How to start a business in San Diego.
San Diego pairs a world-class biotech and research cluster around Torrey Pines and La Jolla with one of the largest military communities in the country, and wraps it all in a beach city that tourists visit year-round. Add a craft beer scene famous nationwide and a busy cross-border economy with Tijuana, and you get a diverse metro where service, science, and lifestyle businesses all find customers. The weather alone keeps half the local economy outdoors. This guide starts where it should: with the idea, then walks the honest steps to make it official.

San Diego, specifically.
San Diego moves at its own sunny pace, but do not mistake relaxed for unambitious: this city discovers medicines, builds for the Navy, and brews some of the best beer in America. It is a place where a wetsuit and a business plan can share the same trunk. Build something that fits the life people came here for and they will make it part of their routine.
Business districts and neighborhoods worth knowing: the Gaslamp Quarter, North Park, La Jolla, Old Town, Sorrento Valley, Barrio Logan.
The steps to make it official
- 1
Pick your business structure
Most first businesses in San Diego choose an LLC for the liability separation between the business and your personal life. Sole proprietorships are simpler but offer no separation; corporations fit businesses raising investment.
- 2
Check that your business name is free
Search the California Secretary of State's business registry to confirm nobody in California already holds the name, and check the matching web domain at the same time.
- 3
File your formation documents with the California Secretary of State
An LLC or corporation forms at the state level, not the city level. File directly with the California Secretary of State and pay only the state's filing fee. You will need a registered agent with a physical address in California; if you live here, you can usually be your own.
- 4
Get your EIN free from the IRS
The Employer Identification Number is the business's tax ID. The IRS issues it directly at irs.gov in about five minutes, at no charge. Never pay anyone for an EIN alone.
- 5
Register with the city and check licenses
Most businesses operating in San Diego need a city business tax registration and possibly zoning or health permits. Check the city's finance office and your local city hall for what applies to your specific business and location.
- 6
Open the business bank account and connect payments
Keep business money separate from day one: it protects the legal separation your LLC exists for and keeps taxes clean. Bring your EIN and formation documents to the bank.
Registering it is one step. Building it is the journey.
