Not all Local Law 152 inspections are the same.
Hiring the wrong company can lead to:
- Invalid inspections
- Filing issues
- Costly violations
- Delays in compliance
If you’re a building owner or property manager in NYC, doing proper due diligence before hiring an inspector is critical.
What “Due Diligence” Means for Local Law 152
Local Law 152 is not just an inspection.
It’s a process that includes:
- Inspecting exposed gas piping
- Proper documentation
- Accurate building identification (Block, Lot, BIN)
- Filing accurately with the NYC Department of Buildings
- Ensuring compliance with DOB requirements
If any step is handled incorrectly, it can lead to violations even if the inspection itself was completed.
Due Diligence Questions to Ask Before Hiring an LL152 Inspector
Before hiring a Local Law 152 inspector, you should be asking the right questions.
Qualifications & Licensing
- Is the inspector a Licensed Master Plumber (LMP) or a qualified employee of one?
If not an LMP, they must meet DOB requirements for experience, training, and Worker Wallet Credentialing and be able to provide proof.

Inspection & Compliance Process
- Will the inspector help resolve repairs and file the final certification of corrected conditions?
If not, you may need to hire a separate LMP to complete the process. - Did the inspector explain the requirement to notify DOB 2 days in advance of the inspection?
As of early 2026, inspectors must submit notice to DOB at least 2 days before the inspection.
If this is not done, the inspection may be considered invalid. - Was the scope of the inspection clearly explained ahead of time?
A qualified inspector should explain the process and possible outcomes before starting.
Training & Experience
- Although not required for an LMP, has the LMP still completed the DOB-approved 7-hour Local Law 152 training?
This shows a higher level of commitment to compliance and best practices.
Insurance & Risk Protection
- Does the inspector carry both General Liability (GL) and Professional Liability (E&O) insurance?
GL alone does not cover inspection errors. E&O is critical. - Will they provide proof of insurance?
Always request documentation before the inspection begins.
Filing & Documentation
- Is the Inspector Fluent Using the New Paperless Filing Process?
As of July, 27th 2026 the LL152 filing process migrated to DOB NOW: Safety. - Did the inspector explain that you will have to also log in to DOB NOW and attest to the accuracy of the filing ?
As of July, 27th 2026 the owner of the building or their authorized representative has to provide attestation in order for the filing process to be complete
Accuracy & Compliance Details
- Has the inspector confirmed your building’s inspection due date?
They should verify your subcycle and advise on extensions if needed. - Is the leak survey conducted using a PSC-approved gas detection device?
Equipment must meet NYS Public Service Commission standards.
