SGM Engineering is a New York City Department of Buildings–approved Class 2 Special Inspection Agency with over 50 certifications. We perform mandated special inspections for mechanical systems, energy code compliance, and DOB sign-offs across commercial and institutional projects throughout NYC.


Experience That Strengthens Inspection Oversight:
With over 25 years of mechanical engineering expertise, our inspectors understand design intent, field execution, and DOB compliance requirements — allowing us to identify discrepancies early and streamline approvals.
With nearly three decade of mechanical engineering experience, our inspectors understand intent behind drawings — not just what is visible in the field.
We identify discrepancies before they become violations, preventing delays and costly rework during DOB review.
Our inspection reports are structured for DOB compliance, ensuring seamless approvals and reduced administrative friction.
