Each project requires a different set of inspections, especially if the project is located in a regulated watershed.

During the preconstruction meeting the inspector will discuss your required inspections, along with important information about permit conditions that will be required as your project moves toward final occupancy. Learn more about inspection requirements with this printable document. inspection requirements

16. Do I have to be present when the inspector arrives?

No, except for the preconstruction meeting. If you are unavailable to be on site for any other inspections you must make provisions to allow for inspector entry (i.e., instructions on where the key is located, etc.). If there are corrections necessary prior to signing off on a particular inspection, a correction notice will be left on site. When an inspection is approved, the appropriate portion of your inspection record will be signed and dated. Note: The inspection record is your permanent record, so don't lose it!

18. When can I "occupy" or use my house / structure?

Occupancy and use of the structure begins only after the final inspection has been signed off. You are in violation of code if you occupy the premises prior to that, unless the inspector has granted you temporary occupancy (i.e. approval to habitat the structure subject to a list of outstanding requirements that must be completed prior to final occupancy).
