Frequently Asked Questions
What is an ADU?
An Accessory Dwelling Unit (ADU) is a separate dwelling with its own kitchen, restroom, and optional separate utilities that can be built on your property without subdividing your lot. ADUs are sometimes called granny flats, in-law suites, or backyard homes.
Should I go to an Architect First or Builder First?
ALWAYS get a value build estimate with your trusted builder first, then work with the architect. This way you'll know exactly how much your project will cost and you can break ground confidently with a clear budget.
What are the benefits of building an ADU?
ADUs provide additional living space for family, increase your property value significantly, create potential passive rental income, and offer a smaller place for retirement while renting out the main home.
How much does it cost to build an ADU?
Costs vary depending on the build complexity, desired square footage, whether it's a conversion or new construction, city fees, and finish level. Contact us for a free estimate tailored to your specific project.
Are there zoning requirements for ADUs?
Yes, but California's ADU laws are very favorable. No city can deny an owner the right to build an 800 sqft ADU. We handle the permitting process and work with you to make it completely seamless.
Can I convert my existing garage into an ADU?
Absolutely! In California, homeowners can convert an attached garage into a Jr ADU (JADU) and even build an additional detached ADU on the same property.
How long does ADU construction take?
Depending on your project type, actual construction can take as little as 90 days for a garage conversion to 6-12 months for new construction. We pride ourselves on meeting every deadline.
Are there financing options available?
Yes! We work with many lenders to help homeowners finance their ADU projects. Options include home equity loans, construction loans, and ADU-specific lending programs.
