Required parking for the ADU may not exceed one space per bedroom. The ADU shall be exempt from parking requirements if located within 1/2 mile walking distance of a public transit station. When a garage, carport, or covered parking structure is demolished in conjunction with the construction of an accessory dwelling unit or converted to an accessory dwelling unit, the local agency shall not require that those off-street parking spaces be replaced. (Gov. Code, §65852.2, subd. (a)(1)(D)(xi).
