California has long stood apart from the rest of the country when it comes to non-compete agreements. While most states let employers restrict where former workers can go next, California treats these restrictions as fundamentally incompatible with its commitment to employee mobility and open competition. If you’re an employer drafting agreements, an executive being asked to sign one, or a founder evaluating risk during a sale, understanding California’s rules is essential — and the law has only grown stricter in recent years.
This guide breaks down what California permits, what it prohibits, and the limited situations where post-employment restrictions can still hold up.
California’s Default Rule: Non-Competes Are Void
The starting point is Business and Professions Code Section 16600, which declares that “every contract by which anyone is restrained from engaging in a lawful profession, trade, or business of any kind is to that extent void.” California courts have read this statute broadly for over a century.
That means a typical post-employment non-compete — the kind that says a worker can’t join a competitor for one or two years after leaving — is unenforceable in California, even if the employee voluntarily signed it and received valuable consideration. Courts have rejected ‘narrow restraint’ exceptions that other jurisdictions accept.
Recent legislation has gone further. SB 699 and AB 1076, both effective January 1, 2024, make it explicit that non-competes are void regardless of where or when they were signed. An employer based in Texas, for example, cannot enforce a Texas-law non-compete against a California-based employee.
The Limited Exceptions Where Non-Competes Are Allowed
California recognizes three narrow statutory exceptions to the ban. Outside these, courts will not enforce post-employment restraints.
1. Sale of a Business
Under Section 16601, an owner who sells the goodwill of a business or sells substantially all of their ownership interest may agree not to compete with the buyer within the geographic area where the business operates. The buyer is paying for goodwill that would be worthless if the seller immediately reopened next door. Properly drafted, these clauses are routinely upheld and are a common feature of transactions involving the transfer of ownership and goodwill.
2. Dissolution of a Partnership
Section 16602 allows partners to agree that, upon dissolution or upon a partner leaving the firm, the departing partner will not carry on a competing business within a defined area. The scope and structure of the underlying joint ownership arrangements between business co-owners will determine whether the clause is enforceable.
3. Dissolution of or Disassociation from an LLC
Section 16602.5 mirrors the partnership rule for LLCs. A member who sells their interest, or whose interest is terminated upon dissolution, can be bound to a reasonable non-compete tied to the territory the LLC served.
Each exception requires careful drafting. The sale must be genuine, the geographic scope must be tied to where the business actually operates, and the duration must be reasonable. Sloppy language can collapse the entire restraint.
What About Non-Solicitation, NDAs, and Trade Secrets?
Many employers confuse non-competes with other restrictive covenants. The distinctions matter.
- Customer non-solicitation. California courts have largely treated post-employment customer non-solicits as void non-competes in disguise.
- Employee non-solicitation. Once considered permissible, employee no-poach clauses are now likely unenforceable after AMN Healthcare v. Aya Healthcare (2018).
- Confidentiality and NDAs. Legitimate NDAs that protect actual trade secrets remain enforceable. They cannot be drafted so broadly that they effectively prevent someone from working in their field.
- Trade secret protection. California’s Uniform Trade Secrets Act provides robust remedies — including injunctive relief and damages — when a former employee actually misappropriates trade secrets.
Tailoring confidentiality and IP-assignment language to focus on information that genuinely needs protection — without crossing into a backdoor non-compete — is one of the most common workstreams for counsel handling proprietary information and brand protection matters.
The New Notice Requirement Employers Must Take Seriously
AB 1076 created an affirmative duty that catches many out-of-state employers by surprise. By February 14, 2024, employers were required to notify in writing — by individualized communication to each affected current or former employee — that any non-compete clause in their agreement is void. The notice obligation applied to anyone employed after January 1, 2022.
Failure to comply isn’t just a paperwork issue. AB 1076 designates a violation as an act of unfair competition under Section 17200, opening the door to civil penalties, attorney’s fees, and injunctive relief. Employers who simply ignored the requirement remain exposed today.
Practical Implications for Founders and Executives
For California companies, the practical question isn’t whether you can lock employees down — you can’t. It’s how to protect what matters without relying on unenforceable restrictions. This is a common concern for owners of smaller California companies navigating workforce and compliance issues. A practical approach generally means:
- Designing strong, narrowly scoped confidentiality agreements
- Implementing clear IP-assignment provisions in every offer letter
- Restricting access to sensitive information through internal controls
- Using equity vesting and deferred compensation to align long-term incentives
These foundational protections are typically built into a company’s structure from the start, which is why early planning with experienced advisors who guide founders through entity setup and early-stage operations pays dividends. Companies preparing for outside funding should also review how restrictive covenants will be viewed by institutional investors evaluating governance and risk during financing diligence, and ongoing operational questions often surface for businesses working with a trusted outside legal advisor providing day-to-day business guidance.
When Disputes Arise
Even with the strictest ban in the country, disputes happen. A former employer may threaten litigation, send a cease-and-desist letter, or interfere with a new hire. California provides remedies for employees on the receiving end, including declaratory relief and tortious interference claims. On the employer side, the lawful path is typically a claim arising from broken commercial commitments or violated agreements tied to a valid confidentiality or trade-secret obligation, not a non-compete. The same is true when shareholder or member disputes implicate restrictive covenants — careful analysis of the underlying governing documents that define rights between owners of a corporation is critical before any enforcement step.
Building Compliance Into Your Operations
Whether you’re a small employer or a multi-state company with California-based staff, the smart approach is the same: audit existing agreements, scrub unenforceable language, deliver the AB 1076 notice where it still applies, and design future agreements that comply from the outset. Many companies use this moment to revisit their broader commercial agreement framework and template documents. For owners weighing entity changes, this work pairs naturally with guidance on how a company is structured and governed under California law, and for newer companies still finalizing how they’re set up, it’s the right moment to address during the process of getting a new entity properly established under state requirements.
Frequently Asked Questions
Are non-compete agreements legal in California?
No. Under Business and Professions Code Section 16600, post-employment non-compete agreements are void in California, with limited statutory exceptions tied to the sale of a business or dissolution of a partnership or LLC.
Can my employer enforce a non-compete I signed in another state?
Generally no. SB 699 and AB 1076 make clear that non-compete clauses are unenforceable in California regardless of where they were signed or which state’s law was chosen in the contract.
What restrictive covenants are still enforceable in California?
Confidentiality and non-disclosure agreements protecting actual trade secrets remain enforceable, as do IP-assignment provisions and non-competes tied to the sale of a business, dissolution of a partnership, or termination of an LLC interest.
What happens if my employer asks me to sign a non-compete anyway?
Asking a California employee to sign an unenforceable non-compete may itself violate the law. AB 1076 treats inclusion of a void non-compete in an employment contract as an act of unfair competition, exposing employers to penalties and attorney’s fees.
Can I sue a former employer for trying to enforce a void non-compete?
Yes. California employees can seek declaratory relief, injunctions, and damages when a former employer attempts to enforce an invalid non-compete. Tortious interference claims may also be available if the former employer pressures a new employer to rescind an offer.
How can a California business protect itself without a non-compete?
Businesses can rely on well-drafted confidentiality agreements, IP-assignment clauses, internal information controls, equity-based retention tools, and the Uniform Trade Secrets Act, which provides strong remedies when a former employee misappropriates protected information.
