Frequently asked

Villa builds prefab detached ADUs. These types of ADUs are not connected to the primary residence and are attached to their own permanent foundation. Our designs are HUD-approved, meaning they’re built to national building code and have a streamlined permitting and inspection process.

For typical residential projects, Villa only builds detached ADUs on properties where there is an existing primary residence.

If you're a developer or owner of a multifamily property, reach out to our team to see if we’re a good fit for your project.


We are not currently able to assist with building a single unit on a vacant lot, with some exceptions:

• If you are looking to build a duplex and an ADU, we can help with that under SB9 legislation. Reach out to our team to learn more.
• If you are a developer or someone interested in building multiple units, reach out to our team to see if we're the right fit for your project.


Our mapping tool is an easy way to see what fits on your property and meets setback requirements. Just enter your address and select an ADU to see it on your lot!


We're not a lending institution, but we can connect you with lenders that specialize in financing for ADUs. Learn more here.


You'll select your desired floor plan from 20+ options. From there, you can customize it with our designer-approved finishes in our Design Studio.

We offer 1, 2, and 3-bedroom units ranging from 450 to 1,200 square feet. Browse our ADUs and get an instant quote in minutes!


No, we work with clients who are looking for a comprehensive, turnkey experience. Our service includes the ADU plus permitting, delivery, site work, installation, utility hookups, and more.

"I was very apprehensive at the beginning but Villa gained my trust and confidence as the project progressed and completed. I would hire them again to build another ADU."

"We had a 750 sq. ft. ADU built in our backyard and it's amazing. The entire process was smooth, but my favorite part was watching the ADU being lifted and placed in our backyard - it was like watching a dream come true."
