What Does a Home Inspector Do?
| Quick Answer: Home inspection professionals examine the condition of a residential property. They inspect various areas, including the structure, roof, plumbing, electrical, and HVAC systems. Home inspectors follow up each site visit with a detailed report documenting potential hazards, defects, and maintenance needs, which are critical at the offer stage. As such, home inspectors play a major role in closing a real estate transaction by providing buyers with the structural information needed to complete a deal. |
Home inspectors are highly valued given the significant role they play for home buyers and sellers in real estate transactions. It’s an attractive role for entrepreneurs who enjoy problem-solving, have an eye for detail, and are keen on construction and real estate.
According to a 2026 guide by an InterNACHI Master Inspector, home inspectors earn between $50,000 and $150,000 or more per year, with the national average home inspector salary landing around $62,000 to $75,000. As the real estate market continues to grow, the demand for skilled, professional home inspectors could increase, making it a promising career path for the foreseeable future.

What Is a Home Inspector?
A home inspector is a professional trained and certified to evaluate a residential property’s physical condition. They are usually hired when a property is under contract, where a buyer has made an offer that the seller has accepted, with the sale pending upon a successful home inspection. These sessions help identify major issues that affect the home’s value and may require costly repairs.
How Does a Home Inspection Work?
Home inspections are usually scheduled after an offer is accepted and take about 7-10 days, depending on the purchase agreement. Inspectors review a home’s structure according to standard guidelines set by the American Society of Home Inspectors (ASHI) or the International Association of Certified Home Inspectors (InterNACHI).
Inspectors generate a report within one to two days of the visit, documenting faults or defects and recommended actions. Buyers can use these reports to negotiate or reject a deal based on the findings. Inspectors may also include images to support their on-site observations.
What Do Home Inspectors Do: Roles and Responsibilities
A home inspector’s responsibilities include areas such as
1. Structural Elements
The inspector evaluates components, such as the foundation, walls, floors, and roofs, for structural integrity. They check for cracks in the foundation and signs of safety issues that may require major repairs.
2. Exterior
Home inspectors review siding, windows, doors, and other exterior components. These tasks include inspecting the drainage and elevation to determine potential issues like soil erosion or water damage. Inspectors may also examine detached structures like garden sheds, checking the condition of the shed base, which could reveal moisture issues or uneven settling.
3. Roof and Attic
A home visit includes leak inspections and assessing the condition of shingles, gutters, flashings, and chimneys. Inspectors also check attics for adequate ventilation and insulation, alongside potential water damage or rodent activity.
4. Plumbing System
Inspectors evaluate the home’s plumbing system, including drains, pipes, and water-heating equipment, checking for leaks, proper drainage, adequate water flow, and water heater condition.
5. Electrical System
Home inspections assess the electrical system, including panels, circuits, outlets, and light fixtures, to ensure they meet safety standards.
6. HVAC System
Inspectors thoroughly review heating, ventilation, and air conditioning (HVAC) systems, focusing on the condition of components like the furnace, air conditioning unit, ductwork, and thermostats.
7. Interior Features
Site inspections cover home interiors, including walls, ceilings, floors, windows, doors, and stairs for functionality and potential safety issues.
8. Insulation and Ventilation
Inspectors check for insulation and ventilation in key areas, such as the attic, basements, and crawl spaces, assessing energy efficiency and indoor air quality.
9. Fireplace and Chimney
If there’s a fireplace, inspectors will assess its overall structure, vent, and flue. A quality assessment also gets down to examining signs of creosote buildup, damper function, and the condition of chimney spark arrestors.
10. Basement and Garage
Basements and garages are inspected for signs of water intrusion, structural damage, or safety issues.
11. Safety Features
Inspectors verify the functionality of a home’s safety features, including smoke and carbon monoxide detectors and fire extinguishers.
How to Find a Good Home Inspector
Buyers should consider the following factors before hiring a home inspector to get the most thorough assessment:
- Certification and training: An official membership or qualification recognized by ASHI or InterNACHI, which requires inspectors to complete industry-approved training and follow standard practice guidelines.
