Field impact

What matters on a fire alarm project

Do not assume a paper submittal is acceptable; New Haven directs construction permits to its online process.
Because the public site does not clearly spell out a dedicated fire-alarm submittal package, contact the Fire Marshal before preparing the final submission set.
Keep the city permit record number with the project so Fire, Building, and trade closeout can be coordinated.

Pre-submittal

Contractor checklist

Open the current online construction-permit workflow.
Call the Fire Marshal’s Office to confirm fire-alarm plan format, quantities, and fee.
Upload/submit the exact documents requested for the project.
Confirm acceptance-test scheduling and closeout requirements before the job is ready for inspection.
