Alabama Subcontractor Insurance Requirements for General Contractors

TL;DR: Alabama requires general liability coverage of at least $300,000 per occurrence for most licensed contractors, and workers' comp is mandatory for employers with 5 or more employees — with meaningful exemptions available for small subs. Before a sub touches your Alabama jobsite, confirm their COI, check their WC status with the Alabama Department of Labor, and have a signed W-9 on file to avoid backup withholding at 24%.

Alabama isn't the most complicated state for contractor compliance, but it has a few quirks that trip up GCs — especially around workers' comp exemptions and the state licensing tiers. Get those wrong and you could end up liable for a sub's injuries, facing a contractor board complaint, or stuck in a lien dispute that should never have happened.

Here's what you actually need to know before hiring subs in Alabama.

Alabama Contractor Licensing: The ASLBC Tier System

The Alabama State Licensing Board for General Contractors (ASLBC) oversees licensing for contractors doing work valued at $50,000 or more. Projects under $50,000 don't require a state license — but some municipalities have their own thresholds, so verify locally.

There are two license tiers:

• Unlimited License: For projects with no cap on value. Requires proof of financial stability, experience, and insurance.
• Limited License: For projects up to $250,000. Same requirements, smaller scope.

Specialty contractors (electrical, plumbing, HVAC, fire protection) are licensed separately through their respective boards:

• Electrical: Alabama Electrical Contractors Board
• Plumbing: Alabama Plumbers & Gas Fitters Examining Board
• HVAC: Alabama Mechanical Contractors Board

When you hire specialty subs, verify their specialty license in addition to general liability and workers' comp. Specialty boards make license lookups easy — use them.

General Liability Insurance Requirements

The ASLBC requires minimum GL coverage to obtain and maintain a contractor's license:

License Type	Minimum GL Per Occurrence	Minimum GL Aggregate
Limited ($50K–$250K projects)	$100,000	$300,000
Unlimited (no cap)	$500,000	$1,000,000

In practice, most GCs require subs to carry at least $1,000,000 per occurrence / $2,000,000 aggregate regardless of license tier — especially on commercial projects where the owner's contract pushes those minimums downstream.

Your subcontract should specify:

• Minimum per-occurrence and aggregate limits
• That the GC is named as additional insured (on both ongoing and completed operations)
• Waiver of subrogation in favor of the GC
• 30 days' notice of cancellation (or 10 days for nonpayment)

These provisions won't appear on the sub's standard policy unless they're specifically requested and endorsed. Always verify them on the actual certificate of insurance and the endorsements page — not just the ACORD 25 summary.

Alabama Workers' Compensation: Who's Covered and Who's Exempt

Alabama's workers' comp law is in Code of Alabama §25-5-50 et seq., administered by the Alabama Department of Labor (ADOL).

Coverage Threshold

Workers' comp coverage is mandatory for employers with 5 or more employees — full-time and part-time combined. Employers with fewer than 5 employees are not required to carry WC under Alabama state law.

This threshold is one of Alabama's most significant quirks. A four-person electrical sub crew might have no legal obligation to carry workers' comp in Alabama. That's good for the sub, bad for you if one of them gets hurt on your site.

Your exposure: If an uninsured sub's worker is injured on your project and can't collect WC from the sub, they may pursue a claim against the GC as the "statutory employer." Alabama courts have upheld statutory employer liability in these situations.

Best practice: Require WC coverage from ALL subs regardless of employee count — or get a signed exemption certificate if they legitimately qualify.

Independent Contractor vs. Employee

Alabama uses a multi-factor test to determine whether someone is a true independent contractor. The core question is control: does the GC control how the work is done, or just the result?

Common misclassification indicators:

• Sub uses GC-supplied tools and materials exclusively
• Sub works exclusively for one GC for an extended period
• GC sets the sub's daily work hours

If the state or an insurer reclassifies a sub as your employee, you're responsible for their WC coverage and associated premiums retroactively.

