Housing across the county
The American Community Survey counts roughly 126,000 housing units in San Luis Obispo County. Around 44 percent of them went up before 1980 and about 24 percent since 2000, for a median year of 1983.
A ranch house or beach cottage from before 1980 may still have its original ceiling texture, floor tile or pipe lagging, all materials EPA lists as possible asbestos sources. Lead paint becomes a question for anything painted before 1978.
Wet winters in San Luis Obispo
At the San Luis Obispo Poly station, NOAA's 1991-2020 normals total roughly 22 inches a year, of which about 19 arrive from November through March. January tops the list.
Summers at that station are close to dry, with 0.32 inches of rain on average from June through September, so a wall soaked in a winter storm has months to stay damp unnoticed. If storm water reached a crawl space, mold testing can show whether it dried out.
Private wells in rural areas
Ranch and vineyard properties may run on their own well. Well water testing through a partner can cover the items you name, and the partner explains which tests fit.
Air district paperwork
San Luis Obispo County has its own air district, the San Luis Obispo County APCD, according to CARB. Federal NESHAP rules can require an asbestos survey before many demolition projects and some remodels in the county, with notice filed with that district.

Questions
Can I get my well tested near Paso Robles?
Yes. Request water quality testing, mention the well, and list any concerns, such as taste or staining. We look for a partner who serves that part of the county.
Is a house in Atascadero old enough to need a lead test?
If it was built or painted before 1978, a lead test is worth doing before sanding, scraping or replacing old windows.
