Condo Defects in Singapore: DLP, Hidden Defects and Who Pays Years Later?

[ Updated 1st Nov. 2026 -Changes effective 31 December 2026 ]

You collect your condo keys, inspect the rooms and discover a hollow tile, a leaking tap or a window that will not close properly. Reporting these problems seems straightforward.

But what happens when water seepage appears months later? When repairs fail repeatedly? Or when defects affect the façade, basement or swimming pool rather than your apartment?

Understanding condo defects in Singapore requires more than knowing that the Defects Liability Period lasts 12 months. Owners also need to understand when that period starts, how to report defects properly and what happens when problems emerge after it ends.

With new Housing Developers Rules taking effect on 31 December 2026, buyers must also distinguish between existing contractual terms and the forthcoming safeguards.

In this guide, we explain how to protect your position from purchase to key collection—and beyond.

1. What Does the Condo Defects Liability Period Cover?

The Defects Liability Period, commonly called the DLP, is the contractual period during which the developer must rectify qualifying defects at its own expense.

Under the prescribed Sale and Purchase Agreement, defects can include faults arising from defective workmanship or materials, or construction that does not comply with the agreed specifications. The provisions can cover the apartment, the housing project and common or applicable limited common property.

Typical inspection items include:

• Water seepage around windows, walls or ceilings.
• Cracked, loose or uneven tiles.
• Faulty doors, windows and supplied fittings.
• Plumbing leaks and drainage problems.
• Electrical fittings that do not function properly.
• Finishes or installed items that differ from the contractual specifications.

An inspection finding does not automatically establish developer liability. The cause matters: damage caused by renovation works, misuse or subsequent alterations may involve a different responsible party.

We recommend inspecting before renovation begins. Once contractors start hacking, installing carpentry or modifying plumbing, identifying the original cause of damage can become harder.

2. When Does the 12-Month DLP Start?

Do not assume that your DLP begins on the day you choose to collect your keys.

Under the existing prescribed agreement, the start date is generally the earlier of:

• Actual delivery of vacant possession; or
• The 15th day after receipt of the prescribed TOP-stage documents.

Check the wording of your own agreement and the relevant notices rather than calculating the deadline from memory.

The forthcoming 35-day arrangement

For applicable projects under the new rules, the DLP and maintenance-charge liability start on the earlier of actual vacant possession or day 35 after receipt of the TOP payment notice. The individual-unit DLP remains 12 months.

The practical step is simple: ask your solicitor or developer to confirm the applicable start date and expiry date in writing, then record both.

3. Which Projects Come Under the New Rules?

The new prescribed contracts are mandatory for projects with no OTP issued before 31 December 2026. Earlier projects may retain existing prescribed forms for unsold units. Corresponding changes also cover EC projects.

This means a purchase made in 2027 does not, by itself, establish that the new terms apply.

Before signing, ask:

• Which prescribed agreement applies to this project?
• What event starts my DLP?
• What provisions cover common-property defects?

For existing owners, the announcement is a reason to review your contractual position—not to assume your current DLP has been extended.

4. Inspect More Than Once: Five Useful Checkpoints

A single inspection cannot reveal how a home performs after months of use and heavy rain.

We recommend treating defects inspection as a process.

A professional inspector may use moisture meters, thermal imaging or other diagnostic tools where appropriate. These tools support an investigation; they do not replace a clear written report explaining the findings and limitations.

For owners inspecting independently, work systematically through each room. Test accessible fittings, photograph findings and record the exact location of every issue.

Allow time before the DLP expires to investigate and report problems.

5. How to Report Condo Defects Properly

A verbal conversation with the site team is useful, but a written record is much easier to follow up.

Your defect report should identify:

• The unit and affected room or area.
• The precise location of the problem.
• What you observed and when.
• Clear photographs or videos.
• Whether the defect has been repaired previously.
• Any relevant defect reference number.

For recurring seepage, record the circumstances. Does it happen during heavy rain, after the upstairs bathroom is used or when the air-conditioning runs?

These details can help distinguish the symptom from its underlying cause.

Keep copies of submissions, acknowledgements, inspection appointments and repair records. If the developer uses an online portal, retain your own copies of important entries and attachments.

The rectification process: one month, then a further notice

Under the prescribed agreement, the developer generally has one month after receiving notice to make good the defect.

If it fails to do so, the purchaser may issue a further written notice setting out the proposed rectification cost and the intention to appoint their own contractor if the developer does not act within another 14 days.

The agreement provides a mechanism for arranging rectification and recovering qualifying costs. Follow your agreement’s notice requirements carefully. Before commissioning substantial disputed works or attempting to deduct money, obtain advice on the procedure and evidence required.

After repairs, inspect again. A painted-over stain does not necessarily establish that the source of a leak has been resolved.

6. What Happens If a Defect Is Still Unresolved When the DLP Ends?

The expiry date does not erase an outstanding defect report.

BCA states that a defect reported during the DLP remains the developer’s responsibility if it is still unresolved beyond that period.

This makes your records especially important.

Maintain a defect log showing the original report date, repair attempts, photographs and current status. Where a problem returns, link the new report to the earlier complaint rather than treating every recurrence as an unrelated issue.

If the developer says repairs are complete but you disagree, explain what remains wrong and support your position with evidence.

7. Who Handles Common-Property Defects?

A problem visible inside your apartment may originate outside it.

For example, damp walls may involve the façade, roof or another shared building element. Identifying the source is essential before deciding who should investigate, arrange repairs or bear the cost.

For suspected common-property issues, notify the managing agent or MCST alongside any relevant developer report. Where several units experience similar symptoms, coordinated investigation may be more effective than separate repairs.

