HDB renovation hours in Singapore: what is allowed, and when
HDB renovation hours in Singapore run in two bands. General renovation work in an HDB flat is allowed from 9:00am to 6:00pm on Mondays to Saturdays, while noisy work — demolishing walls, removing wall or floor finishes, cutting tiles, and heavy or excessive drilling — is allowed only from 9:00am to 5:00pm on weekdays. No renovation of any kind is allowed on Sundays and public holidays, and noisy work is additionally barred on Saturdays and on the eves of New Year's Day, Chinese New Year, Deepavali, Hari Raya Puasa and Christmas Day.

The two bands of HDB renovation hours, and which one applies to your work
HDB sets two different windows and the difference between them decides your programme. HDB's renovation terms state that "general renovations should only be carried out between 9:00am and 6:00pm on weekdays and Saturdays" with "no renovations are allowed on Sundays and Public Holidays", while "restricted renovations 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 only" (HDB, Important Information on Renovations).
Multiply those bands out and the loudest phase of a Singapore HDB renovation has 40 usable hours a week — eight hours across five weekdays — against 54 hours for everything else, being nine hours across six days. Carpentry installation, painting, plastering, screeding, electrical trunking and tiling laid over existing finishes fall in the wider band; hacking, tile removal and floor screed removal fall in the narrower one. A programme that assumes hacking can spill into Saturday is a programme that will slip.
Saturday, Sunday and public holiday renovation in an HDB flat
Saturday is a working day for general renovation in an HDB flat and not for noisy work. HDB permits general renovations from 9:00am to 6:00pm on Saturdays but states that restricted renovations "are not allowed on Saturdays, Sundays, Public Holidays and the eves of New Year's Day, Chinese New Year, Deepavali, Hari Raya Puasa and Christmas Day" (HDB, Important Information on Renovations).
Sundays and public holidays are closed entirely. HDB's wording is unqualified — "no renovations are allowed on Sundays and Public Holidays" — and MyNiceHome repeats it in its renovation guide, listing general renovations as allowed Monday to Saturday 9am to 6pm and not allowed on Sunday and public holidays (MyNiceHome, How to Renovate Your HDB Flat). Owners who plan around a public holiday long weekend, expecting the site to keep moving while they are away, should count those days as lost rather than gained: a Sunday plus a public holiday is two consecutive days on which no renovation work may be done at all.
What counts as noisy work, and how long it may run
HDB names the noisy category explicitly rather than leaving it to judgement: demolishing of walls, removing wall or floor finishes, cutting of tiles, and heavy and excessive drilling works (HDB, Important Information on Renovations). Anything in that list is confined to weekdays, 9:00am to 5:00pm.
There are two limits on top of the clock that most homeowners never hear about. HDB states that at any given time only 2 of the handheld power tools approved by HDB, or their equivalent, can be used, and that "renovation contractors cannot take more than 3 consecutive days to demolish walls and/ or remove wall and/ or floor finishes" (HDB, Important Information on Renovations). A quotation that shows a week of hacking for a single flat is describing something HDB does not allow, and the honest response is to reduce the hacking scope rather than stretch the days. Ask for hacking and debris disposal to be priced as its own line so that the scope, and the noise it implies, is visible before work starts: TO FILL: hacking and debris disposal, 4-room resale flat.
Renovation hours for electrical work are stated separately
HDB's electrical works guidelines carry their own timings, and they are not identical to the general renovation ones. That page states that for electrical work "no work is to be carried out before 8am or after 6pm", that noisy work such as cutting of tiles, demolition of walls and removing wall or floor finishes "should only be carried out on weekdays between 9am to 5pm", and that "noisy works cannot be carried out on Saturdays, Sundays or Public Holidays" (HDB, Renovation Guidelines for Electrical Works).
Where two HDB pages phrase a limit differently, the safe operating assumption on site is the stricter one, because the consequence of guessing wrong falls on the flat owner. Treating 9:00am as the start of noise and 5:00pm as the end of it on weekdays satisfies both pages.
The notice you owe your neighbours before renovation starts
HDB puts neighbour notification in writing rather than leaving it to goodwill. Under its timings guidance HDB asks that you or your renovation contractor "inform your neighbours staying within a radius of 2 units at least 5 days in advance before renovations begin with written notice", and separately requires that after getting the renovation permit, the owner and the renovation contractor display the Notice of Renovation outside the flat until all the renovations are completed (HDB, Important Information on Renovations).
HDB adds a second, easily-ignored request in the same section: "when possible, close the main door of your flat while works are ongoing, to help reduce noise disturbance to your neighbours" (HDB, Important Information on Renovations). A written notice that names the start date, the expected noisy days and a contact number costs nothing and is the cheapest piece of dispute prevention available on an HDB renovation in Singapore.
DIY drilling and hammering in your own flat
DIY work by the owner is treated differently from contractor work, and HDB's wording is advisory rather than prohibitive. HDB says that if you plan to carry out DIY works you should limit them to between 7:00am and 10:30pm and keep noise to a minimum, and asks owners to "try not to carry out any Do-It-Yourself (DIY) works involving drilling and hammering from 10.30 pm to 7.00 am as these generate noise which may disturb your neighbours", informing neighbours beforehand if those times cannot be kept (HDB, Important Information on Renovations).
The wider DIY window HDB describes is not a loophole for a contracted renovation. HDB addresses its timings guidance to "you or your renovation contractor" and asks that renovation work be carried out only between the stipulated timings, so the 9:00am to 6:00pm and 9:00am to 5:00pm bands attach to the renovation itself rather than to whoever happens to be holding the drill (HDB, Important Information on Renovations).
When a neighbour's renovation runs outside the permitted hours
If hacking starts at 8:00am, continues past 5:00pm, or runs on a Saturday in an HDB block, the first thing to look for is the Notice of Renovation outside the flat, because HDB requires it to be displayed until all the renovations are completed and it identifies the contractor responsible. HDB's published enforcement lever is aimed at that contractor rather than at the neighbour: HDB operates a Demerit Points System under which a contractor is delisted from the Directory of Renovation Contractors on receiving a total of at least 24 demerit points within 24 months, with a 1-year suspension attached, and states that contractors listed in the DRC must ensure their work "does not cause any nuisance to neighbouring units" (HDB, Directory of Renovation Contractors).
The rules bind the flat owner too. HDB tells owners to "comply strictly with the permitted time stipulated by HDB so as not to inconvenience your neighbours", and states that an owner may face prosecution for contravening the Housing and Development (Renovation Control) Rules (HDB, Important Information on Renovations); those Rules provide for a fine not exceeding S$5,000 (Housing and Development (Renovation Control) Rules, Singapore Statutes Online). Noble Interior Design Pte. Ltd. is listed in HDB's Directory of Renovation Contractors (DRC Ref: HB-12-5230A, UEN 201722629H) and is CaseTrust-accredited.
Renovation hours in condominiums and private homes in Singapore
HDB's renovation hours apply to HDB flats and nothing else. A condominium renovation in Singapore runs on the management corporation's by-laws and renovation house rules, which are set development by development, are frequently stricter than HDB's on weekend noise, and are not published in any central register — so the only reliable source is the current house rules from your managing agent, obtained in writing before the schedule is fixed. For landed housing there is no equivalent published renovation-hours rule from HDB at all; noise between neighbours is handled under the general law on nuisance rather than under HDB's renovation terms, and a sensible contractor still works to the HDB bands as a default.
The rule, in the regulator's own words
A permit from HDB is required before hacking or altering any walls in a flat.
