Yep, one in the utility room by the furnace, one in the upstairs front door closet beside the kitchen, and one in the garage. Haven’t had to use them for myself personally… but the neighbours came slamming on the door a few times needing one.
IMO every residence should have one handy. Never know what could happen or who might need one. I really should get one thats rated for electrical fires however.
