What's different about smoke & co detector installation in Missoula
Rentals near the University of Montana must keep working alarms in every unit. Renovations under permit typically require hardwired, interconnected alarms. Test alarms monthly. Permits come from the City of Missoula's development services. Wood stoves and pellet stoves make CO alarms especially important in winter.
Older homes near the university and downtown can still have knob-and-tube or ungrounded wiring, and small services are common. Electric heat, heat pumps, garage and shop circuits and EV chargers often push panels past their capacity.

Summers are short and dry, and wildfire smoke from fires across the region often settles into the valley, keeping windows closed and air purifiers and AC running.
