The GC vs. self-manage decision affects budget, timeline, and stress for every major GTA renovation. Here is an honest 2026 breakdown.
General Contractor: What the Premium Buys
A GC adds 15-25% overhead and profit but delivers: project management, trade scheduling, single accountability, and established subtrade relationships. For projects above $75,000 involving multiple trades, the GC premium almost always pays for itself in avoided mistakes.
Self-Managing Subtrades: Real Risks
- Trade scheduling conflicts cause expensive idle time
- Trades blame each other for deficiencies with no single accountability
- Insurance gaps leave the homeowner liable for injuries
- Homeowner time cost (20-40 hours/week) typically exceeds the GC savings
- Permit inspection coordination becomes the homeowner’s job
When Self-Managing Can Work
Single-trade projects (flooring, paint, a single bathroom with no relocations) can be owner-managed effectively. You need to be available during the day. Never self-manage electrical, structural, or projects requiring permits without deep experience.
