Retrieve entries on custom field date using ElementCriteriaModel
The Error was because 


  $criteria->inspectionDate > '("now")';


This way you can't get today's date.

You could try this:

$date = new DateTime();
$formattedDate = $date-&gt;format(DateTime::MYSQL_DATETIME);
$criteria = craft()-&gt;elements-&gt;getCriteria(ElementType::Entry);
$criteria-&gt;section = 'inspections';
$criteria-&gt;inspectionDate = '&gt; '.$formattedDate;
$criteria-&gt;order = 'dateCreated asc';
$inspections = $criteria-&gt;find();
