The first year after collecting the keys to a new HDB flat is not an ordinary year.
It is a temporary responsibility state.
HDB currently gives all newly completed flats a one-year Defects Liability Period, or DLP, beginning from the date of key collection.
During that period, defects attributable to the original construction can be reported, inspected and rectified through the HDB defects process.
After that year ends, the operating assumption changes.
HDB’s current guidance states that homeowners are responsible under the Agreement for Lease for keeping the fittings and fixtures in their flats in good condition and should engage a repair contractor for issues arising after the DLP.

This article reflects HDB guidance available on 4 September 2026.
Quick Answer
The current HDB DLP runs for one year from key collection.
During the DLP, owners can report items requiring rectification through the Building Service Centre or HDB’s online channel.
HDB strongly advises owners to report defects within one month of key collection and before renovation begins. This makes it easier to distinguish an original construction defect from damage or alteration caused by subsequent renovation.
After the one-year DLP, HDB’s current guidance says owners should engage a repair contractor for issues in the flat, although the HDB Branch can still be approached if further assistance is needed.
KEY COLLECTION → 1-YEAR DLP → REPORT / INSPECT / RECTIFY ORIGINAL DEFECTS → DLP ENDS → ORDINARY HOMEOWNER MAINTENANCE STATE
Wait, What? The DLP Is Not a One-Year Warranty Against Everything
The easiest way to misunderstand the DLP is to treat it as a blanket promise that anything going wrong in the first year belongs to HDB.
That is not the useful distinction.
The real question is whether the reported condition is an original construction defect requiring rectification or whether it arose from use, renovation, damage, maintenance or some other later cause.
Time matters.
Cause matters more.
Why HDB Says Report Within One Month
HDB specifically advises new owners to report defect items within one month of key collection and before renovation begins.
The purpose is evidential clarity.
An untouched flat still largely reflects the construction state handed over by HDB.
A renovated flat contains new tiles, hacked walls, altered services, carpentry, drilling, waterproofing work and contractor activity.
Once those interventions begin, cause becomes harder to assign.
EARLY REPORTING PRESERVES THE ORIGINAL STATE AS EVIDENCE.
The Building Service Centre Exists for a Temporary Phase
HDB sets up a temporary Building Service Centre, or BSC, near new precincts to receive defects feedback and coordinate rectification.
After a defect is reported, the BSC can arrange a joint inspection, verify the item and assign the relevant contractor for rectification.
When the work is completed, a closing inspection can be arranged with the owner.
The BSC therefore belongs to the transition between:
NEWLY CONSTRUCTED PRODUCT
and
ORDINARY OCCUPIED HOME.
Rectification Usually Happens Before Renovation for a Reason
If a defect sits behind future cabinetry, under new flooring or beside a wall scheduled for alteration, rectifying it first is usually cleaner.
HDB notes that where renovation cannot wait, defect rectification may still be done during the renovation if it does not hinder the works, or afterward. Some minor defects may also be rectified after move-in if living conditions are not affected.
But the principle remains:
resolve the original building state before layering a private renovation state over it wherever possible.
The DLP Clock Starts at Key Collection
HDB’s current guidance is explicit that the one-year period runs from the date of key collection.
It does not wait for:
- the day renovation begins;
- the day the household moves in;
- the day every defect is discovered;
- the day furniture arrives.
This makes key collection a legal and operational transition point.
What Actually Changes on Day 366?
The flat does not suddenly become old.
A defect does not become physically different because the calendar moved one day.
What changes is the default responsibility framework.
During DLP, there is a dedicated construction-defect rectification channel.
After DLP, the flat operates under the ordinary homeowner maintenance obligation unless another responsibility owner applies, such as common property maintained by the Town Council or a separate HDB programme.
After DLP Does Not Mean “Never Contact HDB Again”
HDB’s own guidance says that if the DLP has passed, owners can engage a contractor for the necessary repairs and may approach their HDB Branch if further assistance is needed.
This is important.
The DLP ending does not erase HDB from the housing system.
It ends one specific defects channel.
Some Problems Belong to the Town Council Instead
A leak from the block roof is a common-property problem, not an expired-DLP bathroom defect.
A broken lift is common property.
A failed corridor light is common property.
The expiry of the flat’s DLP does not transfer Town Council responsibilities to the homeowner.

