Apple Valley, CA Noise Ordinances: Decibel Limits (2026)

The Town of Apple Valley sets numeric noise standards in Section 9.73.050, 'External and Internal Noise Standards.' Exterior limits in Table 9.73.050-A apply at the receiving property and vary by zone and time of day (daytime is 7 a.m.-10 p.m., nighttime is 10 p.m.-7 a.m.): single-family residential 50 dBA day / 40 dBA night; multiple-dwelling residential and public space 50 / 45 dBA; limited commercial & office 60 / 55 dBA; general commercial 65 / 60 dBA; light industrial 70 dBA at any time; heavy industrial 75 dBA at any time. Interior limits in Table 9.73.050-B for multi-family dwellings are 45 dBA daytime and 35 dBA nighttime. The chapter also includes correction rules: if the offending noise contains a steady audible tone (whine, screech, hum), is repetitive (hammering, riveting), or conveys music or speech, the applicable standard is reduced by 5 dBA, making it stricter. These figures are the Town's own standards under its Municipal Code and apply inside the incorporated Town; San Bernardino County's noise standards apply only to unincorporated land. California state law (e.g., Government Code and the General Plan noise-element framework) encourages local noise standards but generally does not set residential dBA caps directly, so Apple Valley's Table 9.73.050-A figures are the controlling limits within town limits.
