Corona homes
The median Corona home was built in 1991, per the American Community Survey. About 25 percent of its roughly 51,000 homes date from 2000 on, and about 25 percent from before 1980.
Older homes near downtown can have asbestos in ceilings and floors and lead in paint from before 1978. In the newer subdivisions, people more often call about plumbing leaks and indoor air.
Inland heat
At Riverside's municipal airport, a nearby NOAA normals station, August afternoons average about 95°F. Rain totals roughly 9 inches a year and peaks in February (1991-2020).
Long cooling seasons mean air conditioning runs for months, and a clogged condensate drain can soak a ceiling quietly. A partner can trace the moisture or sample suspected mold.
South Coast AQMD
Corona is in the South Coast AQMD, which CARB lists for western Riverside County. Ask your contractor whether a demolition or major remodel needs an asbestos survey and a district filing first.

Can I request mold testing for a Corona townhome?
Yes. Say whether the problem is inside your unit or in a wall you share with a neighbor; HOA approval may be needed for shared areas.
Do you cover businesses in Corona?
Yes. Commercial sites can request testing such as silica dust or OSHA PEL exposure testing; describe the work and the site.
