Independent living shaped around Arlington properties, family routines and thoughtful construction decisions.
Turn a spare building or a carefully chosen part of your Arlington property into a separate place to live. Start with the parcel, utility connections and everyday access, then shape the floor plan around the people who will use it.
A property-specific proposal begins with your site and intended use.
Share your Arlington address and the way you want the space to work.
REVIEW YOUR ARLINGTON PROPERTY
Start with your Arlington address, existing buildings and the people who need more space. A useful ADU plan brings access, utilities and outdoor living into the conversation before settling on the final building footprint itself.
Plot property lines, existing structures and access before selecting a detached footprint. Check the city's zoning map and any floodplain or critical-area constraints that affect the parcel.
Arlington's ADU code requires city water and wastewater connections. Review the service route with the city before committing to a layout that could require extensive trenching or conflict with existing improvements.
An existing garage may offer a useful starting point, but evaluate its structure, floor height and path to a comfortable entrance. Compare that work with the privacy and outdoor-space implications of a new detached building.
Bring the address and existing plans. Confirm the applicable jurisdiction before planning your Arlington project.
BUDGET FOR YOUR ARLINGTON PROJECT
An Arlington estimate starts with usable building area, service connections and the existing home's condition. Compare conversion work with a detached structure before assigning a budget to the preferred layout.
800 sq ft to review
Area planner only. Construction pricing for Arlington follows review of the property, design, site work, fees, allowances and taxes in your written proposal.
Review the Arlington scope ↗Define the dwelling, site work and connections together. A clear Arlington scope identifies what needs investigation, which improvements serve both homes and how the property will function after construction ends.
| 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 Arlington project scope, exclusions and total price before construction.

THE SEATTLE DESIGN COLLECTION
Seattle's ADUniverse catalog contains 183 entries, with plans available for 31. Explore building forms and layouts as discussion material for Arlington. Catalog inclusion does not establish local approval; your parcel, selected design and proposed services still need review through the appropriate permitting authority before construction.
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.
Seattle’s pre-approved designation is specific to the City’s program. For Bellevue or another nearby city, confirm the applicable local review and approval path.

START WITH YOUR PROPERTY
Compare the construction involved, the yard remaining and the connection each option creates with your existing home.
Tell us about your propertyExplore a detached home where the buildable area, utility route and approach support a genuinely independent entrance.
Extend the main building while planning sound separation, circulation and a useful boundary between households.
Assess a garage or interior area for structure, insulation, ceiling height and the work needed for residential use.
FROM YOUR ARLINGTON ADDRESS TO HANDOVER
Each stage resolves a different set of decisions. The sequence is a planning guide; site findings, review comments and the agreed construction scope determine the schedule.
Confirm jurisdiction, map constraints and examine the existing house, access and service connections.
Test a conversion and new construction against household needs and the available outdoor space.
Develop coordinated drawings and submit the required applications, addressing reviewer questions as they arise.
Coordinate site preparation, construction, utility work and inspections with clear decisions about finishes.
Resolve final inspections, walk through the finished spaces and review the home's operating information.
The design team, reviewing authority, site conditions and material lead times shape your Arlington sequence. We refine milestones as the documents and permit path become clear, then confirm the construction schedule in the agreement.
BEFORE YOU BEGIN
Bring these questions to the first property discussion, then confirm the requirements that apply to your particular parcel.
Ask us your questionThe city code allows ADUs created from existing structures, including garages, subject to applicable review. A garage still needs a building permit and a dwelling-level assessment of structure, insulation, exits and services; its current use does not establish readiness for residential occupancy.
Arlington regulates floodplains and critical areas, and these can affect an ADU's location or feasibility. Check the actual parcel mapping and any required study rather than assuming that either proximity to the river or distance from it answers the question.
Begin with Arlington Community & Economic Development. The city requires an ADU building permit, and its permit page also provides a fire-sprinkler checklist. Confirm jurisdiction first if the property uses an Arlington mailing address outside the incorporated city.
Bring an address, a simple property sketch and the intended use: family housing, a rental or another long-term need. Establish the viable building area, utility route and entrance approach before spending time choosing finishes or fitting furniture into an untested footprint.
Your Arlington 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.
