Quirks & watch-items
Quirks & watch-items
- Connecticut is one of the strictest statewide adoption models — local jurisdictions CANNOT amend the code
- OSBI and Codes & Standards Committee are responsible for all code updates
- 2026 edition in development based on 2024 I-Codes
- NEC adoption note: the 2022 CT SBC references the **2020** NFPA 70 (NEC), not 2023 — the 2023 NEC will not be adopted in CT until the 2026 CT SBC takes effect
