Staffing agencies in San Diego: the county market, California's rules and what a schedule costs

This report is for San Diego County employers choosing a staffing agency, people looking for work through one, and B2B sellers whose customers are staffing firms in the region.

San Diego's staffing market in Census data

The figures cover the San Diego-Chula Vista-Carlsbad, CA Metro Area (CBSA 41740), which is San Diego County, and two industry codes: NAICS 56131 (Employment Placement Agencies and Executive Search Services) and NAICS 56132 (Temporary Help Services). Source: US Census Bureau, County Business Patterns 2023.

The Census Bureau's metro file splits that into three businesses:

The executive search employee count carries the Census Bureau's high-noise flag (the noise it adds for confidentiality changed it by 5% or more), so it's left out. Temp help holds 87% of the employees because temp agencies employ the people they place: the Census definition says those workers "are employees of the temporary help services establishment." A biotech lab assistant in Sorrento Valley or a picker in Otay Mesa can be on an agency's payroll, which is why 299 temp locations average 59 employees while placement agencies average 18.

The Census Bureau doesn't publish the combined cells above 249 employees, so the 20 is the total less the published classes. The industry rows fill it in: 18 temp help locations have 250 to 499 employees and 2 have 500 or more. In broader bands, 356 establishments have 1 to 19 employees, 112 have 20 to 99 and 59 have 100 or more.

County Business Patterns counts establishments with paid employees, not companies: a national firm with branches in Kearny Mesa, Carlsbad and Chula Vista counts three times, and self-employed recruiters aren't counted. Professional employer organizations (NAICS 56133, 36 more locations here) are excluded, and the headcount is the week of March 12, 2023.

No exchange-listed staffing company is headquartered in the county. EDGAR files one Escondido company, Dalrada, under help supply services, but its 10-K for the year ended 30 June 2025 reports $20.3 million in revenue from health, climate technology, precision manufacturing and technology segments, and it registers no shares on an exchange.

California rules that change the deal

Because of 2810.3, ask for the agency's workers' compensation certificate and its wage-and-hour record, not just its rates: if it shorts its workers, they can come to you.

Worked example: where the site is and how the shifts run

Illustrative example. The company, markup and billing terms are invented; the wage rates are the published 2027 minimums.

Mesa Verde Packing (mesaverdepack.example) wants 20 temps at minimum wage from January 2027 and is choosing between a building inside the City of San Diego and one outside the city limits where the state rate applies. The agency marks up pay by 40% and bills overtime hours at 1.5 times the bill rate.

Then the schedule. At the city site, a worker on five 8-hour days costs 40 × $25.69 = $1,027.60 a week. Four 10-hour days add two overtime hours each day: 32 hours at $25.69 plus 8 hours at $38.54 makes $1,130.36, so $102.76 more per worker per week, about $2,055 a week for the crew. The 4x10 may still be worth it for retention or equipment use, but price it with the overtime in.

Choosing an agency in San Diego

1. Match the agency to the work: light industrial and logistics temps, life sciences and lab contractors, IT contract staffing, healthcare staffing, temp-to-hire, direct hire or executive search. A PEO is for payroll and HR on staff you already employ.
2. Confirm the entity on the California Secretary of State's bizfile search and get certificates of workers' compensation and general liability insurance.
3. Ask for an itemized quote with pay rate, markup, overtime and double-time billing, sick leave handling and conversion fees.
4. Check which minimum wage applies at each work address.
5. Read reviews and call references: ClearlyRated lists San Diego agencies with client and talent ratings.

If you're looking for work, California's weekly pay rule means a temp assignment should pay you at least every week. Register with two or three agencies that place people in your field and ask each for the pay rate and the work address before you accept.

Selling to San Diego staffing agencies

California compliance is the strongest angle here. Weekly and daily pay, daily overtime, local minimum wages and shared-liability clients make payroll, timekeeping and wage-and-hour auditing tools an easy conversation with temp branches. The 228 placement and search offices buy candidate data and recruiting software. Start from the California Staffing Professionals association and the ASA directory, and read job postings to split light industrial from life sciences and IT recruiters. Research is the slow part at volume; Bebop finds agencies that match a description and explains why each fits. For outreach method, see how to write a cold email.

Subject: Daily pay and the 2027 rate change

Hi [first name],

I saw [agency] is placing [role] at sites across San Diego County. With the city's minimum wage moving to $18.35 in January and daily pay due for dispatched workers, rate changes tend to land on payroll at once.

We [what you do, e.g. flag the right minimum wage by work address] so every timesheet is paid at the right rate.

Would it be useful to run last month's timesheets through it?
