My home is in a residential area, and the door lock is covered with glue. Is the property responsible?

This kind of thing should be viewed from two aspects:

First, have you offended anyone or been in arrears with the final payment of the decoration? Generally, only in this case will someone continue to destroy your living environment;

Second, the responsibility of the property is not to keep detailed records of visitors. Of course, if the decoration company or the person in charge has other decoration projects in your community under the circumstance that the above decoration balance is overdue, then the property can't help but let it enter;

So you have to confirm your actual situation from two aspects. Of course, there may be some questions about your character, but generally speaking, property companies pay attention to the registration and confirmation of visitors, so make sure you have any questions here before consulting with the property company.
