Sinking Fund Balance Guide for NSW Strata Buyers

If you're buying an apartment in NSW, the sinking fund balance is one of the most important numbers in the strata report. A healthy fund means the building can handle major repairs without slugging owners with unexpected bills. A depleted one could mean you're walking into thousands of dollars in special levies shortly after settlement.

This guide explains what a sinking fund is, what a good balance looks like, and exactly how to assess it before you buy. If you're new to strata finances, you may also want to read our beginner's guide to strata levies for broader context on how strata funding works.

What Is a Sinking Fund (Capital Works Fund)?

A sinking fund is the pool of money a strata scheme sets aside for major, long-term expenses — things like roof replacements, repainting the building exterior, waterproofing repairs, lift overhauls, and pipe relining. These are expenses that don't happen every year but are inevitable over the life of a building.

In NSW, the Strata Schemes Management Act 2015 officially renamed the sinking fund to the capital works fund. You'll see both terms used interchangeably in strata reports, real estate listings, and conversations with strata managers. They mean the same thing.

Every strata scheme in NSW is legally required to maintain a capital works fund, separate from the administration fund (which covers day-to-day running costs). Owners contribute to both funds through their quarterly levies. The capital works portion is essentially the building's savings account — money being put away now to pay for expensive work later.

The fund is guided by a 10-year capital works plan, which is a legal requirement for all NSW strata schemes. This plan forecasts what major maintenance will be needed over the next decade and how much money needs to be saved each year to cover it.

Why the Balance Matters for Buyers

When you buy an apartment, you inherit the building's financial position — good or bad. If the sinking fund is well-funded, the building can cover upcoming major works from existing reserves. If it's underfunded, the owners corporation will need to raise the money somehow, and that typically means one of two things: significantly higher quarterly levies, or a special levy.

Special levies are one-off payments that can run from a few thousand to tens of thousands of dollars per lot, depending on the work required. A building that needs $500,000 in waterproofing repairs with only $50,000 in the capital works fund is going to pass that shortfall directly to owners — including you, if you've just settled.

The sinking fund balance also tells you something about how the building has been managed. A consistently well-funded scheme suggests an engaged committee that plans ahead. A chronically underfunded one often points to years of deferred maintenance and governance issues — problems that tend to compound over time.

What Does a Healthy Sinking Fund Look Like?

There is no single number that works for every building. A 6-lot walk-up built in the 1970s has very different capital works needs compared to a 200-lot high-rise with lifts, pools, and underground parking. That said, there are some general benchmarks that can help you gauge whether a fund is in reasonable shape.

As a rough rule of thumb, well-managed buildings in NSW typically hold between $1,000 and $3,000+ per lot in their capital works fund as a baseline. Larger or older buildings with more complex infrastructure often need significantly more. A 100-lot building with $50,000 in the fund ($500 per lot) is almost certainly underfunded, while the same balance for a 10-lot building ($5,000 per lot) might be perfectly adequate.

However, the per-lot figure only tells part of the story. What really matters is whether the fund balance is on track relative to the 10-year capital works plan. The plan should forecast specific expenses (say, $120,000 for repainting in year 3 and $200,000 for lift refurbishment in year 7) and set levy contributions that build the fund up to meet those costs when they fall due.

A fund might have a low balance today but still be healthy if no major works are planned for several years and contributions are steadily building up. Conversely, a fund with a decent headline balance could be woefully short if a $300,000 roof replacement is due next year.

Key factors that influence what "healthy" looks like for a specific building:

• Building age — older buildings generally need larger reserves as more components reach end of life
• Number of lots — more lots means costs are spread more widely, but also often means more complex shared infrastructure
• Building features — lifts, pools, gyms, underground parking, and extensive landscaping all add to future capital works costs
• Construction quality — buildings with known defect histories may need larger reserves for ongoing remediation
• Recent major works — if the building just completed a large project, a temporarily lower balance is expected

Red Flags: Signs of an Underfunded Sinking Fund

Certain patterns in the strata financials should put you on alert. If you spot any of the following, dig deeper before committing — or factor the risk into your offer price. For a broader overview of warning signs, see our guide to 5 red flags in NSW strata reports.

