How to Start a Home Inspection Business in Idaho: Is a License Required?

If you want to start a home inspection business in Idaho, the first question is usually whether you need a state license. The short answer is no. As of October 2026, Idaho has no state home inspector license. The Division of Occupational and Professional Licenses (DOPL) does not list a home inspector board among its boards and professions, and Idaho Code Title 54 has no home inspection chapter. Anyone may offer home inspections.

That does not mean you can skip preparation. Buyers, lenders and real estate agents look for specific credentials, insurance and paperwork before they refer work to an inspector. You still need to register your business, handle taxes and check local rules. This guide walks through each step in the order most new inspectors take them.

Is a Home Inspector License Required in Idaho?

No state home inspector license is required to perform inspections in Idaho. Three points matter here:

• No state board. DOPL does not license home inspectors. Its list of boards and professions has no home inspector entry.
• No statute. Idaho Code Title 54 has no home inspection chapter, so no state statute sets education, exam or licensing requirements for general home inspections.
• Specialty work is different. If you also test for radon, mold or other specialties, or perform trade work on systems you inspect, you may need a separate license or registration. Confirm that with DOPL before you advertise those services.

Rules can change, so check DOPL directly at (208) 334-3233 before you rely on this status. The rest of this guide assumes the current position holds.

What Buyers and Lenders Expect Instead

Because the state does not license inspectors, the market fills the gap. Most clients, agents and lenders expect some combination of the following. None is a legal requirement in Idaho, but each one affects whether you get referrals.

• National certification. ASHI and InterNACHI are the two credentials most often named in Idaho listings and referral lists.
• Examination. A state or national exam shows you have tested your knowledge of building systems and standards of practice.
• Continuing education. Ongoing training keeps your credential current and gives you a reason to update your report templates.

Use these credentials accurately. Idaho inspectors are not state licensed, so do not describe yourself as a "licensed home inspector." Name the credential you actually hold, such as an ASHI or InterNACHI membership or certification, and say where it came from.

Materials and Setup You Need Before You Start

Gather these items before you file anything. Most of them are needed at the first client booking.

• Your legal name and a decision on business structure, either a sole proprietorship or a limited liability company (LLC)
• An Idaho registered agent with a physical street address, if you form an LLC (P.O. boxes are not accepted)
• A federal Employer Identification Number (EIN) from the IRS
• An Idaho State Tax Commission TaxAccess Point (TAP) account
• The phone number and address of your city clerk, and of your county clerk if you work outside city limits
• Quotes for general liability and errors and omissions (E&O) insurance
• A written pre-inspection agreement, reviewed by an Idaho attorney
• Report software or a report template, plus your field equipment such as a flashlight, ladder, moisture meter and infrared camera
• A credential plan that names the certification, exam and continuing education you will complete

Step-by-Step: Starting a Home Inspection Business in Idaho

Step 1: Choose a Name and Business Structure

If you operate under your own legal name, you may not need to file a name with the state. If you want a business name such as "Treasure Valley Home Inspections," you will need an assumed business name filing (Step 3). If you form an LLC, the name must contain "limited liability company," "limited company," "LLC," "L.L.C.," "LC" or "L.C." Under Idaho Code 30-21-301, the name must also be distinguishable from names already on record with the Secretary of State. Entity-type words such as "LLC" do not count toward that test, so check the Secretary of State's business search before you commit to a name.

If you want to hold a name while you prepare paperwork, the Secretary of State takes a name reservation for 120 days for a $20 fee.

Step 2: Register Your LLC With the Idaho Secretary of State

An LLC is formed by filing a Certificate of Organization (Limited Liability Company). The filing fee is $100 when filed online through SOSBiz, and $120 on paper. Online filing is the faster route and is available at sosbiz.idaho.gov/forms/business/.

Processing is usually 7 to 10 days from the filing date. If you need faster service, the Secretary of State charges a $40 surcharge for evidence of filing within 8 working hours, or a $100 surcharge for same day service on filings submitted before 1:00 p.m. Mountain time. Current processing estimates are posted on the SOSBiz Processed Through Date page.

Every entity must keep a registered agent in Idaho. The agent needs a physical Idaho street address and must be available during normal business hours. You may act as your own registered agent if you have an Idaho address. An assumed business name cannot serve as a registered agent.

