Tips
- Florence Fire/Medical Department (520-868-7609) handles fire sprinkler plan review and inspections directly — call them, not just Community Development, for submittal/fee/inspection questions specific to fire systems.
- Underground fire line work needs its own separate permit — don't assume it's bundled into the Fire Sprinkler Permit.
- The Fire Department's own 2025 application lists tiered fees ($175-$300 depending on scope) that don't match the Town-wide Fee Schedule's single flat $300 line — budget using the Fire Department's own current application as the more specific figure, but confirm with Fire Prevention staff before paying.
- Fire sprinkler permits fall under the 'Fire Review' category on the Town's Submittal Review Timelines chart: 20 business days for 1st/2nd review, 15 for subsequent, plus the 10-business-day Administrative Review that applies to all formal-review categories.
