The Ultimate Guide to Multi-Residential Property Upkeep: Preventing Costly Repairs Before They Start

# The Definitive Manual for Multi-Residential Property Maintenance: Avoiding Expensive Fixes Early On

Each owners corporation encounters a similar silent expectation every year: keep levies low or finance the works that safeguard the building. The committees that go for low levies rather than adequate financing almost always encounter higher costs later on, and more often than not they’ll have to cover it with an unanticipated special levy. This manual aims to help you avoid this situation.

The legal duty behind the maintenance schedule

According to the Strata Schemes Management Act 2015 (NSW), the owners corporation is required by law to maintain and repair common property. Lot owners can’t demand this through repeated emails and expect it to happen. In the same way, committees can’t ignore it by citing lack of funding, because the obligation is there whether the cash is or not. It’s an indisputable fact.

While the legal framework doesn’t require owners to raise a special levy immediately after you hand them a notice of a by-law breach to repair the water damage from their overfilled bath, they do have to schedule and perform the work to an approved standard. Should they fail to protect the common property from further damage for the time it takes to get it sorted, or fail to follow through on the fix, you’d apply to a tribunal for an order.

It’s a responsibility, not a request for quotes.

Too hard to reach? Too special a case? Too early or too late to get through? Whatever the argument, the maintenance must be done – so the bill should replace the blank looks.

Where common property ends and lot ownership begins

Maintenance disputes in strata buildings often occur because of the boundary – whose responsibility is it question. When the boundary isn’t clear, simple issues become complicated and the damage can get much worse. As a general rule, if it is structural, external, or on the ‘supply’ side of a service connection, then it is owners corporation responsibility. If it is on the ‘delivery’ side of a service connection then it is typically the lot owner’s.

For owners/committees looking to prevent disputes by making the boundary explicit in advance, here is a quick rundown of who owns the problem in common scenarios:

Owners Corporation

• Roofs, external walls, and structural framing
• Balcony membranes and waterproofing behind tiles
• Windows and window frames (in most schemes, though by-laws vary)
• Plumbing and electrical infrastructure up to the point it enters a lot

Lot Owner

• Anything inside the lot boundary line
• Internal fixtures, fittings, and finishes they have installed
• Anything on ‘the other side of the wall’ from shared service infrastructure (plumbing, electrical, air conditioning), including wet areas where a failed waterproofing membrane sits behind a tiled surface the owner considers “theirs” but is legally common property or shared infrastructure

Why the 10-year capital works fund plan is the most important document you own

If there is one thing you remember from the following explanation, let it be this: the 10-year capital works fund plan is the best maintenance tool you have access to in a strata scheme, and yet, we see most committees treat it as something for the filing cabinet rather than the strategy shelf.

It’s intended to forecast your major spending over 10 years – roof replacement, lift modernisation, waterproofing remediation, facade repainting – so that your capital works fund (sinking fund, as was) can actually foot the bill when the time arrives. The rough guide from NSW Fair Trading is that owners’ corporations should be putting aside enough money to accumulate 0.3% to 0.5% of the building’s total replacement value in the fund each year. That’s a useful stress test. If your scheme’s annual contributions fall well below that range, you aren’t underfunding a line item; you’re underfunding the building.

Schemes that keep this plan updated every couple of years, and actually raise levies in line with it, rarely get a shock. Schemes that let it languish find that the roof just happens to need replacing the month that someone raises the topic at a general meeting, and then boom, we’re hitting the vote on a special levy that no one is thrilled about.

A live 10-year plan does something else: it turns multiple unrelated repair conversations into one funding conversation. Instead of having separate middle-of-the-night debates over the roof, the lifts, and the facade, you’re managing one piece of paper and one sum.

The building envelope is where the real money gets spent

Water gets in, builds your repair bill, devalues your building, and inconveniences your residents. But the blow-out costs are what really hurt. Fixing waterproofing defects costs five times what it should if remediation has been left too late. And waterproofing defects left too late lead to structural defects – a media report of a concrete slab cancer diagnosis likely started with preventable waterproofing defects.

It goes without saying that a catastrophic structural failure costs many, many times more to repair than catching waterproofing defects 30 years earlier, back when the costs were cosmetic. What does need saying is that the longer a waterproofing defect goes unnoticed, the more additional structural, fire, BCA, and aesthetic defects it leads to. If a building owner suddenly sees $20,000,000 worth of defects in their building, they almost certainly saw the first $5,000,000 coming, turned a blind eye, and let their repair curve go exponential.

This is why routine inspections should prioritise water entry points specifically – roofs, balconies, external wall junctions, window frames, wet areas – rather than a generic walk-around looking for anything that looks “off.” A building can look fine cosmetically and still be losing structural integrity behind a bathroom wall. Inspectors who know where water travels through a building envelope catch these problems years before an owner notices a ceiling stain.

Here’s the reality that most asset committees don’t want to face but must confront: a $5,000 membrane repair that you put off yesterday becomes a $50,000 structural repair or replacement within a couple of planning cycles. Once moisture gets past the failing membrane and starts degrading structural members or corroding reinforcement, that’s it: you’re rebuilding, not repairing. Concrete spalling, structural timber and reinforcement replacement, steel members, and weld-on plate structural bracing or replacement all signal that you’ve left it too late.

