Signing a custom home builder’s contract in Texas is one of the most significant financial and legal commitments a Houston homeowner will ever make. The average custom home in Houston costs between $500,000 and $1.5 million or more. Yet most homeowners spend more time negotiating their car purchase than they spend reading and understanding the construction contract that governs that investment.
This guide breaks down what a Texas custom home contract actually says, what every clause means for you as the homeowner, and the specific red flags that should send you back to the negotiating table or away from that builder entirely.
Why the Builder’s Contract Is the Most Important Document in Your Entire Project
Unlike a purchase agreement for an existing home, which is relatively standardized in Texas, a custom home construction contract is almost always written by or for the builder. That means its default terms protect the builder’s interests, not yours. Texas law gives builders substantial latitude in how they structure these agreements, and there is no mandatory state form.
Everything that happens on your project, including how cost overruns are handled, who owns design drawings, what triggers a delay, how disputes are resolved, and whether you can fire the builder if things go wrong, is defined in this document. Understanding it before you sign is not optional. You can learn more about how we build and what sets us apart on our services page.
The Core Sections of a Texas Custom Home Builder Contract
1. Parties and Project Description
The contract must clearly identify the full legal names of both parties, you as the homeowner and the builder’s legal entity (not just their trade name). It should include the Texas contractor license number, the physical address of the construction site, and a reference to the project documents (plans, specifications, and drawings) that form part of the agreement.
Red flag: A contract that references “plans to be determined” or “specifications attached later” without attaching them is signing a blank check. Never execute a contract without completed drawings attached as exhibits.
2. Contract Price and Payment Schedule
The contract should state the total contract price, whether it is a fixed-price (lump sum) agreement or a cost-plus arrangement, and a detailed draw schedule. In Texas, most custom home contracts use a percentage-based draw schedule tied to construction milestones: foundation, frame completion, dry-in, mechanical rough-in, insulation, drywall, finish-out, and final completion.
Healthy Payment Schedule Milestones
- Foundation completion: typically 10 to 15 percent of contract price
- Framing complete: typically 15 to 20 percent
- Dry-in (roof, windows, exterior doors): typically 10 to 15 percent
- Mechanical rough-in (plumbing, electrical, HVAC): typically 10 to 15 percent
- Insulation and drywall: typically 10 percent
- Finish-out and cabinetry: typically 15 to 20 percent
- Final completion and certificate of occupancy: 10 percent retainage minimum
Red flag: Any contract that front-loads payments, requesting 30 to 40 percent before foundation is poured, is a serious warning sign. This is a pattern associated with undercapitalized or fraudulent builders in Texas.
3. Allowances vs. Fixed Specifications
Allowances are budget placeholders for items not yet specified: a flooring allowance of $8 per square foot, a fixture allowance of $1,500 per bathroom, a countertop allowance of $60 per square foot. Allowances are one of the most common sources of budget overruns in Houston custom homes because homeowners routinely exceed them.
A well-structured contract minimizes allowances by specifying actual selections at the time of signing. The more decisions are specified, including material brand, model number, color, and grade, the more accurate your contract price will be. Demand a selection meeting before signing whenever possible.
Red flag: A contract with more than 15 to 20 percent of its total value in allowances is underspecified. The builder may be using low allowances to win the bid, knowing real costs will be higher.
4. Change Order Procedures
Every change to the scope, materials, or specifications after contract execution must be captured in a written change order signed by both parties before work begins. The change order should state the added or reduced scope, the cost impact, and the schedule impact. No reputable Texas builder should perform changed work without a signed change order in advance.
Red flag: Any verbal agreement to make a change is unenforceable. Get every modification in writing before work proceeds. This protects both parties.
5. Completion Date and Delay Clauses
The contract should state a target substantial completion date. It should also define what constitutes an excused delay (weather, material shortages, force majeure) versus an unexcused delay, and what the builder owes you for unexcused delays. Liquidated damages clauses, which specify a dollar amount per day of delay owed to the homeowner, are negotiable in Texas and are worth requesting on large projects.
