About DL Engineering Inc.

ADUs and Denver's Housing Landscape

Denver, Colorado has seen significant population growth in recent years, attracting young professionals, families, and retirees. This growth has put pressure on the city's housing supply, with property values rising and traditional housing options becoming harder to access for many residents. Accessory Dwelling Units (ADUs) have emerged as a practical response to this challenge.

ADUs — also referred to as granny flats, in-law units, or carriage houses — are secondary housing units located on the same property as a primary residence. They can take the form of detached structures, attached additions, garage conversions, or converted spaces within an existing home. Most range from one to two bedrooms, offering functional living space for a range of occupants.

There are several reasons why ADUs have become an increasingly relevant option in Denver:

  1. Increased housing density without consuming additional green space or requiring demolition of existing structures
  2. Lower construction costs compared to full-sized homes, which can translate to more affordable rental rates
  3. Flexible use cases, including rental units, multigenerational living arrangements, home offices, or artist studios
  4. Reduced resource consumption, as smaller units generally require less energy and materials to build and maintain
  5. Neighborhood compatibility, when designed thoughtfully to complement the existing architectural character of the area

Key Considerations Before Building an ADU in Denver

Anyone considering an ADU project in Denver should be aware of several important factors before moving forward.

Zoning and regulations: Denver has specific ADU regulations covering size restrictions, placement on the property, and design guidelines. Understanding these rules early in the process helps avoid permitting delays and ensures the project meets city code requirements.

Design and structural planning: Working with a qualified architect and structural engineer is an important step. Professionals experienced in ADU design can help navigate regulatory requirements, determine appropriate sizing and layout, and confirm that the structure meets safety and integrity standards.

Construction expertise: Selecting a contractor with experience in ADU construction is essential. Familiarity with local building codes and safety standards contributes to a smoother build process and a compliant finished product.

Financing: Various financing options may be available for ADU projects, including traditional bank loans, private lenders, and potentially government grants or incentives depending on individual eligibility.

"Not thrilled. When I get an estimate I assume that it will include what I need to complete my project. I feel like I have been nickel edand dimed over and over again. i respect that I am paying for engineering expertise, but I feel like because I was provided a junior engineer, his lack of knowledge has resulted in me paying more and my project being delayed. I thought I was paying for people that knew the codes. Most recently, I was told he didn't know them and it would cost more for him to study the IRC codes referenced by permitting. Who knew that water barrier and fire protection are "architechural"? My contractor had used them with a senior engineer before and did not have a problem. Maybe a stronger mentorship program is needed. They reached out to me and helped to progress the project. I appreciate their willingness to help."

"In a world of incompetent city building departments, DL Engineering and Austin Duffy are a shining light. I have been rebuilding my home personally, and they have been the only consistently reliable partner throughout the entire journey. For a great price too. They will always find a way to make something work, and give dozens of alternatives should the initial idea fall flat. I will be hiring them for any future projects or concerns."
