When to Hire a General Contractor vs Specialty Contractors
General contractors cost more but provide coordination and accountability. Here’s how to decide if you need a GC or can manage the project yourself.
Quick Answer
Hire a GC when: 3+ trades involved, permits required, structural work, project over 2-3 weeks, or you lack time to manage. Self-manage when: single trade, simple scope, you have flexibility. GC markup is 15-25% but provides coordination and accountability.
What General Contractors Do
- Project management – coordinate all trades, manage schedule
- Hire and manage subcontractors – vetting, contracts, quality control
- Pull permits and schedule inspections – handle paperwork and compliance
- Order materials – coordinate deliveries with work schedule
- Quality control – ensure work meets standards
- Problem solving – handle unexpected issues
- Single point of accountability – one contract, one responsible party
When You Need a GC
| Situation | GC Recommended? | Why |
|---|---|---|
| Kitchen/bathroom remodel | Yes | Multiple trades (plumbing, electrical, carpentry) |
| Addition/structural work | Yes | Complex permits, engineering, liability |
| Whole-house renovation | Yes | Too complex to self-manage |
| New roof | Usually no | Single specialty trade |
| HVAC replacement | No | Single specialty trade |
| Flooring installation | No | Single trade, straightforward |
| Painting | No | Single trade, simple scope |
Hire a GC When…
- Project involves 3 or more trades
- Permits are required (structural, electrical, plumbing)
- Structural changes or load-bearing walls involved
- Project duration exceeds 2-3 weeks
- You work full-time and can’t be available for coordination
- You’re not comfortable managing contractors
- Budget exceeds $25,000-$30,000
Self-Manage When…
- Single trade involved (roofing, HVAC, flooring)
- Simple, well-defined scope
- No permits required or very simple permit
- You have flexibility to be available
- You’re comfortable managing contractors
- Budget is under $15,000-$20,000
The Real Cost of Self-Managing
Managing a multi-trade project yourself takes 10-20+ hours: getting quotes, coordinating schedules, being present, solving problems. Calculate what your time is worth. If a GC’s 20% markup costs $8,000 on a $40,000 project, is saving $8,000 worth 20+ hours of your time and stress?
GC Cost Breakdown
| Component | Typical Markup | What You Get |
|---|---|---|
| Overhead | 8-12% | Office, insurance, vehicles, staff |
| Profit | 8-15% | Business profit margin |
| Total Markup | 15-25% | Full project management |
Example: $50,000 Kitchen Remodel
- With GC: $50,000 total (GC handles everything)
- Self-managed: $40,000-$43,000 (you coordinate all subs)
- Your savings: $7,000-$10,000
- Your time investment: 20-40+ hours
- Your risk: Higher if something goes wrong
Questions to Ask Yourself
- Do I have time to get multiple quotes and coordinate schedules?
- Can I be available when contractors need decisions?
- Do I understand the sequence of trades (what comes first)?
- Am I comfortable confronting contractors about quality issues?
- Do I know how to verify work meets code?
- Can I handle problems that arise without expert help?
Hybrid Approach
Some homeowners use a hybrid approach:
- Hire GC for complex portions (structural, permit work)
- Self-manage simpler trades (painting, flooring after remodel)
- Act as your own GC but hire a consultant to review
