Garage Conversions & ADUs in Denver
Denver's ADU-friendly zoning makes garage conversions one of the most strategic home investments available. A finished ADU can generate rental income, house family members, or add a private workspace — all without expanding your footprint.
Red Remodels manages the entire process: zoning review, architectural drawings, permit submission, construction, and final inspection. We've completed conversions ranging from simple studio units to fully outfitted two-bedroom ADUs.

Framing & Insulation
Structural framing for walls, ceilings, and partitions plus proper insulation to meet Denver's energy code and keep the space comfortable year-round.

New electrical panel circuits, lighting, outlets, and plumbing rough-in for bathrooms and kitchenettes — all licensed and permitted.

Our Garage Conversion Process
Free Estimate & Zoning Review
We assess your garage, review Denver's ADU requirements for your property, and provide a detailed written estimate with design options.
Design & Permits
We prepare architectural drawings and submit for building permits with the City of Denver — typically a 4–8 week process we manage for you.
Construction
Framing, insulation, mechanical rough-ins, drywall, flooring, fixtures, and finishes — completed with inspections passed at each required phase.
Certificate of Occupancy
We pass the final inspection and obtain the certificate of occupancy. Your new space is legal, livable, and ready to use or rent.
Garage Conversion Cost in Denver
Costs vary based on garage size, desired use, and finish level. Here's what Denver homeowners typically invest:
- Basic home office or studio (no plumbing)$25,000 – $50,000
- Guest suite with bathroom$50,000 – $90,000
- Full ADU with kitchen & bath$80,000 – $150,000+
Denver's ADU permitting process adds cost and time but creates a legally permitted space that adds to your home's appraisal value. Rental income often offsets the investment within a few years.
