Is it legal for the property to refuse to use gas tanks?

Whether this situation is legal or not depends on the specific situation.

Some high-rise apartments or residential quarters may have potential safety hazards, so it is forbidden to use gas tanks to ensure the safety of owners. In this case, the property regulations may be legal. If the property prohibits the owner from using gas tanks without reasonable basis, then this behavior may be illegal.

Even if the property has relevant regulations, laws, regulations and relevant policies should be followed when formulating and implementing the regulations, and the legitimate rights and interests of the owners should be respected.
