Because of RCW 35A.40.200, the competitive bidding requirements of RCW 35.23.352 are applicable to contracts executed by a city operating under the optional municipal code when engaged in making public improvements or performing public works; however, these requirements are not applicable to the contracts of such a city for professional or personal services such as those of an insurance broker.
Unless restricted by the provisions of it own charter, a code city may, but is not required to call for bids on real property owned by it before selling such property either to a private party or to any other purchaser.
Under RCW 35A.06.030, a city which previously adopted the optional municipal code together with one of the plans of government thereby authorized for noncharter code cities may change to another plan authorized for noncharter code cities any time after one year from the date of becoming a noncharter code city.
