Across the country, accessory dwelling units (ADUs) are on the rise. And that’s not just because of the global pandemic, which has many of us yearning for extra space as we work from home and navigate shelter-in-place orders. Changing legislation and more progressive policies across the U.S. have made them easier to build as a way to address the affordable housing crisis.

While many ADUs are converted garages or backyard structures that have been adapted to include a kitchenette and bathroom, it’s also possible to purchase a prefabricated ADU and install it on your property—just make sure to check your local jurisdiction for regulations on size, location, and materials. With an eye on affordability and exciting design, we’ve gathered seven ADUs that come in under $100,000 before costs of permitting, shipping, and utility hookups.
