ADU Construction FAQ

What is ADU construction?

Also called a backyard cottage, in-law apartments, and granny flats, ADU additions are separate residential buildings that occupy the same lot as a primary residence. They are an innovative and affordable housing solution.

How much does it cost to build an ADU in Des Moines, IA?

The average cost to build an ADU is between $200 - $300 per square foot but can vary greatly depending on size, materials, and finishes. Send us your specifications, and we’ll gladly provide you with a detailed quote for your project.

Can I build an ADU on my property in Des Moines, IA?

Building an accessory dwelling unit is allowed in Des Moines so long as it complies with zoning code requirements in terms of height, design, parking, and occupancy. We’ll take care of acquiring any relevant permits on your behalf.

How much does an ADU increase property value?

ADU additions expand a house’s square footage, making it more spacious, and therefore increasing its value. If rented out, it may provide additional income too. The exact increase in property value is dependent on size and location.
