Add a living space onto your Seattle home, creating a cozy new unit that feels like it's always been part of the neighborhood.
Get Your Free EstimateBuilding an Attached ADU in Seattle means we're adding a fully independent living space directly connected to your main house, often sharing a wall or foundation. This includes everything from initial design and permitting to full construction, plumbing, electrical, and finishing touches, ensuring it has its own kitchen, bathroom, and living area. We focus on integrating the new structure seamlessly with your existing home's style and the surrounding Seattle neighborhood, making sure it looks like it belongs, whether your home is a classic Craftsman in Ballard or a mid-century modern in View Ridge.
Our approach starts with understanding your vision and how this new space will serve your family or community. We work closely with you to design an ADU that maximizes your property's potential while respecting local zoning and design guidelines. From there, we handle all the details, coordinating with the City of Seattle's Department of Construction & Inspections (SDCI) for permits and managing the build with our trusted local tradespeople. We treat your home like our own, keeping the work area tidy and minimizing disruption to your daily life.
Attached ADUs are a smart move for Seattle homeowners because they can be more cost-effective than detached units, often sharing utilities and infrastructure with the main house. They're perfect for keeping loved ones close, providing a private space for aging parents, or generating rental income in our bustling city. Plus, with Seattle's current housing market, adding an ADU is a fantastic way to increase your property value and contribute to our community's diverse housing options.
Homeowners often wonder about the impact on their existing home or their property lines. We carefully plan the connection points for utilities and structural elements to ensure your main house remains undisturbed and structurally sound. We'll walk you through the specifics of Seattle's setback requirements and how we'll navigate them to make sure your new ADU fits perfectly within your lot, without encroaching on your neighbor's space. We aim for a harmonious addition that enhances your property and the streetscape.
Attached ADUs are a fantastic way to add living space in Seattle, especially on smaller lots common in neighborhoods like Fremont or Capitol Hill where a detached unit might not fit. By building onto your existing home, you can often save on foundation and utility connection costs, making it a more accessible option for many homeowners looking to expand.
Our city's unique climate, with its consistent rain and occasional wind, means that any addition needs to be built to last. We use materials and construction methods that stand up to Seattle's weather, ensuring your new ADU stays dry, warm, and comfortable year-round. We pay close attention to proper flashing, drainage, and insulation specific to our Puget Sound environment.
Beyond the practical benefits, an Attached ADU helps build community. It allows families to stay together, provides affordable housing options, and adds density in a thoughtful way that respects our existing neighborhoods. It's about making our city more livable and welcoming for everyone, right here in the place we all call home.
