Subcontractor Agreement Template: What to Include (With Free Download)

A solid subcontractor agreement template is the cheapest insurance policy a contractor can buy. You'll use it dozens of times a year, it costs nothing once you have a good one, and it's the difference between a clean dispute resolution and a drawn-out nightmare when something goes sideways on a job.

If you're still operating on handshakes, texts, or a half-page scope stapled to a purchase order, you're one bad sub away from a serious loss. This post walks through exactly what belongs in a subcontractor agreement template, why each clause matters, and how to adapt one for residential renovation, HVAC, plumbing, or flip work.

Why a Written Subcontractor Agreement Matters

Subcontractor disputes are almost always avoidable. The pattern is the same every time: two parties assumed different things about scope, schedule, or payment, and neither bothered to write it down. By the time it becomes an argument, it's too late to fix cheaply.

A written subcontractor agreement does three things that a verbal deal can't:

It forces both sides to agree on specifics before work starts. When you write "replace drywall in master bath" versus "complete drywall rough-in through level-5 finish ready for paint," you're eliminating 80% of the scope fights before they happen. The conversation you have drafting the agreement is more valuable than the document itself.

It gives you legal leverage. If a sub walks off the job, damages property, or fails to carry insurance, your agreement is what you hand an attorney. Without it, you're arguing "he said, she said" and your recovery odds drop off a cliff.

It protects the sub, too. Good subs actually want written agreements because it means they get paid on the terms everyone agreed to, not what the GC decides later. If a sub pushes back on signing a reasonable agreement, that's a red flag worth paying attention to.

What Every Subcontractor Agreement Must Include

A subcontractor agreement template doesn't need to be 40 pages of legalese. The best ones are 3-5 pages of specific, readable language. Here are the sections you can't skip.

1. Parties and Project Identification

Start with the basics: legal business names of both parties, addresses, license numbers if applicable, and the specific project this agreement covers. Include the project address, a short project description, and your prime contract number if you track them.

This sounds obvious, but vague "parties" language causes real problems. "Mike's HVAC" isn't a legal entity — "Mike Johnson LLC dba Mike's HVAC" is. If you ever need to collect on a bond, lien, or insurance claim, you need the right legal name on the agreement.

2. Scope of Work

This is the single most important section. Be ruthlessly specific. If you're vague here, every other clause in the agreement becomes weaker.

A good scope section includes what's included, what's explicitly excluded, the specifications or plans being followed, and the standard of workmanship expected.

For example, don't write: "Install HVAC system per plans."

Write: "Furnish and install one (1) 3-ton Carrier 24ACC636A3 condenser, one (1) matched Carrier FB4CNF036 air handler with 15 kW electric heat strip, 7 supply registers and 2 returns per Sheet M1.1 dated 3/15/2026. Includes refrigerant line set up to 25 ft, low-voltage thermostat wiring, and standard condensate drain routing. Excludes: electrical disconnect (by others), gas line modifications, and any duct modifications beyond what is shown on plans."

That level of detail takes five extra minutes when drafting and saves five hours of arguments later.

3. Price and Payment Terms

Spell out the total contract price, progress payment schedule, retainage (if any), and payment timing. Every single element.

Common structures include a flat lump-sum price with progress draws tied to milestones (e.g., 30% rough-in complete, 60% trim-out, 10% final), time-and-materials with a not-to-exceed cap, and unit pricing for repetitive work (per fixture, per linear foot, etc.).

Also specify:

• When payment is due (e.g., "within 10 days of invoice approval")
• What triggers payment (milestone completion, inspection pass, owner payment)
• Retainage percentage and release conditions (typically 5-10%, released at substantial completion)
• Late payment consequences (interest, stop-work rights)

The "pay-when-paid" vs. "pay-if-paid" distinction matters here. Pay-when-paid means you'll pay the sub on reasonable timing after you get paid. Pay-if-paid means the sub only gets paid if you do — which shifts owner credit risk onto the sub. Pay-if-paid clauses are unenforceable in some states, so know your local law.

4. Schedule and Completion

Include the start date, substantial completion date, and milestone dates for larger jobs. Address the consequences of delays on both sides.

Be realistic. If you put "start date: immediately" on every agreement and then push subs around, they stop taking your dates seriously. Tie schedule to notice — "start within 5 business days of written notice to proceed" — so you control timing without over-committing the sub.

