IF I WANT TO SUBMETER, OR TRANSFER OTHER UTILITY COSTS TO THE RESIDENT, WHEN AND HOW SHOULD I DO IT?

If there is a general transfer of utility charges from the landlord to the tenant, the rental agreement must be amended. For a one-year tenancy, the agreement can only be amended on the tenancy anniversary date absent the tenant voluntarily agreeing to the amendment. For a month-to-month tenancy, the agreement can be amended on its original tenancy inception date in any month. Utility charges are not rent and, therefore, do not require three months prior notice to transfer, otherwise change, or increase. (RCW 59.20.060 (1)(a)(1)
