You need to realize there are about 100 MILLION homes on Zillow, and only about 175 employees, and that the county records does not give longitude and latitude coordinates for the homes. There is no exact method of getting those coordinates presently. Some cities and counties are better than others. Much of the geocoding comes from the 9 digit zip code and the postal data for those. On straight streets that follow patterns, extrapolation is reasonably useful. On windy roads, extrapolation doesn't help much.
Sure, the U.S. Census office stated they will be geocoding all housing units in the U.S. as part of the 2010 U.S. Census; but that data is still not available.
In the meantime, Zillow has to rely on owners and agents to correct the locations. That is the only way it can work. The Zillow employees have no idea where any homes are but their own.

As the owner, you can correct much of the information on your home page yourself. Go to your main home page. Under the photo there is a yellow "Edit" pencil where you can claim your house and move your house icon on the map.
