The North Miami Beach council approved an ordinance Wednesday that regulates what exterior paint colors can be used in the city’s commercial zoning districts.

The ordinance, which passed on a 6-1 vote, comes as a result of what city officials call “a pattern of unsightly exterior paint colors being used and maintained,” in those areas.

Councilwoman Beth E. Spiegel was the sole vote against the ordinance.

The new paint requirements are based on Light Reflectance Value, which is a measure of the proportion of useful light reflected by a color. The range of values for LRV is from 0 percent being the most saturated to 100 percent being the lightest.

Before the ordinance, commercial properties were required to obtain a permit to paint exteriors, but the actual paint colors were not regulated.

Now, a paint sample is required for approval when pulling the paint permit and exterior paint colors must have a LRV of 35 or greater for the base of a building. The trim, which is defined as up to 20 percent of a building, is permitted to be any solid color.
