Yeah, New Jersey is also highly regulated in home inspection. Plus their insurance requirements, most other states it's very little regulation, no insurance if anything.
Home inspection is a different creature, (I'd be shocked if most structural or civil engineers knew the home inspector is supposed to work every switch 5x and open and close every window 5x and turn water faucets on/off 5x.
Even a structural/civil engineer who did a "home inspection" isn't in that mindset and isn't typically aware of the NACHI checklists and or obligations. Most of them use specialized software and issue the reports "on site". They can still skip parts of their job (cough personal experience cough), and make big mistakes, but the contract usually says "liability limited to the cost of the inspection", again, probably not enforceable, but you have to fund the lawsuit to get the damages, survive various hearings and motion for summary judgement, etc. It's painfully obvious what they did wrong, so the fight that happens is to block the lawsuit to avoid a finding, or to limit the damages to teh $400 you paid.
Imagine a faulty furnace installed in an unoccupied house in the summer and "passed" by a home inspector (because they didn't look at it) and it leaks CO and kills a family of five. Then consider the $400 paid for a home inspection and the "limit" of damages (Not in New Jersey, mind you, you all have regs with teeth).
