Cost to Smoke & CO Detector Installation in Kansas City, MO (2026)

If you’re budgeting a smoke & co detector installation in Kansas City, most projects run $614-$2,865, 2% above the $1,400 national average. What moves that number most is usually one thing: Battery-only vs. hardwired interconnected. On its own it can swing the cost by $500 - $2,000 difference in total install, so that’s the decision to slow down on before you sweat the smaller stuff.

Easiest place to save: Replace all detectors at once rather than one at a time. If any detector is more than 10 years old (check the date on the back), replace the whole system. Detector sensitivity degrades with age. Doing all at once also means one electrician visit and one set of hardware.

In the Midwest (where Kansas City sits): Competitive electrical market and lower wages reduce total install cost.
