Sole proprietorship: one owner, personally liable for all debts and lawsuits; no liability protection for personal assets.
General partnership: two or more owners; each partner personally liable for all partnership debts and other partners' negligence.
Limited partnership: general partners liable, limited partners liable only to investment amount if they remain passive.
LLC: members' liability limited to investment; requires Articles of Organization filing with Secretary of State; most popular CA plumbing structure.
S-Corp: shareholders have limited liability; passes through income to avoid double taxation; requires IRS qualification and ongoing compliance.
C-Corp: shareholders have limited liability; subject to double taxation (corporate and shareholder level); expensive to establish and maintain.
DBA registration: required if operating under any name other than legal name; registered with county clerk; provides zero liability protection; renew every 5 years.
CSLB license depends on structure: sole proprietor (individual name), GP/LP (partnership name), LLC (LLC name with members listed), corporation (corporate name with managing officer listed).
Any change in business structure or ownership requires CSLB notification; failure to update license creates regulatory violations.
Maintaining corporate formalities and separating business from personal finances required to preserve liability protection; commingling finances risks "piercing the veil."
