Is it reasonable to install fire pipes in the property community in the home of the owner? Still does not meet the fire protection requirements?

This is unreasonable unless it is involved in the contract when you buy a house! If it is not stated in the contract, you should go to a real estate development company. This matter has nothing to do with the property. If you can't contact the developer, you can also go to the property management office to consult the customer service department!
