A home builder or remodeler will have varying attitudes, ranging from full compliance with best practices / law via hiring a certified abatement subcontractor vs "just leave us the keys and someone will get it out overnight." You should call a good local environmental engineer, who will give you direction you need. Will cost a few grand. Alternatively, if its a bathroom's worth of 'hot' ceramic tile (having asbestos or lead), best, legal bet is to just call an abatement company and have them rip it out on the assumption that its hot. You will spend more on testing and research than just following protocol and sending it off to the appropriate landfill. Or if you are tightly budget constrained, just leave the tile in place and place new tile on top. Thats the easiest of all. Hope thats helpful. (edited with a few clarifications)
