What is the preferred consultant program?

The preferred consultant program offers permit applicants the option of choosing a consultant from lists the Department of Permitting maintains of preferred consultants, individuals with a proven track record of high quality work in King County.

The Permitting Department developed the preferred consultant program in 2004 to make the permitting process more efficient and less costly, as quality permit application submittals can result in less permit review time and fee savings for customers.

Initially, preferred consultants were identified for critical areas review. In 2005, the program was expanded to cover site engineering and drainage review for single family homes.

Short Plat consultants added in 2007

In fall 2007, short plat applications were added to the program. The Permitting Department will identify consultants for short plat, in addition to residential, applications.

All preferred consultants in the program, by having met established criteria, give assurance to customers and Permitting staff that the consultant will make a quality permit application submittal.

The program also benefits permit customers by providing easy access to a pool of proven consultants, while benefits to consultants are increased visibility and a marketable certification.

Permit applicants still have the option of choosing a private consultant who does not participate in the Permitting Department preferred consultant program.
