What Is An Accessory Dwelling Unit (ADU)?
An accessory dwelling unit (ADU) is a small dwelling on the same grounds as, or attached to, a single-family house. For example, it could be an apartment over the garage, a basement apartment, or a stand-alone house in the backyard. An ADU can be used to house a family member or for additional income through rent.
How Much Does an ADU Cost?
The cost of building an ADU depends on the design—for example, whether it will be detached from or attached to the main house and what materials and contractors will be required. Another cost implication is that adding an ADU to a property is likely to increase the homeowner’s tax bill, possibly eliminating a significant amount of any rental income.
Does an ADU Add Value to Your Home?
ADUs are popular because, in many cases, they add value to a property. However, how much value they add depends on the market, and the amount is difficult to calculate. A property owner may not know whether an ADU is a good investment until they sell the property.
However, an ADU adds value in other ways that should be considered. An elderly family member who lives in an ADU may place great value in the ability to live in their own home rather than an assisted living facility. Alternatively, a younger family member may appreciate living at home until they are more financially independent.
Does an ADU Require a Kitchen?
The rules for ADUs and what type of kitchen they require will depend on where you live. Consult your local housing and community development administration. It is also a good idea to use a contractor who knows the local zoning rules and requirements for ADUs.
