The day your condo developer hands over the keys is the single most important inspection day in the 25-year life of your home. It is also, for most buyers, the least rehearsed. This 2026 guide walks through exactly what the Temporary Occupation Permit (TOP) legally means, how the Defects Liability Period (DLP) works under the Housing Developers (Control and Licensing) Act, what a professional defects inspection looks like room-by-room, and how to escalate if a defect is not rectified within the statutory window.

What TOP actually means — and does not mean

A Temporary Occupation Permit is issued by the BCA under the Building Control Act when the development has met minimum safety, structural and sanitary standards and is fit for temporary occupation. In plain English: the building is safe to live in, but regulatory sign-off is still in progress.

TOP is followed some months later by the Certificate of Statutory Completion (CSC), which is the final regulatory approval once all architectural, M&E, landscape and external works are closed out.

For the buyer, TOP triggers three commercial events under the standard-form SPA:

The Defects Liability Period in detail

Under Schedule 2 of the Housing Developers Rules (the standard SPA clauses prescribed by the Controller of Housing), the developer is required to make good, at their own cost, any defect, shrinkage or fault in the Building Unit caused by defective workmanship or materials or by the unit not being constructed in accordance with the approved plans. The obligation runs for 12 months from the date of Notice of Vacant Possession.

Key practical points:

• Notify the developer in writing (email counts) of any defect within the DLP. Verbal notifications are unenforceable.
• If the developer does not commence rectification within one month of written notice, you may engage your own contractor to rectify and deduct the cost from the developer — provided you give 14 days’ written notice of intention first.
• The DLP does not cover wear-and-tear, misuse, or alterations you have made to the unit.
• Major structural defects (beams, columns, slab) have a separate 15-year limitation period under the Building Control Act.

Inspection day — a room-by-room walk-through

Give yourself two hours minimum. Take: a spirit level, a measuring tape, a torch, a power-point tester (available for around S$15), a roll of masking tape, a marker, a sheet of printer paper, and a smartphone with a full battery. Many buyers also engage a professional defect inspector for a fee of around S$400-800 per unit depending on size — a worthwhile investment on a S$1.5m-plus purchase.

Living / dining

• Walk the entire floor. Tap tiles with a coin — a hollow sound indicates a poor screed bond.
• Run a marble or spirit level across the floor; a fall of more than 3 mm over 2 m should be flagged.
• Check ceiling for hairline cracks, particularly at beam/slab junctions.
• Open and close every sliding door 3-5 times — listen for grinding, sticky runners, mis-aligned handles.
• Check air-conditioning: run each fan coil unit for 10 minutes on cool and on dry, listen for gurgling, check drip-tray drainage.

Bedrooms

• Open every wardrobe door, test soft-close hinges, check shelf alignment.
• Check skirting along all walls — gaps more than 2 mm are defects.
• Test every power-point with the tester (live / neutral / earth indicator).
• Close the door fully — check for light gaps around frame, check door-closer speed.
• Check window seals by spraying a fine mist on the outside (many buyers do this during the first rain).

Kitchen

• Turn every tap fully open for 60 seconds; test mixer hot/cold blend; check for slow drainage.
• Run dishwasher cycle (if provided), oven at 200°C for 15 minutes, hob on high.
• Open every cabinet and drawer; test soft-close; check that runners do not bind.
• Check for silicone gaps at counter-splashback junction — should be continuous and flush.
• Test extractor hood fan on all settings; confirm exhaust flap opens.

Bathrooms

• Shower test: run at full flow for 5 minutes, verify floor drainage (no ponding beyond 24 hours is the industry benchmark).
• Flush toilet 5 times; check cistern refill timing and seat alignment.
• Check mirror-cabinet doors, shelves; test backlit LED strip if provided.
• Tap every tile with a coin; flag hollow sounds.
• Run hot water for 2 minutes at both basin and shower; check instant-heater / storage heater cycling.

Balcony / yard

• Check tile falls toward drains; no ponding.
• Verify balcony screen glass is fully seated; safety tape or sticker removed.
• Yard tap should run at full pressure; washing machine standpipe drains cleanly.

M&E and overall

• Test the main DB (distribution board): flip each MCB individually and identify which circuit it protects.
• Test the audio/video intercom to guardhouse.
• Test smart-home panel if provided; check Wi-Fi signal in every room.
• Check the unit handover pack: as-built drawings, appliance warranties, maintenance schedules, keys count.

