Mukilteo's Baseline
Mukilteo is a Tier 3 city (2020 population about 21,500). Under state law the city must permit at least 2 homes on each residential lot within the urban growth area. The Sounder station counts as a major transit stop, so no off-street parking can be required for middle housing within a half-mile walk of it — but the state's higher unit minimums near transit apply only in Tier 1 and Tier 2 cities.

Paine Field and Other Overlays
Parts of Mukilteo lie under the approach and departure paths for Paine Field. Depending on location, projects may face noise-insulation standards, height limits or disclosure requirements. We check overlays for every parcel.
Projects That Suit Mukilteo
- Stacked duplexes on view lots — each floor gets a full-width view.
- Owner-occupied duplexes with a main home above and a rental below, using a daylight slope.
- Single custom infill homes on difficult lots where two units would require too much structural cost.
Mukilteo FAQ
QIs a sloped Mukilteo lot too expensive to develop?
Not necessarily. Slopes add foundation and drainage cost but often create a daylight level — effectively a second unit — that offsets it.
QWill the ferry terminal count as transit?
No. Washington ferry terminals were removed from the definition of a major transit stop for middle housing purposes.
