Interior designers who wish to use the designation "registered interior designer" must register each year with the Department of Consumer Protection.
Registered Interior Designer

The state does not regulate who may practice interior design.

By law, a “registered interior designer” is someone qualified by education, experience, and examination who:

1. identifies, researches, and creatively solves problems pertaining to the interior environment's function and quality;

2. performs services relative to interior spaces, including programming, design analysis, space planning, and aesthetics, using specialized knowledge of non-load-bearing interior construction, building systems and components, building codes, equipment, material, and furnishings; and

3. prepares plans and specifications for non-load-bearing interior construction, material, finishes, space planning, reflected ceiling plans, furnishings, fixtures, and equipment relative to the design of interior spaces to enhance and protect the health, safety, and welfare of the public (CGS § 20-377k).

Related Case
The state does not regulate who may practice interior design, but it limits a person's right to title or market themselves as a registered interior designer (Roberts v. Farrell, 630 F.Supp.2d 242 [2009]). By law, a person cannot use the title “registered interior designer” or otherwise indicate that he or she is a registered interior designer unless he or she (1) has registered as an interior designer with the Department of Consumer Protection (DCP) or (2) is an architect licensed in the state.