Additional protection under the new rules

For applicable projects, common-property DLP protection runs until the later of 12 months from the applicable start date or six months after the first AGM. It is not an automatic 18-month period.

For management councils, we recommend an early handover review covering:

• Outstanding developer defect reports.
• Recurring complaints across different units.
• Previous investigations and repair attempts.
• Inspection findings for shared facilities.
• Relevant contractual deadlines.

Distinguish the immediate need to investigate or make an area safe from the separate question of recovering costs from a responsible party.

8. What If a Hidden Defect Appears Years Later?

Singapore has introduced stronger regulatory consequences for housing developers responsible for serious construction-quality failures.

Effective 22 May 2026, new frameworks allow authorities to impose sanctions on developers responsible for severe safety-related regulatory non-compliance or qualifying major defects.

Depending on the circumstances, errant developers may face:

• Land sales disqualification: Exclusion from eligible Government land sales for sites with residential components for up to five years.
• Sales suspension: Restrictions on selling units in future unlaunched housing projects, potentially lasting up to five years.
• Extended accountability: Certain directors, substantial shareholders and related parties may also fall within the scope of the frameworks.

Authorities consider factors such as the severity and number of defects, how quickly the developer addresses them, their impact on residents, and any aggravating or mitigating circumstances.

These measures are intended to deter serious or repeated failures, not to penalise developers automatically for every minor defect.

For homeowners, the distinction is important: the new rules strengthen accountability, but they do not extend the standard 12-month DLP or guarantee compensation for individual owners.

Prospective buyers can also use BCA's Quality Housing Portal to compare developers' and builders' construction-quality track records before committing to a property.A latent defect is a hidden problem that may only become apparent over time.

Waterproofing failures, concealed construction problems or recurring building-wide issues may require specialist investigation to establish their origin.

The end of the DLP does not automatically rule out every legal claim. However, a later claim requires an appropriate legal basis, evidence of responsibility and compliance with applicable time limits.

Singapore’s Limitation Act generally provides six-year periods for certain contract and tort claims. For qualifying claims involving latent damage, Section 24A may allow a later knowledge-based period, subject to statutory conditions and the overriding 15-year limit under Section 24B. These are legal limitation rules, not a 15-year developer warranty.

Owners should therefore avoid assuming that a recently discovered problem automatically gives them several more years to act.

For serious or recurring defects:

1. Document the damage and when it was first observed.
2. Preserve previous reports and repair records.
3. Obtain appropriate technical advice on the cause.
4. Seek legal advice promptly where responsibility or recovery is disputed.

9. Check Construction Quality Before Buying

Defects due diligence should begin before key collection.

For a new launch, investigate the developer’s completed projects and available construction-quality information. For a resale condo, examine the actual building’s condition and maintenance history.

Useful questions include:

• Have residents reported recurring water ingress?
• Are major rectification works planned or underway?
• Have previous repairs resolved the underlying problems?
• Are relevant inspection reports or management records available?
• Could substantial shared repairs affect future ownership costs?

A well-presented showflat or freshly repainted apartment cannot answer all these questions.

More information before buyers commit

The forthcoming rules also require developer CONQUAS track-record disclosure, clearer plans and maximum maintenance-charge disclosure. They strengthen safeguards around plan changes, including conditional reimbursement of specified expenses, capped at 5% of the purchase price, when substantive changes lead to developer annulment following buyer objections.

Before booking, alongside their signed agreement.

10. Stronger Developer Sanctions Already Apply

The forthcoming contractual changes are separate from the regulatory measures effective since 22 May 2026.

Under those frameworks, severe safety-related non-compliance or qualifying major defects can lead to land-sales disqualification or sales suspension for up to 5 years. Relevant directors, substantial shareholders and other parties may also fall within scope.

Authorities consider matters such as severity, resident impact and the developer’s response. These sanctions do not automatically compensate individual owners or resolve a private defect claim.

For buyers, regulatory accountability adds protection. Careful inspections, clear reporting and timely follow-up remain essential.

Frequently Asked Questions

Does every condo owner get the new 35-day DLP start arrangement?

No. Check which contractual framework applies to the project. Buying after the commencement date does not automatically mean an earlier-launched project uses the new prescribed agreement.

Is the individual-unit DLP being extended?

The individual-unit period remains 12 months. The forthcoming changes concern its commencement arrangements and additional common-property protection.

Can I report defects after moving in?

Report qualifying defects as soon as they become apparent during your applicable DLP. Occupation may reveal problems that were not visible during the initial inspection.

Should I hire a professional defects inspector?

Consider the complexity of the property, your confidence in inspecting it and the seriousness of any suspected problems. Ask what the service includes, how findings are documented and whether follow-up inspection is available.

Does an unresolved defect disappear from the developer’s responsibility after the deadline?

BCA’s guidance states that defects reported during the DLP remain the developer’s responsibility if unresolved after it ends. Keep evidence of the original report and subsequent repair history.

Does the DLP restart when I buy a resale condo?

Do not assume that a resale purchase creates a fresh developer DLP. Ask your solicitor to establish any remaining contractual rights and how they apply to your purchase.

Protect Your Home Before Small Defects Become Bigger Disputes

We recommend keeping five habits throughout your ownership journey:

• Before buying: investigate construction quality and building history.
• At key collection: inspect before renovation.
• When reporting: keep dated, specific written records.
• After repairs: check that the problem has been resolved.
• Before deadlines: review outstanding issues and act promptly.

The new safeguards improve buyer protection, but owners still need to understand their agreement and document what happens in practice.
