Custom Accessory Dwelling Units in Vallejo

Make the most of your backyard space with a custom structure from Backyard Unlimited. Since 2009, we’ve helped thousands of homeowners throughout the Bay Area increase comfort, usable space, and resale value with premium quality ADUs.

What is an ADU?

Accessory Dwelling Units (ADUs) are a popular way to invest in your existing property and are one of the fastest growing forms of housing in California. Recently passed California laws make it easy to add additional living space (like a detatched ADU) to your property – even if it is zoned for single family use.

Learn more about the ADU laws in Vallejo and why you need a trusted contractor to help you with your ADU project.

Benefits of Building an ADU

An accessory dwelling unit is a great way to affordably increase your property’s value since it’s an entirely separate living space. You can fully customize your ADU with the same high-quality materials that you would use in your own home. Everything is built to code and fully-permitted, using building-grade materials designed to last for over 50 years.

We’ve seen our customers find creative uses for their ADUs, including:

  • Housing for families
  • Elderly parents
  • First step for young adults
  • Long-term rental property
