ADUs

Though you may know it better by another name—the granny flat, laneway house, in-law unit, or sidekick unit—the compact and practical accessory dwelling unit can provide homeowners with extra space for kids home from college or parents aging in place, additional income as a rental, or a simple guesthouse. As cities ease building restrictions to boost housing options, the ADU is seeing a huge uptick in popularity.