WC Exemptions for Sole Proprietors and Corporate Officers

Alabama allows WC exemptions for:

• Sole proprietors who don't have employees
• Partners in a partnership who don't have employees
• Corporate officers who own at least 10% of the corporation's stock

To claim an exemption, the individual must file Form WC-8 with the Alabama Department of Labor. Once approved, the ADOL issues a WC exemption certificate.

Your job: Collect the signed exemption certificate before work begins. An oral assurance that someone is "exempt" is worthless in an audit or injury dispute.

What to Collect from Every Alabama Sub

Before a sub starts work on any Alabama project, you should have these documents in hand:

Required Documents

• ACORD 25 Certificate of Insurance — showing GL with your entity named as additional insured
• Additional Insured Endorsement (CG 20 10 / CG 20 37 or equivalent) — the actual endorsement, not just a box checked on the COI
• Workers' Comp Certificate — or a valid ADOL WC exemption certificate
• Alabama contractor license verification — check the ASLBC lookup tool at aslbc.alabama.gov
• Signed W-9 — required before first payment for 1099 reporting purposes
• Signed subcontract — including insurance requirements, indemnification, and compliance obligations

If Using Tiered Subs

If your sub is hiring their own subs (sub-subcontractors), push the same insurance requirements downstream through your subcontract. Require that your direct sub collect COIs from their subs and provide them to you. You don't need a direct contract with the sub-sub, but you need proof of coverage.

Alabama Lien Waiver Laws

Alabama has a statutory lien waiver process under Code of Alabama §35-11-90 et seq., and the rules are more borrower-friendly than many states.

Key Points

No standard state form: Alabama doesn't mandate a specific lien waiver form. Your waiver language needs to be clear and unambiguous — courts have voided vague or overly broad waivers.

Conditional vs. Unconditional:

• A conditional waiver releases lien rights only upon receipt of payment. Used when payment hasn't cleared yet.
• An unconditional waiver releases lien rights regardless of whether payment is received. Use only when the check has actually cleared.

Notice requirements: Subcontractors and suppliers in Alabama must file a Statement of Lien within 6 months of the last date of work or materials supplied. The lien is filed in the county where the property is located.

Your risk: If a sub you paid releases a conditional waiver but their check bounces or is disputed, they can still file a lien. Always match the waiver type to the actual payment status.

Best practice: Collect a conditional waiver at payment, then follow up with an unconditional waiver once the check clears. PaperBoss lets you track waiver status by payment milestone so nothing slips through.

W-9 and 1099 Requirements for Alabama Subs

Alabama follows federal IRS rules for 1099-NEC reporting. You must file a 1099-NEC for any sub (individual or partnership) paid $600 or more in a calendar year for construction services.

W-9 Best Practices

• Collect W-9 before the first payment, not at year-end
• Keep W-9s on file for 4 years after the tax year
• If a sub refuses to provide a W-9, withhold 24% backup withholding from payments and remit to the IRS

IRS penalties for missing 1099s: $310 per form for intentional disregard. For non-intentional failures filed late, penalties range from $60 to $310 per form depending on how late they are.

LLCs and S-Corps

• Single-member LLCs and partnerships — 1099 required
• S-Corps and C-Corps — generally exempt from 1099-NEC (though you still need a W-9 to confirm their entity type)

When in doubt, collect the W-9 and let the entity type determine whether you file. It costs nothing to have the W-9 and potentially thousands to not have it.

Alabama-Specific Risks and Gotchas

Hurricane and Wind Exposure

Alabama's Gulf Coast counties — Mobile and Baldwin — are high-risk wind/hurricane zones. For projects near the coast, verify that your sub's GL policy doesn't exclude named storm damage. Wind exclusions are increasingly common in Gulf South policies post-Hurricane Ida and -Sally.

Ask for the declarations page in addition to the COI for coastal projects. The declarations page will show exclusions the ACORD 25 won't.

