Need suggestion on how to evict the tenant legally

[Charles D.]

My wife has a house in Tacoma Washington. She is managing the property herself 1st time. My wife wants to check the expiration date of the smog and CO detector. The tenant will not allow her to do to the house to check it. What can my wife do? Also the tenant has been late on the rent and the contract will expire on Nov this year. My wife does not want to renew the contract with her after it expires. What are the steps to evict her legally? Thanks in advance
