What is an Accessory Dwelling Unit?

An accessory dwelling unit, or ADU, is a self-contained, secondary residential living space that resides within your existing property. They are often referred to as "mother-in-law suites" or "granny flats."

ADUs must include their own distinct sleeping area, a functioning kitchen, and bathroom facilities. Some properties create ADUs with garage space or tiny homes in their yard. With the right basement, you can create an ADU that you can use to increase the value of your home, make extra money on the side, and have a space to have guests stay in pure comfort and style.

The team at Better Basements LLC has worked with all of the cities and municipalities in the Boulder County and surrounding areas and are experts at the laws around ADUs.

FAQs About Turning Your Basement Into an ADU

  • How long does a basement transformation take?

    Most full remodels take between 6–10 weeks depending on size and complexity. The permitting process is a bit more complicated when it comes to ADUs, so while the basement may be done, getting it ready to be rented can take slightly more time. 

  • What’s the difference between finishing and remodeling?

    Finishing involves turning an unfinished basement into livable space. Remodeling typically updates an already finished space or adds new features and layouts.

  • Do you handle permits and inspections?

    Yes. We take care of all necessary permits, code compliance, and final inspections.
