Home improvement disputes are almost never about craftsmanship; they are about scope, sequence, and money that moved in the wrong order. This article explains what a residential construction contract has to say, why the payment schedule is the single most protective term in it, and how the mechanics lien system can leave a homeowner paying twice for the same work. It covers licensing, permits, change orders, defects, and the moment when a job has been abandoned rather than delayed. It follows two fictional kitchen renovations with identical budgets and very different endings. The practical thesis is that a homeowner's leverage is entirely front-loaded, and almost all of it is spent before the first payment.
