The rule that stops your job isn’t the one you think
Most people plan their renovation hours (裝修時間) in Hong Kong around a law, the Noise Control Ordinance (Cap. 400), and are then blindsided when management shuts the job down on a perfectly legal weekday afternoon. The statute is real and its fines are steep, but it is only the legal floor. The ceiling that actually binds your site is the building’s own house rules. Understand both, in that order, and you can programme a renovation that neither the law nor your neighbours can stop.
This is general guidance; confirm the specifics for your building and works with the EPD and your management office before you programme.
The statute: Noise Control Ordinance (Cap. 400)
Renovation noise is governed by the Noise Control Ordinance (Cap. 400), enforced jointly by the Environmental Protection Department (EPD) and the Police. It bites on a renovation in three distinct ways, each with its own time window and enforcer. Treat the statute as the minimum standard and your building’s house rules as the binding limit.
Powered equipment: the 7pm–7am weekday ban
The rule that matters most for a fit-out concerns powered mechanical equipment, drills, breakers, circular saws. This work is prohibited:
- 7:00pm to 7:00am on weekdays, and
- at any time on a general holiday, which includes every Sunday ,
unless a Construction Noise Permit (CNP) is in force. Inside the weekday daytime window, roughly 7am–7pm, Monday to Saturday, ordinary powered work needs no EPD permit.
Two points routinely trip people up. Saturday is an ordinary working day under Cap. 400, not a general holiday, so the weekday daytime window applies. And percussive piling always needs a permit and is barred at night and on holidays, though that is a new-build concern rather than a flat fit-out one.
Neighbourhood noise and commercial noise
Two other limbs of the ordinance can catch a project:
- Neighbourhood noise bites only at night (11:00pm–7:00am) or on a general holiday, and is judged on a reasonable-person “genuine annoyance” test rather than a fixed decibel reading. It is Police-enforced.
- Commercial or operational noise, from a shop, office or restaurant, not the construction itself, is controlled at any hour against fixed limits and can trigger a Noise Abatement Notice.
The key misconception to correct: ordinary daytime renovation noise inside your own flat is not, by itself, an offence under Cap. 400. What stops a mid-week job is almost always the building’s house rules.
House rules are the real ceiling
The building’s Deed of Mutual Covenant (DMC) and the Owners’ Corporation house rules, made under the Building Management Ordinance (Cap. 344), set the practical limit on site, and they are routinely stricter than the statute. Common house-rule restrictions include Saturday bans, lunch-hour quiet periods, and outright limits on noisy trades to a few hours a day.
By home type, the governing regime shifts:
| Home type | Governing regime | Notes |
|---|---|---|
| Private estate | DMC + OC house rules (Cap. 344) | Registration/permit, refundable works deposit, advance neighbour notice, lift and common-area protection |
| HOS / Green Form / TPS | Private property under a DMC | Management vetting often takes a few weeks; structural change needs an AP + RSE + BD consent (Cap. 123) |
| Public rental (Housing Authority) | Estate Office approval | No structural changes; nuisance can put the tenancy at risk |
| Village house (NT) | Usually no DMC/OC | Only Cap. 400 plus courtesy apply; rebuild uses a Certificate of Exemption from the District Lands Office |
Before works on a private estate, expect to complete renovation registration, pay a refundable works deposit, give neighbours advance notice, protect lifts and common areas, and agree debris-moving times.
The penalties, and who to call
| Offence | Max fine |
|---|---|
| Neighbourhood noise (Cap. 400 ss. 4 & 5) | HK$10,000 |
| Construction noise without a permit in restricted hours (ss. 6 & 7), first conviction | HK$100,000 |
| , subsequent conviction | HK$200,000 |
| , continuing offence | up to HK$20,000 / day |
Who to call: neighbour or night noise → your local Police station; daytime construction noise and commercial-premises noise → the EPD hotline on 2838 3111; evening, night or holiday construction noise → either. Note too that EPD “Designated Areas” in densely built-up districts impose tighter limits on certain equipment, but only during the restricted evening, night and holiday hours, not the daytime window.
How Primeworks handles this
We read the building’s renovation guidelines before we programme a single day of work, then build the permitted noise window straight into the Gantt, so the schedule you approve is one management will actually allow. Powered work is confined to the weekday daytime window and the crew is briefed on hard stop times, which keeps the job clear of both the Police and your neighbours. We also handle the registration, the refundable works deposit, neighbour notice and lift protection up front, so a forfeited deposit or a stopped job never becomes your problem.
