What Does a General Contractor Actually Do? A Plain-Language Guide

A general contractor (GC) is the one party you hire to plan, coordinate, and deliver a construction project from start to finish. In plain terms: a GC turns drawings into a buildable plan and a real budget, hires and schedules the trades in the right order, pulls the permits and hosts the inspections, buys the materials, keeps the job site safe, and stands behind the finished work with a warranty. They are your single point of contact while the project runs, and the single name accountable when something has to be made right.

That's the short answer. The longer one is worth reading, because "coordination" is a vague word hiding an enormous amount of specific, unglamorous work — and understanding that work is how a homeowner in Allen, Plano, Frisco, or McKinney decides exactly what they're paying for. (If your real question is whether that work is worth the fee at all, we make that full case in why hire a general contractor; this guide is about what the job itself involves.)

The general contractor's job, in one list

Strip away the jargon and a residential GC does eight things. On a single-trade project, most of them barely register. On a permitted, multi-trade remodel or addition, every one of them is load-bearing:

• Coordinates the design and engineering so the plans are buildable, code-compliant, and priced before anyone swings a hammer.
• Estimates and owns the budget — one number for the whole scope, with allowances for the choices you haven't made yet.
• Hires, schedules, and sequences the trades so each crew arrives to a site that's ready for them, in the order the work has to happen.
• Pulls the permits and hosts the inspections, and answers to the city when the inspector shows up.
• Buys the materials and manages lead times, deliveries, and where it all gets staged.
• Keeps the site safe. On a job with multiple crews, federal OSHA rules for multi-employer worksites treat the party with general supervisory authority — usually the GC — as the "controlling employer," responsible for reasonable care that the site stays free of hazards. It's a legal duty, not a courtesy.
• Is your single point of contact — one phone number instead of a dozen.
• Stands behind the finished work with a warranty, and a name that's still there a year later.

Everything below is those eight jobs, playing out in order, on a real project.

Walk a real addition, stage by stage

The clearest way to see what a GC does is to follow one down a job. Take a common Collin County project: a primary-suite addition — a new bedroom, bathroom, and closet bumped off the back of the house. It touches design, structure, all three major trades, and the city. Here's what the GC is doing at each stage while the trades do the building.

Before anything is built: design, budget, and the contract

Long before demolition, the GC is turning an idea into a plan. On a design-build project that means coordinating the architectural drawings and — critically on North Texas clay — a structural engineer's stamped foundation design, because an addition ties new footing into an existing slab that already moves with the seasons. The GC prices the whole scope into one budget, sets allowances for finishes you haven't picked yet (tile, fixtures, cabinets), and puts it in a written contract with a payment schedule. This is also where a good GC levels bids, so you're comparing real, apples-to-apples scopes instead of one lowball number that quietly leaves out half the job.

For that coordination, a general contractor adds a markup — commonly 15%–20% of project cost, and typically higher on a remodel, where 2026 industry benchmarks put it around 20%–30% (a market range, not a quote from The Remo Guys). Naming what that fee pays for is this guide's job; whether it's worth it is the flagship's. Want a rough range before you talk to anyone? Our cost estimator is a reality check, not a quote.

Permits: turning plans into a legal green light

With plans in hand, the GC submits to the city and pulls the building permit. In Collin County that means a different portal, fee schedule, and review timeline in Allen than in Plano, Frisco, or McKinney (we compare them in the Collin County permit guide). The permit isn't paperwork you file once — it's a commitment to a sequence of inspections that must pass in order, and the GC owns that calendar. One detail worth knowing: Texas has no statewide residential general-contractor license, so a GC's standing isn't a state card. It's their insurance, bonding, and city registration, plus the state-licensed trades working under them. The right answer to "who pulls the permit?" is always "we do."

Foundation and framing: getting the bones right

Now the building starts, and the GC's role becomes sequencing and quality control. The site is graded and drained so water moves away from the house — code generally wants the ground to fall about six inches over the first ten feet — then the new foundation is formed, poured, and has to pass a foundation inspection before framing can begin. Framers raise the walls and tie the new roofline into the old one; a framing inspection follows. The GC schedules each crew to hit the site the day the previous stage is signed off, and catches the problems that never show up on paper — a mis-sized header, a roof tie-in that will leak — before they're buried behind drywall.

Rough-in: three licensed trades, one sequence

This is the stage that most needs a conductor. Three state-licensed trades work through the open walls in a coordinated order: the plumber (licensed by the Texas State Board of Plumbing Examiners), the electrician, and the HVAC contractor (both licensed by the Texas Department of Licensing and Regulation, or TDLR). Note the distinction this whole industry runs on: those trades are genuinely state-licensed, while the GC coordinating them is not, because Texas doesn't license GCs. Each trade roughs in its lines, then the city inspects the rough-in before anything is closed up. Get the order wrong — insulate before the rough-in passes — and someone is re-opening a finished wall. The GC's job is to make sure that never happens.

Close-up and finishes: where coordination shows

Once the rough-in inspections pass, insulation and drywall close the walls, and the finish trades line up: cabinets, then countertops (templated only after the cabinets are set), tile, paint, flooring, and trim, with the plumber and electrician returning to set fixtures. This is where material lead times the GC ordered weeks earlier pay off — a cabinet order placed late idles every trade behind it. The GC is choreographing deliveries, keeping crews off each other's wet paint and fresh tile, and running the quality checks between handoffs.

Final inspections, punch list, and warranty

At the end, the GC schedules the final inspections; for added living space, the city may issue a certificate of occupancy (or a final sign-off) confirming the room is legal to use. Then the GC walks the finished job with you, builds a punch list of the small misses, and gets them corrected. When the contract closes, the warranty is what remains: one accountable party to call if something moves or leaks, instead of five specialists pointing at each other.

What a general contractor does NOT do

Just as useful is knowing where the role stops — because a "GC" who blurs these lines is a warning sign:

• A GC is not your structural engineer or architect. On clay soil especially, the stamped foundation and structural design is a licensed engineer's work. The GC coordinates it; they don't sign it.
• A GC doesn't personally perform the licensed trade work. They hire and manage state-licensed electricians, plumbers, and HVAC techs. Anyone offering to "just do the electrical myself" without the licensed trade is cutting a corner you'll inherit.
• A GC is not the city inspector. They schedule and host inspections; the city's inspector has final say on code.
• A GC isn't required for every job. A single-trade, non-permitted, cosmetic project — a repaint, new flooring, a like-for-like water-heater swap — usually doesn't need one, and an honest builder will tell you so. We do, in do you need a general contractor to remodel in Allen.
• A GC shouldn't hand you the liability. If a contractor asks you to pull the permit yourself (an owner-builder permit) so they don't have to, understand what you're accepting: the code responsibility and the lien exposure. That's the self-managing path, and its real cost is laid out in design-build vs. managing your own contractors.

How to know you've got a real one

Because there's no state license to look up, verifying a GC in Texas falls to you — and it matters more here, not less. Before you sign, confirm general liability insurance (ask to be named as additional insured), confirm the GC is bonded and registered in your city where that's required, and check that the specialty work runs through those state-licensed electricians, plumbers, and HVAC techs, with the GC (not you) holding the contracts with them. Our Texas contractor hiring checklist turns that into a step-by-step vetting list.

The one-sentence version

A general contractor is the person who turns a set of drawings and a budget into a finished, permitted, warrantied space — by owning the plan, the schedule, the trades, the city, the materials, and the accountability, so you only have to own the vision.
