Mostly newer, with older pockets
The ACS 2020-2024 estimates count roughly 60,000 homes in Fontana, about 32 percent of them built since 2000; the median year is 1989. Around 28 percent are from before 1980.
Homes in that older share can have asbestos in ceilings or flooring and lead in pre-1978 paint. Newer homes more often raise questions about leaks, mold and air quality.
Inland heat
At Ontario International Airport, NOAA's normals station for the area, August highs average about 95°F and annual rain is about 12 inches (1991-2020).
When outdoor air is this dry, mold indoors almost always traces to a plumbing, appliance or roof leak. Finding the source matters as much as the test itself.
Dust from cutting and grinding
Cutting concrete, tile or stone can put silica dust in the air. Contractors and homeowners can request silica dust testing or OSHA PEL exposure testing during that kind of work.

Questions
Do you handle requests for Fontana businesses?
Yes. Commercial sites can request tests such as silica dust or exposure testing. Tell us the type of site and the work being done.
Is a 1980s Fontana house likely to have lead paint?
Residential lead paint was banned in 1978, which makes it less likely in a 1980s house. A test settles it if you're unsure.
