New Construction Contract Data
A luxury new construction contract is not a purchase agreement. It is a construction management document that allocates risk between the buyer and the general contractor across a project timeline of 18–36 months, $3M–$15M+ in total cost, and a specification scope that changes 30–60 times before the certificate of occupancy is issued. The standard AIA (American Institute of Architects) A105 or A201 residential construction contract gives the contractor enormous advantages that most luxury buyers have never read: the contractor controls the project schedule; change orders that increase cost require only the contractor’s written notice to be enforceable; the contractor’s right to stop work for non-payment vests immediately while the owner’s right to terminate for default requires a 7–14 day cure period; and the dispute resolution mechanism is binding arbitration that cannot be appealed. Layered on top of the standard AIA structure are the tariff-driven cost escalation clauses, material substitution provisions, and performance bond requirements that have become the most consequential negotiating points in luxury construction since 2025. A buyer who signs a luxury construction contract without having it reviewed by a construction attorney has signed a document written by and for the contractor — and will discover exactly how much it favors the contractor the first time they request a schedule change, dispute a change order, or discover that the “fixed price” contains an uncapped tariff escalation provision.
Luxury new construction contract review — cost structure, change order controls, material substitution rights, performance bond requirements, draw schedule mechanics, certificate of occupancy conditions, and dispute resolution provisions — must occur before the contract is executed.

Contract Clause-by-Clause Analysis
Fixed Price vs. Cost-Plus vs. GMP — The Contract Structure That Determines Risk Allocation. The three primary luxury construction contract structures have materially different risk profiles: Fixed price: the contractor delivers the specified scope at a stated price regardless of actual material and labor costs. Eliminates cost overrun risk for the buyer. In the current tariff environment, most reputable GCs will not offer true fixed-price contracts on imported-material-heavy specifications because they cannot price the tariff risk. Cost-plus: the owner pays actual material and labor costs plus the GC’s fee (typically 10–20% of total cost). Completely eliminates the GC’s cost risk but transfers all cost overrun exposure to the owner. On a $5M construction budget, the owner is exposed to the full upside of any cost increase — including tariff escalation, subcontractor delays, and material substitution cost differentials. Guaranteed Maximum Price (GMP): the contractor delivers the project at cost-plus terms up to a defined maximum, after which the contractor absorbs all additional costs. The GMP structure is the appropriate compromise for luxury construction in the current environment: the owner gets cost certainty above the GMP while benefiting from savings if actual costs come in below the cap. The negotiating mechanic: require a GMP with a 15–20% contingency built into the stated maximum, a detailed specification that defines what is included in the GMP scope (to prevent scope creep disputes), and a savings-sharing provision that returns 50% of any underspend below the GMP to the owner.

Change Orders — The Mechanism That Turns a $5M Project Into a $7M Project. Change orders are written amendments to the construction contract that add, delete, or modify scope and adjust the contract price and schedule accordingly. On a luxury construction project, change orders are not exceptional events — they are the normal operating mechanism of a project. A 12,000 sq ft custom estate will generate 40–80 change orders over a 24-month construction period. The change order risk for owners: under standard AIA contract terms, the contractor issues a change order proposal and the owner has a defined period (typically 7–21 days) to approve or reject it. A rejected change order does not stop the work — the contractor can continue under protest and preserve the right to claim the disputed amount in arbitration. An approved change order increases the contract price immediately and is typically added to the next construction draw. The protective mechanic: negotiate a change order approval process that requires the owner’s written approval before any additional work above a defined threshold ($5,000–$10,000) is commenced, a change order log that the owner’s project manager reviews monthly, and a written procedure for resolving disputed change orders without stopping work. The single most common luxury construction dispute is a contractor who performed “directed work” — additional scope verbally authorized by the owner’s architect or project manager without a signed change order — and claims the cost at project completion.

