Contractor licensing and insurance guides

19 guides · 4 pillars, verified 09 2026

Written for the person who has to file the paperwork. Where we could read a fee, a bond amount or a threshold from the board that sets it, it is here with the date. Where we could not, the page says so instead of guessing.

The guides follow the same four pillars as the rest of the site. State requirements explains who issues a license and when the law demands one; licensing process walks experience, application, exam and renewal; bonds and insurance covers the bond a board demands and the cover a general contractor, an owner and the state each ask for; and trade licenses follows the electrical, HVAC, plumbing and roofing ladders. If you need a number for one state rather than an explanation, go to the jurisdiction sheets; if you need to work something out, the tools run in your browser and print.
