Lodi FAQ
Does Lodi have a single decibel cap like 'no more than 55 dB at the property line'?
Lodi's enforceable standard is the General Plan Noise Element CNEL matrix combined with Chapter 9.24's nuisance test (plainly audible across the property line, especially after 10 p.m.), rather than a single fixed dB cap.
Why is nighttime noise treated more harshly?
CNEL applies a 10 dB penalty to sound events between 10 p.m. and 7 a.m. So a 60 dB nighttime source counts the same as a 70 dB daytime source for compatibility purposes.
Stockton FAQ
Where in the Municipal Code are Stockton's decibel limits set?
Stockton Municipal Code Title 16 (Development Code), Chapter 16.60 (Noise Standards), sets exterior noise limits in dBA by receiving zone with separate daytime and nighttime values.
Are limits measured at the noisy property or the complainant's property?
At the receiving property line — the residence or other parcel being affected. The receiving zone's standard applies, not the source zone's standard.
What if a noise stays below the numeric limit but is still disruptive?
SMC Chapter 8.20 (Noise Regulations) supplies a qualitative public-nuisance standard, and California Penal Code § 415 makes willful loud and unreasonable noise a separate offense punishable by up to $400 and 90 days county jail.
