Had you bothered to read my post fully you would have see that its not "local town law", its the OCGA, Official Code of Georgia, Annotated. Its the law of the land in Georgia, been upheld in courts. Sorry, but in some other states its the law also. Visiting the property for the purposes of inspecting it for taxation is not new, or unusual, again, if you read, it has nothing to do with going INSIDE any building, just the exterior of buildings and other improvements.

Well then the federal law and the 4th amendment stop at the Georgia state line. Good luck! I guess this is probably the only advantage to living in NY. The constitution is followed here. If the local tax guy shows up, cop or not and the property owner does not want them on the property they are both asked to leave if, this is not an emergency situation that is.

They appraised our shop at $25K for the tax year 2011 when it was built. I knew when they looked it over - I saw the footprints around the building. Busted! Anyway, when the assessment came in I simply filled out the protest form and mailed it back before the deadline. A few weeks later I got a call from the department for a follow up. He led off with "what can we do to help you?" and I just said I had right at $14K in receipts for the building and while I was proud of the ROI I thought the value was a bit high. No problem, value adjusted to 14K. Thanks, have a nice day.
