REVIEW YOUR BOTHELL PROPERTY
Start with the home, yard and service connections you already have. Bothell crosses county boundaries, so confirm the property's jurisdiction and providers before comparing a basement apartment, garage conversion or separate backyard home for family.
Bothell's checklist distinguishes utility providers and county health approvals. Establish water, sewer or septic responsibility before choosing bathrooms and bedrooms.
Place easements, hard surfaces and drainage routes alongside the proposed ADU. Keep a practical route to the original home and its outdoor areas.
An interior apartment, a unit above a garage and a detached dwelling solve different privacy needs. Compare everyday entry routes before selecting the form.
Bring the address and existing plans. Confirm the applicable jurisdiction before planning your Bothell project.
BUDGET FOR YOUR BOTHELL PROJECT
Utility availability, existing structures and drainage can influence a Bothell ADU's scope. Establish the site work, professional responsibilities and interior selections before reviewing a written proposal for your particular property.

Area planner only. Construction pricing for Bothell follows review of the property, design, site work, fees, allowances and taxes in your written proposal.
Review the Bothell scope ↗A compact dwelling still needs a complete construction scope. Review the existing house, new living areas, access, service connections and finish selections together, with allowances and exclusions recorded before work.
| Scope item | What your proposal should clarify |
|---|---|
| Design & engineering | Architect and engineering responsibilities, site documents, and any designer’s plan-license fees. |
| Permits & City fees | Applications, review fees, required permits and who is responsible for each cost. |
| Site preparation | Existing structures, demolition, excavation, access, drainage and any site-specific work. |
| Utility connections | Water, sewer, electrical service, connection routes and any required upgrades. |
| Interiors & selections | Cabinetry, surfaces, flooring, fixtures, appliances and the allowances for your selections. |
| Taxes & changes | Tax treatment, exclusions, payment milestones and how changes are priced and approved. |
The floor area is a planning input. Confirm the complete Bothell project scope, exclusions and total price before construction.

THE SEATTLE DESIGN COLLECTION
Browse 183 entries in the Seattle ADUniverse reference collection, including 31 with drawings, documents or layout galleries. Compare proportions and room arrangements for ideas. Seattle's program does not establish approval in Bothell; your site, current city requirements and designer licensing need their own review first.
These 10 designs are listed as pre-approved in Seattle’s gallery. Site-specific permitting and a plan license from the designer are still required.
No designs match these filters. Try another size or search term.
We’ll help you explore access, site conditions, layout and construction for your property.

START WITH YOUR PROPERTY
Compare the independence of a separate cottage with the potential of existing space. Let the property's verified conditions and the household's routines guide the choice.
Tell us about your propertyCreate a separate entrance and living environment, with utilities, drainage and the relationship to the main home planned from the beginning.
Add living space beside the house while resolving entrances, shared walls and the effect on the existing floor plan.
Investigate a basement or garage before assuming it is ready for residential use. Building condition and service capacity shape the next step.
FROM YOUR BOTHELL ADDRESS TO HANDOVER
Move from property information to a defined design and construction scope. Each stage resolves questions for the next; site conditions, permit review and selections shape the schedule.
Identify jurisdiction, utility providers, existing buildings and the household the ADU will serve.
Compare layouts, entrances and outdoor relationships with the appropriate design professionals.
Coordinate Bothell's required plans and supporting information, then respond to review comments.
Connect site work, services, structure and interior finishes with inspections and clear project updates.
Review the finished work, required approvals, operating information and project documentation together.
The design team, reviewing authority, site conditions and material lead times shape your Bothell sequence. We refine milestones as the documents and permit path become clear, then confirm the construction schedule in the agreement.
BEFORE YOU BEGIN
Clarify the service boundaries, existing space and permit information that can affect your Bothell property before moving deeper into design.
Ask us your questionNo. Identify the property's actual service providers. Bothell's ADU checklist refers to city and district utility services and county health review for septic properties.
Start with the parcel information and a sketch locating the house, other structures, access, easements and utilities. Bothell's current checklist identifies the formal submittal documents.
Existing use alone does not establish approval. Bothell describes an application and inspection route for previously unapproved ADUs; the building official determines the work required.
No. The city describes attached units, homes above garages and detached ADUs. Compare the existing building's potential with the privacy offered by a separate structure.
Your Bothell price is developed around the selected layout and property review. The written proposal should identify design responsibilities, site preparation, utility connections, finishes, allowances, exclusions, fees and taxes. The area planner on this page does not calculate a construction price.
