What Casa Grande's numbers say about water damage
Casa Grande is one of the fastest-growing Phoenix-metro suburbs tracked here: 69,753 people (2025 estimate), up 29.9% since 2020[3]. On the map that's 114.2 square miles holding 611 residents per square mile, the 14th densest of the suburbs here; it sits entirely in Pinal County, with ZIP codes 85122, 85193, 85194[4].
Casa Grande mixes 19% of homes built since 2010 and 21% before 1980[2]: new supply lines and water heaters in one house, aging pipe and original valves in the next — so where a leak starts depends a lot on the address.
