When to Hire a General Contractor vs. Specialty Subcontractor

One of the most common questions property managers and project owners face is whether to hire a general contractor (GC) or go directly to specialty subcontractors. The right answer depends on the project scope, complexity, timeline, and your own management capacity.

This guide breaks down when each approach makes sense, the cost implications, and how to make the best decision for your project.

Understanding the Roles

What Does a General Contractor Do?

A general contractor manages the entire construction project, including:

• Project planning and scheduling
• Hiring and managing subcontractors
• Procuring materials
• Obtaining permits
• Quality control and inspections
• Safety management on-site
• Budget management
• Communication with the owner
• Change order management
• Project closeout and warranty

The GC is your single point of accountability. They take on the risk of coordination, scheduling, and quality.

What Does a Specialty Subcontractor Do?

A specialty subcontractor is a tradesperson or company that specializes in one specific area:

• Plumbers
• Electricians
• HVAC technicians
• Roofers
• Painters
• Flooring installers
• Drywall contractors
• Concrete contractors
• Landscapers

Subcontractors focus on their trade and typically don't manage other aspects of the project.

When to Hire a General Contractor

1. Complex, Multi-Trade Projects

Examples:

• Building renovations
• Tenant build-outs
• Multifamily property renovations
• Commercial facility upgrades
• Ground-up construction

Why a GC makes sense:

• Multiple trades need coordination
• Scheduling dependencies are complex
• Permitting and inspections required
• Single point of accountability
• Quality standards need management across trades

2. Projects Requiring Permits and Inspections

Any project that requires building permits typically benefits from a GC who:

• Knows local building codes
• Has relationships with permit offices
• Manages inspection scheduling
• Ensures code compliance
• Handles any required revisions

3. Projects with Tight Timelines

A GC can:

• Sequence trades for maximum efficiency
• Manage overlapping work schedules
• Handle delays and adjustments
• Keep the project on critical path

4. When You Lack Time or Expertise

If you don't have the time, knowledge, or desire to manage multiple subcontractors, a GC takes that burden off your shoulders.

5. High-Value or High-Risk Projects

For projects where mistakes are costly, the accountability a GC provides is worth the premium. The GC assumes risk that you would otherwise carry.

When to Hire Specialty Subcontractors Directly

1. Single-Trade Projects

Examples:

• Roof replacement (hire a roofer directly)
• HVAC unit replacement (hire an HVAC contractor)
• Electrical panel upgrade (hire an electrician)
• Plumbing repair (hire a plumber)
• Interior painting (hire a painting contractor)

When only one trade is involved, you don't need a GC to coordinate.

2. Small-Scope Projects

Examples:

• Replacing a water heater
• Fixing a leaky faucet
• Repairing drywall damage
• Replacing a section of flooring
• Installing a ceiling fan

For small jobs, a GC's overhead isn't justified.

3. Routine Maintenance and Repairs

Ongoing maintenance tasks are best handled by direct relationships with specialty contractors:

• Quarterly HVAC service
• Annual roof inspections
• Regular plumbing maintenance
• Preventive electrical inspections

4. When You Have Project Management Capability

If you have in-house maintenance staff or project management expertise, you can coordinate subcontractors directly and save the GC markup.

5. Emergency Repairs

When something breaks, you need the specific tradesperson immediately—not a GC who will then subcontract the work.

Cost Comparison

General Contractor Pricing

GCs typically charge for their services through:

• Markup on subcontractor costs: 10-25% on top of subcontractor pricing
• Markup on materials: 10-20% on materials they procure
• Project management fee: 5-15% of total project cost
• Overhead: 5-10% for office, insurance, administrative costs

Total GC overhead: Typically 15-30% above the cost of direct subcontractors.

Direct Subcontractor Pricing

When you hire subcontractors directly, you save the GC markup, but you take on:

• Coordination time and effort
• Scheduling responsibility
• Quality control across trades
• Permit management
• Risk of trade conflicts and scheduling gaps

The Real Cost Calculation

GC-Managed Project Example ($100,000 renovation):

• Subcontractor work: $70,000
• Materials: $15,000
• GC markup/overhead: $15,000
• Total: $100,000

Direct Subcontractor Management Example:

• Subcontractor work: $70,000
• Materials: $15,000
• Your management time (40 hours @ $50/hr): $2,000
• Scheduling inefficiency risk: $2,000-$5,000
• Quality issues/risk: $2,000-$5,000
• Total: $91,000-$97,000

The savings from going direct may be $3,000-$9,000, but you take on significant risk and time commitment.

Decision Framework

Questions to Ask Yourself

1. How many trades are involved?

   • 1 trade → Hire the subcontractor directly
   • 2-3 trades → Consider direct management if you have time
   • 4+ trades → Hire a GC

2. Is a permit required?

   • Yes → GC recommended for code compliance and inspection management
   • No → Direct subcontractor may work fine

3. What's the project value?

   • Under $5,000 → Direct subcontractor
   • $5,000-$25,000 → Depends on complexity
   • Over $25,000 → GC recommended for risk management

4. What's the timeline pressure?

   • Flexible → Direct management is feasible
   • Tight → GC can sequence efficiently

5. Do you have project management expertise?

   • Yes → Direct management saves money
   • No → GC provides that expertise

6. Is the project high-risk?

   • Low risk (routine work) → Direct is fine
   • High risk (structural, life safety) → GC accountability is valuable

Hybrid Approach: Construction Management

What Is Construction Management?

A construction manager (CM) acts as your agent—managing subcontractors, scheduling, and quality—without marking up subcontractor costs. You pay a management fee, and the subcontractors are contracted directly to you.

Benefits of CM Approach

• No markup on subcontractor costs
• Professional project management
• You maintain direct relationships with trades
• Transparent pricing

When CM Makes Sense

• Large projects where you want cost transparency
• When you have some project management capability but need support
• Ongoing capital improvement programs
• Property managers with multiple projects

Common Mistakes

1. Hiring a GC for Simple Projects

Paying 20% overhead for a single-trade project is wasteful. If you just need a roof replaced, hire a roofer.

2. Managing Complex Projects Without a GC

Trying to coordinate 5 trades without experience leads to conflicts, delays, and quality issues that cost more than a GC would have.

3. Not Verifying Licenses and Insurance

Whether hiring a GC or subcontractor, always verify licenses and insurance directly with issuing authorities.

4. No Written Contracts

Verbal agreements lead to scope disputes, payment conflicts, and quality issues. Always use written contracts with clear scopes, pricing, and terms.

5. Choosing Based on Price Alone

The lowest bid isn't always the best value. Consider experience, references, communication, and reliability alongside price.

Conclusion

The decision between a general contractor and specialty subcontractors depends on project complexity, your management capacity, timeline, and risk tolerance. For simple, single-trade projects, go direct to subcontractors. For complex, multi-trade projects requiring coordination and accountability, a GC provides value that justifies the cost. For larger projects where you want cost transparency, consider a construction management approach.
