It is impossible for an interior design law to determine the scope of practice. The exemptions contained within the architects and engineers practice acts that determine the minimum standard for practicing architecture or engineering. Within both practice acts there are exemptions (CBPC Sections 5537, 5538, 6737.1 & 6745) that have been in place since 1939, which spell out the work that is exempt from the requirements of engaging an architect or engineer to oversee the design. The scope of practice for interior designers cannot expand beyond the limits of those exemptions codified into law.
