Bylaws are the internal rulebook for a California corporation. An operating agreement is the equivalent for a California LLC. You never choose between them: your entity type decides. If you formed a corporation, you need bylaws. If you formed an LLC, you need an operating agreement. Neither one is filed with the state, and both are your job to write, keep and follow.
This guide explains how the two documents differ, what California law says about each, what goes wrong when owners skip them, and how to get the right one in place.
TL;DR
- Bylaws belong to corporations (directors, officers, shareholders). Operating agreements belong to LLCs (members and managers).
- California does not file, review or register either document. They are private, and you keep them with your records.
- A corporation can technically exist without bylaws in some cases, but in practice you need them. An LLC is governed by an operating agreement whether or not you wrote one down, and the default rules rarely match what owners intended.
- Ignoring your own governance documents can weaken your liability protection. Banks and investors will also ask to see them.
- Pick the document that matches your entity, then keep it current as your business changes.

The core difference in one table
| Corporate bylaws | LLC operating agreement | |
|---|---|---|
| Applies to | Corporations (C corp or S corp) | Limited liability companies |
| Who it governs | Shareholders, board of directors, officers | Members and managers |
| Style | Formal, structured, fairly rigid | Flexible, closer to a contract between owners |
| Typical topics | Board size, meetings, quorum, officer duties, voting | Ownership percentages, profit splits, management, buyouts, transfers |
| Filed with the state | No | No |
| Form of document | Written, kept at the principal office | Can be oral or implied by law, but should be written |
| Companion paperwork | Annual minutes, board and shareholder resolutions | Written consents, records of major decisions |
The functional difference is the one that matters. Bylaws set up a corporate machine with fixed roles. An operating agreement lets owners design their own deal: who puts in what, who decides what, and what happens when someone leaves.
What bylaws do for a California corporation
A California corporation has three layers: shareholders own it, a board of directors oversees it, and officers run it day to day. Bylaws explain how those layers work together. They typically cover:
- The number of directors and how they are elected or removed
- When and how the board and shareholders meet, and what counts as a quorum
- Officer titles and duties (president, secretary, chief financial officer)
- How shares are issued and transferred
- How the bylaws themselves can be amended
We go deeper on typical clauses in our practical guide to bylaws provisions, and on meeting rules in our California directors' quorum checklist.
Are bylaws legally required in California?
Mostly no, with one important catch. California Corporations Code § 212 says the bylaws must set out the number of directors unless the articles of incorporation already do. So if your articles are silent on board size, you need bylaws. A National Law Review commentary on California law makes the same point: no general requirement to have bylaws exists, though virtually every corporation has them.
Once you have bylaws, the law expects you to keep them somewhere findable. Corporations Code § 213 requires every corporation to keep the original or a copy of its bylaws, as amended, at its principal office in California.
So "not required" is a technicality. Without bylaws, your board has no written framework for meetings, officer appointments or voting. Banks, investors and insurers will expect them. If you are forming a corporation, adopt them. Our walkthrough on how to adopt corporate bylaws for a California corporation covers the steps, and our overview of California bylaws requirements covers the rules in more detail.
What an operating agreement does for a California LLC
An LLC has no board or shareholders by default. It has members (the owners) and sometimes managers. The operating agreement says how profits are split, who can sign contracts, how votes work, what happens when a member wants out, and what happens if one dies or divorces.
The California Secretary of State's entity types page notes that an LLC may be managed by one or more managers or by one or more members. Your operating agreement is where you pick and describe that structure.
Is an operating agreement required in California?
The answer has two layers, and many competing articles blur them.
- The LLC has one by law. Under the California Revised Uniform Limited Liability Company Act, the operating agreement is what governs relations among members and the company. The Secretary of State FAQ confirms it is not filed with the state and is kept by the business.
- It does not have to be written. The definition in Corporations Code § 17701.02 covers agreements that are oral, implied from conduct, or in a record. Some terms, such as changes to fiduciary duties, must be in a written operating agreement to be enforceable.
That is why "California does not require an operating agreement" and "California requires an operating agreement" both show up online. The accurate version: every LLC operates under one, and if you do not write your own, the statutory defaults fill the gaps.
Those defaults can surprise you. A two-person LLC where one partner put in $80,000 and the other put in sweat equity may find the law treats them very differently from what they shook hands on. Our guide on how to draft an operating agreement for a California LLC walks through the clauses.
Side by side: where the two documents really diverge
Flexibility
Bylaws sit inside a statutory framework for corporations. Directors, officers and shareholder votes follow set patterns, and your bylaws mostly fill in details. An operating agreement starts closer to a blank page. You can divide profits unevenly, give one member veto rights, or set up a manager-run LLC where passive investors have no say.
Formality and recordkeeping
Corporations are expected to hold meetings and record decisions, typically through annual minutes and resolutions. LLCs have lighter formalities, but a good operating agreement still calls for written consents on big decisions such as admitting a new member, taking on debt or selling the business.
Who signs
Bylaws are usually adopted by the board and certified by the corporate secretary. An operating agreement is signed by the members, because it is a contract among them. Even in a single-member LLC, sign it. Our article on the single-member LLC in California explains why paperwork matters for those owners too.
Tax elections
Neither document decides your taxes, but both should match them. An LLC that elects S corporation treatment still keeps an operating agreement, and its terms must work with that election. See our guide to the California LLC S corp election for how the two fit together.
Which one do you need?
Use your entity type as the filter.
- You filed Articles of Incorporation: you need bylaws, plus a habit of recording annual minutes.
- You filed Articles of Organization for an LLC: you need an operating agreement, written and signed.
- You have not formed anything yet: decide on the entity first. The Secretary of State describes how entities are formed through bizfile Online. Our guide to forming a California LLC and our overview of business incorporation services for California entrepreneurs can help you compare.
A common mix-up: an LLC owner downloads a bylaws template because a bank or a friend mentioned "bylaws." Bylaws assume directors, officers and shareholders, concepts an LLC does not have by default. Using them leads to confusion about who actually has authority. The reverse also happens: a corporation uses a member-style agreement with no board structure, which leaves the board without the procedures California corporate law expects.
Why skipping the paperwork costs you
Personal liability
The main reason to take governance documents seriously is liability protection. If owners ignore the formalities their own entity is supposed to follow, a court may treat the company as a shell and reach their personal assets. This is the "piercing the corporate veil" problem. Written bylaws and operating agreements, followed in practice, are evidence that the business is truly separate from you.
The same separation matters when you borrow. Lenders look at how an entity is run, and it helps to understand how to reduce personal liability when borrowing for business before you sign a personal guarantee.
Proof of authority
Banks, investors and agencies regularly ask for a copy of these documents before they open accounts, release funds or approve a deal. The San Francisco Treasurer's unclaimed funds instructions for businesses show one example: a business claiming funds has to prove that the person acting is an officer or authorized signer. Your governance documents are the natural proof.
Internal disputes
When co-owners disagree about money, control or exit, the document is the referee. If it does not exist, or says nothing on the topic, you are arguing from memory under the statutory defaults. Oral and implied agreements are legally possible, but they are hard to prove.
What we see at Legalstepz
We work with California corporations and small business owners every day, and the pattern is consistent. Founders do not usually skip these documents out of carelessness. They skip them because the state never asks for them. When you file Articles of Incorporation or Articles of Organization, nobody checks whether you also wrote the rulebook, and the first person to ask is typically a bank officer or an investor, at a moment when you need speed.
Our view is simple. Pick the document that matches your entity, make it fit your real business instead of a generic template, and then keep it alive. For corporations, that means annual minutes that reflect what the board actually decided, and bylaws amended when your practice changes. For LLCs, it means updating the operating agreement when members, capital or management change, not only on day one.
The documents do not have to be expensive or intimidating. They do have to be yours, consistent with your articles, and signed.

