What must all inspections include?

A written report is essential for all inspections because it serves as a formal document that communicates the findings of the inspection to all relevant parties, including property owners, buyers, and real estate agents. This report typically outlines the condition of various systems and components within the property, documenting any issues or concerns that were observed during the inspection process.

Having a written report provides a clear and organized way to convey important information and ensures that details are not forgotten or miscommunicated over time. The report also serves as a legal record, protecting all parties involved in the transaction and providing a reference for any future assessments or repairs that may be needed.

While the other options involve technical assessments or specialized analysis, they are not universally required in home inspections, which primarily focus on the overall condition of a property rather than detailed engineering or system efficiency calculations. The key focus of a home inspection is to provide a general assessment of the property's condition, which is most effectively communicated through a thorough written report.
