El Cajon sets its own decibel limits in Municipal Code Section 17.115.130. On C-M and industrial land the one-hour average sound cap is 75 dB(A) any time (80 conditionally), measured at the property line. Where an industrial site borders homes, the stricter 50 dB(A) overnight residential limit applies.
El Cajon's performance standards, Municipal Code Section 17.115.130(C), cap the one-hour average sound level at the property line. Limits by zone: all residentially zoned land 60 dB(A) (7 a.m.-7 p.m.), 55 (7-10 p.m.), 50 (10 p.m.-7 a.m.); commercial and Mixed-Use land 65/60/55; C-M and industrial land 75 dB(A) any time, 80 conditionally. At a boundary between two zones the more restrictive zone's limit controls, so a data center in the M zone abutting homes must meet the 50 dB(A) overnight residential floor. Section 17.115.130(H) also requires HVAC units to sit 30 feet from the property line, behind walls, or in a mechanical room.
Sound over the Section 17.115.130 limits is a misdemeanor or infraction and a public nuisance, subject to citation, abatement, injunction, and any noise conditions the city attaches to a permit.
