Here me out.
I work from home. Yay.
I live in a residential area in US, near an elementary school across the street, with an apartment building in the way. I can hear kids out running around and playing in the yard. They get pretty noisy, but I'm fine with it.
Right next to the elementary school is an apartment complex where a guy seems to be running a motorcycle repair business based out of his apartment's garage. The garage faces the street, facing my home.
He tests the loud motorcycle engines about 1 - 2 times running a few minutes each time, about 3 - 5 times a week. One of these days, I'm going to super glue his garage shut so that he can't get the motorcycles in and out of the garage.
Ok, well, just kidding. I will just have to deal with it. But still, it is dang annoying to hear the motorcycle engines revving up as described above. I can't imagine how I can deal with a motorcycle/car repair shop across from my home.
Zoning laws are often used as a tool by people who practice NIMBYism, but the laws were introduced for a reason, and I support zoning laws because it would mean keeping certain types of businesses bit placed away from homes.
