Construction Subcontract Agreement: Payment, Liability And Termination Terms To Check

Whether you are a general contractor or a subcontractor, signing a construction subcontract agreement is a major step in any US building project. These contracts define the scope of work, payment details, risk allocation, and what happens if things go wrong. Yet, many business owners overlook important terms, misunderstand their legal obligations, or fail to account for state-specific rules. This guide explains what to look for in a construction subcontract agreement, highlights common mistakes, and provides practical examples and checklists to help you protect your business before you sign.

What Is a Construction Subcontract Agreement?

A construction subcontract agreement is a legally binding contract between a general contractor (sometimes called the prime contractor) and a subcontractor. The general contractor is hired by the property owner to manage the entire construction project, while the subcontractor is brought in to perform a specific trade or portion of the work, such as electrical, HVAC, drywall, or roofing.

These agreements are essential for clarifying expectations and responsibilities. They typically include:

• Scope of Work: A detailed description of the tasks the subcontractor is responsible for, including plans, specifications, and standards.
• Schedule: Start and completion dates, milestones, and deadlines for deliverables.
• Payment Terms: How much and when the subcontractor will be paid.
• Quality and Safety Standards: Requirements for workmanship and compliance with building codes and safety regulations.
• Insurance and Licensing: Proof of appropriate insurance and compliance with state contractor licensing laws.
• Change Order Procedures: How changes to the work or price are handled.
• Termination and Dispute Resolution: The process for ending the contract or resolving disagreements.

In many states, both contractors and subcontractors must be properly licensed for the type of work they perform. State contractor licensing boards set the rules, and unlicensed work can lead to fines, criminal penalties, or loss of payment rights. For example, in California, unlicensed subcontractors cannot enforce payment in court, even if the work was completed. Always verify licensing before signing.

Example: A general contractor in Texas hires a painting subcontractor. The subcontract agreement specifies the number of coats, paint brands, and completion dates. If the subcontractor uses a cheaper paint or misses the deadline, the contract provides a basis for resolving the issue.

Key Payment Terms in Construction Subcontract Agreements

Payment disputes are one of the most common sources of conflict in construction. A clear subcontract agreement should address:

• Contract Price: Is the payment a lump sum, unit price, or cost-plus arrangement?
• Payment Schedule: Are payments made monthly, upon reaching milestones, or after final inspection?
• Retainage: Is a percentage of payment withheld until the project is complete and approved?
• Change Orders: How are additional work or modifications priced and approved?
• Pay-When-Paid vs. Pay-If-Paid: Does the subcontractor get paid only after the contractor is paid by the owner (pay-if-paid), or is payment simply delayed until the contractor is paid (pay-when-paid)?
• Mechanic's Lien Rights: Does the contract preserve or waive the subcontractor's right to file a lien if unpaid?

Federal baseline: There is no federal law governing payment timing for private construction projects; payment terms are set by contract and state law. Most states have prompt payment statutes requiring contractors to pay subcontractors within a certain time after receiving payment from the owner. For example, New York requires payment within seven days, while Texas allows up to 35 days.

Pay-if-paid clauses: Some states, such as California and New York, do not allow pay-if-paid clauses that make subcontractor payment entirely contingent on the contractor being paid. Others, like Texas and Florida, allow them if clearly stated. Always check your state's rules before agreeing to these terms.

Mechanic's liens: Subcontractors in most states have the right to file a mechanic's lien against the property if they are not paid. However, strict notice and filing deadlines apply. For example, in Illinois, a subcontractor must serve a notice within 90 days of last furnishing labor or materials. In Florida, the deadline is 45 days from first furnishing labor or materials for preliminary notice.

Common mistakes:

• Assuming payment will be prompt without confirming the contract schedule.
• Not distinguishing between pay-when-paid (timing) and pay-if-paid (condition) clauses.
• Failing to follow state notice requirements for mechanic's liens.
• Not documenting change orders in writing, leading to disputes over extra work.

Checklist before signing:

• Is the payment schedule clear and realistic?
• Does the contract specify what happens if the owner delays payment?
• Are mechanic's lien rights preserved, and do you know the notice deadlines?
• Are all changes to the work required to be in writing?

