In Minnesota, if you are working with a licensed construction contractor they are required by statute to have all proposals, estimates, bids, quotes, contracts, purchase orders and change orders in writing. (Minnesota Statutes Section 326B.809) Sometimes we all get lackadaisical about how we transact business, but misunderstandings as to the scope of work and the cost of the work just bring headaches if things go bad. Don’t let that happen to you, get it in writing. Note, this provision applies to licensed residential contractors. In another post, I will discuss “who” those folks include.
