When there are two units within one residence, the number of garbage bags allowed for each residence with a registered ADU doubles. Example: Three bags are allowed for the upper unit and three bags are allowed for the lower unit, for a total of six bags.

The collector will know that your residence is a registered unit by the "N" plate. The "N" plate must be affixed to the front of the house and visible from the road.
