Building an ADU (Auxiliary Dwelling Unit) or a DADU (Detached Auxiliary Dwelling Unit) is a popular option for Seattle area homeowners right now. In an effort to improve housing accessibility, the City of Seattle passed legislation making it easier to build detached housing (think mother-in-law apartments) or separate entry basement apartments. With economic opportunity growing here in Rain City, we continue seeing an influx of residents. So we must keep finding new ways to increase our housing to keep pace. One of the reasons that these spaces have become so popular is because for a small space, you can see relatively large return depending on your use case.

ADU’s are self contained living spaces within an existing single family dwelling, typically including their own kitchen, bathroom and separate entrance. DADU’s are the same, simply detached from the property’s main house. In the City of Seattle, ADU’s are limited to 1,000 square feet in a single-family zone and 650 square feet in a lowrise zone. If you are curious about the requirements you can check out your local jurisdictions building departments website or give us a call, chances are we will know what the requirements are for your location.

Whether you are looking for an extra source of income via rental space, or simply housing a family member, we can help you come up with a custom ADU design that best fits your needs. We understand that the purpose for building this additional living space may flex over time.We will work with you every step of the way to create a space that has the highest level of functionality possible. You and your family are diverse, and we want to help create an environment tailored specifically to you and your needs.

More than just a company bent on profit maximization, we are a customer-driven firm that believes in the value of hard-work, and lasting relationships. We've been building community and professional relationships for the past 19 years, based on our underlying philosophy that offering honest help to the client is what allows for success.

Our home remodeling efforts focus on delivering environmentally sustainable works, built for the future, that not only work to improve the aesthetic value of your home, but its market value as well.


At Better Builders, we are forward thinking, hardwired to act on your behalf, and in your best interest. We design and build for longevity and in some cases, pre-plan this space for future mobility and access requirements. We'll work within your budget and time frame, and only wrap-up when we have completed a project we can both be proud of.  Here's what we offer with all of our home improvement services:

  • Personal care and assistance every step of the way. We develop a relationship with each client individually, in order to address what it is you're specifically looking for in a remodel, and how we can achieve it. We have built a solid team of support staff to be there for you through every step of the process.
  • Providing affordable service. We don't believe in a philosophy built on maximizing personal gains at the expense of our customers. We are a customer-driven firm that believes in the value of hard work and lasting relationships. When we build, we do so with your interests in mind, and work within your budget.
  • Versatility in Design. Whether you're looking for cabinets, counter-tops, sinks, or everything and more, Better Builders is able to accommodate and adapt to your specific needs. We design for your style and functionality, not our own personal aesthetic.

This means we're committed to making sure you get a fantastic looking home, but that it's also environmentally sustainable and built to last. As a Built Green member we share the mission to promote environmentally friendly home building methods and practices, and to enhance our communities through leadership in sustainable development.
