Accessory Dwelling Units (ADUs) Moui�ms ViEw Currently the City of Mounds View allows accessory dwelling units, or ADUs, within a single family dwelling as converted existing floor space, or as an addition to the home with a Conditional Use Permit (CUP). The City does not allow detached, or free-standing, ADUs. FIG. 1 FIG. 2 ADUs are permanent, self-contained residential dwelling units attached to or located within a larger single- family dwelling (home). Also known as "in-law suites" or "granny flats", among others. An ADU must have its own kitchen, bathroom, and sleeping area separate from the primary dwelling. An ADU could be an attic or basement `apartment', a livable space above an attached garage, or within an addition to the home (with a CUP). Unlike a twin home, where two equivalent housing units share a site but are owned separately, an ADU is smaller than the principal home and cannot be owned separately. The owner of the property is legally required to be a resident of either the principal dwelling or the accessory dwelling.
