Exempt services: Landscape Architects

State laws recognize that certain areas of expertise are common to professionals other than landscape architects. For a list of the exemptions, see RCW 18.96.220: Application — Professions and activities not affected.

Licensed and recognized professions

Application of the law does not prevent the practice of architecture, naval architecture, land surveying, engineering, geology, or any recognized profession by individuals not licensed as landscape architect.

Contractors and technical specialists

Application of the law does not prevent registered contractors from engaging individuals who are not landscape architects to provide plans where a stamped plan is not required. The construction, alteration, or supervision of sites by contractors or superintendents employed by contractors or the preparation of connected shop drawings is exempt.

The law does not restrict biologists from doing biological work on natural site areas. Other unlicensed technical specialists may be allowed to perform design work that does not require a licensed professional to stamp the plans.

Residential design work

Application of the law does not prevent owners or any other persons from doing design work or preparing construction documents or shop drawings on a residential project that does not fall under the jurisdiction of a local permitting agency or otherwise affect the health, safety, and welfare of the public.

Health and safety is affected if the work included has the potential to put the public or landowner at risk.
