Camarillo FAQ
What decibel level is too loud in Camarillo residential areas?
Any noise exceeding 55 dBA during the day (7 AM-9 PM) or 45 dBA at night (9 PM-7 AM) at the property line of a residential property violates CMC 10.34.040. For context, normal conversation is about 60 dBA and a lawn mower is typically 85-90 dBA.
Do interior noise limits apply to condos and townhomes?
Yes. CMC 10.34.050 sets interior noise limits for all common-wall dwellings and freestanding homes at 45 dBA daytime and 40 dBA nighttime. This is particularly relevant for Camarillo's many condo and townhome communities.
What is the ambient noise exceedance standard?
Under Standard B of Section 10.34.040, any noise source that raises the ambient level by 5 dBA or more at the receiving property line is a violation, even if the total level is below the zone limit. This prevents cumulative noise buildup.
Ojai FAQ
What are Ojai's decibel limits?
Residential zones have approximate limits of 50 dBA daytime and 40 dBA nighttime at the property line — stricter than most neighboring cities due to the valley's sound-carrying geography.
Why are Ojai's limits stricter?
The Ojai Valley acts as a natural amphitheater, carrying sound farther than flat terrain. The community values its peaceful environment, extending the dark sky philosophy to noise.
How are noise levels measured?
Code enforcement or Sheriff's deputies use calibrated sound level meters at the property line of the complaining party. Sustained noise levels are compared against the applicable zone limit.
