Which System Configuration
Does Your Building Need?
The right sprinkler configuration depends on occupancy, building height, and water supply — not a default template. County Fire runs the hydraulic calculations to determine the right configuration before designing anything.
Pipes stay filled with pressurized water at all times, giving the fastest possible response when a head activates. Simpler mechanically and generally lower cost than dry-pipe, wet-pipe is the default choice for any heated, occupied building.
Required wherever freezing is a risk — parking garages, loading docks, and unheated storage. Pipes hold pressurized air until a head activates, which requires air compressor equipment and adds mechanical complexity most heated spaces don't need.
When city water pressure alone can't meet the hydraulic demand of the system — common in taller NYC buildings — a fire pump boosts pressure to the required level. County Fire's hydraulic calculations determine whether your building needs one and size it correctly, rather than defaulting to oversized equipment.
Combined sprinkler/standpipe systems are common in NYC high-rises, sharing risers and infrastructure between the two. County Fire designs around standpipe integration requirements from the start rather than treating it as an afterthought — ask about it when you request a quote.
What's Included in Every
Fire Sprinkler Installation
Every County Fire installation starts with hydraulic calculations, not a pipe count. We design around the code requirements your occupancy and building height actually demand.
- ✓Hydraulic CalculationsSystem demand calculated against your building's occupancy classification and available water supply — the foundation every other design decision builds on.
- ✓System DesignPipe sizing, sprinkler head placement, and zoning engineered to your specific floor plan, not a generic layout adapted after the fact.
- ✓DOB Plan FilingPlans prepared and filed with the Department of Buildings under a licensed professional, managed through approval including any amendments.
- ✓Full InstallationComplete installation by licensed technicians — piping, heads, valves, and (where required) fire pump — to the filed and approved design.
- ✓FDNY Acceptance TestingFlow test and main drain test witnessed by FDNY, verifying the system performs to design before signoff.
- ✓As-Built DocumentationAs-built drawings, hydraulic calculations, and all filed permits delivered at project close — everything your next inspector or servicer will need.
- §NFPA 13 Design StandardGoverns sprinkler system design and installation — distinct from NFPA 25, which covers inspection and testing of systems already in service.
- §NYC Fire Code & Building CodeOccupancy-specific coverage requirements layered on top of NFPA 13, governing where sprinklers are required and how they're configured.
- §Water Supply & Fire Pump SizingHydraulic demand calculated against available water pressure, determining whether a fire pump is required and how it must be sized.
- §Standpipe IntegrationCombined sprinkler/standpipe buildings require coordinated design between both systems, not two separate systems designed in isolation.
From Site Assessment

Six steps, one licensed team — no sub-contracted design firm or separate testing company to coordinate between.
What Drives Fire Sprinkler
Installation Cost
Installation pricing varies more than any other fire sprinkler service — a small tenant fit-out and a 40-story new construction project with a fire pump have almost nothing in common cost-wise. Here's what actually moves the number, so your quote makes sense before you get it.
Square footage and occupancy classification determine hydraulic demand, head count, and pipe sizing — the biggest single driver of total cost.
Wet-pipe, dry-pipe, or a combined sprinkler/standpipe system each carry different equipment and labor costs — dry-pipe and fire pump equipment add cost over a standard wet-pipe system.
Piping an open, unfinished space typically costs less than retrofitting an occupied building around tenants and existing infrastructure.
Buildings tall enough that city water pressure can't meet hydraulic demand require a fire pump — a significant cost addition determined by your hydraulic calculations.
Straightforward filings move faster and cost less than projects requiring variances, amendments, or coordination with other filed trades.
Compressed construction schedules or off-hours work in occupied buildings can affect labor cost — we flag this during site assessment.

What Building Owners
& Managers Say
When our fire alarm failed during a critical inspection, County Fire had us back up and running within hours. Their knowledge of exactly what FDNY enforcement looks for is unlike anyone else we have worked with in NYC.
County Fire handled our fire alarm installation, extinguisher program, and semi-annual inspections for a new construction portfolio. Their ARCS compliance expertise helped us navigate FDNY seamlessly — first-time approval on every building.
Five years, multiple commercial properties. Sprinkler installations, semi-annual inspections, fire alarm maintenance — County Fire manages our entire compliance program. Every property passes on schedule. Genuinely reliable.
