For myself, I hired a CPA who was a former IRS auditor, best $ ever spent, and ROI.  

Section (A)(1) provides:(1) When water rents or charges are not paid when due, the director or other official or body may do either or both of the following:(a) Certify them, together with any penalties, to the county auditor.

Take a look at their SEC filings, specifically the bit that says something like "our auditors have expressed serious reservations about our ability to continue operating as an ongoing concern" and how the founders are all taking pay cuts to stay operating. 

My next step is to pull up the info on the county auditor website and then try to touch base with the owners of said properties.

This might lead to a sticky situation upon audit or examination, particularly if the three year statute has lapsed but the six year has not.

If it's a single person LLC it's really easy to do yourself on your state auditor site.

I have heard of it being done by going to your county auditors office and looking the property up.

If you're ever audited by the IRS or need "audited" financials to raise money or sell equity/debt auditors will all know Quickbooks making the process far easier.  4.  

Normally, the City is the one that approves tax abatements, then passes them on to the county assessor/auditor office to determine the value of the abatement.  

As far as I know, all permits should appear on the auditor's page for a certain property.
