Business Licenses

City of Mountlake Terrace Business Licensing
The City of Mountlake Terrace requires all businesses located within the city limits, or those conducting business within the city limits, to be licensed with the city. 

Mountlake Terrace participates in the State Business Licensing Service partnership. This is a combined licensing system through the Department of Revenue, making it easier, for most businesses, to connect state and local requirements in one annual transaction. For fast service, apply for a business license at the Department of Revenue (DOR) business page.  Below are descriptions of licenses available in the City of Mountlake Terrace. A list of City requirements and fees are also located on the Department of Revenue website.

Home Occupation Licenses
In order to operate a business from your Mountlake Terrace residence, and prior to obtaining a business license, a Home Occupation permit approval may be necessary. To determine whether your business requires a Home Occupation approval, please contact the Planning Department. After the Home Occupation Application is submitted to our Permit Center at City Hall and approved, you will need to apply for a City Business License through the Department of Revenue business page. Any additional questions regarding the home occupation process can be directed to the Permit Center.
