Accessory Dwelling Units (ADUs)

Accessory dwelling units are one of the smartest investments a Kitsap County homeowner can make — whether you’re creating rental income, housing an aging parent, or building a home office with real separation from the main house. At Bluefoot Architecture & Design, we specialize in ADU design that navigates local zoning codes, maximizes livability in compact footprints, and creates structures that complement your primary residence rather than looking like an afterthought bolted onto the property.

What our ADU design services include:

Our ADU Design Specialties

Detached Cottages

Standalone ADUs designed as complete homes in miniature — full kitchens, private bathrooms, dedicated entries, and outdoor living space. We design cottages that feel like intentional architecture, not converted sheds or prefab boxes.

Garage Conversions

Converting an existing garage into a permitted dwelling unit is often the fastest and most cost-effective ADU path. We handle insulation upgrades, egress requirements, kitchen and bath plumbing, and interior design for comfortable year-round living.

Above-Garage Units

Building a living unit above an existing or new garage maximizes your lot without consuming yard space. We engineer the structural requirements, design efficient stair access, and create upper-level floor plans that feel spacious despite compact dimensions.

Attached ADU Suites

In-law suites and attached ADUs connected to the main home with their own private entry. Ideal for multi-generational living — close enough for daily connection, separate enough for independence. We design the transition zone so both households have privacy.

Rental-Optimized ADUs

ADUs designed specifically for rental income — durable finishes, efficient mechanical systems, soundproofing between units, and layouts that attract quality tenants. We help you understand the ROI and design decisions that maximize long-term rental value.

Add Value to Your Property

Washington state has made ADU permitting easier than ever, and Kitsap County properties are well-positioned to take advantage. We’ll assess your lot for ADU feasibility — setbacks, utilities, access, and zoning — then design a unit that fits your goals, whether that’s rental income, family housing, or a dedicated workspace. Every ADU we design meets current code requirements and is built to last.

Our ADU Design Process

Every ADU project follows a five-phase process tailored to the unique regulatory and site constraints that come with building a secondary dwelling on an existing residential lot.

ADU design involves navigating zoning overlays, setback calculations, utility connection requirements, and sometimes HOA restrictions that don’t apply to standard new construction. Our process accounts for all of these variables upfront so permitting goes smoothly.

Whether you’re building a 400-square-foot studio cottage or a 1,000-square-foot two-bedroom unit, our process ensures every square foot is optimized for livability and code compliance.
