Summary
Lee County does not require fire sprinklers in one- and two-family homes or manufactured homes; Section 6-553 exempts them from the supervisory-facility standard applied to other sprinkler systems. Multifamily, commercial and industrial buildings outside an established fire district must instead install an automatic suppression system under Section 6-555(b)(2).
Every required fire sprinkler system or other form of fire identification or suppression system installed in conjunction with, or as an alternative to, a required fire sprinkler system, must have supervisory facilities as set forth in NFPA 72, as adopted pursuant to Section 6-554. An exemption from this special application exists for sprinkler systems installed in one- and two-family homes or in manufactured homes.

Full Breakdown
Lee County's Uniform Fire Code, Chapter 6, Article VI of the Land Development Code, treats single-family homes differently from larger buildings when it comes to fire suppression. Section 6-553 requires every fire sprinkler system, or an alternative suppression or detection system installed in its place, to carry supervisory facilities meeting NFPA 72 as adopted under Section 6-554, but the same section specifically exempts sprinkler systems installed in one- and two-family homes and in manufactured homes from that supervisory-facility requirement. Section 6-555 fills the gap for construction outside an established fire district, meaning outside the boundaries of a fire district created by special act of the legislature; the County Fire Control District created by a 1945 special law is expressly excluded from that definition.
There, single-family homes, duplexes and manufactured homes must instead carry a complete automatic fire detection system covering all areas, wired to a control panel with battery backup, with detectors placed according to the latest NFPA alarm standard, rather than a fire sprinkler system. Multifamily, commercial and industrial buildings in those same areas have no detection-only option: Section 6-555(b)(2) requires either a complete automatic fire suppression system built to NFPA 13 or NFPA 13R, or, in lieu of a suppression system, establishment of an NFPA 1201 volunteer fire company approved by the County Fire Official plus an NFPA 1231 water distribution system. Decisions of the Fire Official under this article can be appealed to the County Board of Adjustment and Appeals under Section 6-557.
Violations & Fines
A violation of the Uniform Fire Code, including installing a required suppression system without the NFPA 72 supervisory facilities Section 6-553 demands, or skipping the detection or suppression system Section 6-555 requires outside a fire district, is a civil infraction under Section 6-558 carrying a penalty up to $500.00, with each day of continued violation counted as a separate offense and the county entitled to seek injunctive relief.
