Accessory dwelling units (ADUs) are known by many names: in-law suites, guest houses, backyard cottages, or basement or garage conversions, among others. What all ADUs have in common is that they’re a separate living space typically added to a single-family residential lot, and they’re having a moment.
Constructing an ADU could increase your property value while providing rental income or extra living space for a family member. Then again, adding an ADU could be an expensive hassle you live to regret.
