In order to obtain a demolition permit from the cities of Fremont, Newark or Union City, you will be required to contact Union Sanitary District. When you contact us, a Demolition Notification letter will be completed and sent directly to the appropriate city within two to three business days.

In order for us to complete the Demolition Notification letter, please have the following information available:

  • Type of structure being demolished
  • Address of structure
  • Owner information
  • Proposed new construction
  • Will the sewer lateral be used or abandoned?
  • Date of demolition (allow at least 2 to 3 weeks for our Collections construction crew to complete capping)

Our Collection Services department will call to verify that you are ready for the lateral to be temporarily capped or permanently abandoned. If you choose to reuse your existing lateral, you will be required to televise that lateral before connecting. USD requires capping so that debris will not get into our sewer lines when demolition begins.

Please contact us at (510) 477-7626 or (510) 477-7642 regarding any demolition questions.
