Summary
Santa Maria caps light trespass from commercial and industrial glare sources at 0.5 footcandle measured in residential districts. Section 12-33.307 requires any operation producing glare to be shielded or conducted so illumination reaching a residential district never exceeds that threshold, and separately bars flickering or intrinsically bright light sources from becoming a nuisance there.
Section 12-33.307. Glare.
(a) No activity shall be permitted which causes light or glare to be transmitted or reflected in such concentrated quantities as to be detrimental or harmful to the use of surrounding properties or streets. Any operation or activity producing glare shall be conducted or shielded so as not to cause illumination in residential districts in excess of 0.5 footcandle. Flickering or intrinsically bright sources of illumination shall be controlled so as not to be a nuisance in residential districts.
(b) Illumination levels shall be measured with a photoelectron photometer having a spectral response similar to that of the human eye, following the standard spectral luminous efficiency curve adopted by the International Commission of Illumination.

Full Breakdown
301. 5 footcandle for illumination reaching a residential district from an industrial or commercial glare source. 5 footcandle mark once it crosses into a nearby home's zone. The section also separately restricts flickering lights and intrinsically bright sources of illumination, requiring they be controlled so they don't become a nuisance in residential districts, a standard that reaches strobing signage, bright security floodlights, or industrial process lighting even when the raw footcandle reading is close to compliant. Subsection (b) sets the enforcement method: illumination levels must be measured with a photoelectric photometer calibrated to the human eye's spectral response, following the standard luminous efficiency curve adopted by the International Commission of Illumination, so a Code Enforcement or Community Development inspector has a defined, repeatable way to test a complaint rather than relying on a visual judgment call. 5 footcandle standard is the operative light trespass limit for industrial and heavy commercial-manufacturing uses located near Santa Maria's residential neighborhoods.
Violations & Fines
An industrial or commercial use whose lighting exceeds 0.5 footcandle measured in an adjoining residential district, or whose flickering or bright light sources become a nuisance there, violates Section 12-33.307. The Zoning Administrator determines compliance under Section 12-33.301, and as with other Code violations, Section 1-6.01 makes the violation a misdemeanor punishable by a fine up to $1,000, up to six months in jail, or both, with each day of continued noncompliance a separate offense.
