Editorial policy
Our guides exist to help buyers plan a build and ask builders better questions. These are the rules we write them by.
Last reviewed
Independence
Builders cannot pay to be mentioned in, shape or review our guides. Commercial relationships are described on our How we make money page.
Sources and review
Prices, timelines and rules in a guide come from builder price sheets, quotes made through the site, and official sources such as health departments and fire codes. Each guide shows the date it was last reviewed, and we review every guide at least once a quarter.
Rules on permits, hoods, propane and vehicle registration differ by state and city. Our guides explain what to ask; your local authority's answer is the one that counts.
How we use AI
We may use AI tools to draft outlines or summarise sources. A person on our team checks every fact, figure and claim before anything is published, and is responsible for it. Images labelled as AI-generated are illustrations, not photos of real builds.
Corrections
If you find a mistake, tell us through the quote or builder forms and we will fix it and update the review date on the page.
