Who Owns the Plans

If the builder drew the plans, they may own the copyright. Without an assignment of that intellectual property, you may not be able to use the plans for future renovations, extensions or a rebuild.

Copyright can stay with the designer

The person or business that created the plans may own the copyright in them.

Paying for a build is not buying the IP

Paying for the house does not automatically transfer ownership of the design documents.

Assignment or licence matters

Check whether the contract assigns the copyright to you or grants a licence to use the plans, and for what purposes.

Future use can be affected

Without appropriate rights, you may not be able to reuse the plans for later work or a rebuild.

People realise too late

Most owners only think about this when they need the plans and the builder will not release them.

Questions to ask before signing

Who owns the copyright in the plans? Do I get an assignment or licence? Can I use the plans for future work? What happens to the plans if the contract ends?

The key lesson

Owning the house is not the same as owning the plans. Sort out the intellectual property position before you sign.

Before You Sign

This guide provides general educational information for South Australian homeowners. It is not personalised legal advice. The effect of any issue depends on the wording of your own contract, schedules, Special Conditions, plans, specifications and the facts of the project. A good builder and a well-understood contract should work together. Before committing to one of the largest financial transactions you may ever undertake, consider having the actual contract reviewed so you understand the obligations, notice requirements and consequences before they are tested on site.
