Do I need a contractor license for this project in my state, and what does it take to get one? Every US state handles general contractor licensing differently: some require a state license for any construction work, others only above a dollar threshold ($1,000 in Arizona, $10,000 residential in Alabama, $100,000 commercial in Alabama), and some have no state-level license at all (municipal only). One record per license type per state, sourced from the state's licensing board. Answers 'do I need a contractor license in Florida', 'what is the minimum project size for a contractor license in Alabama', 'general contractor license requirements by state', and 'how much is a contractor license bond'. New Jersey added a formal licensing system effective February 2026; Montana transitioned from registration to licensing in 2026. The assembled versions on page one are all from insurance lead-gen sites (nextinsurance.com, insureon.com) selling general liability to contractors. Extends the electrician-licence-progression-by-state pattern to general contractors.
Provenance — what every record carries
Every record carries source (the URL the value was read from) and
source_quote (a verbatim quote from that page stating it). A value you
cannot check against its page is indistinguishable from an invented one;
these can all be checked. Each record is also individually addressable on
the canonical site at its url.
Licence position
Facts extracted from state licensing board websites, with attributed quote and link back. Licensing requirements are public regulatory facts. No source carries a restrictive notice.
Facts are not copyrightable; what this dataset takes from each source is a fact plus a short attributed quote linking back to the page that states it.
