What is the purpose of collecting fire protection fees in the community? Where are all the fire fighting expenses paid by the owners of the community used?

According to the relevant provisions of the Fire Protection Law, the fire department is fully obligated to carry out fire fighting and prevention, and will not charge the owner any fees at all. The so-called "community fire protection fee" you mentioned should be formulated, collected and managed by the community property.

Literally, the "fire fighting fee" you mentioned should be the cost of purchasing and maintaining fire fighting facilities such as fire extinguishers in residential properties. The maintenance of stair lights, regardless of whether there is a "fire fee", should be maintained by the property, so it should be paid by the property service fee.

Because it's the first time I've heard of the so-called "fire fee", I can only answer the first question for sure. The second answer is just a personal opinion, for reference only.
