Starting a Business in San Diego: The Legal Setup Checklist

Entity choice, briefly

• LLC: flexible, simple governance, pass-through taxation, well suited to service businesses and real estate holdings.
• S corporation election: often used to manage self-employment tax once profit is meaningful and owner compensation is reasonable.
• C corporation, typically Delaware: the standard for companies raising priced venture rounds, though it must still register to do business in California.
• All California entities owe the state's annual minimum franchise tax and must file a Statement of Information on schedule — a missed filing is the most common cause of suspended status.

Local registrations San Diego founders miss

Businesses operating in the City of San Diego generally need a Business Tax Certificate, and the surrounding cities — Carlsbad, Chula Vista, Escondido, Poway, Oceanside — each run their own version with their own renewal cycle. Home-based businesses are usually included.

Add a fictitious business name statement filed with the County of San Diego if you operate under a name other than your legal entity name, a seller's permit from the CDTFA if you sell tangible goods, and any zoning or use approval if you take a commercial space. Regulated categories — food, alcohol, cannabis, contracting, health services — carry their own licensing on top.

The documents that decide ownership

• An operating agreement or bylaws with real provisions on voting, deadlock, transfers, and buyout — not the two-page template that came with the filing service.
• Founder equity documents with vesting and, for corporations, timely 83(b) elections.
• Assignment of intellectual property from every founder, employee, and contractor, including anything built before formation.
• A buy-sell provision covering death, disability, divorce, and departure.

Before the first hire

• Register with the EDD, obtain workers' compensation coverage, and post the required notices.
• Classify correctly: California's ABC test makes most contractors employees, and misclassification is the most expensive early-stage mistake.
• Use compliant offer letters, a wage-theft prevention notice, and an employee handbook that reflects California — not a template written for another state.
• Confirm exempt salaries clear California's two-times-minimum-wage threshold.

Customer and vendor paper

One well-drafted master services agreement or terms of sale, with clear scope, payment terms, limitation of liability, IP ownership, and a dispute clause naming San Diego County, prevents most of the collection and scope fights that fill the first three years.
