Violations & Fines
Operating without a license carries a $500 fine per offense under §645.160, and each procedure performed plus each day the shop keeps offering service counts as a separate offense. Licensed operators or establishments cited for other violations face escalating administrative fines of $250, $500, $750 and $1,000 for the first through fourth violation within two years (§645.180), on top of a warning, suspension of up to 90 business days, or revocation after a hearing before the Department Director (§645.170). Tattooing or piercing a minor without notarized consent is punished far harder: a six-month license suspension on the first offense alone (§645.170(F)).
