Rochester, Minn., Code of Ordinances § 7 § 7-8-44
Interconnection (Rochester Housing Code)
Operative Text
Where more than one smoke alarm is required to be installed within an individual dwelling or sleeping unit, the smoke alarms shall be interconnected in such a manner that the activation of one alarm will activate all of the alarms in the individual unit. Physical interconnection of smoke alarms shall not be required where listed wireless alarms are installed and all alarms sound upon activation of one alarm. The alarm shall be clearly audible in all bedrooms over background noise levels with all intervening doors closed. Exceptions: (1) Interconnection is not required in buildings that are not undergoing alterations, repairs or construction of any kind. (2) Smoke alarms in existing areas are not required to be interconnected where alterations or repairs do not result in the removal of interior wall or ceiling finishes exposing the structure, unless there is an attic, crawl space or basement available that could provide access for interconnection without the removal of interior finishes.
Rochester, Minn., Code of Ordinances § 7 § 7-8-44 requires that when multiple smoke alarms are installed in a single dwelling or sleeping unit, they must be linked so that triggering one sets off all of them. Wireless alarms that achieve the same effect are an acceptable alternative to physical wiring. Two exceptions apply: interconnection is not required in buildings not undergoing any construction or alteration, and existing areas undergoing limited repairs are exempt unless accessible spaces like attics or basements make interconnection feasible without opening walls or ceilings.
Plain English — not legal advice.
Operators managing properties in Rochester should ensure that any dwelling or sleeping unit with multiple smoke alarms meets the interconnection standard set out in Rochester, Minn., Code of Ordinances § 7 § 7-8-44, whether through hardwired connections or listed wireless systems. Compliant operators typically verify that all alarms sound simultaneously and remain audible in every bedroom with doors closed. When undertaking alterations or repairs, operators generally assess whether accessible spaces such as attics, crawl spaces, or basements allow interconnection without removing interior finishes, since the exceptions in § 7-8-44 are tied specifically to the scope and nature of the work being performed.

Under Rochester, Minn., Code of Ordinances § 7 § 7-8-44, tenants in units with multiple smoke alarms have an interest in confirming that those alarms are properly interconnected and audible throughout the unit, including in bedrooms with doors closed. If a tenant believes the smoke alarms in their unit do not meet this standard, they may raise the issue with their landlord in writing, contact Rochester's local code enforcement or housing inspection office to request an inspection, or reach out to a tenant-rights organization for general guidance. Awareness of the exceptions in § 7-8-44 — particularly those tied to ongoing construction or alterations — can help tenants understand when interconnection requirements are and are not triggered.
