Decibel Limits: Camarillo vs Ventura

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.

What are the noise limits in the City of Ventura?

Residential zones: approximately 55 dBA daytime (7 AM-10 PM) and 45 dBA nighttime (10 PM-7 AM) at the property line. Commercial and industrial zones have higher limits. Both decibel measurements and a reasonable person standard apply.

What about noise from downtown restaurants and bars?

Commercial establishments must comply with both the general noise ordinance and specific conditions in their use permits. Entertainment venues in the Main Street corridor have noise conditions set during the permitting process.

How loud is 55 dBA?

55 dBA is roughly equivalent to a normal conversation at 3 feet or a quiet office. For reference, a typical gas lawn mower produces about 90 dBA and a vacuum cleaner about 70 dBA. Noise above 55 dBA at a neighbor's property line may constitute a violation in residential zones.
