What?! You can't park a unicycle in your yard?
As I said before, I thought city codes usually dealt with unsightly houses in a neighborhood with two options - either clean it up or fence it in so no one can see your junked up yard. That seems to be the alternatives in AR. Although I will say it's less than enforced in the extreme rural areas.
In one place not far from the farm where I work on one side of the road there is this really nice one story brick house with a carport. The yard is kept mowed, the house is well maintained, and it looks really good. Then on the other side of the road there is is this place where there's a small older one story house that looks like it was built as an original one-room farm home that has been added on to numerous times. And not too far from that is an old single wide trailer home. Both dwellings belong to the same family and both are being used. But here's what it looks like. There is an old broke down school bus that's sitting on the wheels (no tires), it's filled with junk and on the back end near the exit they have a window A/C unit in it. There are several dogs tied up to trees all over the property. Trash and garbage is strewn everywhere and they have several vehicles that are older and are not well maintained. Also, their yard is little more than mud and piles of trash, no grass to speak of unless you want to count the weeds along the ditch in their front yard.
The reason they aren't told to clean it up is because it's on a county dirt road way back in the boonies and they aren't in any city limits although technically they could fall under the Belleville township I think. If nothing else the ADEQ and possibly APS/CPS should look into it given it's hazardous not to just the people, but also the surrounding environment. The property backs right up to state lands.
