Quick Reference Guide: Key Lighting Requirements

Most Critical Lighting Regulations in Macon County:

• Shielding Requirements: Lighting must be shielded to prevent glare from extending beyond property boundaries
• Property Boundaries: Light from commercial facilities must not spill onto adjacent parcels
• Residential Protection: Parking area lighting must be directed away from residential properties
• Required Interior Lighting: All public halls, stairways, bathrooms, and utility areas must have electric lighting with wall switch controls
• Emergency Lighting: Battery backup fixtures required for staircases and egress in qualifying buildings
• FAA Compliance: WECS projects must utilize minimal lighting that complies with FAA regulations
• Underground Pools: Underwater lighting limited to circuits under 15 volts between conductors

Residential Lighting Requirements

Interior Lighting Standards

The Macon County building code requires certain interior spaces to have proper lighting fixtures. Every public hall, interior stairway, bathroom, laundry room, furnace room, basement, and utility areas used for storage or containing equipment requiring service must have at least one electric lighting fixture controlled by a wall switch at the usual point of entry.

Safety is a primary concern in the code, which explicitly identifies "exposed fuse blocks or cleat type light fixtures" as hazardous and prohibited.

Home Occupation Lighting Restrictions

For residents operating businesses from their homes, additional lighting restrictions apply:

• Signs for home occupations cannot be illuminated
• No equipment or process may create glare detectable to normal senses outside the property boundaries
• These restrictions help maintain the residential character of neighborhoods while allowing for small business operations

Commercial Lighting Regulations

General Commercial Properties

Commercial properties must ensure their lighting doesn't negatively impact surrounding areas. The code specifically requires that:

• Lighting should be installed for security and safety purposes only
• All lighting must be shielded to prevent glare from extending beyond the facility boundaries
• These requirements help minimize light pollution while maintaining adequate illumination for safety

Parking Area Requirements

Parking facilities have specific lighting requirements:

• All lighting used to illuminate off-street parking areas must be directed away from residential properties to avoid creating a nuisance
• For parking areas with 40 or more spaces, lights must be extinguished one-half hour after the close of business (with certain exceptions permitted by the Board)

Special Use Facilities

Certain specialized facilities have their own lighting requirements:

• Body Art Establishments: Must be well-ventilated and provided with adequate artificial light for cleaning and procedures
• Solar Energy Facilities: Lighting must be shielded and downcast to prevent light from spilling onto adjacent parcels

Wind Energy Conversion Systems (WECS) Lighting

FAA Compliance with Minimal Impact

Wind energy projects must balance safety requirements with environmental and aesthetic concerns:

• WECS Projects must utilize minimal lighting that complies with applicable FAA regulations
• Where available and FAA-approved, projects should install Aircraft Detection Lighting Systems (ADLS) or similar technology
• These advanced systems reduce light pollution and visual impacts by activating only when aircraft are detected

Monitoring and Reporting

Annual reports for WECS facilities must include information about any lighting-related complaints received and their resolution, ensuring ongoing compliance and community compatibility.

Swimming Pool Lighting Safety

Underwater Lighting Requirements

Safety is paramount for pool lighting installations:

• All luminaries (lighting fixtures) installed below the normal water level are subject to specific safety regulations
• Voltage limitation: No underwater lighting fixtures may operate on supply circuits over 15 volts between conductors
• These requirements help prevent electrical hazards in swimming areas

Street Lighting Standards

Optional Implementation with Strict Standards

While street lighting installation is optional for subdividers in Macon County, when implemented, it must meet specific standards:

• Street lights must be installed in accordance with the "American National Standard for Roadway Lighting"
• Installation must comply with the National Electrical Code
• A photometric plan showing the layout of streetlights must be submitted for approval by the Committee and County Engineer
• Performance standards must meet the City of Decatur Zoning Ordinance, § XXVIII

What Property Owners Should Know

Practical Compliance Tips

Understanding Macon County's lighting regulations helps property owners avoid violations while creating safe, attractive spaces:

• Shield All Outdoor Lighting: Direct light downward and ensure it doesn't spill beyond your property boundaries
• Consider Your Neighbors: Particularly if adjacent to residential areas, position lighting to minimize impact
• Safety First: Ensure all required interior spaces have proper lighting with appropriate switches
• Special Uses Require Special Attention: Commercial solar facilities, pools, and wind energy projects have additional requirements
• Signage Limitations: Remember that flashing lights are prohibited on signs, and home occupation signs cannot be illuminated

When Planning New Construction

For new projects, incorporate lighting considerations early in the planning process:

• Consult with local officials before finalizing lighting plans
• Include lighting details in permit applications
• Remember that lighting can affect variance approvals, as proposed variances must not impair adequate light to adjacent properties
