Janitorial wages — Columbia, SC metropolitan area
Columbia’s janitorial market runs on three institutional anchors: South Carolina state government (the Capitol complex and dozens of agency headquarters), Fort Jackson – the largest Army basic combat training installation in the nation – and the University of South Carolina. Together these produce a commercial BSC market that is split between low-margin open-market accounts and government-rate work where SCA and state procurement rules apply. Operators who cannot execute in both tracks will leave money on the table in a market that rewards compliance capability.
BLS Wage Data: What Janitors Earn in Columbia
Per BLS OEWS Metropolitan Area tables (May 2024), the Columbia MSA places janitorial mean hourly wages (SOC 37-2011) in the $13–$15.50/hr range, within the Sunbelt band. The national mean of $17.43/hr is roughly 15–25% above Columbia’s median. The metro employs approximately 7,000–10,000 janitors across state government, Fort Jackson, healthcare (Prisma Health, Providence Health), USC, and commercial office.
| Percentile | Est. Hourly Wage | Context |
|---|---|---|
| 10th | $9.50–$11.00 | Marginal commercial and part-time |
| 25th | $11.50–$13.00 | Strip commercial and retail cleaning |
| 50th (median) | $13.00–$15.00 | Full-time commercial office and healthcare-adjacent |
| 75th | $16.00–$18.50 | Hospital EVS, state government campus, Fort Jackson |
| 90th | $19.00–$22.00 | Senior hospital and federal SCA at Fort Jackson |
Wage Drivers: What Shapes Columbia Labor Costs
BEA Regional Price Parities place Columbia near 88–92 nationally, per BEA Regional Price Parities. Low South Carolina housing and utility costs explain the nominal gap from the national mean. State government employment (DOR, DHEC, DOT, SCDNR) generates concentrated cleaning demand in the downtown Statehouse corridor. Fort Jackson produces large-volume training facility and barracks cleaning contracts at SCA rates. South Carolina unemployment tracked 3.0–4.0% through 2024 per BLS LAUS.
Loaded Labor Cost: What Employers Actually Pay
Burden breakdown at $14.00/hr: FICA 7.65% ($1.07) + SC SUTA ~2% ($0.28) + workers’ comp $1.60–$2.30/$100 per South Carolina Department of Insurance + GL ($0.30/hr) + health ($1.50–$2.75/hr) + PTO ($0.37/hr). $14.00 × 1.29 = $18.06 loaded; supervision adds $0.35–$0.55 = $18.41–$18.61 all-in.

State Minimum Wage and Local Premiums
South Carolina has no state minimum above the federal $7.25/hr, per South Carolina DLLR, Wage and Hour. No Columbia city or Richland County ordinance operates above the federal floor. The practical market floor for commercial janitorial sits near $11–$13/hr driven by market competition. Tipped wage exemptions do not apply to cleaning work.
Union Landscape and Collective Bargaining
South Carolina is a Right-to-Work state. Commercial BSC janitorial work in Columbia is virtually all non-union. Fort Jackson cleaning contracts are SCA-governed but not collectively bargained. USC and state agency custodial staff employed directly may have classified employee associations. See SEIU.org for organizing context.
Workers’ Compensation Rates for NAICS 561720
South Carolina workers’ comp rates for NAICS 561720 run approximately $1.60–$2.30 per $100 payroll. Coverage is mandatory for employers with four or more employees. Details at South Carolina Department of Insurance.
Prevailing Wage and Service Contract Act Implications
Fort Jackson is the largest SCA cleaning opportunity in the Columbia MSA. Wage determinations are at SAM.gov Wage Determinations; SCA janitor rates for the Columbia area typically run $15–$18/hr. State government contracts follow South Carolina procurement rules rather than SCA. See DOL Service Contract Act.
Total Compensation: Benefits, Turnover, and Hiring Cost
Per BLS Employer Costs for Employee Compensation, benefits represent 27–31% of total compensation. South Carolina has no state-mandated paid sick leave. Per ISSA benchmarks, janitorial turnover runs 75–200% annually. Replacing one Columbia janitor costs roughly $1,200–$2,600 per event at local wage levels.
State Procurement and SCA Are Parallel Compliance Tracks
A Columbia BSC pursuing both state agency contracts and Fort Jackson federal work operates under two separate compliance regimes simultaneously. South Carolina procurement contracts require compliance with SC wage and hour law, state audit rights, and specified service standards; Fort Jackson requires SCA certified payrolls, federal contracting officer oversight, and fringe benefit accounting. A BSC that conflates the two will be non-compliant on both. The operators who win the most Columbia government work maintain separate billing, payroll, and documentation tracks for state versus federal contracts as a standard operating procedure, not as a special project.
