ADU Construction in Everett, WA
Licensed design-build contractor for backyard cottages
Based in Granite Falls, we design-build accessory dwelling units for homeowners here. Many yards are tighter than north-county lots, so we start with access, parking, and whether an attached unit or garage conversion is more realistic than a detached cottage.

Start with what the yard can actually take
ADU construction in Everett starts with what the lot allows. Detached cottages still happen, but garage conversions, attached units, and fire separation come up earlier in site review — especially on alleys and shared-drive access. Parking, utility capacity, and neighbor setbacks are the usual pinch points — not Pinterest floor plans.
Incorporated lots use city building and planning review. A handful of nearby parcels with this mailing address are unincorporated county land with a different permit path. We confirm jurisdiction from the address before design work.
The city reviews ADU building permits inside city limits. Unincorporated parcels with this mailing address go through county PDS. Current rules and intake live on Accessory dwelling unit permit handout. Apply through online permitting portal when the lot is in the city. Unincorporated parcels use Snohomish County PDS instead. We confirm which desk has the lot before we draw. Permits handling means we prepare and coordinate the construction application — the city still decides approval and timing. See the feasibility guide.
Site prep on a backyard lot
How owners use a backyard cottage
Why homeowners add a unit
The building is a second unit on your lot. How you use it is a separate decision — and it depends on city rules, not only on construction.
Family and in-law
Parents, adult children, or a caregiver who need a separate door and a bathroom. On a tighter lot, privacy often comes from an attached unit or conversion rather than a cottage in the far back corner.
Long-term rental
A second dwelling leased by the month on land you already own. Durable finishes, storage, laundry, and a clear entry from parking are the construction choices. Landlord licensing stays with you.
Guest stays
Some owners plan short-term listings. That is a use, not a separate Artbrick service. City rules for Airbnb-style stays are separate from the building permit and are not guaranteed by construction.
What usually stalls a backyard cottage
These are the questions that stall projects — not cabinet colors. We put them on the table in the first conversation.
- Will this lot qualify after setbacks, coverage, parking, and utilities?
- Is the parcel inside city limits, or unincorporated county with this mailing address?
- Permit delay or denial after money is already spent on drawings
- Fire separation, electrical capacity, or a garage that was never built as living space
- HOA or neighbor rules that are stricter than zoning
- Living on the lot through a long, noisy build
- Planning a short-term listing that the city may not allow
We handle the construction permit path. We do not license listings, manage tenants, or promise rental income. Read the permit process overview before you compare builders on price alone.

What we build
Detached, attached, and conversion ADUs
Attached in-law units and garage conversions show up more often here than on north-county acreage. A detached unit is still on the table when setbacks, parking, and utilities leave a real pad.
Detached backyard cottage
A backyard cottage with its own foundation. Feasible when the lot still has a buildable pad after setbacks, parking, utilities, and access.
Attached in-law unit
An in-law unit connected to the house. On tighter lots this is often the honest path — fire separation and existing-structure condition decide it.
Garage or basement
A garage or basement conversion where egress, moisture, and city rules allow. Tight yards make this conversation earlier than a wide north-county backyard.
Interior finish inside the unit follows the same standards as our kitchen remodel and bathroom remodel work. Full construction scope also lives on full scope overview.

Questions before you start
Do you design and build the unit, or only construct it?
Artbrick LLC is a licensed Washington contractor (ARTBRL*812B8) based in Granite Falls. We design-build backyard cottages with permits handling — one team from lot review through handoff, not a separate architect, permit runner, and builder.
Which office issues the building permit?
Inside city limits, the city building desk linked above. If the parcel is unincorporated, Snohomish County PDS issues the permit even when the mailing city matches. City applications go through the online portal linked above. A ZIP code is not jurisdiction. We confirm from the parcel, then prepare the construction application for that desk. Approval and timing stay with the jurisdiction.
Can I add a backyard cottage on this lot?
It depends on the parcel: setbacks, lot coverage, utilities, septic or sewer, access, and what already sits on the land. We review the parcel map before anyone invests in full drawings.
What do people in this area use a backyard cottage for?
Most owners add space for parents or adult children, a long-term rental on the same lot, or a guest unit. Short-term listings (Airbnb and similar) are a use some owners want — only where the city allows it, and listing licenses are separate from the building permit.
Does a building permit let me list the unit short-term?
No. Short-term rental rules, owner-occupancy requirements, and listing licenses vary and change. A building permit is not permission to list the unit. We scope construction. You confirm rental licensing with the city. We do not promise income or manage listings.
How do I start a backyard-cottage project?
Call (425) 422-5947 or use the consultation button on this page. Share the address, whether the unit is for family, monthly rental, or guests, and a rough timeline. We follow up on lot fit and inspection milestones before ground breaks. Nearby communities include Marysville, Mill Creek, Mukilteo.
