Learn moreWhy decks in Denver need a little more planning
Older homes, older decks. The median home in the city of Denver was built in 1975, according to the Census Bureau's American Community Survey (ACS 2024 5-year). The city has about 718,877 residents and a median home value of $616,000. Many decks on homes that age are decades old, so repair and replacement quotes are common.
Frost, snow and sun. The 2025 Denver Building Code sets a 36-inch frost line and a 43 psf ground snow load, and decks must carry the greater of the live load or snow load. Denver International Airport averages about 156 nights a year at or below 32 °F (NOAA 1991–2020) and the city gets about 47 inches of snow a year (NWS). UV exposure rises with elevation (EPA), and Denver sits at 5,280 feet.
Hail. Colorado sits in "hail alley," with about 7–9 hail days a year (NSSL). The May 8, 2017 hailstorm was Colorado's costliest insured event (NWS Boulder).
Denver deck permits in brief
Most decks over 12 inches off the ground need a zoning permit; decks 30 inches or more above grade, decks over 200 sq ft, and all covered decks, porches and pergolas also need a building permit. Rules change; confirm with Denver Community Planning and Development. Fees are based on project value and double (minimum $100) for work started without a permit. Historic districts and landmarks also need a Certificate of Appropriateness. In the suburbs, Parker requires a permit for every deck. The contractor you hire normally pulls the permit. This is general information, not legal advice. More in Denver deck permit rules.