Example: A subcontractor in Georgia finishes drywall work but is not paid because the owner is in a dispute with the general contractor. If the contract has a pay-if-paid clause, and Georgia law allows it, the subcontractor may not be entitled to payment until the contractor is paid. If the clause is not enforceable, the subcontractor can demand payment regardless of the owner's actions.

Liability, Insurance and Indemnity: Who Bears the Risk?

Construction projects involve significant risks, including property damage, injuries, delays, and defective work. The subcontract agreement should clearly allocate these risks and specify required insurance coverage.

• Liability for Defects: Who is responsible if the subcontractor's work is defective or causes damage?
• Indemnity Clauses: Does the subcontractor have to reimburse the contractor for certain claims, or vice versa?
• Insurance Requirements: What types and amounts of insurance must the subcontractor carry (general liability, workers' comp, auto, professional liability)?
• Limitation of Liability: Are there caps on damages or exclusions for certain losses?
• Waivers of Subrogation: Do the parties agree not to pursue each other's insurers for damages?

State caveats: Many states restrict indemnity clauses that require a subcontractor to indemnify a contractor for the contractor's own negligence. For example, California and New York prohibit broad form indemnity clauses in construction contracts. Texas allows limited indemnity if the contract meets specific requirements. Always check your state's construction contract statutes.

Insurance: Most contracts require subcontractors to provide certificates of insurance before starting work. General liability insurance is standard, but some projects require additional coverage, such as pollution liability or builder's risk. The contract may require the subcontractor to name the contractor as an additional insured.

Checklist for liability and insurance:

• Who is responsible for property damage, injury, or defective work?
• What insurance policies and limits are required?
• Are you required to name the contractor as an additional insured?
• Are indemnity clauses allowed under your state's law?
• Are there waivers of subrogation or limits on liability?

Example: A subcontractor in Illinois accidentally damages an elevator while installing HVAC equipment. The contract requires the subcontractor to carry $2 million in general liability insurance and indemnify the contractor for damages caused by the subcontractor's negligence. However, if the contractor was also negligent, Illinois law may limit the subcontractor's indemnity obligation.

Common mistakes:

• Not reviewing insurance requirements or providing proof of coverage.
• Agreeing to broad indemnity clauses that are unenforceable in your state.
• Assuming your existing insurance covers all contract requirements.

Termination and Dispute Resolution Clauses

Not all construction projects go as planned. The subcontract agreement should address how the contract can be terminated and how disputes are resolved.

• Termination for Cause: When can the contract be ended for breach, such as failure to perform, defective work, or missed deadlines?
• Termination for Convenience: Can either party end the contract for any reason, and what notice is required?
• Payment on Termination: How is payment handled if the contract ends early? Are there penalties or final payments?
• Dispute Resolution: How will disputes be resolved (mediation, arbitration, court)?
• Governing Law and Venue: Which state's law applies, and where will disputes be heard?

Termination for convenience: Many contracts allow the contractor to terminate the subcontract at any time, sometimes with as little as 7 or 14 days' notice. The subcontractor is usually entitled to payment for work performed up to termination, but not for lost profits on unperformed work. Always check the notice requirements and payment terms.

Dispute resolution: Some contracts require mediation or arbitration before litigation. For example, the American Arbitration Association is a common provider. Some states, such as Florida, have statutes governing construction arbitration. The contract may also specify a particular court or state law, even if the project is in another state.

Checklist for termination and disputes:

• What are the grounds and notice requirements for termination?
• How is payment calculated if the contract ends early?
• What is the process for resolving disputes?
• Which state's law and courts will apply?

Example: A contractor in Florida terminates a subcontractor for convenience. The contract requires 10 days' written notice and payment for completed work. The subcontractor is not entitled to lost profit on unfinished work. If a dispute arises, the contract requires mediation in Miami under Florida law.

Common mistakes:

• Not reading or understanding termination clauses.
• Assuming you will be paid for all work, including unperformed work, if terminated early.
• Not knowing the steps or deadlines for dispute resolution.

Recordkeeping, Notices and Change Orders

Accurate records are essential in construction projects, especially if there is a dispute over payment, scope, or quality. The subcontract agreement should specify what records must be kept, how notices are given, and how changes are approved.

• Recordkeeping: Timesheets, delivery receipts, inspection reports, daily logs, and photos of work performed.
• Notice Requirements: How and when notices must be given (in writing, by email, certified mail, or other method).
• Change Orders: How changes to the scope, price, or schedule are approved and documented.

