Our studio is based here, so ADU construction in Granite Falls starts with a site visit: we walk the lot with you, then confirm which permit office has it.

We walk the lot with you
Being local makes the first visit easy to schedule. On that walk we look at where a unit could sit, how utilities would reach it, and how equipment would get in, and we talk through who the unit is for.
A mailing address is not the same as a city lot. Some nearby parcels share the ZIP but sit in unincorporated Snohomish County, with a different permit desk.
Lots inside city limits go through the city’s Building Services. Unincorporated parcels use Snohomish County PDS. We confirm the office from the parcel, prepare the construction application, and coordinate review; approval and timing stay with the jurisdiction. Read the feasibility guide before the visit if you like.
Preparing the site
Ways to use the unit
Uses we design for
We design the building; local rules decide which uses are allowed.
Living space for relatives
A separate door and bathroom for parents or grown children who want to stay close.
Rental income space
A leased unit with laundry and storage. Licensing and tenant management stay with you, and we do not promise income.
Guest quarters
A spare unit for visitors. Short-term listings depend on local rules, not on the building permit.
What we look at on the first visit
These items decide whether a pad is real, and we check them on site.
- Where could the unit sit within the setbacks?
- How would water, sewer or septic, and power reach it?
- Is the parcel in the city or unincorporated?
- Can equipment reach the build area?
- What existing structures or trees are in the way?
- How will the build affect daily life on the property?
- Are the uses you want allowed?
We handle the construction permit path and the build; listings, tenants, and income are outside our scope. See the permit process overview.
Planning the layout
What fits
Options we can build
After the walk, we narrow it to the options that fit your lot.
Freestanding cottage
A detached unit on its own foundation, placed where utilities and access work.
Addition to the house
An attached unit with its own entry and fire separation from the main house.
Garage or outbuilding conversion
Converting an existing structure where egress, moisture, and the jurisdiction allow.
Interior finish meets the same standards as our kitchen remodel and bathroom remodel work. See ADU construction for the full scope.
Visit, permit, build
The same three steps on every lot, starting with a walk on site.

Questions from neighbors
Can you come see the property first?
Yes. Because we are based in town, a site walk is usually the first step, before any drawings.
My mailing address says the city. Am I in city limits?
Not necessarily. Some parcels with the local ZIP are unincorporated. We check the parcel to find the right permit office.
Do you handle permits?
We prepare the construction application and coordinate plan review. Approval and timing are decided by the jurisdiction.
Can an old shop or outbuilding become an ADU?
Sometimes. It depends on the structure, egress, moisture, and local rules. We look at it on the site walk.
Will you help with rental licensing?
No. Rental and listing licenses are separate from the building permit, and those stay with you.
How do I set up a visit?
