If you are planning to buy a new home then remember this. A city building inspector who inspected your new home, build a city official who oversees building inspectors and builder’s third-party inspectors, who supposedly perform quality control inspections for builders, have liability for you.
If they forgot any items or neglect or damaged any home item then they are responsible for its recovery. If you are searching online for a building inspector then you can have a peek here https://www.davidinspector.com.
In 30+ years of experience examining the house, I have heard the situations of builders or I have seen documents from the builder that the item or things that are called by the inspector buyer do not need to be discussed because "city" past items. What difference does that make you?
If it's wrong, it's wrong. "City" is not going to fix it. "City" cannot be sued for damages unless you can get the possible measures of the state legislature. And, in almost all cases, you cannot act like that of the legislature.
Furthermore, the code requires the building model structure code provisions instructions or factory installation requirements, which are more limited and must be maintained. I've never known a city building inspector imposed manufacturers’ installation requirements.
Another answer builders often give is that these items are installed or constructed in a way that the common practice in your area. General practice, always popular 'but everyone does it', does not mean approval or even safety, technique or size of the construction practices or procedures.
