How to Start a Home Inspection Business

    Home InspectionBy the Home Nexio Editorial Team2 min read

    Nearly every home sale in the US involves a home inspection, which makes inspectors a near-permanent fixture in the real estate transaction process. Starting an inspection business is genuinely more accessible than many licensed trades, but it still requires real training, certification, insurance, and — critically — a referral network with real estate agents, since that's where most inspection business comes from.

    Step 1: Get Trained

    Whether or not your state requires a specific number of training hours, get real training before your first paid inspection. The two major national certifying bodies — ASHI (American Society of Home Inspectors) and InterNACHI (International Association of Certified Home Inspectors) — both offer structured training programs, and most state licensing requirements (where they exist) accept coursework from approved providers aligned with one or both organizations. See our ASHI vs. InterNACHI guide for how the two compare.

    Step 2: Confirm Your State's Licensing Requirement

    Home inspector licensing requirements vary significantly by state — most states license inspectors with some combination of training hours, a supervised/mentored inspection count, and a state or national exam, but a smaller number of states have no state-level licensing requirement for home inspectors at all. Confirm the current rule directly with your state's licensing board (often housed under a general contractor licensing division or its own dedicated board) before planning your timeline, since this genuinely changes your path.

    Step 3: Get Insured

    General liability insurance is standard, and most inspectors also carry errors & omissions (E&O) coverage specifically — since the real risk in home inspection isn't physical injury on the job, it's a missed defect that a buyer later claims you should have caught. E&O coverage is what actually protects you from that kind of claim, and many states that license inspectors require it as a condition of licensure.

    Step 4: Get Your Equipment

    A home inspection business needs real equipment — moisture meters, outlet testers, a good ladder, often a thermal imaging camera — see our full equipment checklist for what's genuinely necessary versus optional for a new inspector.

    Step 5: Set Your Pricing

    Inspection pricing is typically based on the home's square footage and age, with add-ons for services like radon testing, termite inspection, or sewer scope. See our pricing guide before quoting your first job.

    Step 6: Build Realtor Relationships

    Most inspection business comes through buyer's agents, not direct buyer searches. Buyers overwhelmingly choose whichever inspector their agent recommends, which makes agent relationships the single highest-leverage marketing channel in this business. See our client acquisition guide for how to build those relationships from scratch.

    What Makes a Good Inspector Report Stand Out

    A clear, well-organized, photo-documented report — delivered quickly — does more for your referral business than almost anything else. Agents want their buyers to understand what they're reading without panicking over minor issues, and a report that's thorough but readable builds the kind of trust that generates repeat referrals.

    Frequently Asked Questions

    Do I need a license to be a home inspector?

    It depends on your state. Most states license home inspectors, typically requiring a set number of training hours, a supervised number of inspections, and passing an exam -- but a smaller number of states have no state-level licensing requirement at all for home inspectors. Confirm the current rule with your state's licensing board; see our full certification guide for how to check.

    How long does it take to become a home inspector?

    Timelines vary by state and training path, but most people complete required coursework and any state-mandated supervised inspections in roughly 3-6 months, with some faster-track programs available in states with lighter requirements.

    Is home inspection a good business to start with no construction background?

    It's more accessible than a licensed trade like electrical or plumbing, but a working knowledge of how homes are built and what commonly fails still matters -- many successful inspectors come from construction, real estate, or engineering backgrounds, though formal training programs are designed to bring newcomers up to speed.

    How much can a new home inspector realistically earn?

    Earnings scale directly with inspection volume, which depends heavily on how many realtor referral relationships you've built. Established inspectors in active markets can build a strong full-time income, but the first year is typically slower while you build those referral relationships.