How to log defects properly

Most developers now run a defect-management portal or a QR-code driven mobile form. If yours does, use it — it creates an auditable log with timestamps. If not, draft a signed Defect List, sign two copies, and ask the handover officer to counter-sign with a date. Each defect entry should include:

Worked example — the timeline of a typical handover

Common defects ranked by frequency

1. Wall / ceiling hairline cracks (shrinkage-related, usually stabilises after 6 months).
2. Floor-tile hollowness.
3. Door alignment and soft-close.
4. Silicone gaps at wet-area junctions.
5. Paint drips, roller marks, colour mismatches on patches.
6. Cabinetry: gaps, mis-alignment, scratched laminate.
7. Aircon: noisy fans, poor drainage, low cooling.
8. Electrical: non-functional points, wrong polarity, missing cover plates.
9. Plumbing: leaks under basins, slow drainage, inconsistent water pressure.
10. Balcony ponding.

If the developer does not rectify — escalation path

1. Serve a formal 14-day notice citing the standard-form SPA clause, threatening to engage your own contractor and deduct costs.
2. Report to the Controller of Housing (BCA): the Housing Developers (Control and Licensing) Act empowers the Controller to take administrative action against developers in breach. Use the BCA feedback portal.
3. Consumers Association of Singapore (CASE): CASE mediates consumer disputes and can help facilitate settlement, particularly for finishes-quality issues.
4. Strata Titles Board (STB): for disputes that involve common property or the Building Maintenance and Strata Management Act.
5. Small Claims Tribunal: for money claims up to S$20,000 (S$30,000 with parties’ consent).
6. High Court civil action: for larger, structural, or complex disputes — typically after engaging a surveyor or architect to prepare a quantified report.

Frequently asked questions

When does the Defects Liability Period start?

From the date of the developer’s Notice of Vacant Possession. The statutory 12-month period is prescribed in Schedule 2 of the Housing Developers Rules.

Do I need to be physically present at handover?

Yes. Your identity documents and the original keys-collection letter must be presented. If you cannot attend, grant a notarised Power of Attorney to a trusted representative.

Can I engage a professional defect inspector?

Yes. Independent defect-inspection firms typically charge S$400-800 per unit depending on size. They bring calibrated instruments (moisture meters, infra-red cameras, spirit levels) and a standardised report, which strengthens your claim if disputes arise.

What if I only discover a defect after moving in?

Report it within the 12-month DLP in writing. The developer remains liable for any defect arising from defective workmanship, materials, or non-compliance with approved plans during this period.

What about major structural defects?

The Building Control Act imposes a 15-year limitation period for structural defects. Structural claims are rare but serious — engage a Professional Engineer to inspect if you suspect one.

Does the DLP cover wear-and-tear?

No. Normal use, wear-and-tear, and any alterations you have made to the unit are excluded.

Can the developer refuse to rectify on grounds of “cosmetic issue”?

Only if the “defect” is genuinely cosmetic wear. Shrinkage cracks, paint drips, silicone gaps and poor workmanship are rectifiable defects under the SPA, not cosmetic issues. If the developer refuses, escalate to BCA.

What counts as a defect — is a small hairline crack a defect?

Shrinkage cracks up to 0.3 mm wide are generally considered within industry tolerance for a plastered wall, but wider cracks or any crack on a tile, ceiling or beam is a defect. Photograph, measure with a crack gauge, and log.

Who is the “Managing Agent” and when do I start paying?

The Managing Agent is the professional property-management firm appointed by the developer to run the MCST (Management Corporation Strata Title) until the first AGM, after which the MCST Council may retain or change the agent. Maintenance charges run from NVP.

What if I find a defect on the last day of DLP?

Notify in writing immediately. As long as the defect was reported within the 12-month window, the developer remains liable to rectify even if rectification work itself extends beyond the DLP end-date.

Can I claim compensation for delayed handover?

Yes. The standard SPA provides for Liquidated Damages if the developer fails to deliver vacant possession by the contracted date (typically 3 years from the date of the Sale & Purchase Agreement). LD is calculated at 10% per annum (on purchase price) for each day of delay, pro-rated.

What happens at the end of the DLP?

The Managing Agent typically schedules a formal “end-of-DLP” inspection of common property (lobbies, lifts, facilities). For your own unit, you bear responsibility for any new defects after DLP end-date, except for latent defects discovered within the 15-year structural window.