Step 3: File an Assumed Business Name if You Use a Trade Name

If you will operate under a name other than the owner or LLC name, file a Certificate of Assumed Business Name with the Idaho Secretary of State. This filing is statewide. It is not made with your county. The fee is $25 when filed online, or $45 on paper, which includes a $20 manual data entry surcharge. An assumed business name stays active until you cancel it and does not need renewal.

Your LLC name and your DBA are separate filings. Filing an LLC does not give you the right to advertise under a different name.

Step 4: Get an EIN From the IRS

Apply for a federal EIN from the Internal Revenue Service. You will need one to open a business bank account, file certain tax returns and, in many cases, to set up payroll if you later hire staff. Single-member LLCs and sole proprietors without employees can sometimes use other identifiers, so check with a CPA before you assume you can skip it.

Step 5: Open a TaxAccess Point (TAP) Account With the Idaho State Tax Commission

Register with the Idaho State Tax Commission at tax.idaho.gov and set up your TAP account. Your tax treatment depends on how the business is organized:

• Sole proprietor or default LLC. The business is a pass-through entity. Owners report Idaho income on their personal returns at the flat 5.3% rate.
• LLC filing as a partnership or S corporation. The entity owes the $10 permanent building fund tax.
• LLC taxed as a C corporation. The entity pays the 5.3% business income tax plus the $10 permanent building fund tax.

Idaho has no franchise tax and no LLC-specific annual state tax. The state sales tax rate is 6%, and there is no local sales tax outside voter-approved resort cities. Whether the 6% applies to your inspection fees or your written reports is a question to confirm with the Tax Commission before you invoice your first client.

Step 6: Check Your City and County Requirements

Idaho has no state general business license, and registering your entity is a registration, not a license. Counties issue no general business license. Local rules come from cities, and they vary. Some cities require a general business license for every business located inside city limits. Others license only specific activities. Your city clerk can tell you which applies to you. If you work outside city limits, ask the county clerk whether any activity-specific permit applies.

Business.Idaho.gov's Business Wizard at business.idaho.gov generates a checklist of agencies and permits for a specific activity. It is a useful starting point, but it does not replace a call to your city.

Step 7: Confirm Whether Your Specialties Need a Separate License

General home inspection does not require a state license in Idaho. Specialties may. Before you offer radon, mold, pest, septic or other testing, or any trade work on the systems you inspect, call DOPL at (208) 334-3233 and ask what license or registration applies. Idaho has no statewide general contractor license, and contractors register with the Idaho Contractors Board at DOPL. If you plan to do repair or installation work, confirm your registration status with DOPL first.

Step 8: Buy General Liability and E&O Insurance

Get quotes for both general liability and errors and omissions insurance before you accept your first paid inspection. General liability covers third-party injury and property damage claims. E&O covers claims that your report missed or misstated a defect. Ask each carrier what their policy excludes, and whether radon, mold or other specialty testing needs to be listed separately.

Step 9: Write a Pre-Inspection Agreement

Use a written agreement for every inspection. It should state the scope of the inspection, what is excluded, how and when the client pays, how the report is delivered, and how disputes are handled. Have an Idaho attorney review the template before you use it, and update the agreement whenever your scope changes.

Step 10: Set Up Your Credentials and Calendar

Choose your certification path, such as ASHI or InterNACHI, and schedule the exam and continuing education that come with it. Then set your annual report date. An LLC must file an annual report every year, beginning one year after formation. It is due before the end of the month in which the Certificate of Organization became effective. The annual report fee is $0, but the filing is still required, so put it on your calendar at the time you form the LLC.

Common Mistakes to Avoid

• Assuming no license means no rules. The absence of a state license does not cover radon, mold, trade work or city business licenses. Check each one.
• Using a trade name without filing it. Operating under a name other than your legal name or your LLC name requires an assumed business name filing.
• Listing a P.O. box as the registered agent address. The Secretary of State requires a physical Idaho street address.
• Calling yourself licensed. Idaho does not license home inspectors. Name the certification you hold instead.
• Skipping insurance. One missed defect with no E&O coverage can cost more than years of premiums.
• Using a generic contract without review. A template that does not match your scope can leave gaps in what you agreed to deliver.
• Forgetting the annual report. The fee is $0, but the filing is required every year.

Expected Results

A clean setup can put you in a position to take paid work with fewer surprises. Once your entity is registered, your tax account is open and your insurance and agreement are in place, you may be able to accept referrals more easily, because agents and lenders can see that your paperwork is in order. Your credential, reports and reviews will shape how much work you receive, and those results depend on your skill, your market and your local competition. No filing or credential guarantees a specific number of inspections or income.
