State Rules for Mill Creek
Mill Creek is a Tier 3 city (2020 population about 20,900). State law requires the city to allow at least 2 homes on residential lots inside the urban growth area. Transit-based increases in state law do not apply to Tier 3 cities, although the city's own code may allow more in some zones.
Covenants Come First
Before any design, we read:
- The subdivision's CC&Rs (covenants, conditions and restrictions)
- HOA architectural review requirements
- Any recorded limits on the number of dwellings per lot
Some older covenants restrict a lot to one single-family dwelling; others are silent. The answer decides whether a duplex is practical or whether the project is better aimed at a lot outside an HOA.
Where Mill Creek Projects Work
- Lots outside HOA control — older parcels on the city's edges and annexed areas.
- Lots near the Swift Orange Line — the line ends at McCollum Park and connects Mill Creek to Lynnwood City Center light rail. Parking requirements cannot be imposed within a half-mile walk of its stations.
- Larger lots where a cottage-style pair of small detached homes suits the neighborhood character better than an attached building.

Mill Creek FAQ
QCan my HOA stop a duplex?
Possibly. Private covenants are contracts between owners and are separate from zoning. If your CC&Rs limit lots to one dwelling, the HOA may be able to enforce that. We flag it during the lot review.
QIs Mill Creek a good place for rentals?
Rental demand is steady, but HOA rental restrictions are common. Owner-occupied duplexes and for-sale townhomes are often the better fit here.
