Avondale moved to the 2024 codes on 1 January 2026. Its amendments document is published but would not open, so this page does not tell you what the city says about windows. Nearby Surprise adopted the same code year within days and exempts replacement windows that do not alter the rough frame opening, and that tells you nothing about Avondale, because cities on identical editions in this metro have written opposite window rules.

Avondale adopted the 2024 International Code Council family of codes and the 2023 National Electrical Code, with an effective date of 1 January 2026. Before that the city ran the 2018 editions, adopted by Ordinance 1686-319 in March 2019.
