Housing Code Amendments

Snippets of duplex, adu and triplex in Olympia

What's happened?

The City of Olympia adopted changes to codes in order to increase residential building capacity and the variety of housing types allowed in Low Density Residential Zoning Districts. These changes went into effect on December 23, 2020.


The City plans for where and how Olympia will grow and what is needed to serve that growth (parks, open spaces, infrastructure, streets, public services, etc.) under the Washington State Growth Management Act (GMA). The GMA was amended in 2019 and again in 2020 to encourage cities to take steps to increase residential building capacity in urban growth areas. The updated GMA (RCW 36.70A.600) provides a list of options to do so.
