I heard some counties that use Mobile Assessor was trying to push some details to Qpublic who then make some announcements or indication of visitation schedules on the web.

From a technology perspective, if we had email addresses or cell phone numbers we could build a tool that delivers electronic notifcation via text messages or emails. Another thing, your office could create a social media account, invite your citizens to follow that account and you could make a simple twiter/instagram/facebook post on the daily to alert citizens where the visits will be occurring. There are lots of options.
