How to Start a Home Inspection Business in California

October 29, 2026

If you want to know how to start a home inspection business in California, the first fact to know is that the state does not issue a home inspector license. There is no state exam and no required education, which makes this one of the more accessible service businesses to enter. It does not mean the work is rule-free. The home inspection provisions of the Business and Professions Code apply to every inspector, certified or not, and your entity choice, contracts, and insurance all matter from the first day.

This guide covers what the law requires, what you need before your first inspection, and the order in which to handle the paperwork. Fees come from the California Secretary of State and other agencies. Where a figure may change or depends on your situation, the text tells you which agency to confirm it with.

Do You Need a License to Be a Home Inspector in California?

No. California does not license home inspectors, and there is no state exam or required course. The home inspection rules are not a licensing scheme, but they still bind you. Business and Professions Code sections 7195 to 7199 govern how inspectors perform and describe their work, whether or not they hold any certification. Several of these rules shape your contracts and marketing, so read them before you write your first agreement. Those rules are the core of most California home inspector requirements.

Certification from a trade association is optional. ASHI and InterNACHI are voluntary industry memberships that California does not require. Many real estate agents prefer certified inspectors, so membership can help with referrals. Check with each association directly about its current membership rules, training, and fees, because the state does not set them and they can change.

What the home inspection provisions cover

Under Business and Professions Code section 7195, a home inspection is a noninvasive physical examination. It is done for a fee in connection with a transfer of real property, and it examines the mechanical, electrical, or plumbing systems or the structural and essential components of a residential dwelling of one to four units. Its purpose is to identify material defects. If the property has a swimming pool or spa, the examination must also check which of the seven drowning prevention safety features listed in Health and Safety Code section 115922 the pool or spa has, and whether each one is in good repair and operable.

These rules affect your business most directly:

• Standard of care (BPC 7196). If you are not licensed as a general contractor, structural pest control operator, or architect, and not registered as a professional engineer, you must inspect with the care a reasonably prudent home inspector would use.
• Prohibited practices (BPC 7197). It is an unfair business practice to perform or offer repairs for an additional fee on a structure your company reported on in the past 12 months. It is also unfair to inspect a property in which you have a financial interest or an interest in the transfer, to pay or give anything of value to the owner, broker, or agent for referrals, or to accept an inspection whose fee depends on the conclusions, preestablished findings, or the close of escrow.
• Waivers and liability caps are void (BPC 7198). Contract language that waives the duty of care, or limits your liability to the cost of the report, has no effect.
• Four-year limit on suits (BPC 7199). A lawsuit for breach of duty arising from an inspection report must start within four years of the date of the inspection.

Keep your inspection agreement and your report inside these limits. A contract that tries to do what section 7198 forbids will not protect you, and it can make you look careless to a client or a court.

Materials and Tools You Will Need

Gather the following before you file anything. Items marked optional are not required by California law.

• A business name that meets the Secretary of State's naming rules, and a decision on whether you will operate as a sole proprietor, an LLC, or a corporation
• A business bank account and a basic bookkeeping system
• A federal employer identification number (EIN) from the IRS, which many businesses need for banking and payroll
• Errors and omissions insurance and general liability insurance, quoted by an insurance broker
• Workers' compensation insurance, required once you have an employee under Labor Code section 3700
• Inspection equipment such as a moisture meter, voltage tester, flashlight, ladder, and camera. Pricing varies widely, so compare several vendors yourself
• Inspection report software or a standard report template. Check each vendor's current pricing directly
• A written pre-inspection agreement that limits the scope of the inspection and follows sections 7196 to 7199
• A checklist that covers the systems and components in section 7195 and, for pools and spas, the seven safety features in Health and Safety Code section 115922
• Optional: ASHI or InterNACHI membership, or another certification

Step-by-Step: Starting Your Home Inspection Business

Step 1: Define your scope and rules before you form anything

Write down what you will inspect and what you will not do. Decide now that your company will not perform repairs on properties it reported on, will not pay for referrals, and will not inspect properties in which you have an interest. These decisions follow directly from section 7197, and they are far easier to build in at the start than to unwind later. Also decide whether you will describe yourself as a general contractor or a structural pest control operator. If you hold no license for that work, do not market it as a service you offer. The Contractors State License Board regulates contractor licensing if you ever plan to do that work.