Agricultural and Rural Projects

Parts of Alabama are heavily agricultural. Farm structures and certain agricultural equipment work may fall outside standard contractor coverage. If your project involves farm buildings, timber operations, or rural utility work, verify coverage specifically covers that exposure.

Home Builders Licensure Act

Residential contractors doing new homes or major renovations must also comply with the Alabama Home Builders Licensure Board requirements under §34-14A-1 et seq.. This is separate from the ASLBC. If you're a commercial GC crossing into residential work, or if your residential sub isn't properly licensed with the HBLB, that's both a legal risk and an insurance gap.

Alabama Compliance Checklist for GCs

Before work begins on any Alabama project, confirm each sub has provided:

• Valid ASLBC or specialty license (verified, not just self-reported)
• Certificate of Insurance — GL, WC, auto (minimum limits per your subcontract)
• Additional insured endorsements on GL policy (ongoing and completed ops)
• Waiver of subrogation on all policies
• Workers' comp certificate OR ADOL exemption certificate (Form WC-8)
• Signed W-9
• Executed subcontract with insurance exhibit

During the project:

• COI renewal tracking — most policies renew annually; flag 30-60 days before expiration
• Collect conditional lien waivers with each progress payment
• Collect unconditional waivers after payment clears

At closeout:

• Final unconditional lien waivers from all subs and suppliers
• Updated COI through the applicable statute of limitations period
• W-9s confirmed for 1099 filing

How PaperBoss Helps Alabama GCs

Tracking COI expirations, WC exemptions, lien waiver status, and W-9s across a roster of subs is a full-time job — most small GC offices spend 3 to 8 hours per week on exactly this kind of paperwork.

PaperBoss centralizes all of it: you upload the COI, we extract the coverage details, flag missing endorsements, and alert you before anything expires. When the ADOL WC exemption for your framing sub expires, you get a heads-up — not a gap in coverage discovered during an audit.

Start a free PaperBoss trial and get your Alabama sub compliance organized in under an hour.

Frequently Asked Questions

Is workers' comp required for all subcontractors in Alabama?

Alabama requires workers' comp only for employers with 5 or more employees. Subs with fewer than 5 employees are legally exempt — but GCs should still require WC coverage (or a valid ADOL exemption certificate) from every sub, because a GC can be held liable as the "statutory employer" if an uninsured worker is injured on their project.

What is the Alabama contractor license minimum for insurance?

The ASLBC requires at minimum $100,000 per occurrence / $300,000 aggregate GL for Limited licenses and $500,000/$1,000,000 for Unlimited licenses. Most GCs and project owners impose higher minimums (typically $1M/$2M) contractually.

How do I verify a sub's Alabama contractor license?

Use the ASLBC online lookup at aslbc.alabama.gov. For specialty trades (electrical, plumbing, HVAC), check the respective specialty board's website. Verify license status before work begins and again if the project spans a license renewal period.

What lien waiver form should I use in Alabama?

Alabama has no mandatory state form for lien waivers. Use a clearly drafted conditional waiver when making progress payments and an unconditional waiver once payment clears. Have your attorney review your waiver templates — vague language has been used to void waivers in Alabama courts.

Do I need to file a 1099 for Alabama subcontractors paid as an S-Corp?

Generally no — payments to corporations (including S-Corps and C-Corps) are exempt from 1099-NEC reporting. However, you still need a W-9 from the sub to confirm their entity type and EIN before you can make that determination.

What happens if I hire a sub in Alabama who doesn't have workers' comp?

If the sub has 5 or more employees and no WC coverage, they're violating Alabama law — and you may face liability as the statutory employer for any worker injuries. If the sub has fewer than 5 employees and hasn't filed a WC exemption, you're exposed to the same risk. Always collect proof of WC coverage or a valid ADOL exemption certificate (Form WC-8) before work starts.
