Under HDB’s renovation portal terms, noisy contractor works such as hacking walls, removing floor finishes, cutting tiles and heavy drilling are generally limited to 9 am to 5 pm on Mondays to Fridays. Those works are prohibited on Saturdays, Sundays, public holidays and the eves of major public holidays listed by HDB. Other contractor renovation works are generally allowed from 9 am to 6 pm on weekdays and Saturdays, subject to the actual permit and applicable conditions.
If you are renovating a Punggol flat, check the permit and current conditions before booking each trade. Tell nearby neighbours in writing at least five days before work starts, following HDB’s notice instructions. If you are affected by noise, check the notice, record the time and type of work, and raise the specific issue with the owner, contractor or the relevant HDB Branch.
Quick Read
- Separate noisy contractor work, other contractor work and ordinary DIY.

- Record specific times and observations when asking for help.
CHAPTER 1 OF 10
Classify the work before putting it on the calendar
Ask the contractor for a scope by room and task. Separate demolition, removal of wall or floor finishes, tile cutting and heavy drilling from work that falls in the other renovation category. The name of a package can hide several different activities. For example, a kitchen installation may involve both assembly and substantial drilling. Ask which activity will happen at each stage and which time window applies.
Use HDB’s renovation portal conditions and the permit for the flat. HDB distinguishes noisy works from other works and gives separate conditions for household DIY. If the contractor has a doubt about a particular task, confirm the classification with the appropriate HDB Branch before work. Do this early enough that the contractor can move the appointment if needed.
Turn a broad scope into times a household can use Create a line for each disruptive task with the room, expected day, time window and person responsible. Then add quieter preparation and follow-up separately. If a job moves to another day, mark which trade and activities are affected. Give the household a version that distinguishes work planned for a day from the time workers actually need access.
A neighbour planning a call from home or an afternoon rest may only need to know the approximate period for the heaviest work. Give the most accurate window you can confirm and update it if something changes. Tell the contractor who will respond if a worker arrives before the scheduled time. That is easier than trying to work out the programme at the corridor after the first drill starts.
Keep one current version of the schedule. Use it when discussing permission, giving notices and talking to trades. If an instruction from a subcontractor differs, check it with the responsible contractor and confirm the answer before work begins.
CHAPTER 2 OF 10
Read the weekday hours and the holiday restrictions
HDB’s portal terms set a 9 am to 5 pm weekday window for noisy renovation. They prohibit that work on weekends, public holidays and the eves of the major public holidays listed in the terms. Check the official calendar and the list before booking. A weekday can look available in an ordinary schedule while being excluded under the conditions.
The terms require noisy works to be completed within three consecutive days. Ask the contractor how it will comply and confirm with HDB if the schedule involves a break or a holiday. Do not use the three-day condition as permission to work through an excluded day. Put the actual permitted dates in the project plan.
Work through a Friday example Suppose a contractor plans to hack tiles on Friday and continue on Saturday morning. The Saturday portion cannot use the noisy-work window. Ask the contractor to replan within the applicable conditions and update the neighbour notice if needed. If part of the work has to move, check what it does to debris removal and the later trades waiting for access.
A household scheduling work near a public holiday should check each day rather than counting calendar days from the start. Identify the noisy tasks and leave time for inspection or a correction if the first plan changes. Tell the people who will receive the notice when the heaviest work is expected.
If your permit specifies conditions for the exact job, keep the written document with the calendar. Check any difference between the general table and the permit directly with HDB. A verbal agreement among contractor, owner and neighbour does not settle a regulatory question about the hours.
Check which eves the current terms list
HDB’s portal terms name the eves of New Year, Lunar New Year, Deepavali, Hari Raya Puasa and Christmas for the noisy-work restriction. Check the current terms and Singapore’s official holiday calendar for the date in question. If the proposed work is close to a listed eve or another holiday, write the date beside the task and confirm it before the contractor allocates workers.
A family planning work in late December can mark the public holiday, the listed eve and the weekend separately. Then ask the contractor to identify the earliest sequence that fits the noisy-work conditions. Check the permit end date as well as the weekly timetable. If the combination creates uncertainty, ask HDB what applies to the actual job.
For a change that only affects deliveries or preparation, ask the responsible contractor whether that activity is allowed and how to keep shared areas clear. Update the calendar in enough time for neighbours and other workers to respond. A proposed holiday plan should say which activity is actually taking place.
