Provides that, at least annually, the secretary of state shall search the residential addresses of all voter registration records in the voter registration data base for major public building addresses throughout the state. For purposes of this subsection, "major public buildings" includes city, county, state, and federal administrative buildings, courthouses, and police stations.

Requires that, for each search result, the secretary of state shall determine whether the voter is properly registered at the major public building under a lawful program that permits the voter to use a nontraditional address as his or her residential address, such as the address confidentiality program as defined in chapter 40.24 RCW.

Provides that if it appears that the voter has improperly listed a public building as a residence for purposes of voter registration, the secretary of state shall send notice by certified mail to the voter of the apparent improper residential address. The notice shall provide that the voter must respond within thirty days of the date of the notice by providing the secretary of state with: (1) The voter's actual residential address; or

(2) Evidence that he or she is properly registered at the major public building. The notice shall also advise the voter of the penalties for providing false information on an application for voter registration.

Provides that, if the voter fails to respond within thirty days to the secretary of state's satisfaction, the secretary of state shall forward a copy of all relevant information to the prosecuting authorities.
