About Puget Sound ADU Builders

At Puget Sound ADU Builders, we create functional and cozy tiny homes and ADUs (Accessory Dwelling Units) in Washington. Our company was founded by Tanya Mills and built on a passion for providing high-quality, affordable housing solutions that unite families. With rising costs in traditional housing and care, we offer practical alternatives that allow your loved ones to live independently in comfortable spaces—right in your backyard.

Each ADU is thoughtfully designed to balance modern amenities with the warmth of a traditional home. Whether you're building a private space for aging family members, a rental unit, or adding value to your property, our homes are the perfect solution.

  • Tanya Mills

    Founder of Puget Sound ADU Builders

    Tanya Mills, a proud Washington native with over 30 years of business experience, has always recognized the transformative potential of Accessory Dwelling Units (ADUs). Her journey began in 1998 when she added an ADU to her first home, discovering its value as both a smart investment and a way to keep families connected. This experience inspired her vision of ADUs as more than structures—they’re opportunities for connection, freedom, and versatility.

  • Expand Living Space

    An ADU is perfect for hosting guests, family members, or even providing a private workspace.

  • Generate Rental Income

    A detached or attached ADU can be used as a rental unit, offering a steady source of additional income.
