The law requires you to give notice; it does not require you to get permission.

When I give notice, I tell the tenant that I (or the contractor) will enter the home on [DATE] at [TIME] and will be there for approximately [# of HOURS] to complete the work. If tenant wants to be there, they are expected to provide access. If they fail to allow access, they are charged a $100 trip charge fee.

If their schedule doesn't allow them to be there, then I will open the home for the contractor.

I try to respect the tenant's schedule, but I also expect them to respect mine and the contractor's. If they want to live in a well-maintained home, they will comply.