CHAPTER 3 OF 10
Know what Saturday, Sunday and DIY mean
Under the portal terms, other contractor renovation work generally has a 9 am to 6 pm window on weekdays and Saturdays. Contractor renovation is prohibited on Sundays and public holidays under those terms. Verify the category of work before putting it on a Saturday. A job described as fitting or assembly may include a noisy operation that needs its own permitted time.
HDB’s DIY guidance asks households to limit DIY activity to between 7 am and 10.30 pm and keep noise low. Use that guidance for genuine household DIY and check the separate requirements for substantial work. If the task raises a structural, electrical or other specialist question, ask the appropriate professional before doing it.
Separate three common examples A contractor finishing permitted work on a Saturday should confirm that the individual tasks fit the non-noisy category. A contractor intending to do heavy drilling should book it in the noisy weekday window. A resident planning a small DIY task should check HDB’s guidance and choose a considerate time. Ask HDB if the work is difficult to classify.
If you hear drilling from another flat, record the time, duration and nature of the sound. You may know the sound but be unsure whether it is contractor work or a resident’s short DIY task. Ask about the actual situation before making a conclusion. Use the renovation notice if one is displayed and keep your initial message specific.
A condo household should use its own management office’s approval terms. Work permitted for an HDB project may have different requirements at a nearby private development. If a contractor is coordinating both addresses, ask it to keep the schedules and approvals separate.
| Activity | General time window | Key restriction |
|---|---|---|
| Noisy contractor work | Weekdays 9 am to 5 pm | Excludes public holidays and listed major holiday eves |
| Other contractor renovation | Weekdays and Saturdays 9 am to 6 pm | No contractor renovation on Sundays and public holidays |
| Household DIY | HDB advises keeping it between 7 am and 10.30 pm and minimising noise | Confirm the actual classification of substantial work |
CHAPTER 4 OF 10
Use the permit and authorised contractor for the actual scope
HDB requires owners to engage contractors listed in its Directory of Renovation Contractors for flat renovation under the applicable rules. Check the company you are appointing and ask which permits or specialist credentials apply. A schedule does not establish that a type of work is permitted. Check the specific guidelines and permit position before the contractor starts.
Ask which parts of the job are covered by the permit and have the contractor show the approved description. If the quote changes from removal of a finish to work on a wall, or from replacement to work on an opening, ask it to stop and confirm the new requirements before proceeding. Keep the approved and proposed scope visible to whoever is supervising on site.
Put scope and timing on separate lines For each job, write who is authorised to carry it out, what may be done and when. Add any required notice, permit and access constraints. For a noisy job, record the expected dates and permitted times. For other trades, identify anything that may become noisy during a visit. This makes it clear which part needs rescheduling if the job changes.
If the contractor says no permit is required for a particular part, ask which HDB guidance supports that position. Follow the general hours and conditions even for work that does not need a separate renovation permit. Keep the contractor’s explanation and any HDB response together.
A new owner arranging several trades may have a renovation permit for one scope and a separate appointment for electrical or window work. Check the instructions for each. Use one coordination calendar and keep the respective records available, so a worker can check what is approved before changing an activity.
CHAPTER 5 OF 10
Give the written notice early enough to be useful
HDB instructs owners to inform neighbours within the stated radius of two units in writing at least five days before renovations begin. Check the current wording and the relevant units for your flat. Follow the conditions for displaying HDB’s Notice of Renovation near the flat throughout the work where applicable. Keep a copy of the notice and when it was given.
Give the expected start, broad duration and the days when the loudest work is planned. Include a way to reach the responsible person during work. If you are using a sample notice, fill in the details for your flat. A note that says “works this month” without the disruptive dates gives neighbours little to plan around.
Share the dates and the route for changes For example, a household may tell nearby neighbours that noisy tile removal is planned within a stated weekday window, with cabinet fitting expected later. If a delivery or site finding moves the louder work, send an update when a new permitted window is confirmed. Tell the contractor about any practical coordination already agreed with neighbours.
Ask neighbours whether there is a specific time they would like you to avoid, then check whether the project can accommodate it within the permitted schedule. An owner can decide with the contractor which changes are realistic. Communicate what was actually agreed and avoid promising a complete day of silence if other work is still planned.
Retain the written notice and any revised schedule. If a neighbour contacts you about a different day, compare the actual work and times with those records. Confirm what was observed and update the responsible contractor if the team is doing a different task from the one planned.
