Pulling a Permit mid project

[Tyler Young]

I am adding a bathroom and laundry room back to back and made the mistake of being influenced into not pulling a permit. I have only framed the walls, run pex and waste water piping(pier and beam) and now having cold feet. This same influence is saying that I would have to restart(cut out piping completely) if I pull a permit now. All my research leads me to believe I would only have to have it inspected not tore out unless its the work was performed incorrectly. Is there any harm to pulling a permit mid project other than having to admit that you started without the permit?
