Oak Park, IL Building Safety: Carbon Monoxide Detectors (2026)

Section 8-32-4 of the Oak Park Village Code sets the standards a property must meet before the Village licenses it as a bed and breakfast, a use permitted in one- and two-family dwellings under Article 32 of the Village's business licensing chapter. Subsection H requires the establishment to meet the state fire marshal's rules for one- and two-family dwellings, then layers on Village specific requirements, including subsection H(11): carbon monoxide detectors installed on every building level, from the basement up through any habitable attic space the owner uses.

That mandate sits alongside a companion rule in the same subsection requiring an integrated, supervised fire alarm system with smoke detectors carrying light and horn strobes in every guest sleeping room, in hallways near those rooms, and on every level including the basement. Before the Fire Department signs off, the owner must submit a floor plan showing the building's size, exits, emergency lighting, fire alarms, and the location of the smoke and carbon monoxide detectors, under subsection H(15). This carbon monoxide requirement is scoped to licensed bed and breakfast establishments operating under Article 32; it is not framed in this Village Code as a mandate for every dwelling in Oak Park, and the annual licensing process is what triggers Fire Department review of detector placement.

A bed and breakfast that fails inspection cannot obtain or renew its license, because Section 8-32-3 blocks issuance or renewal until the Village has inspected and approved the building against these standards.
