Summary
Apple Valley caps exterior noise at the receiving property: 50 dBA daytime and 40 dBA overnight at single-family homes, 70 dBA on light industrial land. Development Code Section 9.73.050 cuts every limit another 5 dBA for steady-tone equipment like chillers.
In the event the alleged offensive noise, as judged by the NCO, contains a steady, audible tone such as a whine, screech, or hum, or is a repetitive noise such as hammering or riveting, or contains music or speech conveying informational content, the standard limits set forth in Table 9.73.050-A shall be reduced by five (5) dBA. Table 9.73.050-A Exterior Noise Limits

Full Breakdown
Table 9.73.050-A sets exterior limits by receiving land use, measured on the other property: single-family residential 50 dBA (7 a.m.-10 p.m.) and 40 dBA (10 p.m.-7 a.m.); multiple dwelling and public space 50/45; limited commercial and office 60/55; general commercial 65/60; light industrial 70 and heavy industrial 75 at any time. Limits apply to noise lasting more than thirty minutes in an hour, rising 5, 10, 15, and 20 dBA for shorter durations. Section 9.73.050.A.2 reduces every limit by 5 dBA when the sound carries a steady audible tone such as a whine, screech, or hum - the case for data-center chillers and generators.
Violations & Fines
Noise over the Table 9.73.050-A limits is enforced by the Town's Noise Control Officer under Development Code Chapter 9.73, and breaches the noise conditions attached to any discretionary data-center permit.
