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 certification 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. - Is the LMP actively licensed with the NYC Department of Buildings?
You can verify by searching their name, business name, or license number. - Has the LMP been subject to any DOB disciplinary actions?
This can also be verified through DOB records.
Inspection & Compliance Process
- Will the inspector help resolve repairs and file the final GPS2 certification?
If not, you may need to hire a separate LMP to complete the process. - Did the inspector explain the requirement to notify DOB before 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
- If not required, 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
- Will the inspector file the GPS2 form through the official DOB portal?
They should also provide the DOB confirmation receipt. - Will you receive both paper and digital copies of GPS1 and GPS2?
These records must be retained for 10 years.

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.
