State facts
Nebraska: homes, climate zones and who licenses the work
Nebraska has 863,000 housing units. 57.2% were built before 1980, and the median year built is 1975. 66.5% of occupied homes are lived in by their owners.
How old the homes are
Nebraska housing units, by year built
Layers drawn to scale
Age changes what applies to a house. In general, anyone paid to do work that disturbs painted surfaces in a home built before 1978 must be certified in lead-safe work practices under the EPA's Renovation, Repair and Painting Rule, which the EPA administers directly in Nebraska.

Climate and building zones
The 2021 International Energy Conservation Code assigns every county a climate zone from 1 to 8 and a moisture regime: A for moist, B for dry, C for marine. Zones 7 and 8 have no letter. Here is how Nebraska's residents divide among them, by the county they live in.
| IECC 2021 zone | Share of residents | Counties |
|---|---|---|
| 5A | 100% | 93 |
ENERGY STAR rates windows, doors and skylights for four climate zones of its own. All of Nebraska falls in the Northern zone.
By NOAA's 1991–2020 climate normals, counties here average 143 days a year with a low of 32°F or colder, weighted by where people live. The range runs from 131 days in the mildest county to 208 in the coldest.
