What is the price difference between a building designer and a registered architect?

There is no standard price difference, and any typical figure would quickly go out of date. Fees depend on the size and complexity of the home, the site, and how much of the service you engage them for, for example concept design only, approval drawings, construction drawings, or contract administration. Ask each for a written fee proposal that states exactly what is and is not included, how extra work is charged, and what happens if the design changes. Compare scope as well as price. The regulation of the title architect and of building designers differs by state, so check the registration of anyone you engage with the relevant state board or regulator.

In MyBuildHub: record each fee proposal as a consultant cost line in your budget, and keep the signed agreement in your project documents.

Check yourself: your state architects registration board and your state building regulator.
