California Labor Laws by Headcount
If you're an employer in California, your headcount is a legal switch. Your company crosses a threshold and new laws apply automatically, no notices are sent. Most startup or small employers find out once they've received a claim or a lawsuit.
What kicks in at each headcount
1+ employees
Must register for CalSavers (or offer a qualifying retirement plan)
Workplace Violence Prevention Plan required for most locations
5+ employees
CFRA leave (12 weeks, job-protected) + Pregnancy Disability Leave
Harassment prevention training required
FEHA discrimination/harassment protections apply
Fair Chance Act (background check/ban-the-box rules) applies
15+ employees
Pay transparency required: salary ranges must be included in job postings
25+ employees
Job-protected leave for crime victims and their family members (domestic violence, stalking, etc.)
50+ employees
Federal FMLA stacks on top of CFRA
ACA employer mandate (federal) applies
75+ employees
California WARN Act applies: 60 days' notice required before qualifying layoffs of 50+ employees
100+ employees
Annual pay data reporting to the state Civil Rights Department (due every May)
As of September 2026: thresholds and requirements are subject to change; always confirm current figures before acting.
Why this sneaks up on founders
You're tracking headcount for runway. Nobody's tracking it for compliance because at 20-80 employees, there's usually no dedicated HR/People Ops person yet. It's a founder or ops administrator juggling five other priorities.
The risk: thresholds get crossed quietly and nobody notices until there's a claim or a lawsuit.
The 3 most common mistakes
→ "We're too small for that." The rules that applied at 10 people don't apply at 30 and several of the most consequential ones (CFRA, harassment training, background check rules) kick in as early as 5 employees.
→ No one owns it. Compliance isn't on anyone's job description, so it falls through.
→ Fixing it after the fact. Retroactive cleanup: backfilling training, correcting a job posting, rebuilding a leave policy is messier and riskier than building it in early.

Should you handle this yourself or call in help?
Under 5 employees → the state sites above are enough for now, though CalSavers and WVPP already apply.
Approaching 25-50 → this is where state and federal law start overlapping (CFRA + FMLA, pay transparency + hiring practices). Worth a professional review before you cross the line, not after.
Past 75-100 → you're carrying reporting and notice obligations. This isn't a solo-research situation anymore.
