California Non-Compete Law: Section 16600 Void Rule and the Section 16601 Sale-of-Business Exception

Are non-competes enforceable in California? Generally no. A California non-compete is usually void because Section 16600 voids contracts that restrain someone from a lawful profession, trade, or business. Section 16601 is the exception that matters in a sale of business: a buyer may enforce a seller covenant tied to purchased goodwill when the clause matches the business sold, territory, and scope.

If you are buying a California target, the phrase "California sale of business non-compete" usually means one specific worry: you know California bans most non-competes, but your APA still needs the seller to stay out of the business you are buying.

That instinct is mostly right. California starts from a broad anti-restraint rule. But a real sale of a business is different from a routine hiring-side restriction. Business and Professions Code Section 16601 preserves a sale-of-business carve-out where goodwill or the seller's full ownership interest is part of the deal.

For an ETA searcher mid-LOI or mid-APA, the point is not "California non-competes never work." The better question is whether the clause is drafted like a buyer-protection covenant tied to purchased goodwill, or like a broad restraint that tries to control the seller beyond the business being sold.

Section 16600 vs Section 16601

California's Baseline: Section 16600

Business and Professions Code Section 16600 is the baseline. It says that, except as provided in the same chapter, contracts restraining someone from a lawful profession, trade, or business are void to that extent.

For the broad California non-compete question, that means the default answer is no. General employment non-competes and clauses that function like employment non-competes are usually void, even if they look narrow. AB 1076 amended Section 16600 to say the rule should be read broadly in the employment context, and it added Section 16600.1 to make covered job-side non-compete language unlawful unless an exception applies.

SB 699 added Section 16600.5, which makes contracts void under the chapter unenforceable regardless of where and when they were signed and creates remedies for attempts to enforce covered void restrictions. That 2024 context matters if your search query is "are non-competes enforceable in California" or "is my non-compete enforceable in California." California's starting point is still the Section 16600 void rule.

That opening phrase also matters for buyers: "except as provided in this chapter." Section 16600 is the default rule. Section 16601 is one of the chapter's express exceptions.

In a normal California non-compete analysis, the default answer is usually hostile to enforcement. A covenant that simply blocks someone from working in a field or joining a competitor is a problem. California courts treat the state's policy against restraints of trade seriously, and 2024 legislation made invalid non-competes harder to include or enforce.

But an SMB acquisition is not a standard workforce mobility scenario. The buyer is paying for more than inventory, equipment, lease rights, and contracts. The buyer is also paying for customer relationships, reputation, referral patterns, trade name value, recurring accounts, and the seller's promise that those assets will not be immediately hollowed out after close.

That is where Business and Professions Code 16601 becomes the center of the analysis.

Section 16601: The Sale-of-Business Exception

Section 16601 allows a seller to agree with the buyer not to carry on a similar business within a specified geographic area where the sold business has been carried on, so long as the buyer continues a like business there.

The statute reaches several common acquisition structures:

• A person sells the goodwill of a business.
• An owner sells or disposes of all ownership interest in a business entity.
• A business entity sells all or substantially all operating assets together with goodwill.
• A business entity sells all or substantially all operating assets of a division or subsidiary together with that division's or subsidiary's goodwill.
• A business entity sells all ownership interest in a subsidiary.

That is why "business and professions code 16601" belongs in an APA diligence checklist for a California acquisition. The exception is not casual. It is tied to the deal's transfer of business value.

What goodwill means in this context

Goodwill is the part of the purchase price connected to expected patronage and business relationships. It is not just a nice reputation in the abstract. It is the going-concern value that makes the buyer believe customers, referral sources, suppliers, local reputation, and recurring revenue can continue after closing.

California Court of Appeal decisions have treated goodwill as the reason this carve-out exists. In Monogram Industries, Inc. v. Sar Industries, Inc. (1976) 64 Cal.App.3d 692, the court enforced a covenant connected to a business sale because the seller had transferred the value of the acquired business and then competed against it. Hill Medical Corp. v. Wycoff (2001) 86 Cal.App.4th 895 explains the policy in practical terms: when goodwill is sold, the seller should not be able to diminish the value of what the buyer just purchased.

For an ETA buyer, that means the APA should not treat the non-compete as a standalone punishment. It should connect the restriction to the goodwill being acquired.

What operating assets means

Section 16601 also covers a sale of all or substantially all operating assets together with goodwill. In an asset purchase, this is important. The buyer may not be buying stock or membership interests. The buyer may be buying the assets that allow the business to operate: customer contracts, equipment, trade names, domain names, phone numbers, books and records, inventory, licenses where transferable, vendor relationships, lease rights, and other operating inputs.

The statutory phrase "together with goodwill" is not decorative. If the APA says only that equipment and contracts are being assigned, but does not clearly transfer goodwill, the seller covenant gets weaker. A California seller non-compete is more defensible when the APA expressly says the buyer is purchasing goodwill and the covenant protects that purchased goodwill.

