Appleton, WI Fire Regulations: Smoke Detectors (2026)

Sec. 6-60(b)(1) requires each dwelling unit to have a minimum of one approved smoke alarm installed in a manner and location consistent with its listing, and it directs owners with installation questions to the Fire Department's Fire Prevention Division. Sec. 6-60(b)(2) folds in the state standard for existing dwelling units, requiring compliance with the Wisconsin Uniform Dwelling Code, Wis. Admin. 01, meaning each unit needs at least one approved, listed and labeled alarm that senses visible or invisible combustion particles, installed consistent with its listing.

Sec. 6-60(c) requires any smoke alarm or heat detector used to satisfy the section to be approved by Underwriter's Laboratories, Factory Mutual, or a comparable testing firm, not an unlisted device. Sec. 6-60(d) has the Division of Inspections carry out inspection of new construction at final inspection, tying the alarm requirement into the building permit process rather than leaving it to a separate fire inspection. Sec. 6-60(e) is a real-estate transfer safeguard: no person may convey real property containing a dwelling unit unless approved smoke alarms are installed as required by subsection (d), and a purchaser who finds noncompliance may sue in circuit court for damages, though a violation does not affect the validity of the conveyance of title or possession itself.

The section defines a 'dwelling' broadly as a structure providing complete, independent living facilities including sleeping, eating, cooking and sanitation, and separately defines sleeping areas to clarify how many alarms a unit with divided bedrooms may need.
