How to Submit Your BTO Defect List to HDB (BSC) — Step by Step (2026)
A plain-English guide to reporting defects to your HDB Building Service Centre: how to submit, what HDB will and won’t fix, how long it takes, and what to do if your claim is rejected.
To report defects in a new HDB flat you submit a rectification request to your Building Service Centre (BSC) — online through the HDB website or in person at the BSC in your precinct — ideally within 30 days of key collection and before renovation. HDB then arranges a joint inspection and rectifies genuine defects at no cost to you, usually within about two weeks. Here is exactly how to do it, and how to make sure your list is accepted.
The short version
- Submit defects to your Building Service Centre — online or in person — within your 1-year Defects Liability Period.
- Report within 30 days of key collection, before renovation, for the cleanest claim.
- HDB rectifies genuine workmanship and material defects at no cost; it will not treat natural material variation as a defect.
- A photographed, located, consolidated list is accepted far faster than a vague verbal complaint.
- If an item is declined, you can re-submit with evidence or approach your HDB Branch for assistance.
What is the HDB Building Service Centre (BSC)?
The Building Service Centre is HDB’s on-the-ground team for your precinct, responsible for rectifying defects in newly completed flats during the Defects Liability Period. When people search “BSC HDB” or ask how to complain about their new flat, this is the office they are looking for. You deal with the BSC for everything from your first defect submission through the joint inspection to signing off the completed repairs.2
How to submit your defect list — step by step
- Inspect the bare flat first. Walk it room by room before renovation, ideally within your first week. A full BTO checklist keeps you from missing anything.
- Consolidate one list. Every defect with a clear description, exact location and a dated photo — grouped by room, not scattered across messages.
- Submit to your BSC — online via the HDB website’s defect-reporting e-service, or in person at your precinct’s Building Service Centre.
- Attend the joint inspection. HDB inspects the flagged items with you, confirms which are accepted, and schedules the repairs.
- Verify the rectification. When HDB reports the work done, re-check each item before you sign off — and before you renovate over it. 1,2
What will HDB fix — and what won’t it?
During the Defects Liability Period, HDB rectifies genuine workmanship and material defects at no cost. What it will not do is treat normal material characteristics as defects — and knowing the difference keeps your list credible.
| HDB will rectify | HDB will not treat as a defect |
|---|---|
| Hollow or debonded floor tiles | Natural colour variation in floor tiles or timber flooring |
| Cracked, chipped or lipped tiles | Variation in tile grout width |
| Water seepage and failed waterproofing | General wear and tear after you move in |
| Doors and windows that don’t align or seal | Damage caused during your own renovation |
| Faulty or mis-wired electrical points | Cosmetic preferences (paint shade, finish choice) |
Keeping non-defects off your list is not just tidiness — it protects the credibility of the genuine items on it. A list padded with grout-width complaints invites the whole submission to be waved away.
What if HDB rejects a defect claim?
If HDB declines an item you believe is a real defect, you have options. Ask for the reason, then re-submit with better evidence — clearer photos, a wider shot showing the location, and a plain explanation of the fault (for example, a percussion-tested hollow area rather than “the tile looks off”). If it still isn’t resolved, you can approach your HDB Branch for assistance. This is where an independent inspector earns their fee: a professional report frames each finding against recognised standards, which is much harder to dismiss than an owner’s description.2
How long does rectification take?
Once accepted at the joint inspection, straightforward repairs typically complete within around two weeks, though it varies with the defect and the workload in your precinct. The submission-to-fix sequence is the reason to report early: start on day 5 and you have the whole year of buffer; start on day 300 and a slow rectification can bump against the end of your window. For how the underlying warranty works, see our guide to the Defects Liability Period.
HDB doesn’t reward the owner who complains the loudest — it rewards the one who documented the most, the earliest.
Frustrated searches for “how to complain to HDB” almost always trace back to a submission that was vague or late. Get the list right, submit it early, and the process is far more cooperative than its reputation. If you would rather hand the whole thing off, our HDB BTO defect check includes the inspection and joint submission to your BSC.
Frequently asked
How do I submit defects to HDB?
Submit a rectification request to your Building Service Centre (BSC), either online through the HDB website’s defect-reporting e-service or in person at your precinct’s BSC. Do it within your one-year Defects Liability Period — ideally within 30 days of key collection and before renovation — with a consolidated, photographed list.
What is the BSC in HDB?
The Building Service Centre is HDB’s local team for your precinct that handles rectification of defects in newly completed flats during the Defects Liability Period. You deal with the BSC from your first defect submission through the joint inspection to signing off the repairs.
What will HDB not fix as a defect?
HDB does not treat natural material characteristics as defects — for example, colour variation in floor tiles or timber flooring, or variation in tile grout width. General wear and tear after move-in and damage caused by your own renovation are also excluded.
What can I do if HDB rejects my defect claim?
Ask for the reason, then re-submit with stronger evidence — clearer photos, the exact location, and a plain description of the fault. If it is still unresolved, approach your HDB Branch for assistance. An independent inspection report that frames each finding against recognised standards is much harder to dismiss.
How long does HDB take to fix defects?
Once accepted at the joint inspection, straightforward repairs typically complete within about two weeks, though it varies with the defect and your precinct’s workload. Reporting early in your one-year window leaves buffer if a repair drags.
