If you've ever lived in an HDB flat during renovation season — the sound of hacking at 8:55am on a Saturday morning, the non-stop drilling that seems to go on for weeks, the dust creeping under your door — you know exactly why noise rules exist.
And if you're the one doing the renovation, you need to know these rules just as urgently. Because violating them doesn't just mean angry neighbours knocking on your door. It means official complaints, demerit points for your contractor, and fines of up to S$5,000 upon conviction.
This guide covers every HDB renovation noise rule in full — sourced directly from HDB's official guidelines and the Singapore government's OneService noise infosheet. Whether you're a homeowner about to start renovation or a neighbour trying to understand your rights, everything you need is here.
📌 Important Note: All rules cited in this article are sourced directly from HDB.gov.sg and the OneService Noise Regulations Infosheet (PDF) — official Singapore government sources. Rules are subject to change. Always verify with HDB for the latest information.
The Two Types of Renovation Work HDB Recognises
Not all renovation work is treated equally. HDB draws a clear line between general renovation and noisy renovation — and each has different permitted hours.
General renovation includes painting, carpentry installation, plumbing work, electrical wiring, vinyl laying, and similar works that produce moderate noise levels.
Noisy renovation — officially described as "demolishing of walls, removing wall/floor finishes, cutting of tiles and heavy and excessive drilling works" — is the kind of work that reverberates through concrete walls and can be heard several floors away. This category has stricter time restrictions.

Understanding this distinction is important because the penalties apply based on work type, not just clock time.
HDB Renovation Permitted Hours: The Official Rules
Here are the exact permitted timings directly from HDB's official guidelines:
General Renovation Works
Noisy Renovation Works (Hacking, Drilling, Tile Cutting)
*Major Public Holidays with eve restriction: New Year's Day, Chinese New Year, Deepavali, Hari Raya Puasa, and Christmas Day.
Source: HDB — Important Information: General Terms and Conditions
This is confirmed by the official OneService noise infosheet published by the Singapore government:
"General renovations should only be carried out between 9:00am and 6:00pm on weekdays and Saturdays. No renovations are allowed on Sundays and Public Holidays."
"Noisy renovations within the flat such as demolishing of walls, removing wall/floor finishes, cutting of tiles and heavy and excessive drilling works, etc. can only be carried out between 9:00am and 5:00pm on weekdays."
"Noisy renovations are not allowed on Saturdays, Sundays, Public Holidays and eve of major Public Holidays."

What About DIY Works?
If you're doing your own Do-It-Yourself work — hanging a shelf, assembling furniture, minor drilling — HDB has a separate guideline:
"If you plan to carry out DIY (Do-It-Yourself) works, do limit it between 7:00am and 10:30pm, and keep noise to a minimum."
And:
"Try not to carry out any Do-It-Yourself (DIY) works involving drilling and hammering from 10:30pm to 7:00am as these generate noise which may disturb your neighbours."
Source: HDB — Important Information
So while your renovation contractor is bound by the strict 9am–6pm / 9am–5pm rules, your own personal DIY activities have a wider window — but with the expectation that you keep noise to a minimum outside of standard hours. The quiet hours of 10:30pm to 7:00am should be respected as a hard boundary for any noise-generating activity.
The OneService infosheet reinforces this:
"Even though HDB does not regulate these works, flat owners should keep to the permitted renovation timings to avoid disturbing their neighbours."

The 3-Day Consecutive Rule for Power Tools
This is one of the least-known HDB rules — and one of the most relevant to renovation planning:
"At any given time, only 2 of the handheld power tools approved by HDB or their equivalent can be used."
"Renovation contractors cannot take more than 3 consecutive days to demolish walls and/or remove wall and/or floor finishes."
Source: HDB — Important Information
What this means in practice: if your contractor starts hacking on Monday, all hacking and floor/wall removal must be completed by Wednesday. They cannot stretch demolition work across the entire renovation period. This forces contractors to plan demolition efficiently — and limits the number of days your neighbours experience the worst noise.
At RCS, we schedule all demolition and hacking works in a concentrated block at the start of the project. This means the loudest phase is short and defined — your neighbours know exactly when it starts and when it ends.
Your Obligations as a Homeowner
Many homeowners assume that noise rules are their contractor's problem. They're not. HDB places legal responsibility squarely on the flat owner.
Before Renovation Starts
You (or your contractor) must:
"Inform your neighbours staying within a radius of 2 units at least 5 days in advance before renovations begin with written notice."
"Do remind your contractor to put up the Notice of Renovation outside your flat early and throughout the renovation period."
Source: HDB — Important Information
That's not a suggestion. It's a requirement. And "within a radius of 2 units" means the units on both sides, above, below, and diagonally adjacent — potentially 8 to 10 households.
During Renovation
"When possible, close the main door of your flat while works are ongoing, to help reduce noise disturbance to your neighbours and do remember to inform them in advance of any works that may generate noise."
Source: HDB — Important Information
A small gesture — but one that HDB explicitly recommends and that makes a genuine difference. Closing the front door during hacking and drilling reduces noise transmission through the common corridor significantly.
What Happens If You Break the Rules
The penalties are real. Under the Housing & Development (Renovation Control) Rules 2006:
Additionally, contractors who repeatedly violate rules accumulate demerit points. Enough demerit points can lead to suspension or removal from HDB's Directory of Renovation Contractors (DRC) — effectively banning them from doing HDB work.

