Which home inspection, and when

People ask whether they need a home inspection. The useful question is which one, and at what point. This is a plain-English reference to the 16 occasions on which somebody commissions one — what the standards actually require, what the report will and will not say, and why the window you choose decides how much the findings are worth.

The occasions people ask about most


Every page answers the same four questions: is this the ordinary inspection or something else, what does the standard actually require, what will the report say, and what do you do with it before the window closes.

Two categories

One word, doing far too much work

A four-point for an insurer, a phase inspection during framing, a move-out condition record and a buyer's inspection have almost nothing in common except the noun. Only three of the 16 occasions here call for the ordinary product unmodified.

Category one

Buying a Property

From before you offer through to the final walk-through. What you find early is negotiable and what you find late usually is not, so the consequential decision is when, rather than whether.

Category two

Owning & Selling

Commissioned against a warranty deadline, an insurance policy, a tenancy or a fiduciary duty rather than a sale — which changes who the report is actually written for.

Pre-listing Inherited

The thing most buyers miss

Every remedy in a property transaction has an expiry date

The option period. The inspection contingency. The builder's one-year workmanship warranty. The deposit statute's deadline for a move-out statement. Miss the date and the merits stop mattering.
