Your home, expanded with purpose-built flexibility.
An Accessory Dwelling Unit (ADU) is more than just extra square footage—it’s a smart, lifestyle-enhancing investment. Whether you’re building a private suite for family, generating rental income, or transforming underused space, we design and build ADUs that feel like they’ve
always belonged.
At E&E Construction and Remodeling, we’re your start-to-finish ADU builder—offering
design, permits, and full ADU construction under one roof. From a detached backyard ADU to
a sleek garage conversion, we help you unlock the potential of your property with clarity,
craftsmanship, and care.
