BP Landlord forms "guests" definition

[Erin Zenger]

We just got the BP landlord forms and I was looking through the lease and noticed that the "Use of Premises" section has a very specific, (yet vague) amount of time for people to be in the house as guests before they need to be on the lease. 

In the NY forms it says, "Tenant may permit guests to stay with Tenant in the Premises for up to ten (10) days. Any guest staying with Tenant for longer than ten (10) dats shall be considered an occupant of the Premises." 

I didn't quite know how to take that. Would that be 10 days consecutively, monthly, annually? 

Any insight is appreciated.

Thanks!
