Outdoor Lighting in Temecula, CA

If you live in Temecula or are thinking about moving there, outdoor lighting are one of those things you probably won't think about until they affect you directly. Temecula has 2 specific rules on the books covering different aspects of outdoor lighting, and some of them might surprise you.

Light Trespass & Shielding

Temecula requires all lighting fixtures on commercial, office, and industrial development, including spotlights, sign illumination, and parking and loading area lights, to be focused, directed, and arranged so they do not glare or shine directly onto streets or adjoining property.

Key details: Governing section: TMC § 17.08.050(D). Applies to: Commercial, office, business park, industrial districts. Standard: No glare or direct illumination on streets or adjoining property. Covered fixtures: Spotlights, sign, landscape, parking, loading lights. Enforcing body: City of Temecula Planning Division.

Temecula's Building and Safety and Planning Divisions enforce lighting standards through the development review and code compliance process rather than a standalone citation schedule. A property found out of compliance after occupancy receives a notice to correct, typically requiring re-aiming, shielding, or replacing the offending fixture. Uncorrected violations can be charged as a municipal code violation under the city's general penalty provisions, and unresolved commercial code violations can also affect renewal of a business's conditional use permit or development approval.

Dark Sky Rules

Temecula treats a violation of Riverside County's Palomar Observatory light pollution ordinance as a citywide public nuisance under Section 8.12.020, protecting dark skies near the Palomar Observatory. New residential development under the city's SB 9 two-unit rules must also shield all exterior lighting and point it downward, with no up-lighting allowed.

Key details: Nuisance citation: Section 8.12.020(A). Incorporated ordinance: Riverside County Ordinance No. 655. SB 9 developments: Lighting must be shielded, facing downward. Up-lighting: Prohibited outright for SB 9 units. Hillside zone cap: 250 lumens at property line.

A light pollution nuisance under Section 8.12.020 is processed through the city's code enforcement channels: a Chapter 1.20 misdemeanor citation carrying up to a $1,000 fine and six months in jail, an infraction with fines stepping up to $100, $200 and $500 for repeat violations, or Chapter 1.24 civil penalties of up to $2,500 per day, capped at $100,000 per parcel annually, until the fixture is shielded or removed.
