New-Build Condo Handover in Thailand: What to Check Before Getting the Keys
Quick — 10-second read
- In short
- A useful handover inspection does two things: it checks the condo against the contract and agreed specification, then tests the systems that can actually be operated on the day. Every defect should end up in a written record that is specific enough to find and verify again.
- Who it matters to
- For a buyer of a developer unit who has been invited to inspect before handover, final payment, ownership transfer or key release. Those events do not follow one universal sequence in Thailand, so the signed contract and project documents control the order.
- Next step
- Before the visit, gather the contract, plans, finish schedule, furniture and appliance list, approved changes and the handover form. Finish with your own copy of the defect record, clear status for every open item and an agreed route for reinspection.
This is a guide, not legal, tax or investment advice.
What a pre-handover condo inspection actually covers
A handover visit can easily turn into a hunt for visible scratches and chips. The more disruptive problems often appear only when the unit is used: water shows under a sink after the tap has been running, a balcony drain leaves standing water, a window binds, or an air-conditioning unit starts dripping after it has been on for a while.
The inspection is about documenting your specific unit and checking it against the contract, plans and agreed specification. It is not a structural survey of the whole building, and an observation is not a diagnosis. Record a damp mark, crack or unusual noise precisely; do not guess at the cause when specialist investigation would be needed.
There is no single legal handover sequence for every Thai development. Inspection, final payment, ownership registration and key release can occur in different orders, and signatures can acknowledge different things. Whether a form should be signed therefore depends on the actual document and contract.
If time is tight, prioritise issues that become harder to prove or more disruptive to fix after delivery: water and drainage, windows and balcony junctions, electrical function, air-conditioning and the promised fit-out. Cosmetics still matter, but perfect paint does not compensate for a dead socket or a wet cabinet.
What to bring: contract, plans and the agreed specification
The most valuable thing to bring is the paper trail that says what this particular unit was supposed to be. Have the signed contract and attachments, unit plan, finish schedule, furniture and appliance list, approved variations and any material written promises. If a finish or appliance model was substituted, the approval record matters more than anyone's memory at the door.
Use the plan to spot meaningful discrepancies: a changed door arrangement, missing niche, different fitted furniture or equipment installed away from an agreed position. A tape measure is useful for a specific question, not for an amateur survey. Household measurements do not replace the formal area or create universal millimetre tolerances.
Live water and power are essential for functional testing. Without them you cannot meaningfully test taps, toilets, drains, lighting, sockets, air-conditioning or supplied appliances. If the project still holds the inspection, record exactly what could not be tested and establish when follow-up access will be available.
A charged phone with storage, torch, tape measure, tissues for spotting drips, removable labels and a charger or simple safe socket tester are usually enough. Opening a live distribution board, dismantling plumbing, accessing a façade or creating an improvised flood test crosses into work for qualified personnel.
Decide how you will number defects before the visit. A photo labelled bathroom 07 that matches item 07 in the written log is far easier to recheck than an anonymous close-up buried in the camera roll.

Finishes, tiles, windows and balcony: where defects hide
Start with the room, not the grout line. A first pass should tell you whether the layout makes sense against the plan, whether spaces are actually complete, and whether there are obvious signs of damp, significant cracking, binding doors or unfinished areas. Only then move closer to paint, flooring, tiles, skirting and joinery. Otherwise it is surprisingly easy to spend the visit documenting a minor chip while missing an issue that changes how the room functions.
Tile inspection is a good example of why observations and diagnoses should be kept separate. A different sound from gentle tapping may justify marking an area for the developer to investigate, but it does not by itself prove a concealed installation defect or its cause. Visible cracks, chips, damaged grout and clear movement under normal use are much easier to document. Avoid importing a random millimetre tolerance from the internet when the project specification and actual contract are the relevant reference points.
Treat windows and doors as moving systems. Open them fully, close them, operate the locks and look at the seals. A door that scrapes the floor can become a recurring finish problem, while a window that does not latch or leaves an obvious gap is more than a cosmetic complaint. Note visible damage to glass and frames before the unit is occupied so there is a clean record of condition.
Balconies deserve a separate pass because drainage, thresholds, sealant and external junctions all meet in one small area. Standing water near the door, old damp staining, visibly failed sealant or a drain that backs up should be recorded by exact location. Where the project allows it, a small controlled amount of water can show whether the drain is functioning. An improvised hose test of the façade is not a buyer-level handover check.
Built-in furniture also needs more than a presence check. If the specification includes a wardrobe or fitted cabinet, confirm that the promised item is there, operates normally and is not already damaged. Disputes about a substituted finish or missing component are far easier to discuss when the written specification is sitting beside the observation.
