In this second episode of Built by Insights, Matt Krueger and Ryan Costner dive deep into the topic of Auxiliary Dwelling Units (ADUs), also known as carriage houses or guest suites. Ryan sheds light on the growing trend of ADUs in Colorado, particularly in Boulder County, as new state legislation mandates that all Colorado municipalities must allow ADUs by June 30, 2025. The conversation explores the affordability benefits of ADUs, how they can support homeownership by providing additional income, and their role in making cities more walkable.

They discuss the complexities of zoning, building codes, and the specific challenges faced in municipalities like Denver, Lafayette, and Boulder. Ryan shares real-world examples of projects, including a detailed look at navigating fire separation and mechanical requirements for attached or detached ADUs, especially in areas impacted by the Marshall Fire. Additionally, the episode touches on the variety of purposes ADUs can serve, from supporting multi-generational living to providing affordable housing.

Whether you’re an architect, builder, or homeowner interested in adding an ADU, this episode offers valuable insights into the current landscape and what’s coming down the pipeline for the future of ADUs in the Boulder County area.
