Rights and Obligations of Residential Tenants and Landlords Under Thai Law

Before getting into the details of legal rights and duties, we should start by understanding the basics of rental law first, because this is the key framework that defines the relationship between tenants and landlords. Whether it is a detached house, a townhome, or a condominium, all are governed by the same legal principles.

Laws related to residential rentals in Thailand

At present, residential leasing is governed by the Civil and Commercial Code, Sections 537–571, which set out the general principles of lease agreements. A lease is defined as a contract granting temporary use of property, for which the tenant must pay rent as consideration. 

In addition, there is the Notification of the Contract Committee (No. 26), which has been in effect since 2018, to protect consumers in cases of monthly residential rentals, such as apartments or rental rooms with 5 or more units for rent, whether in the same building or across multiple buildings. This also includes houses and condominiums. This law sets out key requirements, such as:

• The owner/lessor is prohibited from changing the contract without giving the tenant prior notice.

• The security deposit must be refunded within 7 days after the contract ends.

• Water and electricity disconnection, or eviction of the tenant, is prohibited without a court order.

In other words, rental law in Thailand aims to create a balance between both parties and reduce inequalities that may arise in practice.

What is a residential lease agreement, and what elements should it include?

A residential lease agreement is an arrangement between a tenant and a homeowner/landlord for the use of property, with rent as consideration. This agreement may be made in writing or verbally; however, in practice, having a written lease helps prevent issues more effectively because it provides clear evidence if a dispute arises.

Key elements that should be included in the agreement are:

1. Parties’ information: names, addresses, and contact details of both parties

2. Property details: clearly specify the house or rental unit, such as location, area, and unit/room number

3. Lease term: specify the start and end dates of the lease

4. Rent and payment method: amount, due date, and payment account details

5. Security deposit and refund conditions

6. Responsibilities for property care: who is responsible for repairs or utilities

7. Termination conditions: notice requirements, timeframe, and permissible grounds for termination

A clear, well-drafted agreement helps reduce misunderstandings and serves as legal evidence if a dispute arises in the future. It also helps both tenants and homeowners/landlords comply with the law correctly and fairly.

Under Thailand’s residential rental laws, tenants have clearly protected rights to ensure safe and fair living conditions—especially under the Civil and Commercial Code, Sections 537–571, and the Notification of the Contract Committee on Residential Lease Agreements, B.E. 2561 (2018), which is regarded as a key residential lease law.

Whether a tenant is an individual renting a single house or renting a condo in a large development, these legal rights apply equally in all cases, and the homeowner or landlord must strictly respect them.

1. The right to reside in and use the property as agreed in the contract

A tenant’s first legal right is the right to reside in and use the property as specified in the lease agreement. The landlord or homeowner has no right to enter the tenant’s premises without permission—whether to inspect, carry out repairs, or remove personal belongings.

Under Section 546 of the Civil and Commercial Code, the landlord must refrain from any act that interferes with the tenant’s right of possession. Therefore, if the homeowner enters the premises arbitrarily, it constitutes a direct violation of the tenant’s rights.

2. The right to maintenance and repairs

Under Section 548, the landlord has a duty to keep the property in a usable condition throughout the lease term. If damage occurs that was not caused by the tenant—such as a leaking pipe, electrical faults, or a leaking roof—the landlord must arrange repairs promptly and must not shift the burden to the tenant.

In addition, if the damage prevents the tenant from living normally—for example, flooding or severe damage to the room—the tenant has the right to request a rent reduction or terminate the residential lease in accordance with the law.

3. The right to fairness regarding the security deposit

One of the most common disputes between tenants and homeowners concerns the security deposit. The law sets out clear principles in the Notification of the Contract Committee on Residential Lease Agreements, B.E. 2561 (2018), stating that:

The landlord must return the security deposit to the tenant within 7 business days after the tenant moves out and the property inspection has been completed.

If the landlord deducts the deposit without reasonable grounds, or fails to return it within the prescribed timeframe, the tenant may file a complaint with the Office of the Consumer Protection Board (OCPB) to seek a fair resolution.

4. The right to fair termination of the lease

A tenant has the right to terminate the lease if the landlord breaches key terms—for example, failing to repair damage to the property to the extent that it is no longer habitable, or repeatedly interfering with the tenant’s rights, such as cutting off water or electricity without justification.

In cases where the lease is with a residential rental business operator (commercial leasing), the law provides that the tenant may terminate the agreement without penalty after having occupied the premises for more than 30 days, provided that at least 30 days’ prior notice is given. This is direct consumer protection under the residential lease law

In summary, tenants’ rights are not only meant to protect tenants; they also provide a framework that helps homeowners better understand the scope of their own obligations. When both parties respect the rights under Thailand’s residential rental laws, it helps reduce conflicts and makes residential renting as smooth and fair as possible.