- State licensing, if applicable: Buyers should check if home inspection state licensing rules apply by referring to the full listing found on official sites such as ASHI’s.
- Track record. Buyers can assess a home inspector’s reliability based on the number of completed inspections and the specifics of past assessments (i.e., that those properties are similar in age or type as theirs).
- A sample report. Past reports are effective proof of an inspector’s thoroughness and professionalism.
- Insurance. These policies should clearly include errors and omissions (E&O) coverage, which protects both parties if things go missing during a home inspection.
- Add-on services. Top home inspectors go beyond basic offerings to provide comprehensive assessments with specializations like radon, mold, or infrared testing.
What Is Not Covered in a Standard Home Inspection?
Professional home inspectors may provide optional, value-added services, giving buyers greater assurance while opening doors to additional income opportunities.
1. Radon Testing
Radon is a naturally occurring, radioactive gas that can be found in a home’s air or water supply and is a leading cause of lung cancer among nonsmokers. While regular home inspections don’t include radon testing, they are highly recommended every two years.
2. Mold Test
Home inspectors may run specialized mold tests to determine the type and extent of the infestation. In such cases, inspectors collect air or surface samples and typically partner with an accredited lab for thorough examination.
3. Infrared Scan
Specialized home inspectors may conduct infrared scans with thermal technology that detects issues invisible to the naked eye, like insulation gaps, electrical hazards, or hidden water leaks.
4. Sewer Scope Inspection
Home inspectors may use specialized scope cameras to inspect the interior of sewer lines, checking for damage such as loose debris, blockages, or pipe deterioration. Sewer scope inspections are usually recommended for older homes, where aging pipe systems are more prone to these issues.
5. Air and Water Quality Test
Top home inspectors may also go the extra mile to test a home’s air and water quality and potential contaminants. In such cases, inspectors collect and assess samples at an accredited lab to give buyers peace of mind.
Quality training is critical for inspectors who wish to offer extra services. A top franchise like WIN Home Inspection offers in-house training that equips inspectors with the right expertise and specialization to conduct the most thorough site visits for additional income opportunities across all seasons.
Becoming a Home Inspector: Franchising vs. Independent
Aspiring home inspectors may consider starting as an independent inspector, working for a company, or investing in a home inspection franchise. Each option has its pros and cons, although the franchise model often stands out as an appealing choice to first-time entrepreneurs.
A home inspection franchise offers a wide range of benefits, including established brand recognition, a proven business model, ongoing training, and marketing and operational support. As such, new business owners can drastically reduce the time it takes to launch their business and generate revenue.

Frequently Asked Questions
Does a home inspection take long?
Not usually. Most inspections take 2–4 hours for an average-sized single-family home. However, larger or older homes (due to worn parts that require more stringent inspections) can take longer.
What is the cost of a home inspection service?
Home inspections often cost anywhere between $300 and $500. But prices can vary widely based on a home’s size, age, and location. Additional services like radon or mold testing are priced separately.
Are home inspections and appraisals the same thing?
No. A home inspection looks at the physical condition of a home to identify defects or safety issues. On the other hand, an appraisal estimates the home’s market value. They serve different purposes: home inspections confirm a home’s safety and functionality before purchase, while appraisals are usually used for lending assessments.
Is it necessary for buyers to be present during home inspections?
No, buyer attendance isn’t strictly required, though it’s highly recommended. Being there lets buyers see the issues firsthand and address more pressing concerns with the inspector in real time, without waiting for the report.
What are some follow-ups for detected home inspection issues?
Home inspection reports give buyers the information needed to request repairs, negotiate a price reduction, or reject a contract (in more serious cases). The action taken ultimately depends on the terms outlined in the purchase agreement.
Conclusion
Home inspectors play essential roles during the real estate process for buyers and sellers. Their responsibilities include inspecting structural elements, checking various systems, evaluating exteriors and interiors, and assessing safety features.
For those aspiring to become home inspectors, starting a franchise, especially with a rapidly growing and nationally recognized organization like WIN Home Inspection, provides numerous benefits over going independent or working for a company.