Plumbing and wet areas: test leaks and drainage under use
Plumbing often looks fine until it has been used for more than a few seconds. A connection under the basin may start to bead after a minute, water may gather at the shower threshold, and a drain may cope with a tiny flow but struggle during longer use. Ordinary operation is therefore more useful than an elaborate collection of test equipment.
After running a tap and drain, inspect visible connections, the trap, cabinet base and wall behind it. Dry tissue can reveal a small drip on a shiny pipe. In the bathroom, look at sealant, fixture junctions, the shower enclosure and where water actually travels during normal use.
Flush the toilet several times and watch the base and visible supply as well as the bowl. Persistent trickling, water on the floor, unusual odour or poor drainage can be recorded without guessing at the cause. If a water heater is included, keep the check to safe basic operation and do not open the casing or touch internal electrical parts.
Balcony drainage belongs in the same risk conversation. Standing water near a threshold or a drain that obviously struggles should be its own item. Damp staining, blistered paint or a wet corner should also be logged as observations; none of them identifies the source on its own.
There is no need to block a drain or deliberately flood the room. The aim is to observe the plumbing under ordinary use. Slow drainage, backup or water appearing where it should not be is enough to create a separate defect entry without trying to reproduce a failure.
Electrics, air-conditioning and appliances: test function, not presence
Electrical checks at handover are about accessible function, not amateur fault-finding. Lights should operate, switches should control the expected circuits and accessible sockets should power an ordinary safe device. If a point is dead or a switch appears to do nothing, record the room and exact location. The distribution board can be checked visually for basic completeness and labelling, but a buyer should not open a live panel to investigate the wiring.
Sockets are easy to miss unless you work through the unit methodically. A phone charger or suitable simple tester can confirm that power is present, but it does not certify the electrical installation. Repeated tripping, heat, burning smells, visible damage or other alarming behaviour is a reason to stop the household-level test and have the issue assessed properly.
Air-conditioning needs operating time. Turn on each indoor unit, confirm that the controls respond, listen for unusual noise or strong vibration and watch for water appearing where it should not. There is no useful universal rule that every room must reach a particular temperature within a fixed number of minutes; room size, solar gain, starting temperature and equipment capacity all affect that. At handover, you are looking for normal basic operation, not conducting a laboratory performance test.
Condensate problems may not appear immediately. A unit can start perfectly and begin dripping only after moisture has accumulated. Water from the indoor unit or dampness around the pipe route should therefore be recorded as its own defect, with the time and location noted. The cause can be investigated later without the buyer trying to diagnose the drain or installation on site.
For built-in appliances, first confirm what was actually promised, then perform a basic start-up where it is safe to do so. A substituted model is not automatically a breach if the change was properly agreed, but it should not come as a surprise when the model or specification formed part of the deal. An error message, missing component or obvious operating fault is more useful evidence than a photograph of an appliance that was never switched on.
How to record defects so they can be rechecked
Scratch in bedroom becomes almost useless two weeks later. There may be several wardrobes, doors and similar surfaces in that room. A good defect entry passes a simple test: could someone who missed the first inspection use the record to find the same issue? If yes, reinspection becomes verification. If not, the conversation quickly turns into an argument about what the note was supposed to mean.
Give every item an ID, room and precise location. Bathroom, vanity cabinet, left-hand connection: drip appears after tap runs is much stronger than plumbing installed incorrectly. The second version claims a diagnosis that the inspection may not support. Record the observable fact first; it can be photographed, reproduced and checked again after repair.
Use two photos where possible. An overview establishes location, while a close-up shows the defect. A macro image of a hairline mark with no context can be impossible to place later, and a wide room photo may not show the detail at all. Keep the original files rather than relying only on compressed images in a chat thread.
Priority is useful because five cosmetic items should not consume the conversation while an active water issue is still open. Water and potential damage come first, then failed systems, missing promised scope and finally finish items. That is a practical triage tool, not a legal ranking and not an excuse to ignore cosmetics.
Each item also needs a status that survives the conversation. Accepted for repair, disputed, awaiting investigation, repaired or ready for reinspection are useful only if they are tied to the same defect ID. If a completion date or next appointment is agreed, keep it in writing. Do not assume that one generic number of days applies across every Thai project; the contract, handover documents and actual agreement between the parties matter.
Closing a defect is a separate step from hearing that the contractor has finished. A repaired door may still scrape, a leak may recur, and the repair itself may damage another surface. Reinspection works best when you reopen the same numbered item, go to the same location and test the same observable problem.
