How to Use E-Verify as a Small Construction Business

Read This First

E-Verify itself is not the hard part. Enrollment takes an afternoon, and the system does one simple thing: it matches government records against the Form I-9 every new hire already fills out ^[1]. The hard part is the deadlines. Miss them and the fines escalate with every repeat violation, and in states like Ohio, enough repeat trouble can cost you your eligibility to bid on state work at all. Enrolling is the easy part. Staying compliant is the part that's moving fast.

Whether any of this applies to you depends on where you work and who you work for. If your state mandates E-Verify for your type of business, you generally have to run it on covered new hires. The details matter, though: some state laws carve out exemptions by employee count, industry, or contract type. If you hold a federal contract yourself above the FAR dollar threshold, a second, separate set of rules kicks in on top of whatever your state already requires. And if you're subcontracting on someone else's federal job, the obligation can reach you too, even though you never signed anything with the government directly. Read the section that actually matches your situation, then move on to what to do next.

The State Map Is the Real Compliance Risk

For most small construction businesses, the state you work in decides whether E-Verify applies at all. As of 2026, more than 20 states have enacted some form of E-Verify requirement, though the rules vary considerably by employer size, industry, and contract type ^[2]. Nine of them require it for all employers: Alabama, Arizona, Georgia, Louisiana, Mississippi, North Carolina, South Carolina, Tennessee, and Utah ^[2]. Alabama alone splits by headcount, requiring the federal system for employers with 25 or more employees while smaller shops may use the state version ^[3].

Ohio is the one to study, because it targets your trade directly. The E-Verify Workforce Integrity Act took effect March 19, 2026, and requires every nonresidential construction contractor, subcontractor, and labor broker in the state to run E-Verify on every new hire ^[4]. The penalties are structured to escalate: failing to create a case starts at $250 for a first violation, rises to $1,000 for a second violation within three years, and hits $1,500 for any violation after that ^[4], while continuing to employ someone after a final nonconfirmation runs $5,000, then $10,000, then $25,000 ^[4]. Willful repeat violations can also bar a contractor from bidding on state work for up to two years ^[5]. Ohio also requires you to keep verification records for three years after the hire date or one year after termination, whichever is longer ^[4].

If You Hold a Federal Contract, There's a Second Clock

Everyone running E-Verify follows the same basic rule: once a new employee begins work, you have three business days to create their case ^[3]. If you also hold a federal contract over $150,000 with a period of performance of 120 days or more ^[6], or you're a sub on one, the FAR E-Verify clause adds a second clock on top of that. Enroll within 30 days of the contract award. Within 90 days of enrollment, you must begin using E-Verify for new hires; after that 90-day window, new hires follow the normal three-business-day timeline. Employees already assigned to the contract have a separate deadline: 90 days from your enrollment date or 30 days from their assignment, whichever is later ^[3]. Suppliers are carved out, and only the legal entity that signs the contract is bound ^[7]. If you're genuinely self-employed with no other employees, you generally don't need to run E-Verify on yourself, since you don't complete an I-9 on yourself ^[7].

The $3,500 Threshold That Catches Subcontractors Off Guard

You don't have to sign a federal contract yourself to be bound by this. If your subcontract for services or construction on a covered federal job exceeds $3,500 and the work is performed in the United States, the E-Verify obligation reaches you too, even though the government never sees your name on the prime contract ^[6][7]. That's a low bar for a construction subcontract. Check your subcontract value against it before you assume the federal rules don't apply to you.

What to Do

Start by enrolling at the official site, e-verify.gov, and set aside uninterrupted time, because enrollment must be completed in a single web session ^[8]. Have your Employer Identification Number ready, since every company needs it to enroll ^[8]. If you take federal contract work, you will also need your Unique Entity Identifier during enrollment ^[8]. Once you are in, build the three-business-day rule into your onboarding checklist so verification happens with the I-9, not weeks later ^[3]. Assign one person to own it, the same way you would assign a foreman to a punch list.

Now cross-check every state you actually work in against the rules above before you bid, not after you win. Ohio's record-retention requirement is a useful default even where it is not mandated: keep verification records three years after hire or one year after termination ^[4]. One more operational note: E-Verify has gone dark before during a federal shutdown, and employers were still required to create cases for anyone hired on or after October 1 once the system came back ^[1]. Build a paper trail for outages so a system being down does not become your compliance gap.

Bottom Line

Enrolling in E-Verify is an afternoon of work; staying compliant is a standing process tied to your onboarding clock and to every state line you cross. Set the three-day rule and the state map before your next hire, not after your next audit.
