Searching For Properties

Access By PIN

You must enter a valid Area, Section, and Block to obtain a map. If you also enter a valid Parcel Number, the system will provide the address if there is a direct match.

Because Blocks can span multiple map sheets, it may be necessary to pan to the adjacent map to find the desired property. If the PIN has been recently assigned by the County, the map may not yet show the new parcel. New maps are added once a year.

Access By Address

You may enter an address to find the property. The address you enter will be standardized and geocoded to an approximate location. Find the desired parcel by inspecting the map page.

Map Navigation

Clicking on any spot on your map will redraw the map, centering on the point clicked. Use the panning frame surrounding the map to move your map in any of four different directions. Clicking on the top (North), bottom (South), right (East) or left (West) side of the frame will pan your map in that direction and display the adjacent map when an edge of a map is reached.

The zoom bar below the map is useful to help locate the desired property when a block spans multiple maps. Selecting zoom level 6 will display one entire tax map, and zoom level 3 is typically the most effective level to find street names. Level 1 or 2 are typically the best levels for viewing a single property.

Notes About Property Maps

The Property maps are a series of maps that show the general size and shape of each property. All of the blocks have been geo-located so it is possible to pan from one map to another.

The example below explains some helpful hints about the mapping conventions.
