Reminder about Submittals, cont.

• Submittals should always go to Deb Bruce in her office or in the tray across the hall from her office when she is not in her office.

• Please do not leave them on any of the FPB personnel’s desk. If you would like confirmation of receipt you can check the website .

• If you don’t see the submittal logged on the website, typically within a day unless Deb is out of the office for an extended period, then follow up with a call or email.

Reminder about Submittals, cont.

• Responses/resubmittals will include specific instructions on how the information should be resubmitted. You may always submit hard copies of resubmittals to the Fire Prevention Bureau at 2715 Dean Avenue.

• If the action required specifies a hard copy that is how the response should be sent. Typically electronic plans can’t be reproduced/reviewed as required.

• If the action specifies electronic submittal is acceptable, e.g. calculations or clarifications, they should be emailed to :

• firedept@dmgov.org

• If you can’t confirm whether or not you received a permit, please check the website prior to calling for a test or inspection.