Write a notice that helps a neighbour plan
A notice can give the flat number, anticipated renovation period and the days when the loudest operations are planned. Use a confirmed time window rather than a promise about an exact minute. Name an owner or contractor contact who can check what is happening at the site. Include the information required by HDB and keep a record of when the written notices went out.
If a neighbour needs a quieter period during an examination or a meeting, compare that request with the work calendar. Ask the contractor whether it can move the task within the permitted hours. Tell the neighbour what time was actually agreed and what other work may still happen. If a later change affects the plan, send a clear update.
For a site with several noisy jobs, group the notices around the period of greatest disruption. Add the duration and dates of any follow-up where you have a reliable estimate. A neighbour should be able to tell who to reach if noise starts before the time communicated.
CHAPTER 6 OF 10
Coordinate trades, deliveries and the people living nearby
The most useful site calendar gives each trade an arrival, a work window and a task list. Put noisy work in the applicable window and leave enough time for the task to end within it. Place cleanup and deliveries in separate entries. Ask how workers will carry materials without obstructing shared space, and use the building’s instructions for lifts and common areas.
A contractor may say a job will be completed by late afternoon and still need time to clean up or remove material. Ask when noisy operations will actually end. Give the supervisor a point of contact if a worker arrives too late to finish the task within the window. Confirm the alternative slot before starting an activity that cannot be completed as planned.
Agree who checks the first and last hour Choose a person to confirm what work will start and what should already be finished before the permitted period ends. If the site runs behind, ask that person to review the schedule and move the work rather than improvising. Share changes with the flat owner and the trades that depend on the revised dates.
For an occupied home, plan where family members will be during the loudest work. For a neighbour with a particular need, give the most accurate timing possible and discuss what you can realistically adjust. Keep private household details within the people who need them to coordinate.
Record who can answer questions while the owner is out. A single contact who knows the scope and can reach the supervisor is more useful than several phone numbers with no responsibilities. Ask the contact to document what changed and the next confirmed time.

CHAPTER 7 OF 10
Raise a specific concern about renovation noise
Start with an observation. Write the date, start and end time, where you heard it and what the sound was like. Note whether the work appeared to be from a particular flat and whether a notice was displayed. Keep assumptions separate from facts. If you are uncertain where it originated, ask management or the relevant contact how to identify the work.
A short opening message could say “We heard repeated heavy drilling on Saturday from about 10 to 10.40 am near this level. Could you confirm whether it was part of the renovation and when that work is scheduled next?” This asks for a check rather than attributing intent. Keep a copy of the reply and record whether the activity recurs.
Use the right route for the issue If the issue appears to concern an HDB flat’s renovation hours, permit or conditions, contact the HDB Branch through an official channel and provide the relevant details. If materials are obstructing a shared area or another common-area issue is involved, ask the responsible estate team or Town Council about that separate matter. Use the same dates and descriptions where appropriate.
For a repeated neighbour issue, consider a calm conversation and an appropriate mediation route if the parties need help reaching an arrangement. Check current community dispute guidance if the matter remains unresolved. Avoid entering the site, confronting workers around equipment or sharing identifying recordings publicly.
Keep the response, reference number and next step. If HDB or the building team asks for dates, share a short chronology. If the matter resolves, record the arrangement and check that it works during the next planned work period.
Keep renovation hours separate from ongoing household noise
Some concerns are about a contractor’s permitted hours. Others are about repeated sound from normal occupation or a separate source in the estate. Make a note of the time, type of sound, duration and whether you saw a renovation notice. That lets the person receiving the report identify whether it is an HDB renovation enquiry, an estate matter or a neighbour concern.
For example, repeated tile cutting during contractor work and furniture noise at night can involve different responses. Send the first observation with the work date and permit or notice details if known. For the second, start with a specific description and a practical request to the neighbour. If the source is unknown, say so and ask how it can be established safely.
If an earlier conversation resolved a time issue but new work appears outside the agreement, keep the new dates separate. Compare them with the revised schedule and use the current contact. A short chronology with the exact observations is easier to assess than a long account covering several unrelated noises.
CHAPTER 8 OF 10
Handle a change when noisy work overruns
Tell the contractor to stop an activity if it falls outside the permitted window and confirm how it will be rescheduled. Ask what can safely be left for another day and what instructions apply to the site in the meantime. A different activity may have a different classification. Confirm the work itself before deciding what may continue.
