Construction lending is not just about approving a budget and releasing funds. For SBA and USDA lenders, every draw request creates a moment of risk: Has the work been completed? Have subcontractors and suppliers been paid? Is retainage being tracked correctly? Are lien waivers current, accurate, and tied to the right pay period?
These questions matter because SBA and USDA construction projects often involve layered requirements, tight budgets, multiple contractors, and federal guarantee considerations. SBA’s 7(a) program allows most loans up to $5 million, with guarantees up to 75% for loans above $150,000 and up to 85% for loans of $150,000 or less. USDA’s FY 2026 OneRD notice lists an 85% guarantee for Business & Industry loans under $5 million and 80% for B&I loans from $5 million to $25 million.
Those guarantees help reduce exposure, but they do not remove construction risk. If draws are advanced without proper lien waiver tracking, retainage controls, and payment documentation, the lender may still face collateral issues, project delays, borrower disputes, or guarantee complications.
Why Lien Waivers Matter to Lenders
Lien waivers are simple documents with major consequences. In construction, a waiver is generally an agreement by a contractor, subcontractor, or supplier to waive lien rights in exchange for payment. AIA Contract Documents notes that lenders may require confirmation that no liens have been claimed before funding a draw, and that waivers help confirm payment was made or received through a given date.
For lenders, the issue is not just whether a lien waiver exists. It is whether the waiver matches the draw.
A strong draw package should answer:
- Does the waiver cover the correct project, borrower, contractor, and through date?
- Does the dollar amount reconcile with the pay application?
- Is the waiver conditional or unconditional?
- Does it exclude unpaid retainage, pending change orders, or disputed work?
- Does it comply with state-specific form requirements?
The risk is especially important for lenders working nationally. Lien waiver rules, language, and requirements can vary by state. Some states require specific waiver forms or statutory language, while others leave more flexibility to the contract, payment process, and lender documentation standards. That means lenders should avoid treating lien waivers as a generic formality. The waiver process should be state-aware, draw-specific, and tied directly to each pay application. AIA Contract Documents also recognizes the four primary waiver categories: conditional progress, unconditional progress, conditional final, and unconditional final.
That means a generic lien waiver process may not be enough. SBA and USDA construction lenders need a repeatable, state-aware process that tracks waivers by draw, by party, and by scope of work.
Conditional vs. Unconditional Waivers
Most lien waiver workflows involve four basic categories: conditional waivers on progress payment, unconditional waivers on progress payment, conditional waivers on final payment, and unconditional waivers on final payment. AIA describes these four categories and explains that conditional waivers generally do not relinquish rights until payment is received, while unconditional waivers generally relinquish rights upon execution under the terms of the waiver.
For SBA and USDA construction lenders, the best-practice workflow is to collect conditional waivers with each pay application, confirm or collect unconditional waivers for prior payments once funds have cleared, and require final unconditional waivers at the end of the project before final retainage is released. This keeps waiver collection tied to the actual payment cycle instead of treating it as a last-minute closeout item.
This distinction is critical for draw control.
A conditional progress waiver may be appropriate when payment is about to be made from the current draw. An unconditional progress waiver should generally reflect that the party has already been paid for the covered work. At final payment, the documentation burden increases because retainage, unresolved claims, punch-list work, change orders, and final releases all need to line up.
For lenders, the safest process is one that connects waiver collection to the actual disbursement sequence. Waivers should not float separately from pay applications, inspection reports, retainage ledgers, and disbursement records. They should be part of the same audit trail.
Retainage Is a Control, Not a Footnote
Retainage is often treated as an accounting detail, but it is one of the lender’s most important project controls. When used correctly, retainage helps preserve leverage until work is complete, punch-list items are resolved, closeout documents are delivered, and final lien releases are collected.
