Lighting Regulations in Farmington, Minnesota: Balancing Historical Character with Modern Illumination Standards

Introduction

Farmington, Minnesota, with its rich history dating back to its official founding in 1869, has evolved thoughtfully over time while maintaining its historical charm. As one of the first communities in the United States to offer rural free mail delivery in 1897, Farmington has long demonstrated its commitment to progressive services while honoring its heritage.

The Great Fire of 1879, which devastated much of downtown Farmington, became a pivotal moment in the city's history. This catastrophic event led to a renewed commitment to safety and careful urban planning that continues to influence the city's development decisions today—including its approach to lighting regulations.

With sixteen designated Farmington Heritage Landmarks and a population of approximately 23,000 residents, the city's lighting regulations reflect a careful balance between historical preservation, modern safety standards, and respect for neighboring properties.

For landscaping in B-1, B-2, B-3, SSMU, MUCI, MUCR, and I districts, as well as multi-family dwellings, an exterior lighting plan must be included as part of the landscape plan submission. These plans must be prepared by a qualified professional such as a registered landscape architect, registered architect, certified arborist, horticulturist, or landscape designer.

Commercial Building Lighting Standards
