KCC Title 21A grants density bonuses, height increases, and reduced parking when projects in unincorporated King County provide deed-restricted affordable housing or other public benefits.
KCC 21A.34 affordable housing incentives let developers build above the base density when they set aside units for households at or below specified area median income levels for at least 50 years. Bonuses scale with the depth of affordability and apply most strongly within urban growth boundaries near transit. Cities like Seattle, Bellevue, Redmond, and Kirkland run their own Mandatory Housing Affordability or incentive zoning programs that layer on top of state law RCW 36.70A.540.
Failure to record covenants or maintain affordability triggers permit revocation, monetary recapture of the bonus value, and denial of future incentives across King County jurisdictions.
