WHAT ARE ADUs?
Tiny houses, granny flats, carriage houses, & in-law apartments
ADUs are separate living units built on a property that already contains a single-family home. There are attached ADUs, or additions to the primary residence, and detached ADUs, or units that aren’t attached to the main house. An ADU can be a separate building, a basement addition, or even an apartment over a garage.
ADUs add extra living space
Whether you need a home office with added privacy, extra space for the kids to play, a secluded sanctuary for art or entertainment or a state-of-the-art fitness area, the EcoCraft team can help design the perfect ADU for your needs.
ADUs add value
ADUs are extremely valuable when it’s time to sell your home. Some studies show that ADUs can increase property values and make homes more desirable to potential buyers, especially those interested in aging-in-place.
ADUs can generate income
ADUs can be an excellent source of short- or long-term rental income as they create sustainable, in-fill housing, especially in areas that are experiencing a severe shortage. Plus, ADUs enhance walkability and accessibility without changing the character of a neighborhood.
