When you hire someone to remodel your kitchen or replace your roof, you're stepping into a world with its own hierarchy. Two roles come up constantly: the general contractor and the subcontractor. Most homeowners use the terms interchangeably, but they mean very different things - and mixing them up can lead to budget surprises, accountability gaps, and headaches you didn't see coming.

Here's what each role actually does, how they work together, and what it means for your project and your wallet.

What a General Contractor Actually Does

A general contractor (GC) is the person or company you hire directly to manage a construction or renovation project from start to finish. They're your main point of contact - the one who holds the contract with you and takes responsibility for delivering the finished work.

Their job covers a lot of ground. A GC pulls permits, builds the project schedule, coordinates workers on site, orders materials, and makes sure everything meets local building codes. When something goes wrong, they're the ones you call.

General contractors carry their own license and insurance, and they're legally responsible for the project outcome. The majority of states require some type of state licensing program for general contractors, with common requirements including trade knowledge exams, proof of experience, and insurance verification. If a wall gets framed incorrectly or a subcontractor damages your flooring, your GC is accountable to you - not the individual worker who made the mistake.

When You Actually Need a General Contractor

---

You need a GC when a project involves multiple trades, significant structural work, or anything requiring permits. Full bathroom remodels, home additions, new builds, major kitchen renovations - these jobs require someone to orchestrate moving parts. Electricians, plumbers, tile setters, and carpenters all need to show up in the right order, and that coordination doesn't happen on its own.

For smaller, single-trade jobs, you can often hire a specialist directly and skip the GC layer entirely.

What a Subcontractor Does

A subcontractor is a specialist brought in to handle a specific scope of work within a larger project. They don't work for you directly - they work for the general contractor, who hired them to cover a particular trade.

Common subcontractors include electricians, plumbers, HVAC technicians, drywall installers, roofers, painters, and tile setters. Each one focuses on their specialty and typically moves on once their portion is done.

Subcontractors are usually licensed in their specific trade - an electrician holds an electrical license, a plumber holds a plumbing license. They carry their own insurance too, though your GC should verify that before anyone sets foot on your job site.

The Accountability Chain That Actually Matters

Here's the part that catches homeowners off guard: you have no direct contract with the subcontractors working on your project. Your contract is with the GC. So if a plumber does shoddy work, you go to your GC to resolve it - not the plumber.

That chain of accountability is a feature, not a flaw. A good GC vets their subs, manages their work, and stands behind the results. But it also means your choice of GC matters enormously, because their subcontractor relationships have a direct impact on your project quality.

How GCs and Subcontractors Work Together

Think of the GC as the project manager and the subs as the specialists. The GC bids the job, signs the contract with you, and then either uses their own crew for certain work or brings in subcontractors for the trades they don't self-perform.

When presenting your overall project cost, the GC marks up the subcontractors' bids. General contractors typically add 10-20% on top of subcontractor prices to cover coordination, warranty exposure, and overhead allocation. That markup covers their time coordinating the job, managing risk, and standing behind the finished work. It's a normal, legitimate part of how construction pricing works.

A typical project flow looks like this:

• You hire a GC and sign a contract

• The GC schedules subcontractors by trade, in the right sequence

---

• Each sub completes their portion and leaves the site

• The GC inspects and approves each phase before the next begins

• You communicate exclusively with the GC about progress, issues, and changes

Can You Hire Subcontractors Directly?

Yes - and sometimes it makes sense. If you need a single trade, like a licensed electrician to add a circuit or a plumber to replace a water heater, hiring that specialist directly cuts out the GC layer and the markup that comes with it.

On larger jobs, though, this approach carries real risk. Without a GC, you become the project manager. You're responsible for scheduling trades in the right order, making sure each phase is ready before the next one starts, and sorting out any disputes between workers. That's a significant time commitment, and sequencing mistakes can easily cost more than whatever markup you saved.

Most homeowners who try to act as their own GC on a multi-trade project find it far more demanding than they expected.

What to Verify Before Hiring a GC

Not all general contractors operate the same way. A few things worth checking before you sign anything:

License and insurance. Your GC should hold a valid contractor's license in your state and carry both general liability insurance and workers' compensation. Ask for certificates - not just verbal confirmation.

Subcontractor vetting. Ask how they select their subs. Do they rely on the same trusted specialists job after job, or do they pull from whoever's available? GCs with long-standing subcontractor relationships tend to produce more consistent results.

Lien waivers. If a GC doesn't pay their subcontractors, those subs can file a mechanic's lien against your property - even if you paid the GC in full. These liens create a cloud on your home title, making it difficult to sell or refinance. Requiring signed lien waivers as work is completed protects you from that scenario.

Change order process. Change orders affect over 75% of construction projects, with the average project experiencing cost increases of 10-15%. A professional GC documents every change in writing, with a price attached, before proceeding. Be cautious of anyone who handles changes verbally.

FAQs

What's the main difference between a general contractor and a subcontractor? A general contractor manages the entire project and holds the contract with you. A subcontractor is a trade specialist hired by the GC to complete a specific portion of the work. You typically have no direct contract with subcontractors.

Do I need a general contractor for every home project? No. Single-trade jobs - like hiring an electrician or a plumber for a focused repair - often don't require a GC. You need one when a project involves multiple trades, permits, or significant coordination across phases.

Can a subcontractor put a lien on my home? Yes. If a general contractor fails to pay a subcontractor, that sub may have the legal right to file a mechanic's lien against your property. Requiring signed lien waivers as work progresses is the standard way to protect yourself.

How does a general contractor price their work? A GC typically marks up subcontractor bids to cover coordination, risk management, and project oversight. This markup is a normal part of construction pricing and reflects the value of having one accountable party managing the entire job.

Should I hire subcontractors directly to save money? On single-trade jobs, it can make sense. On multi-trade projects, acting as your own GC means taking on scheduling, sequencing, and dispute resolution yourself - and the time and risk involved often outweigh the savings.

How do I verify that a general contractor is properly licensed? Ask for their license number and check it through your state's contractor licensing board. Also request current certificates of insurance for general liability and workers' compensation before any work begins.

What happens if a subcontractor does poor work on my project? Your recourse is with the general contractor, not the subcontractor directly. Your contract is with the GC, and they're responsible for the quality of every trade on your job site. Document the issue in writing and request a resolution through your GC.

Knowing who does what on your project isn't just useful background - it directly shapes how you hire, what you verify, and how you protect yourself financially. Choose your GC carefully, understand the sub relationship, and make sure every agreement is in writing before work starts.
