Construction hours, standard conditions and the neighbour

A building job does not run on the builder’s watch. It runs on the consent.

Hours of work, tree protection, sediment fences, dilapidation photos and “no work on Sunday” are not courtesy. They are conditions of development consent. Breach them and the certifier, Council or the neighbour can stop the site. The Planning System Reforms Act 2025 is pushing those conditions toward statewide model wording. Hours of work and tree protection are the items the State has said it will keep.

This post is what that means on a DC site next to someone else’s kitchen window.

The consent is the timetable

The notice of determination lists approved plans and then a string of conditions. Some are “before work starts.” Some are “while work is being carried out.” Some are “before occupation.” Landscape work sits in all three.

Typical construction hours on a house or dual-occ in DC’s catchments:

Council	Weekdays	Saturday	Sunday / public holiday	Extra rule
Inner West	7 am–6 pm (demolition often to 5 pm)	8 am–1 pm, no demolition	No work	High-noise work limited; respite breaks
Woollahra	7 am–5 pm	7 am–1 pm	No work	Piling, rock, jackhammer, machine excavation 9 am–4 pm weekdays, 9 am–1 pm Saturday, 15-minute break each hour
Ku-ring-gai	7 am–5 pm	8 am–12 noon	No work	Machine excavation weekdays only, 45-minute respite 12–1 pm. No machine excavation Saturday

Those windows come from published Council conditions and out-of-hours forms. Always read the actual consent. A panel or Court condition can be tighter.

Out-of-hours work needs a Council permit. Ku-ring-gai will not grant one so the program can catch up. Safety and oversized deliveries are the usual grounds, not “we want the slab finished.” Permits are short — often one event, two days at most — and neighbours must be told.

Construction hours are not backyard mower hours

NSW also has the Protection of the Environment Operations noise rules for residential premises: power tools should not be heard in a neighbour’s habitable room before 7 am weekdays or 8 am weekends, or after 8 pm. That is the law for a homeowner with a leaf blower.

A DA site is different. The consent hours override the weekend mower window. A chipper at 7:15 am Saturday on a Ku-ring-gai dual occ is a breach even if the POEO weekend start is 8 am. A quiet paintbrush after 5 pm may be allowed if Council’s wording permits work that makes no noise. A plate compactor is not a paintbrush.

Rock breaking, piering and jackhammering often have a second, shorter window inside the construction day. Inner West also caps very noisy work and requires a two-hour respite after three hours. Woollahra names the tools. If DC is cutting footings for an 1800 mm masonry fence, that is the list.

What “standard conditions” now look like

The Department already publishes standard residential conditions covering approved plans, erosion and sediment, utilities, dilapidation, tree protection, waste, and works-as-executed. Councils can drop them in rather than inventing new text. The 2025 reforms go further: some conditions will be mandatory model conditions across local, regional and State-significant residential work, including dual occs, dwelling houses and flat buildings. Hours of work, tree protection, sediment and unexpected finds (relics, Aboriginal objects) are named as staying in the pack.

For a landscape contractor that means the same tree fence wording and the same hours can appear on an Inner West terrace and a Gordon dual occ. Read them anyway. Heritage items, bushfire lots and Court consents still grow extra paragraphs.

The conditions that stop a courtyard job

Tree protection before the first trenchAlmost every consent that keeps a tree requires fencing at the Tree Protection Zone before demolition or excavation. No storage, no washout, no skip inside the fence. Roots over a set diameter — often 50 mm — mean stop and call the project arborist. Damage is reported, not patched with soil. That fence is for the neighbour’s tree as well as the one on the lot.

DilapidationWhere the work sits on a boundary — masonry fence, retaining wall, excavation next to a terrace — the consent often wants photos of the neighbour’s structure before work starts. Skip it and every later crack is yours.

Sediment and washoutA courtyard rebuild on a slope in West Pymble or a tight Paddington lane still needs a sediment fence and a place for slurry that is not the gutter. Inner West and Woollahra rangers treat a dirty street as a condition breach, not a tidy-up item.

Approved landscape planSpecies, pot size, soil volume and tree protection are conditions, not suggestions. Swapping a 200 litre canopy tree for a 45 litre stick because the driveway ran late is a modification, not a field decision.

Waste and accessSkips on the street need a permit. Work zones in the Inner West inherit the same hours as the DA. A truck idling at 6:40 am outside a Gordon kitchen is a complaint before the first shovel.

What the neighbour can actually do

They can read the consent. It is on the Planning Portal and on Council’s DA tracker.

They can call Council if work starts before the stated hour, if the tree fence is down, if a jackhammer is running in the restricted window, or if slurry is leaving the site. Rangers enforce conditions. So does the principal certifier.

They cannot invent a 9 am start because they work from home. They cannot stop lawful work inside the hours. They can ask for the dilapidation report if the consent required one and the wall is now marked.

A polite notice the week before a noisy day — piering the fence footing, the chipper for the approved tree — prevents half the calls. It is not a legal duty. It is how you keep the site open.

How DC runs a site against the consent

• Read the hours and the tree conditions the day the consent is issued, not the day the crew arrives.

• Put the TPZ fence up before the skip.

• Photograph the neighbour’s wall and the kerb.

• Start the noisy work after the restricted window, not at the first legal minute if the street is still asleep and the work can wait an hour.

• Do not book a Saturday chipper on a Ku-ring-gai consent that kills machine work at noon — or bans it.

• Keep a copy of the landscape plan on site. The species list is a condition.

• If the program needs Sunday or a 6 am concrete pour, apply for the permit. Do not “just this once.”

• Lighting and irrigation trenches stay outside the structural root zone. The hours condition does not license a trench through a tree Council required you to keep.

If you are the neighbour

Ask for the consent number. Check hours, tree fencing and whether dilapidation was required. Keep a note of dates and times. Call Council, not the person on the shovel, if the breach is real.

If the work is inside hours and the fence is up, the law is on their side. The planning reforms are trying to make that wording the same in every LGA. The neighbour’s weekend is still the reason Saturday dies at 1 pm in the Inner West and at noon in Ku-ring-gai.
