Overview

A general contractor coordinates every trade, permit, inspection, material order, and schedule on a renovation so the homeowner deals with one person instead of eight. The role is part builder and part project manager, and on a well-run job most of the value is invisible because it shows up as things that did not go wrong. You need a general contractor when a project crosses more than one trade, touches structure, or requires a permit. You do not need one for a single-trade job like replacing one floor, swapping a vanity, or repainting a room, and hiring one for that work usually just adds cost. Knowing which side of that line your project falls on saves money either way.

The Job Behind the Title

Coordinating Trades, Permits, and Inspections

On a full bathroom renovation there are usually five or six separate skill sets involved: demolition, framing, plumbing, electrical, waterproofing and tile, and finish carpentry. Each one has to happen in a specific order, and several of them cannot start until an inspector has signed off on the one before.

The general contractor owns that sequence. Booking the plumber for the right day, making sure the electrician is not roughing in the same cavity at the same time, calling the inspection at the right stage, and having the tile on site before the waterproofing is cured. Miss one link and the whole chain slips by a week or more, because trades who show up to a job that is not ready go to their next job instead.

The permit side works the same way. Someone has to know what requires a permit, get the drawings produced, submit the application, respond to the building department, and call the inspections in the right order. That is the GC.

Owning the Schedule and the Material Orders

A renovation is a supply chain problem as much as a construction problem. Cabinets have lead times. Countertops cannot be templated until cabinets are physically installed. Tile has to be on site before the tiler is, and it has to be the right quantity, because dye lots vary between orders and a mid-job reorder can arrive visibly different.

The general contractor tracks all of it against the calendar and tells you when a decision has to be made. When homeowners say a renovation "stalled," the cause is almost always a material that was ordered too late or a selection that was not finalized in time.

Carrying the Liability, Insurance, and WSIB

This part is boring right up until it matters. A general contractor carries liability insurance and WSIB coverage for the work happening on your property.

If someone is injured on an uninsured job at your house, or if uninsured work causes damage, that exposure can land on the homeowner. It is a real risk and it is one of the concrete reasons a properly insured contractor costs more than the cash quote.

When You Need a GC and When You Do Not

Multi-Trade and Structural Work: Hire a GC

The rule of thumb is straightforward. If the job needs more than one trade, touches anything structural, or requires a permit, hire a general contractor.

That covers kitchens, full bathrooms, basement finishing, additions, removing or moving walls, and any project where plumbing or electrical is relocating. In all of those, the coordination is a real job. Trying to run it yourself while working full time is how projects stretch from eight weeks to five months.

Single-Trade Jobs: Hire the Trade Directly

If the work is one trade, in one room, with no permit and no structural change, call that trade directly and keep the coordination cost.

Replacing flooring in a bedroom, swapping a vanity and faucet with the plumbing staying put, retiling a backsplash, painting, replacing an existing light fixture. These are single-trade jobs. A good general contractor will tell you the same thing rather than take the work.

The Grey Zone and How to Decide

Plenty of projects sit in between. A bathroom where the tub becomes a shower in the same footprint. A basement that is already framed and just needs finishing. A kitchen where the cabinets change but nothing moves.

Three questions sort it out. Does anything mechanical move, meaning plumbing, electrical, or ductwork changing location. Does anything structural change, meaning walls, beams, or openings. Does it need a permit. One yes usually means bring in a general contractor. Three noes usually means you do not need one.

What It Looks Like When the Owner Is the GC

One Point of Contact From Quote to Final Walk-Through

On most renovation companies there is a handoff. A salesperson quotes the job, a project manager runs it, and a crew builds it. Every handoff is a chance for the thing you actually asked for to get lost.

When the owner is the general contractor, that handoff does not exist. The person who walked your house, understood what you wanted, and priced it is the same person on site holding the tools. Nothing gets translated through three people.

Decisions Made On Site Instead of Escalated

Renovations generate small decisions constantly. The joist is not where the drawing assumed. The tile layout leaves an awkward cut at the doorway. There is an unexpected pipe in the wall you wanted opened.

On a job where the owner is on site, those get decided in the moment, usually with you standing there. On a job run remotely, they get photographed, texted, escalated, and waited on, and the crew works around the problem or downs tools until an answer comes back. That delay is where days disappear.

Frequently Asked Questions

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

A general contractor holds the contract with the homeowner and is responsible for the entire project: scheduling, permits, inspections, materials, and the finished result. A subcontractor is a specialist hired by the general contractor for one portion of the work, such as plumbing, electrical, or HVAC. The subcontractor answers to the general contractor, not to the homeowner.

Do I need a general contractor for a bathroom renovation in Ontario?

For a full bathroom renovation, yes in most cases. A gut bathroom involves demolition, framing, plumbing, electrical, waterproofing, tile, and finish work, with inspections between several of those stages. For a surface update where nothing moves, such as a new vanity in the same location and new paint, you can hire the individual trades directly.

What percentage does a general contractor charge in Ontario?

General contractor fees in Ontario typically run 10 to 20 percent of project cost, either built into the quoted price or shown as a separate management fee. Some contractors also mark up subcontractor quotes on top of that, which is worth asking about directly since it is rarely itemized. DAPCO passes trade quotes through at cost.

Can I act as my own general contractor on a renovation?

You can, and for a small or simple project it can make sense. You take on scheduling every trade, sequencing the work correctly, pulling permits, booking inspections, ordering materials on time, and the liability if something is built out of order or fails. Most homeowners who try it on a multi-trade renovation find the delays and rework cost more than the fee they saved.
