JEFFERSON CITY, Missouri (July 13, 2026) – Missouri has become the latest state to expand practice rights for qualified interior designers through updated legislation. Senate Bill 1233 modifies the state’s existing Title Act to allow qualified, licensed interior designers to practice independently and sign and seal their own documents. The bill was passed by the Missouri Legislature on May 28, 2026, and signed into law by Missouri Gov. Mike Kehoe on July 13, 2026. 
 
The bill makes Missouri the latest state to establish or modernize interior design legislation, joining Alaska, Idaho, and Utah in 2026; Oklahoma, Nebraska, and Pennsylvania in 2024; Iowa in 2023; Wisconsin and Illinois in 2022; and North Carolina in 2021. 
 
The modernization of Missouri’s statute represents the culmination of a multi-year advocacy effort led by the Missouri chapters of the American Society of Interior Designers (ASID) and the International Interior Design Association (IIDA), with support and guidance from The Consortium for Interior Design. The Consortium is a collaborative advocacy group comprising ASID, IIDA and the Council for Interior Design Qualification (CIDQ) that works to advance recognition and reasonable regulation of the interior design profession
 
“This legislation represents an important step forward for Missouri’s interior designers and the communities they serve,” said Khoi Vo, president and chief executive officer, ASID. “By recognizing the qualifications and expertise of interior designers, Missouri is supporting a more efficient and collaborative design process while ensuring consumers have access to professionals who meet rigorous education, examination and experience standards.”
 
SB 1233 updates the registration process for interior designers through Missouri’s Division of Professional Registration and establishes a framework for recommendations from the Interior Design Council to the Missouri Board for Architects, Professional Engineers, Professional Land Surveyors, Professional Landscape Architects, and Licensed Interior Designers.
