Unpacking Boulder's New ADU Construction Rules

In this video, I delve into the specifics of Boulder's ADU construction guidelines. Whether you're considering building an ADU or investing in Boulder's real estate market, this post offers valuable insights into navigating the city's updated ADU policies. Stay informed and ahead of the curve in Boulder's dynamic real estate environment.

 
An ADU is an additional dwelling unit that has separate kitchen, sleeping, and bathroom facilities. It can be attached or detached from the principal dwelling unit on a single-family lot.
 
You MUST receive a permit to build and license an ADU. Learn more and apply HERE
 
ADUs are allowed in the following zoning districts, provided the lot size is 5,000 square feet or greater:
  • RL-1 or RL-2 Residential - Low 1 or 2
  • RE Residential - Estate
  • RR-1 or RR-2 Residential - Rural 1 or 2
  • RMX-1 or RMX-2 Residential - Mixed 1 or 2
  • A Agricultural
  • P Public

For years, there was a 20% saturation limit for ADUs, but as of Sept. 1, 2023, there are no saturation limits. Anyone in the above zoens can build an ADU.

Properties with ADUs must have at least one owner living on site, either in the ADU or in the principal unit. The property must be the owner’s principal residence, which means the owner must live there for more than half the year.
