Is a Detached Accessory Dwelling Unit (DADU) right for your Seattle home?

Do you love your home and your great Seattle neighborhood – but want more room? This year we’ve had more and more Seattle homeowners reaching out to us about building a Detached Accessory Dwelling Unit (or DADU) in their backyard. With changing laws and an increasing focus on affordable housing and density, it’s no wonder folks are excited about the potential a DADU can unlock. At Harjo Construction we too are excited about the flexibility a DADU can provide to a property. In part one of this blog we will share more about the basics and how to get started.

What is a DADU?

A Detached Accessory Dwelling Unit (DADU), also known as a backyard cottage, carriage house, guest house, or mother-in-law unit, is a legally permitted additional unit on your property. A DADU is not connected to your main home, allowing for more privacy and independent space. That means no shared walls, a separate entrance, and potentially even a distinct address. Unlike tiny houses which are often built on wheels, a DADU is considered a permanent structure.

AADU vs. DADU

Accessory Dwelling Units come in two forms: attached (AADU) or detached (DADU). Both must have their own kitchen, bathroom, sleeping area, living space, and entry. The main difference is simply whether or not they are attached to the primary residence. An AADU is most commonly a basement apartment, and connected to your primary home, offering a blend of proximity and privacy. There are benefits to both AADUs and DADUs, and we suggest taking time to think about what option will make the most sense for your property, family, and budget. Once you have a clear understanding of your vision, goal, and parameters, you can choose the best option.

Benefits of a DADU

Different homeowners have different motivations for building a DADU. Here are some themes we’ve seen:

Monetary:

Homeowners who build a DADU on their property can rent them out for additional income, whether they rent it out long-term or list it on a vacation rental site for a short-term lease. Depending on what Seattle neighborhood you live in, you could realize your return on investment much sooner thank you think. A DADU can also increase the property value and many buyers are excited by the flexibility they provide.

Family and Guests:

A DADU can provide a separate space for visiting family and friends, or even older children who are craving independence. It can also help alleviate the crowded, multigenerational living situation that occurs when grandma, grandpa, or an older child moves into the home. Make them feel welcome by creating a fully functional living area complete with a kitchen, bathroom, bedroom, and even a washing machine. This keeps them close to the family while allowing them to retain their independence.

Hobbies:

In addition to kitchens and bathrooms, a DADU is also a great spot for a side-hustle or hobby—think photography studio, writing room, artist loft, or music rehearsal space.

Sustainability:

Building a DADU within Seattle can mean closer proximity to public transportation. Utilizing existing land reduces urban sprawl. Additionally, a DADU is typically smaller size which requires less energy to heat and cool, keeping utility costs low and reducing carbon emissions.

Aging-in-Place:

An intentionally designed DADU with a single story and accessible features like a walk-in shower and wider hallways, make them ideal housing for you or your family as you age. A modern DADU offers all of the creature comforts of home, but with the added benefits of seclusion, privacy, and a garden view.

Is a DADU right for me?

We think now is a great time to explore adding a DADU to your property. Whether you are a homeowner with a multigenerational family, often have out-of-town guests, or are looking towards your future of aging-in-place, building a DADU is a smart, long-term investment. We recommend homeowners check out ADUniverse, which is a great resource for learning about the process in Seattle. They have a tool where you can search for your address to learn about what you can build on your lot and the feasibility of creating a DADU on your property.

Digging into details like zoning regulations, building structure, and the effect on property value is essential. Depending on if your goal is to bring in a new source of income via rental revenue, provide a cozy living area for family, or create a space for your band practice, understanding the unique features, advantages, and drawbacks associated building a DADU is key.

New zoning laws are coming into effect in Seattle soon, which means more flexibility and opportunities. These new rules, designed to increase density and improve the availability of affordable housing will make it much easier for many homeowners to build a DADU. We’ll share more about these new regulations in an upcoming blog post.  If you are thinking about DADUs the best time to start learning more is now and Harjo Construction is here to help.
