Why Build an ADU

Is an ADU Right for Your Sammamish Property?

Accessory dwelling units have become one of the most valuable and flexible home investments in Sammamish. Whether you’re planning for family, rental income, or future flexibility, an ADU can unlock new potential in your property.

Homeowners often consider building an ADU when they need:

Space for family or guests

ADUs provide private, comfortable living spaces for aging parents, adult children, or long-term guests—without sacrificing independence.

Additional rental income

A well-designed ADU can generate consistent income while increasing the overall value of your Sammamish home.

A flexible long-term investment

ADUs adapt over time—serving as a home office, guest suite, rental unit, or future downsizing option.

If you’re exploring ADUs in Sammamish, our team can help you evaluate feasibility, design options, and long-term value with clarity and confidence.
