Inspections

When is a defect actually a defect

Most building arguments are about permission, not about facts.

Owner Inspections · Box Hill 2765 · 2026-05-06

In short: A report that cites the tolerance turns an argument into a measurement.

Two questions, not one

What was built, and whether what was built sits inside an allowance. In practice it is only ever the second that gets argued.

Where the allowances come from

Your contract, the National Construction Code, the relevant Australian Standard and the Guide to Standards and Tolerances 2017.

Why citation matters

An item described as poor workmanship invites debate. Cited against a tolerance it becomes a measurement.

The honest grey area

Some things sit inside tolerance and still look wrong. A report that says so is more useful than one listing everything an owner dislikes.

Structural versus cosmetic

Every report makes the split explicit, because it decides what is worth pressing.

FAQ

Questions Box Hill owners ask about this

Does inside tolerance mean I accept it?

Within your contract, generally yes. Understanding that spares you a fight you were never going to win.

Who sets the tolerances in NSW?

The Guide to Standards and Tolerances 2017 covers most residential work, read with your contract and the Code.

What if a tolerance is cited wrongly?

Then the report and the guide can be put side by side, which is why items are cited rather than described.

Does a long cosmetic list serve any purpose?

No, but it should be labelled cosmetic. Two structural items lost inside eighty cosmetic ones serve no one.