Draw Schedules — The Payment Mechanics That Protect Both Parties. A construction draw schedule releases payment to the contractor in installments tied to verifiable construction milestones: foundation completion, framing, rough mechanical (plumbing, electrical, HVAC rough-in), insulation and drywall, finish mechanical and cabinetry, and completion. The draw schedule is the owner’s primary financial control over the project — the contractor does not receive payment until the milestone is independently verified. The lender’s inspector (on construction loan projects) or the owner’s project manager (on self-financed projects) verifies milestone completion before each draw is released. The front-loading trap: a contractor who negotiates a draw schedule that pays 30–40% of the contract at contract execution and “mobilization” has front-loaded the payment structure in a way that reduces the owner’s leverage throughout the project. The correct draw schedule for a luxury construction project: no more than 10% at contract execution (mobilization), milestone-based releases of 10–15% each, a 10% retainage held through substantial completion, and the final retainage release conditioned on the certificate of occupancy and punch list completion. Retainage — the percentage of each draw withheld until project completion — is the owner’s most powerful completion incentive.
Lien Releases — The Subcontractor Payment Documentation That Protects Title. Mechanic’s liens from unpaid subcontractors and material suppliers are the most common title problem in new construction luxury real estate. A subcontractor who performed $200,000 of plumbing work on a $6M custom home and was not paid by the general contractor can file a mechanic’s lien against the property — even if the owner paid the GC in full and had no knowledge of the non-payment. The protective mechanic: require the GC to deliver unconditional lien releases from every subcontractor and material supplier — covering all work through the date of the draw — as a condition of each draw payment. On a $6M project with 20 subcontractors, the lien release package for each draw may include 20–25 documents. A construction draw released without lien releases from all active subcontractors is a draw that may fund a future title cloud. The certificate of occupancy closing: the final payment and retainage release should be conditioned on: (1) certificate of occupancy issued by the local building department, (2) unconditional final lien releases from all subcontractors and material suppliers, (3) completed punch list, and (4) as-built drawings and all equipment manuals delivered.
Performance and Payment Bonds — GC Default Protection in the Tariff Era. A performance bond is a surety guarantee that the GC will complete the project according to contract terms. A payment bond guarantees that all subcontractors and material suppliers will be paid. In the current tariff environment where GCs are absorbing losses on pre-tariff fixed-price contracts, GC financial distress and mid-project abandonment risk is materially higher than in prior cycles. A GC who signed a $6M fixed-price contract in 2023 at pre-tariff material costs and is executing it at $7.5M in actual 2026 costs is absorbing $1.5M in losses — a financial stress level that creates real default risk on an actively ongoing project. The bond cost: a combined payment and performance bond costs 1–1.5% of contract value — $60,000–$90,000 on a $6M contract. A GC who refuses to provide a performance bond is signaling that their surety has assessed their financial condition as too risky to guarantee. Treat a GC’s refusal to bond a luxury project as a disqualifying condition, not a negotiating point. Texas Verified Specialists →
Certificate of Occupancy — The Condition Precedent That Protects the Buyer. The certificate of occupancy (CO) is the local building department’s formal approval that the structure was built in accordance with the approved plans and applicable building codes. No CO means the structure is not legally habitable — the buyer cannot occupy it, the lender will not release the final construction draw, and title insurance cannot be issued for a completed residential structure without a CO. The CO contingency in a luxury new construction purchase: the buyer’s obligation to close the permanent mortgage (converting the construction loan to a term loan) and the seller/builder’s obligation to deliver title should both be conditioned on the CO being issued by the building department. The most common new construction closing failure: the GC declares the property substantially complete, requests the final draw, and the owner closes — only to discover that the building department’s final inspection identified code deficiencies that prevented CO issuance. The owner now occupies a property without a CO, which creates insurance, financing, and title insurance complications. The correct protocol: CO issued before final draw, before occupancy, and before title transfer on a new construction sale.
The Bottom Line
A luxury new construction contract is the most consequential document a buyer signs in a real estate transaction — more consequential than the purchase agreement for an existing home because it governs a 24–36 month relationship during which $5M–$15M+ of capital is committed and deployed before the buyer takes title. The cost structure, change order controls, draw schedule, lien release requirements, performance bond, and CO contingency are all negotiable before execution — and entirely the buyer’s problem after execution.
FAQ
What is a Guaranteed Maximum Price contract and why is it better than fixed-price in 2026?
A GMP contract delivers the project at cost-plus terms up to a defined maximum, after which the contractor absorbs all additional costs. In the current tariff environment most reputable GCs will not offer true fixed-price contracts because they cannot price tariff risk on imported materials. The GMP provides cost certainty above the cap while benefiting from savings below it. Negotiate a 15 to 20 percent contingency built into the GMP, a defined specification scope, and a 50 percent savings-sharing provision for underspend.
How do change orders turn a $5M luxury construction project into a $7M project?
Change orders add, delete, or modify scope and adjust the contract price. A 12,000 sq ft custom estate generates 40 to 80 change orders over 24 months. Under standard AIA terms the contractor can continue work under a disputed change order and claim the cost in arbitration. The protective mechanic: require written owner approval before any additional work above $5,000 to $10,000 is commenced, a monthly change order log review, and a written dispute resolution procedure that does not stop work.
What are lien releases and why must they accompany every construction draw?
Lien releases are signed documents from subcontractors and material suppliers confirming they have been paid for all work through the draw date and waiving their right to file a mechanic's lien against the property for that work. A mechanic's lien from an unpaid subcontractor attaches to the property even if the owner paid the GC in full. Requiring unconditional lien releases from all active subcontractors as a condition of each draw payment prevents title clouds from accumulating during construction.
What does a performance bond cost and when is a GC's refusal to provide one a red flag?
A combined payment and performance bond costs 1 to 1.5 percent of contract value, or $60,000 to $90,000 on a $6M luxury construction contract. In the current tariff environment where GCs may be absorbing losses on pre-tariff fixed-price contracts, a GC who refuses to provide a performance bond is signaling their surety has assessed their financial condition as too risky to guarantee. Treat this as a disqualifying condition rather than a negotiating point.
Luxury new construction contract review — cost structure, GMP negotiation, change order controls, lien release requirements, performance bond, draw schedule structure, and CO contingency — must occur before the contract is executed.

“A buyer who signs a $7M luxury construction contract with an uncapped tariff escalation clause, a 35% upfront mobilization payment, no performance bond requirement, and no written change order approval threshold has signed a contract that the GC’s attorney wrote and the buyer’s attorney did not review. Twelve months in, the project is $1.4M over budget from tariff escalation and approved change orders, the GC is financially stressed, and the buyer has no performance bond to call. All of that was negotiable at contract execution. None of it is negotiable in month 12. The specialist we verify for new construction luxury transactions has connected the buyer with a construction attorney before the AIA contract is reviewed — not after the first change order dispute. That is what the 5% Performance Audit™ confirms before we make one introduction.”
