Background and Analysis:

ADUs are complete, separate dwelling units constructed on the same lot as a single-family home. ADUs are typically small dwelling units and may be a separate building or built by adding onto or converting a portion of a single-family home. The Land Use and Environment Committee (LUEC) directed staff to bring a resolution and agreement to Council for consideration in 2020 to partner with Lacey and Tumwater to develop a set of pre-approved ADU plans. The pre-approved plans now need to be updated to be consistent with the latest construction code updates. Updated plans will also include a 1,000 square-foot ADU design option in response to House Bill 1337 passed by the State Legislature that requires local governments to permit ADUs up to 1,000 square feet. Yelm has asked to be included in the new Interlocal Agreement.

 

This Interlocal Agreement updates and replaces an interlocal agreement for the development of updated accessory dwelling unit (ADU) plans approved last fall. This Interlocal Agreement makes necessary adjustments to hourly rate costs associated with  preparing the ADU design plans.

 

Climate Analysis:

ADUs provide housing that can be accommodated within existing city limits, reducing potential urban sprawl, providing needed infill density to support greater use of transit, and reducing greenhouse gas emissions.

 

Equity Analysis:

ADUs are an additional option for needed housing that are typically more affordable than single-family homes. The provision of pre-approved ADU plans will benefit community members planning to construct ADUs in Olympia by eliminating design costs and significantly reducing permit and plan review fees, and likely making ADUs more available as a housing option in the community. 

 

Neighborhood/Community Interests (if known):

There is significant neighborhood and community interest in the construction of ADUs. Concerns have been expressed about potential impacts to existing neighborhoods of additional housing units and parking.

 

Financial Impact:

The cost for updated ADU plans is $9,808.00 not including taxes. The expected cost to add a 1,000 square-foot ADU option is $31,974.00 not including taxes. Under the agreement, costs are to be split between the jurisdictions based on total population. Olympia would contribute $15,386.04.The City of Olympia contribution can be accommodated within the professional services budget allocation to the Community Planning and Economic Development Department.
