Step-by-Step: Conducting a Property Search Like a Pro

The GIS tool’s search function is powerful but needs skill to get the best results. Here’s a simple way to do it:

  • Search by Address: Type in a specific address (like “123 Main St, Warren, OH”) to get parcel details right away.

Mastering Data Layers for Deeper Insights

The GIS portal’s strength is in its data layers. These layers let you switch between views like zoning, aerial photos, or flood zones. In 2025, new zoning rules in Trumbull County will change property development. This makes the data layers very important.

  • How to Access: Click the “Layers” icon to pick options like parcel boundaries or infrastructure.
  • Key Layers to Use:
    • Zoning: See if a property is for homes or businesses.
    • Flood Zones: Stay away from high-risk areas with high insurance costs.
    • Land Use: Know what’s happening around you.

Pro Tip: Use zoning and flood layers together to find out if a property is a bad deal early on.