The decision point driving all this is simple: if the asset (membrane, roof covering, sealant, coating) is still within its estimated serviceable life, repair it now. If it’s past that and showing signs of early failure, replace it now as part of the current capital works bid where you have the opex funds available. Postponing the end-of-life replacement won’t save you any net present value, but it will certainly put at risk your users and your reputation.

Condition assessments beat waiting for complaints

Most strata schemes run their maintenance program on complaints. A tenant reports a leak, a resident emails the strata manager about a crack, and the committee reacts. That’s not a maintenance program – it’s damage control, and it only ever catches problems after they’ve become visible, which in a building envelope context means after they’ve already caused real damage.

A better approach is commissioning a professional building condition assessment every three to five years. A qualified building consultant inspects common property systematically – roof, facade, balconies, structural elements, services – and produces a condition-based maintenance schedule ranked by urgency and remaining serviceable life. This becomes the evidence base for the 10-year capital works plan, replacing guesswork with actual data about what’s degrading and how fast.

For older buildings, or those recently out of their defects liability period, a condition assessment is particularly valuable. It draws a clear line between defects the original builder should still be liable for and normal wear the owners corporation now owns. Missing that window means the OC pays for repairs that should have been the builder’s responsibility.

Executing the plan: why one accountable partner beats a dozen tradespeople

Most volunteer committees do the best they can with the time they have. They can hardly be expected to schedule inspections across multiple trades, or find the right contractor, or remember whether they’ve even done an inspection in the first place. Preoccupy these people with something else over the two months an impending compliance deadline nears and suddenly a decade-old crack seems like a minor problem.

There are few complaints about the fundamental maintenance schedule because that’s agreed in advance. It’s the poor execution of that plan that lets buildings down. It’s silent, seamless, and easily overlooked – fragment your maintenance program and you end up making one phone call for your half-yearly inspection and another for your fire services, mechanical ventilation, and waterproofing over the other half.

The fix is consolidating execution under a single accountable provider. Committees that engage a specialist firm for strata building maintenance Sydney get a coordinated inspection routine, a consistent point of contact for scoping and quoting works, and a contractor network that’s already been vetted rather than sourced under time pressure during an emergency. Of course, the 10-year plan isn’t perfect. It’s an estimate based on the likely life of elements in your building and the costs involved in their repair or replacement. Your committee will have done its due diligence revising these numbers based on the real-world condition of your building, but they’re still estimates and you will get some bad surprises. Wear and tear isn’t linear and funds are always more limited than we would like so we’re back to prioritizing work that’s urgently required.

Compliance deadlines that can’t slip

Some maintenance items you wouldn’t classify as discretionary at all – they’re statutory deadlines with legal consequences attached regardless of budget.

Most commonly, annual fire safety statements demand that particular essential safety measures (often fire extinguishers, sprinkler systems, exit lighting, and fire doors) are inspected and certified by due date. In many states, this isn’t just a matter of commissioners and insurance brokers covering themselves with the paperwork. If you don’t have that completed inspection report and signed statement on record, you can be fined, and in some jurisdictions, the owners corporation and individual committee members can be criminally liable.

Buildings within an even broader age range must have an asbestos register on site and current. That register directly shapes how any renovation or maintenance work involving older materials must be scoped and managed.

These life-and-safety dates should sit on the same calendar as the capital works plan, not in a separate compliance folder someone checks once a year if they remember. A missed statutory deadline is a liability event that no amount of remedial spending afterward can undo. You can fix a leaking roof after the fact. You can’t retroactively un-miss a fire safety certification deadline.

Records are your best asset in a dispute

Every group sooner or later has to confront a disagreement – a defect claim against a builder, an insurance claim following storm destruction, or a shouting match at a general meeting over why levies are going up again. In each of those scenarios, a paper trail of maintenance is your best defence.

A clear account of scheduled inspections, condition reports, and completed works is an airtight argument that the owners corporation obtained estimates, undertook maintenance, and didn’t identify any issues at the time. That paper trail impacts insurance premiums, as insurers factor in the record of maintenance and previous claims in their underwriting. It matters in defect litigation, often being the central question in court: when was the defect identified versus when was it reported? And it matters when a lot is sold, as buyers and their conveyancers go through strata records with a fine-tooth comb prior to settlement. Buildings with a thin folio are unprotected on each front. Buildings with a documented history have a club.

Putting the sequence together

There is a sequence of events here, and by jumping phases you only end up dealing with the same issues later.

Step one is updating the 10-year capital works fund plan with current condition data, not five-year-old assumptions. Step two is ensuring it is properly funded against the 0.3% to 0.5% benchmark. Step three involves mapping out statutory compliance deadlines and engaging the maintenance partner. None of these steps is particularly costly if you’re organized about it. But skip them all together, and you have a classic case of small problems turning into big ones. We know how this ends. Costly emergency maintenance is far more intrusive than a planned, cost-effective program.
