Which property documents should you actually keep?

Ask ten property owners where their building plans are and you will get ten different answers: a drawer, a shoebox, an old email thread, the builder's office, or a shrug. The paperwork usually exists. It just isn't anywhere useful when someone finally asks for it.

The moments that ask for it are rarely convenient — an insurance claim, a dispute with a trade, a bank valuation, a buyer's conveyancer working to a deadline. That is the wrong time to discover a document is missing.

Here is the short list actually worth protecting.

1. Plans and permits

Architectural drawings, engineering plans, the building permit and the occupancy certificate. These are the hardest documents to reconstruct and the ones most often requested. If a council, insurer or buyer questions whether work was approved, this is the paperwork that answers it.

2. Certificates for anything that could hurt someone

Electrical safety certificates, plumbing compliance, gas fitting, waterproofing, pool fencing, smoke alarm compliance. These exist precisely because someone may need to prove the work was done to standard — often years later, and often when liability is being decided.

3. Warranties, with proof of what triggered them

A warranty on its own is close to useless. A warranty plus the invoice, the installer's details and the install date is enforceable. Keep the set together or don't bother keeping any of it.

4. The insurance trail

Your current policy schedule, yes — but also prior schedules and any claim correspondence. When a claim gets difficult, the argument is usually about what was covered at the time, and that means the older documents do the work.

5. Renovation and maintenance history

Quotes, invoices, scope documents, before-and-after photos. This is the record that turns "we upgraded the bathroom" into a documented improvement — which matters for valuations, for capital gains calculations, and for convincing a buyer that the work was done properly.

What you can let go of

Utility bills older than a couple of years. Duplicate copies of the same certificate. Marketing brochures from the original sale. Delivery dockets. If a document can be reissued in a phone call, it does not need archiving.

The part most people get wrong

Keeping documents is not the hard part — finding them is. A folder of 300 unnamed PDFs is not a record, it is a search problem you have deferred to your future self, usually on a deadline.

What makes a set of property documents genuinely useful is structure: each document filed against the property it belongs to, labelled with what it is and when it was issued, and retrievable by someone who is not you. A conveyancer, an insurer, a buyer, or your family.

That is the problem House Spek exists to solve — one organised record per property, ready before anyone asks for it.