Some Problems Become Shared Between Neighbours
Inter-floor ceiling seepage is the classic example.
The visible stain may be in the lower flat while the water path begins in the upper flat.
HDB’s current guidance treats affected owners as jointly responsible for arranging repair of the relevant floor/ceiling slab condition and sharing the costs under the applicable framework.

Renovation Can Change the Evidential Boundary
HDB’s advice to report before renovation is not merely administrative.
Renovation can introduce new causes:
- hacking;
- new waterproofing;
- new pipes;
- new wiring;
- drilling;
- altered walls;
- new windows;
- new air-conditioning systems.
Once that work exists, a later defect may sit at the boundary between original construction and owner-created work.
The fourth article in this batch owns that boundary.
Why the DLP Cannot Last Forever
A completed home enters use.
Things wear.
Households alter spaces.
Fixtures age.
Maintenance quality differs.
If every later problem remained presumed to be an original construction defect indefinitely, cause and responsibility would become impossible to manage fairly.
The DLP creates a defined early window in which original defects can be identified while the construction state is still relatively fresh.
The Owner Should Leave the DLP With a Maintenance Baseline
By the end of the first year, a careful owner should know the flat.
- Which doors tend to move?
- Where does water collect?
- Are windows operating correctly?
- Are there recurring cracks?
- Do sanitary fittings leak?
- Are there unusual sounds or smells?
- Has renovation altered any critical system?
The end of DLP should not feel like protection disappearing.
It should feel like the homeowner taking over a home whose baseline condition is understood.
Failure Mode: Waiting Eleven Months to Inspect the Flat Properly
The legal window may still be open.
The evidential window may be much worse.
Furniture, renovation, use and ordinary wear may already have changed the flat substantially.
HDB’s advice to report within one month exists because early inspection is easier to interpret.
Failure Mode: Assuming Every Hairline Crack Is a Major Defect
Buildings move and materials shrink.
Some surface imperfections are cosmetic.
Others can indicate a problem requiring investigation.
The point of the joint inspection is not to classify every mark as catastrophic.
It is to determine the actual condition and appropriate rectification.
Failure Mode: Renovating Over a Known Defect
A contractor says the defect can be covered by carpentry or new tiles.
That may hide the symptom while making future access harder.
Known construction defects should be resolved first wherever possible.
The Better DLP Exit Sequence
- Inspect early after key collection.
- Report suspected defects before renovation.
- Attend the joint inspection.
- Complete and verify rectification.
- Begin renovation only with the original state clearly understood.
- Monitor the flat through the first year.
- Report genuine outstanding DLP items before expiry.
- After expiry, move into ordinary homeowner maintenance unless another owner—such as Town Council—applies.
Forward Play: Follow One New Flat
Keys are collected.
The owner inspects before renovation.
Defects are reported and rectified.
Renovation begins.
The household moves in.
The owner watches the flat through changing weather and ordinary use.
At the end of the year, the construction-defect window closes.
The home continues.
Maintenance responsibility has shifted from a temporary handover state into long-term ownership.
Reverse Play: Start From a Ten-Year-Old Flat
A tap fails.
A door hinge wears.
A seal deteriorates.
No one asks whether the original building contractor should still be responsible for every item.
Work backwards and the need for a defined handover period becomes obvious.
The Deeper Housing Principle
A home changes state after construction.
At first, the dominant question is whether it was delivered correctly.
Later, the dominant question is whether it is being maintained correctly.
The DLP is the bridge between those two responsibilities.
The Deepest Answer
The HDB Defects Liability Period ends because a completed flat cannot remain forever in a construction-handover state.
The first year gives owners a structured window to identify original defects while the evidence is fresh.
HDB and the Building Service Centre help verify and rectify those items.
Then the home becomes what it was always meant to become:
A LONG-LIVED ASSET WHOSE CONDITION NOW DEPENDS INCREASINGLY ON THE OWNER, THE NEIGHBOURS AND THE COMMON-PROPERTY SYSTEM AROUND IT.
