Fire Sprinkler & Fire Alarm System Permit in Gilbert, Arizona

Gilbert has its own municipal fire department (Gilbert Fire & Rescue), and its Fire Prevention Division reviews fire sprinkler, standpipe, and fire alarm/monitoring system plans — but not as a separate department application or fee system. Per the Town's own 'Fire Plan Review' page, Development Services (not a standalone Fire Department permit desk) reviews and approves Fire Alarm Systems, Automatic Fire Extinguishing Systems, and Standpipes as a Deferred Submittal tied to the project's Master Building/Construction Permit, submitted through OneStopShop and accompanied by the Town's Fire Protection Checklist. Despite being processed through the same Building Permit workflow, fire protection systems are billed under a genuinely distinct, flat (non-valuation-based) 'Fire Permit & Plan Review Fees' table in the Town's fee schedule, and have their own published review-timeline goals separate from standard commercial plan review.

Tips

  • Fire sprinkler and fire alarm plans are NOT submitted to a separate Gilbert Fire & Rescue permit desk — they go through the same OneStopShop Construction Permit Application as a Deferred Submittal, referencing the Master Building Permit number, with Development Services routing plan review to the Fire Prevention Division.
  • Despite sharing the Building Permit application workflow, fire protection systems are billed on a distinct FLAT Fire Permit & Plan Review Fees table (by system type and size tier) rather than the valuation-based Building Permit Fee table used for general construction.
  • All Fire Protection System sheets require an Arizona-registered PE seal under BTR Substantive Policy #3, with narrow exceptions: shop/installation drawings may be done by a minimum NICET III, and sprinkler modifications of 20 heads or less (non-High-Hazard, non-monitoring-only) may be done by a NICET II.
  • Review timelines vary significantly by scope: new Fire Plan Submittals run a 12/8-working-day goal (30-day statutory substantive-review max), Fire Sprinkler Modifications under 20 heads (and alarms) run a faster 8/4-working-day goal (25-day statutory max), and modifications under 5 heads run a minimal 3/3-working-day goal with no statutory max listed.
  • The Town of Gilbert is currently enforcing 2016 NFPA 13/13R/13D, 2017 NFPA 58, 2016 NFPA 72, and 2018 I-Codes/2017 NEC for fire protection systems, per the Fire Protection Checklist.

No. Gilbert Fire & Rescue's Fire Prevention Division reviews fire alarm, sprinkler, and standpipe plans, but submittal happens through Development Services' OneStopShop Construction Permit Application as a Deferred Submittal tied to the Master Building Permit — not a standalone Fire Department application. However, the Town's Development Services Fee Schedule does contain a dedicated, flat 'Fire Permit & Plan Review Fees' table (distinct from the valuation-based Building Permit fee) specifically for these systems.
