110v Smoke Detectors

We are in a ranch house and we are remodeling the kitchen, dining room and family room. This is one big space in the back of the house with no walls separating the space. In the old dining room there was just one battery operated spoke detector. There are other battery operated smoke detectors for the bedrooms and in the hallway.

What are the requirements for smoke detectors in the new space? We are adding a gas cooktop and a gas fireplace in the family room. Are we required to have CO or Smoke detectors in the family room and kitchen or what?

Here is the code from Ohio for smoke detectors. Doesn't say anything about kitchens spaces.

I don't believe code calls for smoke detectors in kitchens, they go off too often that way. I would check with your local building inspector, they are the one you need to satisfy in the end anyway.

By the way, nominal voltage in the US is 120 volts and you need CO detectors, not CO2.

Typically the building code requires a smoke alarm on each floor, in each bedroom and outside any sleeping areas.

As Mitch mentioned, don't put a smoke detector in the kitchen. You'll curse it everytime you boil water or burn something.

I know locally, all new construction requires a AC powered detector (120V) and I believe a CO detector per floor.
I'm currently in the process of slowly replacing my smoke detectors with AC powered units. The previous owner had 9 battery detectors in the house. Gets expensive twice a year and definately a PITA to replace all those batteries when I can barely reach them (10-12' ceilings).

pcboss nailed it.

Also, depending on what codes are in effect in your area, your renovation probably triggers retrofit of ac/dc smokes in areas of the existing home as if new.
