With a bit of CSS hacking, yes.

Not if you configure it like this

> I’m talking about approving or removing access to the forum **per user**. So no, your landlord can’t change your words, but **they** ’re the ones with authority to confirm your signup as a resident, and if you become a troll they can mute or ban you

Who’s “they” in that sentence? The landlords?  
Are those the ones that are going to decide whether their residents are trolling? 🍿

To me it just sounds like you’ll have _owners_ and _residents_.

- Put the _owners_ in a group.
- Give everyone a custom field that identifies the property.
- When someones signs up, look up the owner of the property by finding the person in the _owners_ group with the same property, and ask them to confirm. Once they have confirmed, put the resident in the _residents_ group.
- Make sure to have a good procedure to cater for when someone leaves.
- Forget about the moderation by owners (if I understood you correctly) and leave that to staff.
