Accessory Dwelling Unit (ADU)
Q: What is an ADU?
A: An apartment integrated within a single-family dwelling unit, above a garage located on the single-family lot, or as a detached unit located behind the single-family structure. Accessory dwellings typically have separate bathrooms, eating facilities, living areas, and entrances from the single-family and may or may not have separate utilities and shall not exceed 50 percent of the floor area of the single-family dwelling unit. There shall not be more than one accessory dwelling located on a lot in addition to the single-family dwelling unit and the accessory dwelling shall not be subdivided or sold separately from the single-family dwelling unit.
Effective IMMEDIATELY, the Town of Gypsum is now requiring the permitting of all existing ADUs and are accepting applications for new ADU builds to be constructed. It is of utmost importance to ensure the safety of our community by ensuring proper ADU guidelines and requirements that help protect our residents and homeowners.
