Pasadena's Outdoor Lighting: The Rules That Matter

Every city handles outdoor lighting a little differently. In Pasadena, California, there are 3 distinct rules that residents and property owners should be aware of. Some are stricter than what neighboring cities enforce, and others are more relaxed. Here is what you need to know.

Billboard Lighting

Pasadena bans electrical billboard, sign, and decorative lighting outright under Section 13.08.010, then carves out a narrow exception: Section 13.08.020 lets a billboard be lit only between sunset and 10:30 p.m. Break the curfew and Pasadena Water and Power can cut your electric service until you comply.

Key details: Default rule: All billboard lighting banned (§13.08.010). Illumination window: Sunset to 10:30 p.m. (§13.08.020). Reduced-period window: Same sunset-10:30 p.m. hours retained (§13.08.030). Service disconnection: PWP can cut power until compliance. Criminal penalty: Misdemeanor, up to $500 fine or 6 months jail.

Noncompliance carries two separate consequences. Section 13.08.120 lets the general manager of Pasadena Water and Power disconnect a violator's electric service until compliance is achieved, after written notice. Independently, Section 13.08.130 makes any violation of Chapter 13.08 a misdemeanor punishable by a fine of up to $500, up to 6 months in jail, or both, with each separate day of violation counted as its own offense.

Dark Sky Rules

Pasadena requires all exterior lighting on private property to be shielded, energy-efficient and directed downward and away from adjoining properties, per Municipal Code Section 17.40.080. Fixtures cannot blink, flash or run unusually bright, and sports court or field lighting within 300 feet of a residential zone needs a Minor Conditional Use Permit.

Key details: Governing section: Municipal Code § 17.40.080. Shielding standard: Directed downward, away from neighbors. Flashing/strobe lighting: Prohibited outright. Sports/field lighting near homes: Minor CUP required within 300 ft. Enforcing agency: Zoning Administrator.

The Zoning Administrator enforces Section 17.40.080 during Building Permit and Code Compliance Certificate review; noncompliant fixtures can be ordered shielded, redirected or removed before occupancy sign-off. Installing sports or field lighting within 300 feet of a residential zone without first obtaining a Minor Conditional Use Permit is a zoning violation subject to the City's standard code enforcement process, including correction orders.

Light Trespass & Shielding

Pasadena caps how much artificial light can spill onto neighboring residential land: Municipal Code Section 17.40.080.A bars any private lighting from producing more than one footcandle of illumination on adjacent residential-zoned property, measured off the light source's own site.

Key details: Footcandle cap: 1.0 footcandle max on neighboring residential land. Measured: On the receiving property, not the source. Governing section: Municipal Code § 17.40.080.A. Applies to: All private lighting citywide. Paired requirement: Fixtures must be shielded, aimed downward.

A lighting installation that measures over one footcandle on a neighboring residential lot is a Zoning Code violation the Zoning Administrator can require to be corrected, typically by adding shielding, lowering wattage or redirecting the fixture, before a Building Permit, Code Compliance Certificate or Occupancy Permit is finalized for the source property.

The Bottom Line

Pasadena's outdoor lighting rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Pasadena is broadly strict or permissive.
