In California, there are specific labor rules that set clear boundaries around how much a minor can work in a week. These rules differ depending on the age of the minor and whether school is in session. They’re not just technicalities—they exist to protect young workers from being taken advantage of or being put in situations that might interfere with their health or school performance.

What the Law Says When School Is in Session
Once the school year begins, the time a minor can spend on the job is trimmed down. That’s intentional—it helps make sure work doesn’t come at the cost of education or rest.
Here’s how it breaks down:
For 14- and 15-year-olds:
- No more than 3 hours a day on school days.
- A cap of 18 hours during any school week.
- Work must take place between 7 a.m. and 7 p.m.
- They can’t work during their school hours, even if they’re ahead in class or on independent study.
For 16- and 17-year-olds:
- They’re allowed to work up to 4 hours on days when school is in session.
- On weekends or holidays during the school term, they can work up to 8 hours.
- There’s a 48-hour total weekly cap when combining work and school time.
- Their shifts must be wrapped up by 10 p.m. on school nights, though they can stay on the job until 12:30 a.m. before non-school days.
This setup keeps school as the main focus and avoids piling on too much responsibility during the week.
What Changes During School Breaks
When summer vacation, spring break, or winter holidays come around, the state gives minors a little more room to work longer hours. With school out of the picture, it’s assumed they have more flexibility.
If the minor is 14 or 15:
- They can work up to 8 hours per day.
- They’re limited to a 40-hour workweek.
- Between June 1 and Labor Day, their shifts can go as late as 9 p.m.
If the minor is 16 or 17:
- The limit goes up to 8 hours per day.
- They can work up to 48 hours a week.
- Work hours can fall between 5 a.m. and 12:30 a.m.
These extended hours recognize that teens may want to take on summer jobs, earn extra income, or gain job experience without academic pressure.
Getting a Work Permit Is Not Optional
Anyone under 18 working in California needs a work permit. No exceptions, even for jobs that seem casual or part-time. The school the minor attends is responsible for issuing the permit, and it lays out what kind of work the minor can do and how many hours they’re approved to work.
Here’s what the process looks like:
- The employer fills out a “Statement of Intent to Employ a Minor and Request for Work Permit.”
- A parent or guardian signs the document.
- The minor takes the signed form to school for review.
- If everything checks out, the school issues the permit.
This paperwork has a purpose—it protects the minor, helps the school monitor attendance and academic progress, and ensures employers follow the law.
Jobs That Are Off-Limits
Just because a teenager is eager to work doesn’t mean every job is up for grabs. In fact, there are strict restrictions on what types of work a minor can legally perform.
The state doesn’t allow minors to do jobs that put them in high-risk situations. Some examples of banned work include:
- Driving vehicles on public roads.
- Working with or near explosives.
- Operating industrial equipment or power tools.
- Working in sawmills or logging sites.
- Performing roofing or excavation tasks.
Even if the teen has the time and the desire, these job types are considered too dangerous. Safety comes first.
There Are a Few Exceptions
California does allow a few exceptions, but they’re closely watched. A minor might be able to work longer hours or outside normal restrictions if they fall under certain categories, like:
- Emancipated minors, who have been legally freed from parental oversight.
- Those working for their parents, especially in family-run businesses, though even these minors can’t be assigned hazardous work.
- Actors, musicians, and performers, who have their own rules and need a different type of permit.
In these cases, the work hours and conditions might look different, but additional paperwork and oversight usually come with it.
Breaking the Rules Comes With Consequences
When employers don’t follow these guidelines, they open themselves up to fines and legal trouble. The state can step in with penalties, especially if the employer is found to have knowingly overworked a minor or allowed them to do work that’s not permitted.
Penalties can include:
- Fines that grow with each violation.
- Investigations from labor authorities.
- Loss of eligibility to hire minors in the future.
- Lawsuits, especially if the minor is hurt on the job.
It’s not just about avoiding trouble—it’s about treating young workers with care and respecting what the law requires.
How Federal and State Laws Work Together
The U.S. Department of Labor sets baseline rules through the Fair Labor Standards Act (FLSA), but states can choose to apply tighter restrictions—and California often does. If federal law allows one thing but California law is stricter, employers in California must go with the stricter rule.
This means that national chains or companies with operations in several states can’t assume the rules are the same across the board. In California, the state’s own guidelines take the lead.
What Employers Should Keep in Mind
Hiring a minor comes with responsibility. Employers need to do more than just get a signature and add someone to the schedule. They should:
- Check the age and school enrollment of the applicant.
- Confirm a valid work permit is in place before scheduling any shifts.
- Keep track of work hours to make sure they stay within legal limits.
- Assign duties that fall within permitted categories for the minor’s age.
- Know the school calendar and understand when certain rules shift—like during breaks.
A little bit of planning goes a long way in staying on the right side of the law.
In Summary
Minors in California are allowed to work, but the law draws firm lines around how many hours they can spend on the job. These rules change depending on age, whether school is in session, and what kind of work is being done. During the school year, 14- and 15-year-olds can work up to 18 hours a week, while 16- and 17-year-olds can work up to 48 hours (including school time). During vacations, younger minors can work up to 40 hours and older minors can still go up to 48 hours, within specific time limits.
Whether you’re an employer, a parent, or a student looking to earn extra money, it’s important to know what’s allowed. These rules help keep teens safe, protect their school performance, and give businesses a clear path for compliance. Staying informed is the first step toward responsible hiring.
