Error: You should only filter if the parameter is true? I'm not sure how this is wrong.

index.php 
<?php
function get_people($treehouse = null) {
  include 'connection.php';
  $sql = 'SELECT * FROM people ';
  $where  = (!empty($treehouse)? ' WHERE treehouse = 1  ' : '');
  $orderBy = ' ORDER BY last_name DESC';

  $results = $db->query($sql . $where . $orderBy);
  return $results->fetchAll(PDO::FETCH_ASSOC);
}
