What is an ADU or MIL?

When the structure is detached from the home it is typically referred to as a Mother-in-Law apartment (MIL), when detached, it is referred to as an (ADU) Accessory Dwelling Unit.

Both can be similar as far as what is included in the design. However, one basic difference is the connections of utilities. An ‘ADU’ will typically have totally separate hookups for water, sewer, gas and electricity, whereas, an ‘MIL’ will have these all connected to the homes systems.
