Payment Information

NOTICE - February 9, 2021, 4:20pm
The City of Mountlake Terrace was notified that the company we use for online utility payments has been breached by ransomware which is why their website is down and cannot accept payments at this time. The city does not know how long their site will be down. Please read this news release for more information on the breach.

February 9, 2021, 10:15am
The city has been informed that our utility billing vendor’s website is down and cannot accept payments right now. We are trying to reach the company for more information. In the meantime, customers can drop off payments in the utility drop box at Interim City Hall parking lot (Redstone Building, 6100 219th Street SW) or contact your bank to set up online bill pay. If you have additional questions, you can contact our Utility Billing Department at or 425-744-6214. We will provide more information as soon as we can. Thank you for your patience! 

In Person

Utility payments can be made at the Interim Mountlake Terrace City Hall in two ways:

  1. Payments may be made in our drive-up drop box located outside of the Interim City Hall at the west side of the Redstone Building, by disabled parking. No cash in drop box please.
  2. Payments may be made to a staff member or simply dropped in the payment box on the counter inside Interim City Hall. Add your account number to your check, no envelope necessary. No cash in drop box please.
