It's my understanding that the property was renovated/reconfigured a few years ago for exactly that purpose.

Totally possible... though from my (admittedly minimal) understanding, that sort of facility/renovation comes with somewhat different codes and rules. Again, just putting it out there as something potentially worth verifying.

There would have had to been a hearing to do something like that. I don't recall that happening.

Just relaying the comments from a former tenant around the time of construction. I doubt code/rules were consulted for those renovations.

LCI are you listening?

The Vision Appraisal database still lists the house as 4 bedrooms total. I'm pretty sure that's no longer the case.

This issue should be resolved. The property has a rental license
