Hypothetically, let's say you decide to do some indoor renovations but not get a permit and you know the work requires permit (e.g. electrical, framing, etc). Also, you lower the blinds on all windows, keep the outside of the house intact, and do not accumulate trash, IOW, you are as clandestine as you can be.
Let's say the building police (what I like to call them) drive around or someone tips them (maybe neighbors over noise) that there is suspicious construction going on but, from the outside they can't prove you are doing anything cause you have sealed the inside visually.
In the U.S., is there any way for the building inspectors to obtain a search warrant to forcibly check what is going on inside?
Disclaimer: This is not me. I am just wondering about a hypothetical scenario.
