I’ve been in real estate long enough to see buyers skip building inspections because they didn’t want to spend $500-800 or they were worried another buyer would swoop in during the inspection period. Sometimes they got lucky. Often they didn’t.

In 2026, skipping a building inspection is a worse idea than it’s ever been. Here’s why, and what a proper inspection actually involves.

The Dual Problem

Sydney’s housing stock splits into two problematic categories. There’s the older housing stock — pre-1990s homes that are 30-60 years old — and there’s the newer stock built during the apartment boom of the 2010s. Both present inspection issues, just different ones.

Older homes have wear-and-tear problems. Roofs that need replacing, electrical systems that predate modern safety standards, timber pest damage, cracking foundations, asbestos in unexpected places. These are predictable issues with old buildings, but they’re expensive to fix.

Newer apartments and townhouses have construction defect problems. Waterproofing failures, structural cracking, cladding issues, poor drainage. These shouldn’t exist in buildings less than 15 years old, but they do, and they’re increasingly coming to light as buildings age past their initial warranty periods.

What an Inspection Catches

A proper building and pest inspection covers:

• Structural integrity (foundations, load-bearing walls, roof structure)
• Timber pest activity (termites, borers)
• Roof condition and likely replacement timeline
• Plumbing systems (visible pipes, drainage, hot water systems)
• Electrical safety (switchboard condition, wiring standards)
• Moisture and water damage (bathrooms, under floors, around windows)
• External drainage and site water management

The inspector produces a report that categorises issues as major defects (structural problems, active termite infestation), minor defects (wear and tear requiring maintenance), or safety hazards (asbestos, electrical faults).

What It Costs

A standard building and pest inspection for a house costs $500-800 depending on property size and access difficulty. Apartments are cheaper, usually $400-600. Strata reports are separate and cost around $200-300.

If the inspection identifies concerns, you might need specialist reports — an engineer for structural issues, an electrician for electrical systems, a plumber for drainage problems. These cost extra, typically $300-800 per specialist.

That sounds like a lot, but compare it to the cost of discovering a $40,000 re-roofing job after you’ve bought, or a $25,000 termite remediation. The inspection cost is insurance.

Common Issues I’ve Seen

Termite damage in older homes. This is the big one. Sydney’s climate is termite-friendly, and timber-framed houses are vulnerable. I’ve seen termite damage that required $80,000 in repairs to structural timbers. The buyer had skipped the inspection to save time.

Waterproofing failures in apartments. Bathrooms and balconies that weren’t waterproofed correctly leak into walls and ceilings. The repairs often require removing and replacing tiles, which costs $15,000-30,000 per bathroom.

Roof problems. A roof that looks fine from the ground might have missing tiles, rusted valleys, or deteriorated flashing. Re-roofing a typical Sydney house costs $15,000-25,000.

Electrical systems in pre-1980s homes. Many older homes still have original wiring that doesn’t meet current standards. Full rewiring can cost $10,000-20,000.

Asbestos. Homes built before 1990 often contain asbestos in eaves, fences, bathroom walls, or under floor coverings. Removal is expensive and regulated. Budget $5,000-15,000 depending on extent and location.

The Negotiation Tool

A building inspection gives you leverage. If the report identifies $30,000 in necessary repairs, you can negotiate a price reduction, ask the seller to fix the issues before settlement, or walk away if the problems are too serious.

Without an inspection, you have no negotiating position. The contract price is the price you pay, regardless of what you discover later.

The Emotional Reality

Buying property is stressful. You find a place you like, you make an offer, it gets accepted, and you just want it to be over. Organising an inspection feels like an extra complication. What if the inspector finds problems? What if you lose the property while you’re waiting for the report?

I understand the psychology, but here’s the truth: if a property has serious problems, you want to know before you buy it. And if another buyer is willing to purchase without inspecting, they’re either taking a big risk or they know something you don’t.

Strata Inspections for Apartments

For apartments, the building inspection is only half the picture. You also need to review the strata records, which show:

• Financial health of the owners corporation
• Outstanding levies or legal disputes
• Planned major works (elevator replacement, facade repairs)
• Insurance claims history
• Minutes from recent meetings

A strata report costs $200-300 and can reveal expensive upcoming special levies or unresolved building defects that will become your problem.

When Timing Is Tight

Sydney’s market moves quickly, and sometimes you have 48 hours between offer acceptance and contract exchange. Building inspectors know this and offer fast turnaround services.

Most reputable inspectors can complete an inspection within 2-3 business days of booking. If you’re in a genuine rush, some offer same-day or next-day service for an additional fee.

Don’t skip the inspection just because timing is tight. Book it as soon as your offer is accepted and make the contract subject to a satisfactory building report.

Choosing an Inspector

Not all building inspectors are equal. Look for:

• Licensing (required in NSW)
• Professional indemnity insurance
• Membership in a professional body like the Australian Institute of Building Surveyors
• Experience with the type of property you’re buying (houses vs apartments, old vs new)

Ask your conveyancer or mortgage broker for recommendations. Estate agents also know which inspectors are thorough and which produce lazy reports, though their incentives aren’t always aligned with yours.

What Inspections Don’t Cover

Building inspections have limits. Inspectors can’t see inside walls, under floors (unless there’s access), or behind built-in furniture. They assess what’s visible and accessible.

They also can’t predict future problems. A roof might have five years of life left, or it might fail next winter. The inspector gives you probabilities, not certainties.

For high-value properties or complex buildings, consider additional specialist inspections — structural engineers, arborists (for large trees near buildings), pool compliance inspectors.

My Take

Every buyer I’ve worked with who skipped a building inspection and later regretted it said the same thing: “I didn’t think it was necessary” or “I didn’t want to delay the purchase.” Every buyer who did get an inspection said it was worth the cost, even when it found nothing serious.

The inspection doesn’t just identify problems. It gives you peace of mind. You know what you’re buying. You understand the maintenance priorities. You’re not lying awake at night wondering if the roof will hold up or the walls will crack.

For $500-800, that’s a reasonable trade. The cost of discovering major defects after settlement is financial and emotional, and it’s much higher than the cost of an inspection.

If you’re buying property in Sydney in 2026, get the inspection. It’s not optional anymore.
