Tenant Improvement Fire Protection
Modifying or building out a new tenant space? We handle all fire sprinkler modifications, additions, and code compliance work so your TI project stays on schedule and passes inspection.
When a new tenant moves in, the fire sprinkler system almost always needs to be modified
New walls mean new coverage zones. New ceiling layouts mean relocated heads. A change in occupancy type can mean an entirely different hazard classification and sprinkler density requirement.
Hydrotek Fire Systems specializes in the fire protection side of tenant improvement projects. We work with general contractors, property owners, architects, and building departments to design, permit, install, and inspect fire sprinkler modifications that keep your TI project moving and code-compliant from day one.
What Triggers Fire Sprinkler Work in a TI?
Almost any change to a tenant space will impact the existing fire sprinkler system
New Walls & Partitions
Adding or relocating walls changes room sizes and creates new enclosed spaces that each need their own sprinkler coverage. Heads must be repositioned to eliminate blind spots.
Dropped or Modified Ceilings
New drop ceiling grids, exposed ceiling designs, or changes in ceiling height all affect sprinkler head placement, deflector distances, and coverage patterns.
Change of Occupancy
Converting a space from one use to another — retail to restaurant, office to medical, warehouse to gym — often changes the hazard classification, requiring different sprinkler types, spacing, and water density.
Kitchen or Cooking Equipment
If the new tenant is adding commercial cooking equipment, a kitchen hood fire suppression system will be required in addition to any sprinkler modifications.
Storage & Shelving Changes
High-piled storage, rack configurations, and shelving layouts can affect sprinkler requirements. NFPA 13 has specific rules for in-rack sprinklers and high-piled storage protection.
Demising or Combining Suites
Splitting one large suite into multiple smaller ones — or combining several suites into one — requires re-evaluating the entire sprinkler layout and potentially adding new branch lines and risers.

Plan Review & Design
We review your TI architectural plans and identify every fire sprinkler impact — relocated heads, added heads, pipe rerouting, hazard reclassification, and any code upgrades triggered by the build-out. We produce shop drawings, submit for permit, and coordinate with the AHJ so the fire protection scope is locked in before your GC starts framing.
Sprinkler Relocation & Addition
We relocate existing sprinkler heads to align with new wall and ceiling layouts, add new heads for additional rooms and coverage zones, extend or reroute branch lines, and install new drops — all while keeping the existing system operational for the rest of the building. Our work is scheduled around your GC's construction timeline to avoid delays.
Occupancy Change Upgrades
When the occupancy type changes, the fire protection requirements often change with it. A space classified as Light Hazard for an office may become Ordinary Hazard Group 1 for a retail store or Ordinary Hazard Group 2 for a restaurant. We assess the new classification, verify that the existing system can support the increased demand, and make whatever upgrades are needed — from head swaps to full system redesigns.
Kitchen Hood System Installation
If the tenant build-out includes commercial cooking, we install the required kitchen hood fire suppression system alongside the sprinkler modifications. We coordinate nozzle placement with the hood installer, connect the gas shut-off, install the manual pull station, and ensure everything passes the fire marshal's inspection together — not as separate callbacks.
Final Inspection & Sign-Off
We schedule and attend the final fire sprinkler inspection with the AHJ, provide all required documentation — as-built drawings, test reports, material certifications — and make sure everything passes so you can get your certificate of occupancy without fire protection holds. If corrections are needed, we handle them immediately.
Our TI Process
Simple, transparent, and coordinated with your construction timeline
Review Plans
You send us the TI architectural drawings. We review them, identify the fire sprinkler scope, and provide a detailed estimate — usually within a few business days.
Design & Permit
We produce shop drawings, run hydraulic calculations if needed, and submit for permit with the local building department and fire marshal.
Coordinate with GC
We schedule our rough-in work around framing, mechanical, and electrical to avoid conflicts and keep the construction timeline on track.
Install
Our crew installs, relocates, and tests all sprinkler modifications. We work clean, communicate with the GC daily, and stay out of other trades' way.
Inspect & Close Out
We schedule the fire marshal inspection, attend it, handle any corrections on the spot, and deliver final documentation so you can close out the permit.
