What Every Sydney Homeowner Should Know Before Starting a Renovation

Nobody starts a renovation thinking it will go sideways. You have got a clear idea of what you want, a rough budget in mind, and a builder lined up. Simple enough.

Then the wall comes down, and there is asbestos behind it. Or the council wants a DA, and you thought it was complying development. Or the scaffold cannot fit down the side of the terrace, and nobody mentioned that until week two.

Sydney renovations have a habit of surprising people. Not always badly — but almost always in ways that cost time or money or both. A bit of preparation upfront genuinely changes how the whole thing plays out.

The Approvals Question Is Worth Sorting First

A lot of homeowners assume that because it is their property, they can do what they like with it. That is not really how it works in NSW.

Structural changes, facade alterations, new additions, and anything touching a heritage item or strata building all have approval requirements. Some work qualifies as Complying Development, which moves faster than a full DA but still needs a licensed certifier to sign off. Other work needs council approval, which takes longer and sometimes comes back with conditions you were not expecting.

The time to find this out is before you have committed to a builder, not after. A quick conversation with your local council or a private certifier costs you very little. Starting without the right approvals can cost you significantly — stop-work orders are not uncommon, and being told to pull down work that was not properly approved is a genuinely awful situation to be in.

Your Budget Is Probably Not Big Enough

Harsh, but worth saying plainly.

Sydney’s older housing stock — federation homes, inter-war semis, 1960s brick veneer — tends to hold surprises. Old wiring. Crumbling subfloor bearers. Asbestos sheeting behind walls or under floor tiles. Lead paint. These things are not visible when you are getting quotes, and they do not disappear just because the budget is tight.

Most builders will suggest a contingency of fifteen to twenty per cent on top of your contract price. On older properties in suburbs like Glebe, Newtown, or Balmain, experienced trades will quietly suggest more than that. It is not scaremongering — it is just what those houses are like once you get into them.

If you are renovating on a fixed budget with no contingency, you are setting yourself up for a difficult conversation at some point. Better to know that before you start.

What Every Sydney Homeowner Should Know Before Starting a Renovation: Site Access Is a Real Issue

This one catches people off guard more than almost anything else.

Renovation work at height — external renders, roof repairs, upper storey additions, gutter replacement — needs proper scaffolding or access equipment. That seems obvious until you actually try to set it up on a narrow Sydney terrace with a shared fence on one side, a neighbour’s garden on the other, and a two-metre-wide frontage.

Working out how access will be managed is not something to leave until the builder shows up. It needs to be part of the planning conversation, and the cost of scaffold hire or an elevated work platform needs to be in the budget. On jobs above two metres, proper edge protection is not optional — it is a legal requirement under NSW work health and safety regulations, and it is your property the work is being done on.

Ace Building Equipment Hire supplies scaffolding and access equipment to Sydney homeowners and their builders regularly. Getting advice early — before the job scope is locked in — means the right equipment is factored in properly rather than added as an emergency line item halfway through.

Pick Your Trades Based on Experience, Not Just Price

Sydney has plenty of tradespeople. Quality varies a lot.

For licensed trades — electrical, plumbing, structural work — check the licence is current. NSW Fair Trading has an online search that takes about thirty seconds. For your principal builder, ask specifically for references on projects similar to yours in scope and property type. A builder who is brilliant on new builds may not be the right person for a sensitive heritage renovation.

Get a proper written contract. Scope, materials, payment schedule, variation process — all of it in writing. Jobs go wrong less often when both parties are clear from the start. And when something does come up, a written contract is what you fall back on.

Timelines Almost Always Shift

Eight weeks become twelve. Twelve becomes sixteen. This is Sydney renovation reality.

Trades are busy. Materials get delayed. Inspections need to be booked. Unexpected findings add scope. If you are living in the property during the work, or you have made arrangements around a specific completion date, build in a serious buffer. Fixed plans built around a renovation finishing by a certain date have a way of unravelling.

Planning a renovation properly — approvals, realistic budget, right trades, access sorted — does not guarantee everything goes smoothly. But it changes the odds considerably.