Include force majeure language (weather, supply delays, owner delays) so a legitimate delay doesn't trigger penalties, but make sure it requires prompt written notice — a sub can't claim force majeure three weeks after the fact.

5. Insurance and Licensing Requirements

This is the clause that saves your business. Specify minimum coverage limits and required endorsements.

A standard residential subcontractor requirement package looks like this:

• General liability: $1M per occurrence, $2M aggregate
• Workers' compensation: statutory limits in the project state
• Auto liability: $1M combined single limit if the sub drives to the site
• Additional insured status for the GC on general liability
• Waiver of subrogation on workers' comp
• Certificate of insurance delivered before work starts

Add a clause that says no work may begin until a current COI is on file, and that the sub must notify you of any mid-term policy changes or cancellations. One uninsured sub-injured worker can wipe out a small contractor's entire business.

6. Indemnification

Your indemnification clause shifts liability for the sub's negligence back to the sub. In plain English: if the sub (or their employees) hurts someone, damages something, or creates a legal problem, the sub covers it — not you.

Keep it mutual but proportional. A reasonable indemnification clause covers the sub's negligent acts and omissions, not claims caused by your own negligence. Overly broad indemnification clauses (where the sub indemnifies you for your own negligence) are unenforceable in many states under "anti-indemnity" statutes.

7. Change Orders

Spell out the change order process. Changes are inevitable — undocumented changes are where money gets lost.

Require:

• All changes in writing before the work is performed
• A change order form specifying scope, price, and schedule impact
• Signatures from both parties
• No obligation to pay for unauthorized work

This single clause, enforced consistently, saves more money than almost any other contract provision.

8. Warranties and Defect Liability

Specify the warranty period (typically 1 year for workmanship, pass-through on manufacturer warranties for materials), what it covers, and how the sub responds to warranty calls. Include a clause requiring the sub to respond within a reasonable time — usually 48-72 hours for emergency issues.

9. Termination

Include both "for cause" and "for convenience" termination language. For cause covers material breach (no-show, uninsured work, defective work). For convenience lets you part ways without cause if you pay for work completed to date. This gives you flexibility without making every termination a legal fight.

10. Lien Waivers

Require conditional lien waivers with each progress payment and an unconditional final waiver at project close. This keeps liens from surprising you six months after the job closes. Use your state's statutory waiver forms where required — some states void non-statutory waivers entirely.

Common Subcontractor Agreement Mistakes

Even contractors who use written agreements make predictable mistakes. Here are the ones that cost the most money.

Using a generic template without customizing scope. A template is a starting point, not a finish line. The scope section needs to be written from scratch for every job. If you're copy-pasting the same scope across different jobs, you're going to lose a scope fight eventually.

Signing after work starts. If the sub is already three days into the job and you're just now getting the agreement signed, your leverage is gone. Sign before the first nail goes in.

Ignoring flow-down provisions. If your prime contract with the owner requires specific provisions (liquidated damages, specific insurance limits, schedule penalties), your subcontractor agreement needs matching flow-down language. Otherwise you're eating the owner's demands yourself.

Waiving lien rights in advance. Some GCs include blanket lien waivers as part of the agreement. This can backfire badly in multiple states and is increasingly viewed skeptically by courts. Use waivers tied to actual payments instead.

Not updating your template. State laws change. Insurance standards change. If you're using the same subcontractor agreement you built in 2019, have a construction attorney review it.

How PropertyHQ Manages Subcontractor Agreements

Managing subcontractor agreements on paper or in email threads is where things fall through the cracks. Agreements get lost, COIs expire without anyone noticing, and you end up chasing paperwork at month-end.

PropertyHQ's Subcontractor module keeps every agreement, COI, W-9, and license tied to the sub's profile. Agreements are tracked per project, with scope, payment schedule, and lien waiver status visible alongside the work itself. When a COI is about to expire, the system flags it before you book the sub for another job — not after they show up on site uninsured.

For flippers and renovation GCs juggling 5-15 active subs, the difference between "we have a system" and "we have a stack of paper" shows up in your margins at the end of every project.

Getting Started With Your Template

A subcontractor agreement template isn't a one-and-done document. Treat it as a living document you refine over time.

Start with a solid base (the structure above covers what matters), customize the scope section for every job, review it annually with a construction attorney in your state, and track the agreements you've signed in one place so you can find them when you need them — not when it's too late.

A tight agreement costs you fifteen minutes on the front end and saves you tens of thousands on the back end. That's the kind of math every contractor should be doing.
