Why Build

Why Homeowners Are Building ADUs in Bothell

Accessory Dwelling Units offer a smart way to adapt your property to changing needs while increasing its long-term value.

Bothell homeowners often choose to build an ADU for the following reasons:

Multi-generational living

ADUs create comfortable, private living spaces for aging parents, adult children, or extended family—while keeping everyone close.

Rental income potential

A well-designed ADU can generate long-term rental income or serve as a short-term rental, helping offset mortgage costs.

Flexible use of space

Home offices, guest suites, and private studios are increasingly common uses for ADUs as lifestyles evolve.

If you’re considering an ADU in Bothell, our team can help you evaluate feasibility, zoning, and design options with clarity and confidence.
