Summary
When a Stockton industrial use abuts homes, its noise cannot exceed 55 dB Leq by day or 45 dB Leq at night at the receiving property line, under Development Code Table 3-7, Part II. A data center's chillers, fans, and generators must meet these limits.
If commercial, industrial, or public facilities land uses are adjacent to any noise-sensitive land uses or vacant residential (RE, RL, RM, or RH) or open space (OS) zoning districts, these uses shall comply with the performance standards contained in Table 3-7, Part II.

Full Breakdown
Stockton has no noise rule written for data centers, so a facility's chillers and backup generators are held to the Development Code noise standards in Chapter 16.60. Where industrial uses abut noise-sensitive uses or residential (RE, RL, RM, RH) or open space (OS) districts, they must meet Table 3-7, Part II: the hourly equivalent level (Leq) may not exceed 55 dB from 7 a.m. to 10 p.m. or 45 dB overnight, and the maximum level (Lmax) may not exceed 75 dB day or 65 dB night, at the receiving property line. Each standard drops 5 dB for tonal noise. Backup generators must be enclosed and cannot exceed 76 dBA Lmax at 23 feet.
Violations & Fines
Cooling or generator noise exceeding 55 dB Leq by day or 45 dB by night at a neighboring home violates Chapter 16.60; the City can require an acoustical study and mitigation, and unmitigated noise can block a use permit.