Although tenants’ rights are clearly protected under the housing lease law, on the other hand, tenants also have legal duties that must be complied with to ensure the lease is carried out properly and fairly toward the homeowner or landlord.

In general, tenants’ duties are set out in the Civil and Commercial Code, Sections 549–571, and in some cases may be supplemented under the Residential Lease Contract Act B.E. 2561 (2018) for residential tenants leasing from commercial lessors, such as apartment or condominium owners who rent out multiple units.

1. Duty to pay rent on time

One of the key duties tenants must comply with is paying rent by the due date, which is an essential condition of the contract. If a tenant defaults by failing to pay rent as agreed, the landlord has the right to terminate the contract and claim damages under Section 560 of the Civil and Commercial Code.

In addition, where the Residential Lease Contract Act applies—for example, where the lessor has multiple units—the lessor must issue a rent receipt every time the tenant makes payment to ensure transparency and prevent disputes later on.

Expert tip: Tenants should always keep proof of rent payment, such as bank transfer slips or receipts, as these are important documents for substantiating tenants’ rights in the future.

2. Duty to maintain the property in good condition

Tenants must use the property for the purpose for which it was rented and keep it in good condition, and must not cause damage through negligence or intent, under Section 552 of the Civil and Commercial Code. If damage occurs from improper use—such as drilling into walls without permission or keeping pets in a unit where pets are prohibited—the tenant may be liable for the full amount of damages.

Conversely, if it is deterioration from normal wear and tear—such as faded paint, leaking tap water, or fixtures that have aged with use—the tenant has no duty to be responsible, as this is considered the lessor’s responsibility under the housing lease law

3. Duty to return the property when the contract ends

Upon expiry of the lease, the tenant has a duty to return the house or rental unit in the same condition as received, except for damage resulting from normal use. If the tenant makes alterations or interior modifications—such as repainting, installing wallpaper, or changing the structure—without permission, the landlord has the right to demand reinstatement or claim damages.

If the tenant has not moved out after the contract term ends and continues to occupy the premises without the landlord’s permission, this will be considered unlawful possession, and the landlord may file a claim for return of the property and seek damages under the law.

4. Duty to comply with the terms of the residential lease agreement

A residential lease agreement is a mutual agreement between the tenant and the lessor, which both parties must strictly comply with—for example, not subletting the premises to others, not modifying the property without permission, and not using the property for illegal purposes.

If the tenant breaches these terms, the landlord has the right to terminate the contract immediately under Section 564 of the Civil and Commercial Code, and may claim damages if the property is damaged.

In summary, tenants’ duties are the other side of tenants’ rights, established by law to keep the relationship between tenants and landlords balanced. When tenants fully comply with their duties, they will be fully protected under the Residential Lease Contract Act and can effectively reduce the risk of future disputes.

Under Thailand’s residential rental laws, it is not only tenants’ rights that are protected; landlords’ rights (or lessors’ rights) are also clearly recognized, to ensure that the contractual relationship between both parties is fair and balanced.

1. Right to inspect and maintain the property

Landlords have the right to inspect the condition of the property from time to time to ensure it is properly maintained and ready for use. They must give prior notice to the tenant and obtain consent each time, except in emergencies such as water leaks, fire, or danger to life and property.

This right is intended to allow landlords to care for the property appropriately without violating the tenant’s right to privacy under residential rental law

For example, if a roof leak causes structural damage, the landlord may enter to carry out repairs after giving prior notice to the tenant, and this is considered a lawful right.

2. Right to receive rent as agreed

One of the most important landlords’ rights is the right to receive rent on the due date, which the tenant is obligated to pay on time. If the tenant defaults and fails to pay rent consecutively as specified in the agreement, the landlord has the right to terminate the lease and demand return of the property.

Section 560 of the Civil and Commercial Code clearly provides that if the tenant defaults on rent payment, the landlord may exercise the right to terminate the agreement without having to issue repeated reminders multiple times.

3. Right to terminate the lease when the tenant breaches the terms

Landlords may terminate the lease immediately if the tenant violates key terms, such as:

• Using the property for an improper purpose, such as operating a business in a home rented for residential use

• Subletting to others without permission

• Causing serious damage to the property

• Disturbing neighbors or using the property for illegal purposes

This right is recognized under Sections 564 and 571 of the Civil and Commercial Code and is an important mechanism that helps landlords protect their interests fairly.

