Why Hire a General Contractor (and When You Don't Need One)

Every renovation in Collin County starts with the same quiet question: do I really need to hire a general contractor, or can I save the markup and run this myself? It's a fair question. A GC isn't free, and not every project needs one. But the honest answer depends less on the size of your budget than on how many moving parts your project has, and on who's standing behind the whole thing when something goes wrong six months later.

So here's the real case for (and against) hiring a general contractor, written for homeowners in Allen, Plano, Frisco, McKinney, and the rest of Collin County, including the single-trade jobs where you can skip the GC entirely.

What a general contractor actually does

A specialty contractor sees their slice. A pool builder sees the pool. A roofer sees the roof. A kitchen-only outfit sees the kitchen. A general contractor sees the whole house, and the whole lot it sits on.

The GC's real job isn't swinging a hammer. It's coordination and accountability: pulling permits, sequencing trades in the right order, making sure the electrician doesn't rough-in before the framing inspection passes, catching the drainage problem before it cracks your slab, and being the single name on the contract when something needs to be made right.

On a one-trade job, that coordination isn't worth much. On a multi-trade job, it's the difference between a project that finishes and one that stalls.

The jobs that don't need a general contractor

Let's be honest, because most contractor websites won't: plenty of home projects don't need a GC at all. If your project is a single trade, self-contained, and doesn't touch structure or the permit office, hire the specialist directly and keep the markup.

You generally don't need a general contractor for:

• A straight roof replacement — one licensed, insured roofer, one scope.
• A water heater swap, a few fixtures, or a single-room repaint.
• New flooring in an existing footprint (LVP, tile, carpet).
• A fence, a deck refresh, or standalone landscaping.
• Cosmetic swaps — cabinet refacing, a new vanity, light fixtures, countertops — that don't move plumbing, electrical, or walls.

The rule of thumb: one trade, no structural change, no permit? You probably don't need a general contractor. Hire the specialist, verify their license and insurance, and go.

The jobs that do need a general contractor

The moment your project involves more than one trade working in sequence, or touches structure, or needs a permit and inspections, the calculus flips. That's when the "whole picture" stops being a slogan and starts being the thing that protects you.

You want a GC for:

• Whole-home renovations and anything that opens up walls.
• Additions and second-story build-ups (structural + MEP + permits).
• Ground-up custom builds and ADUs.
• Kitchen remodels that move plumbing, gas, or walls — which is most of them.
• Any project stacking three or more trades — demo, framing, electrical, plumbing, HVAC, finishes — that have to happen in the right order.
• Backyard and outdoor-living projects where a pool, decking, grading, and drainage all affect the same soil.

Here's what a GC is actually protecting you from on those jobs.

What a general contractor really protects you from

Permits and inspection sequencing

Texas is unusual: there is no statewide general-contractor license. General contracting is regulated city by city, while the specialty trades (electrical, plumbing, HVAC) are licensed at the state level. That means permitting rules and processes differ across Collin County, and it's on someone to know each city's.

In Allen, permits run through the city's Citizen Self-Service (CSS) portal, with the Building and Permitting division at 305 Century Parkway. McKinney runs its own CSS portal and typically takes on the order of two to three weeks for a first residential plan review. Plano, Frisco, Prosper, Wylie, Fairview, and Richardson each have their own portals, fees, and inspection sequences.

A permit isn't just paperwork. It's a series of inspections that must pass in order — foundation before framing, framing before walls close up, rough-in MEP before drywall. Miss the sequence and you're re-opening finished walls. A GC owns that calendar. When you self-manage, you own it too, including the day an inspector red-tags the work and every downstream trade has to be rescheduled. (See our Collin County permit guide for the city-by-city breakdown.)

The whole lot: clay, grading, and drainage

North Texas sits on expansive clay. It swells when it's wet, shrinks when it's dry, and that movement is the leading controllable cause of foundation problems across DFW. The fix is almost always water management: proper grading away from the house (code generally calls for the ground to fall about six inches within the first ten feet) plus drainage that actually moves water off the lot.

This is where the whole-picture advantage gets concrete. A pool builder optimizes the pool. A patio company optimizes the patio. Neither one is responsible for what happens when new impervious cover, a re-graded yard, and your existing foundation all fight over the same water. A GC coordinates grading and drainage across the entire lot as one system, because to your slab, it is one system. (More on that in building on North Texas clay.)

