Moreno Valley homes

Only about 19 percent of Moreno Valley's roughly 57,000 homes go back before 1980 in Census Bureau survey estimates. The typical home was built around 1988, and about 28 percent are post-2000.

For most houses here, asbestos and lead are less likely, though not impossible. Leaks, mold and indoor air make up more of the questions in newer construction.

Chilly winter nights, hot July days

At NOAA's March AFB normals station, January lows average about 37°F and July highs about 94°F. Yearly rain is about 11 inches (1991-2020).

Chilly winter nights can produce condensation in attics and on cold-water lines. If you see staining, moisture mapping can show whether it's condensation or a leak.

Air district boundaries in Riverside County

CARB lists Riverside County as split: the western portion is in the South Coast AQMD and the eastern portion in the Mojave Desert AQMD. Check with your contractor which one applies before demolition.
