Riverside County Ord. 847 sets A-weighted dBA limits that vary by receiving land use, with residential nighttime limits around 45 dBA and daytime limits near 55 dBA.
Ordinance No. 847 establishes a table of maximum allowable exterior noise levels measured at the receiving property line, based on the zoning of the receiving parcel rather than the source. Typical published values: rural residential (R-R, R-A) 50 dBA day / 40 dBA night; standard residential 55 dBA day / 45 dBA night; commercial 65 dBA day / 55 dBA night; industrial 75 dBA day and night. Short-duration exceedances are allowed (e.g., no more than 30 minutes per hour at +5 dBA, 15 minutes at +10 dBA, 5 minutes at +15 dBA, and no more than 1 minute at +20 dBA). Measurements use slow-response A-weighting at least three feet from any wall. Impulse noise (such as gunfire on shooting ranges or rock crushing) is subject to additional limits. Officers typically use calibrated Type 2 sound level meters; the plainly-audible standard can substitute when meter readings are impractical.
Citations begin around $100 with escalation; continuing violations can be abated as public nuisances.
