Commercial rent increases in Thailand enjoy significant flexibility since there is no rent control legislation for commercial properties. Contract terms are the primary governing mechanism.

Rent Review

Per Lease Terms

Common Structure

Annual CPI Adjustment

Commercial Rent Review Process in national

Review Rent Clause

Check the specific rent review method in the commercial lease.

Calculate New Amount

Apply the agreed formula to calculate the adjusted rent.

Serve Written Notice

Provide written notice per the lease’s required notice period.

Commission Valuation if Needed

Obtain an independent market rent valuation for market review clauses.

Common Rent Escalation Mechanisms

Mechanism	Description
Fixed percentage	Increases by X% every Y years
CPI-linked	Tied to the Consumer Price Index
Market rate reset	Revalued at market rates upon renewal
Stepped rent	Predetermined rent for each period
Percentage rent	Base rent plus percentage of sales revenue (retail/malls)

Legal Principles

No caps on commercial rent increases
Must be specified in the lease — Escalation mechanisms should be clearly defined
No unilateral increases unless the contract grants such rights
Good faith principle — Courts may review whether increases are unconscionable

Rent Negotiation at Renewal

When a lease expires, both parties are free to negotiate new rent terms without legal restrictions. Either party may choose not to renew if terms are unsatisfactory.

Best Practices for Landlords

Define escalation mechanisms in advance in the lease
Use CPI as a benchmark for fair adjustments
Provide advance notice before contractual rent adjustments
Research market rates before negotiating renewals
