Riverside County
Jurupa Valley Municipal Code §11.05.040 establishes a Table 1 of exterior sound-level standards (in dBA) measured at the property line of the receiving (impacted) property. The standards vary by the zoning of the receiving property and by time of day (a higher daytime number and a lower nighttime number). Section 11.05.060 layers "special sound source" rules on top. Always pull the live Table 1 from Municode before relying on a specific number — the table was set by Ordinance No. 2012-01 patterned after the Riverside County Noise Element and may have been amended.

Corona FAQ
How are noise levels measured in Corona?
Code Enforcement uses an A-weighted Type 1 or Type 2 sound level meter on slow response, taken at the receiving property line, typically averaged over a 1-hour Leq with separate analysis of peaks and impulse events.
Does Corona use decibel limits or the disturbance test?
Both. The ordinance allows enforcement based on either an objective dBA exceedance or a subjective finding that the noise disturbs a person of normal sensitivity.
Jurupa Valley FAQ
What is the residential nighttime dBA limit?
Section 11.05.040 Table 1 sets the residential nighttime number. The Riverside County source ordinance from which JVMC 11.05 derives commonly placed residential nighttime around 45 dBA and daytime around 55 dBA; pull the live Table 1 from Municode for the current City number before relying on it.
Can a complainant use a phone-app SPL meter?
Code Enforcement uses a calibrated Type 1 or Type 2 meter for citations. Phone-app readings are useful for documenting the pattern but generally are not enforceable evidence on their own.
Are sound levels measured at my property line or theirs?
At the property line of the impacted (receiving) parcel, per §11.05.040.
