How to Start a Home Inspection Business in Arizona: Board of Technical Registration License

If you want to get paid to inspect homes in Arizona, the credential you need comes from the Arizona Board of Technical Registration (BTR). No county or city issues a home inspector license. The state defines a home inspector in A.R.S. 32-101, and the certification rules sit in Arizona Administrative Code R4-30-247. This guide covers the certification steps in the order you will need them, then the business setup that follows.

This article is informational, not legal or tax advice. Rules and fees change, so confirm every figure on the agency page named in each step before you pay or file. For complex situations, such as combining inspections with repair work or forming a multi-owner business, talk with a licensed Arizona attorney or CPA.

What You Will Need Before You Start

• A date for the National Home Inspector Examination (NHIE), passed within 2 years before you apply
• A school offering the 84 hours of classroom training, licensed by the Arizona State Board for Private Postsecondary Education or approved by an accreditor the rules recognize
• A certified home inspector willing to supervise your 30 parallel inspections, plus a written log
• Fingerprints and BTR application fees
• A business name and address, plus an Arizona statutory agent if you form an LLC
• Insurance quotes, since you should confirm whether BTR requires coverage

Step 1: Confirm Your Services Fit the State Definition

Read the home inspector definition in A.R.S. 32-101, then compare it against the services you plan to sell. If you expect to offer repairs, remodeling estimates, or other work on the homes you inspect, check with BTR before you advertise those services. The home inspector certification covers inspection work. Contracting work falls under a different agency (see Step 10).

Step 2: Pass the National Home Inspector Examination

R4-30-247 requires you to pass the NHIE within 2 years before you apply to BTR. Schedule the exam with your application timeline in mind. A pass older than that window does not satisfy the rule, so you would need to retake the exam. Confirm the exam fee and scheduling process with the exam provider.

Step 3: Complete 84 Hours of Approved Training

R4-30-247 requires 84 hours of classroom training. Before you pay any school, confirm that it is licensed by the Arizona State Board for Private Postsecondary Education or approved by a recognized accreditor. Ask for its license or approval number and verify it yourself. The training must cover these subjects:

• Structural systems and exterior components
• Roofing, plumbing, heating, and cooling
• Electrical systems, insulation, and ventilation
• Interiors and fireplaces
• Pools and spas
• Professional practice

Pool and spa inspection is optional under R4-30-247. You may leave it out of your services, but your contracts, reports, and advertising should match what you actually inspect. Tuition varies by school, so compare total cost, including materials and exam prep, before you enroll.

Step 4: Log 30 Parallel Inspections

R4-30-247 requires 30 parallel inspections alongside a supervising certified inspector, with each one logged. Treat these as practice on real houses, not a box to tick. Ask your supervisor to walk the property with you, explain findings as you go, and sign the log.

Record each inspection as you complete it: the date, the property address, your supervisor's name, and a short note on what you did. Use the log format BTR provides, and check whether it wants a signature on each entry or on the full log. Logging inspections you did not take part in is a mistake that can derail your application.

Step 5: Submit Your Application, Fingerprints, and Fees

BTR's 2024 application packet lists $175 in total: a $100 application fee plus a $75 initial registration fee. That figure may have changed. Check btr.az.gov for current fees before you send money, and confirm the fingerprint process and cost with BTR as well.

Assemble the full package before you send it: your exam result, training certificate, signed parallel inspection log, fingerprints, and payment. An incomplete application can delay your certification. Keep copies of everything you submit.

Step 6: Build Your Reports Around the Standards of Practice

Once certified, you inspect under the BTR Standards of Professional Practice in R4-30-301. Build your checklist and report template around those standards from your first job. Reports that skip required areas leave gaps for you and your clients, so review the standards at least once a year.

Step 7: Check Insurance Requirements

Ask BTR directly whether it requires insurance for certification. Whatever the answer, get quotes for general liability and errors and omissions coverage before your first paid inspection. Bring your entity details to the quote conversation, since the structure you choose can affect the cost.

Step 8: Form Your Business Entity

Two common choices are an LLC and a for-profit corporation. The Arizona Corporation Commission files both, through the Arizona Business Center. Start at the Corporations Division page.

