What is an ADU?
An Accessory Dwelling Unit, or ADU, is a small private apartment built on the same lot as an existing single-family home. ADUs may be attached, detached, or remodeled rooms within an existing home. Granny flats, In-law suites, carriage houses, casitas, back yard cottages, and garage apartments are all considered types of ADUs.

Why Add an ADU?
Homeowners add ADUs for many different reasons. For some homeowners it is an income-generating investment. Some enjoy the benefits of multi-generational living. Others realize both the health and economic benefits of caring for loved ones at home, and others invest in an ADU to secure those benefits for themselves in the future. In any case, adding an ADU is an investment.

What Does it Cost to Add an ADU?
The average size ADU is between 500 and 800 square foot. The total cost to add an ADU can be as little as a few thousand dollars or as much as $160,000, or more. Cost depends on the size of the ADU, the choice of materials and amenities, and if it is an addition, or a detached cottage type ADU, or just remodeled rooms in an existing house.

ADU Financing & Technical Assistance
In recent meetings, representatives from public, private, and nonprofit agencies and organizations asked "How many homeowners in the region are interested in adding an ADU?" and "What kinds of finance products and technical assistance programs would support them?" Your participation in this survey will help answer those questions.

Who should answer this survey?
This survey is for all homeowners in the City of Madison and all the cities, towns, and villages in Dane County.
 
Thank you.
