HDB Renovation Debris, Lift and Corridor Rules: What Homeowners Must Know

Hacking out old tiles and carpentry fills a lot of bags very quickly. Where that debris goes, and how the lift lobby and corridor look at the end of each day, is one of the things neighbours notice most during an HDB renovation.

HDB's general terms and conditions for renovation make the flat owner responsible for the works in the flat, including how the contractor handles debris. This guide sums up what those rules say. It is general information, so check the latest requirements with HDB and your Town Council before work starts.

You are responsible, not just your contractor

HDB's important information on renovations says you are responsible for the renovation in your flat and must make sure your contractor's work follows HDB's guidelines. You must also engage a contractor from HDB's Directory of Renovation Contractors, and HDB and the Town Council reserve the right to control and give directions while the work goes on.

In practice, that means a complaint about debris in the corridor or a choked chute comes back to you as the owner, so it is worth agreeing the debris plan with your contractor before the first day of hacking.

Where renovation debris can go

HDB's terms set out two situations:

• If your Town Council provides debris removal: the debris must be packed and placed neatly at the Town Council's designated sites, or as your Town Council instructs, so that it causes no obstruction. HDB says you are to pay for the haulage and debris removal services the Town Council provides, where applicable.

• If your Town Council does not provide it: your contractor must remove the debris and dispose of it at a site approved by the National Environment Agency (NEA).

Ask your Town Council which applies to your block before you start, and write the answer into your agreement with your contractor.

Skip tanks in common areas and car parks

A skip tank can make a big hacking job much tidier, but it needs permission. HDB says you should approach your Town Council for approval to place a skip tank in a common area. For HDB car parks or lots, you need a permit from HDB, which you can ask for in writing or at your HDB Branch by appointment. HDB warns that placing a skip tank in an HDB car park without a valid permit is an offence, and repeat offenders may face court action and fines.

What must never go down the chute or drain

HDB's terms are clear on this:

• No debris down the refuse chute, the WC pan or the floor trap. Any choke or damage that results has to be cleared and repaired at your expense.

• No waste water, terrazzo slime or building debris discharged into the sewage system, onto the staircase or passageway, or into the pneumatic waste conveyance system (PWCS) in estates that have one.

Tile cutting and grinding slurry is the usual culprit, so ask your contractor how they will collect and remove it.

Keeping corridors, staircases and lifts usable

The joint guidelines on the use of common areas in HDB estates from Town Councils, SCDF and the National Fire and Civil Emergency Preparedness Council show what a safe corridor looks like:

• Keep at least 1.2m of clear width in the corridor. That is the space an ambulance crew or a wheelchair user needs.

• Keep staircases and landings clear at all times, because they are the escape route.

• Do not store items in dry or wet riser compartments or hose reel compartments, and avoid piling up combustible materials.

During a renovation, that means bags of debris, boxes of tiles and spare boards should not sit in the corridor or on the staircase landing. For lifts, ask your Town Council what it expects, such as protective covering or advance notice for bulky deliveries, and make sure your contractor follows it.

Be a good neighbour

• Display the Notice of Renovation outside your flat from the time you get your permit until all the work is done, as HDB requires.

• Keep noisy works within HDB's hours. Our HDB renovation hours and neighbour notice guide explains the times and the 5-day notice.

• Check whether your works need a permit first. See our HDB renovation permit guide.

• If you are taking down a wall, plan for more debris than usual. Our HDB bedroom wall removal guide covers what HDB allows.

• At the end of the job, walk the corridor, lift lobby and staircase with your contractor as part of your renovation handover checklist.