Red flags during a condo handover inspection
Inspection with water or power unavailable
The unit can look complete while plumbing, drainage, sockets, air-conditioning and some appliances remain impossible to test.
The handover is being treated as complete even though functional testing has not happened.
List every untested system in writing and establish follow-up access.
Defects exist only in the developer's internal system
Items are entered into the developer's app or internal sheet, but the buyer receives no durable copy of the full record.
After the visit, it becomes difficult to prove which items were recorded and what status they had.
Obtain an export, email, signed attachment or other durable record containing the defect IDs.
We'll fix it after handover — with no date or status
The issue is acknowledged verbally but does not appear in the written record and has no reinspection path.
The promise cannot be tied to a specific item or verified later.
Tie the promise to a defect ID, written status and a clear next verification point.
Rushed inspection or restricted access
Part of the unit, furniture or equipment cannot be accessed even though the form covers the unit as a whole.
The buyer is pushed to close the inspection without recording what remained untested.
Record the limitation and arrange additional access before the affected items are closed.
A repaired defect is closed without reinspection
The item is marked complete after a contractor update before the buyer has seen the result.
Neither the repair quality nor any new surrounding damage has been verified.
Return to the same defect ID and verify the original issue on site.
What to sign at handover and what should remain open
The risky shortcut at this stage is looking for one rule that applies to every project. “Never sign if any defect remains” sounds decisive, but without seeing the actual form and contract it can be as unreliable as “sign now, they will fix everything later.” The real question is what the document says the signature acknowledges: an inspection, the unit's condition, delivery, key receipt, acceptance, waiver language, or some combination of those things.
Also read how the contract connects inspection with final payment and ownership registration. Thai developments do not all sequence those events identically. If a clause is unclear or the consequences of signing are disputed, a generic article cannot resolve the legal effect of that specific wording. That requires contract-specific review.
Where defects remain, the practical issue is keeping those items visibly open. Each one should stay tied to an ID, description, status and the next agreed step or completion date. If the project uses an attachment to the handover form, make sure the open items are actually captured there or in another durable record. The buyer should retain a copy outside a developer-only system.
Thailand's Office of the Consumer Protection Board advises consumers to retain contracts, payment evidence and correspondence when disputes arise. In a case published in August 2026, defects identified during inspection included water leakage, a non-functioning water heater and wall cracks; the matter ended in a refund through that particular mediation process. It is useful evidence that defect documentation can matter, but it is not a rule that every defect creates an automatic right to a refund.
A dispute over a major defect, refusal to complete handover, withholding a final payment or terminating the purchase goes beyond a general inspection guide. The answer depends on the signed contract, the handover wording, payment status and the actual facts. Preserve the evidence first, then have the specific documents reviewed instead of importing a result from someone else's case.
A practical handover sequence
Before the visit
Collect the contract, attachments, plans and specification, and confirm whether live water and power will be available.
Scope and finishes
Start with the plan and promised scope, then work through finishes, windows, doors, fitted furniture and balcony.
Systems in operation
Run water, drains, lighting, sockets, air-conditioning and appliances long enough to expose obvious functional faults.
Defect log and paperwork
Number the items, attach photographs, record each status and keep your own copy.
Reinspection
Return to the same defect IDs and close them after verifying the repair, not merely after receiving a contractor update.
Reinspection and the warranty period after handover
Reinspection is mainly about the open items. The same defect ID should take you back to the same place and the same observable problem: the door now clears the floor, the cabinet stays dry after water runs, or the air-conditioning unit no longer drips. That verifies the outcome rather than relying on a contractor update.
Look around the repaired area as well. Replacing a tile can damage adjacent grout, adjusting a door can chip a finish, and fixing a leak may leave the cabinet needing further work. Record new damage separately so the history remains clear.
By handover, collect the keys, access cards, remotes, equipment manuals, handover documents and meter readings where the project uses them. Also know how warranty issues are reported after key release. Do not import one generic warranty period: timing and procedure come from the signed contract and project documents.
Handover records the unit's condition before or at delivery. A defect that remains, recurs or appears later belongs to the post-handover warranty process. Keep the original log, photographs and correspondence after key release; a serious technical or contractual dispute may require appropriate engineering or contract review.

Expert view

A small scratch announces itself immediately; a leak under a vanity may not appear until the water has been running for several minutes. My priority is therefore the stuff that becomes disruptive and expensive once the condo is occupied: water, windows, balcony junctions, electrics, air-conditioning and the promised fit-out. Every issue needs a precise location, a photo and its own ID or reinspection turns into detective work. I would not close an item simply because a contractor says it is done—the unit should demonstrate that the original problem has actually gone.