Why the carve-out exists

The carve-out exists because the buyer's bargain would be incomplete without it. A seller could otherwise take the closing payment, open a similar operation nearby, call the same customers, use the same referral routes, and drain the exact value the buyer paid to acquire.

Section 16601 balances that concern against California's general anti-restraint policy. It does not allow any restriction a buyer wants. It allows a restriction that is tied to the sold business, the geography where that business operated, and the buyer's continued operation of a like business.

The Enforceability Test for a California APA Non-Compete

A non-compete in APA California drafting should be tested across four practical dimensions: goodwill, geography, duration, and scope.

Goodwill must accompany the sale

The seller covenant should sit inside the acquisition story. The APA should say the buyer is purchasing goodwill, and the restrictive covenant should say it is designed to protect that goodwill.

This is especially important in asset deals where the seller may argue that only discrete assets changed hands. If the seller is selling customer relationships, the brand, the going concern, and the operating platform, the APA should say so. If it does not, the buyer leaves the non-compete more exposed.

Partial sales require extra care. In Samuelian v. Life Generations Healthcare, LLC, a published California Court of Appeal opinion from August 20, 2024, the court addressed a restraint following a partial sale of business interests and concluded that a reasonableness standard could apply rather than automatic invalidation. For ETA work, that means rollover equity, partial recapitalizations, and ongoing owner rights should be reviewed with counsel before assuming the same answer as a clean full sale.

Blue Mountain Enterprises, LLC v. Owen (2022) 74 Cal.App.5th 537 also shows that courts may read a package of sale and joint-venture documents together when deciding whether Section 16601 applies.

Geography should match the target's actual market

Section 16601 is geographically specific. The seller may agree not to carry on a similar business within the specified area where the sold business has been carried on, while the buyer carries on a like business there.

For a local California service business, that may mean a city, county, radius, or named territory supported by customer concentration. For a statewide customer base, a broader California restriction may be easier to justify. Alliant Ins. Services, Inc. v. Gaddy (2008) 159 Cal.App.4th 1292 upheld a statewide restriction where the acquired brokerage did business across California. Monogram likewise shows that broader territories can work when the sold business truly carried on business there.

The drafting point is simple: do not copy a national form and hope. Tie the territory to the target's actual customer footprint, revenue map, licensing territory, and referral area.

Duration is usually 3-5 years

Section 16601 does not provide a hard duration limit. That does not mean duration is irrelevant. In practice, 3-5 years is the zone buyers most often try to defend because it gives the buyer time to absorb goodwill, retain customers, transition the seller's relationships, and establish its own control of the business.

The stronger the seller's personal relationship to revenue, the more important the covenant becomes. A founder-led HVAC contractor, specialty medical practice, niche B2B service firm, or referral-heavy local business may need a meaningful period to transfer relationship trust. But a longer period should be tied to deal facts, not habit.

Scope must match the business sold

The restricted business should be the same or similar business that was sold. This is where many buyer forms overreach.

Strategix, Ltd. v. Infocrossing West, Inc. (2006) 142 Cal.App.4th 1068 is the key drafting warning. The court rejected covenants that protected the buyer's broader customer and personnel base rather than the sold business. The lesson for an APA is that Section 16601 protects the goodwill purchased from the seller. It does not give the buyer a blanket shield for every other business line the buyer owns.

APA Drafting Language to Request

Use these as issue-spotting requests for counsel. Final wording should be tailored to the deal structure, purchase price allocation, seller role, and California facts.

An ETA buyer's diligence layer should ask for these clause components:

1. Express goodwill transfer. The APA should say the purchased assets include the goodwill of the business, or that the equity sale includes the seller's ownership interest and associated goodwill.

2. Purpose clause. The covenant should state that it protects the buyer's purchased goodwill, customer relationships, confidential information, and going-concern value.

3. Restricted business definition. Define the restricted business by reference to the target's actual services, products, customer types, and territory as of closing. Avoid a generic "any business competitive with buyer" definition.

4. Restricted parties. Bind the seller, seller-controlled entities, and any principals receiving sale proceeds or transferring goodwill. Do not accidentally miss the entity or owner who could restart operations.

5. Restricted territory. Use a territory supported by the target's revenue, contracts, customer base, franchise area, service routes, or operating footprint.

6. Restricted period. Start the clock at closing, not at an ambiguous later event. If a post-close transition role exists, counsel should decide whether the covenant runs from closing, transition end, or both through separate obligations.

7. Direct and indirect conduct. Cover direct competition, ownership, management, consulting, financing, referral steering, and assisting another person to compete, while preserving negotiated passive-investment and unrelated-business carve-outs.

8. Customer and personnel non-solicit pairing. Pair the non-compete with carefully scoped non-solicit language tied to the sold business's customers, referral sources, vendors, and key team members. Keep it tied to the acquired goodwill.

9. Equitable relief and severability. Include injunctive-relief language and a severability clause, but do not rely on severability to rescue an overbroad covenant.

