Covers mechanics liens, payment bonds, and stop notices as payment protection mechanisms in construction, including lien filing requirements, conditional and unconditional lien waivers, payment bond claims on public projects, A201 Section 9.3 payment applications, retainage, and the architect's role in certifying payment to protect against lien exposure.

Overview

Construction projects involve complex payment chains. The owner pays the contractor, the contractor pays subcontractors, and subcontractors pay their suppliers. When someone in this chain does not get paid, the law provides several remedies to protect their right to compensation.

A mechanics lien is a legal claim placed on the owner's property by an unpaid contractor, subcontractor, or supplier. The lien gives the claimant a security interest in the real property where the work was performed. If the lien is not resolved, the claimant can foreclose on the property to recover payment. Mechanics liens are available on private projects but generally not on public projects because government property cannot be liened.

On public projects, payment bonds serve the same protective function. The contractor obtains a payment bond from a surety company, guaranteeing that subcontractors and suppliers will be paid. If the contractor fails to pay, the unpaid party can make a claim against the payment bond.

A stop notice is a written demand served on the owner or lender directing them to withhold construction funds sufficient to cover the claimant's unpaid amount. Stop notices provide a mechanism for subcontractors and suppliers to reach funds held by the owner before those funds are paid to the contractor.

The architect's role in this payment protection framework centers on A201 Section 9.3 and the certification of payment applications. By reviewing and certifying the contractor's applications for payment, the architect helps ensure that the payment chain functions properly and that the owner is protected from lien exposure. The architect may withhold certification if there is evidence that the contractor is not paying subcontractors, which is one of the seven grounds for withholding under A201 Section 9.5.1.

Mechanics Lien Fundamentals Mechanics lien laws vary by state, but the general framework is consistent. Anyone who provides labor, materials, or services that improve real property has the right to file a lien if they are not paid. The lien attaches to the property itself, not to the person who failed to pay. Filing requirements typically include a preliminary notice (sent before work begins, required in many states to preserve lien rights), a deadline for filing the lien (usually within a specified number of days after the last date of work, typically 60-90 days), a requirement that the lien be filed with the county recorder's office, and a deadline for enforcing the lien through foreclosure (typically 6-12 months after filing). Missing any of these deadlines can extinguish lien rights. Lien Waivers Lien waivers are documents signed by contractors, subcontractors, and suppliers releasing their lien rights in exchange for payment.

Lien Waiver Administration Architects should establish a lien waiver protocol at the start of construction. The protocol should specify which lien waivers are required with each payment application (typically conditional waivers for the current payment and unconditional waivers for the previous payment), the format and statutory requirements for waivers in the project jurisdiction, and the process for collecting waivers from the general contractor for subcontractor and supplier tiers. Many jurisdictions have statutory lien waiver forms that must be used. Using non-statutory forms may render the waivers unenforceable. The architect should confirm that the correct forms are being used for the project jurisdiction. Recognizing Payment Chain Problems The architect is not an accountant and does not audit the contractor's books. However, the architect should be alert to signs that the payment chain is breaking down.

TLDR

Mechanics liens: legal claims on property by unpaid contractors/subs/suppliers -- available on private projects only. Must file preliminary notice, file lien within deadline (60-90 days after last work), enforce within 6-12 months. Payment bonds: required on public projects (Miller Act federal, Little Miller Act state). Subcontractors claim against the bond if unpaid. Stop notices: written demand to owner/lender to withhold funds. Lien waivers: four types (conditional/unconditional x progress/final) -- collect with every pay application. A201 Section 9.3: contractor submits pay apps using G702/G703, architect certifies. Section 9.5.1: architect can withhold certification if contractor is not paying subs. Retainage: 5-10% withheld until substantial completion. Monitor for warning signs: subcontractor complaints, late waivers, preliminary notices.

Imagine you hire a general contractor to renovate your kitchen. The contractor hires a plumber. You pay the contractor, but the contractor does not pay the plumber. The plumber is upset -- they did the work but got nothing. A mechanics lien is the plumber's way of saying, "I improved this property, and I deserve to be paid." The plumber files a legal document that attaches to your house. If the bill is not paid, the plumber can eventually force the sale of the house to get the money. This puts pressure on you (the owner) to make sure the contractor pays the plumber -- even though you already paid the contractor. To protect yourself, you should collect lien waivers with every payment. A lien waiver is the plumber's signed statement: "I got paid for this work, so I will not file a lien.
