The El Cajon business count, sector by sector

In the ZIP code that lie mostly inside El Cajon (92020), the Census counted 1,964 business establishments with employees in 2023. A sample of that count, and what each kind of business needs online:

  • Barber shops (9): prices, hours and photos of the shop and the work.
  • Plumbing, heating and air-conditioning contractors (58): the services you offer, the towns you cover and a form for service calls that lands in your email.
  • Auto repair shops (49): the services you do, the makes you work on, hours and a form to describe the problem.
  • Quick-service restaurants (62): the menu with prices, hours and the closest cross streets.
  • Dental offices (36): the team, the treatments in plain words and a form that sends appointment requests to your email.

San Diego County as a whole had 93,407 employer establishments in 2023 and another 299,736 nonemployer businesses, the one-person shops and independent contractors that often have no website at all. Compared with the U.S. as a whole, San Diego County leans toward professional service firms (16,216 establishments, 1.5 times the national share). For them, clients check credentials before they call, and the website should show practice areas, people and credentials, and a contact form that reaches the right person. Next on the list: real estate businesses, 6,696 of them, at 1.4 times the national share. El Cajon’s working residents are concentrated in education, health care and social assistance (22.6%) and retail trade (13.7%). None of them needs a complicated site; they need one that answers the customer’s first questions honestly.

Before you publish: California and federal rules

Some homework before launch:

  • The California Consumer Privacy Act, as amended by the California Privacy Rights Act (CCPA/CPRA) rarely reaches a local business: For-profit businesses doing business in California that meet any one of three tests: gross annual revenue over $25 million; buying, selling or sharing the personal information of 100,000 or more California residents or households; or deriving 50% or more of annual revenue from selling California residents’ personal information. A typical small business (a local service company with a brochure site or a small store) meets none of them and is outside the CCPA – but CalOPPA still requires a privacy policy (see outras_leis_site). California Civil Code, Title 1.81.5 (Civ. Code 1798.100 et seq.)
  • Under ADA Title III, a business open to the public should make its website usable by people with disabilities, according to the Justice Department’s guidance. ADA.gov guidance
  • California’s statewide sales and use tax rate is 7.25%, and most areas add district taxes of roughly 0.10% to 2.00% on top of it. California Department of Tax and Fee Administration (CDTFA)
  • Cities and counties issue the local business license or business tax certificate; the state’s CalGOLD tool lists the permits a given business needs at a given address. In El Cajon, that means asking San Diego County and the City of El Cajon. Official source
