Residential Lighting Requirements

Property Boundaries and Light Trespass

North Mankato takes neighbor relations seriously with specific limitations on light spillover. Reflected glare or light from private exterior lighting cannot exceed 0.5 footcandles when measured at property lines abutting residential parcels, and 1 footcandle when abutting commercial or industrial parcels.

Exterior Lighting Direction

The regulations clearly state that any lights used for exterior illumination shall be directed away from adjacent properties. This simple but important rule helps maintain neighborhood harmony while still allowing property owners to adequately light their premises.

Sensory-Accessible Dwelling Units

For specialized housing accommodations, North Mankato prohibits the use of fluorescent lighting in sensory-accessible dwelling units and their common areas. This regulation recognizes the sensory sensitivities that some residents may experience.

Commercial and Multi-Family Lighting Standards

Parking Area Illumination

Safety is a priority in North Mankato's commercial areas. The code requires:

• Commercial, industrial, and multi-family parking areas must be sufficiently illuminated during hours of operation
• Lighting must protect the safety of properties, vehicle operators, and pedestrians
• All lighting must be directed away from residential properties and public streets to avoid creating a nuisance

Recycling Collection Facilities

Environmental responsibility meets safety in these regulations. Recycling collection facilities must be illuminated to ensure comfortable and safe operation if operating hours extend between dusk and dawn.

Mobile Food Vendors

The city's vibrant food scene has specific lighting limitations: No flashing, strobing or intermittent lighting is allowed for mobile food units or vendors.

Mobile Home Park Requirements

Street Illumination Standards

Mobile home parks have specific illumination requirements:

• All parts of park street systems: 0.6 footcandle minimum average maintained illumination
• Potentially hazardous locations (major street intersections, steps, or stepped ramps): individually illuminated with a minimum of 0.6 footcandle

Planning Requirements

Developers of mobile home parks must submit complete engineering plans and specifications that include the location and details of lighting and electrical systems. This ensures adequate infrastructure for resident safety and comfort.

Sign Regulations

Dynamic Display Signs in Residential Areas

Electronic signs in residential districts (R-A, R-1, R-1S, R-2, R-3, R-4) must follow these guidelines:

• Sign images can change no more than once every 3 hours
• Signs must be turned off 1 hour after sunset until 1 hour before sunrise
• Maximum luminance: 6,000 nits during daytime hours
• Manufacturer certification is required to confirm luminance control capabilities

General Sign Objectives

North Mankato's sign regulation objectives specifically mention the preservation and promotion of civic beauty, disallowing signs that would detract from this goal due to "unusual size, shape, height, location, condition, cluttering, or illumination."

Special Infrastructure Considerations

Small Wireless Facilities (SWF)

North Mankato has regulations for cellular and wireless infrastructure:

• SWFs shall not be artificially lighted unless required by the FAA or other authorities
• Lighting is permitted if the SWF is mounted on a structure primarily used for lighting
• If lighting is required, the city reviews alternatives to approve designs causing least disturbance
• Lighting must be shielded or directed to minimize glare affecting nearby properties, particularly residences

Tree Management Around Street Lights

Tree maintenance regulations recognize the importance of street lighting:

• Property owners must prune trees that overhang public property so branches do not obstruct light from street lamps
• The lowest branch must be at least 14 feet above adjacent streets, alleys, or sidewalks
• The City Forester may exempt certain trees where pruning is necessary for street light clearance

What Property Owners Should Know

Maintaining Lighting Fixtures

The city code requires that exterior light fixtures be properly maintained. No glass, including windows and exterior light fixtures, may be broken or cracked.

Prohibited Behaviors

Using a flash or spotlight in a manner that annoys or endangers others is explicitly prohibited. This regulation helps maintain community harmony and safety.

Outdoor Areas with Alcohol Service

Applications for outdoor alcohol service must include detailed information about lighting arrangements, which will be reviewed by city staff for adequacy.
