Four code zones across Colorado counties
Colorado counties land in four separate IECC zones. In the county tables of PNNL-33270, written for DOE (2021 county data), 5 counties are IECC zone 4B, 34 are zone 5B, 12 are zone 6B and 13 are zone 7. The B marks a dry zone in DOE's labels, and zone 7 carries no moisture letter. A crew that crosses county lines between zones can face more than one set of window values in a single week.
Window ratings vary inside the state as well. Colorado covers more than one zone on the ENERGY STAR climate zone map (August 2025), and installers confirm the zone for a given county or ZIP code in the official ENERGY STAR zone finder before they name a qualifying product.
Energy code status in Colorado
This section is general information, not legal advice. It summarizes official sources as of October 7, 2026; check the current text of each rule before relying on it.
The Department of Energy's Building Energy Codes Program page for Colorado (checked October 7, 2026) shows "Home Rule" as the current state code for residential buildings, with no effective date, no adoption date and no state amendments listed. DOE names the Colorado Energy Office and the Department of Local Affairs as its contacts for the state.
Window buyers working several Colorado jurisdictions therefore check which code the local building department enforces where each job sits.
Colorado housing by decade
Half of Colorado's housing was built in 1988 or later. Table B25035 (ACS 5-year 2020-2024) gives a median year built of 1988, and table B25034 for the same years shows 39.7% of units built before 1980.
The 1970s were a large building decade. Table B25034 (ACS 5-year 2020-2024) counts 418,095 Colorado units built from 1970 to 1979. A request form that asks for the current frame material and the number of openings tells a crew from the first call what it will remove.
For value filters, table B25077 (ACS 5-year 2020-2024) puts the median owner-occupied Colorado home at $539,400.
Contractor licensing in Colorado
This section is general information, not legal advice. It summarizes official sources as of October 7, 2026; check the current text of each rule before relying on it.
Colorado does not license general contractors at the state level. The Department of Regulatory Agencies' home repair guidance (checked October 7, 2026) says that not all occupations are licensed, naming roofers and general contractors, and tells consumers that county laws may apply and to check with their city before hiring an unlicensed professional.
The roofing contract rules, home solicitation cancellation terms and injury rules for the state are on leads in Colorado.
How Colorado window buyers filter
- ZIP code: the most useful filterFilterA rule that decides which leads a buyer is offered, based on fields such as vertical, sub-type, state, ZIP code, homeownership or accident details. Glossary in a state where the code zone and the local code both change from county to county.
- Number of windows and scope: full replacement or a partial job, since local permit rules can differ by scope.
- Home age: the decade the house was built, which tells a crew what era of opening to expect.
- Homeowner status: only the owner can approve the work.
