Houston is not like other markets. If you are buying here remotely this is the thing that will cost you the most money if nobody tells you first.
In most states a general contractor has to be licensed. There is a baseline. A test. A credential that at minimum proves they sat down and learned something before they were legally allowed to take your money.
Texas has no GC licensing requirement.
None. Anyone can call themselves a general contractor in Houston tomorrow. No test. No experience required. No credential to check. Just a business card and a number that sounds good enough to win the job.
That changes everything about how you have to operate here.
In most markets you can hire a GC, hand them a project, and expect them to manage the scope, budget, timeline, and material selection. That model depends on the contractor actually knowing what they are doing. In a licensed state you have at least some assurance they passed a threshold of competence. In Texas you have nothing to verify except their track record and their word.
The real GCs in Houston are implementers. They are there to execute a plan that already exists, not to create one. If you walk in without a line item scope, a detailed budget, a realistic timeline, and material specifications already developed you are not going to get a professional project plan back. You are going to get a number that sounds right and a handshake.
That number will not reflect reality. It will reflect whatever it takes to win the job.
The change orders start the moment they are on site and you have no detailed scope to hold them to. At that point the leverage shifts entirely to the contractor and it does not come back.
Before you hire anyone in Houston for a project of any size you need a line item scope of work covering every trade, a budget built from actual costs not ballpark figures, a timeline with milestones, and material specifications with alternatives listed so lead time issues don't stop your project cold.
That document is what you hand a GC. Without it you are not managing a contractor. You are funding one.
In a licensed state you can lean on the credential a little. In Texas you better know what you are looking at before you hand anyone a check.
