Question 1

What is the difference between a subcontractor and an independent contractor?

Accepted Answer

Both subcontractors and independent contractors are non-employees operating their own business and paying self-employment tax, but the structural relationship differs. An independent contractor is hired directly by the end client (the homeowner, the company buying services). A subcontractor is hired by a prime contractor who has a primary contract with the end client, and the subcontractor performs a portion of that prime contract's scope. This two-tier structure creates unique legal issues: lien rights against the end client's property even though the subcontractor has no direct contract with the owner, pay-when-paid and pay-if-paid clauses that make the prime's receipt of payment a condition of the sub's right to be paid, and flow-down obligations that push the prime's contract terms (including AIA A401 provisions and federal FAR clauses) down to the subcontractor.

Question 2

How does a subcontractor agreement protect the prime contractor from IRS reclassification?

Accepted Answer

The IRS uses a multi-factor common-law control test to distinguish employees from independent subcontractors, and the Department of Labor now applies a 2024 six-factor economic reality test under the Fair Labor Standards Act. A solid subcontractor agreement strengthens the classification by documenting that the sub controls methods, tools, staffing, and schedule; by tying payment to deliverables or milestones rather than hours worked; by requiring the sub to carry its own insurance and licenses; and by permitting the sub to work for other clients. Many states (California under AB 5, New Jersey, Massachusetts) apply a stricter ABC test that presumes employment unless the prime can prove all three factors — the sub is free from control, the work is outside the prime's usual business, and the sub operates an independently established trade. A tightly drafted subcontract is the single most important piece of evidence in defending against a misclassification audit.

Question 3

What insurance should a subcontractor carry?

Accepted Answer

At minimum, require commercial general liability (CGL) insurance with limits of $1 million per occurrence and $2 million aggregate, automobile liability of $1 million combined single limit, statutory workers' compensation, and employer's liability of $500,000 or more. For higher-risk trades — roofing, demolition, blasting, crane work — layer on a $5 million excess/umbrella policy. For professional subs (engineering, IT consulting, design-build), add professional liability (E&O) coverage. Specialty trades need additional coverage: pollution liability for cleaning and environmental work, cyber liability for IT and HIPAA subs, inland marine for tool and equipment coverage, and contractors equipment floater for heavy machinery. Always require the sub to name the prime contractor and the owner as additional insureds on a primary, non-contributory basis using ISO endorsements CG 20 10 (ongoing ops) and CG 20 37 (completed ops).

Question 4

What is a lien waiver and how does it work for subcontractors?

Accepted Answer

A lien waiver is a document in which a subcontractor or supplier gives up the right to file a mechanic's lien against the project property in exchange for payment. Every construction subcontract should require conditional progress lien waivers before each progress payment and a final unconditional lien waiver before releasing retainage. Several states — California (Civil Code §§ 8132, 8134, 8136, 8138), Texas (Chapter 53 Property Code), and Florida (§ 713.20, Fla. Stat.) — have statutory lien waiver forms that must be used verbatim to be enforceable. Using the wrong form, even by small wording differences, can void the waiver. Without lien waivers, the prime contractor and the property owner are exposed to double-payment risk: if the sub doesn't pay its own crew or suppliers, those parties can file liens against the owner's property even though the owner already paid the prime.

Question 5

Is a pay-if-paid clause enforceable?

Accepted Answer

A pay-if-paid clause states that the prime contractor's receipt of payment from the owner is a condition precedent to the prime's obligation to pay the subcontractor. It shifts the risk of owner insolvency from the prime down to the sub. Enforceability varies sharply by state. California (Wm. R. Clarke Corp. v. Safeco Ins. Co.), New York (West-Fair Electric Contractors v. Aetna), and North Carolina have refused to enforce pay-if-paid clauses on public-policy grounds or have construed ambiguous language as pay-when-paid timing provisions. Other states enforce them if the language is explicit and unambiguous, typically requiring words like 'condition precedent' and 'sub assumes the risk of owner nonpayment.' On federal prime contracts and most public projects, the Prompt Payment Act (31 U.S.C. § 3905) overrides pay-if-paid by requiring the prime to pay subs within 7 days of receiving payment from the government.

Question 6

What is flow-down and why does it matter for subcontractors?

Accepted Answer

Flow-down clauses push the prime contract's material terms down to the subcontractor. On federal prime contracts, certain FAR clauses (FAR 52.244-6 mandatory flowdown, Davis-Bacon prevailing wage clauses, Service Contract Act, EEO) must be included in every subcontract by law. On private AIA contracts, AIA A401 is the standard subcontract template that flows down AIA A201 general conditions. Flow-down ensures that the sub is bound by the same notice requirements, change order procedures, warranty obligations, dispute resolution, and termination rights that the prime is. It also protects the prime from whipsaw claims — the prime cannot be required to perform differently for its subs than the owner is required to for the prime. Subs need to read flow-down language carefully because it can dramatically expand their obligations beyond the four corners of the subcontract.

