Just about every day I am researching properties for my clients (either buyer or seller), and there are a LOT of online resources available.  Here is a short list of some of the web sites you might be interested in for researching your own property, or a property that you are considering purchasing.

City of Harrisonburg

• Real Estate Information System - owner, property and assessment information
• Geographic Information System (GIS) - interactive map
• City Maps - top maps, tax maps, etc.
  
• Zoning Code
• Comprehensive Plan
  
• Harrisonburg City Schools
  

Rockingham County

• Geographic Information System (GIS)
• Zoning Code
  
• Comprehensive Plan
• Rockingham County Schools
  

In addition, there are several other sources of information that I have access to via my profession:

• Tax Records (city and county, via our MLS)
• Recorded documents (via subscription)
  

If I can be of assistance to you in researching a property, please let me know.
