Unknown Fairfield Landlord Requirement

Landlords in Fairfield MUST obtain Certificate of Rental Occupancy from Department of Health. This is different than, and in addition to, compliance other municipal requirements (building, zoning). The folks in DPH in my experience have been helpful, responsive/timely, and pleasant to deal with. I post about this topic because I had another issue with it pop up yesterday. No one knows of the requirement, so I'm just trying to help get word out.
