California: Corporate Bylaws Adoption and Amendment Requirements

Requirements one by one

California makes the board-number term mandatory somewhere

Corporations Code §§ 210-213 do not use a blanket command that every ordinary
stock corporation shall adopt bylaws. Section 211 instead says bylaws “may be
adopted,” while § 212(a) requires the authorized number of directors—or a
permitted minimum and maximum—to appear in the bylaws unless that provision is
in the articles.

That distinction matters. A corporation whose articles already state the
director number does not get a second statutory board-number duty in bylaws,
but any bylaws it adopts remain subject to the content, amendment, and records
rules in the same sections.

Adoption and amendment use different approval denominators

Under §§ 151-153, “approval of the board” and “approval of the outstanding
shares” are defined terms. Section 211 allows either route for ordinary bylaw
adoption, amendment, or repeal. Outstanding-share approval means an affirmative
vote of a majority of all outstanding shares entitled to vote, plus any
required class or series approval—not merely a majority of shares represented
at a meeting.

If the articles did not name initial directors, § 210 lets the incorporators
perfect the organization, including adopting or amending bylaws, until
directors are elected. Under §§ 307 and 311, ordinary board authority and
committee limits remain distinct; § 603 supplies the shareholder written-
consent route. The required consent record or vote still follows the actor and
approval standard that applies.

Board-number amendments have a special shareholder gate

Section 212 ordinarily permits a fixed board or a minimum-to-maximum range, but
the maximum cannot exceed two times the minimum minus one. It also carries
limited one- or two-director routes before shares issue and while the
corporation has only one or two shareholders.

After shares have been issued, a bylaw that changes the fixed number, changes
the minimum or maximum, or switches between a fixed and variable board requires
approval of the outstanding shares. A board that otherwise has bylaw-amendment
power cannot use that general authority to bypass this specific gate.

Current bylaws must remain available to shareholders

Section 213 requires the original or a current amended copy at the corporation's
California principal office or principal California business office, open to
shareholder inspection at reasonable times during office hours. If the
corporation's principal office is outside California and it has no California
principal office, it must furnish a current copy when a shareholder requests
one in writing.

The statute does not make general Secretary of State filing, notarization, or a
particular certification signature an ordinary bylaw-validity step. Under
§ 1500, corporate books and minutes may be kept in written form or another
form capable of conversion into clearly legible tangible form.

What trips people up

A board committee cannot amend the bylaws. Even though § 151's board-approval
definition can include an authorized committee, § 311(d) expressly withholds
amendment, repeal, and adoption of bylaws from committee authority.

Board power is also not irrevocable. Section 211 permits the articles or bylaws
to restrict or eliminate the board's power to adopt, amend, or repeal some or
all bylaws, subject to the higher-vote rule in § 204(a)(5).

Common questions

Who can adopt California bylaws before the first directors are elected?

If the articles did not name initial directors, § 210 lets the incorporators
adopt or amend bylaws while they are completing organization. After directors
are in place, § 211 supplies the board and outstanding-share routes.

Is a meeting majority enough for shareholder adoption?

Not for the “approval of the outstanding shares” route in § 211. Section 152
defines that term as a majority of all outstanding shares entitled to vote,
with any required class or series approval.

Must California bylaws be filed publicly?

The ordinary bylaw sections do not prescribe a Secretary of State filing.
Section 213 instead treats the current bylaws as an internal corporate record
that must be available or furnished to shareholders under its location rule.
