(1) A maximum of one ADU may be permitted on a single lot in a residential zone only when it is accessory to a primary single-family dwelling. Lot size shall not prevent the addition of an otherwise compliant ADU subject to all other requirements of this section.

(2) An ADU shall not exceed 800 square feet of floor area, or 75 percent of the primary dwelling’s floor area, whichever is smaller. An interior, attached ADU that comprises 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 ADU is more than 800 square feet.

(3) Detached ADUs shall be located at least 40 feet from the front lot line and shall otherwise comply with applicable side and rear yard requirements.

(4) Detached ADUs shall not exceed the height of the primary dwelling.

(5) Entrances to detached ADUs shall not face the nearest side lot line or the rear lot line unless there is an alley or street abutting on that side of the lot.

(6) Use Prohibition. An ADU shall not be used as a short-term rental. Nothing in this section shall preclude an ADU from use as a long-term rental. (Ord. 2025 § 17, 2018)
