Fire Sprinkler / Fire Alarm System Permit in Lander, Wyoming
Installation, addition, or alteration of a fire alarm, fire sprinkler, or fire suppression system in Lander is not a City of Lander permit product at all — it is processed directly through the Wyoming Department of Fire Prevention and Electrical Safety (State Fire Marshal), which requires a Plan Review and a 'Permit to Construct' for this work 'regardless of size or valuation,' per the Department's own published Plan Review Information page. Resolution 1359 (the City's Fee Schedule 2025-26) has no fire-alarm/sprinkler/suppression line item, and the City's own Application for Building Permit has no checkbox covering this scope, which is consistent with the work being state-administered rather than City-billed.

When you need this permit
- Installation, addition, or alteration of any fire alarm, fire sprinkler, or fire suppression system requires a Wyoming Department of Fire Prevention & Electrical Safety Plan Review and Permit to Construct, regardless of size or valuation, per the Department's Plan Review Information page and W.S. 35-9-108(s)
- Plans for fire alarm systems and fire sprinkler systems must be submitted as successive-phase plans after any initial (e.g., new-construction shell) plans for the same project are approved, per W.S. 35-9-108(s)
- Plans for fire protection systems and for fire detection/alarm systems designed by a NICET III-or-greater professional must be prepared under the direct supervision of a design professional registered to practice engineering in Wyoming; evidence of manufacturer verification is required if the system is manufactured/pre-engineered, per Dept. of Fire Prevention & Electrical Safety Rules, Chapter 2, Section 1(c)(ii)
- No City of Lander Application for Building Permit checkbox exists for a standalone fire alarm/sprinkler/suppression permit — Construction Type, Accessory Structure, Sign, Plumbing, Electrical, Mechanical, and Public R.O.W. are the only categories on the City's own form, confirming this is not a City-fee'd product
- For NEW commercial construction where a fire protection system is part of the building shell, 'details of required fire protection systems' and fire-resistive construction data are instead submitted as part of the standard City of Lander commercial building-permit packet (see this file's residential-commercial-building-permit entry); a standalone State Fire Marshal Plan Review applies to adding or altering a fire protection system independent of, or subsequent to, that base construction project

Final Fire and Life Safety Inspection

Tips
- Plans are accepted or rejected for review within 5 business days of receipt; a complete review is then finished within 21 business days of acceptance, so total elapsed time from submission to a completed review runs roughly 21-26 business days. If the Department requests additional information, review resumes within 10 business days of receiving it, or the original 21-day window, whichever is longer, per the WSFM's published Plan Review process and W.S. 35-9-108(b)-(c).
- Lander's own local IFC amendment (LMC 3.14.20, amending IFC Section 1103.5.3) sets January 1, 2027 as the compliance deadline by which certain existing buildings must have automatic sprinkler systems installed — a sprinkler system installed to meet that City retrofit deadline still goes through this same State Fire Marshal Plan Review / Permit to Construct process, since the City has no separate fire-sprinkler permit product of its own.
- No work may begin before the Permit to Construct is issued, and fees are due before plans are logged as accepted; pay by credit card in the applicant's portal account or by check mailed to the Department's Cheyenne office (320 W. 25th St., 3rd Floor, Cheyenne, WY 82002).
