Can I ignore the property if the balcony is not unified?

If the property requires a unified balcony, but you don't want to seal the balcony, you can raise an objection to the property management department, but you still need to comply with the property requirements in the end. If the property requirements violate the law, you can complain to the relevant departments, which will handle them.

From the legal position, the relationship between the property company and the owner is a kind of entrustment relationship, and the property company has no right to manage and restrain the owner in the process of property service. However, if the owner's balcony sealing behavior infringes the interests of other owners, or violates the provisions of property management regulations, the property company has the right to obstruct or interfere.

Therefore, if your balcony closure behavior does not infringe the interests of other owners, nor does it violate the provisions of the property management regulations, you can ignore the requirements of the property. But if your behavior violates relevant regulations, you may have to bear corresponding legal responsibilities. I suggest you consult relevant legal professionals before making a decision.
