Cecil County, MD Fire Regulations: Smoke Detectors (2026)

Section 240-9D(2) requires smoke alarms or detectors to be installed outside each separate sleeping area, in the immediate vicinity of the bedrooms, in every residential structure covered by the Minimum Livability Code. The detectors must be installed and maintained in accordance with the state fire laws and the building and electrical codes Cecil County has adopted, and when actuated must provide an alarm suitable to warn occupants within the unit (§ 240-9D(3)-(4)). Section 240-16L assigns the installation and functioning duty to the property owner: the owner must install and maintain in good working order a smoke detector consistent with the state fire laws found at Public Safety Article, Title 9, Subtitle 1, Annotated Code of Maryland, Smoke Detection Systems, and any county code meeting or exceeding those standards.

Once a tenant occupies the unit, responsibility for maintaining the smoke detector shifts to the tenant for the duration of that occupancy. Chapter 240 also requires fire protection systems generally to be kept in proper condition (§ 240-9D(1)), fire-resistance-rated doors and smoke barriers to remain in working order with functioning hardware (§ 240-9D(6)), and bans door stops, wedges or hold-open devices that lack required approvals (§ 240-9D(7)). These firesafety requirements sit alongside the code's egress rules, which require every sleeping room to have an operable window or exterior door for emergency escape, or access to two separate exits (§ 240-9A(6)).
