About

Reno Ruler is an independent information site for Australian homeowners planning a renovation. It explains what drives the cost of kitchens, bathrooms, extensions, second storeys, granny flats, knock-down rebuilds and full refurbishments, and how to turn that into a budget range you can test against real quotes.

The site also summarises the rules that protect you: builder licensing, written contract requirements, deposit caps, cooling-off periods, home warranty insurance, the Australian Consumer Law and the dispute pathways in each state. Rules are written as of October 2026 and point to the official regulator so you can confirm the current figures.

What we do not do. We do not rank, review or recommend builders, and we do not publish testimonials or case studies. Cost figures are illustrative ranges built from stated assumptions, not quotes, surveys or market prices. We do not give legal, tax, engineering or financial advice. For a specific contract, dispute, structural question or tax position, speak to the relevant regulator or a qualified professional.

Roofing, heating and cooling, solar and batteries, leak repairs and window replacement are covered only briefly because they deserve their own detailed guides.
