Fire Protection subcontractors

Fire Protection subcontractor COI requirements

Fire protection contractors lay out, install and test the sprinkler and suppression systems a building relies on. Their work is tested only when something goes wrong, either a fire the system fails to control or a release that floods finished space. Pikorua Security's 2026 benchmark puts fire protection at 64% deficient on first review, with design responsibility and water damage wording behind most findings.

Endorsement checklist

Forms to see attached, not just checked

A Y in the ADDL INSD column is not an endorsement. Ask for each form below by number and edition, and read the fire protection sub's schedule of forms against it.

Exclusion watchlist

Exclusions that void fire protection coverage

These never appear on an ACORD 25. They sit in the declarations schedule of forms and the endorsement pages, which is where Pikorua Security reads.
  • Red flag

    CG 22 79 Exclusion, Contractors, Professional Liability

    Sprinkler layout and hydraulic calculations are design work. If a system fails to control a fire because the design was inadequate for the hazard, CG 22 79 can push the claim off the CGL. Require a professional policy or a CGL that does not exclude the sub's own design.

    Read the CG 22 79 guide
  • Red flag

    Fire suppression system or failure to protect exclusion

    Some carriers exclude damage arising from the failure of a fire protection system to perform. For a sprinkler contractor, that removes the core exposure the GC and owner are transferring.

  • Red flag

    PFAS exclusions

    ISO and carriers have introduced exclusions for perfluoroalkyl and polyfluoroalkyl substances. Contractors that install or service foam suppression systems using AFFF should be asked how PFAS claims are covered.

  • Red flag

    Water damage or sprinkler leakage limitations

    Manuscript wording that limits property damage from water discharge. Leaks during hydrostatic testing and accidental discharge after occupancy are the most frequent fire protection claims.

Sprinkler contractors are designers too

On most commercial projects, the fire protection contractor prepares the sprinkler layout and hydraulic calculations to NFPA 13 from the engineer's performance narrative. Layouts are usually prepared by NICET-certified technicians and submitted to the authority having jurisdiction. In insurance terms, that is a professional service, and contractor CGL policies routinely exclude professional services through CG 22 79 or a similar carrier form.

If a warehouse fire overwhelms a system because the hydraulic design did not account for the storage commodity, the claim is a design claim. Require contractors professional liability on fire protection subcontracts that include layout or calculations, and verify the retroactive date precedes the start of layout on your project.

Testing, discharge and finished floors

Fire protection water losses cluster around two moments: hydrostatic testing before ceilings close, and accidental discharge after occupancy from a damaged head or a freeze in an unheated area. Both can damage finished work owned by the GC, the owner or tenants. The sub's CGL should cover this property damage without a water damage limitation, and the GC should be an additional insured for both ongoing and completed operations.

  • Ask whether the CGL limits property damage from water discharge.
  • Confirm CG 20 37 is attached at the same edition as CG 20 10.
  • Check that the umbrella follows form over completed operations.

Inspection, testing and maintenance after turnover

Many fire protection contractors stay on after turnover to perform inspection, testing and maintenance under NFPA 25. For property managers and REITs, that is a vendor relationship with ongoing operations exposure for years. Pikorua Security moves the vendor from the GC's project template to the property's service vendor template, so CG 20 10 ongoing operations status is required again for the maintenance contract.

How to verify a fire protection sub's COI

A manual review of one COI and its endorsement packet takes 25 to 40 min (CFMA Time Study). These are the six checks, in the order Pikorua Security runs them.

  1. 1

    Match the named insured to the subcontract

    Compare the named insured on the ACORD 25 with the legal entity that signed the fire protection subcontract, including the LLC or Inc. suffix. A trade name or DBA is not the contracting entity, and additional insured coverage follows the policy's named insured.

  2. 2

    Check limits against your fire protection exhibit

    Confirm commercial general liability of $1,000,000 each occurrence / $2,000,000 general aggregate, an umbrella of $5,000,000 that follows form over CGL, auto and employer's liability, and statutory workers compensation. Then confirm contractors professional liability is evidenced, because it does not appear on a standard ACORD 25.

  3. 3

    Read the endorsement pages, not the checkboxes

    A Y in the ADDL INSD or SUBR WVD column is not an endorsement. Confirm CG 20 10, CG 20 37, CG 20 01, CG 24 04, WC 00 03 13, CA 20 48 and CG 25 03 are attached as forms, and that the ongoing and completed operations forms share the same edition date.

  4. 4

    Scan the schedule of forms for fire protection exclusions

    Look for CG 22 79 Exclusion, Contractors, Professional Liability, fire suppression system or failure to protect exclusion, PFAS exclusions and water damage or sprinkler leakage limitations. None of these appear on the certificate; they sit in the declarations schedule of forms and the endorsement pages.

  5. 5

    Check carrier ratings and policy dates

    Confirm each carrier is rated A- VII or better by AM Best and that no policy expires before the fire protection scope and its completed operations period are finished. Set renewal reminders at 60, 30, 15 and 0 days.

  6. 6

    Hold payment and site access until resolved

    Keep the fire protection sub's pay applications and jobsite badges on hold until every finding is resolved, then file the verified packet so it is ready if you ever need to tender a claim.

Questions

Fire Protection COI questions

Do fire sprinkler contractors need professional liability insurance?
When they prepare sprinkler layouts and hydraulic calculations, yes. That is design work, and CGL policies commonly exclude professional services through CG 22 79. A contractors professional liability policy responds if a system fails because of an inadequate design.
What defect rate do fire protection COIs have?
Pikorua Security's 2026 benchmark puts fire protection subcontractors at 64% deficient on first review, below the 71% average across all subcontractors. The most frequent findings are professional services exclusions on design scopes and water damage limitations.
What should a property manager require from a sprinkler inspection vendor?
Ongoing operations additional insured status (CG 20 10 or a blanket equivalent), CG 20 01 primary and noncontributory wording, waivers of subrogation on GL and WC, and limits matching the service agreement. Inspection and maintenance under NFPA 25 is ongoing work, so ongoing operations status matters for the life of the contract.
