How much housing does San Antonio have?
The Census counts 603,213 housing units in San Antonio for a population of about 1,458,954 — roughly 2.4 people for every housing unit.
That makes San Antonio the second largest of the five Texas cities with a page here; Houston counts 1,023,112.
Who arranges chimney work on a San Antonio home?
About 52.4% of occupied San Antonio homes are owner-occupied, which leaves about 47.6% rented.
Even at 52.4% owner-occupied, the remaining 47.6% of San Antonio 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 San Antonio chimney's earlier reports follow the property, not the occupant, so ask for them whichever side of that 52.4% you are on.
Which cities near San Antonio have their own page here?
Austin, about 74 miles away, Houston, about 190 miles away, Dallas, about 253 miles away, and El Paso, about 498 miles away — measured from San Antonio.
Those are great-circle distances between the Census 2023 Gazetteer interior points of each place, so the drive is longer than the figure.
Austin's median build year is 1993 against San Antonio's 1984, a 9-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.
