Columbus is the only major Ohio metro adding office inventory: Short North, the Arena District, and New Albany’s corporate campus belt have absorbed relocated Midwest headquarters. Ohio State University generates institutional cleaning volume that few metros its size can match. SEIU Local 1 covers larger downtown Class A towers; suburban Westerville and Dublin run non-union at market rates. Ohio’s Bureau of Workers’ Compensation is a monopoly state fund that simplifies insurance administration but removes the ability to shop comp rates.

Loaded Labor Cost in the Columbus Market

BLS OEWS May 2024 (SOC 37-2011) puts the Columbus MSA mean in the $15.50–$16.50/hr range. Ohio’s minimum wage reached $11.00/hr in January 2026 per the Ohio Department of Commerce. Downtown Columbus and OSU-adjacent accounts run at BLS mean; suburban and light-industrial accounts often settle nearer $13–$14. See the wages breakdown for the Columbus MSA.

Burden math on a $16/hr Columbus base: FICA 7.65% = $1.22; FUTA/SUTA ~2.5% = $0.40; Ohio BWC workers’ comp for janitorial approximately $2.00–$2.60 per $100 payroll per the Ohio Bureau of Workers’ Compensation; health insurance ~$3.25/hr; vacation ~4–5%. Total burden: 27–32%, loaded rate near $20–$22/hr.

Sample Scope of Work: Class B Office Building

Hypothetical 42,000 sq ft Class B building in the Short North or Arena District. Columbus winters are moderate but consistent; ice-melt salt season runs November through February.

Columbus Going Rates: Class B Office and Day Porter

Arena District and Short North Class B commands $0.09–$0.13/sq ft/month for 5x/week. New Albany and Easton corridor: $0.08–$0.11. Westerville and Dublin suburban: $0.07–$0.10. Day-porter bill rate: $21/hr x 2.3 = approximately $48–$50/hr; 4-hr/day porter near $1,000/month. Model accounts with the production rate calculator. Medical office on the OSU Health corridor adds +20–30%; post-construction work +40–55%.

Ohio Licensing and Insurance Requirements

Ohio does not require a statewide janitorial contractor license. Columbus requires a general business registration through Columbus Business Licenses and Permits. Ohio workers’ comp is a monopoly state fund administered by the Ohio Bureau of Workers’ Compensation; operators cannot use private carriers for core coverage. New businesses pay group rates until they accumulate sufficient payroll history for individual experience rating, typically 36 months. GL minimums: $1M/$2M for Class B commercial; $2M/$5M for Class A and healthcare. Janitorial bonds of $10,000–$25,000 standard.

Union Presence and Prevailing Wage Triggers

SEIU Local 1 covers most downtown Columbus Class A and major healthcare campus accounts. Their scale runs above the BLS MSA mean by $2–$4/hr with health and pension contributions. Suburban accounts are largely non-union and price-competitive. Ohio’s Prevailing Wage Law applies to public construction and some public service contracts; check the Ohio Department of Commerce for current rates. Federal contracts at Columbus Defense Supply Center and federal office buildings require SCA compliance; wage determinations at SAM.gov.

What Columbus Buyers Expect in a Bid Response

1. Monthly base service: labor hours by position at loaded rate.
2. Winter services add-on: mat exchange and salt-removal protocol quoted separately.
3. Supplies schedule: consumable unit prices.
4. Equipment depreciation: 36-month amortization.
5. Insurance allocation: GL, BWC comp, and bond pro-rated to contract value.
6. Overhead and margin: 12–18% overhead; 8–14% profit.

Local quirk: Ohio BWC participation is mandatory; private workers’ comp policies fail vendor qualification on state agency, OSU, and hospital RFPs requiring BWC clearance documentation.

Bid Walk Checklist: Columbus MSA

1. Confirm Ohio BWC clearance status before bid submission; state and university buyers check this at vendor qualification.
2. Walk all entry points; identify mat storage capacity for winter exchange program.
3. Check lobby floor surface: Arena District buildings vary between polished concrete, tile, and carpet.
4. Ask about LEED or sustainability certification; OSU-adjacent properties often require Green Seal products.
5. Note any medical or dental tenant floors; they require separate scope and pricing.

The Ohio BWC Monopoly: Tradeoffs for Out-of-State BSCs

Ohio BWC is a state-fund monopoly: no private carrier can substitute. Out-of-state operators accustomed to shopping comp rates lose that lever entirely in Ohio. New entrants pay group rates for up to three years before individual experience rating applies; comp expense is fixed regardless of safety performance during that period. Factor the group rate into every Columbus bid. The account profitability auditor can model the group-versus-experience-rated comp impact per account.
