Renovate Builders has spent over 15 years building ADUs across Washington. With more than 1,000 completed projects and a team of 25 local professionals, we handle every step of the process – from initial design through final construction. Our work includes navigating Kirkland’s specific permit requirements, coordinating with local utilities, and ensuring your unit meets both functional and legal standards.
Whether you’re looking to create rental income, house family members, or simply add flexibility to your property, an ADU designed and built by our team delivers results that work. We understand Kirkland’s building codes and community requirements because we’ve worked within them consistently.
Building an ADU in Kirkland means finding a partner who understands the full picture – what it costs, how long it takes, and whether the finished product will actually perform. ADU construction Kirkland WA requires materials that stand up to Pacific Northwest weather, skilled execution that meets local code, and thoughtful design that delivers real returns whether you’re renting it out, housing family, or building equity for down the road. Renovate Builders handles everything from backyard cottages and detached garages to basement conversions. Each project is engineered for compliance and built with durability in mind. We source materials that last, manage timelines without cutting corners, and price work fairly so you’re not choosing between quality and affordability. The result works harder for you – whether that’s monthly rental income, flexible living space for aging parents, or a significant boost to your home’s market value when you eventually sell.
Detached ADUs are small, independent units built separately from the main home and are also called “backyard cottages”. Have an underused backyard space? You can make it useful through long-term rentals or multigenerational living with the help of detached ADUs. Call us for site planning, custom design, permitting, and full build.
Attached ADUs share at least one wall or structural component with the main home. We also call them home extensions or garage ADUs, as they are usually built over garages or as side additions. Need a space for in-law suites or flexible rental space with shared utilities? This option is for you that adds luxury and comfort to your lifestyle.
Conversion ADUs are garage or basement conversions. We use existing square footage, like basements, attics, or garages, and transform them into livable units. This option is best for fast turnaround and lower cost-per-square-foot, making it ideal for short-term rental or guest suites.
Kirkland’s zoning landscape allows for well-designed accessory dwelling units, and we build them to work within those parameters while unlocking real value from your property. Whether you’re looking at a studio, one-bedroom, or two-bedroom layout, a detached ADU serves multiple purposes – guest housing, rental income, or space for family members under one roof.
Our builds include full kitchens and private bathrooms as standard, paired with energy-efficient systems that keep utility costs reasonable and appeal to tenants or buyers down the line. The flexibility matters. You can rent short-term through platforms like Airbnb, secure a long-term tenant, or keep it available for family needs. Each approach changes your property’s economics, and a well-built unit supports whichever direction makes sense for your situation.
We handle the Kirkland code requirements so you don’t have to navigate them alone. That means proper setbacks, height limits, parking, and the specific details that determine whether your project moves forward smoothly or gets held up in review. The result is a functional, compliant structure that actually works for how you want to use your land.
Our garage conversion service transforms an underused space into a legal, livable unit. We handle structural retrofitting, insulation, plumbing, and electrical upgrades. Need home offices, rental units, or guest quarters? Garage conversion is your best cost-effective alternative to new builds. Increase usable square footage and get a strong ROI without expanding outward.
Expand your home’s square footage without moving, with our room addition services. Add bedrooms, bathrooms, family rooms, gyms, or office space for your growing family or simple lifestyle upgrade. Our team makes sure that all additions match the existing structure and architecture. Let us help you boost appraisal value and functionality in residential zones.
Second-story additions are perfect for homeowners needing more space without sacrificing yard area. We build up, adding full floors or partial pop-tops to maximize views and living space. This is ideal for land-locked Kirkland WA neighborhoods, delivering a major property value increase while supporting long-term living without relocating.
For added privacy and flexibility, backyard cottages in Kirkland WA are a popular choice. These detached living units, also called DADUs or sometimes referred to as in-law suites (when used for extended family housing). Our team completes them with kitchens, bathrooms, and private entrances. Highly useful for families with aging parents, adult children, or renters. Enjoy living independently while increasing property value and long-term rental income.
ADUs generate consistent passive income through short- or long-term rentals. It’s one of the lowest-barrier ways to invest in real estate without buying a second property or moving out.
And if you do relocate, it’s known that Kirkland WA homes with ADUs consistently sell for more. Buyers value extra rentable space, which means your property stands out in listings.
Adding an ADU gives your property long-term flexibility. Enjoy a livable space for aging parents, adult kids, or a future home office. It adapts to your lifestyle while preserving privacy and personal space.
