How do you compare commercial lease types in Thailand?
A Thailand commercial lease cannot be compared on its label or its quoted rent alone. Build a written all-in schedule covering rent, service charges, utilities, taxes, insurance, repairs, deposits, fit-out, escalation and exit costs, then reconcile that schedule against the signed lease and any Land Office registration required.

Do not select a Thai commercial lease from the label or quoted rent alone. Build a written all-in schedule for rent, service charges, utilities, taxes, insurance, repairs, deposits, fit-out, escalation and exit costs, then reconcile that schedule to the signed lease and any Land Office registration required.

What does a gross lease mean?
A gross structure generally bundles more property-level operating costs into the rent. The contract should still identify what remains outside the quoted amount.
- utilities and telecommunications;
- interior maintenance and fit-out;
- parking, signage and access charges;
- tax treatment and invoicing;
- extra services and after-hours use.
What is a modified-gross lease?
A modified-gross structure splits costs. A common example is base rent plus a separately stated building service or common-area charge, but the allocation must be read from the contract.
- define each recoverable cost;
- state the allocation method;
- require supporting records and reconciliation;
- set notice and adjustment rules;
- address vacancies, capital work and management fees.
What is a net or triple-net lease?
A net structure passes specified property costs to the tenant in addition to base rent. “Triple net” is commonly used to describe tax, insurance and maintenance pass-throughs, but the phrase does not replace the actual drafting.
- identify the exact taxes and insurance;
- separate routine maintenance from structural work;
- define capital expenditure treatment;
- set audit and dispute rights;
- cap or exclude costs the tenant did not approve.
How does a percentage lease work?
A percentage lease adds a sales-based payment to base rent or another minimum charge. The reporting clause is as important as the rate.
- define gross sales and exclusions;
- state the breakpoint and calculation period;
- address refunds, online sales and related entities;
- set reporting and audit rights;
- protect confidential business information.
Which costs belong in an all-in comparison?
- base rent and escalation;
- service or common-area charges — note that under Revenue Code s.81(1), item 19, the rent for immovable property itself is exempt from VAT, but confirm separately how service charges and other add-ons are taxed;
- utilities, metering and deposits;
- taxes, insurance and licence costs;
- fit-out, reinstatement and repair;
- parking, signage and operating-hour charges;
- renewal, termination and holdover costs.
What should be verified before signing?
- Confirm the landlord and authority to lease. A Thai corporate landlord’s registration certificate can be checked against the Department of Business Development register.
- Match the premises, plans, parking and access rights.
- Confirm permitted use, licences and building restrictions.
- Reconcile the commercial offer to the final lease.
- Review registration, tax and document requirements. Under the Civil and Commercial Code, s.538, a lease over three years must itself be registered to be enforceable for its full stated term — an unregistered long lease reverts to a three-year lease regardless of what the contract says. Confirm registration with the Department of Lands, and price the stamp duty from the Revenue Department’s Stamp Duty Schedule, item 1 of which charges 1 baht per 1,000 baht (or fraction) of the rent and key money for the whole lease term on a hire of land, building, other construction or floating house, and treats an unstated term as three years.
- Record handover, fit-out and opening conditions.
Before you act on this checklist: BAANLYY and BAANLYY LLC are not attorneys and do not give legal advice. Whether a lease binds, registers or is taxed the way you expect turns on the signed Thai-language documents and on current Land Office and Revenue Department practice. Have a qualified Thai lawyer review the lease and its schedules before you sign.
Use the commercial due-diligence checklist before treating a negotiated term sheet as a complete property review.

Are gross, net and triple-net lease labels legally standardized in Thailand?
Do not rely on the label alone. The signed Thai and English lease documents, schedules and registered rights control the parties' obligations.
What is the safest way to compare two commercial lease offers?
Build an all-in occupancy-cost schedule showing base rent, service charges, utilities, taxes, insurance, repairs, fit-out, deposits, escalation and end-of-term costs.
Can a service charge change during the lease?
It can if the contract permits adjustment. Confirm the calculation, supporting records, notice, cap and reconciliation process before signing.
Does a percentage lease require sales reporting?
Usually yes. The lease should define gross sales, exclusions, reporting frequency, audit rights, systems access and confidentiality.
Should a long commercial lease be registered?
Under the Civil and Commercial Code, s.538, a lease of immovable property for more than three years (or for the life of the lessor or the lessee) must be made in writing and registered with the competent official — an unregistered long lease can only be enforced for three years, whatever term the contract states. Registration takes place at the Land Office and carries its own fee and stamp duty. Confirm the current process and any structure-specific exceptions with qualified Thai counsel before relying on a long occupancy period.
