BTO key collection day: what to prepare, inspect, refuse.

What actually happens at the BSC

You receive an appointment letter from HDB with a date, time, and Building Service Centre (BSC) location for your project. You arrive, present your IC, sign in. A site engineer or HDB staff member walks you through the unit. They explain the systems, show you the meter and isolator locations, hand you the keys.

The walkthrough is usually short. The appointment also covers signing the lease and handing over the keys, and the whole thing is typically done within the hour. The engineer points out features and answers questions. Defects you spot on the day get noted on a clipboard form, but the engineer’s job is to close the handover, not to compile your full defect list.

You then sign the acknowledgment of receipt. From that signature, your 12-month DLP begins. You have up to 30 days from key collection to submit all defects via the Defects Feedback Form: the QR code in your HDB Welcome Kit works from key collection itself, or file at the BSC counter. Renovation must not start before you submit.

What to bring

• Printed defect checklist. Use HDB’s official Defects Feedback Form, or print our BTO handover checklist. A paper list survives a dropped phone; an electronic one syncs back later.
• Torch. Phone torches work but drain battery and slow you down. A dedicated torch reveals hairline cracks and finishing defects that overhead lighting hides.
• Phone with full battery and storage. Between the walkthrough, defect documentation, and meter readings, you will take a lot of photos. Start the day with the battery full and enough free storage so you never have to stop and delete.
• Tape measure. Useful for checking door clearances, tile alignment, and noting the size of cracks for later reference.
• Polarity tester (optional but useful). A cheap plug-in tester from any hardware shop. Plug it into every socket; reversed live and neutral light up immediately. If you cannot bring one, the inspector will catch it later, but it is the easiest defect to flag on day one.
• A second person. One walks and points; the other photographs and notes. The walkthrough is faster and more thorough with two pairs of eyes.

What to inspect before you sign

You do not have to refuse acknowledgment to record defects. The signature confirms you received the keys; it does not waive your right to flag defects within the 30-day submission window. But the obvious things should still be noted at the walkthrough. HDB and the contractor will work from your initial list when scheduling the joint inspection.

In the time available, focus on:

• Walls and ceilings. Look at every wall in oblique light from the torch. Note paint runs, missed spots, hairline cracks, plaster bumps, and any stain that suggests prior water exposure.
• Doors and windows. Open and close every door. Doors should latch on first attempt and stay where you put them. Windows should open fully and seal cleanly. Sliding doors should not stick or skip.
• Tiling. Walk every tiled surface. Note any visibly uneven tiles, broken edges, or wide grouting gaps. Hollow tiles require a tap-test; you can do a basic version with a coin, but a full inspection uses a small mallet.
• Plumbing. Run every tap. Watch the drain trap. Flush every toilet. Check shower and basin water pressure. If a tap drips, leaks at the base, or runs slow, photograph it.
• Electrical. Test every socket with your polarity tester. Flip every switch. Note any socket that produces a warning light, any light that does not work, or any switch that feels loose in its plate.
• Bomb shelter. Open and close the door. The rubber seal should sit flush all the way around. Note the SCDF certification sticker (or its absence). If the door does not close cleanly, that is a regulatory issue.

What you can legitimately refuse

You can refuse to accept handover if the unit has serious obstructions to occupation: for example, water supply not turned on, missing major fittings, or a blocked door. In practice, HDB and the contractor will not deliver a unit with these issues. The decisions that actually matter are about defects to record, not handover to refuse.

If something seems badly wrong, ask the engineer to schedule a joint review before you sign. Refusing to sign on handover day is rare. Reserve it for something serious, such as a major plumbing failure during the walkthrough or a structural concern visible in the unit.

The 30-day window starts now

Once you sign, you have up to 30 days from key collection to submit your full defect list to HDB, or until you begin renovation, whichever comes first. The Defects Feedback Form is reachable from day one via the QR code in your Welcome Kit, or at the BSC counter. Both produce a reference number; keep that number.

HDB then reviews the list and schedules a joint inspection with the main contractor. At that joint visit, the contractor sees each defect on your list, agrees or contests, and arranges rectification. Defects you missed during your initial submission can sometimes still be added within the 30-day window, but the joint inspection is your strongest leverage point and works from your submitted list. Inspect thoroughly and submit early.

After collection

Do not move in immediately. Do not start renovation. The 30-day submission window is for documentation; the joint inspection and rectification happen over the following weeks. Moving furniture and beginning renovation work before that close compromises your claim against hollow tiles, hairline cracks, and finishing defects that surface under use.

Bookmark your reference number. Take a final round of photos at the end of day one, before you leave. Save them with date metadata intact. They are your independent record of unit condition at acceptance.

The technical depth of each defect category (hollow tile detection, drainage gradient testing, RCD trip verification, bomb shelter compliance) lives in the Toolkit and the common defects catalogue.
