Re: Here's another oldie
I managed the Code Enforcement program for ten years in Tulsa OK. We demolished about 110 buildings a year and left the lot slick to the dirt. Much of the time the property owners themselves didn't live in Tulsa or the property was dilapidated and had gone to a tax sale, etc. It wouldn't be unsual for there to be no none around to ask or deny permission. Contact your local city government and find out where urban renewal projects are being planned or ongoing. Just stay out of the way of the contractors until the demo work is done.
