Grant Ellis
Licensing & Compliance Researcher
Grant covers contractor licensing and compliance for BuilderBuzz, from the threshold question of whether you need a license to state-by-state requirements, reciprocity, timelines, and the bonding and insurance that come with them. He writes guides that explain not just the rules but how they fit together, and he sources every requirement to the state's own licensing board so readers get the real numbers, not a rounded-off version. His aim is to make a confusing, high-stakes process navigable, with the specifics a contractor needs to act.
