How Payment Works in Construction Projects
What Payment in Construction Means
Payment in construction is how money moves from the property owner (or their lender) to the contractor, subcontractors, and suppliers who build the project. Unlike a single bill you pay once, construction payments happen in stages as work gets completed. The owner doesn't pay for the entire building upfront—they pay as walls go up, electrical work finishes, or materials arrive on site.
The timing and method of these payments depend on the contract type, the project size, and whether a bank is financing the work. A small kitchen remodel might use one payment at the end. A new house or commercial building typically uses five to ten payments spread across months or years. Understanding how this works protects you whether you're the owner writing checks, a contractor waiting to get paid, or a supplier trying to collect what you're owed.
Key Takeaways
- Construction payments happen in stages tied to completed work, not all at once, and the contract spells out when each payment is due.
- A lender (bank or mortgage company) often controls the money and releases it only after an inspector confirms work is done correctly.
- Contractors and subcontractors may wait weeks or months to get paid because payments flow down a chain from owner to general contractor to subs.
- Mechanics liens and stop-work notices are legal tools suppliers and workers use when payment is late or missing.
- Payment disputes in construction often end up in court or arbitration because the amounts are large and the work is permanent.
How Payment Stages Work in Construction Contracts
A construction contract lays out a payment schedule before work starts. The schedule lists what percentage of the total price is due at each milestone—for example, 20% when the foundation is poured, 30% when framing is complete, 25% when the roof is on, and 25% at final completion. These percentages and milestones vary widely depending on the project type and what the owner and contractor agree to.
The contractor submits a payment request (often called a draw request or progress invoice) when a stage is finished. This document describes what work was done, includes photos or inspection reports, and asks for the money owed at that stage. The owner or their representative reviews it, confirms the work matches the contract, and approves payment. If work is incomplete or doesn't meet the contract standard, the payment can be held or reduced until it's fixed.
The time between submitting a draw request and receiving payment is usually 7 to 30 days, depending on the contract terms and how fast the owner processes paperwork. On large projects with a lender involved, the timeline stretches because the lender's inspector must also approve the work before releasing funds.
When a Bank or Lender Controls the Money
On mortgaged or financed construction projects, the lender holds the funds in an escrow account and releases them only after their own inspector verifies that work was completed to code and matches the contract. This protects the lender's investment—they don't want to fund shoddy work or pay for materials that were never delivered.
The process works like this: the contractor completes a stage of work, submits a draw request with photos and documentation, the owner requests a lender inspection, the lender's inspector visits the site and writes a report, and only then does the lender release that portion of the loan to the owner's account. The owner then pays the contractor. This adds 1 to 3 weeks to each payment cycle.
If the lender's inspector finds problems—framing that doesn't meet code, electrical work that's incomplete, materials that don't match the contract—they can withhold payment until it's corrected. This is a common source of delay and frustration, but it's also why lender-backed projects tend to have fewer disputes later: the work was inspected and approved as it went.
The Payment Chain: Owner to Contractor to Subcontractors
Money in construction flows downward through a chain. The owner pays the general contractor (or prime contractor), who then pays the subcontractors (electricians, plumbers, framers, etc.), who in turn pay their suppliers and workers. Each step in the chain takes time, and delays at any point ripple downward.
A subcontractor might finish their work in week 3, but not get paid until week 6 or later because the general contractor waits for the owner's payment, then processes invoices, then cuts checks. On large projects, this delay can stretch to months. Subcontractors and suppliers often have to cover their own costs—materials, labor, equipment—while waiting for payment to arrive.
Some contracts include a retainage clause, which means the owner holds back a percentage (often 5% to 10%) of each payment until the entire project is finished. This protects the owner against incomplete work or defects, but it means contractors and subs don't see their full payment until the very end—sometimes months after they finish their portion of the work.
What Happens When Payment Is Late or Doesn't Come
Construction law gives suppliers and workers legal tools when payment is overdue. A mechanics lien (also called a construction lien) is a claim against the property itself that says "I did work here or supplied materials here, I wasn't paid, and I have a right to be paid from the sale or refinance of this property." Filing a lien doesn't stop the project, but it clouds the title and makes it hard for the owner to sell or refinance until the lien is resolved.
