Can I charge the property management fee if the rental house is not qualified?

You can refuse to pay the property management fee in the following circumstances: First, the property company is not qualified; 2. No property contract has been signed.

And the situation you mentioned is really a bit special: the owner of the house you rented has set up a department to maintain and manage the property, which can be regarded as autonomy to some extent. Autonomy is permitted by law, and you have no qualification management certificate.

If you don't recognize the property management fee, there is another way: you can check whether there is an agreement in the lease contract you signed at the beginning, and you have to pay if there is one. Even if you don't, and you accept their services, the actual contract still exists, and you should still pay the fees.
