What are the standards for the secondary water supply fee, elevator fee and property management fee for people who have bought small high-rise buildings and have not lived yet?

Property management fees are charged according to the property service contract. The house sales contract should be attached to it.

The water fee for secondary water supply is generally divided into water fee and water supply electricity fee. Or collect them together. Take it if it's useful, and confiscate it if it's useless. Generally, the seasonal or stepped charges of water supply companies plus the average electricity charges generated by water supply are used for pricing.

I don't know what you mean by the elevator fee. If it is the electricity fee for elevator operation, it shall be shared by the elevator owner by area or by household. If it is the annual maintenance premium of the elevator, this clause cannot be included in the previous contract. If it is after the owners' committee, it can be agreed in the contract.
