Understanding ADUs
An Accessory Dwelling Unit (ADU) is a secondary housing unit on a single-family residential lot. ADUs can serve multiple purposes, such as housing family members, generating rental income, or providing a private space for guests. They come in various forms, including:
- Detached ADUs: Standalone units separate from the main house.
- Attached ADUs: Units attached to the main residence, sharing a wall.
- Garage Conversions: Transforming an existing garage into a livable space.
- Basement Conversions: Renovating a basement to create an independent living area.
Factors Influencing ADU Construction Costs in Denver
Several factors affect the overall cost of building an ADU in Denver:
- Size and Design: Larger units with complex designs will naturally cost more due to increased material and labor requirements.
- Type of ADU: Detached units often incur higher costs compared to attached units or conversions, as they require separate foundations and utilities.
- Materials and Finishes: The choice of construction materials and interior finishes significantly impacts the budget. High-end materials and custom finishes will increase costs.
- Site Conditions: The topography and soil quality of your property can affect foundation work and site preparation expenses.
- Utilities and Infrastructure: Extending plumbing, electrical, and HVAC systems to the ADU adds to the overall cost.
- Permitting and Fees: Navigating Denver’s zoning laws and obtaining necessary permits involve fees that contribute to the total expenditure.
- Labor Costs: Hiring experienced professionals ensures quality but comes at a price. Labor rates can vary based on the complexity of the project.
- Timeframe: A faster construction timeline may require additional resources, potentially increasing costs.

Construction
The construction phase encompasses framing, roofing, siding, and installation of windows and doors. Depending on the size and complexity of the ADU, construction costs can range from $100,000 to $300,000.
Utilities Connection
Connecting the ADU to existing utilities such as water, sewer, electricity, and gas is a significant expense. This process can cost between $10,000 and $30,000, depending on the distance from the main house and the complexity of the connections.