Forming an LLC

Articles of Organization (Form L010, with instructions L010i) cost $50 to file. Expedited review adds $35, for $85 total. Accelerated service is a further fee on top of the filing fee: $100 for next day (received by 5pm), $200 for same day (received by 10am), or $400 for two hour service (available 8am to 3pm). Accelerated service guarantees examination within the stated window, not approval.

As posted on December 29, 2025, regular processing takes about 9 to 11 business days and expedited processing takes 2 to 4 business days. Check the current processing sheet before you file.

Your name must include the words limited liability company or limited company, or the abbreviations L.L.C., L.C., LLC or LC. It must not include association, corporation, incorporated, or an abbreviation of those words. Search the Business Search tool before you choose a name. A name reservation holds it for 120 days for $10.

Every LLC needs a statutory agent who accepts legal papers and official Commission notices. An individual agent must be a permanent, full-time Arizona resident with a permanent, full-time physical or street address in Arizona. An entity can serve, including a foreign corporation or LLC authorized to transact business in Arizona, but an LLC cannot be its own agent. The agent must accept in writing on Statutory Agent Acceptance form M002. Keep a valid agent on record at all times, because lapsing risks administrative dissolution under A.R.S. 29-3708. Changing the agent or principal address costs $5 for an LLC.

An LLC must publish notice unless its statutory agent's county is Maricopa or Pima. If your agent is elsewhere, plan for publication as part of formation and confirm the details with the Commission.

Arizona LLCs file no annual report, and the Commission charges no LLC franchise tax or annual report fee. Income passes through to members, who pay Arizona's flat 2.5% individual income tax. An LLC that elects corporate treatment pays the corporate rate below.

Forming a corporation

Articles of Incorporation for a for-profit corporation cost $60 and must be filed with a Certificate of Disclosure. A for-profit corporation files an annual report each year for $45, due in its anniversary month (A.R.S. 10-1622). Corporate income tax is 4.9% of net income or $50, whichever is greater (A.R.S. 43-1111).

Step 9: Register a Trade Name if You Need One

If you will operate under a name other than your legal entity name, register a trade name with the Arizona Secretary of State's Business Services Division at azsos.gov/business/tntm. Trade name registration is optional and separate from the Corporation Commission filing. Confirm the current fee on that page.

Step 10: Handle Tax and Local Licensing

Arizona has no general state business license. Most businesses with taxable activity need a Transaction Privilege Tax (TPT) license from the Arizona Department of Revenue, which costs $12 per location. Ask the Department whether your services fall under a taxable classification before you assume you need one, and review the TPT license page before you apply.

Counties issue no general business license. Cities and towns often require their own business or TPT license on top of the state license, so check with your city or town clerk before you open.

The Registrar of Contractors licenses contractors, not home inspectors. If you plan to perform repairs or construction work on the properties you inspect, ask the Registrar whether that work needs a contractor license before you offer it.

Common Mistakes to Avoid

• Looking for a county or city home inspector license. BTR certifies home inspectors in Arizona.
• Letting your NHIE pass age out. It must fall within 2 years before you apply.
• Enrolling in a school you have not verified as licensed or approved.
• Logging parallel inspections you did not take part in.
• Choosing an LLC name before searching the Business Search tool.
• Forgetting that an LLC needs a statutory agent who accepted the appointment in writing.
• Assuming no publication step applies when your agent is outside Maricopa and Pima counties.
• Skipping the TPT question, or assuming your city does not require its own license.
• Offering repair work under an inspection certification without checking the Registrar of Contractors.
• Treating the $175 BTR figure as current. It comes from the 2024 packet.

Expected Results

Completing these steps may put you in a position to accept paid inspections once BTR issues your certification. Many new inspectors find that their parallel inspections give them a checklist and report style they can reuse, which may make early jobs easier. Results depend on your training, your local market, and your business decisions, and no outcome is guaranteed. Expect the state steps to take longer than you planned, and treat any timeline you find online as an estimate until BTR confirms it.
