Licensed Special Inspectors in NYC
DOB-registered and IAS-accredited special inspectors serving all New York City boroughs. Chapter 17 inspections for structural steel, concrete, masonry, anchors, fireproofing and more — backed by a Licensed Professional Engineer with 28+ years of NYC experience.
Who Are NYC Licensed Special Inspectors?
Licensed special inspectors in NYC are qualified professionals employed by a Registered Special Inspection Agency who provide mandatory, independent verification of critical construction activities as required by New York City Building Code Chapter 17.
Unlike routine building department inspectors, licensed special inspectors are retained by the property owner and operate during active construction — verifying structural steel connections, concrete placement, masonry installation, post-installed anchors, fireproofing application, and other code-defined activities as they happen.
Each inspector must hold certifications appropriate to their discipline and work under the supervision of a Licensed Professional Engineer (PE) registered with the NYC Department of Buildings. Our agency maintains full compliance with 1 RCNY 101-06, the NYC DOB rules governing Registered Special Inspection Agencies.
Every project begins with a TR1 designation filing through DOB NOW that formally identifies the inspection agency, scope of work, and responsible PE. We manage this entire process on your behalf — from filing through final signoff.

FAQs: Licensed Special Inspectors in NYC
Who are licensed special inspectors in NYC?
Licensed special inspectors in NYC are qualified professionals employed by a Registered Special Inspection Agency who perform mandatory third-party inspections required by NYC Building Code Chapter 17. They must hold discipline-specific certifications (AWS CWI for welding, ACI for concrete) and work under a Licensed PE.
What does a licensed special inspector do?
They verify that critical construction work — structural steel, concrete, masonry, post-installed anchors, and fireproofing — is performed per approved construction documents, NYC Building Code Chapter 17, and referenced standards. They issue daily inspection reports and document all deficiencies.
How do I hire licensed special inspectors in NYC?
Contact a DOB-registered Special Inspection Agency. They'll review your scope, identify applicable Chapter 17 categories, file a TR1 designation through DOB NOW, and assign qualified inspectors. The property owner retains the agency directly.
Are special inspectors different from DOB inspectors?
Yes. DOB inspectors are city employees performing milestone checks. Licensed special inspectors are private professionals retained by the owner, providing continuous or periodic third-party oversight of specific construction activities that DOB inspectors do not perform.
What is the TR1 form for special inspections?
The TR1 is the Statement of Special Inspections designation form filed through NYC DOB NOW. It identifies the Registered Special Inspection Agency, responsible PE, and all applicable Chapter 17 inspection categories for a project. It must be filed before special inspection activities begin.