State caveats: Many states require preliminary notice to preserve mechanic's lien rights. For example, in California, a preliminary notice must be served within 20 days of first furnishing labor or materials. In Texas, a monthly notice is required for unpaid work. Missing notice deadlines can mean losing the right to file a lien.

Change orders: Verbal agreements are risky and often unenforceable. Always get change orders in writing, signed by both parties, before performing extra work. This protects both parties and avoids disputes about payment for additional work.

Checklist for recordkeeping and notices:

• Keep copies of all signed contracts, change orders, and correspondence.
• Document work performed with daily logs, photos, and delivery receipts.
• Follow contract notice requirements exactly, including deadlines and delivery methods.
• Track deadlines for preliminary notices, lien filings, and claims.

Example: A subcontractor in North Carolina performs extra electrical work at the contractor's request. The change order is not signed in writing. When the contractor refuses to pay, the subcontractor has little legal recourse because the contract requires all changes to be in writing.

Common mistakes:

• Failing to keep detailed records of work performed and materials delivered.
• Missing notice deadlines for mechanic's liens or claims.
• Relying on verbal agreements for changes to the scope or price.

State Licensing, Mechanic's Liens and Special Rules

Construction law is highly state-specific. In addition to contract terms, you must comply with state licensing, lien, and payment laws.

• Contractor Licensing: Most states require contractors and subcontractors to be licensed for certain work. Check your state's contractor licensing board for requirements. Unlicensed work can result in fines, loss of payment rights, or even criminal charges.
• Mechanic's Liens: Subcontractors can file a mechanic's lien if not paid, but strict notice and filing rules apply. Each state sets its own deadlines and procedures. For example, in Pennsylvania, a subcontractor must file a lien within six months of last work. In Arizona, the deadline is 120 days.
• Prompt Payment Laws: Many states require contractors to pay subcontractors within a set time after receiving payment from the owner. Penalties for late payment may include interest or attorney fees.
• Indemnity and Insurance Rules: Some states limit or ban certain indemnity clauses or set minimum insurance requirements for construction contracts.

Checklist for state compliance:

• Are you and your business properly licensed for the work?
• Do you know your state's mechanic's lien notice and filing deadlines?
• Does the contract comply with state prompt payment and indemnity rules?
• Do you need to provide a bond or additional insurance?

Example: A subcontractor in some states is not licensed for the type of work performed. When the contractor refuses to pay, the subcontractor cannot enforce payment in court, as another state law bars unlicensed contractors from suing for unpaid work.

Official sources for contractor licensing and mechanic's lien rules include your state's contractor licensing board, secretary of state, and state statutes on construction and liens. If you are unsure, consider consulting a qualified attorney familiar with construction law in your state.

FAQs

What is the difference between a contractor and a subcontractor?

A contractor is hired by the property owner to manage and deliver the overall construction project. A subcontractor is hired by the contractor to perform a specific part of the work, such as electrical, plumbing, or framing. Both have legal obligations under their respective contracts, but the subcontractor's agreement is with the contractor, not the property owner.

Can a subcontractor file a mechanic's lien if not paid?

In most states, subcontractors have the right to file a mechanic's lien against the property if they are not paid for their work. However, strict notice and filing deadlines apply, and the process varies by state. Failure to follow the required steps can result in losing lien rights. Always check your state's rules before starting work.

Are pay-if-paid clauses enforceable in every state?

No, not all states enforce pay-if-paid clauses. Some states limit or ban these clauses because they can unfairly shift the risk of owner nonpayment to subcontractors. Always review your state's construction contract statutes and consider legal advice if your contract includes a pay-if-paid or pay-when-paid clause.

What insurance does a subcontractor need?

Most subcontract agreements require subcontractors to carry general liability insurance, workers' compensation, and sometimes auto or professional liability insurance. The required coverage and limits are usually specified in the contract and may also be set by state law or the general contractor's insurance policy. Always provide proof of insurance before starting work.

Can a contractor terminate a subcontract for any reason?

It depends on the contract. Some subcontract agreements allow termination for convenience, meaning the contractor can end the contract at any time with notice. Others only allow termination for cause, such as breach or failure to perform. Always read the termination clauses carefully and understand your rights and obligations if the contract ends early.
