Research a Property
What you can Build or Do on a Property
Find out everything you can about a property, and which County codes and inspections* may apply. For example, does the property have gopher soils, certified water sources, road access? What zone is it in? Are there outstanding tax or regulatory issues? 

1. Look up a property online.
