What Every LIHTC Lender Should Know About the AIA Contract

If you are a lender or equity investor closing a LIHTC construction or rehabilitation transaction, the AIA contract is almost certainly sitting in your closing package. You may have a lawyer review it for legal risk. You may have a financial underwriter check the contract sum against the sources and uses. But unless you have a licensed architect reviewing it for construction risk — the kind of risk that affects whether the project actually gets built as proposed — there are provisions in that contract that deserve more attention than they typically receive.

This post explains what the AIA contract actually covers, which provisions matter most to lenders and equity investors on LIHTC transactions, and what a thorough Architectural Document and Cost Review catches that standard legal and financial review misses.

What Is the AIA Contract?

The American Institute of Architects publishes a family of standard contract documents that govern the relationships between owners, contractors, and architects on construction projects. The two most common forms in LIHTC construction and rehabilitation transactions are:

AIA A101 — Standard Form of Agreement Between Owner and Contractor (Stipulated Sum): Used when the contract price is a fixed lump sum. The contractor agrees to complete the defined scope of work for a specific dollar amount regardless of actual costs. This is the most common form in LIHTC new construction.

AIA A102 — Standard Form of Agreement Between Owner and Contractor (Cost Plus with GMP): Used when the contract price is the actual cost of the work plus a fee, subject to a Guaranteed Maximum Price. More common in rehabilitation transactions where the full scope is difficult to define precisely at the outset.

Both forms are used in conjunction with AIA A201 — General Conditions of the Contract for Construction, which is the document that actually defines how the project is administered — how change orders are processed, how disputes are resolved, what the contractor’s obligations are, and what happens when things go wrong. The A201 is often treated as boilerplate. It is not. The A201 is where construction risk actually lives.

Why Lenders and Investors Should Care

The AIA contract is a legal document between the owner and the contractor. As a lender or equity investor, you are not a party to it. But you are directly affected by it.

If the contract sum doesn’t match the Schedule of Values, that’s a discrepancy that affects your loan-to-cost underwriting. If the retainage provisions allow the contractor to reduce retainage below acceptable levels before the project is complete, that’s a risk to your security interest. If the change order provisions give the contractor broad latitude to claim additional compensation for conditions that should have been anticipated, that’s a budget risk that could affect your draw disbursements and ultimately the project’s completion. If the dispute resolution provisions require lengthy arbitration before the owner can terminate a defaulting contractor, that’s a timeline risk that could affect tax credit delivery.

None of those risks are legal risks in the traditional sense. They are construction risks — and identifying them requires someone who understands both the contract language and what it means in the field.

The Provisions That Matter Most

Contract Sum and the Schedule of Values

The contract sum is the number that drives everything downstream — the loan amount, the equity investment, the bond amounts, the payment and performance obligations. The first thing a thorough contract review does is confirm that the contract sum matches the Schedule of Values and that both match the sources and uses in the LIHTC application.

Mismatches between these three documents are more common than they should be. A contract sum that is higher than the SOV total suggests line items that haven’t been fully scoped. A contract sum that is lower than the LIHTC application budget may indicate that the developer has padded the application — or that the contractor has underpriced the work. Either situation warrants investigation before closing.

Retainage

Retainage is the percentage of each draw request that the lender holds back as security against incomplete or defective work. The AIA A101 allows the parties to negotiate retainage terms, and those terms vary significantly from contract to contract.

The industry standard for LIHTC transactions is retainage of 10% dropping to 5% at substantial completion, or straight 5% throughout. What is not acceptable — unless explicitly approved by the applicable state housing finance agency or lender — is retainage that starts at 5% and drops to 0% at project midpoint. That structure eliminates the lender’s leverage over the contractor in the second half of the project, precisely when most construction disputes arise.

A contract review confirms that the retainage provisions meet the applicable lender and agency requirements before the first draw is submitted.

Change Order Provisions

Change orders are how the construction contract evolves over the life of the project. Every change to the scope, schedule, or contract sum requires a change order — and the A201 General Conditions define how those changes are proposed, evaluated, and approved.

The change order provisions that create the most risk for lenders and investors are those that give the contractor broad latitude to claim additional compensation for unforeseen conditions, owner-caused delays, or scope interpretations. A contractor who successfully argues that a condition that should have been visible in the drawings constitutes an unforeseen condition — entitling them to additional compensation — is drawing on a poorly negotiated change order provision. Reviewing the A201 for language that limits the contractor’s ability to make unilateral claims is a meaningful risk management step.

Liquidated Damages

Liquidated damages are the penalty the contractor pays for each day the project runs past the contractual completion date. They exist to incentivize the contractor to maintain schedule — and on LIHTC transactions, schedule is directly tied to credit delivery. A project that misses the placed-in-service deadline risks losing the tax credits that make the deal work.

Liquidated damages provisions that are too low — a few hundred dollars per day on a multi-million dollar project — provide no real incentive. A thorough contract review confirms that the liquidated damages amount is sufficient to actually motivate the contractor to prioritize schedule, and flags provisions that are nominal rather than substantive.

Dispute Resolution

The A201 requires disputes to go through a mandatory initial decision process, followed by mediation, before either party can pursue arbitration or litigation. That process takes time — and on a LIHTC project where credit delivery deadlines are fixed, time is the one thing you cannot afford to lose.

The dispute resolution provisions become most relevant when a contractor defaults or abandons the project. A contract that requires months of mandatory dispute resolution before the owner can terminate and engage a replacement contractor is a significant risk on any transaction. Reviewing the dispute resolution provisions and understanding the termination rights under the contract is a step that many lenders skip and later regret.

Contractor Termination Rights

The A201 gives the owner the right to terminate the contractor for cause under specific conditions — and gives the contractor the right to suspend work or terminate the contract if the owner fails to make timely payment. Those termination rights need to be understood by any lender or investor whose security interest depends on the project being completed.

A contract review confirms that the termination provisions are consistent with the applicable lender requirements, that the contractor’s right to suspend work for nonpayment is appropriately qualified, and that the owner’s termination for convenience provisions don’t create unexpected cost exposure.

What This Means for LIHTC Transactions Specifically

LIHTC transactions add a layer of complexity to the construction contract review that standard commercial transactions don’t have. The tax credit delivery timeline is fixed. The accessibility requirements — UFAS, Fair Housing Act, ADA — are more stringent than standard commercial construction. The regulatory compliance obligations extend well beyond project completion. And the equity investor has an independent interest in the project’s completion that is separate from — and sometimes in tension with — the construction lender’s interest.

A thorough AIA contract review on a LIHTC transaction addresses all of those dimensions. It confirms that the contract sum is consistent with the LIHTC application budget. It verifies that the retainage provisions meet state HFA and lender requirements. It evaluates the change order and dispute resolution provisions for provisions that could create credit delivery risk. And it confirms that the contractor’s scope and obligations are consistent with the accessibility and regulatory requirements of the LIHTC program.

That review is most valuable when it is conducted by someone who understands both the contract language and the LIHTC transaction it is supporting. A lawyer reviewing for legal risk and a financial underwriter reviewing for budget compliance are both necessary — but neither of them is reading the contract through the lens of construction risk and credit delivery. That is what an architect-led Architectural Document and Cost Review provides.

The Bottom Line

The AIA contract is not boilerplate. It is the document that governs what happens when the project goes sideways — and on LIHTC transactions, going sideways has consequences that extend well beyond a construction dispute. Understanding what the contract actually says, and what it means for your position as a lender or equity investor, is a step that deserves the same attention as any other element of the due diligence package.
