Subcontractor JSA Requirements: What GCs Expect From Subs

OSHA does not require a subcontractor to write a JSA by name. The requirement usually comes from the general contractor, through the subcontract, the site safety plan, or the owner's contract. Typically a GC asks subs for a JSA for each significant task before the work starts, signed by the crew, kept on site, and handed over on request. This article covers what GCs commonly ask for, how to find out exactly what your GC wants, and how a small sub can meet those requests without drowning in paperwork.

Where the Requirement Comes From

There is no federal rule that says "every sub must submit a JSA." What does apply to every employer is the General Duty Clause, which requires a workplace free of recognized hazards, and on construction sites the duty to instruct each employee in recognizing and avoiding unsafe conditions (29 CFR 1926.21(b)(2)). A JSA is one common way to plan the work and document the instruction. GCs turn that into a requirement because they want evidence that every trade on their site has thought through its work, and because owners and insurers often ask them for it.

So the requirement lives in documents you can read: the subcontract, the safety exhibit attached to it, the project safety plan, and the prequalification questionnaire. Read them before the first day, and ask the GC's safety manager if anything is unclear. For the broader OSHA picture, see OSHA requirements for a job safety analysis.

What GCs Commonly Ask Subs For

Requirements differ from one GC and one project to the next. These come up often.

• A JSA for each task, before the task starts. Some GCs want them submitted ahead of work. Others want them on site and available on request. Know which.
• Task-level detail. Steps, hazards, and controls specific to the work, not a generic page. Reviewers notice when the same text appears on every job.
• Signatures from the crew. Everyone doing the work signs, with name, company, and date. Some GCs also want the supervisor's name on it.
• Named responsible people. The foreman or supervisor leading the work, and where a hazard calls for one, the competent person.
• Revisions when the work changes. If the task, location, or conditions change, the GC expects the JSA to change with them.
• Records available for audits. Site safety audits often sample JSAs from the subs on site that day.
• Sometimes, their own form. Many GCs have a required JSA or pre-task form. If yours does, use it.

How to Find Out What Your GC Wants

1. Read the safety exhibit in your subcontract. Look for the words JSA, JHA, AHA, pre-task plan, and activity hazard analysis. They are used loosely, and the title matters less than what the document must contain. If you run into the terms, JSA vs JHA explains how they relate.
2. Ask four questions at the pre-construction meeting: Do you require a specific form? When must JSAs be submitted? Who reviews them? How are revisions handled?
3. Ask for an example. A GC's safety manager can often show an accepted JSA for a similar trade, which tells you the level of detail expected.
4. Write down the answers. Keep the answers with the project file so every foreman on your crew works to the same expectations.

How a Small Sub Can Meet Those Requests

Write the JSA for the task, from the actual job

A GC reviewer can tell in seconds whether a JSA was written for this site. Name the real hazards: the overhead line, the opening in the deck, the other trade working below. Common JSA mistakes lists what reviewers tend to catch.

Use a tool that does the structure for you

In JSA Generator you pick the work activity, the AI drafts the steps, hazards, and controls, and a supervisor edits them to fit the job before finalizing. Each hazard is rated before controls and again after, banded Low, Medium, High, or Extreme. If your GC requires its own form, use that form. A JSA Generator PDF can sit alongside it as the more detailed task plan, if the GC accepts that.

Get the crew to sign every time

A finalized JSA is a US Letter PDF with a QR code. Each crew member scans it with their own phone, enters their name and company, and signs on screen. No account or app is needed, and each signature is stored with the name and the time. That helps a sub whose crew changes from week to week. See how to get a crew to sign a JSA for the routine.

Keep the records where you can find them

Finalized JSAs stay in your JSA library with their signatures, and downloading the PDF again includes the signatures, which makes it easy to send a GC what they ask for. If a GC wants an editable file, the Pro plan includes Word export. Filing advice is in JSA record-keeping.

What It Costs a Small Sub

Drafts and edits are free, and a JSA counts the first time you finalize it. The plans:

• Free: 1 finalized JSA a month, with a watermark on the PDF.
• Single JSA: $9 for one finalized JSA, no watermark, no subscription, and the credit never expires.
• Starter: $19 a month for 10 finalized JSAs.
• Pro: $49 a month for 50 finalized JSAs, with 3 seats and Word export.

If your GC wants a clean PDF with no watermark, the Free plan will not do, so choose a Single JSA or a monthly plan. See the pricing page for current prices.

Checklist for the First Week on a New GC's Site

1. Read the safety exhibit, and note every JSA-related requirement.
2. Ask whether a specific form is required and when JSAs are due.
3. Name the foreman and the competent person for each major task.
4. Draft and finalize the JSA for your first task before the crew starts.
5. Brief the crew and have everyone sign.
6. Revise and re-sign when the task or conditions change.
7. File the signed PDFs by project and date.

Following these steps helps you document your work. They do not guarantee a GC will accept your paperwork, since each GC sets its own standard.

Frequently Asked Questions

Does OSHA require subcontractors to submit JSAs to the GC?

No. OSHA does not require a JSA by name. The submission requirement comes from the GC's contract or site safety plan, so read those documents.

Can I use my own JSA format on a GC's site?

Sometimes. Many GCs accept any format that covers the required content, and others insist on their own form. Ask before the work starts.

Who signs the JSA, the foreman or the whole crew?

Everyone doing the work should read and sign, and the foreman or supervisor who led the briefing should be named. Check whether your GC also wants the supervisor's signature.

Do I need a JSA for every task on a small job?

Write one for each distinct task that carries meaningful hazards, and follow your GC's threshold if it sets one. For short, simple, low-risk tasks, ask the GC what level of paperwork they expect.

Start With Your Next GC Request

Take the next JSA your GC asks for, draft it, edit it to the site, and have the crew sign it from their phones.
