[MassHistPres] criteria for demolition delay

[Kjgkeith at aol.com]

The Canton Historical Commission is re-examining its criteria for  demolition 
delay and would appreciate learning what other historical  commissions use as 
criteria, other than documented historical  significance, and/or visible 
architectural features.  If a property  owner who is seeking a demo permit does 
not know a building's construction  date, has any commission issued a temporary 
delay to a demolition permit in  order to research the original deed?  We 
understand that we cannot require  the owner to do this research, and it would be 
incumbent upon the  commission to conduct the research.  
 
Thanks for any information.
