How to Start a Home Inspection Business in Oklahoma: CIB License, $280 to Start, $150 Renewal

October 29, 2026

To inspect homes for pay in Oklahoma, you need a home inspector license from the Construction Industries Board (CIB). The license is issued under the Home Inspection Licensing Act (59 O.S. 858-621 et seq.) and the CIB rules in OAC 158:70. The CIB application fee ($30) and license fee ($250) total $280. That is not your full startup cost. The exam, training, insurance and business formation all add to it, and this guide covers each one in the order you will likely need them.

This article is informational content, not legal or tax advice. Fees and rules change, so confirm every figure with the agency named before you spend money.

What You Need Before You Start

Gather these items before you file anything:

• 90 hours of training from a Committee-approved school
• A $200 exam fee, paid to PSI, the CIB's exam vendor
• General liability insurance with a combined single limit of at least $50,000, naming the CIB as certificate holder
• The CIB application fee ($30) and license fee ($250)
• If you form an LLC, a $100 filing fee for Articles of Organization
• Optional: a $10 name reservation, which holds a name for 60 days
• A registered agent with a physical Oklahoma street address (no PO box)
• A federal Employer Identification Number (EIN) from the IRS, if your structure requires one
• A calendar reminder for your license renewal date

Step 1: Read the Act and the CIB Rules Yourself

Before you pay for training, read the Home Inspection Licensing Act and OAC 158:70. The statute and rules set the training hours, exam, insurance, continuing education and marking requirements that this guide summarizes. Summaries can lag behind rule changes, so the primary text controls. Ask the CIB office for the current version if you cannot locate it online.

Step 2: Complete 90 Hours of Approved Training

Oklahoma requires 90 hours of training at a school approved by the CIB's committee. A course that covers home inspection is not automatically approved, so do not assume it counts. Ask each school for written confirmation that it is Committee-approved, and ask for a certificate of completion that shows your hours. You will need that certificate to apply.

Tip: Get tuition quotes from at least two approved schools. Tuition varies, and the cheapest option is not always the one with the most hands-on instruction.

Common mistake: Enrolling in a course that is not on the approved list, then discovering the hours will not count.

Step 3: Buy the Required Insurance

You must carry general liability insurance with a combined single limit of at least $50,000. The CIB must be named as certificate holder, and the policy must give the CIB 30 days' notice of cancellation. Ask your insurance agent for a certificate of insurance written to those terms, not a generic certificate. Premiums vary by carrier, coverage and location, so compare more than one quote.

Common mistake: Buying a policy with the right limit but without the CIB named as certificate holder, then waiting weeks for a corrected certificate.

Step 4: Register for and Pass the PSI Exam

The licensing exam is a PSI exam arranged through the CIB. It is not the National Home Inspector Examination (NHIE), so do not register through NHIE. The exam fee is $200. If you do not pass, you can retake the exam after 30 days.

Tip: Study the rules in OAC 158:70 alongside your training materials. Exam questions can turn on regulatory details that a general home inspection course may gloss over.

Step 5: Form Your Business Entity

Many inspectors form an LLC to separate business liabilities from personal assets. Whether that structure fits your situation is a question for an attorney or CPA. Oklahoma has no general state business license, so your entity filing goes to the Oklahoma Secretary of State.

LLC: File Articles of Organization for $100 through the Secretary of State's Business Filing Department at https://www.sos.ok.gov/business/default.aspx. Your name must include limited liability company, limited company, LLC, LC, L.L.C. or L.C. (Ltd. and Co. are acceptable abbreviations for limited and company). It must be distinguishable from other entity, trade and reserved names on file, current or within the last three years. Search names at the Secretary of State business search, and reserve one for $10 for 60 days at the name availability page.

The LLC annual certificate costs $25 and is due on the anniversary of your filing. You get a 60-day grace period. The statute carries no late fee, but an LLC that misses the 60 days stops being in good standing. Reinstatement has no fee of its own, but you must file every delinquent annual certificate.

Corporation: A Certificate of Incorporation costs 1/10 of 1% of authorized capital stock, with a $50 minimum. Shares without par value count as $50 each, so 10,000 no-par shares carry a $500 fee. Domestic for-profit corporations file no annual certificate with the Secretary of State.

Registered agent: Every LLC and corporation must keep a registered agent at a physical Oklahoma street address that is open during business hours to accept legal papers. Changing the agent or office costs $25.

