Council reviews Recode Kent housing code audit and early design options as state middle-housing laws take effect

Council members received a technical briefing and early policy direction on the Recode Kent housing code update, a multi-phased project to align Kent’s development regulations with new state law and the city’s comprehensive plan.

The presentation (led by city planners and consultants from Framework, including Tyler Quinn Smith and Emily) reviewed an audit of existing code against state requirements — including HB 1110 (middle housing), HB 1337 (ADU provisions), HB 1293 (design-review standards) and HB 1220 (shelter/transitional housing provisions) — and proposed a regulatory framework that uses simplified zone consolidation, scalable density rules and targeted incentives to encourage certain development outcomes.

Why it matters: The state’s middle-housing and ADU laws require cities to permit multi-unit housing types on lots traditionally zoned for single-family homes. The council’s direction will shape where and how duplexes, triplexes, fourplexes, townhouses, stacked flats and cottage/courtyard configurations are allowed in Kent, and the city must implement the changes within state timelines.

Highlights from the audit and draft approach

- Baseline legal requirements: Consultants summarized the state baseline: permit at least six of nine enumerated middle-housing types where required, accommodate ADUs under state rules and adopt clear-and-objective design standards consistent with HB 1293.

- Zone consolidation: Staff proposed consolidating several similar residential zones into a smaller set (proposed labels NR‑1 through NR‑4 in the presentation) so that like standards apply across a manageable set of districts. The change is intended to reduce text duplication and clarify where middle housing will be allowed, and it will require a companion comprehensive-plan amendment.

- Scalable density (two-option approach): To allow a practical path for larger lots and varied lot sizes, the consultants proposed a two-option method. A site could either use a units-per-lot baseline (for example, the mandated four units per lot where applicable) or apply a net-density calculation expressed as units per acre; the rule yields more units on larger lots while avoiding an additional mandatory subdivision step.

- Unit lot subdivision: Staff proposed using unit-lot subdivision as a tool to enable fee-simple ownership of individual units on a larger parent lot while applying site-wide standards (parking, stormwater, coverage) to the parent parcel.

- Modeling and desired outcomes: Framework presented 3D and plan-level tests showing that four units can generally be fit onto minimum lots modeled (5,700 sq ft), though the arrangement is tight. Desired outcomes in the models included retained trees, varied unit sizes, shared open space, efficient floor plates (stacking), and retention of existing housing where feasible. Consultants noted that some middle-housing types (for example courtyard apartments) are less likely to occur due to market and financial feasibility.

- Incentives and trade-offs: To encourage retention of trees and existing houses and to preserve livability, consultants proposed a menu of incentives such as bonus units for tree retention or preserving the existing home, flexible setbacks in certain zones, reduced parking minimums, and limited additional height where appropriate.

Council questions and next steps

Council members raised questions about site feasibility for certain unit types, the limits of private covenants (HOAs) vs. state law for ADUs, impacts on parks and open space, and how inspection and enforcement would interact with occupancy and building-code standards. Staff noted that implementation will include further interdepartmental coordination (public works, fire, building) and additional outreach to developers and permit staff.

Framework and city staff said a detailed memo and regulatory package will follow; the next steps include continuing technical work, public workshops with builders and a proposed code amendment and associated comprehensive-plan amendments in the coming months.

Ending: Council members generally expressed support for preserving canopy trees and for measures that expand ownership opportunities while asking staff to return with specifics on incentives, parking, stormwater impacts and neighborhood-level infrastructure implications.
