HDB Renovation: the red flags in reno contracts
HDB Renovation contracts in Singapore are supposed to protect you, but a badly written one can leave you exposed the moment something goes wrong. Knowing the warning signs before you sign is the difference between a smooth project and a stressful one. Here are the red flags that should make you pause and push for changes.
1. No proof of licence or DRC registration
The biggest red flag is also the most basic. HDB only allows renovation by a BCA-licensed contractor on the HDB Directory of Renovation Contractors, and the contract should reflect that.
- If the firm cannot show a valid DRC registration, walk away.
- Watch for vague claims like "our partner is licensed" with no name or number in writing.
- Unlicensed work risks HDB ordering it removed at your cost, plus a failed end inspection.
A proper contract names the licensed entity clearly. Anything less is a gamble you should not take.
2. Vague or missing scope of works

A contract that does not spell out exactly what gets done is an open invitation for disputes.
- Beware lines like "full renovation" or "as agreed" with no item list attached.
- Look for the specific rooms, materials, quantities, and finishes in a schedule.
- If hacking, plumbing, electrical, tiling, and carpentry are not listed, they may not be included.
From 1 Oct 2024 the CaseTrust Renovation Framework (RFPS) applies to contracts of S$5,000 and above and favours "Open Book" itemised pricing, so a solid contract should show real detail, not hand-waving.
3. No clear payment schedule or deposit terms
How money moves is where leverage lives. A contract that is loose here puts you at risk.
- Red flag: a demand for a large upfront payment with no stage milestones.
- Red flag: no mention of the HDB renovation deposit, which is S$500 for flats up to 3 rooms and S$1,000 for 4 rooms and larger, refunded only after a compliant end inspection.
- Red flag: no clause on what happens to payments if a stage fails or is done poorly.
You want progress payments tied to completed, inspected work, with the deposit handled transparently.
4. Unrealistic timeline with no noise-rule acknowledgement
Any contract that promises a finish date without respecting HDB's rules is either naive or careless.
- Noisy works like hacking and drilling are only allowed 9am to 5pm on weekdays and Saturdays, never on Sundays or public holidays.
- The renovation permit must be applied for within 3 months of key collection for a new flat, the permit lasts 3 months, and HDB inspects at the end.
- A timeline that ignores these limits will slip, and the blame game starts.
A good contract builds the rules into the schedule so both sides know the real working days.
5. No warranty or defect-handling clause
Defects surface after you move in, not on handover day, so the after-sales promise must be on paper.
- Red flag: no written warranty period for workmanship or carpentry.
- Red flag: no stated response time for fixing leaks, doors, or peeling surfaces.
- Red flag: no process for variation orders, so changes become arguments over price.
Insist on a clear warranty length and a simple way to log defects with your site diary and photos as backup.
6. Clauses that shift risk onto you
Some contracts quietly move every risk your way. Read the fine print for these traps.
- A clause saying you accept all works "as is" at handover, with no snagging window.
- Language that lets the contractor substitute materials without telling you.
- No mention of who pays if HDB rejects a non-compliant item, like a shifted toilet or hacked parapet wall.
Structural limits are fixed: no hacking of structural walls or beams, toilets cannot be shifted, and parapet walls, floor traps, corridor windows, and the main door position are restricted. The contract should honour all of that.
Spotting these red flags early lets you fix the contract or walk away cleanly. And if you are planning whole-house customization, where one supplier handles your kitchen, wardrobes, and living room carpentry under a single clear agreement, getting the contract right from the start keeps the whole home consistent and the warranty under one roof.
