California State Laws — Complete Reference

California has some of the most distinctive state law in the United States. It was the first state to adopt no-fault divorce (1969), the first to legalize medical cannabis (Prop 215, 1996), and the first to legalize recreational cannabis (Prop 64, 2016). It has among the nation's strongest tenant protections (AB 1482 statewide rent cap, AB 12 deposit cap, just-cause eviction), one of the strictest bans on non-compete agreements (Cal. Bus. & Prof. Code § 16600), and the most comprehensive state consumer privacy law (CCPA/CPRA).

California is also a community property state — one of nine in the US — meaning most assets and debts acquired during a marriage are owned equally by both spouses. It uses a large body of specialized codes (Civil, Corporations, Family, Vehicle, Penal, Health & Safety, Business & Professions, Labor, and 21 others) rather than a single unified code, so finding the applicable law usually starts with identifying the right code first.

What makes California law distinctive

• Community property — 50/50 division of marital assets and debts by default (Cal. Fam. Code § 760).
• Very strong tenant protections — statewide rent cap (5% + CPI, max 10%), just-cause eviction, one-month deposit limit, mandatory 21-day deposit return with itemized statement.
• Non-competes are generally void under Cal. Bus. & Prof. Code § 16600 — California is the strongest anti-non-compete state in the country.
• Cannabis legal for adults 21+ since 2016 under Prop 64, with a comprehensive regulatory framework via the Department of Cannabis Control.
• Strong plaintiff-side consumer law — the Consumers Legal Remedies Act (CLRA) and the Unfair Competition Law (UCL, Bus. & Prof. Code § 17200) give consumers powerful tools.
• Strict gun laws — assault weapons restrictions, 10-day waiting period on all purchases, background checks on ammunition, magazine capacity limits.
• Highest cost of business operation — $800 minimum annual franchise tax on LLCs and corporations regardless of income, tiered gross-receipts fee above $250K.
• Strong worker protections — high minimum wage, mandatory paid sick leave, paid family leave, ABC test for independent contractor classification (AB 5).
• Prop 65 warnings — the ubiquitous "Warning: This product contains chemicals known to the State of California to cause cancer" labels flow from California's Safe Drinking Water and Toxic Enforcement Act of 1986.
• Consumer privacy leader — CCPA (2018) and CPRA (2020, effective 2023) give California residents access, deletion, correction, and opt-out rights that shape privacy practices nationally.
