What Makes a Great ADU in Oregon?
Not all ADUs are created equal. A good ADU in Oregon needs to do more than just fit the legal requirements – it should feel livable, efficient, and suit your long-term plans. That means having enough natural light, a smart layout, and materials that can handle Pacific Northwest weather. It also helps to work with experienced builders who understand the permits, zoning, and utility hookups that come with types of dwelling units in Oregon.
In some cases, your accessory dwelling unit may also need to accommodate aging-in-place features or meet specific rental income goals. That’s why design flexibility and upgradable features matter more than ever. With the right plan and builder, your ADU can grow with you – not just meet the bare minimum.

Why Oregon Homeowners Love ADUs
Besides the obvious flexibility, ADUs are becoming a go-to choice because of how they help increase property value without the need to buy more land. Oregon’s statewide support for ADU construction also simplifies the process compared to other states. Whether you’re in Portland or a smaller city, adding an ADU is often less complicated than you think.
Plus, with so many people rethinking how they live and work, ADUs have become popular as home offices, rental units, or even downsizing solutions for aging parents. There are plenty of ADUs that turned out so well, the homeowners moved into them themselves.
