After Hours Work And Noise Restrictions

Most trade work in an occupied building has a window, and the window is shorter than people assume.

Councils set permitted construction hours. Strata by laws often narrow them further. Commercial buildings and hotels set their own, usually driven by what the tenants and guests will tolerate. Work outside those hours is work that gets stopped.

Who sets what

Council, which sets the outer limits for construction noise by day of the week, including no work or restricted work on Sundays and public holidays.

The owners corporation, through by laws and through the building manager, which commonly tightens the hours, requires notice before noisy work, and sets rules for lift use and for the loading dock.

The building's own management, in commercial premises and hotels, where the restriction is about occupants rather than regulation and is frequently the tightest of the three.

The tenancy or lease, in a retail or office fitout, where the permitted hours for noisy or disruptive work are written into the agreement.

Which means the question is never only what the council allows. On a boutique hotel or a tenanted office floor, the practical window can be a few hours.

The parts of a job that are actually restricted

Not all of a job is noisy, and separating the parts is where the programme is won.

Core drilling, jackhammering, tile removal and concrete cutting are the loud items, and they get scheduled into the permitted window deliberately rather than whenever the trade arrives.

Grinding and sanding are both noisy and dusty, so they carry containment requirements as well as timing ones.

Plumbing isolations are not noisy and they are disruptive in a different way, because they take water off a riser and affect units that have nothing to do with the job. Which is why the isolation is notified separately, and why [isolation valves and why a building needs them](/blog/isolation-valves-and-why-a-building-needs-them) decides how many units are affected at all.

Finishing, painting, fitting off and making good are quiet, and they can run outside the noisy window, which is how a job that looks like it needs a week of access gets done in two noisy mornings and three quiet days.

How we plan around them

The sequence is written to the building's hours, not to the trade's convenience.

That means the noisy work is batched. If three jobs across a building each need twenty minutes of core drilling, those twenty minute slots are done together in one permitted window rather than spread across three weeks of separate approvals and three rounds of notices to residents.

It also means the quiet trades are scheduled into the time the noisy ones cannot use, so the hours outside the window are still productive. Which is only possible when one team holds the whole sequence, because separate contractors each take the window they want and the building absorbs all of it.

That is the same logic as [bathroom work in an occupied apartment](/blog/bathroom-work-in-an-occupied-apartment) and [painting common areas with minimal disruption](/blog/painting-common-areas-with-minimal-disruption), where the programme is built around the occupants rather than around the trades.

Notice, which is most of the complaint management

Residents and tenants tolerate noise they were told about and object to noise that surprised them.

So the notice goes up before the work, it says which days and which hours, it says what will be noisy and what will not, and it names the one contact for questions. A notice with a date range and no hours is the version that generates calls.

In a hotel or a tenanted commercial building the equivalent is working to the building manager's own communication, which is covered in [guest ready, discreetly, trade work in a boutique hotel](/blog/guest-ready-discreetly-trade-work-in-a-boutique-hotel).

When out of hours work is the right answer

Sometimes the only way to do a job is outside normal hours: a retail tenancy that cannot close, a lift lobby that cannot be shut during the day, a water shutdown that affects fifty units.

Those get approved specifically, with the building's consent, and they carry their own conditions on noise, on security and on who is on site. Out of hours work is a planned exception with permissions attached rather than a way around the restriction, and treating it as the latter is how a building withdraws access from a contractor altogether.

For managers, three things make a job run: the permitted hours in writing, the notice period the by laws require, and a nominated contact in the building who can approve a shutdown. With those three, the programme can be built. Without them, every stage waits on an answer.
