Is the key to the new house owned by the developer or the property management company?

The key to a new house is usually handed over to the property by the developer after the house is completed, and then handed over to the owner by the property. The property company has no right and obligation to keep the key;

If the owner finds problems in the process of house inspection and needs rectification, the property company will generally contact the construction unit and the owner to make an appointment for on-site maintenance;

If the owner finds it inconvenient, he can entrust the key to the maintenance personnel of the property or developer according to the owner's wishes. This is not clearly defined, and it is entirely determined by the owner's wishes.

Generally speaking, unless required by the owner, the property management company is unwilling to take over the owner's keys, because they have management responsibilities during the key storage period. In other words, if the glass is broken or something is lost during this period, they need to pay compensation.
