Nebraska Mold Rules and Contractor Registration, Explained

This page exists because almost nobody in this trade explains it, and it changes how you should hire. Short version: Nebraska does not license mold remediation. There is no state mold credential, no state clearance standard, and no state agency that inspects mold work. What the state does have is a contractor registration system, and that is a different thing from a license.

Verify all of this yourself. Rules change, and you should not take a website's word for anything that affects a contract you are about to sign.

1. Nebraska has no mold license

A handful of states run mold licensing programs. Nebraska is not one of them. The Nebraska Department of Health and Human Services publishes guidance for property owners on mold and mold cleanup, but the state does not license the mold industry, does not require specific training, and does not prescribe a required procedure for remediation work.

The industry standard most reputable contractors reference is IICRC S520, a private consensus standard for mold remediation. It is not law in Nebraska. A contractor following it is following a respected industry practice voluntarily, which is a good sign, but it is not a state requirement and it is not something a state agency checks.

What this means for you

The vetting burden is yours. There is no board to complain to about mold work quality specifically, and no state credential that separates a competent contractor from an incompetent one. Ask about training. Ask for a sample report. Ask which lab they use for samples. Ask for references on similar jobs. Get everything in writing.

2. Nebraska has no general contractor license either

This surprises people who have moved here from other states. Nebraska does not issue a statewide general contractor license. What the state requires is registration with the Nebraska Department of Labor under the Contractor Registration Act, found at Neb. Rev. Stat. sections 48-2101 through 48-2117.

Key points about that registration, as published by the Department of Labor:

• Contractors and subcontractors doing business in Nebraska are required to register with the Nebraska Department of Labor before performing construction work.
• Registration is not a competency exam. There is no trade test, no experience minimum and no surety bond requirement at the state level.
• The registration fee has been $25 annually, renewed on the anniversary date.
• Contractors with one or more employees must provide a current workers' compensation certificate of insurance with the Department of Labor listed as certificate holder. If that coverage lapses, the contractor is removed from the registered list until it is restored.
• There is a statutory exemption for property owners working on their own property, and for contractors earning less than $5,000 annually from construction services.
• The Department of Labor maintains a public database of registered contractors, accessible on its website.

3. The City of Lincoln has its own requirements

State registration is the floor, not the ceiling. Lincoln and Lancaster County run their own permitting and trade requirements through the City of Lincoln Building and Safety division, part of Planning and Development Services. Specific trades, including electrical, plumbing and mechanical work, go through city-level requirements that can include examinations, bonds and insurance minimums well beyond what the state asks for. Permits are handled through the city's online permitting portal.

Why this matters for a mold job: mold remediation itself is not a permitted trade, but the repair work that follows often is. If your job involves reworking plumbing, electrical, mechanical systems or structural elements, permits and city trade requirements come into play. Ask the contractor who is pulling the permit and confirm it is actually being pulled.

4. Insurance is a separate question entirely

Registration is not insurance. Ask any contractor for a certificate of insurance showing general liability coverage and workers' compensation, and ask for it to be sent directly from their agent rather than as a photocopy. Verify the policy is current. This is standard practice and no legitimate contractor will be offended by the request.

5. Federal rules still apply on older homes

If your property was built before 1978 and the work will disturb painted surfaces, the federal EPA Renovation, Repair and Painting rule applies and the firm doing the work needs the appropriate federal credential for lead-safe work practices. Lincoln has a very large stock of pre-1978 housing, particularly across Near South, Woods Park, University Place, Havelock, College View and the Bottoms neighborhoods, so this comes up often. Nebraska DHHS administers lead hazard programs in the state.

6. Nebraska guidance on cleanup scale

State health guidance points to roughly ten square feet as a practical dividing line. Below that, a property owner can generally handle cleanup themselves with gloves, goggles and an N-95 respirator, and only if they do not have allergy, asthma or immune concerns. Above that, or where growth is inside wall cavities, in the HVAC system, or associated with sewage or contaminated water, professional containment is appropriate.

7. Renting or landlord situations

Nebraska handles mold disputes between landlords and tenants through general habitability and property condition law rather than a dedicated mold statute. Responsibility usually turns on cause: building failures such as leaks, roof problems or ventilation defects generally point to the landlord, while damage tied to a tenant's own conduct points the other way. Written notice and documentation matter enormously in these disputes. Photograph everything and put requests in writing.
