How much housing does Rock Hill have?
The Census counts 33,556 housing units in Rock Hill for a population of about 74,769 — roughly 2.2 people for every housing unit.

Who arranges chimney work on a Rock Hill home?
About 53.5% of occupied Rock Hill homes are owner-occupied, which leaves about 46.5% rented.
Even at 53.5% owner-occupied, the remaining 46.5% of Rock Hill homes are rented, where the person who notices a problem and the person who authorizes the repair are not the same. Say which you are when you send a request.
Tenure also decides who keeps the paperwork. A Rock Hill chimney's earlier reports follow the property, not the occupant, so ask for them whichever side of that 53.5% you are on.
Which cities near Rock Hill have their own page here?
Columbia, about 62 miles away, Greenville, about 76 miles away, and Charleston, about 158 miles away — measured from Rock Hill.
Those are great-circle distances between the Census 2023 Gazetteer interior points of each place, so the drive is longer than the figure.
Columbia's median build year is 1978 against Rock Hill's 1995, a 17-year difference in the housing the two chimneys belong to.

Can this be diagnosed from a photo?
A photo can document a symptom and help prepare a visit. It cannot confirm concealed conditions or establish that a chimney or fuel-burning appliance is safe.
