Bakersfield FAQ
A pump jack near my house runs 24/7 - is that legal?
Only if it stays below 45 dBA at your property line at night (with the tonal penalty applied). File a complaint with Code Enforcement to request a measurement.

What about construction noise?
Construction is separately allowed 6 a.m.-9 p.m. weekdays under BMC 9.22, exempt from the decibel limits if equipment is properly muffled.
Delano FAQ
