Standout finding: RI's adoption of the 2024 IECC with zero amendments, plus mandatory Electric-Ready Appendices (CH/RK) as of 2025-08-14, makes Rhode Island one of the most current and EV/electrification-forward energy codes in this entire 51-jurisdiction dataset — notable for the solar/EV calculator work.
Adoption model & precedence
- The state code is the baseline; municipalities may enact additional local requirements/amendments.
- AHJ = local building department, applying the statewide 2025 codes + 2024 IECC.
Major cities / counties
| Jurisdiction | Notes | Building dept. |
|---|---|---|
| Providence | statewide code; publishes current-standards page | providenceri.gov |
| Warwick | statewide code; publishes current-standards page | warwickri.gov |
| Cranston | statewide code | cranstonri.gov |
AHJ fallback (when local adoption is unverified)
- State baseline (certain): 2024 IECC (no amendments), 2025 RI Building Codes, mandatory Electric-Ready appendices (eff. 2025-08-14).
- Action: confirm the current NEC edition directly with the Building Code Commission — not conclusively identified in this pass.
