Indiana Home Inspection Response Guide for Real Estate Agents

Indiana Inspection-Response Overview

Indiana law establishes minimum requirements for home-inspection reports. When applicable, the report must identify inspected systems or components that the inspector believes are significantly deficient or near the end of their service life, explain the reason unless self-evident, and include a recommendation to remedy or monitor the deficiency. The report must also identify systems or components required by the standards that were not inspected and explain why they were not inspected.[1]

Indiana’s minimum standards also establish important boundaries around a home inspector’s required work. Inspectors are not required to determine the cause of a condition or deficiency; the methods, materials, or costs of corrections; future conditions or failures; compliance with codes, regulations, laws, or ordinances; market value or marketability; or whether purchasing the property is advisable.[1]

The Indiana Home Inspectors Licensing Board’s standards also state that the standards are not technically exhaustive and do not identify concealed conditions or latent defects.[1]

For the post-inspection workflow, the inspection report remains the source for the inspector’s findings and professional opinions. Repair-cost research, specialty evaluations, vendor selection, and transaction decisions are separate downstream activities.

Transaction-specific deadlines, notices, and remedies should be reviewed against the executed agreement, applicable forms, brokerage guidance, and qualified professional advice.

Common Property and Inspection Considerations in Indiana

Climate and Environment

NOAA’s Indiana State Climate Summary explains that Indiana’s location in the interior of North America exposes the state to cold Arctic air masses in winter and warm, humid Gulf air masses in summer. NOAA reports substantial geographic variation across the state, including lake-effect snow near Lake Michigan.[2]

NOAA reports a long-term statewide annual precipitation average of 40.5 inches for 1895–2020. Annual precipitation varies across Indiana, with the state summary reporting approximately 47 inches in the south and 37 inches in the north. Snowfall also varies substantially, from about 14 inches in the southwest to more than 70 inches in some northern locations near Lake Michigan.[2]

NOAA also documents periodic severe flooding, drought, winter snow and ice storms, thunderstorms, hail, and tornadoes in Indiana.[2] Use this section only as environmental context. Actual inspection findings and specialist evaluations control property-specific conclusions.

Radon

Radon is one of the environmental hazards that Indiana law requires the home-inspection report to state it does not address.[1] The Indiana Department of Health recommends that all Indiana residents test their homes for radon. In its updated February 2026 radon guide, IDOH states that nearly 1 in 3 Indiana homes are estimated to have radon levels that pose a significant health risk.[3]

IDOH states that the EPA action level is 4 pCi/L and recommends radon reduction for homes testing at or above that level.[3] Indiana requires individuals performing residential radon testing, analysis, and mitigation to be certified by the Indiana Department of Health under the Indiana Radon Rule.[4]

Private Septic Systems

Indiana’s required home-inspection report states that subterranean sewage-disposal systems are outside the report’s addressed scope.[1] The Indiana Department of Health reports that more than 800,000 onsite sewage-disposal systems are currently used in Indiana. IDOH reports that local health departments issue more than 15,000 permits per year for new onsite systems and about 6,000 permits for repairs.[5]

Do not assume that every septic system requires a particular inspection protocol; the appropriate scope depends on the property, jurisdiction, and qualified professional evaluation.

Private Wells

Indiana’s required home-inspection report states that subterranean water-supply systems are outside the report’s addressed scope.[1] The Indiana Department of Health states that private well water is unregulated by both the Indiana Department of Environmental Management and the Environmental Protection Agency, and well owners are responsible for their own safety when drinking from a private water source.[6]

IDOH recommends, at minimum, annual testing of private wells.[6] The IDOH Laboratory specifically recommends annual testing for bacteria and nitrate and testing at least every five years for fluoride, arsenic, lead, and copper, or whenever major maintenance is performed.[6]

Wood-Destroying Pests

Indiana law requires home-inspection reports to state that wood-destroying insects and organisms are not addressed by the home-inspection report.[1] Indiana separately recognizes Wood Destroying Pest Inspection as a credentialed activity associated with real estate transactions. The Indiana Department of Workforce Development’s credential summary identifies termites, wood-infesting beetles, carpenter ants, carpenter bees, and wood-decay fungus within this inspection category.[7]

Do not refer to a general home inspector as a pest inspector unless that individual separately holds the appropriate credential.

Lead-Based Paint

Lead-based paint is one of the environmental hazards Indiana law requires the home-inspection report to state it does not address.[1] The Indiana Department of Health states that lead-based paint is most often found in homes built before 1978 and that older housing has a higher likelihood of containing lead paint.[8]

IDOH also states that Indiana requires a license for individuals conducting specified lead-based-paint activities such as inspection, risk assessment, and abatement in target housing and child-occupied facilities.[8] The presence of pre-1978 housing does not establish that lead-based paint is present in a particular property.

Floodplain Information

The Indiana Department of Natural Resources operates the Indiana Floodplain Information Portal (INFIP). DNR states that the portal displays floodplain information from both FEMA and DNR sources, including mapped floodplains and flood-elevation points along waterways.[9]

Treat floodplain mapping as a separate official information resource. A home inspection is not a flood determination, and PropWise is not a flood-certification service.

Common Trade and Vendor Categories

Depending on the specific inspection finding or separate specialty testing, the post-inspection workflow may involve professionals such as:

• Plumbers
• Electricians
• HVAC contractors
• Roofing contractors
• Structural engineers or foundation specialists
• Radon testing or mitigation professionals
• Septic professionals
• Well or water-testing professionals
• Wood-destroying-pest inspectors
• Lead professionals
• Mold or environmental specialists

Licensing and credential requirements should be verified for the actual trade and jurisdiction. Indiana’s Business Owner’s Guide states that plumbers are the only construction contractors licensed statewide by the State of Indiana. Many other construction trades may be subject to local licensing requirements that vary by city or county.[10]