Liens: the risk hiding in "I'll just manage the subs myself"

Here's the part most DIY project managers don't see coming. Under Chapter 53 of the Texas Property Code, a subcontractor or supplier who doesn't get paid can file a mechanic's lien against your home, even for work you thought was already covered. If you hire and pay a GC, the GC carries the responsibility for paying the subs beneath them. If you hire the subs directly, that exposure lands on you. Pay your framer, but your framer doesn't pay their lumber supplier, and that lien can still attach to your house.

Single-point payment isn't just convenient. It's a liability firewall. (Can a contractor put a lien on your house in Texas?)

One warranty instead of a finger-pointing contest

When five specialists each handle their slice and the bathroom leaks a year later, whose fault is it? The plumber blames the tile-setter, the tile-setter blames the waterproofer, and now you're the general contractor: mediating, and paying. With one GC, there's one contract, one warranty, and one name responsible for making it right. Accountability is the feature you don't notice until you need it.

Resale and disclosure

Unpermitted work follows the house. Texas Property Code Section 5.008 requires sellers to complete a Seller's Disclosure Notice that asks, directly, about additions and alterations and whether permits were obtained. Check the wrong box and you're exposed to fraud claims, and under the Deceptive Trade Practices Act, potentially treble damages. Unpermitted additions also routinely surface at appraisal and financing, where they can quietly shrink the value of the work you paid for. Permitted, inspected work is an asset. Unpermitted work is a disclosure problem waiting at closing.

Is the markup worth it?

The honest number: a general contractor typically adds somewhere in the range of 15% to 25% on top of hard costs, split between overhead and profit. The exact figure varies by firm, scope, and market, and some sources put today's residential markups higher.

But the right comparison isn't cost with a GC versus no cost. It's managed cost versus unmanaged cost. That markup buys sequencing that prevents rework, buying power on materials, subs who show up because they want the next job, lien protection, and one accountable party. Self-managing means you absorb the coordination — the change orders, the idle-trade days, the re-inspections — usually while holding down a full-time job. Sometimes that trade is worth it. On a complex project, the "savings" often evaporate the first time the schedule slips. (The full managed-vs-unmanaged breakdown here.)

How to vet a general contractor in Collin County

Because Texas has no state GC license to look up, verification matters more here, not less. Before you sign:

• Confirm general liability insurance and ask to be named as additional insured.
• Verify they're bonded and registered in your city where that's required.
• Check that specialty work runs through state-licensed trades (electrical, plumbing, HVAC).
• Get the scope, allowances, and payment schedule in writing, and make sure the GC, not you, contracts the subs.
• Ask who pulls the permits. The right answer is always "we do."

Frequently asked questions

Do I need a general contractor for a kitchen remodel?

It depends on scope. If you're only swapping countertops, cabinet fronts, or fixtures without moving anything, you can often hire specialists directly. But most kitchen remodels move plumbing, gas, or walls and pull multiple trades in sequence, and those need a GC to coordinate and permit the work.

Does Texas require a general contractor to be licensed?

There is no statewide general-contractor license in Texas. General contracting is regulated at the city level, while electrical, plumbing, and HVAC trades are licensed by the state. Because there's no state license to verify, confirm a GC's insurance, bonding, and city registration yourself before signing.

Can a subcontractor put a lien on my house if I manage the project myself?

Yes. Under Chapter 53 of the Texas Property Code, an unpaid subcontractor or supplier can file a mechanic's lien against your home, even for work you thought was paid for. Hiring subs directly shifts that payment responsibility, and the exposure, onto you rather than a general contractor.

Do I need a permit to remodel in Allen or McKinney?

Structural changes, additions, and new or relocated plumbing, electrical, or HVAC generally require a permit. Purely cosmetic swaps usually don't. Allen processes permits through its Citizen Self-Service portal; McKinney uses its own CSS portal and typically takes about two to three weeks for a first residential plan review.

Is a general contractor's markup worth it?

For a single-trade job, often not. For a multi-trade, permitted, or structural project, usually yes. The markup (commonly around 15% to 25%) buys sequencing, lien protection, buying power, and single-point accountability that self-managing can't replicate, which is why the honest comparison is managed cost versus unmanaged cost.