A stop-work notice is a formal letter stating that work will halt until payment is received. Some states allow contractors to actually stop work; others require a waiting period or court order first. The threat of a stop-work notice often motivates payment because delays cost the owner money and can breach their own contracts with buyers or tenants.
If payment disputes can't be resolved between the parties, they often go to arbitration or court. Construction disputes are expensive to litigate because the amounts are large, the contracts are complex, and expert witnesses (engineers, inspectors, contractors) are needed to testify about what was owed and whether work met the standard. Many construction contracts include an arbitration clause to avoid court, but arbitration still costs thousands in fees and attorney time.
Payment Methods and How Money Actually Moves
Construction payments are usually made by check or ACH transfer (electronic bank-to-bank transfer). Large projects sometimes use a construction loan disbursement, where the lender transfers funds directly to the owner's account or to a title company's escrow account, and the owner then pays the contractor from there.
Checks are common because they create a paper trail and allow the payer to stop payment if a dispute arises. ACH transfers are faster and cheaper but require the contractor to provide banking information and trust the payer to send the funds on the promised date. Some owners require contractors to invoice through a specific system or portal, which adds another layer of processing time.
Payment terms are negotiated in the contract. A contractor might ask for payment within 7 days of submitting a draw request; the owner might counter with 30 days. State law sometimes sets a minimum—for example, some states require payment within 7 to 10 days of the lender's approval. If the contract doesn't specify, state law fills in the gap, but relying on state law is slower and more contentious than having clear terms in writing.
Retainage and Final Payment
Retainage is money the owner holds back from each progress payment, usually 5% to 10% of the draw amount. The idea is to ensure the contractor finishes the job and fixes any defects before getting the final payment. On a $100,000 project with 10% retainage, the contractor might receive $90,000 at each stage and wait until the end to collect the remaining $10,000.
Final payment is due when the project is substantially complete—meaning all work is done, inspections have passed, and any punch-list items (small fixes or touch-ups) are finished. The owner may require a final inspection, a certificate of occupancy from the city, or proof that all subcontractors and suppliers have been paid before releasing the retainage. This final stage can take weeks or months if disputes arise over what counts as "complete."
Some states have laws limiting retainage or requiring it to be released faster once work is substantially done. A few states prohibit retainage altogether on residential projects. Check your state's construction payment laws if retainage is a concern—they may protect you or require the owner to follow specific rules.
Frequently Asked Questions
Can a contractor refuse to start work until a deposit is paid?
Yes. Most contractors ask for a deposit (often 10% to 50% of the total price) before ordering materials or scheduling labor. This protects them against owners who cancel or fail to pay. The deposit is usually credited toward the first payment. State law sometimes limits how much a contractor can ask for upfront, especially on residential projects, so check your state's rules if the deposit seems high.
What if the owner's lender won't approve a draw request?
The contractor can ask the lender in writing why it was denied and what needs to change. If the lender says work doesn't meet code or the contract, the contractor must fix it before resubmitting. If the lender is being unreasonable, the contractor may have a claim against the owner for breach of contract, but proving that in court is expensive and time-consuming. This is why clear communication between the owner, lender, and contractor early in the project prevents disputes later.
How long can an owner legally hold retainage?
State law varies. Some states require retainage to be released within 30 to 45 days of substantial completion; others allow the owner to hold it longer if work isn't finished or defects exist. Your contract should specify the retainage percentage and the release date. If it doesn't, your state's construction payment law applies. Ask your contractor or a local attorney what your state requires.
What does it mean if a mechanics lien is filed against my property?
It means someone (a contractor, subcontractor, or supplier) claims they did work or supplied materials on your property and weren't paid. The lien is a legal claim against the property that must be resolved before you can sell or refinance. You can dispute the lien in court, negotiate a settlement, or pay what's owed. Ignoring a lien doesn't make it go away—it stays on the title until it's formally released or a court removes it.
Can I withhold payment if I'm not happy with the work?
You can withhold payment if the work doesn't meet the contract standard or isn't complete, but you must document why and give the contractor a chance to fix it. Withholding payment without a legitimate reason can expose you to a mechanics lien or a lawsuit for breach of contract. The contract should spell out what happens if work is defective—usually the contractor has a set time to fix it before you withhold payment. If you disagree about whether work is defective, that's a dispute that may need arbitration or court to resolve.