6. Texas Lien Law Provisions: Critical Protection
Texas has strong mechanic’s lien laws, and they can place your home at risk even when you have paid the general contractor in full. Under Texas Property Code Section 53.254, a construction contract on a homestead must be in writing and executed before any work begins, or no lien can be fixed on the property. Your contract should include provisions for: conditional and unconditional lien waivers from the contractor and all major subcontractors at each draw; a requirement that the contractor pay all subcontractors and suppliers from draw proceeds; and your right to pay subcontractors directly if the general contractor fails to do so. You can read the full statutory text at Texas Property Code Section 53.254.
Texas Lien Law Protections to Require in Your Contract
- Conditional lien waiver from GC and all subs with each draw payment
- Unconditional lien waiver from GC and all subs upon final payment
- Monthly subcontractor payment certifications
- GC obligation to pay all subs within 7 days of receiving homeowner draw payment
- Homeowner right of direct payment to protect against GC default
- Sworn statement of subs and suppliers prior to each draw
7. Warranty Provisions
Under Texas law (Chapter 430 of the Property Code), residential contractors must provide mandatory warranties: 1 year on workmanship and materials, 2 years on plumbing, electrical, HVAC, and mechanical systems, and 10 years on major structural components. Your contract should explicitly state these minimums. Under a 2023 legislative change (HB 2024), a builder who provides a written warranty covering at least these periods may qualify for a 6-year statute of repose instead of 10 years, which is worth understanding when negotiating warranty terms. Ask your builder whether they offer any enhancements above the statutory minimums.
8. Dispute Resolution: Arbitration vs. Litigation
Most Houston builder contracts include a mandatory arbitration clause. Arbitration can resolve disputes faster and more privately than litigation, but it limits your appellate rights and can favor repeat-player builders who are familiar with specific arbitrators. Before signing an arbitration clause, understand: which arbitration rules apply (AAA, JAMS, or other), who selects the arbitrator, how fees are allocated, and whether the decision is final and binding.

Frequently Asked Questions
Does Texas law require a written contract for custom home construction?
Texas law does not require a written contract for all residential construction, but any project over a minimal dollar threshold should always have a comprehensive written agreement. For homestead properties, Texas Property Code Section 53.254 requires the construction contract to be in writing and executed before work begins in order for any lien to attach to the property. Without a written contract, disputes over scope, price, and timeline become he-said/she-said disagreements that are difficult and expensive to resolve.
Should I hire a real estate attorney to review my builder contract in Texas?
Yes. For a custom home project in Houston involving hundreds of thousands of dollars, a Texas real estate or construction attorney’s review fee of $500 to $2,000 is among the best money you will spend. An attorney familiar with Texas construction law can identify unenforceable clauses, negotiate better terms, and add protective provisions you would not know to request.
What is the difference between a fixed-price and cost-plus contract?
A fixed-price (lump sum) contract gives you a known total cost for a defined scope. A cost-plus contract reimburses the builder for actual costs plus a fee or percentage. Fixed-price provides budget certainty; cost-plus can be appropriate when the scope is genuinely incomplete at signing, but requires more trust in the builder’s cost management and complete access to actual cost documentation.
Can I negotiate a Texas custom home builder’s contract?
Yes. Builder contracts are negotiable, particularly on larger projects. Common successful negotiation points include: higher retainage percentage (10 to 15 percent), lower allowance amounts with more selections specified, liquidated damages for unexcused delays, enhanced lien waiver requirements, and extended warranty terms above Texas statutory minimums.
What happens if my builder in Texas goes out of business mid-project?
Your ability to recover depends entirely on what is in your contract. Protective provisions include: a construction escrow or trust account for draw funds, a completion bond or payment and performance bond, strong lien waiver requirements, and clear contract default and termination rights. Without these, your recourse is expensive and uncertain.
