What is design-build, and how is it different from hiring a general contractor?

Under design-build, design and construction sit under one contract with one firm. Traditionally — design-bid-build — you hire a designer or architect first, complete the design, then put the drawings out to contractors and select a bid. The practical difference is pricing feedback during design rather than after it, so the cost of a decision is known while the decision is still cheap to change. It also puts one firm in charge of resolving a conflict between the drawings and what can actually be built, instead of placing that between two firms with different contracts and leaving you to mediate.

Is design-build cheaper than the traditional route?

Not reliably, and we would not claim it. What it reduces is a specific and expensive failure: the bid coming back well over budget after the design is finished, when every remaining option is bad — redesign at your cost, cut scope from a plan conceived as a whole, or proceed over budget. It also tends to reduce change orders arising from drawings that cannot be built as drawn. Whether the total is lower depends on the project. The reliable claim is about cost certainty earlier, not a lower number.

When should I hire an architect instead?

When the design itself is the point. If you want a particular architect's work, hire that architect — design-build optimises for buildability and cost certainty, and if what you want is a specific design voice you should go and get it. Also when the scope can be fully specified in advance and you want several contractors pricing the identical thing, which design-bid-build does well. And when you specifically want the person specifying the work separated from the person pricing it; that is a reasonable preference, and design-build trades it for integration. Renovation tilts the other way mainly because renovation scope is discovered rather than specified.

What insurance should my contractor carry?

General liability, which covers damage to your property, and ideally workers' compensation, which matters because without it an injury on your job can become your exposure. Texas does not require private employers to carry workers' compensation, so its absence is not unlawful — but it is something you should know rather than assume. Verify it with a certificate of insurance sent to you directly by the insurer or agent, not a copy forwarded by the builder, and check that the coverage is current and that the limits are sensible relative to your project. This is the single most worthwhile piece of verification in a state with no GC licence.

How do I check a builder's references properly?

Ask for projects of comparable scope rather than their largest or their favourite, and ask for addresses you can go and look at. When you speak to a reference, skip whether they were happy and ask what surprised them, how changes to the scope were handled, whether the schedule moved and how they were told, and whether the final cost resembled the contract. Then ask the question that gets the most honest answer: would you use them again, and is there anything you would do differently. A reference who is positive but specific is worth more than one who is simply enthusiastic.

What are the warning signs of a bad contractor?

A large deposit before anything is mobilised. Pressure to start immediately or to decide today. Reluctance to pull permits, or a suggestion that the work does not need them when it plainly does. A lump-sum bid with a one-line scope and no quantities or specifications. No written change-order terms. Unwillingness to provide insurance verification from the insurer directly. A bid markedly below the others with no explanation of what is different. Cash-only arrangements. And one that is easy to miss: vagueness about who will actually run the job, when the person you have been talking to is the reason you were reassured.

Who pulls the permits, the homeowner or the contractor?

The contractor should, and a builder asking you to pull them in your own name is worth questioning. Permits carry responsibility for the work complying with code; if they are in your name, that responsibility is yours, and so is the exposure if the work fails inspection or is later found to be unpermitted. In Fort Worth, a project of any real scope typically needs a building permit plus separate electrical, plumbing and mechanical permits, each with its own inspections. A builder who treats permitting as routine rather than as an obstacle is telling you something useful about how they work.

What should be in a renovation contract?

A written scope specific enough that you could identify a departure from it, with the drawings and specifications referenced as part of the agreement. Allowances stated with their values. A payment schedule tied to completed and verified stages rather than dates. Written change-order terms, including how they are priced and whether schedule impact is included. The schedule, with what causes it to move. Insurance obligations. Warranty terms and their duration. How disputes are handled. And who the project's point of contact is. If something was agreed verbally and matters to you, it belongs in the document — not because anyone is expected to act in bad faith, but because memories of a conversation six months ago diverge honestly.

