The limit specified in San Diego County Code Section 36.404, General Sound Level Limits, at the property line of the property on which the noise is produced or at any location on a property that is receiving the noise.
Full Breakdown
San Diego County Code Sec. 36.404 sets one-hour average sound level limits measured at the property line of the source or on the receiving property. Subsection (1) covers the R-S, R-D, R-R, R-MH, A-70, and A-72 zones: 50 dBA between 7 a.m. and 10 p.m., and 45 dBA between 10 p.m. and 7 a.m. Commercial zones get 60 dBA day and 55 dBA night. M50, M52, and M54 industrial zones allow 70 dBA at any hour; S-82, M56, and M58 allow 75 dBA. At a boundary between two zones the limit is the arithmetic mean of both. Bostonia has no city noise ordinance to add to these.
Violations & Fines
Noise over the Sec. 36.404 limits is enforced by San Diego County, and a permitted data center also breaches the noise conditions attached to its Major Use Permit.
