To become a home inspector in Minnesota, you complete a training program, pass the National Home Inspector Examination, buy errors and omissions and general liability insurance, register a business with the Secretary of State, and join a national certifying association like ASHI or InterNACHI. Minnesota is not one of the roughly 35 states that license home inspectors, so there is no state board, no mandatory education hours, and no state exam.1American Society of Home Inspectors, Inc. Home Inspection Requirements for Minnesota What fills that gap is the market: real estate agents, lenders, and buyers decide who they trust, and most of them will not hire an inspector who lacks national certification and proof of insurance.
One state credential does apply if you plan to test for radon, and that catches a lot of new inspectors off guard. More on that below.
Complete a Home Inspection Training Program
Because Minnesota sets no minimum training hours, program length is up to you and the school. Hennepin Technical College offers a 200-hour certificate covering heating and cooling, plumbing, electrical, roofing, structural components, insulation, and interior elements.2Hennepin Technical College. Home Inspection Certificate Minnesota State College Southeast runs a comparable program built around 11 modules that leads into the national certification exams.3Minnesota State College Southeast. Home Inspection Certificate
When you compare programs, look for supervised field inspections rather than pure classroom time. Reading about knob-and-tube wiring is not the same as tracing it in a dark crawlspace, and the mock inspections are what make the exam and your first paid jobs manageable. Budget roughly $2,000 to $3,000 for a solid program.
Pass the National Home Inspector Examination
The National Home Inspector Examination is the competency benchmark the industry uses in place of a state test. It runs four hours and covers every major residential system. The fee is $225 per attempt and is nonrefundable.4National Home Inspector Examination. Test Policies
Eligibility to sit the NHIE varies by state. Licensed states usually require a set number of approved education hours first. Minnesota imposes no such prerequisite, so your route in depends on the training program you complete and the association you plan to join. Both ASHI and InterNACHI accept the NHIE within their certification pathways.
Get a Minnesota Radon Measurement License If You Plan to Test for Radon
Minnesota does not license home inspectors, but it does license radon professionals, and radon testing is a common add-on that clients ask for. Anyone who places or retrieves radon test devices in a building they do not own or lease needs a Measurement Professional License from the Minnesota Department of Health, under the Minnesota Radon Licensing Act at Minnesota Statutes 144.4961.5MN Dept. of Health. Licensing for Radon Professionals
The annual fee is $150 for a measurement-only license, or $250 for a mitigation license that also covers measurement.5MN Dept. of Health. Licensing for Radon Professionals You have to complete an MDH-approved initial training course and pass a radon measurement examination before you can apply. Renewals require eight hours of continuing education within 11 months after expiration.6Legal Information Institute. Minnesota Rules 4620.7200 – Radon Measurement Professional License
Performing radon testing without this license violates state law. It is the one area where a Minnesota home inspector can face direct regulatory consequences, so treat it accordingly.
Lead-Based Paint: Only If You Offer It
A standard home inspection that simply notes visible peeling paint does not trigger any lead certification. If you market lead inspection or lead risk assessment as a service in pre-1978 housing, schools, child-occupied facilities, or play areas, your firm has to be certified by the Minnesota Department of Health, which runs the EPA-authorized program in Minnesota. Renovation work in pre-1978 homes falls under the federal EPA’s Renovation, Repair, and Painting Rule instead.7MN.gov. Lead Firm Certification
Line Up Your Insurance
In an unlicensed market, your insurance policies do double duty: they protect your assets and they signal to referral partners that you operate professionally. Two policies are essential from day one.
Errors and Omissions
Errors and omissions coverage pays when you miss something. If you fail to report a failing furnace or overlook water damage in a crawlspace and the buyer finds it after closing, E&O responds to the claim. Most agencies will not refer clients to an inspector without it, and many inspection agreements require it in writing. Combined E&O and general liability premiums typically run $1,500 to $3,500 per year depending on limits, deductible, and inspection volume.
General Liability
General liability covers the physical side of the job: the dented gutter, the cracked attic-hatch tile, the client who trips on your equipment. Industry norms call for at least $1 million in coverage. New inspectors performing modest volume usually sit at the lower end of that combined premium range.
Workers’ Compensation
If you operate as a solo inspector with no employees, Minnesota does not require workers’ compensation insurance.8MN.gov. Workers’ Compensation Insurance It becomes mandatory the moment you hire anyone, including a part-time assistant.
Register Your Business
Every home inspection business has to register with the Minnesota Secretary of State.9Office of the Minnesota Secretary of State. How to Register Your Business Most new inspectors choose between a sole proprietorship and an LLC.
Forming an LLC costs $155 online or $135 by mail. A sole proprietorship in your own legal name needs no separate filing, but a sole proprietorship operating under any other name requires a Certificate of Assumed Name at $50 online or $30 by mail.10Office of the Minnesota Secretary of State. Business Filing and Certification Fee Schedule The LLC is worth the extra cost for most inspectors because it separates personal assets from business liabilities, which matters in a profession where a missed defect can generate a lawsuit years later.
Once the entity exists, apply for a free Employer Identification Number from the IRS. You will need it to file tax returns, open a business bank account, and hire employees later.11Internal Revenue Service. Get an Employer Identification Number Then register with the Minnesota Department of Revenue for a Minnesota Tax ID Number, which covers state income tax withholding and sales tax obligations.12Minnesota Department of Revenue. Registering Your Business You can register online or by calling 651-282-5225. Some cities also require a local business license or permit, so check with your city clerk before you start taking jobs.
Join a National Association
Without state licensing, professional association membership functions as your working credential. The two dominant organizations are the American Society of Home Inspectors and the International Association of Certified Home Inspectors. Both require proof that you have passed the NHIE or their own equivalent exam, and both grant “Certified” designations that real estate professionals recognize.
InterNACHI’s annual membership fee is $599 starting in 2026. ASHI uses a tiered structure based on experience and inspection count, with annual dues in a similar range. Membership also comes with continuing education, standards of practice, and marketing resources that help new inspectors build credibility faster than working alone.
Joining also binds you to a code of ethics. ASHI’s code, for instance, bars inspectors from inspecting property they have a financial interest in, from accepting referral fees from real estate agents, and from being paid to recommend contractors.13American Society of Home Inspectors. Code of Ethics Since your association membership is effectively your license in Minnesota, an ethics violation that costs you membership costs you your professional standing.
What It Costs to Get Started
Adding up the pieces gives a realistic picture of first-year costs before you earn any revenue:
- Training program: roughly $2,000 to $3,000
- NHIE exam fee: $225 per attempt
- Business registration: $50 to $155 depending on structure and filing method
- Insurance (E&O and general liability): $1,500 to $3,500 annually
- Equipment: $1,500 to $3,000 for a complete starter kit
- Reporting software: $400 to $900 initial cost, plus subscription fees
- Association membership: roughly $500 to $600 annually
- Radon measurement license: $150 annually, plus training course costs
A reasonable first-year budget lands between $6,500 and $11,000. That is less than in licensed states, where mandatory pre-licensing education alone can run $5,000 or more, but the responsibility for verifying your own competence sits entirely with you.
