Roughing + Finishing

  • Altered Standpipe Systems.  An LMP or LFSC must conduct hydrostatic pressure testing.
  • Removing Stories.  An LMP or LFSC must conduct hydrostatic pressure testing before work begins.
  • All standpipe and sprinkler work must have a Special Inspection; the Special Inspector must be named at the time of permit using an online submission form.
  • Fire pumps are not permitted in spaces that have gas piping, appliances and equipment.

  • The installation of post-installed mechanical anchors, adhesive anchors and screw anchors complying with Table 1704.32.
  • Special inspection shall include verification of compliance with the approved construction documents and standards.

*The Special Inspection Agency need not witness the hydrostatic pressure test when such test is witnessed by DOB Plumbing Inspector.*

Required Standpipe Inspections

Department inspections are required at various stages of completion, as well as at the final completion. Based on the project scope of work, the following sprinkler inspections may be required:
  • Underground Piping. Bedding, pitch, materials, protection, flushing
  • Roughing Work.  Piping, valves, components, size, location, materials, hangers
  • Test. Hydrostatic, flow, Dry Pipe Valve, Fire Pump, and controls - Painting: where the project work requires a hydrostatic pressure test, all painting shall be completed prior to such test
  • Finishes.  Painting, escutcheons, signage, labeling, chaining of valves, and central station
  • Final Inspection and Sign-off.*  Must be performed at the completion of all work and the system is active. Contractor must check for submission of all Special Inspection reports prior to completing a Final Inspection for project’s sign-off.

*Contractors have the option to self-certify standpipe inspections.*

Contractor Self-Certification of Plumbing Inspections

For standpipe work, Contractors have the option to either require a Department Inspection or submit a self-certification of the completed work. The Contractor must submit a notice of intent to self-certify, with the dates of these self-certified inspections to the Department, (online inspection request) and follow-up with the submission of results for self-certified inspections (online inspection results).

The Standpipe Enforcement Unit conducts a random audit of all self-certified notices to ensure compliance of inspected work with Code and regulations.
