Renovating in a Strata Building: What to Expect (Sydney)

Owners worry about the wrong thing. The kitchen and the bathroom get built the same way in a unit as in a house. What catches people out is everything around the build: the lift you cannot use without booking it, the 8am start the building enforces, the neighbour who reports the noise, the acoustic test on your new floor, and the levy notice that arrives mid-project. This page walks the lived reality of a strata renovation in Sydney, with the real rules and the real sources, so nothing on the list surprises you.

What is it actually like to renovate in a strata building?

It is a logistics job wrapped around a building job. Before a single trade turns up you have to get the work approved, book the lift and loading dock, schedule deliveries to the hour because there is nowhere to store anything, work inside restricted hours that remove your weekend catch-up, keep the noise within an acoustic limit, and protect every metre of common property between the front door and your unit. Get those right and the renovation runs clean. Get them wrong and you collect complaints, stop-work notices, and a damage claim against your bond.

Booking the lift and the loading dock

The service lift is the first thing you book and the thing most likely to slow you down. In a high-rise, every sheet of plasterboard, every tile pallet, and every bag of demolition waste moves through one shared service lift on an allocated time slot. Building management padding goes up to protect the lift, deliveries are staged to match the work because there is no driveway and no storage, and waste leaves the same way, often into a booked skip or builder's bin. Miss your window and the trade stands idle while the lift carries someone else's furniture.

Most buildings also hold a renovation bond before work starts, commonly $500 to $2,000 and more in premium buildings, refunded once a common-property inspection confirms nothing was damaged. Some require proof of the builder's public liability and workers compensation insurance on file first. These are building rules, not law, so they vary, and the only way to know yours is to read the building's renovation guidelines before you quote the job.

What hours can tradespeople actually work?

Your building's hours, which are usually tighter than the law. NSW noise rules set a statutory floor, but almost every strata building enforces stricter renovation hours through its by-laws and building management. You work to whichever is tighter, and in practice that is the building.

Statutory limits are the times power tools must not be heard in a neighbour's habitable room under the NSW EPA neighbourhood noise rules (Protection of the Environment Operations (Noise Control) Regulation 2017). Building rules are typical Sydney strata renovation conditions and vary by scheme.

This is not a footnote, it is a schedule problem. Losing weekends and starting late shortens the working day, which stretches the calendar, and a longer calendar is a real holding cost on a project you are often not living in. It is one of the reasons an apartment renovation runs longer than the same work in a house, which we cover in our apartment renovation cost guide.

Telling your neighbours, and why the building makes you

Notice is not just courtesy, it is usually a condition of approval. Many buildings require you to notify the owners corporation and adjoining residents before work starts, and the EPA itself advises letting neighbours know in advance of building work. In a shared building this matters more than people expect: neighbours hear demolition through the slab within minutes, and an owner who was warned is far less likely to lodge a complaint that triggers a building-management visit or a Tribunal dispute.

That is the pattern that turns a normal renovation into a fight. The fix is simple: a short letter to the committee and the immediate neighbours before the first noisy day, naming the work, the dates, and the hours.

Acoustic underlay and the star rating

If you are putting hard flooring over another unit, your building almost certainly requires an acoustic star rating, usually 4 to 6 stars. The Association of Australasian Acoustical Consultants (AAAC) rates impact noise on a 2 to 6 star scale, where 3 stars is basic compliance and 5 or more is good to excellent. Timber, laminate, and hybrid floors transmit footfall to the unit below, so an acoustic underlay sits between the floor and the slab to bring the impact noise down to the building's standard.

Protecting common property

Everything between the street and your front door is common property, and any damage to it is your problem. That is the lobby, the corridor carpet, the lift, the stairwell, and the car park. The renovation bond exists for exactly this, and it is refunded only after the work is done and the common areas pass inspection. A careful job protects the route in and out from day one: hard floor protection through the corridors, padding in the lift, corner guards, and a clean-as-you-go rule so nothing gets ground into the carpet. It sounds minor until a scuffed lobby wall costs you the bond.

The special levy that lands mid-renovation

This one has nothing to do with your renovation and you still pay it. The owners corporation can raise a special levy at any general meeting to fund building repairs, and every owner pays their share whether they are renovating or not. In Sydney's older and defect-affected blocks the common culprits are cladding rectification, concrete and waterproofing repairs to common property, and lift replacement, and the bills run well into five figures.

You cannot control when a levy is struck, but you can avoid making it worse. Check the latest minutes and the capital works fund before you commit to a large renovation, so you are not pouring a premium budget into an apartment that is about to be hit with a major building repair.

Run in order, the strata layer is manageable. The sequence below is the path almost every Sydney apartment renovation follows before the build even starts.
