Fire Sprinkler Design and Installation in New York City
FDNY-Approved Engineering, Installation & Acceptance Support
Fire sprinkler system design and installation in New York City is a regulated construction activity subject to FDNY and Department of Buildings (DOB) oversight. Compliance requires more than installing pipe and heads—it demands engineered design, plan approval, code-compliant installation, and successful acceptance testing.
County Fire Inc provides FDNY-approved fire sprinkler design and installation services to ensure systems meet NYC Fire Code, Building Code, and NFPA 13 requirements from initial concept through final approval.
Our approach is structured around how FDNY and DOB evaluate sprinkler systems during plan review, inspections, and acceptance testing, not generic design templates.
