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

Section 162-14E(2) requires a minimum of one single-station smoke detector in the vicinity of each sleeping area in every housing unit covered by the chapter, installed and maintained per Public Safety Article, Title 9, Subtitle 1 of the Annotated Code of Maryland, as amended by Bill No. 24-024. Section 162-3A limits the Minimum Livability Code, and this smoke-alarm duty, to rental structures used for human habitation; owner-occupied single-family homes, housing the Department has exempted, rent-free arrangements, and employer-provided housing fall outside it. Section 162-15F puts the ongoing duty to install and maintain the smoke detector on whoever the state law assigns it to, tracking the same Title 9, Subtitle 1 standard.

When a Code Official finds a missing or nonworking alarm, Section 162-8B requires a notice of violation stating the corrective measures and deadline before any citation issues, though Section 162-8C lets the Official skip straight to a citation at his discretion. Any judgment tied to a citation becomes a lien on the property, collectible like real property taxes under Section 123-32.