4. Right to claim damages and deduct from the security deposit

If the tenant causes damage to the property or fails to return it in its original condition, the landlord has the right to deduct the actual damages from the security deposit, provided there is clear evidence, such as repair quotations or before-and-after photos of the damage.

However, if the lessor deducts more than the actual damage, it may be considered a violation of the Contract Committee’s Notification on Residential Lease Agreements, B.E. 2561 (2018), which prohibits landlords from taking unfair advantage of tenants beyond what is reasonable.

Recommendation: Landlords should take photos of the property before handover and prepare a property handover record to keep as supporting evidence in case of disputes.

It is not only tenants who must comply with legal requirements; landlords or homeowners also have duties clearly prescribed under the house rental law and the residential lease contract law to ensure that the relationship between both parties is fair, transparent, and able to coexist smoothly.

Thai law—especially Sections 537–571 of the Civil and Commercial Code, as well as the Notification of the Contract Committee on Residential Lease Agreements, 2018—sets out the landlord’s duties in a systematic manner, covering everything from the start of the tenancy through to the termination of the contract.

1. Duty to hand over the property in a usable condition

Before the tenancy begins, the homeowner’s key duty is to deliver the house or rental unit in a move-in-ready condition, pursuant to Section 544 of the Civil and Commercial Code. If the rented house or condo is defective—for example, lights not working, leaking pipes, or incomplete fixtures—this is deemed a failure by the landlord to perform their legal duty.

For example, if there is water leakage from the first day the tenant moves in, the homeowner must repair it immediately; otherwise, the tenant may refuse to accept delivery or request a rent reduction.

2. Duty to maintain and repair damaged parts

The homeowner has a duty to maintain and repair the property so that it remains in normal working condition throughout the lease term, pursuant to Section 548. This means that if damage occurs that was not caused by the tenant—such as a broken water heater, an electrical system malfunction, or a leaking roof—the landlord must arrange repairs promptly.

If the landlord neglects this duty, the tenant has the right to terminate the contract, or in some cases may carry out the repairs and deduct the cost from the rent as permitted by law.

3. Duty to prepare a clear and fair lease agreement

Landlords who rent out properties commercially—such as dormitories, apartments, or condos with multiple units—are subject to the Residential Lease Contract Law, 2018, which requires landlords to prepare a written lease agreement with terms that are fair to tenants, such as:

• Clearly stating the actual rent and service charges

• Not collecting advance payments exceeding 1 month

• Not forcing tenants to renew the contract or unfairly restricting their right to occupy

• Returning the security deposit within 7 business days after the property inspection is completed

A fair lease agreement not only gives tenants confidence, but also helps protect landlords from complaints under consumer protection laws.

4. Duty to return the security deposit within the prescribed timeframe

When the lease ends, the landlord must return the security deposit to the tenant within the period prescribed by law (7 business days) after inspecting the property’s condition. If damage is found, the landlord may deduct the actual costs incurred, but must provide supporting evidence such as photos or a repair quotation.

If the landlord refuses to return the security deposit without reasonable cause, the tenant may immediately file a complaint with the Office of the Consumer Protection Board (OCPB) right away.

5. Duty to respect tenants’ rights

One of the most important duties of a homeowner is to respect the tenant’s right to privacy. The homeowner has no right to enter the house or rental unit without permission, except in urgent necessity, such as a fire or a water leak that may cause serious damage.

Any act that interferes with tenants’ rights—such as arbitrary entry, cutting off water or electricity, or seizing property without authorization—is unlawful and may be subject to legal action under the house rental law

In the world of residential rentals, understanding rental law is a crucial foundation that helps the relationship between tenants and landlords run smoothly and transparently. Thai law clearly sets out the principles regarding tenants’ rights and landlords’ rights, including each party’s obligations, to prevent disputes and ensure fairness in every agreement.

Tenants should know their rights, such as the right to peaceful enjoyment without disturbance, the right to receive a home in move-in-ready condition, and the right to have the security deposit returned within the specified timeframe. At the same time, landlords must fulfill their duties, such as repairing the property, keeping the home in good condition, providing a fair lease agreement, and respecting the tenant’s privacy.

Residential lease law is not intended to protect only one side, but to enable both parties to live together with understanding and responsibility. Learning and complying with these laws not only helps reduce future disputes, but also reflects the professionalism of both landlords and tenants.

A key takeaway: before signing any lease agreement, you should read all details thoroughly, review fair terms and conditions, and never overlook your own rights—because the law is the best protection for both parties.
