What shapes a project in Flagstaff
Local conditions worth knowing before scope and budget are set.
A large share of apartments and attached homes
The 2020-2024 American Community Survey counted about 32,000 housing units in Flagstaff, with a median year built of 1992. About 42 percent are single-family detached homes, about 9 percent are attached and about 31 percent are in buildings of five or more units. About 28 percent were built before 1980.
Snow, frost and cold design values
Flagstaff's amendments to the 2018 codes set a 60 pound-per-square-foot ground snow load, a 115 mph wind design speed, a 30-inch frost line depth and a 4 degree winter design temperature, and require ice barrier underlayment. Roofing must be Class A or B material, and wood shingles and shakes are deleted. Coconino County falls in climate zone 5B.
Wildland-urban interface rules
Flagstaff adopted the 2006 International Wildland-Urban Interface Code with amendments in March 2008. Ignition-resistant construction tiers include non-combustible roof coverings, and the code also sets fire access and defensible space requirements. The city's building code page still lists its 2019 adopted codes as current, and city handouts say it is preparing to adopt the 2024 codes.