Retainage should not be treated as a fixed 10% rule. While 10% may be a lender preference or a common underwriting target, allowable retainage can vary by state, project type, contract terms, and whether the project is public, private, or federally influenced. Many states limit retainage, provide guidance for lower percentages, require reductions at certain completion milestones, or set rules for release timing. Other states may leave more room for negotiation through the contract. For lenders, the key is not simply choosing a percentage – it is confirming that the retainage structure is allowable, documented, and consistently tracked throughout the project. ConsensusDocs notes that retainage rates commonly range from 5% to 10%, but timing, reductions, and requirements vary by state and contract.
USDA’s OneRD construction monitoring rule also highlights the importance of retainage clarity. For certain projects where a loan note guarantee is requested before construction completion, USDA requires evidence of a firm, fixed-price construction contract with detailed costs and terms specifying change order approvals, the agreed retainage percentage, and the disbursement schedule.
For lenders, the takeaway is clear: retainage should be reviewed for state-specific requirements before closing, defined clearly in the contract, tracked during every draw, and released only when waiver, inspection, closeout, and contract requirements support it.
Where Retainage Risk Shows Up
Retainage problems usually appear in one of five places. First, the contract may not clearly define the retainage percentage, release milestones, or treatment of subcontractor retainage. Second, the retainage percentage may not align with state-specific limits, guidance, or project requirements. Third, pay applications may calculate retainage inconsistently across the schedule of values. Fourth, change orders may be approved without updating the retainage ledger. Fifth, final retainage may be released before final unconditional lien waivers, closeout documents, certificates, and inspections are complete.
These issues become more serious in today’s construction environment. Construction input prices were up 40.5% from February 2020 levels as of January 2025, according to Engineering News-Record’s reporting on Bureau of Labor Statistics data. When budgets are under pressure, subcontractor payment timing, stored materials, scope gaps, and retainage disputes can create real stress on project completion.
SBA and USDA Lenders Need a Draw-Level Control System
A draw request should never be evaluated in isolation. It should be reviewed against the contract, budget, schedule of values, inspection report, prior disbursements, lien waivers, retainage ledger, change order log, and remaining funds to complete.
For USDA guaranteed loans, this concept is built directly into the monitoring framework. USDA requires lenders or their designated agents to monitor construction progress and undertake reviews and inspections necessary to confirm that construction conforms to applicable codes, plans, specifications, and contract documents. USDA also requires certain monthly construction reports to include draw certifications, invoices, funds disbursed to date, construction status, inspection reports, and concerns such as potential problems or cost overruns.
A disciplined draw control system should include:
- A pre-closing review of the budget, contract, state-specific waiver and retainage requirements, retainage terms, and disbursement schedule.
- A draw checklist that requires current conditional waivers, prior unconditional waivers once payments have cleared, invoices, inspection support, and retainage calculations.
- A waiver log that tracks every contractor, subcontractor, supplier, waiver type, through date, payment amount, and exception.
- A retainage ledger that reconciles with the schedule of values, contract requirements, applicable state guidance, approved change orders, and remaining funds to complete.
- A closeout process that verifies final unconditional waivers, final inspections, completion documents, and remaining funds before retainage release.
How Independent Funds Control Helps
Independent funds control gives lenders a stronger way to manage the moving parts. A funds control partner can review each draw request, compare the request against verified progress, track lien waivers, monitor retainage, reconcile change orders, flag missing documents, and help ensure funds are disbursed for eligible project costs.
This matters for both credit risk and compliance. USDA regulations specifically allow the lender to rely on written materials and reports from an independent engineer and other qualified consultants when complying with project monitoring requirements. For lenders managing multiple SBA or USDA construction loans, that independent review can help create consistency across projects, regions, borrowers, and contractor teams.
Protecting Lender Funds Starts Before the First Draw
Lien waivers and retainage are not just closeout concerns. They should be built into the loan file before construction begins.
The strongest lenders define expectations early, require consistent documentation, verify progress before payment, and keep every draw tied to a clear audit trail. In an SBA or USDA construction project, that discipline protects more than the current disbursement. It protects the lender’s collateral position, the borrower’s project, and the performance of the loan.
