Entering the Premises

[Gregg Schiff]

We have a tenant that is complaining that we didn't give them proper notice per the lease agreement to enter the premises when all we had was our contractors go in their back yard to remove a couple of window screens.  Is the verbiage 'entering the premises' generally understood as the interior of the property or is entering the backyard generally considered entering the premises?  It's no big deal but the tenant is throwing around that we breached the leasing agreement and if it happens again they will escalate it to the proper channels - whatever that means.