Step 2: Choose a business structure

Many inspectors start as a sole proprietor using their own name, which requires no Secretary of State filing. If you want a separate entity to help limit personal exposure, the two common options are an LLC or a corporation. Each has different costs and tax treatment. Talk with a California attorney and a CPA before you choose, because the right answer depends on your income, your insurance, and whether you plan to hire.

If you form an LLC, note that California does not allow a domestic series LLC. An LLC also cannot render a licensed professional service, which is why professional corporations are used for licensed professions. Home inspection is not a state-licensed profession, but confirm with your attorney how that rule applies to your plans.

Step 3: Check and reserve your business name

Search the name on the Secretary of State's business search at https://bizfileonline.sos.ca.gov/search/business. An LLC name must contain 'limited liability company', 'L.L.C.', or 'LLC'. 'Limited' may be written 'Ltd.' and 'company' may be written 'Co.' The name may not contain 'bank', 'trust', 'trustee', 'incorporated', 'inc.', 'corporation', or 'corp.' A business called 'Sunrise Home Inspection Inc.' therefore cannot be formed as an LLC. A corporation name needs no designator. If you need time, you can reserve a name for $10 for 60 days, and the reservation cannot be renewed for consecutive periods. Details are at https://www.sos.ca.gov/business-programs/business-entities/name-availability.

Step 4: File your formation document

An LLC files Articles of Organization (Form LLC-1) with a $70 filing fee. A stock corporation files Articles of Incorporation for $100. File through bizfile Online at https://bizfileonline.sos.ca.gov/. Online filings are normally processed within about 5 business days or less, while paper filings take 10 or more business days. For faster service, the Secretary of State offers 24-hour processing for $350, same-day processing for $750 if received by 9:30 a.m., and 4-hour drop-off service for $500 with a precleared filing.

Your LLC or corporation must also keep an agent for service of process. That is either an individual who resides in California or a corporation that holds a Corporations Code 1505 certificate. An LLC must also keep an office in California, which need not be a place where business activity happens. Name your agent accurately, because legal papers will go to that agent.

Step 5: Register a fictitious business name if you need one

If you operate under any name other than your own legal name or your entity's exact name, you need a Fictitious Business Name Statement. File it with the County Clerk-Recorder in the county of your principal place of business within 40 days of starting to use the name. Publish it in a newspaper once a week for four weeks, and keep proof of publication. The statement expires after five years. The statutory fee is $10 plus $2 for each additional name or owner, but counties charge more and the newspaper publication fee is separate. Confirm your county's current fee with its clerk-recorder. The state rules are at https://www.sos.ca.gov/business-programs/business-entities/fictitious-business-names.

Step 6: Register with the right state agencies

California has no general state business license. The Secretary of State issues none, and the CDTFA seller's permit is not a business license. Your registrations depend on what you do.

• CDTFA: Fees for inspection services alone do not require a seller's permit. If you also sell taxable goods, check with the CDTFA at https://www.cdtfa.ca.gov/ before you start. The seller's permit is free. California sales tax is 7.25% statewide, and with district taxes, city rates run from 7.25% to 11.75%.
• Franchise Tax Board: Every LLC organized or registered in 2024 through 2026 owes the $800 minimum annual franchise tax from its first year. An LLC whose first taxable year begins in 2027, 2028, or 2029 pays $400 in year one under RTC 17941(g)(2), so confirm that figure with the FTB. An LLC also owes an LLC fee of $900, $2,500, $6,000, or $11,790 once California-source total income reaches $250,000, $500,000, $1,000,000, or $5,000,000. A newly incorporated or qualified corporation or S corporation owes no $800 minimum tax in its first taxable year.
• Employment Development Department: Register with the EDD once you have employees.

