Full Breakdown
14(C)(1)(c) of the Land Development Code, part of the county's short-term vacation rental standards adopted February 19, 2015, requires that if an interconnected and hard-wired smoke and carbon monoxide detection and notification system is not already in place in a short-term vacation rental unit, the owner must install and maintain an interconnected, hard-wired carbon monoxide alarm system meeting Florida Building Code Section R315, Carbon Monoxide Alarms. This CO alarm duty is one line in a broader life-safety package that a rental must pass before it is certificated: a portable 2A:10B:C dry chemical fire extinguisher on every floor, inspected and maintained under NFPA 10; battery-powered emergency lighting illuminating the primary exit for at least one hour (units certificated before this standard was codified had until December 31, 2016 to add it); and compliance with the Residential Swimming Pool Safety Act, Chapter 515, Florida Statutes, for any pool, spa or hot tub on site. S. Highway 1, single-family and two-family dwellings only; it is not a general county-wide CO detector mandate for owner-occupied or long-term rental housing.
Violations & Fines
An initial Short-Term Vacation Rental Certificate cannot be issued under Section 3.06.14(F)(1) until an inspection confirms the CO alarm system is in place and any deficiencies are corrected and re-inspected; on annual renewal or transfer inspections, a missing or non-functioning system is a violation subject to Section 3.06.14(K)'s progressive enforcement, a warning with a correction period first, then a civil citation with board-set fines for continued noncompliance.
