asbestos and burned houses

[John Reid]

While driving around this morning scouting a neighborhood one of my partners and I came across a corner lot on a middle class street across from an elementary school. The house had burned and the owner was asking $2000. I went to our county assessors website to get the history of the structure. It was built in 1922 and had 1808 sq ft of livable space. Per the website there are no back taxes due. I am interested in buying the property and having the house torn down but have never done this before. My concern is with asbestos in an old house. My questions include:
1. In the case of a fire do the same rules and regs apply for tearing down an old structure? I had an old existing garage torn down on my personal property and had to have an asbestos inspection before a permit could be issued to the excavator.
2. If the house is an eyesore for the neighborhood and the city could a waiver be issued by the city for asbestos removal?
3. After a fire is the asbestos considered to have been "disturbed" (even though it's technically supposed to be fireproof) thus negating all the rules and regs for removal to begin with?
4. Will inspectors even enter a dangerous, burned out structure to take samples for lab testing? This could be reason enough for the city to grant a waiver.

Any insight and personal experience with asbestos in burned houses would be most appreciated. Thanks!