Keeping your documents current
A bylaws or operating agreement drafted at formation goes stale. Review it when any of these happen:
- You add or remove an owner, director or officer.
- You issue new shares or admit a member with a capital contribution.
- You change your management structure.
- You elect S corporation status.
- You take investment or a significant loan.
For corporations, write the changes into your minutes. Our drafting guide for California corporation annual minutes shows what to record. For LLCs, attach amendments to the operating agreement and have members sign them.

FAQ
Are bylaws and operating agreements the same?
No. Bylaws govern corporations, with their directors, officers and shareholders. Operating agreements govern LLCs, with their members and managers. Both are private internal documents, but they fit different legal structures and are not interchangeable.
Do LLCs need bylaws?
No. An LLC has no board of directors or shareholders by default, so bylaws do not fit. An LLC uses an operating agreement instead. If an investor or bank asks for "bylaws" from an LLC, they almost always mean the operating agreement.
Does California require LLCs to have an operating agreement?
California law treats every LLC as having one, but it does not have to be written, as Corporations Code § 17701.02 defines it. Even so, a signed written agreement is the practical standard. It protects you from the statutory defaults and gives banks and partners something to review.
Are California corporations required to have bylaws?
Only when the articles of incorporation do not state the number of directors, under § 212. In practice nearly every corporation adopts them, and § 213 requires you to keep a copy at your principal office.
Do I file either document with the Secretary of State?
No. The Secretary of State FAQ makes clear these stay with the business. You keep them with your records and show them when someone has a legitimate need to see them.
