§ 154.281 ACCESSORY DWELLING UNIT STANDARDS.
   (A)   A maximum of one accessory dwelling is allowed per legal single-family dwelling. The unit may be a detached building, in a portion of a detached accessory building (e.g. above a garage or workshop), or a unit attached or interior to the primary dwelling (e.g., an addition or the conversion of an existing floor).
   (B)   A detached accessory dwelling shall not exceed 900 square feet of floor area, or 75% of the primary dwelling's floor area, whichever is smaller.
   (C)   An attached or interior accessory dwelling shall not exceed 900 square feet of floor area, or 75% of the primary dwelling's floor area, whichever is smaller. However, accessory dwellings that result from the conversion of a level or floor (e.g., basement, attic, or second story) of the primary dwelling may occupy the entire level or floor, even if the floor area of the accessory dwelling would be more than 900 square feet.
   (D)   An accessory dwelling shall have a minimum size that conforms to the International Building Code.
   (E)   Separate sewer lines shall be provided for each detached dwelling unless an existing detached accessory structure is already connected to the sewer system.
   (F)   Off-street parking shall be provided as required in § 154.337.
   (G)   Conversion of an existing legal non-conforming structure to an accessory dwelling is allowed, provided that the conversion does not increase the non-conformity.
   (H)   Each dwelling unit shall have a separate address.
