Additional Clauses for BP Lease Templates?

[Brad Collins]

We are using the landlord forms provided by Bigger Pockets as the starting point for our leases/application/pet addendum/etc. These are a fantastic resource and we're very grateful that they were included with the Pro membership!

My question is: What unique requirements have you added to your lease and why? 

Presumably, some of these have come about based on prior negative experiences with tenants. For example, I was listening to a past episode of the BP Podcast and the guest mentioned that they have a clause prohibiting political banners & signs after two tenants had a dispute over a large flag hanging from the porch.
