Choose the Correct Filing Route, Clear Review and Close Your Lowell Permit
Lowell does not use OpenGov for building permits. The city uses Munis Citizen Self Service, commonly called CSS, for selected online applications, permit searches, document uploads, payment and inspection-result viewing.
New construction and remodel or alteration applications must be filed in person. First-time online applicants should contact Development Services before applying so staff can identify and link the correct Customer ID.

Set Up CSS and Avoid an Unlinked Application
Contact Development Services first
Email buildingpermits@lowellma.gov or call 978-674-4144. Ask staff to identify the correct Contractor or Customer ID.
Create the CSS account
Use your complete email address as the user ID. Save the username and password securely.
Link the correct CID

Do not create an online new-construction or remodel/alteration application. Those categories must be filed in person.

Upload all documents as PDFs
Missing uploads prevent interdepartmental reviews from being assigned and can delay the application.
Save the application reference number

Wait for formal issuance
Pay only after notification. Do not begin work until the permit has been issued and the permit image or paperwork is available.
