Manufacturing employs 20,985 people in Stanislaus County, much of it canneries, dairies, and packing plants that run heavy seasonal shifts and need break rooms, locker rooms, and plant offices kept up through peak season. Health care is the largest employing sector, with 5 hospitals and a growing number of clinics serving a county of 557,719. Retail ranks second, from regional shopping centers to the stores along McHenry Avenue. Transportation and warehousing rounds out the top five as distribution sites spread along the main valley freeway corridor.

What this means when you scope a building

  • Food-processing plants swing between off-season and peak. Ask for a contract with a seasonal step-up built in.
  • Health care employs 29,289 people in the county, and clinics need exam and waiting rooms on a separate checklist.
  • Valley dust settles fast. Put high dusting of vents, ledges, and fixtures on a monthly list.
  • With a median janitor wage of $18.89, trimming nightly visits in low-use offices holds cost down.
