Accessory Dwelling Units

ADUs are one of the best ways to future-proof your home. Whether you have family members who need a place of their own, want privacy for house guests, or look to rent out your additional space, an ADU can be the right choice for your home.

Whether you’re just starting to think about your future in-law suite or have plans for a granny unit already, reach out to us below to find out why Jubilee is Sonoma County’s #1 choice for custom tiny home and accessory dwelling unit building.

ADUs in Sonoma County

  • An ADU, or Accessory Dwelling Unit, is an additional attached or detached home on your existing property. Sometimes called Granny units or in-law suites, these are typically under 1200 square feet, and are self-contained with their own kitchen and bathroom(s). California laws passed over the last few years have made it easier than ever to build an ADU: now almost any lot qualifies for some kind of ADU construction.

    Jubilee Building has built a curated list of trade partners and personnel with ADU construction specifically in mind. Our team is sized and priced for the optimal construction timeline and costs for ADUs and small single-family residences. Our team knows exactly how to make it happen.

  • ADUs are a great way to bring your family together into one place while maintaining independence and privacy. They also add a lot of value to your lot, and can bring in valuable monthly rental income. With the ongoing shortage of housing, ADUs are a great way to build your home’s value, while doing your part for the community at large.

  • Jubilee offers pre-priced ADU designs and finishes packages. These save you from the time and headache of making the hundreds of decisions that building a custom home requires. However, if you need something off-standard or have a particular vision for your home, we’re more than happy to work with you to build your dream ADU!

    We’ve built tiny ADUs under 400 ft², to grand 1200 ft² granny units. Jubilee has built over 10 ADUs since we started in 2022, ranging from garage conversions, above-garage ADUs, junior ADU additions, and fully detached in-law suites. Our turnaround is typically 4-6 months, depending on scope.

“Jubilee Building turned our 400 square foot garage into an ADU (Accessory Dwelling Unit). This was a full renovation; including all foundation, framing, electrical, plumbing and finish work. Andy and all of his staff did an excellent job from the beginning of the bid process through the end of construction.”
