There is a lot involved in a home inspection, but they don't cover everything you might expect. It is important to familiarize yourself with the standards of practice (SOP) and code of ethics that New York State, InterNACHI, and I impose on myself so that you can best understand exactly what your money is paying for:
How should my home inspector conduct himself/herself?;
Who does my home inspector work for?;
What (at a minimum) does my home inspector need to provide me with?;
Both sites are well worth reading and directly dictate how home inspections in New York State need to be conducted. If you still have questions, I am always available and more than happy to answer any question(s) at (315) 297-8177 or firstname.lastname@example.org.
