When we made the commitment to move to the Houston area, I thought “Texas, the land of personal freedom and smaller, less intrusive government” If you buy anywhere near Houston, you are about 99.9% guaranteed to be in an HOA neighborhood. We in Conroe 40 miles north of Houston, and we are 6 miles north of the Loop around the skirts of town, and we still have an HOA. It is an easy going one and the fees are small, but they still get finicky about some things, like they don’t want us to have a chicken coop with enclosed yard.
No greeneyes, there is not a limit to the number of 55 gal tanks, but they need to be hidden with shrubs. My neighbor has several 55 gal drums, but they are a dark green so the city hasn't said anything - yet.
