We put a 15 kWh battery storage system in our garage and had to build a fire-rated room around it with a 60-minute fire-rated door to maintain code -- which is a pretty heavy weight steel door. It wasn't easy. All to maintain county code. The funny part is by the time we got the inspection, the fire department had a new inspector and he said "wow, you did all of this for the battery?"
