The City of Seattle offers a voluntary “Incentive Zoning” program for new development. In exchange for either building affordable housing, making an in-lieu payment, or providing another amenity from a list of community benefits, the City will allow more gross floor area in a development. In 2022, the program raised more than $800,000 dollars for affordable housing and other public benefits, directly created three affordable housing units, and directly generated other public benefits.
