Almost every element in Pingboard, including Locations, has a Permissions tab for admins to set visibility and accessibility. There are two permissions options available to admins when creating or editing a location:

Employees can view this location – Turning this on or off will change whether or not non-admins can see the location you’re creating
Employees can join and leave this location – Turning this on or off will determine whether or not non-admins will be able to join the location themselves, or whether they will need to be added by an admin.

To edit permissions for an existing location, click on the location you'd like to edit from the Locations section of the Directory, then click on the blue Edit Location button in the top-right corner (or click on the Edit button that appears when you hover over a location's badge).
Permissions options will be at the bottom of the Location editor, and be sure to click Save after you've made your changes.
