General information, not legal advice.
License thresholds and permit rules change, and your city or county enforces the permit. Local rules vary. Anything this research could not confirm is shown as “Check with your local building department,” not as a rule you can rely on.

Home Improvement Registration for residential home-improvement work over $7,500; Residential Building Contractor license over $75,000 (search summary of the LSLBC Blue Book; verify the 'or more' vs 'over' wording). Electrical/plumbing/HVAC have separate requirements.
