase Process in national
Check Applicable Rules
Confirm the increase complies with the lease agreement and, if renting 5 or more units, OCPB regulations.
Prepare Written Notice
Draft a formal written notice with the new amount and effective date.
Serve the Required Period
Deliver the notice in advance as stipulated in the lease agreement before the new rent begins.
Allow Tenant to Respond

Regulatory Overview
Mid-Lease Increase Prohibitions
Business Landlords (5+ Units)
Under the OCPB Notification B.E. 2562, business landlords (defined as those renting 5 or more units to individual tenants for residential purposes, excluding dormitories and hotels) 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.
Common Misconceptions in national
Don't fall for these common myths. Know what the law actually says.
"A landlord in Thailand can increase rent verbally at any time."
Rent increases must be mutually agreed upon and formalised according to the lease agreement. The Civil and Commercial Code does not grant landlords a statutory right to unilaterally increase rent with 30-60 days notice.
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
Frequently Asked Questions: National Rent Increases FAQ
Thailand does not impose statutory percentage caps. Rent is governed by the lease agreement and CCC Sections 537–571. For business operators (5+ units), the OCPB prohibits unilateral increases during the term.
Tenants may apply to the Office of the Consumer Protection Board (OCPB) or the Consumer Case Division of the Court to challenge unfair contract terms or if the landlord violates OCPB regulations regarding mid-lease increases.
