Understand your building’s requirements
An inspection. Clear documentation. Your next step.
We work with Brooklyn landlords, homeowners, property managers, and co-op and condo boards to plan gas piping inspections and explain the findings.
LL152 generally requires gas piping inspections every four years. One- and two-family homes and other R-3 properties are exempt; confirm the actual building classification and DOB record before assuming your property is excluded.
Use DOB’s property lookup and inspection guidance to check applicability. If gas piping exists but service is disconnected, ask about the specific documentation requirements for that situation.

Exposed piping & common areas

Conditions needing attention
We look for issues such as deterioration, unsafe connections, and leaks, then explain the findings and any required action.

A little clarity helps
Your questions, answered.
Have a question about your property? Talk with our team.
Who can perform a Local Law 152 inspection?
A NYC Licensed Master Plumber, or a DOB-registered journeyman plumber with the required training working under the direct and continuing supervision of a Licensed Master Plumber. A general trade certification alone is not the same as DOB journeyman registration.
Does A Good Plumber submit my DOB certification?
We perform the inspection and prepare the inspection documentation. The building owner completes the certification submission in DOB NOW. Our Final Filing Guide explains the signing, payment, and submission steps.
What if my building does not contain gas piping?
If LL152 applies to the property, DOB requires a no-gas-piping certification. After it is accepted, further periodic LL152 inspections are not required unless gas piping is installed. Confirm your building’s status with the DOB guidance.
Are individual apartments included in the periodic inspection?
The required scope covers exposed piping and the leak survey in specified common areas, up to tenant spaces. It does not include gas piping inside individual tenant spaces. See DOB’s inspection-scope FAQs.
What happens if the inspection finds a problem?
We explain the findings, any reporting requirements, and the repair or follow-up certification steps. If corrective work is needed, our gas piping team can discuss the scope. Unsafe conditions require immediate action.
Can you help organize inspections for several buildings?
Yes. Share the property addresses, community districts, and inspection records. We can discuss scheduling and documentation for the portfolio; each owner remains responsible for the required certification submission.
Inspector qualifications: NYC Administrative Code §28-318.3.1. Requirements and portal procedures should be checked against current DOB guidance.