The best version reads like a deal-protection clause, not a generic restraint.

What Sellers Will Push Back On

Seller pushback is not always bad faith. Many sellers understand that California disfavors restraints and will resist language that feels broader than the business they sold.

Expect objections to:

• Territory. Sellers may accept counties where the target has customers, but resist statewide or national language if the revenue history is local.
• Business scope. Sellers may agree not to operate the acquired business line, but resist restrictions covering adjacent services, unrelated ventures, real estate holding companies, or passive investments.
• Duration. Sellers may accept 3 years more readily than 5 years. Anything longer needs stronger factual support.
• Affiliate reach. Sellers may object if the covenant binds spouses, relatives, trusts, portfolio entities, or passive ownership interests too broadly.
• Future buyer lines. Sellers will push back if the covenant protects businesses the buyer owns but did not acquire from the seller.
• Transition-role triggers. Sellers may resist a covenant that restarts after any consulting or advisory relationship ends.

That pushback helps the buyer sharpen the clause. If the buyer can explain why the restriction protects purchased goodwill, the clause usually gets stronger. If the only explanation is "our form says this," the clause is probably too broad.

Common Drafting Traps in California APAs

Overbroad scope

Do not define the restricted business as every service the buyer or its affiliates provide. Define it around the target business. If the buyer owns three unrelated portfolio companies, a California APA non-compete should not become a non-compete for all three.

Missing indirect-competition carve-outs

The clause should address indirect competition clearly. A seller should not be able to route business through a controlled entity, finance a competing startup, or advise a new competitor while claiming not to compete personally.

At the same time, buyers usually need carve-outs for passive investments, unrelated holdings, family trusts, pre-existing ventures, and activities outside the restricted business. A covenant with no carve-outs can look less reasonable than one that targets the real threat.

Ambiguous duration triggers

"For five years after termination" creates questions if the seller has a consulting, advisory, earnout, or transition services role. If the covenant is protecting closing-date goodwill, the buyer should think carefully before making the clock depend on a later relationship.

Fillpoint, LLC v. Maas (2012) 208 Cal.App.4th 1170 is a warning here. The court treated the acquisition documents together and distinguished a closing-date sale covenant from a later post-service restriction that overreached. The buyer should not assume that a later-triggered covenant is safer just because the seller once sold equity.

Missing non-solicit pairing

A non-compete without customer, referral-source, vendor, and key-personnel non-solicit language may leave a practical gap. The seller might avoid operating a competing entity while still steering relationships away from the buyer.

But the non-solicit must be scoped to the sold business's goodwill. Strategix warns against drafting a non-solicit that protects the buyer's entire enterprise rather than the acquired business.

Weak purchase agreement recitals

If the APA never says goodwill is part of what the buyer is buying, the non-compete has to work harder. Recitals are not magic, but they help frame the covenant as part of the sale consideration.

Ignoring neighboring statutory carve-outs

Section 16601 is not the only carve-out in the chapter. Section 16602 addresses partnership dissolution and dissociation. Section 16602.5 addresses certain LLC exits. If the target structure is a partnership or LLC member exit, counsel should check the specific statutory path.

2024 Context: SB 699, AB 1076, and the Sale Carve-Out

The search phrase "california non-compete 2024 changes" usually points to SB 699 and AB 1076.

SB 699 added Business and Professions Code Section 16600.5, which says contracts void under the chapter are unenforceable regardless of where and when signed, and creates remedies for attempts to use void restrictions in covered hiring-side contexts.

AB 1076 amended Section 16600 and added Section 16600.1, reinforcing broad treatment of invalid non-compete clauses and adding notice obligations for covered job-side contracts.

Those changes are real, but they do not delete Section 16601. The sale-of-business exception survives because Section 16600 still begins with an exception for other provisions in the same chapter, and Section 16601 remains one of those provisions. A valid sale-of-business covenant is not the same thing as a void job-side covenant.

The takeaway for ETA buyers: do not ignore California's 2024 changes, but do not let them scare you away from a properly drafted seller covenant. The work is in the facts and the drafting.

Action Checklist Before Close

Before signing a California APA, review the non-compete section against this list:

• Does the APA expressly transfer goodwill?
• Does the purchase price allocation or deal narrative support that goodwill transfer?
• Is the covenant signed by the right seller parties and seller-controlled entities?
• Is the restricted business limited to the target's actual business line?
• Is the territory tied to where the target actually carried on business?
• Is the duration in the 3-5 year zone, or does a longer term have clear deal support?
• Are direct and indirect competition both addressed?
• Are passive investment, unrelated-business, and pre-existing-activity carve-outs included where needed?
• Is the customer and personnel non-solicit language limited to the acquired goodwill?
• Does the covenant start at closing, or does a later trigger create avoidable ambiguity?
• Is there a separate analysis for partial rollover, partnership exit, LLC member exit, or transition-services structure?
• Has your M&A attorney reviewed the actual language, not just the business summary?
