ADU Construction Denver

Denver allows ADUs on most residential lots zoned for single-family or multi-family use. Key requirements: maximum size 1,000 sq ft or 50% of primary home (whichever is less), must match architectural style of main home, setbacks of 5 feet minimum, one parking space required (waived within 1/4 mile of transit), owner-occupancy required for one unit, and separate utility meters recommended. Denver updated ADU regulations in 2021 to encourage construction. Peak Builders handles all permitting and ensures full compliance with Denver zoning code.

ADU construction in Denver takes 6-12 months total: design and permitting (2-4 months), site preparation and foundation (2-4 weeks), framing and rough-ins (4-6 weeks), finishes and inspections (6-8 weeks). Garage conversions are faster at 3-5 months. Basement ADUs take 4-6 months. Denver permit processing currently takes 8-12 weeks. Peak Builders manages the entire process and coordinates all trades to minimize delays. Weather can extend timelines for exterior work during winter months.

Denver allows four main ADU types: (1) Detached ADU - standalone structure in backyard, most flexibility in design, $150K-$350K; (2) Garage Conversion - convert existing garage to living space, most affordable option, $80K-$150K; (3) Basement ADU - convert basement to separate unit, requires egress windows, $50K-$120K; (4) Attached ADU - addition to existing home, shares wall with main house, $120K-$250K. Peak Builders specializes in all types and helps you choose the best option for your property and budget.

Yes, you can rent your Denver ADU for long-term tenants. Denver requires owner-occupancy in either the main home or ADU. Short-term rentals (under 30 days) are allowed only if you live on the property and obtain a short-term rental license. Average rental income for Denver ADUs: $1,500-$2,500/month for a 1-bedroom, $2,000-$3,500/month for a 2-bedroom. Many clients offset their ADU construction costs within 5-7 years through rental income. Peak Builders can connect you with property managers specializing in ADU rentals.

Separate utility meters are recommended but not always required for Denver ADUs. Benefits of separate meters: accurate tenant billing, easier expense tracking, better resale value, qualifies for certain financing. Costs: electric meter ($1,500-$3,000), gas meter ($2,000-$4,000), water meter ($3,000-$8,000). Xcel Energy and Denver Water have specific requirements for ADU connections. Peak Builders coordinates all utility connections and helps you decide whether separate meters make financial sense for your situation.

Yes, ADUs typically increase Denver property values by $100,000-$200,000 or more, often exceeding construction costs. Denver real estate data shows homes with ADUs sell for 20-35% more than comparable properties without. Additional value factors: rental income potential (cap rate analysis), separate living space appeals to multigenerational buyers, housing shortage in Denver increases ADU demand. ROI is typically 70-100% of construction costs in immediate property value increase, plus ongoing rental income. Peak Builders designs ADUs that maximize both functionality and resale value.
