Schedule a consultationA smarter way to add space
One space, many possibilities
An ADU is one of the smartest ways to add real value and flexibility to your property — a guest suite, a home office, rental income, or a private space for family. We specialize in ADUs and handle the details that separate a quick add-on from a home that feels intentional.
Why homeowners add an ADU
Room to grow, on your terms
Multigenerational living
A comfortable, independent space for parents or adult children — close, but with privacy.
Rental income
A well-built unit that pays you back over time and adds lasting value to your property.
Home office or studio
Separation from the main house, without the commute — a quiet place to focus or create.
Long-term value
Added square footage, built to the same standard as your main home, that stands the test of time.
Why WellHaus for ADUs
The details make the difference
ADUs come with their own rules — setbacks, utilities, and design constraints. Because we focus on them, we help you understand what is possible on your lot, plan around your budget, and build a unit that matches the quality of your main home, not a compromise.
