How to make a custom division of rights in the django admin?

Question

Django

django 1.11
There is a "city" model and an associated "person". That is, a person has a "city" field through ForeignKey.
In the admin panel, you need to create a user who has access to people, for example from Omsk? I would like to implement this at the level of the standard admin panel, and not rewriting everything from scratch.