Question 7

When does OCIP or CCIP wrap-up insurance apply?

Accepted Answer

Owner-Controlled Insurance Program (OCIP) and Contractor-Controlled Insurance Program (CCIP) wrap-up policies provide a single master insurance program covering the owner, prime contractor, and all enrolled subcontractors on a large project. Wrap-ups typically provide CGL, workers' compensation, and excess liability for construction operations at a specified job site. When a project is wrap-enrolled, the subcontractor agreement must specify how wrap coverage interacts with the sub's own policies (typically the wrap is primary for on-site operations and the sub's policy covers off-site and completed operations), require the sub to maintain its practice policies for off-site exposures, and adjust bid pricing to reflect the insurance credit. Most wrap-ups apply only to projects over $50-100 million in construction value. Always obtain an OCIP or CCIP manual and enrollment certificate before mobilization.

Question 8

What happens if a subcontractor abandons the job?

Accepted Answer

Abandonment is a material breach and an event of default under a well-drafted subcontract. The prime contractor should issue a written default notice with a short cure period (typically 48-72 hours), then terminate for default if the sub fails to cure. After termination, the prime has the right to take possession of the sub's materials and tools left on site, complete the work with another sub or in-house crew, and back-charge the abandoning sub for all excess completion costs (the difference between the abandoning sub's contract price and the actual cost to complete). The prime should also call on the sub's performance bond (if any) or notify the subcontractor default insurance (SDI/SubGuard) carrier, preserve all evidence of the abandonment, and mitigate damages through prompt procurement. Document the condition of the work at takeover with photographs and dated inspection reports to defeat the sub's inevitable claim that the work was properly performed.

Question 9

Does a subcontractor need a contractor's license?

Accepted Answer

In most states, yes — subcontractors performing licensed trade work must hold the appropriate state contractor's license, and the prime should verify license status through the state licensing board before executing the subcontract. California (Business & Professions Code § 7031), Nevada, Arizona, and Florida bar unlicensed contractors from suing to collect payment and in some cases require disgorgement of money already paid. The license requirement varies by trade and dollar threshold: general building ($500 threshold in California), electrical, plumbing, HVAC, roofing, and concrete typically require licensure. Some states license individuals (journeyman/master cards); others license businesses; most require both. Federal projects add requirements beyond the state license: registration in SAM.gov, certified payroll under Davis-Bacon, EEO compliance, and sometimes small-business or DBE certification.

Question 10

How is a subcontractor agreement different from an employment agreement?

Accepted Answer

An employment agreement governs an employee who works under the employer's direction and control, is paid a salary or hourly wage with payroll tax withholding, receives benefits (health insurance, retirement, PTO), is covered by workers' compensation paid by the employer, and can be fired at-will (in most states) without cause. A subcontractor agreement governs an independent business that performs work under a contract for a defined scope and price, invoices for its work, pays its own self-employment taxes, carries its own insurance, works for multiple clients, and can only be terminated per the contract's termination clauses (typically for cause or for convenience with notice and payment for work completed). The subcontract should explicitly disclaim employment, state that the sub is an independent contractor, and contain representations and warranties about insurance, licensing, and tax status that support the non-employment classification.

Question 11

What dispute resolution provisions should a subcontractor agreement include?

Accepted Answer

Most subcontractor agreements require mandatory mediation as a condition precedent to arbitration or litigation, followed by binding arbitration under AAA Construction Industry Rules or JAMS Streamlined Arbitration Rules. Arbitration is preferred over litigation because it is faster, cheaper, more private, and allows selection of arbitrators with construction expertise. Some primes retain a unilateral right to choose litigation for certain claims (lien foreclosures, injunctive relief, small claims) while requiring the sub to arbitrate everything else — this is generally enforceable if drafted clearly. Include a prevailing party attorneys' fees clause, a venue clause designating the county where the project is located, a choice-of-law clause selecting the state where the project is located (or the prime's home state), and a waiver of jury trial. For federal disputes, the Contract Disputes Act and the Federal Arbitration Act override state-law procedural rules.

Question 12

How long should records from a completed subcontract be retained?

Accepted Answer

Retain all executed subcontract documents and project records for at least the longer of (a) the statute of limitations for breach of written contract in the project state (typically 4-6 years), (b) the statute of repose for construction defects (often 6-15 years from substantial completion — e.g., 10 years in California under Code of Civil Procedure § 337.15), and (c) the tax records retention period under IRC § 6501 (3 years for most items, 6 years for substantial understatements). For federal prime contracts, FAR 4.703 requires retention of subcontract files for 3 years after final payment, longer for some categories. Best practice is 10-15 years from project completion, which covers virtually all claim windows. Store records electronically with metadata preservation: daily reports, RFIs, change orders, lien waivers, inspection reports, certified payroll, safety records, insurance certificates, and all correspondence. These are the documents that determine the outcome of construction disputes years after the project closes.