If a neighbour calls after work has started, ask the supervisor what is happening at the stated time. Check the permit and calendar. If a worker has moved to a different task, establish why and what needs to change. Give the neighbour the confirmed next step, including the revised timing if it is known.
Plan a recovery date without losing the paperwork Suppose a new finding delays a Friday job and the next scheduled slot was Saturday. Move noisy work to a suitable permitted day and check how the three-consecutive-day condition and any permit terms apply. Ask HDB if the revised sequence is uncertain. Update the dates for later trades and tell neighbours about the significant change.
If the issue is an unexpected building condition rather than timing, ask the qualified contractor what needs to be assessed before proceeding. Keep a written record of any stop and subsequent approval. Confirm what work was carried out, what remains and how access or barriers will be managed while work is pending.
Retain the old and revised schedules with the final explanation. This gives the household a record if there is a later question about what was authorised or when work happened. Share only the current schedule with the people relying on it for the next visit.
CHAPTER 9 OF 10
Plan around a BTO or resale move
A BTO household may have a defect inspection, rectification, renovation and furniture delivery to schedule. Put each in a separate stage. Confirm when the contractor can enter and what work should wait until a defect has been assessed. Agree on a renovation start that allows time for the permit and written neighbour notice.
A resale household may need to coordinate the outgoing owner’s stay, legal completion and the new owner’s first access. Ask who can authorise each appointment. A contractor’s proposed start date does not establish that the flat is ready. Use the agreed possession arrangements and confirm when the site will be available to the people doing the work.
Allow a realistic gap between noisy work and move-in Mark the heavy work, repairs, cleanup and delivery as different dates. If one stage slips, check which later appointments can be moved. A household can arrange storage or adjust delivery timing if the flat is still being worked on. It is easier to budget for the possibility before booking everything for the same week.
If neighbours are also renovating, each flat remains responsible for its own compliance. Share relevant timings where useful so households know what to expect. When identifying a specific problem, use the address and notice for the relevant work and avoid assigning it to a flat based only on the week the renovation started.
Keep a copy of the end date and the contractor’s final report or invoices. If a later callback involves drilling or other work, check its classification, appointment and any applicable notice. A short follow-up visit still needs to fit the conditions for the work it involves.
CHAPTER 10 OF 10
Use a day-by-day checklist before work begins
Start with the flat, permit, responsible contractor and confirmed scope. Add the days for noisy and other work, with the exact time windows and applicable holiday restrictions. Check how the contractor will complete noisy works within the stated time requirements. Record the date the written notice was given and which nearby units were informed.
Write down who will display any required notice, supervise the scheduled work and answer questions. Give that person access to the permit and the current calendar. Before each noisy day, confirm the tasks and when they must finish. If the schedule changes, check approval and timing before giving the new instructions.
Ask what each person needs to know The owner needs the scope, permit and contact. The contractor needs the exact work and time window. Neighbours need useful timing and an accessible way to raise a concern. The household moving in needs the date when the flat will be ready. Put each item in the record and check it against the latest work plan.
After work ends, save the permit, final scope and any issue record. If a neighbour asked for an update, give them the confirmed end of the loudest work. If an outstanding task still needs a return visit, record what it is and check the correct time for it.
If you are reading because a nearby flat is already noisy, start with the date and time and identify the notice or likely work. Ask the responsible contact to confirm the schedule. If the timing appears outside HDB’s conditions, use the relevant official route with the specific details.
Common questions
Can the contractor hack tiles on Saturday?
HDB’s noisy contractor work rules prohibit it on Saturdays. Check and reschedule the noisy work within the permitted weekday window.
Can a contractor do quiet work on Sunday?
The HDB renovation portal terms prohibit contractor renovation on Sundays and public holidays. Check the instructions applicable to your flat and permit.
Can a neighbour give permission to work outside the hours?
A discussion can help coordinate within the permitted schedule. Follow HDB’s conditions and obtain clarification from HDB if the scope or time is uncertain.
Does the DIY window allow professional heavy drilling until night?
HDB’s DIY guidance and its rules for contractor renovation serve different purposes. Check the work category, permit and applicable hours for the proposed job.
Does this apply to condos?
This guide is for HDB flat renovation. For a condo, ask management for the development’s renovation by-laws and approval conditions.
What if the notice has no time for the loudest work?
Ask the owner or contact on the notice for the dates and expected timing. If the work appears to fall outside HDB’s conditions, record the details and ask the relevant HDB Branch.
