ADU Construction

Whether you're looking to add living space, create a private space for family, or make better use of your property, Old Mill Construction provides end-to-end ADU construction with thoughtful planning and proven craftsmanship.

​

From initial planning and design coordination through permitting and construction, we help simplify the ADU building process and keep your project moving forward. We build both attached and detached accessory dwelling units, with every project approached around functionality, quality, code compliance, and long-term performance.
