Garage Conversion Cost in Denver, Colorado
In Colorado, converting a garage into a living space or Accessory Dwelling Unit (ADU) has become a primary solution for addressing the state's housing shortage and increasing property value. With the 2024 passing of House Bill 24-1152, many Colorado municipalities are now required to streamline the approval of ADUs, making it easier than ever for homeowners in Denver, Boulder, and Colorado Springs to repurpose underutilized square footage. This guide details the critical local requirements—from high-altitude insulation to radon safety—needed to ensure a successful conversion in the Centennial State.

Frequently Asked Questions
Do I need a permit for a garage conversion in Colorado?
Yes. You will typically need a building permit, electrical permit, and plumbing permit. If you are creating a full ADU with a kitchen, zoning approval is also required to ensure compliance with density and setback laws.
How much does a garage conversion cost in Colorado?
A basic single-room conversion typically ranges from $15,000 to $25,000. A full ADU conversion with a kitchen and bathroom generally costs between $50,000 and $150,000 depending on the finishes and structural needs.
Is slab insulation required for Colorado garage conversions?
Yes, if the space is to be heated. Local codes often require R-10 perimeter insulation for the concrete slab to prevent heat loss and frost heave during Colorado's frigid winters.
Can I convert my garage into a bedroom in Denver?
Yes, provided you meet egress requirements. In Colorado, a bedroom must have a window of at least 5.7 square feet that is low enough for emergency exit, and you must install smoke and carbon monoxide detectors.
