(A) An accessory dwelling unit (ADU) may be a detached building, in a portion of a detached accessory building (above a garage or workshop, for example), or a unit attached or interior to the primary dwelling (an addition or conversion of an existing floor, for example).
(B) ADUs shall comply with the following:
(1) A maximum of 1 ADUs is allowed per lot. The ADU may be internal to the primary residence or a detached, separate unit.
(2) The maximum floor area of the ADU shall not exceed 800 square feet or 75% of the primary dwelling's floor area, whichever is smaller. However, ADUs that result from the conversion of a level or floor (basement or attic, for example) of the primary dwelling may occupy the entire level or floor, even if the floor area of the ADU exceeds 800 feet.
(3) Other development standards. ADUs shall meet the development standards for buildings per the underlying zone, except that:
(a) Conversion of an existing legal non-conforming structure to an ADU is allowed, provided that the conversion does not increase the degree of non-conformity.
(b) No off-street parking is required for an ADU.
(c) Detached ADUs shall contain at least 2 detailed design elements from the list in § 151.126.
(d) ADUs are not included in density calculations.
