How to choose a custom home builder in South Texas: 7 questions to ask

Ask seven things before you sign with any builder: how long they have built in your county, who will run your job day to day, what the price includes in writing, how allowances and change orders work, how their draw schedule fits your lender, which documents Texas law requires them to give you, and whether you can talk to families they have built for. Clear written answers matter more than any rendering.

Why does the choice matter more in South Texas?

Three things make local experience worth more here than in most of the state.

• The soil. Much of the Valley sits on clay that swells when wet and shrinks when dry, so the slab has to be engineered to a soil report for your lot, not copied from the last job.
• The weather. Summers past 100°F keep the insulation and air conditioning working most of the year. Cameron County also sits inside the Texas Windstorm Insurance Association catastrophe area, where windstorm certification shapes framing, fastening and openings.
• The paperwork. Every city permits on its own terms, and unincorporated county land follows different rules again.

There is also no state license to look up. Texas does not license residential home builders; the agency that registered them closed in 2009. What the state does license are the trades, plumbers, electricians and air conditioning contractors, so the vetting falls on you. These seven questions are how you do it.

1. How long have you built in my county, and can I see those homes?

Years in business matter less than years in your jurisdiction. A builder who works your city every month knows its plan reviewers, its inspection calendar and the drainage quirks of its neighborhoods.

A good answer names neighborhoods, finished homes and recent dates. Ours: the company was founded in 1992 in Alice, Texas, as Gonzalez Construction by Israel González, and today builds across Hidalgo County, Starr County, Cameron County and Alice. Finished work is on homes we have built.

Ask: “How many homes have you finished in this city or county in the last five years, and can I see two of them?”

2. Who will run my job day to day?

You are not hiring a logo. You are hiring the people who schedule trades, call inspections and decide what happens when something goes wrong on a Tuesday. Get names, not departments.

At South Texas Builders, Javier González, our second generation construction manager, supervises the job sites directly. Ramiro Lerma schedules trades and deliveries, Orlando Peña runs permitting, and Nadia Benavides handles draw requests and lender paperwork. You can meet each of them on our team page.

Ask: “Who is my point of contact, how often will I hear from them, and who is on site when the inspector comes?”

3. What exactly does the price include, in writing?

A price per square foot means nothing until you see the list behind it. Ask whether the contract is a fixed price or cost plus, and ask for two written lists: what is included and what is not.

For comparison, this is how we publish ours. Every home is built to one standard, Fully Loaded, and the rate changes only by region:

Always included: all permits except windstorm where it applies, ten dirt hauls of 14 yards each, open cell spray foam insulation, a windows allocation of 1.5% of the sale price, recessed lighting within the electrical allowance, and free custom blueprints with the purchase of your home. Quoted separately: land, septic, windstorm insurance, appliances, utility connections, extra dirt hauls, awnings, a concrete pump if the site needs one, and driveway beyond the garage allowance. The full breakdown is in our 2026 cost guide and on what is included in every build.

Ask: “Is this a fixed price or cost plus, and can I have the inclusions and exclusions in writing before I sign?”

4. How do allowances and change orders work?

Allowances are the budget the contract sets aside for finishes you have not picked yet: tile, fixtures, countertops, the front door. Choose above the allowance and you pay the difference; choose below it and you should get a credit. A low price with thin allowances is a high price you will meet later, in the showroom.

Ours are published so you can compare them line by line:

Change orders should be written, priced and signed before any work changes. Timing decides the cost: moving a wall on paper costs drawing time, moving it after drywall costs demolition.

Ask: “What are your allowances by category, and what does a change order look like from request to signature?”

5. How will your draws work with my lender?

Most families here build with a construction loan that pays the builder in stages, called draws, as each phase passes inspection. You typically pay interest only on what has been drawn until the home is finished. A builder who submits incomplete draw requests costs you weeks.

We do not lend money, but we work with FHA, VA, USDA, conventional and one time close construction loans, and we can introduce you to Valley lenders who close them regularly. Our financing guidance page shows the draw schedule phase by phase, and our loan comparison explains the programs.

Ask: “Can I see a sample draw schedule, and who on your team submits draw requests to my lender?”

6. Which documents will you give me, and when?

Texas law helps you here. On a residential construction contract, the builder owes you specific paperwork, and the rest is worth asking for:

1. The lien disclosure statement, before you sign. Texas Property Code section 53.255 requires the contractor to deliver a written statement of your rights under the lien laws before you sign a residential construction contract.
2. A final bills paid affidavit, at final payment. Under section 53.259, the contractor must swear that every trade and supplier has been paid in full, or list who is still owed and how much.
3. Proof of insurance and trade licenses. Plumbers are licensed by the Texas State Board of Plumbing Examiners; electricians and air conditioning contractors by the Texas Department of Licensing and Regulation. Both publish license lookups.
4. The warranty, as a document. Not a sentence in a sales conversation: what is covered, for how long, and how you file a claim.
5. Inspection records. Inside city limits, the city inspects foundation, framing, rough ins and final. In Cameron County, add the windstorm inspections and the certificate that follows.

Ask: “Will you give me the lien disclosure statement before I sign, and a bills paid affidavit when I make the final payment?”

7. Can I talk to families you have built for?

Photos show finishes. References show how problems were handled, which is what separates builders once the slab is poured. Ask for recent clients, call two, and ask what went wrong and what the builder did about it. Then walk a finished home and look at the details: tile lines, trim joints, caulk at the tub, how the doors close.

You can hear from families who built with us on client stories, and we are happy to provide references.

Ask: “Can I speak with two families whose homes you finished in the last year?”

What should make you walk away?

• A price per square foot with no written list of exclusions.
• Pressure to sign before you are prequalified with a lender.
• A request to deed your land to the builder. The statutory disclosure itself tells you a contractor may not require you to convey your property as a condition of the contract.
• Any mention of a “Texas builder’s license.” It does not exist.
• Vague answers about who will be on site.
• No written change order process.

Your checklist

1. Experience in my county, with homes I can visit.
2. Named people for site supervision, scheduling, permits and draws.
3. Fixed price or cost plus, with written inclusions and exclusions.
4. Allowances by category and a written change order process.
5. A sample draw schedule that fits my lender.
6. Lien disclosure before signing, a bills paid affidavit at the end, insurance, trade licenses and a written warranty.
7. Two recent references and a finished home to walk.

Take the list to every builder you interview, including us. If you want to hear our answers in person, schedule a consultation and bring your lot details, your budget and any plans you have collected.
