All 50 states regulate tattoo facilities in some way, but each state has different rules, according to the American Academy of Miropigmentation. As of September 2014, New Jersey and Maine require AAM certification. As of May 2013, 45 states prohibit or limit the tattooing of minors under the age of 18 at tattoo facilities, according to the National Conference of State Legislatures
New Mexico requires a tattoo establishment to be supervised by a board-licensed tattoo artist as of September 2014, and facilities must pay a license fee. New York's Department of Health obligates tattoo artists be licensed in whatever studio they work. Tattooists in New York must wash their hands, wear clean gloves, wash the skin of the person getting the tattoo, utilize single-use needles and ink cartridges, and cover the new tattoo with a bandage.
With regard to tattooing minors at facilities, many states require the written consent of parents before a minor gets a tattoo. Other states, such as California and New York, make it a misdemeanor to tattoo anyone under 18 regardless of parental permission, according to the NCSL. In Arizona, it is a felony to administer a tattoo to anyone under 18 without written consent. In Idaho, children as young as 14 can get tattoos with written parental consent. New Hampshire requires tattoo parlors to keep these written records on file for at least seven years, and Kansas requires written consent to be kept on file for five years.