Trade name: If you operate under a name other than your legal name or entity name, file a Trade Name Report with the Secretary of State for $25. The filing goes to the state, not the county, and no newspaper publication is required. See the Secretary of State filings page.

Step 6: Submit Your CIB Application and Pay $280

Submit your application with the required fees: $30 application plus $250 license, for a total of $280. Include your training certificate, exam result and insurance certificate. This guide does not list a CIB processing time, so confirm the current application form, required attachments and turnaround with the CIB before you submit.

If you already hold a home inspector license from another state and want a reciprocity license, the fee is $50. Confirm your eligibility with the CIB before you apply.

Common mistake: Accepting paid inspections before the license is issued. Wait until you hold the license in hand or in writing from the CIB.

Step 7: Set Up Your Tax Registrations

Oklahoma's state sales tax rate is 4.5%. Cities and counties add their own sales taxes, which the Oklahoma Tax Commission (OTC) collects on the same return, so combined rates run from about 8.25% to above 10%. Register with the OTC through OkTAP at the OkTAP business registration page if you collect sales tax or withhold tax from employees. A sales tax permit costs $20 for three years.

Do not assume your inspection fees are exempt or taxable. Ask the OTC, through its main tax website, whether your services or any products you sell, such as add-on reports, are subject to sales tax. A CPA can help you set up bookkeeping that separates taxable and nontaxable receipts.

Step 8: Check City and County Requirements

Oklahoma has no general state business license, and the state does not require one from you. Cities are different. Some charge a general or occupational license, including Bartlesville, Yukon, Sapulpa, Bixby, Tahlequah and Mustang. Oklahoma City, Tulsa and Lawton license only specific activity types. Counties issue no business licenses. Oklahoma County and Tulsa County run zoning and building permits in unincorporated areas only.

Call your city clerk or check the city website and ask whether any general, occupational or home-related license applies to your business. Do not assume that because your city is not listed here, it has no requirement.

Step 9: Follow the License Display Rules

Your license number must appear on stationery, business cards, bids, estimates, printed and electronic advertising, decals and yard signs. Build those templates before your first marketing push, and check your website, social media profiles and vehicle decals against the list.

Common mistake: Printing a truck decal with your business name and phone number but leaving off the license number.

Step 10: Plan for Renewal and Continuing Education

A home inspector license expires 12 months after issuance and carries a 30-day renewal window. Confirm with the CIB exactly how that window applies to your license so you do not lapse. Renewal costs $150.

• Continuing education: 8 clock hours each year from Committee-approved courses. No more than 2 of those hours may cover ancillary systems.
• Expired over a year: You must re-earn the license by exam.
• Reactivation: $50. Confirm with the CIB when reactivation applies to your situation.
• LLC annual certificate: $25 each year on your formation anniversary, with the 60-day grace period described in Step 5.

Under SB 1732, fees rise on July 1, 2028. The license fee goes to $400, the renewal fee to $240 and the reciprocity fee to $80. If you plan to renew after that date, budget for the higher amounts.

Training, insurance and exam costs are the largest variables. Use the table as a checklist, and confirm each fee with the agency listed before you budget.

Common Mistakes to Avoid

• Treating $280 as your total startup cost. The CIB fees are only one part of the budget.
• Registering through NHIE. Oklahoma uses a PSI exam arranged through the CIB.
• Buying insurance without the CIB as certificate holder. Ask for the certificate in the exact terms the CIB requires.
• Filing a DBA with the county. A Trade Name Report goes to the Secretary of State.
• Missing the LLC annual certificate. After 60 days past the anniversary, the LLC is no longer in good standing.
• Letting the license lapse for more than a year. You will need to re-earn it by exam.
• Leaving the license number off ads and vehicles. The number must appear on all listed materials.

What to Expect Once You Are Licensed

A license allows you to perform paid home inspections under Oklahoma's rules. It does not guarantee clients, referrals or any level of income. Results depend on local demand, competition, your pricing, your reputation and how you market your services. Many new inspectors spend their first months building relationships with agents, lenders and property managers, but outcomes vary widely.

For free business guidance, the Oklahoma Small Business Development Center network can help you plan, and the SBA's Oklahoma district page lists local resources.

Next Steps

Start with the Act and OAC 158:70, choose an approved training school, and get insurance quotes that meet the CIB's terms. Then form your entity, file your registrations, and submit your CIB application when you have every document in hand.
