The revised housing code in our area requires each home to have a 10lb ABC rated fire extinguisher, regardless of how many smaller units you have.

After hearing about the change, I decided it was a good time to update myself to code. So I bought a 10lb unit which I mounted out in the garage. I also took the opportunity to replace the 2.5lb units that were in the kitchen, furnace room, and laundry room since they were going on 15 years old.

The only two I haven't gotten around to replacing are the ones in our cars. They're fairly new though, so I'm not really worried about 'em.
