What the warranty period after property handover means
After receiving the keys, a buyer may discover issues that were not visible during the initial inspection: water leaks, faulty building systems, cracks, damaged tiles, misaligned doors or problems with installed equipment. The warranty period determines which defects the developer must repair after handing over a condominium unit or villa.
In Thailand, liability depends on the property type, the sale and purchase agreement, the handover documents and the nature of the defect. Finishes and installed equipment generally have shorter coverage, while major structural components may be covered for a longer period. The exact terms must be checked in the contract for the specific development.
Buyers comparing new developments and completed property in Phuket or exploring condominiums and residential projects in Pattaya should review the warranty clauses before signing. It becomes considerably harder to negotiate contractual wording after the transfer has been completed.
Which defects the developer should repair
The developer is responsible for defects connected with construction quality, finishing work and equipment supplied as part of the property. These may include leaks from roofs, balconies or windows, defective bathroom waterproofing, wall cracks, uneven flooring, loose tiles and improperly fitted doors or windows.
Responsibility may also cover defects in electrical wiring, water supply, drainage, ventilation and air-conditioning systems when they form part of the agreed specification and were installed by the developer. When the owner replaces equipment or hires independent contractors, establishing the developer’s liability can become more difficult.
Normal wear, damage caused during renovation, improper use of appliances and alterations made by the owner are generally outside the scope of developer repairs. The condition of the property should therefore be documented before moving in or beginning any additional work.
Structural and non-structural defects
Non-structural defects affect finishes, plumbing fixtures, electrical fittings, doors, windows, built-in furniture and installed equipment. They are often discovered during the first months after handover, when the owner begins using the property regularly.
Structural defects concern foundations, load-bearing walls, columns, slabs, beams and major roof structures. These issues may appear later and usually require a technical assessment. A large crack, significant floor settlement or persistent water penetration may indicate a deeper problem that should not be treated as a cosmetic repair.
It is not always possible for an owner to classify a defect correctly. For serious damage, an inspection report from a qualified building inspector or engineer can provide useful evidence for a formal claim.
When the warranty period begins
The starting date may be the handover date, the date the acceptance document was signed, the ownership registration date or another date specified in the contract. Buyers should identify the relevant clause and retain copies of the agreement, schedules, handover report, specification and correspondence with the developer.
Different components may have separate warranty periods. Structural coverage may differ from the warranty for air-conditioning units, plumbing fixtures, appliances or furniture. Some equipment may also carry a separate manufacturer’s warranty.

How to document defects correctly
Each defect should be photographed and recorded on video. The material should show the damaged area, its scale and enough of the surrounding space to identify the room or location. Buyers should also prepare a written list describing each issue, the date it was discovered and the repair requested.
The claim should be sent in writing to the developer, its after-sales department or the property management team when it is authorised to process warranty requests. The notice should include the unit number, building, owner’s contact details and all supporting evidence.
A verbal discussion with site staff is not sufficient. The buyer should obtain a claim reference number, an email confirmation or a signed copy of the submitted notice. This record helps establish that the problem was reported within the applicable warranty period.
How quickly the developer should complete repairs
There is no single practical repair period for every type of defect. A minor finishing issue may be resolved quickly, while replacement equipment, leak investigation or repairs to shared engineering systems may require more time.
The buyer should ask the developer to confirm the inspection date, the accepted defect list and the proposed repair schedule. Once the work has been completed, the affected area should be inspected again. The claim should only be closed after the defect has genuinely been resolved.
When repairs are delayed, the owner should send a follow-up notice referring to the original claim and the relevant contract terms. Emails, photographs, inspection reports and records of expenses caused by the defect should be retained.
What to do if the developer refuses to repair a defect
The first step is to request a formal written explanation. The developer may claim that the damage occurred after handover, resulted from normal wear or was caused by alterations made by the owner. In such cases, an independent technical report becomes particularly valuable.
The next step may be a formal written claim citing the contract provisions, handover date, discovery date and previous notices. Where there is substantial damage or a dispute involving structural safety, the documents should be reviewed by a Thai lawyer who can assess the agreement and the available remedies.
A warranty provides useful protection only when its terms are understood in advance. Before purchasing, buyers should check the duration, exclusions, claim procedure and after-sales contact details. It is also sensible to review the contract terms and developer payment schedule that require particular attention, since both payment and post-handover obligations should be recorded in writing before completion.