Step 7: Check your city and county

Most California cities charge a local business tax or require a registration certificate. Of the state's 483 cities, 445 report revenue from one, and there is no common formula, so the answer depends on the city. Counties license only regulated activities. Check the rules in every city where you will have an office or do regular work, and ask each city what applies to an inspection business before your first job.

Step 8: Set up California home inspection business insurance

Errors and omissions insurance and general liability insurance are commonly carried by home inspectors. Ask an insurance broker to quote both, and ask exactly what each policy covers and excludes, including how it handles claims that arrive years after an inspection. Workers' compensation becomes mandatory once you hire an employee under Labor Code section 3700. Premiums depend on your location, volume, and history, so get quotes rather than budgeting from someone else's numbers.

Step 9: Build your inspection and report process

Create a pre-inspection agreement that describes the scope, identifies areas you could not access, and stays within sections 7196 through 7199. Do not include waiver or liability-cap language, because section 7198 makes it void. Build a checklist that covers every system in section 7195. If you inspect pools or spas, add a checklist item for each of the seven drowning prevention safety features in Health and Safety Code section 115922, and record whether each one is present, in good repair, and operable. Keep photos and notes for every inspection, and ask an attorney how long to keep them, since the four-year limit in section 7199 bears on how long your records may matter.

Step 10: Set your marketing and referral rules

You can market to agents, brokers, and homeowners, but section 7197 bars you from paying or giving anything of value to the owner, broker, or agent for referrals. Anything of value counts, not just cash, so have an attorney review gifts, sponsorships, and referral arrangements before you use them. Also avoid any fee that depends on the conclusions, the findings, or the close of escrow.

Step 11: Calendar your ongoing compliance

An LLC files a Statement of Information (Form LLC-12) for $20 within 90 days of filing its articles, then every two years during the six-month window ending on the last day of the anniversary month. A corporation files a Statement of Information (Form SI-550) for $25 within 90 days, then every year. If you miss the deadline, the FTB assesses a $250 penalty after a Secretary of State notice. Also calendar your franchise tax, the five-year expiration of any fictitious business name, and your insurance renewals.

Tips and Common Mistakes to Avoid

• Assuming no license means no rules. The home inspection provisions bind every inspector. Read sections 7195 to 7199 in full before you write a contract.
• Putting waivers in your contract. Waiver and liability-cap language is void under section 7198, and it can signal to a client that you expect problems.
• Selling repairs after an inspection. Offering repairs for an additional fee on a structure your company reported on in the past 12 months crosses the line in section 7197.
• Tying your fee to the sale. A fee that depends on the conclusions, preestablished findings, or the close of escrow is prohibited.
• Using 'Inc.' or 'Corporation' in an LLC name. Those words are not allowed in an LLC name, so check before you pay for filings.
• Missing the fictitious business name steps. The 40-day filing window and the four weeks of newspaper publication are separate requirements. Confirm both deadlines with your county clerk-recorder.
• Forgetting the Statement of Information. A missed filing can bring a $250 penalty after a Secretary of State notice.
• Skipping your city's business tax. Most cities charge one, and the amount varies by city. Check before you take your first job.
• Assuming an inspection-only business needs a seller's permit. Fees for inspection services alone do not require one. Check with the CDTFA if you also sell products.
• Hiring without workers' compensation. Once you have an employee, Labor Code section 3700 requires coverage.
• Relying on one insurance quote. Compare coverage terms, exclusions, and claims handling, not just the premium.

What to Expect

A clear legal framework, a consistent contract, and a documented process may help you operate with fewer surprises. Many new inspectors find that a no-repairs, no-referral-payments policy and a standard report help build trust with agents and clients, though results vary by market. Filing on time and keeping insurance current may help you avoid penalties and gaps in coverage. Nothing in this guide guarantees any level of income, referral volume, or client satisfaction.
