We are fortunate to have a local online site, Swamplot.com, that is real estate oriented and they daily publish on line the demo permits issued by the City of Houston the previous day. They give the address and zip code. We then search using the street address and zip and get real estate infromation on the site giving us the 'build' date for eh exixting home. We thn visit the site. If there are demo crews there we ask for permission to detect the place. If they are not there and the house is down we hunt it. We have never been asked to leave any demo site othere than large ones where the company has 'liability' issues. We usually hit between 8 to 15 demolition sites a week. Usually spend about 3 to 4 hours on each and move on. Like most of us, we fill the holes, and if we dig it we take it off the lot. We have had lot owners, builders, real estate agents and neighbors come over and check us out. We always stop what we are doing, greeet them, shake hands give them our names, and let them know how much we enjoy doing what we are doing, metal detecting.
And, if things get slow we drive around certain zip codes and look for sites to hunt. Best ones are old school sites, old store or bar sites with patio decks of boards, and of course the street and sidewalk demolitions or renovations. I got my best ring from under an old sidewalk laid in the late 1950's. Appraised at about $6000. We hit one old beer joint, Ice House, where they had decks of wood planks around several of the trees, covering about 500 sq ft. In less than 2 hours I picked up or dug over 200 coins. 88 clad quarters alone, plus a $5 dollar bill. Between my hunting buddy and I, we had over $120 in clad.
