Fuck this. This exact thing happened to me. I live in the PNW, Washington State, USA, to be exact. I spent a year or more building my place to spec. Lived in it from 2020 to 2023, when I was informed that I was in violation of local laws.
When asked how I was discovered, they said a neighbor reported me.
Fuck this idiotic world. I was living a good life. I've been in the middle of the city since and can't say I'm better for it.