Choosing a Builder

Design-Build or a General Contractor: How the Two Routes Differ, and How to Vet Either

The difference is not the quality of the work. It is who owns the gap between the drawings and what can be built for your budget. Under design-build one firm owns it; under the traditional route it sits between your architect and your contractor, and you are the one standing in it. Which is better depends on how your project is likely to go wrong.

Reviewed November 4, 2026

What design-build actually changes

In the traditional arrangement — design-bid-build — you hire a designer or architect, the design is completed, the drawings go out to contractors, and you select a bid. Two separate contracts, two separate firms, and a handover between them.

Under design-build, design and construction sit under one contract. The practical consequence is pricing feedback during design rather than after it: the cost of a decision is known while the decision is still cheap to change.

That matters because of where the traditional route usually fails. It is not bad design or bad building; it is the bid coming back substantially over budget after the design is complete. At that point the options are all bad — redesign at your cost, cut scope from a plan that was conceived whole, or proceed over budget. The time spent getting there is spent.

The second thing it changes is who owns a conflict between the drawings and the field. Where a detail cannot be built as drawn, design-build resolves it internally. Under separate contracts that becomes a conversation between two firms with different contracts and different interests, mediated by you.

When the traditional route is better

Design-build is not the right answer for every project, and it is worth being straightforward about when it is not.

When the design itself is the point. For an architecturally ambitious project where you want a specific architect's work, hire that architect. Design-build optimises for buildability and cost certainty; if what you want is a particular design voice, go and get it.

When you want competitive bidding on a fixed design. If the scope can be fully specified in advance and you want several contractors pricing the identical thing, design-bid-build does exactly that. It works best where the scope is genuinely knowable up front — which is more often true of new construction than of renovation.

When an independent check is the priority. Some homeowners want the designer's interests separated from the builder's, so that the person specifying the work is not the person pricing it. That is a reasonable preference, and the honest response is that design-build trades it for integration. Both are real.

Renovation tilts toward design-build mainly because renovation scope is discovered rather than specified. You cannot fully define work whose extent depends on what is behind the drywall, and a fixed design priced before anyone has opened a wall is a design that will change.

Verifying a builder in Texas

Texas does not license general contractors at state level. There is no state GC licence to check, which surprises homeowners who have renovated elsewhere, and it means the verification work falls to you.

What is licensed at state level are the trades: electricians through the Texas Department of Licensing and Regulation, and plumbers through the Texas State Board of Plumbing Examiners. Those licences are verifiable online, and the licence number of the person actually doing the work is a fair thing to ask for.

Insurance is the item most worth verifying properly, and the way to verify it is a certificate of insurance sent to you directly by the insurer or agent — not a copy forwarded by the builder. General liability covers damage to your property; workers' compensation matters because, without it, an injury on your job can become your exposure. Texas does not require private employers to carry workers' compensation, so its absence is not unlawful and is worth knowing about.

Permits are the other verifiable signal. Work that should be permitted and is not leaves you with an unpermitted alteration on your property, which surfaces at resale and can complicate an insurance claim. A builder who pulls permits as a matter of course is telling you something about how they work.

A certificate of insurance sent directly by the insurer or agent
General liability, and whether workers' compensation is carried
Trade licence numbers for the electrical and plumbing work, verifiable with the state
Who pulls the permits, and whether permitted work is permitted as standard
References from projects of comparable scope — not their largest or their favourite
Addresses of completed work you can go and look at
Whether the people you met will be the people running your job
A written scope, written change-order terms, and a stage-based payment schedule

The questions that actually tell you something

Most vetting questions have an obvious right answer, so they reveal little. The useful ones ask about failure, because every builder has had projects go wrong and the informative part is what they did.

Ask what went wrong on a recent project and how it was resolved. Ask for a reference from a job that did not go smoothly. Ask how many projects they run at once and who is on site daily. Ask what happens when demolition reveals something that changes the scope — specifically, who decides and how it is priced. Ask how they handle a subcontractor whose work fails inspection.

Then ask the question most homeowners forget: how do you communicate during the project, and how often? The majority of renovation grievances are not about workmanship. They are about not knowing what is happening in your own house.
