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.

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.
