About Denver ADU Builders

About Denver ADU Builders

Denver ADU Builders is a consulting and construction firm focused on helping homeowners plan and build Accessory Dwelling Units (ADUs) in the Denver area. Their approach is designed to simplify what can otherwise be a complex and time-consuming process, guiding clients from the initial planning stages all the way through to a completed, rentable unit.

Whether a homeowner is looking to generate rental income, create space for extended family, or simply add value to their property, Denver ADU Builders positions itself as a one-stop shop for the entire ADU journey — covering surveys, soils tests, pre-designed architectural plans, permit submission, and connections to property management companies.

The ADU Building Process

Denver ADU Builders has structured their process into clear steps to help clients understand what to expect at each stage:

  1. Select an ADU Option: Clients choose from a set of pre-designed ADU plans suited to the architectural style of their home. These plans have gone through multiple rounds of revisions with experienced builders and architects. Because the plans are already designed, the primary cost to the client is placing those plans on their specific lot survey — saving both time and money.
  2. Financing and Planning: The team walks clients through available financing options, including access to an in-house financing team. This stage also covers anticipated timelines and the best path forward before a deposit is made.
  3. Design and Customization: After a deposit is placed, clients receive a personalized design selection package covering flooring, tile, paint, and fixtures. A designated project manager guides clients through these selections.
  4. Build Process: Once permitting is complete, construction begins. Clients are kept informed throughout the build until the ADU is ready for use or rental.

With over 40 years of building experience in Denver, the team understands the local permitting process and works to move through it as efficiently as possible so their licensed general contractor can begin work without unnecessary delays.

Design Priorities and Benefits of an ADU

Denver ADU Builders designed their standard plans around three core goals:

  1. Maximizing the floor plan: Since costs like water, sewer, and power connections are largely fixed regardless of the ADU's size, building a larger unit helps ensure the best return on investment.
  2. Privacy for all parties: The design features interior staircases accessed from the alley through a one-car garage, keeping the ADU occupant's entry separate from the main home. Windows facing the primary residence are also minimized, and any outdoor space is oriented toward the alley.
  3. Quality and durability: Drawing on decades of experience with home construction and interior design, the materials and finishes selected are intended to be low-maintenance and long-lasting — an important consideration for rental properties.

From a financial standpoint, an ADU can be one of the more cost-effective ways to add rental income or living space, given that the land is already owned. Short-term rentals on ADU properties in Denver have reportedly generated between $4,000 and $7,000 per month in gross income for some clients, while long-term rental rates typically range from $2,220 to $4,000 per month depending on location. For homeowners who need more space but are locked into favorable mortgage rates, adding an ADU can be a practical alternative to purchasing a new property.

Denver ADU Builders serves homeowners in the Denver, Colorado area, offering a structured and guided approach to detached ADU construction and accessory dwelling unit development.

"We worked with Matthew at Denver Custom ADU on two projects across two homes in Denver Wash Park and Sunnyside neighborhoodsan ADU build converting our garage into a beautiful office and fitness space, and a basement renovation. His work was exceptional. From the beginning, Matthew brought a level of clarity and professionalism that made the entire construction process feel manageable. His strong relationships with top, high-quality trades really stood out to us, as well as his responsiveness, communication, and the overall quality of construction. We would absolutely recommend Denver Custom ADU to anyone looking for a skilled, trustworthy ADU builder in Denver."

"Matthew helped me with a complete design build project for a small ADU at our house in Denver. He was involved with everything from the initial design phase, to linking up with an architect, choosing materials finishes, everything. He made the process super easy and transparent. Pricing was fair, build quality was excellent. Timeline was right on schedule. I'd definitely recommend him and would work with him and his crew again!"
