Outdoor Lighting in San Francisco, CA: What Residents Actually Need to Know

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

Light Trespass

Light trespass from one property onto another is addressed under San Francisco's nuisance provisions and Planning Code lighting requirements. New construction and renovations must direct outdoor lighting downward and away from adjacent properties.

Key details: Regulation: Planning Code + nuisance provisions. Requirement: Lighting must not spill onto adjacent properties. Complaints: File through SF311 or Planning Dept. Standard: CALGreen property boundary limits apply.

Light trespass complaints may be addressed through code enforcement or nuisance abatement. The Planning Department may require lighting modifications during project review or in response to complaints.

Dark Sky Rules

San Francisco does not have a standalone dark-sky ordinance, but the Planning Code and Building Code regulate outdoor lighting to minimize light pollution and glare. The city's Green Building Code includes lighting efficiency standards that indirectly reduce sky glow.

Key details: Dark-Sky Ordinance: No standalone ordinance. Shielding: Downward-directed and shielded required. State Code: CALGreen outdoor lighting standards apply. Green Building: Energy-efficient fixtures required. Enforcement: DBI and Planning Department.

Non-compliant lighting may result in code enforcement action by DBI or Planning Department. Excessive glare or light trespass complaints can be addressed through the nuisance provisions of the Police Code.

The Bottom Line

San Francisco'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 San Francisco is broadly strict or permissive.

These rules come from San Francisco's publicly available municipal code. For complete penalty schedules, exemption details, and answers to common questions, see the individual ordinance pages throughout this guide.
