NFPA 72 is the national alarm code that South Carolina adopts. Briefly: a smoke alarm in every bedroom, one in every hallway outside sleeping areas, and one on every level including the basement. CO alarms within 10 feet of every sleeping area. We audit your home for free and tell you what's missing.
Within 10 feet of every sleeping area, in any home with a gas appliance, gas water heater, fireplace, or attached garage. Most homes need at least 2 CO detectors.