• No 10-year capital works plan — this is a legal requirement under the Strata Schemes Management Act 2015. If the building doesn't have one, or it hasn't been updated in years, the committee likely isn't planning ahead for major expenses.
• Fund balance well below planned targets — compare the actual balance to the projected balance in the capital works plan. A significant gap means levy contributions haven't kept pace with what was forecast.
• Recent or upcoming special levies — a special levy to cover capital works is a clear sign the fund couldn't cover planned expenses from reserves. Multiple special levies in the past few years suggest a pattern of chronic underfunding.
• Large works due with insufficient reserves — if the capital works plan shows a $200,000 expense in the next two years but the fund has $30,000, owners are going to be asked for money.
• Flat or declining capital works levies — building costs increase every year. If capital works levy contributions haven't increased over several years, the fund is falling behind in real terms.
• Visible maintenance being deferred — peeling paint, water stains in common areas, or ageing lifts can indicate that the building is putting off work because the money isn't there.

How to Check the Sinking Fund in a Strata Report

When you order a strata report (sometimes called a Section 184 certificate or strata search), several documents will give you the information you need to assess the capital works fund. Here's what to focus on:

• Financial statements — look for the capital works fund balance on the balance sheet. Compare it to previous years to see if the fund is growing, stable, or being drawn down. Check whether the fund holds actual cash or if the balance includes receivables (money owed but not yet collected).
• 10-year capital works plan — this is the single most important document for assessing fund health. It lists projected expenses year by year and the levy contributions needed to meet them. Check when it was last prepared or reviewed — plans older than five years may not reflect current costs.
• Annual budget — look at the capital works levy amount per lot per quarter. Is it consistent with what the 10-year plan recommends? Has it been increased over time?
• AGM and committee meeting minutes — these often contain discussions about upcoming major works, proposed special levies, or decisions to defer maintenance. Read at least the last two years of minutes.
• Levy arrears report — if a significant percentage of owners are behind on levy payments, the fund may not actually have the cash the balance sheet suggests.

Strata reports can be dense — hundreds of pages of financials, minutes, and legal documents. If you're not sure what you're looking at, our StrataChecks analysis tool can help you make sense of the key financials quickly.

What to Do If the Fund Looks Low

A low sinking fund doesn't automatically mean you should walk away. But it does mean you need to go in with your eyes open and adjust your approach.

• Factor it into your offer — if you can see that a special levy is likely in the near future, reduce your offer price by a realistic estimate of what you'll need to pay. A building with a $20,000-per-lot shortfall is effectively $20,000 more expensive than the listing price suggests.
• Ask your conveyancer or solicitor — they can review the strata report and advise on the financial risks. Some conveyancers specialise in strata purchases and will flag fund issues that a general practitioner might miss.
• Budget for higher levies or special levies — if you decide to proceed, build a financial buffer. Don't stretch your budget to the absolute limit on the purchase price, because the ongoing costs may increase significantly.
• Check if a special levy has already been proposed — AGM minutes and committee meeting notes may reveal that a special levy is already being discussed or has been voted on. If it's been passed but not yet due, you may be liable for it after settlement.
• Look at the bigger picture — a low fund in an otherwise well-managed building (engaged committee, up-to-date capital works plan, good maintenance history) is less concerning than a low fund in a building with governance problems. Context matters.

The Bottom Line

The sinking fund balance is one of the clearest indicators of a building's financial health. A well-funded capital works fund means the building is prepared for the inevitable — roofs wear out, pipes corrode, and lifts need replacing. An underfunded one means those costs will land on owners as lump-sum bills.

Before you buy, always check the fund balance, read the 10-year capital works plan, and look for any signs of chronic underfunding. It takes some effort to dig through strata documents, but understanding the sinking fund can save you from an expensive surprise.
