Does your lease require written notice?Quoting cannonfodder
The requirement of a month's notice comes from California law, not from their lease form, so I doubt that you could make anything of the space being blank. Some tenants may want to give longer than 30 days notice, for example.Quoting cannonfodder
It would normally be at your regular rental rate. Does the lease provide for any sort of increase?Quoting cannonfodder
