MI HB5142

Creates a new licensing system for interior designers in Michigan, establishing an Interior Design Board to oversee the profession and issue licenses beginning January 1, 2027

Requires interior design license applicants to complete an accredited interior design program, a supervised work experience program, and pass the National Council for Interior Design Qualification (NCIDQ) examination

Defines "practice of interior design" as nonstructural interior construction work including space planning, egress design, code compliance review, and interior finishes—but excludes structural, mechanical, electrical, plumbing, and fire safety system modifications

Mandates 12 hours of continuing education annually for license renewal and requires licensed interior designers to sign and seal interior technical submissions with a reproducible seal

Exempts architects, employees working under supervision, consultants, individuals designing for private use, and those performing decorative work (paint, wallcoverings, furniture selection) from licensure requirements
