If you’ve just collected the keys to a new HDB flat, the Building Service Centre, or BSC, will be your main contact for defects during the first year. This guide explains what the BSC does, how to submit defects, what happens at the joint inspection, how long repairs usually take, and how to avoid common delays.
HDB’s procedures are updated from time to time. Always check the Welcome Kit for your project and HDB’s website for the latest instructions.
What is the BSC?
When a new HDB project is completed, HDB opens a temporary Building Service Centre within walking distance of the blocks. Its job is to handle rectification of defects in new flats during the 1-year Defects Liability Period (DLP), which starts on your key collection date. Your Welcome Kit tells you where your BSC is and when it’s open.
The BSC can:
– receive your defect reports (rectification requests);
– arrange a joint inspection to verify what you reported;
– assign HDB’s contractors to fix the items;
– arrange a closing inspection with you when the work is done.
Step 1: Inspect your flat early
HDB asks owners to report defects within one month of key collection and before renovation starts. The reason is practical: once renovation work begins, it’s difficult to tell whether a defect came from HDB’s contractor or yours.
Plan to inspect the flat in the first week or two after key collection. You can do it yourself or hire a defect inspector. Either way:
- go through each room systematically;
- mark defects with painter’s tape or sticky notes;
- write each item down with its location (for example, “Master bathroom, floor tile near floor trap, hollow”);
- take photos;
- test things: run taps, flush toilets, use switches and sockets, and check floor drainage.
Don’t list normal material characteristics. HDB says slight colour variations in tiles or timber, and small differences in grout width, aren’t defects. Keeping your list to genuine items helps the BSC deal with it faster.

Step 2: Submit your rectification request
You can submit defects in two ways:
- Online: scan the QR code in your Welcome Kit, or on the notice in your kitchen, and submit a rectification request.
- In person: at the BSC in your precinct, during its opening hours.
Tips for a smooth submission:
– Submit one consolidated list rather than many small reports.
– Be specific about location and what’s wrong.
– Attach photos where the channel allows it.
– Keep your own copy of the list and a record of when you submitted it.
– Tell the BSC your renovation start date so rectification can be scheduled around it.
Many owners search for a “BSC appointment” at this stage. In practice, the BSC contacts you or sets the joint inspection after your request. /p>
Step 3: The joint inspection
After receiving your request, the BSC arranges a joint inspection. BSC staff come to your flat to look at the items you reported and confirm what needs rectifying.
How to prepare:
– Leave your markings in place (tape or sticky notes) so each item is easy to find.
– Have your list ready, in the same order as your submission.
– Make sure water and electricity are on so items like drainage, leaking taps and faulty sockets can be shown working, or not working.
– Ask questions if an item isn’t accepted, and note the reason.
If you’ve engaged a defect inspector on a package that includes it, they can attend the joint inspection with you and explain each item.
Step 4: Rectification
The BSC assigns contractors to fix the verified items. HDB says it usually takes less than two weeks to complete the repairs. A few practical points:
- Coordinate access. Contractors need to get into your flat, so agree times with the BSC.
- Renovation clashes. If your renovation can’t wait, HDB may carry out rectification during the renovation, if it doesn’t get in the way, or afterwards. Some minor defects can be fixed after you move in, if they don’t affect your living conditions.
- Protect finished work. If rectification happens alongside renovation, make sure your contractor doesn’t cover up or damage items waiting to be fixed.
Step 5: The closing inspection
When the work is done, the BSC arranges a closing inspection with you. This is your chance to confirm that each item has been fixed properly.
- Go through your original list item by item.
- Test repaired items again: run the taps, check drainage and try the doors.
- Raise anything that isn’t satisfactory before you sign off.
After the closing inspection
Your DLP continues until one year after key collection. If new defects appear during that time (seepage, for example, can take a while to show), report them to the BSC. After the DLP, repairs are generally the owner’s responsibility, and you can approach your HDB Branch if you need help. HDB notes that under the Agreement for Lease, owners are responsible for keeping the flat’s fittings and fixtures in good condition.
HDB has said that the BSC operates on site for a year. [Flag: HDB’s own web page calls it a “temporary” BSC and refers owners to the Welcome Kit for availability, so check your kit for your project’s dates.]
Typical BSC timeline
| When | What happens |
|---|---|
| Key collection (Day 0) | DLP starts; Welcome Kit shows BSC location, hours and QR code |
| Week 1–2 | Inspect the flat; compile and submit your rectification request |
| Shortly after submission | BSC arranges the joint inspection |
| About 2 weeks after the joint inspection (HDB: usually under 2 weeks) | Contractors carry out repairs |
| After repairs | Closing inspection with the BSC |
| Up to 1 year after key collection | Report any new defects that appear during the DLP |
Actual timings depend on your project and how many items you report.
Common BSC mistakes to avoid
- Renovating before submitting. This makes it harder to attribute defects to the original construction.
- Sending lots of partial lists. One clear, consolidated list is easier for everyone.
- Removing markings before the joint inspection. Items get missed.
- Skipping the closing inspection. You lose your best chance to check the repairs.
- Listing normal material variation. It slows the process and weakens the credibility of your genuine items.
How we help with the BSC process
Our BTO defect check packages are built around these steps:
- Bronze (1 trip, from $95): one full inspection, a report with photos, submission of the defect report to the BSC, and guidance on the DLP process. We can fill in the defect form for you so it’s ready immediately.
- Silver (3 trips, from $145): everything in Bronze, plus we coordinate and attend the joint inspection and the final inspection with you and the BSC.
- Gold (5 trips, from $245): everything in Silver, plus a post-renovation inspection with its own report.
We also include BSC liaison, a defects guide and lifetime offsite consultation. See the full price list.

BSC FAQ
Where is my BSC?
It’s a temporary centre near your project. The location and opening hours are in your Welcome Kit.
Can I submit defects online?
Yes. Scan the QR code in your Welcome Kit or on the notice in your kitchen to submit a rectification request. You can also submit at the BSC.
How long does the BSC take to fix defects?
HDB says repairs usually take less than two weeks. Timing depends on the items involved and on access to your flat.
What if the BSC doesn’t accept an item?
Ask for the reason and note it. If you think it’s a genuine defect, provide clearer photos or details and follow up with the BSC or HDB.
Can someone else attend the joint inspection for me?
Many owners have a family member or their defect inspector attend. Check with your BSC beforehand whether the owner needs to be present.>
