Can I renovate a strata property?
Yes, you can renovate a strata property, but what you're allowed to do without approval depends on whether the change is cosmetic or structural. Cosmetic work like painting, new flooring finishes, or built-in wardrobes usually needs no more than notifying the owners corporation, while anything affecting the building's structure, common property, or external appearance needs formal approval first. Skipping approval can leave you liable for reinstatement costs even after you've paid for the work.
The Fuller Picture
NSW strata law splits renovations into three tiers, and which one your project falls into determines how much approval you need. Cosmetic changes — repainting, hanging shelves, replacing carpet with carpet — generally don't need owners corporation approval at all. Minor renovations that affect the appearance of a lot but not its structure, such as installing hard flooring, reconfiguring a kitchen within the existing footprint, or adding air conditioning, need a resolution passed by the owners corporation at a general meeting. Major renovations — anything involving structural changes, waterproofing, or work on common property like external walls or balconies — need a special resolution and often an engineer's report before work can start.
Where it gets more complicated is that "structural" isn't always obvious to a buyer walking through with renovation plans in mind. Removing an internal wall that looks non-load-bearing might still be classified as structural if it affects the building's fire rating or sits above a service riser. Waterproofing membranes in bathrooms and laundries are common property in most schemes, which means even a straightforward bathroom renovation can trigger the major renovation process because you're disturbing common property, not because the room itself needs structural work. The by-laws for the specific scheme also layer on their own restrictions — some buildings prohibit hard flooring altogether because of noise transmission to the unit below.
The Strata Schemes Management Act 2015 (NSW) sets out these three renovation categories and the approval process for each, and most owners corporations now have a renovations by-law that spells out documentation requirements, such as needing a licensed contractor, compliance certificates, and sometimes a bond against damage to common property. Buyers planning renovations should ask for a copy of the by-laws and any existing renovation guidelines before exchange, not after settlement.
What This Means for Your Purchase
If a renovation is part of why you're buying a particular property, the strata report needs to answer a specific question before you commit: is this a cosmetic change, or will it touch common property? A kitchen upgrade that's purely cosmetic can usually proceed on your own timeline after settlement, but a major renovation needs owners corporation approval that can take weeks or months, with no guarantee it will be granted. Buying with a specific renovation plan in mind and finding out afterwards that the by-laws restrict it is one of the more common sources of buyer regret in strata property.
The financial implication sits in two places. First, major renovations usually require the buyer to cover the cost of an engineer's assessment and any make-good bond, on top of the renovation itself, which can add several thousand dollars to a budget that didn't account for it. Second, unapproved work — even work done by a previous owner — can become your liability once you own the lot, because the owners corporation can require reinstatement of common property regardless of who carried out the change.
Timing matters too. If your renovation plan is a condition of the purchase being worthwhile, it's worth raising informally with the strata manager or owners corporation before you're locked into the contract, since verbal indications of likely approval — while not binding — give you a much better read on the risk than assuming it will be fine.
How This Shows Up in the Illawarra
Strata buying in the Illawarra is concentrated in specific pockets — Wollongong CBD, North Wollongong, Corrimal, and the newer developments around Shellharbour and Flinders — and many of these buildings are recent enough that renovation by-laws are already well documented, which works in a buyer's favour. Older strata blocks in suburbs like Fairy Meadow or Warrawong can be a different story, with smaller owners corporations, less formal record-keeping, and by-laws that haven't been updated in years, making it harder to get a clear answer on what's actually allowed before you buy.
Coastal apartment buildings, particularly older beachfront blocks in Wollongong and Thirroul, often carry tighter restrictions around balcony and external work because of exposure to salt air and the higher cost of maintaining waterproofing and render on those elevations. Buyers drawn to these buildings for the view should factor in that the same coastal position that makes the apartment appealing is often why the owners corporation is cautious about approving structural changes.
Frequently Asked Questions
Do I need approval to repaint or replace carpet in my strata unit?
No, cosmetic changes like painting and carpet replacement are usually classed as cosmetic work and don't need owners corporation approval, though it's worth checking the by-laws for any colour or material restrictions.
What's the most common point of confusion about strata renovations?
Buyers often assume "structural" only means load-bearing walls, when in NSW it also covers work that affects waterproofing, common property services, or the building's fire rating — a bathroom renovation can be classed as major even without touching a wall.
Does this matter more for first home buyers?
Yes, because first home buyers are more likely to be buying with a tight budget and a mental plan to "fix it up later" — finding out that plan needs approval, cost, and time you hadn't budgeted for can change the numbers on the purchase.
When should I find out about renovation restrictions — before or after I buy?
Before exchange. Once you own the lot, you're bound by the existing by-laws and approval process, and there's no cooling-off equivalent for discovering a renovation isn't allowed.
Can I negotiate on price if a property needs major renovation work that requires approval?
Yes — factor the cost and uncertainty of the approval process into your offer, and treat unapproved past renovations disclosed in the strata report as a genuine risk to price in, not a minor issue.
Does a buyers agent help with strata renovation questions?
A buyers agent can help you read the strata report and by-laws with a critical eye and flag renovation risk before you fall in love with a property, though the formal approval decision always sits with the owners corporation.
