A commercial fire alarm permit is required for all new construction and build-outs as determined by the Building and Fire Departments. The Sudbury Fire Department requires that commercial fire alarm plans be submitted for review. During the rough wiring phase, please call the Sudbury Fire Department (978-443-2239) to schedule a preliminary inspection. Once the installation is completed, call to schedule a final inspection. Inspections are scheduled Monday through Friday between 9:00am and noon.
