PRESENTATIONS 1 Accessory Dwelling Unit Code Kaelene Nobis 60 MIN. Amendment Kaelene Nobis, Senior Planner, along with Matt Hutchins from Cast Architecture, presented the Accessory Dwelling Unit Implementation. Nobis explained what an ADU is and what they look like. Information was provided on how to reduce the barriers for residents to building ADUs. The City received a Housing Action Plan Implementation Grant of $80,000 and followed up by selecting Berk Consulting and Cast Architecture to assist with the project. Hutchins walked the Council through: ADU options The neighborhood analysis Barriers to new ADUs Options relating to Size Height Design Guidelines Fees Building Permit and Impact Fees Ownership Ownership Occupancy Requirements City Council Workshop Workshop Regular February 7, 2023 Meeting Kent, Washington Minutes ......................................................................................................................................................................................................................................................................................................._............................................................................................................................................................................................................... Parkin • The current code was reviewed and new options were provided Quantity The number of ADUs per parcel were reviewed Council provided feedback on the potential policy direction for detached ADUs and suggested correlating the ADU size to the lot size, while keeping in mind how larger units might impact the community. Nobis walked the council through the matrix she provided that included cities that adopted ADU code provisions. Council discussed the provision regarding the correlation to the main home and considered not having the ADU taller than the main home or allowing for it to be up to 10' taller than main home. Council discussed the Design Guidelines and suggested changing the guidelines to overall aesthetics and possibly removing the required roof pitch matching to allow for modern slope and flat roofs. Council discussed the fees and whether to reduce fees or eliminate the fees and consider impact fees paid already with the main home, as the ADU is subordinate. Additionally, Council discussed allowing the applicant to decide if they want a separate water meter. Council discussed removing the Owner occupancy requirement. Council discussed parking and potentially considering instances in which the City might consider exempting parking and/or facilitating onsite parking with more flexibility. Council discussed not wanting to increase demand of street parking, providing a list of conditions and possibly allowing a garage to count as stalls. Council discussed circumstances the Council would be interested in allowing more than one ADU per lot. Nobis advised of the next steps that will include: Outreach Survey Tabling Mailing The planned adoption will be either May 16th or June 6th in order to meet the June 15, 2023 deadline. ...........................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................

Accessory Dwelling Units (ADUs) are also referred to as y g =- - mother-in-law apartments. An ADU is a self-contained residential unit that is an accessory use to a single-family home. An ADU is located on the parcel with the primary single-family home and is subordinate in nature. An ADU contains all the basic facilities needed for living independently from the primary residence such as a kitchen and bathroom. An ADU can be configured in different ways such as being attached to a single-family home, above a garage, or detached from the primary residence.
