Summary
Madera's Industrial Park (IP) zoning bans glare and heat from crossing a lot line. Madera Municipal Code § 10-3.11.506(E) sets an absolute standard, not a numeric threshold: any glare or heat that reaches beyond the property boundary of an IP-zoned use violates the zoning code, alongside the chapter's noise, odor, and vibration performance standards.
All uses in IP zones shall meet the following performance standards. ... (E) Glare and heat. Glare and heat from any source shall not be produced beyond the lot lines.

Full Breakdown
506 lists the performance standards that apply to every use permitted in Madera's IP (Industrial Park) zone. Subsection (A) caps noise with an octave-band decibel table, (B) limits particulate air emissions, (C) bars offensive odors beyond the lot lines, (D) bars perceptible vibration at the lot lines, and subsection (F) restricts radioactive materials and electrical interference. Subsection (E) covers glare and heat in a single sentence: glare and heat from any source in an IP zone shall not be produced beyond the lot lines. Unlike the noise standard, the code sets no decibel-style measurement or lumen threshold for glare; any detectable glare or heat crossing the property line is a violation on its face, which makes it a strict property-line rule rather than a graduated one.
The standard applies only to land zoned IP; it does not reach commercial, residential, or other industrial zoning classifications, which have their own separate use limitations elsewhere in Title X. 1602(A), including refusing or voiding any permit or license issued in conflict with it, and the Zoning Administrator and Planning Commission process the conditional use and use-permit applications that IP zone businesses need before they can operate. , passed May 31, 1972, and Madera has not amended subsection (E) since.
Violations & Fines
A use that lets glare or heat cross an IP zone's lot line violates Madera's zoning chapter and is a misdemeanor under Madera Municipal Code § 10-3.1603(A), the same penalty that applies to the chapter's noise, odor, and vibration standards. The Planning Director can also refuse or void a business license or building permit tied to the offending use under § 10-3.1602.
