Snohomish County, Washington
Construction & land development consulting in Snohomish County
CLD's home county, and the jurisdiction Carol has worked in longest. Snohomish County covers rural acreage, incorporated cities with their own permit counters, and a lot of parcels where the wetland map and the wetland disagree.
Who permits your project here
Unincorporated Snohomish County projects go through Planning and Development Services, which runs its own permit portal for land use and construction applications. Incorporated cities — Everett, Marysville, Lynnwood, Edmonds, Monroe, Arlington, Mill Creek, Lake Stevens, Mukilteo, Snohomish and others — permit independently, and many participate in the shared MyBuildingPermit.com portal.
Confirming which jurisdiction actually has authority is the first step, and it isn't always obvious near city limits or in areas that have annexed recently. Filing in the wrong place costs weeks.
What makes Snohomish County projects distinctive
Large amounts of rural and semi-rural land with septic rather than sewer, which drives ADU and subdivision feasibility more than zoning does. Substantial wetland and stream presence west of the Cascades foothills. Steep slope and landslide hazard areas in the eastern and river-valley portions of the county. Coordination with Snohomish County PUD on service is a routine part of site development here.
The county publishes assistance bulletins covering short subdivisions, rural cluster subdivisions, conditional use permits and more — genuinely useful documents that most applicants never read.
Where CLD spends the most time
Feasibility on rural parcels where septic capacity and critical areas determine yield. ADU siting on lots where setbacks and existing septic drive the answer. Short plats where road and stormwater requirements consume more area than the owner expected. And unsticking permits that have cycled through review more than twice.
Common questions
Do you work in unincorporated Snohomish County and the cities?
Both. The first thing CLD confirms on any engagement is which jurisdiction has permitting authority over the parcel, since the standards and timelines differ.
Can you help with a Snohomish County PDS permit that's stalled?
Yes — it's one of the most common reasons clients call. The first step is pulling the full permit record and reading every correction letter in sequence to identify what's actually blocking issuance.
Is my rural parcel buildable?
Usually the limiting factors are septic feasibility, critical area buffers, and legal access rather than zoning. A feasibility review answers all three.

Feasibility & Due Diligence
The cheapest problem is the one you find before closing. A feasibility review tells you what the parcel supports, what it will cost to get there, and whether to walk away.

Plan review is a conversation with a reviewer who has a checklist and a queue. Projects move when someone reads what's actually being asked and answers it completely.
Read more →Short Plats & Subdivisions
A land division is an infrastructure project with lot lines drawn on it. The layout that maximizes lots on paper is often not the layout that survives review.
Read more →Critical Areas & Environmental
Critical areas don't make a site unbuildable. They make it a different site than the one you thought you were buying, and the difference is worth knowing early.
Read more →Stormwater & Site Development
Stormwater is where small residential projects discover they're infrastructure projects. Getting the requirements right early changes what the site plan can be.

Washington has spent several years loosening ADU rules, and jurisdictions have implemented that unevenly. What your lot allows depends heavily on who permits it.
