In-House vs. Outsourced Facility Services: Total Cost Comparison

One of the most consequential decisions a facility director makes is whether to self-perform facility services with in-house staff or outsource them to specialized contractors. Both models have genuine advantages — and both have real costs that are frequently underestimated when comparing them.

The mistake most organizations make is comparing the fully-loaded cost of outsourcing against the direct salary of an in-house employee. This produces a misleading result. A fair comparison requires calculating the true total cost of each model.

The True Cost of In-House Employees

Direct salary is typically 60–70% of the actual cost of an in-house maintenance employee. The remaining 30–40% is overhead that's real, but often invisible in budget discussions:

• Payroll taxes: Employer portion of FICA (7.65% of gross wages), federal and state unemployment taxes — adds approximately 10–12% to base wage
• Health insurance: Employer contribution averages $7,000–$15,000/year per employee in 2026
• Paid time off: 2 weeks vacation + 5 sick days + 10 holidays = 25 days @ ~9% of annual salary that produces no work
• Workers' compensation insurance: 3–15% of gross wages depending on trade classification (maintenance/janitorial is typically 5–8%)
• Retirement benefits: Employer 401k match averages 3–6% of salary
• Training and certifications: EPA 608, OSHA 10/30, trade certifications — $500–$2,000/year plus lost productivity time
• Supervision overhead: Facility manager time spent on HR issues, scheduling, performance management — often 15–25% of a manager's time for a team of 3–5
• Equipment and tools: Power tools, floor machines, HVAC gauges, vehicles — capital cost amortized over service life
• Uniforms, PPE, and supplies
• Recruitment and turnover costs: Average cost to recruit and onboard a maintenance technician is $3,000–$8,000

Loaded labor cost multiplier: 1.35x–1.45x base salary. A maintenance technician earning $55,000/year in salary costs $74,000–$80,000 in total loaded cost.

Sample Total Cost Comparison: Janitorial Services

Cost Element	In-House (Annual)	Outsourced (Annual)
Direct wages (2 FTE)	$78,000	—
Payroll taxes & WC insurance	$14,000	—
Health insurance (employer)	$22,000	—
Equipment & supplies	$8,000	—
Management overhead (est.)	$12,000	—
Contract price	—	$96,000
Total Annual Cost	$134,000	$96,000

In this example, in-house cleaning appears cheaper at first glance ($78K wages vs. $96K contract) — but when all costs are included, outsourcing saves $38,000/year.

Where In-House Wins

The economics don't always favor outsourcing. In-house staffing offers genuine advantages in specific scenarios:

• Institutional knowledge: Long-tenured in-house technicians know the building's quirks, history, and systems in ways that contracted staff typically don't
• Rapid response: An on-site engineer can respond to a building issue in minutes vs. a contracted service call that may take hours
• Flexibility: In-house staff can handle a wider variety of tasks without scope-of-work debates
• Culture and accountability: In-house employees have stronger organizational loyalty and accountability to building occupants
• Large facilities: For buildings over 500,000 sq ft with complex systems, a hybrid model with in-house engineers supplemented by specialty contractors often delivers the best outcome

Where Outsourcing Wins

• Specialty services: HVAC, fire protection, elevator — these require specialized tools, certifications, and ongoing training that are prohibitively expensive to maintain in-house except for the largest portfolios
• Labor flexibility: Seasonal fluctuations (landscaping, snow removal) are efficiently absorbed by contractors without carrying full-time year-round headcount
• Compliance burden transfer: Licensed contractors carry the compliance liability for their trade — EPA certifications, pesticide licenses, elevator licenses
• Smaller properties: Properties under 100,000 sq ft rarely justify full-time maintenance staff for all service categories
• Scalable growth: Organizations managing growing portfolios can expand service capacity without HR overhead

The Hybrid Model

Most large commercial facilities operate a hybrid model: in-house facility engineers or day porters handle routine building operations and rapid-response needs, while specialty trade services (HVAC, electrical, fire protection, plumbing, janitorial) are outsourced to licensed contractors.

This model captures the institutional knowledge and response speed benefits of in-house staffing while leveraging the specialized expertise and compliance infrastructure of contractors for work that requires it.

Decision Framework

Use these questions to guide the in-house vs. outsource decision for each service category:

1. Does the work require a state license or specialized certification that would be costly to obtain and maintain in-house?
2. Is the workload consistent enough to justify dedicated headcount, or is it seasonal or variable?
3. Is the market depth of qualified contractors sufficient for competitive pricing and quality?
4. What is the true loaded cost of an in-house FTE vs. the all-in contract cost?
5. How critical is rapid on-site response — and can a contractor deliver acceptable SLAs?
6. Does the complexity and institutional knowledge required favor long-tenured in-house staff?
