If I had a dollar for every time I've heard this comment, I would be living in the Bahamas right now!
First, let me set the scene; I'm a retired General Contractor with sub-licenses in HVAC, Plumbing and Electrical. I've paid my dues arguing with City Inspectors for many years. I'm not saying all City inspectors are lazy, crooked, or lax in their duties. There are some that are, just like in any other profession. Most are hard working professionals doing the best they can under the circumstances.
The biggest issue is lack of funding, under staffing and heavy workload. Most are expected to do 15-25 inspections a day! And on residential, they are "All-Trade" inspectors, making the call on 12 or more trades. No one can know everything about everything. They pick their battles and let the rest slide, many times they are given the "fault de jour" to look for by the higher ups. (I think they pick them with a dart board)
Realtors! Listen up! The City Inspector is far too busy to catch everything. As a Home Inspector (for the last 6 years with over 2500 inspections), I spend 2-4 hours going over a house I'm inspecting. The City Inspector spends 15-20 minutes if you are lucky because he/she has 20 more to do today. The shifty contractors are very good at dissembling and miss-directing to avoid getting caught out. There are lots of little "tricks-of-the-trade" that can be used. Little things like making an obvious glaring mistake that the inspector will be sure to find and then using up all his time on site "discussing" a fix for it that he will pass. Now he/she just signs off the rest, often with out further investigation because he's waaaaay behind.
He never catches all the "cheats" that are usually there but gets waylaid by the phony defect placed there for his benefit. Believe me, THERE ARE LOTS OF THEM! We find them all the time because we have the time to look.
Another issue is that the City operates under the shield of "In the Public good" and this basically means THEY ARE NOT RESPONSIBLE for misses. If they were held responsible for mistakes, the City would be sued every other day and they could never do the job. Construction would grind to a halt! Talk about a pissed off public! The houses would get build one at a time and take 6-9 months each. Every City inspection would take all day for each phase and there would need to be specialists for each trade.
So, the next time the Home Inspector says something is wrong, please don't say "the city inspector said.........". You might just get a knuckle sandwich! LOL Just kidding! I usually just say 'that's nice, but it's still wrong and not safe". "You DO care about the safety of your clients, right?" Not to mention the safety of your bank account and E & O insurance deductible.
The City Inspector Said It Was Okay is like getting a D grade on an exam.
Do you want to live with a D grade, when you are expecting an A grade.
