Rental registration and inspection
Waukegan licenses all rental housing, even owner-occupied buildings of two units or less, at $60 per rented unit yearly; an owner living in the building pays no fee and gets no inspection for that unit.
For investors: Someone buying a Waukegan two-flat to live in one side still licenses the rented side. License and inspection fees are billed by calendar year whatever month the inspection falls in, so carry them in the first-year operating budget.
