What if the neighbor agrees to change the outer door and the property disagrees?

If the neighbors agree to open the door outside, but the property does not agree, you can try the following steps:

1. Understand the property regulations: first, check the property management regulations to find out whether it is allowed to open the door outside. If the property permits, then you can ignore the opinions of the property and directly construct.

2. Negotiation with the property: If the property is not allowed to open to the outside world, you can negotiate with the property, explain the reasons and benefits of opening to the outside world, and promise not to affect other owners during the construction period. If the property agrees, the construction can proceed smoothly.

3. Seek legal aid: If negotiation with the property fails, you can seek legal aid. According to the relevant laws and regulations, the owner has the right to possess, use, benefit and dispose of the exclusive part of the building. However, the owner's exercise of rights shall not endanger the safety of the building or damage the legitimate rights and interests of other owners. If the property still disagrees, you can consider complaining or suing the relevant departments.

I hope the above information is helpful to you.
