Kittitas (pronounced 'kit-i-tass') County is located in central Washington
State. It spans from the lush forested Cascade Mountains to the upper Yakima River Valley plains and
the Columbia River.
Prior to 1992, there were an estimated 6,300* rural residences and businesses
in Kittitas County. Addresses were established by route and box numbers and the
physical location of a residency or business was not referenced. In October 1992
Kittitas County began developing the current Rural Addressing Program which
established a permanent road name and number address.
The Rural Addressing Program was initiated in part by Washington State
Referendum Bill Number 42, which mandates that enhanced 911 (E-911) be in place
by December 31 1998. E-911 or Enhanced 911 is a North American
telecommunications based system. The E-911 system automatically associates a
physical address with the calling party’s telephone number, routing the call to
the most appropriate Public Safety Answering Point (PSAP) for that address. When
911 is dialed the system automatically displays the address and information to
the call taker immediately upon call arrival. This provides emergency responders
with the location of the emergency without the person calling for help having to
To obtain a physical address, applicants must submit an access and/or address
application to the Kittitas County Public Works Department along with any
associated fees. Addresses are established based on the following criteria:
Once an application has been submitted, Kittitas County Public Works has two
weeks from the date received to process and return the permit or to contact the
applicant for further information.
New approaches onto a county right of way are to be constructed and approved prior to the issuance of a building permit.
