I'll bet you have no clue how many home businesses are 'illegally' operating in your neighborhood.

There are a lot of rural cities that “annex” farm property out several miles. That puts those farms and small business operating under county rule, directly under the city zoning board authority.
Creeping socialism. Creeping authoritarianism. He may very well have been annexed, then denied commercial zoning afterward. I suspect that’s what happened.
And as long as they're not generating undue noise, traffic, pollution, or otherwise harming me or my property values, neither I nor the zoning board care.
