The Interior Design Profession
The interior design professional plans and designs interior residential, institutional, and
commercial building spaces. More specifically, interior designers prepare and administer design
documents, including drawings, schedules, and specifications, which pertain to furnishings,
layouts, fixtures, cabinetry, lighting fixtures, finishes, materials, and interior construction not
materially related to or materially affecting building systems. The work must comply with
applicable laws, codes, regulations, and standards. The scope of work performed by an interior
designer may not be construed as authorizing the practice of architecture or engineering as defined
under Maryland law, but interior designers may be involved in the movement of nonload-bearing
walls as long as there is no material impact on building systems. The practice includes access and
egress planning and barrier-free planning for individuals with disabilities. Knowledge of
building codes and standards and knowledge of product properties, including flammability,
toxicity, slip-resistance, indoor air quality, ergonomics, illumination, and acoustics, are also
aspects of the profession.
Certified interior designers in Maryland may also perform “design coordination” for a
project or portion of a project as long as they hold a current certificate issued by the board and have
adequate experience and knowledge to achieve the objective of the project or portion of the project
being coordinated. Design coordination is the review and coordination of services provided by
certified interior designers, architects, professional engineers, landscape architects, and
professional land surveyors. Certified interior designers must state in each of the interior design
documents that the document is not an architectural or engineering drawing, specification, or
design and is not to be used for construction of any load-bearing column, framing, wall, or
structure.
Although the terms “interior design” and “interior decorating” are often used
interchangeably, the two practices differ. Interior designers create functional building spaces,
while interior decorators focus more on furnishings, color schemes, fabrics, etc. NCIDQ
emphasizes that one primary difference between the two professions is that interior designers are
responsible for the elements of design that affect the health, safety, and welfare of the public.
NCIDQ offers the example that, while an interior designer can evaluate wall finishes based on
criteria such as durability, acoustic properties, flame retardancy, and toxicity, an interior decorator
can evaluate finishes based only on color, style, and texture.
NCIDQ is the national organization setting standards for interior design professionals.
Passing the NCIDQ examination is required for certification as an interior designer in Maryland.
Most states that regulate the interior design profession, including Maryland, are members of
NCIDQ.
