Subcontractor Agreement
A subcontractor agreement sets the terms between a general contractor and a subcontractor brought on for a specific part of a job — scope, payment, insurance requirements, and who is liable if something goes wrong on site. On a fast-moving project, this is often the document most likely to get skipped in favor of a verbal understanding.
Verbal agreements do not hold up when a job goes over budget
A subcontractor relationship built on a phone call and a handshake works fine until a change order comes up, a payment is delayed, or an injury on site raises a liability question no one discussed in advance. Construction disputes are common precisely because scope and payment terms are frequently left informal, and by the time a disagreement surfaces, both sides may remember the original conversation differently.
What the template covers
Scope of work tied to the specific job
What the subcontractor is responsible for, referencing the specific project and plans — vague scope language is the single most common source of dispute on a construction job.
Payment schedule tied to milestones
When payment is due — on completion, at defined milestones, or on a schedule — with a clear process for handling delayed payment from either direction.
Insurance and liability requirements
What insurance coverage the subcontractor must carry and provide proof of, and how liability for damage or injury is allocated between the parties.
Change order process for added work
How additional work beyond the original scope is requested, priced and approved — signed in the field before the work starts, not negotiated after it is already done.
How subcontractor agreements are treated legally
Subcontractor agreements are governed by general state contract law, with construction-specific statutes in most states covering mechanic's liens, prompt payment requirements, and licensing rules for contractors and subcontractors — these vary meaningfully by state and by the size of the job. The agreement itself is validly signed electronically under the ESIGN Act, 15 U.S.C. § 7001, which matters in practice on a job site where signing in the field, from a phone, is often more realistic than returning to an office. This is general information — confirm your state's specific licensing and lien-notice requirements before relying on a template alone.
A change order that was never signed
A general contractor verbally asked a subcontractor to add electrical work beyond the original scope midway through a residential project, with an informal understanding that it would be billed "at the usual rate." When the invoice arrived well above what the general contractor expected, there was no signed change order to confirm what rate had actually been agreed, or that the additional work had been authorized at all. The dispute delayed the project's final payment by several weeks — a one-paragraph change order, signed on a phone before the work began, would have settled the rate before either side had a reason to disagree about it.
Questions people ask about this
What is the difference between a subcontractor agreement and an independent contractor agreement?
A subcontractor agreement is typically a specific application of independent contractor terms, structured for a construction or trade context — scope tied to a job site, insurance requirements, and lien-related provisions specific to construction.
Can this be signed on-site from a phone?
Yes — the signing flow works from any mobile browser, which matters specifically for construction work where returning to an office to sign is often impractical.
Does the agreement need to address mechanic's liens?
In most states, yes — subcontractors generally retain lien rights against the property if unpaid, and many states require specific notice language. Confirm your state's exact requirement, since failing to include required notice can affect lien rights.
Who is liable if the subcontractor's work causes damage?
This should be addressed explicitly in the agreement's liability and insurance clauses — without it, the allocation of responsibility depends on general state law principles that may not match what either party expected.
