can I add a visitor to a lease?

[Tammy Mason]

I always get great advice from this thread and I am hoping you all can help me with this situation. I have a lease renewal coming up and my tenant informed me they have a friend who will be staying with them for about a month. I am not sure if this warrants the friend being added to the lease or not.

These tenants are wonderful and have been with us for 2 years.

Any thoughts or considerations I need to take into account?
