How could a home inspector inspect the wrong house? It's not as tough as it sounds. I've done it twice myself, and at least one other person on my team did it recently. Possibly several inspectors on my team, but only one that I know about ;-).
Wrong Home Inspection
My second 'wrong home' inspection happened in 2008. I knew that I was supposed to inspect a home listed by Re/Max, so I drove down the street looking for the Re/Max sign. Boom. There it was. The home had a manual lockbox code of H-O-T or something like that, and it worked, so I proceeded to inspect the home as usual.
You can guess what happened, right?
The house that I was supposed to be inspecting was about four houses away. Same agency, same lockbox code. Luckily, my clients called to ask where I was about an hour into the inspection. That's the last time I ever made that mistake.
Lesson learned: Double-check the darned house number. Just because the lockbox code works doesn't mean you're at the right house.
Wrong Truth-In-Housing Evaluation
The first time I inspected the wrong house was for a Truth-In-Sale of Housing (TISH) evaluation, which is a pre-sale listing inspection that's required in Minneapolis. It's also known as a "City Inspection" because we do these on behalf of the city of Minneapolis.
The year was 2005, and we received a lot of referrals from an agent who would order inspections on behalf of her Spanish-speaking clients. She ordered a city inspection for a property located on Columbus Avenue, but I went to the same house number on Chicago Avenue, which is one block away.
I knocked on the door and was greeted by Spanish-speaking occupants. They seemed confused and unsure of why I was there, but that was par for the course and I didn't let it stop me. I cheerfully introducing myself as the Truth-In-Sale of Housing Evaluator, showed them my city ID card, and proceeded to inspect the home as usual, repeating "ees ok" as needed.
