WAC 296-832-30015. Provide outside lighting

You must light the store's approach area and parking lot during all night hours your business is open. Note: You can do this by: 1. Providing surveillance lighting to observe pedestrian and vehicle entrances. 2. Providing lighting of a minimum of one foot candle to comply with ANSI/IES RP7-1983. Lighting levels can be measured with a light meter; for comparison purposes 1 foot-candle = 1 lumen incident per square foot = 10.76 lux.
