2025 Cycle CASE Reports
The Statewide CASE Team selected measures for inclusion in Nonresidential, Multifamily, and Single Family CASE Reports in the 2025 code cycle. At the end of the 2025 code cycle, the Final CASE Reports are replace with Result Reports. The Results Report explains the revisions that occurred to the proposed code changes between the submittal of the Final CASE Report to the CEC and the CEC’s adoption of the 2025 Title 24, Part 6 Standards on September 11, 2024. The Final CASE Reports are included in Appendix 2 of the Results Reports.
The 2025 standards continue to improve upon the 2022 standards for new construction, additions, and alterations to residential and nonresidential buildings.