If you as the homeowner fail to pay a composition sum for the offence, you will be prosecuted in Court.
For Neighbours: What You Can Do About Renovation Noise
If you're on the receiving end of renovation noise, here's what the government recommends:
Step 1: Talk to your neighbour first
"Reach out to your neighbours and seek their understanding to avoid specific days or timeslots (e.g. if you have an important meeting or interview scheduled)."
Step 2: Find alternatives during peak noise
"If your neighbour's renovation works cannot be rescheduled, you may consider returning to your office/school or visiting the nearby Community Centre or library to carry out your work or study."
Step 3: Seek mediation if needed
"If necessary, approach your grassroots leader or other neighbours to act as a mediator when speaking with your neighbour."

Step 4: If violations occur
If renovation work is happening outside permitted hours (before 9am, after 6pm, on Sundays, on public holidays), or if noisy works like hacking and drilling are happening on Saturdays — these are actual violations. You can:
-
Report to your Town Council — they manage estate-level enforcement
-
Report via the OneService app — Singapore's official platform for municipal feedback
-
Contact HDB directly — for serious or repeated violations
Keep a record. Note the date, time, type of noise, and duration. This documentation helps enforcement agencies take action.
A Quick Reference for Common Scenarios
"Can my contractor hack tiles on Saturday?"
No. Hacking is classified as noisy work. Noisy work is not allowed on Saturdays.
"Can my contractor paint on Saturday?"
Yes. Painting is general renovation work. General work is allowed on Saturdays from 9:00am to 6:00pm.
"Can my contractor do carpentry work on Saturday?"
Yes — as long as it doesn't involve heavy drilling. Light carpentry (assembly, installation) falls under general renovation. Permitted 9:00am to 6:00pm.
"Can drilling happen on Saturday?"
No. Heavy and excessive drilling is classified as noisy work and is not allowed on Saturdays.
"Can my contractor work on Chinese New Year eve?"
General work — no, because CNY eve is one of the five eves where noisy renovation is not allowed. General renovation rules apply on CNY eve as they would on any normal weekday (9am–6pm general works only), but all noisy works are prohibited.
"Can I drill a hole for a shelf on Sunday?"
Technically, HDB guidelines for DIY say you can do it between 7:00am and 10:30pm — but you should keep noise to a minimum and be considerate. A single drill hole is different from a full day of drilling.
"My neighbour's contractor is hacking at 7:30pm on a Tuesday. Is that allowed?"
No. Even general renovation must stop by 6:00pm. Hacking must stop by 5:00pm. Work at 7:30pm is a violation. Report it.
"My neighbour's renovation has been going on for months. Is that allowed?"
For resale flats, all approved work must be completed within 1 month of the permit date. For BTO flats, it's 3 months. If it genuinely seems to be exceeding these timelines, you can check with HDB.
How RCS Manages Noise for Our Projects
We take noise management seriously — not because we have to (though we do), but because maintaining good relationships between our clients and their neighbours is part of delivering a quality renovation.
Here's what we do on every project:
-
✅ Written notice to all neighbours within 2-unit radius — delivered at least 5 days before work starts, as required by HDB
-
✅ Notice of Renovation displayed at the front door — throughout the entire renovation period
-
✅ All hacking and demolition concentrated in a 2–3 day block — well within the 3-day consecutive limit. The noisiest phase is short and planned
-
✅ Strict adherence to permitted hours — our workers arrive at 9:00am, not before. All noisy works stop by 5:00pm. No Saturday hacking, no Sunday work, no public holiday work
-
✅ Front door closed during noisy works — as HDB recommends
-
✅ Dedicated project manager — your single point of contact if any noise concerns arise from neighbours
We've renovated enough HDB flats to know that a well-managed noise schedule is as important as the renovation itself. Your neighbours will live next to you for years after the contractor leaves. Starting that relationship with respect goes a long way.
