Does Strata Insurance Automatically Cover a Renovation Inside Your Unit?

Generally yes, up to an automatic allowance built into most strata policies. Ongoing construction work is still worth disclosing as it happens though, not just once the final cost is known and the sum insured needs a look.

Strata insurance generally covers a renovation inside a unit automatically, up to an allowance built into most policies for owners’ fixtures and improvements. A renovation that exceeds it can leave the extra value undeclared and effectively uninsured until the strata scheme’s sum insured is actually updated to reflect it. Ongoing construction work is worth disclosing as it happens too, not just once the final cost is known. If it isn’t clear whether a particular block of units is actually strata-titled in the first place, that’s worth confirming before any of this applies.

An automatic allowance

most strata policies pick up ordinary owner improvements without separate notice

A ceiling, not a guarantee

a high-end reno can genuinely exceed it, leaving the extra value undeclared

Disclose it early

ongoing construction work is worth raising before it starts, not just once it's done

Does strata insurance actually cover a renovation automatically?

Generally yes, up to a point. Most strata policies build in an automatic allowance for owners’ fixtures and improvements. It commonly sits in the order of a couple hundred thousand dollars per lot, though the exact figure varies by insurer. This allowance exists so an ordinary kitchen refresh or bathroom update doesn’t require every owner to notify the scheme individually. It isn’t unlimited, which is exactly where a gap can open up.

The automatic allowance covers the renovation most owners do. It doesn't automatically stretch to cover the one that goes well beyond it.

Should a renovation be disclosed before it starts or only once it’s finished?

Before it starts, ideally. Ongoing construction changes what’s actually happening at a property while it’s underway. That’s worth disclosing to a strata manager or broker as a matter of course, since it’s a separate and earlier step than the sum insured question. Treating disclosure as something that only matters once the final cost is tallied up misses this earlier step entirely. The same principle applies on the commercial strata side of a scheme too, where an automatic allowance and a disclosure expectation both sit behind the policy.

What happens once a renovation is worth more than that allowance?

The amount above the automatic allowance may not actually be reflected in the building’s sum insured unless it’s specifically declared and added. A high-end kitchen or bathroom renovation or work involving real structural change can realistically exceed a standard allowance. The gap between what was actually spent and what the policy assumed is usually only discovered once a claim is being assessed.

Does an owner actually need to tell the body corporate about a renovation?

Generally yes. Doing it promptly is the safer default, particularly for anything likely to be above the scheme’s automatic allowance. Some schemes expect notification above a set value as standard practice. Treating a significant renovation as worth raising, rather than assuming it falls neatly under the automatic cover, is the better habit to build.

Whose responsibility is it to actually declare the renovation?

Practically, it falls to the individual owner, since they’re the one who actually knows what work was done and what it cost. The body corporate has no way to declare an improvement it was never told about, even though the resulting adjustment affects the scheme’s policy as a whole. This connects to the broader strata versus non-strata distinction too. Knowing which structure applies is the starting point for working out who’s actually responsible for declaring and insuring anything.

Key Takeaways

  • Most strata policies build in an automatic allowance for owners' fixtures and improvements, commonly in the order of a couple hundred thousand dollars per lot.
  • Ongoing construction work is worth disclosing as it happens, not just once the final cost is known.
  • A high-end renovation can genuinely exceed the automatic allowance, leaving the extra value undeclared unless the sum insured is specifically updated.
  • Declaring a significant renovation is practically the individual owner's responsibility, since the body corporate can't act on what it was never told.
  • A gap like this is usually only discovered once a claim is being assessed, which is exactly why raising it earlier is the safer habit.

Frequently asked questions

Does strata insurance automatically cover a renovation inside a unit?

Generally yes, up to an automatic allowance most policies build in for owners' fixtures and improvements. This allowance commonly sits in the order of a couple hundred thousand dollars per lot, though the exact figure varies by policy and insurer. It's designed to pick up ordinary improvements without every owner needing to notify the scheme individually.

What happens if a renovation is worth more than the automatic allowance?

The amount above that allowance may not actually be reflected in the building's sum insured unless it's specifically declared and added. A high-end kitchen or bathroom renovation or significant structural changes can realistically exceed a standard allowance, leaving a real gap that's only discovered once a claim is being assessed.

Should a renovation be disclosed before it starts or only once it's finished?

Before it starts, ideally. Ongoing construction or renovation work changes what's actually happening at a property while it's underway. That's worth disclosing to a strata manager or broker as a matter of course, separate from the question of whether the finished value ends up above the automatic allowance. Treating disclosure as only a sum insured question, raised once the work is done, misses this earlier step.

Does an owner need to tell the body corporate about a renovation?

Generally yes. Doing it promptly, ideally before work even starts, is the safer approach, particularly for anything above the scheme's automatic allowance. Some schemes expect notification above a set value as a matter of course. Treating it as worth raising rather than assuming it falls under the automatic cover is the better default.

Is declaring a renovation the owner's responsibility or the body corporate's?

Practically, it falls to the individual owner, since they're the one who actually knows what work was done and what it cost. The body corporate can't declare an improvement it doesn't know about, even though the resulting sum insured adjustment affects the scheme's policy as a whole.

What kind of renovation is most likely to exceed the automatic allowance?

Higher-end kitchen or bathroom upgrades, structural changes and built-in features like custom cabinetry or ensuite additions are the kinds of work most likely to push past a standard allowance. A straightforward cosmetic refresh is far less likely to come close to it.

Does an undeclared renovation only affect the owner who did the work?

The immediate claim outcome mainly affects that owner's own improvements if something goes wrong. Underinsurance on the building's overall sum insured is a different, shared risk. It affects every lot owner, which is exactly why the scheme's sum insured is worth reviewing properly at renewal.

What should an owner tell their strata manager or broker after a renovation?

The scope and cost of the work, when it was completed and whether it involved structural changes or just fixtures and finishes. This is usually enough for a broker to work out whether the automatic allowance already covers it or whether the sum insured needs a specific update.
