'Granularity' of access by contractor or employee?

'Granularity' of access by contractor or employee?

I have a forthcoming project where I will be working with a contractor in my office.

 

I think that I would like to provide the contractor access to Projects, but only some parts of the projects that I have set up.

 

Q: I have read on how to add a user to Projects, but I would like to know at what ‘level’ can I restrict access to the

    contractor: limits can be set on task? task list? In other words, how ‘refined’ or ‘granular’ can I restrict access?




 

Thanks.
