Minnetonka, MN Outdoor Lighting: Dark Sky Rules (2026)

Section 300.28 of the Minnetonka City Code sets performance standards that apply in all zoning districts unless specifically stated to the contrary, and subdivision 2 governs exterior lighting. The code does not use the phrase dark sky. Shielding is written in terms of glare, spill light and direct off-site views of the light source.

Paragraph (b) requires mitigative measures to limit glare and spill light, both to protect neighboring parcels and to maintain traffic safety on public roads. The measures must include lenses, shields, louvers, prismatic control devices and limitations on the height and type of fixtures. Paragraph (b) also lets the city limit the hours of operation of outdoor lighting if it is deemed necessary to reduce impacts on the surrounding neighborhood. Paragraph (c) is a flat rule: no flickering or flashing lights are permitted.

Paragraph (d) bars direct, off-site views of the light source. The one exception is globe and ornamental light fixtures approved in conjunction with a site and building plan, and those are approved only when the developer can demonstrate that off-site impacts from direct views of the bulb are mitigated by the fixture design, the fixture location or both. Paragraph (e) allows the city to require a light distribution plan if deemed necessary to ensure compliance. Paragraph (a) of the same subdivision excepts street lights installed in the public right-of-way from the lighting standards.

Chapter 3 enforcement is in section 300.03 subdivision 2. A violation of a performance standard in section 300.28 means the violator must reimburse the city or its agent for the actual cost of the tests, measurements or other procedures needed to show the violation, and the city planner can start any lawful action to prevent, restrain, correct or abate it. A chapter 3 violation is also a public nuisance that can be abated under section 845 of the code.
