Number of California Bills by Code – 2026 Edition

California’s 29 Codes, beginning with the Business & Professions Code and ending with the Welfare & Institutions Code, contain over 156,000 statutes. Each year, more statutes are being considered through legislation. So, how many bills introduced in the 2025-26 Legislative Session affect these 29 Codes?

In the following chart, I look at the number of bills adding, amending, or repealing sections of California’s 29 Codes during the 2025-26 Session, along with the 2023-24 Session statistics for comparison purposes. The following chart contains those numbers:

Code	Number of Bills in 2025 – 26 Session	Number of Bills in 2023 – 24 Session
Business & Professions	605	632
Civil	504	495
Civil Procedure	295	310
Commercial	22	22
Corporations	101	109
Education	577	644
Elections	137	142
Evidence	112	116
Family	135	187
Financial	88	69
Fish & Game	122	127
Food & Agricultural	114	125

Streets & Highways	128	141
Unemployment Insurance	124	109
Vehicle	273	318
Water	153	184
Welfare & Institutions	575	671

Most interesting to me is the relative consistency each Session with the number of bills affecting the same Code, certainly over the past decade that I have been tracking this data. In other words, during the last decade, roughly the same number of bills each Session affect an individual Code.
