Houses marked as "contributing" have been identified as part of Eastmoreland's historic inventory. In a historic district they will have additional protections against alteration, remodeling and demolition. The flip side of protections is that they can also restrict your ability to change your home's functionality or appearance. Find your home here and see if it's considered historic in character ("contributing") and facing restrictions, or "non-contributing" (not part of the historic inventory, and free from most HD restrictions.)
