Sometimes referred to as a carriage house, accessory dwelling units (ADUs) are structures found on the same ground or are attached to single-family houses. It might be an apartment set over the garage, an apartment in the basement with a separate entrance, or a stand-alone house occupying the backyard. Recently, these structures have become especially popular and are being built for various reasons, including to gain income through rent or to house an aging family member. As a smaller and self-sufficient home, ADUs have basic bathroom facilities, a kitchen, an eating space, a sleeping space, and a living space. 

In Denver, these units have become especially common as real estate prices continue to rise. This list of the best accessory dwelling unit builders in Denver features local professionals with the ability to adapt their designs and management processes according to the client’s needs.
