BUILDING ADUs IN DENVER
Denver is ground zero for ADU construction in Colorado. In November 2024, Denver City Council voted to legalize ADUs in all residential neighborhoods — no individual rezoning required. That means if you own a single-family home in Denver, you can almost certainly build an ADU on your property right now.
Denver's housing market has been one of the tightest in the country for years. Median home prices remain well above $500,000, and rental vacancy rates are consistently low. ADUs offer homeowners a practical way to generate $1,500–$2,500/month in rental income while helping address the city's housing shortage.
303 Construction has been building across Denver for over 20 years. We know Denver's building codes, its planning department, and its neighborhoods. From Park Hill to Sloan's Lake, from Capitol Hill to Green Valley Ranch, we've built in every corner of this city.
TYPES OF ADUs IN DENVER
Denver's diverse housing stock supports every ADU type. Older neighborhoods like Washington Park and Platt Park are ideal for detached backyard ADUs on larger lots. Bungalow-heavy areas work well for basement conversions. Homes with alley-accessed garages are prime candidates for garage conversions.
