Information, not professional advice

Our guides are research and opinion to help you choose equipment. They are not engineering, electrical, or legal advice. Snow-load ratings, BTU math, and permit notes are starting points: confirm structural, electrical, and permitting decisions with the manufacturer and a qualified local professional before you build.
