What is the difference between a general contractor and a subcontractor?

A general contractor manages the entire project — hiring subs, pulling permits, scheduling work, and serving as your single point of accountability. Subcontractors are specialists (plumbers, electricians, framers) who perform a defined trade. You typically have a contract with the GC, not the subs.

Can I hire subcontractors directly to save money?

Yes, but it means you become the de facto general contractor. You're responsible for scheduling, coordination, permits, and resolving conflicts between trades. This works for simple single-trade projects but creates serious coordination risk on multi-trade remodels.

Who is liable if a subcontractor does bad work?

Your contract is with the GC, so the GC is liable for subcontractor work quality. If a plumbing sub installs a pipe incorrectly and it leaks, you call the GC — not the sub — to make it right. This is one of the core values a GC provides.

What does a subcontractor markup look like?

General contractors typically mark up subcontractor invoices 10–20%. On a $20,000 electrical job, the GC might pay the electrician $20,000 and charge you $22,000–$24,000. This markup covers GC coordination, warranty, and liability absorption.

General Contractor vs. Subcontractor: What's the Difference and Why It Matters

April 25, 2026

The Organizational Structure of a Construction Project

When you hire a general contractor, you're hiring a project manager, not just a builder. The GC's job is to decompose your renovation into discrete trade scopes, hire specialists for each scope, sequence their work correctly, and hold them accountable to a single standard of quality. You have one contract and one point of contact. The GC handles the rest.

Subcontractors are the specialists who actually perform the physical work. Each has deep expertise in a single trade but typically lacks the coordination skills, insurance breadth, or business infrastructure to manage a full renovation project on their own.

What General Contractors Actually Do

Beyond swinging a hammer (which many GCs do only minimally), a general contractor's core work includes:

Scope development: Translating your goals into a buildable plan with material specs and sequencing
Permitting: Preparing and submitting permit applications, scheduling inspections, and ensuring code compliance
Subcontractor procurement: Sourcing, vetting, and contracting specialist trades
Scheduling: Sequencing work so framing completes before drywall, rough-in completes before insulation, etc.
Quality control: Inspecting subcontractor work before covering it up
Payments: Collecting from you and disbursing to subs in a structured draw schedule
Lien management: Obtaining lien waivers from subs to protect your property title
Problem resolution: Handling unforeseen conditions, design conflicts, and trade disputes

Common Subcontractor Trades on a Remodel

A typical kitchen or bathroom remodel involves 6–10 different subcontractors. Most homeowners are surprised by how many specialists touch their project:

Demo crew
Structural/framing carpenter
Plumber (rough-in and finish)
Electrician (rough-in and finish)
HVAC technician
Insulation installer
Drywaller
Tile setter
Cabinet installer
Painter

Each trade must complete their work in the right sequence and coordinate around the others' timelines. A GC manages this orchestration full-time.

When to Hire a GC vs. Going Direct to Subs

Hiring subcontractors directly — called "owner-builder" or "self-managing" — makes sense in narrow situations:

Single-trade projects: replacing a water heater, painting, refinishing floors
You have construction management experience and time to be on-site daily
Projects under $5,000 with one or two tradespeople

Going direct creates serious risk on any multi-trade project because you absorb all coordination responsibility. If the electrician runs conduit through where the plumber planned their drain, you're the one resolving it — not a GC. Missed sequencing adds weeks and frequently costs more than the GC's markup would have.

Protecting Yourself From Sub Liens

One of the most important GC functions is lien protection. In most states, subcontractors and material suppliers can file a mechanic's lien against your property if your GC fails to pay them — even if you paid the GC in full. A responsible GC provides conditional and unconditional lien waivers from each sub with every draw payment. If your contract doesn't mention lien waivers, add that requirement before signing.
