Local Law 152 · Filing

GPS1, GPS2 and the DOB filing, step by step.

Local Law 152 compliance is a paperwork trail as much as an inspection. This is the order it happens in and the deadlines that apply.

1. The inspection

A Licensed Master Plumber, or a qualified individual working for one, inspects the building's exposed gas piping from the point of entry, including public spaces, hallways, meter and boiler rooms. Piping inside individual apartments is not part of it.

2. GPS1 report to the owner, within 30 days

The plumber gives the owner the Gas Piping System Periodic Inspection Report (GPS1), listing any conditions that need correction.

3. GPS2 certification to DOB, within 60 days

The plumber submits the Gas Piping System Periodic Inspection Certification (GPS2) to DOB, which DOB now takes through DOB NOW. It has to reach DOB by your community district's December 31 deadline.

4. Corrections, within 120 or 180 days

If the GPS2 shows conditions requiring correction, a new certification signed by the Licensed Master Plumber who did the inspection must reach DOB within 120 days of the inspection, stating the corrections are done. If the original filing said more time was needed, the window is 180 days.

5. Keep the records

Keep the inspection report and certifications on file. DOB can ask for them, and the next cycle's plumber will want to see them.

Questions

Short answers.

  • Who submits the filing, the owner or the plumber?

    The Licensed Master Plumber who performed the inspection signs and seals the certification. In practice the plumber files it, and the owner should get a copy.

  • How do I check whether my building has filed?

    DOB publishes an LL152 compliance search by address and a downloadable list of properties on its gas piping inspections page.

  • What if the deadline has already passed?

    Inspect and file as soon as you can. DOB lists a $5,000 penalty for not filing by the due date, and the building stays out of compliance until it files.
