Is it reasonable for the property to charge for secondary heating of high-rise buildings? Is the charge for secondary water supply for five floors reasonable?

Whether it is reasonable for the property to charge the secondary heating fee for high-rise buildings needs to be judged according to the specific situation. Generally speaking, it is reasonable for the property to charge the secondary heating fee for high-rise buildings, because the secondary heating is charged according to the project, which is a reasonable behavior.

For the five-story secondary water supply cost, it also needs to be judged in combination with the specific situation. Generally speaking, the property should not charge the secondary water supply fee, because the law stipulates that the water supply unit should charge the relevant fees to the end users. However, if the realty service enterprise accepts the entrustment to collect the above fees, it shall not collect any additional fees such as handling fees from the owners.

Therefore, the specific situation needs to be judged according to local policies and regulations and specific contract stipulations. I suggest you consult relevant policies, regulations and contract terms, or consult professionals to help you judge.
