Does the community security have the right to prevent non-residents brought by the owner from entering the community?

First of all, look at the ownership and use right of roads in the community. Generally speaking, it belongs to all owners. According to the general principle of real right, only the owners of the community have the right to use, benefit and dispose of the roads in the community. Therefore, whether the service road in the community is open to the outside world is decided by the community owner.

The relationship between the owner and the property is only the housekeeper invited by the owner of the community, and the access to the community can only be managed according to the owner's decision (generally subject to the decision of the owners' Committee). Without the owner's decision, the property generally cannot decide the management authority of the entrance and exit of the community without authorization.

Understand the ownership and use right of residential roads from the above two points. That is, whether the roads in the community are smooth or not is in the hands of the owners. But there are exceptions, that is, the problem of adjacency. If residential entrances and exits are historically formed, the entrances and exits for long-term use by surrounding residents should generally remain intact. Secondly, if the channel in the community is the only channel for the surrounding residents or it is too inconvenient to use other channels, you can ask the community to open the community channel. Thirdly, if community access involves public interests, we can ask the government to ask the community to open community access for public use.
