Housing in Caldwell and where water damage starts
Caldwell has about 22,378 homes, and half of them were built in 2003 or earlier. The city added roughly 12,918 residents between 2020 and 2024 (21.5%), so a large share of homes are recent builds. It is a mixed housing stock: 29% of homes predate 1980 while 56% were built in 2000 or later. Older neighborhoods tend to see aging plumbing and water heater failures, while newer construction more often brings appliance hose, ice-maker and fixture leaks into finished drywall and engineered flooring.
Caldwell climate and water risk
The nearest NOAA normals station, Nampa 4.8 Nnw, records 12.2 inches of precipitation in a normal year. That is a desert-dry total. Most water damage here starts inside the home, and when monsoon-type storms do arrive, dry ground and hard surfaces shed water quickly toward low spots, patios and doorways.
