Based on the provided documentation, there is no specific information regarding the amount of rental income a basement ADU can generate in the Denver Metro area.

The source content focuses exclusively on the structural and financial drivers related to the construction and foundation costs of ADU conversions. It details several key factors that influence the initial investment for a basement ADU in Denver, including:

• Soil Conditions: The presence of expansive clay soils may require helical pier stabilization or tiebacks to manage lateral soil pressure.
• Structural Requirements: Potential costs for concrete removal and replacement to achieve proper ceiling heights or to repair damaged slabs.
• Building Codes: Compliance with Denver’s 36-inch frost depth mandates and 2026 zoning updates.
• Engineering Needs: The necessity of a licensed structural engineer to evaluate whether an existing basement can support additional living loads.

While the guide helps homeowners understand the basement ADU conversion cost in Denver, it does not provide data on market rental rates or potential return on investment (ROI) through rental income.
