Multi User App- Family Owned Vacation House

We just set up SS in a family owned vacation house- I need to give many family members access to the app in order for many people to monitor cameras and disable alarm remotely before arrival, but don't want them to have access to billing profile, settings, etc. (and they don't want it, either).  How can I give "user level" access to family and retain "administrator level" access for myself, or whomever is going to run the billing and setting side of the system.  

I can't be the only one to be needing this.

Thanks!
