Nebraska Ground Snow Load: What the Adopted Code Carries

Nebraska adopts the national building code without a ground snow load amendment of its own, so the governing figure for a given address is the one the code's own table carries, and the body that applies it is the county, city or village, and where it has adopted nothing the state building code itself. 17 states are in the same position, which makes it the second commonest arrangement in the country. Nebraska publishes ground snow loads through the county, city or village, and where it has adopted nothing the state building code itself, and the jurisdictions reached for this had put none into a public document at the time they were read.

The county, city or village, and where it has adopted nothing the state building code itself: a local code may set a different standard for local conditions, and where none is adopted the state code applies by default. In its own words: “(b) If a county, city, or village does not adopt a code as authorized under subdivision (a) of this subsection within two years after an update to the state building code, the state building code shall apply in the county, city, or village, except that such code shall not apply to construction on a farm or for farm purposes.”

Nebraska Legislature, Nebraska Revised Statute 71-6403 adopts state building code (Building Construction Act) (International Building Code (IBC), 2018 edition; International Residential Code (IRC), 2018 edition; International Existing Building Code, 2018 edition; Uniform Plumbing Code, 2018 edition). Nebraska adopted it as written. The adopting rule reads: “(1) There is hereby created the state building code. The Legislature hereby adopts by reference: (a) The International Building Code (IBC), 2018 edition, except section 101.4.3 and chapter 29, published by the International Code Council, except that (i) section 305.2.3 applies to a facility having twelve or fewer children and (ii) section 310.4.1 applies to a care facility for twelve or fewer persons; (b) The International Residential Code (IRC), 2018 edition, except section R313 and chapters 25 through 33, published by the International Code Council;”

A ground snow load is a weight per unit area and not a depth, and the two are joined only by the density of the snow on the day, which is why the published documents give the load and leave the depth out. Wet spring snow and dry January snow of the same depth are different weights on the same roof. The county, city or village, and where it has adopted nothing the state building code itself works in loads for that reason, and so does every figure set out below.

The code's figure is applied to a given address by the county, city or village, and where it has adopted nothing the state building code itself. The document behind it is Nebraska Revised Statute 71-6403, State building code; adopted; amendments, published by Nebraska Legislature, read on September 23, 2026. It establishes the point this way: “(2) The codes adopted by reference in subsection (1) of this section and the minimum standards for radon resistant new construction adopted under section 76-3504 shall constitute the state building code except as amended pursuant to the Building Construction Act or as otherwise authorized by state law.”

14 of 50: Connecticut, Indiana, Maryland, Massachusetts, Michigan, Minnesota, Montana, New Hampshire, New Jersey, North Carolina, Rhode Island, Utah, Vermont, Wisconsin. The other 36 split into 17 that adopt the national code without a snow amendment and 19 that leave every figure to a county or city building department. That is the single most useful fact about this subject and no one state's own website carries it.
