They apply to any registered contractor, so use them to compare anyone you're thinking of hiring. - **A written contract.** Work over $1,000 needs one, with the work, materials, total price and payment schedule ([M.G.L. c. 142A, s. 2](https://malegislature.gov/Laws/GeneralLaws/PartI/TitleXX/Chapter142A/Section2)). - **A deposit limit.** No more than one-third of the price, or the actual cost of special-order materials if that's higher. [How the deposit rule works](https://magnoandco.com/blog-contractor-deposit-massachusetts) - **Time to cancel.** If you sign at home, you have until midnight of the third business day to cancel in writing ([M.G.L. c. 93, s. 48](https://malegislature.gov/Laws/GeneralLaws/PartI/TitleXV/Chapter93/Section48)). - **Changes in writing.** Any change to the contract must be written and agreed by both sides. [What a good change order includes](https://magnoandco.com/blog-construction-change-order) - **The state Guaranty Fund.** If you win an award or judgment against a registered contractor and can't collect it, you can apply for up to $25,000 of your actual loss. It's for your primary home, and you lose this protection if you pull the permit yourself.
