Local Lighting Codes

Rapid population growth in southern Arizona after the mid-20th century motivated  astronomers from Kitt Peak and the University of Arizona to lead an effort to establish the world’s first comprehensive outdoor lighting code (OLC) for Tucson and Pima County, adopted in 1973.

Today, Arizona is covered by many state, county and municipal OLCs (see below). OLCs are normally administered by public works or community development departments. These regulations usually start out very simple and then get more detailed with revisions about every 3 or 4 years.

If there is offensive or obtrusive lighting in your neighborhood or nearby business, we recommend you contact the property owner or management and ask if they will correct the problem. If they refuse and you believe they are in violation of a relevant lighting ordinance or code, you can file a complaint with your city or county, many of which have an online form for that purpose.

Bothered by a light in your community? Often, people are unaware that their lighting choices have negative impacts. Starting a conversation with a neighbor is a great way build awareness and begin the process of bringing lighting codes to your community.

If at any point you need advice or assistance, or have a specific question or concern about light pollution in your area, we are here to help.
