Attached or detached
Attached space can shorten utility runs but changes the primary house. Detached space creates separation while adding foundation, access and site-development work.
ADU contractor in Everett, WA
Grizzly builds attached and detached ADUs in Everett with coordinated site work, foundations, framing and exterior construction. Everett’s current rules, separate utility expectations and new pre-approved design program make early parcel testing valuable before choosing a plan or assuming a backyard location will work.
Using Everett’s current ADU rules without skipping parcel feasibility
Everett updated its ADU regulations in 2025 and 2026 and defines an ADU as subordinate living space under 1,000 square feet. Zoning may support an ADU while setbacks, lot coverage, site design, utilities and construction access still narrow the workable options.
The City’s pre-approved designs can reduce building-design uncertainty, but they do not make every plan fit every lot. Compare the selected footprint with alley access, existing garages, easements, private yard requirements and the routes for water, sewer and power.
What this project can include
- Detached backyard cottages
- Attached ADU additions
- Foundations and site work
- Framing and exterior completion
What changes the project cost?
The useful estimate is based on the site and scope, not a generic square-foot number.
- Separate water, sewer and electrical service work
- Detached foundation and constrained backyard access
- Site design or frontage conditions tied to the parcel
- Interior layout, accessibility and finish selections
What changes the schedule?
Planning, access, review and construction conditions determine the sequence.
- Parcel feasibility before selecting a plan
- Permit and utility review under current City guidance
- Demolition or relocation of existing accessory structures
- Foundation and weather-tight shell before interior trades
Permits and local planning
Everett’s current ADU page addresses allowed locations, design and utilities, and the City offers pre-approved designs. Each unit still needs the applicable residential permit, and utility requirements can be substantial. Verify zoning, lot coverage, yard, access and service connections for the parcel.

Decisions to make before adus begin
Map utilities first
Locate water, sewer or septic, power, stormwater and existing easements before fixing the building location. Utility feasibility can change the best ADU concept.
Plan for long-term use
Accessibility, privacy, storage, parking and sound separation should reflect who may live there over time, not only the first expected occupant.
ADUs questions in Everett
Does Grizzly handle an ADU in Everett?
Yes, subject to project fit and scheduling. Start by sharing the property address, the outcome you want, current-condition photos and any drawings or permit records. Those details help separate a workable construction scope from assumptions that still need City or engineering review.
Do Everett’s pre-approved ADU designs eliminate site planning?
No. They can simplify the building-plan component, but the chosen design still must fit setbacks, lot coverage, access, utilities and other parcel requirements. Foundation and site work remain address-specific.
What permits apply to an ADU in Everett?
Everett’s current ADU page addresses allowed locations, design and utilities, and the City offers pre-approved designs. Each unit still needs the applicable residential permit, and utility requirements can be substantial. Verify zoning, lot coverage, yard, access and service connections for the parcel.
What should I share for a useful Everett estimate?
Share the address, approximate dimensions, access photos and the existing condition. Also flag separate water, sewer and electrical service work, detached foundation and constrained backyard access, site design or frontage conditions tied to the parcel. A site visit can then verify quantities, elevations and the work that belongs in the construction sequence.
