Full Breakdown

' The chapter exempts lighting on single-family or two-family residential sites, subdivisions and planned developments under seven principal dwelling units, street and right-of-way lighting, sign lighting, public monument lighting, and seasonal lamps under 10 watts and 70 lumens. For covered sites, a lighting plan and fixture cut sheets go to the Zoning Administrator using either the Prescriptive or Performance Method. Under the Prescriptive Method, total installed lumens are capped by the Parking Space Method or Hardscape Area Method, and every luminaire must carry a Backlight, Uplight and Glare (BUG) rating no higher than its Lighting Zone allows.

Table C-2 sets the Uplight cap at zero percent light emission above 90 degrees for street or area lighting in every Lighting Zone, and parking lot fixtures specifically 'shall have no light emitted above 90 degrees' unless ornamental lighting is approved by special use permit and still meets the Table C-1 through C-3 ratings without field modification. High-intensity uses such as searchlights, aerial lasers, sports-field lighting and correctional facilities can only deviate from these caps through an administrative deviation special use permit, which requires a signed mitigation statement and a project-specific lighting curfew.

If a site with nonconforming lighting sits abandoned 30 months or more, every fixture must be brought into full compliance before the property can be used again.

Violations & Fines

The Zoning Administrator reviews the required lighting plan and photometric calculations at permit application; fixtures that exceed the Table C Backlight, Uplight or Glare ratings or the site lumen cap are grounds to withhold permit or certificate of occupancy approval. Owners of nonconforming lighting that sits unused for 30 months or more must bring every fixture into full Chapter 4.7 compliance before resuming use. Deviations require a special use permit with a signed mitigation statement and curfew condition.

Frequently Asked Questions

Does Memphis's dark-sky lighting rule apply to my house?
No. Chapter 4.7 exempts lighting on single-family and two-family residential sites, along with subdivisions and planned developments with fewer than seven principal dwelling units. The rule targets commercial, multi-family and mixed-use development, particularly sites that abut or sit across a right-of-way from a single-family zoning district, where uplight and glare must stay within the UDC's Table C ratings.
How dark must parking lot lighting be under the UDC?
Table C-2 caps uplight at zero percent light emission above 90 degrees in every Lighting Zone, and Sub-Section 4.7.3.A.1.c independently requires that all parking lot lighting have no light emitted above 90 degrees. Ornamental parking fixtures can only exceed this if approved through a special use permit and they still meet the Table C-1 through C-3 ratings without added shielding hardware.
What happens to old, noncompliant lighting on a site?
It can keep operating until the property changes substantially. A major addition, defined as a 25 percent or greater increase in floor area, dwelling units, seating or parking, or the replacement of 25 percent or more of existing fixtures, triggers full Chapter 4.7 compliance for the affected portion. If the site sits abandoned 30 months or more, all outdoor lighting must be brought into compliance before reuse.
