Decibel Limits: Ojai vs Ventura

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.

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.
