Riverside, CA Filming & Production: Production Noise (2026)

Riverside Municipal Code Chapter 7.35 sets exterior sound limits by zone and time: residential zones are limited to 55 dBA daytime (7 a.m. to 10 p.m.) and 45 dBA nighttime, measured at the property line of the receiving property. Film productions are considered short-term commercial activities and may apply for a noise variance through the Film Office in coordination with Community and Economic Development. Variance conditions typically include: written notice to residents within 300 feet at least 72 hours in advance, a community-impact letter with the name and 24-hour phone of a production contact, defined shoot hours, limits on exterior amplified dialogue playback or music between 10 p.m. and 7 a.m., and use of baffled generators when within 100 feet of residences. Pyrotechnics and blank-fire gunfire require a separate Fire Department permit under Health and Safety Code Section 12500 and California Code of Regulations Title 19, and cannot occur after 10 p.m. in residential zones without mayoral or council approval. Failure to comply can result in stop-work orders, permit revocation, and denial of future permits. Productions should also confirm that generator emissions meet CARB Tier 4 or equivalent where required.
