The courts are ruling it unconstitutional all over the place, as they should be.
This will be fought and struck down. I'm REALLY interested to talk to my attorney about it next week, I'd bet there is pending litigation. I'd love to join it.
Fucking hell. I've never needed a lawyer in my entire life, now I've got him on speed dial.
I did some more digging on it - it's a very very fine line, it seems.
A Federal court did rule against an Ohio town for a similar program - but, it's not specifically a ruling that invalidates all rental inspections.
There seems to be some leeway, because, let's face it, while at first blush it may appear to be a violation of the Fourth Amendment, do note that said Amendment states "unreasonable" as a major qualification.
There are other towns in Ohio that have less strict wording, and the very same town (Portsmouth) that was found to be in violation of the Fourth re-wrote their policy; here, it seems that if both the tenant and landlord deny permission to enter, then the inspectors are either out cold or they have to get a court order/warrant. If tenant denies, they'll try to work with the landlord to get approval (and that would legally usurp the tenant AFAIK)... if that fails, then they are left with the courts.
It seems these ARE at least being taken up by State and Federal courts, so we may win out after all. But it is going to be a very tough effort to get Judges to agree that these are, by definition, unreasonable. I didn't read the letters in your OP... did they give you an option to deny the inspectors access?
It is a very sticky subject, as usually what is seen cannot be considered evidence or reported, but then again, if they see evidence of a meth lab, they usually are within their rights to report that. That alone is a sticky subject in of itself, because in many ways, that makes plenty of sense: a meth lab --unlike growing pot, for instance-- is a serious threat to the property, which is entirely the point of the rental inspections (not drugs or crime, just structural integrity and healthy living conditions). And not only is it an issue with the property, if you have multiple tenants, all of them are at risk for health concerns, AND the properties are usually ordered to be vacated and are demolished due to the chemicals used. But it probably shouldn't be used as a means to prosecute anybody, but I don't think that is the case: I suspect if an inspection turns up a meth lab, that report then sets into motion a search warrant and investigation. But it was only initially reported due to being a hazard to both health and property. Any other evidence should be easily thrown out in court if it came to be.
