This article summarizes current timing issues and available resources that may affect local reach-code planning. For a general overview of how reach-code timing usually works, see Understanding Reach Code Timing for New Construction.
Current code-cycle status
The 2025 California Energy Code is now in effect. Projects with permit applications submitted on or after January 1, 2026 must comply with the 2025 Energy Code.
For reach-code planning, this means jurisdictions should use 2025-cycle resources when evaluating new Energy Code reach-code options, including current cost-effectiveness studies, model ordinance language, and implementation materials when available.
Reach-code timing
Residential reach-code timing is different right now because AB 130 pauses the regular residential building code update cycle until 2031. As a result, residential reach codes are not following the typical three-year building code cycle at this time.
Nonresidential reach codes are not on the same paused residential timeline. Jurisdictions considering nonresidential reach codes should continue to follow the usual reach-code planning process.
2025 cost-effectiveness study and policy resource availability
The Reach Codes Team is publishing 2025 code-cycle cost-effectiveness studies, model ordinance language, and implementation resources as they become available. These resources help jurisdictions evaluate reach-code options under the 2025 Energy Code.
Currently available 2025 code cycle studies:
Single family new construction
Existing single family retrofits
Existing single family AC to HP
Existing nonresidential AC to HP and alterations
All of these studies have results available on the Cost-Effectiveness Explorer.
Currently available Explorer policy options:
Existing single family retrofits (FlexPath)
More policy options will become available as the code cycle progresses and additional studies are published.

Residential policy note
Some 2025 residential resources are available, although AB 130 restricts many residential reach codes unless an exception applies. Jurisdictions considering residential reach codes should review the restrictions and exemptions in AB 130 and contact the Reach Codes Team with any questions.
