How Sioux Falls Handles Outdoor Lighting: A Practical Guide
Sioux Falls maintains 135 local ordinances across all categories, and 3 of those deal specifically with outdoor lighting. Here is a breakdown of what the city actually requires, what is prohibited, and where Sioux Falls falls on the strict-to-permissive spectrum compared to other cities.
Light Trespass & Shielding
Sioux Falls requires fully shielded, cutoff fixtures for security lighting and other outdoor lights exceeding 2,220 lumens within 150 feet of residential property or a street right-of-way, capping fixture height and light trespass under the city's zoning ordinance.
Key details: Shielding trigger: >2,220 lumens within 150 ft. Max fixture height: 28 ft near residential property. Light trespass cap: 3 foot-candles at property line. Banned light source: Low-pressure sodium lamps. Grandfathered: Fixtures installed before 9/28/2006.
Violations default to the city's general penalty: up to a $500 fine, 30 days in county jail, or both, with each day of noncompliance a separate offense under § 10.999.
Dark Sky Rules
Sioux Falls requires full-cutoff, fully shielded fixtures for bright outdoor lights near homes and streets, and caps fixture height and light spilling across property lines.
Key details: Shielding trigger: >2,220 lumens within 150 ft. Light trespass cap: 3 foot-candles at property line. Max fixture height (near residential): 28 feet. Max fixture height (farther out): 38 feet. Banned light source: Low-pressure sodium.
Enforced by the city Zoning Officer through the building/lighting permit process; noncompliant plans are denied, and fixture or lamp substitutions require prior Zoning Officer approval before installation.
Billboard Lighting
Sioux Falls requires off-premises sign (billboard) illumination to be shielded from neighboring property and bans blinking or flashing lights, limiting electronic message changes to six-second intervals.
Key details: Shielding required: Must not affect neighboring premises or drivers. Blinking/flashing: Prohibited. Message change rate: No faster than every 6 seconds. Animation: Prohibited; message must be static. Default penalty: Up to $500 fine / 30 days jail.
Violating the shielding, blinking/flashing, or message-frequency rules is a Code violation; absent a specific penalty, § 10.999 sets a fine up to $500 and/or up to 30 days in the county jail, with each day of continuing violation a separate offense.
The Bottom Line
Sioux Falls'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 Sioux Falls is broadly strict or permissive.
