The City’s municipal code requires that one off-street parking space with an all-weather surface shall be provided for the exclusive use of the ADU, in addition to the parking that is required for the primary dwelling. The parking space for the ADU may be allowed in the driveway and in tandem. However, the parking requirement is waived for certain locations (e.g. if the ADU is located within a designated historic district or within a half mile of a public transit stop), for certain types of ADUs (e.g. when the ADU is part of the existing single-family dwelling or an existing accessory structure) and for ADUs meeting other criteria listed in SMC 19.50.090E. Check with the Planning Department to help determine the requirements for your ADU.
