The drilling starts just as your baby falls asleep, or the hacking carries on while you are trying to finish a work call. Renovation noise is part of life in an HDB block, especially when a new owner collects their keys or a flat changes hands. The good news is that HDB renovation noise hours are not a free for all. HDB sets clear windows for general and noisy works, and there is a proper route to raise it when a contractor ignores them.
This guide is for HDB residents living beside a renovation. If you live in a condo, the rules come from your MCST (Management Corporation Strata Title, the body that runs a condo estate) instead, and our guide to renovating a condo unit under MCST rules covers that side.
HDB Renovation Noise Hours at a Glance
HDB regulates when renovation work can happen in its flats, and it separates ordinary works from noisy ones. In broad terms, the rules as commonly published by HDB are:
- General renovation works are allowed during the daytime on weekdays and Saturdays.
- Noisy works, such as hacking walls or floors, drilling, and other works that create loud noise, are restricted to a shorter daytime window on weekdays only.
- No renovation work is allowed on Sundays and public holidays.
HDB updates its renovation guidelines from time to time, and it has adjusted the noisy works window in the past. Always check the current hours on the HDB website before you raise a complaint, so that you are quoting the rule that actually applies.
| Type of work | Weekdays | Saturdays | Sundays and public holidays |
|---|---|---|---|
| General works (painting, carpentry install, tiling with minimal noise) | Allowed within HDB’s daytime hours | Allowed within HDB’s daytime hours | Not allowed |
| Noisy works (hacking, drilling, chiselling, grinding) | Allowed within HDB’s shorter noisy works window | Not allowed | Not allowed |
| Quiet tasks by the owner (assembling furniture, hanging pictures) | Generally treated as normal household activity | Generally treated as normal household activity | Be considerate, especially early and late |
The key point most residents miss: a contractor drilling on a Saturday afternoon is usually breaching the rules, even if painting at the same time would be fine.
What a Proper Renovation Should Look Like
Knowing what is expected helps you judge whether your neighbour’s job is being run properly or cutting corners.
- Permits for regulated works. Some works, such as hacking walls, changing floor finishes in certain areas, or installing a bathtub, need an HDB permit. Many contractors handle this for the owner. Our guide to HDB renovation rules and permits explains which works need approval.
- Registered contractors. HDB keeps a Directory of Renovation Contractors (DRC), and owners are expected to use a contractor listed on it for HDB works. You can search the DRC list on the HDB website if you want to confirm your neighbour’s contractor is registered.
- A renovation notice for neighbours. It is common practice, and expected under HDB’s guidelines, for the contractor to put up a notice at the unit or lift lobby showing the renovation period and contact details. Some owners also leave a friendly note or small gift for neighbours before work starts.
- Protection of common areas. Lift interiors and corridors are often covered with protective boards, and debris should be bagged and removed, not left in the corridor.
If you cannot find a notice, it does not automatically mean the work is illegal, but it is worth asking the contractor or owner for the details.
Step One: Talk to the Owner or Contractor First
Most renovation noise problems are solved with a polite conversation. Owners often do not know exactly what their contractor is doing on site, especially if they are still living elsewhere.
- Note the details before you knock. Write down the date, time and type of noise (hacking, drilling, grinding). A short phone video with the time showing can help later.
- Use the contact on the notice. The renovation notice usually lists the contractor’s name and phone number. Calling the contractor directly is often the fastest fix if workers are drilling outside the noisy works window.
- Mention your specific situation. A newborn, a night shift worker, or someone recovering from surgery is a good reason to ask for a heads up before the loudest days. Many contractors will tell you which days will be worst.
- Keep it calm. You will be neighbours for years. A friendly request works far better than a note taped to the door.
If the noise is within the permitted hours, there is not much you can demand. Asking for advance warning of the loudest days, or for workers to start a little later on a particular day, is reasonable. Insisting that legal work stops is not.
Step Two: Report Breaches to HDB
If works continue outside the permitted hours after you have spoken up, or if you cannot reach anyone, you can report it.
- HDB is the main authority for renovation rules in HDB flats. You can give feedback through HDB’s official website or the HDB e-services channels, or contact your HDB Branch, which serves your town.
- The OneService app, run by the Municipal Services Office, lets you report municipal issues and routes them to the right agency. It is a convenient way to log a case with photos and a location.
- Give specifics. Include the block and unit number (for example, write it as unit 05-12 in your message), the dates and times, the type of work, and any photos or videos. Vague reports are harder to act on.
HDB can follow up with the owner and the contractor, and contractors who repeatedly breach the rules can face action under HDB’s renovation framework. The exact penalties and procedures are set by HDB and can change, so check the HDB website if you want the current details.

When the Noise Is Not Really Renovation
Sometimes the problem is not a contractor at all. An owner may be drilling at 10pm on a Sunday to put up shelves, or the noise may be ongoing household activity like dragging furniture or banging.
- Owner DIY outside hours. Hanging a picture is ordinary living. Hours of drilling on a Sunday night is not, and you can still raise it with the owner first, then HDB if it continues.
- Persistent neighbour noise. If the noise is about daily behaviour rather than renovation, the approach is different. Mediation through the Community Mediation Centre and, as a last resort, the Community Disputes Resolution Tribunals are the usual routes. Our guide to dealing with noisy neighbours walks through these options.
- Damage to your flat. Hacking next door can occasionally cause cracks or leaks in a shared wall or ceiling. Take dated photos as soon as you notice anything, inform the owner and contractor, and contact HDB for advice on inspection.
Key Takeaways for HDB Residents
- HDB allows general works on weekdays and Saturdays within set daytime hours, restricts noisy works to a shorter weekday window, and bans renovation on Sundays and public holidays. Check HDB’s site for the current hours.
- Speak to the owner or the contractor on the renovation notice first. Many issues end there.
- If breaches continue, report to HDB or through the OneService app with specific dates, times and evidence.
- For noise that is not renovation, use mediation routes rather than HDB’s renovation rules.
A renovation next door rarely lasts more than a couple of months. Knowing the rules lets you push back when a contractor breaks them, and relax a little when they are simply doing their job.
