AZ HB2309

Adds interior designers to Arizona's state board of technical registration by changing the chapter heading to include "interior designers" and requiring one registered interior designer board member beginning January 1, 2017.

Establishes qualifications for interior designer registration including being at least 18 years old, passing a nationally recognized written examination, completing at least 40 semester hours of interior design coursework, and possessing 3,520 hours of diversified practical interior design experience.

Requires interior design documents filed with state or local building departments for building permits to bear the seal of the engineer, architect, or registered interior designer who prepared or approved them.

Allows nonregistrants to design interiors of detached single-family dwellings or commercial spaces without registration if the work does not involve code compliance issues requiring sealed plans or building permit approval.

Makes it a Class 2 misdemeanor to advertise or display a card, sign, or other device indicating someone is a registered interior designer unless the person holds that registration.
