The State of Nevada is being especially proactive and proposing that changes start to take effect in 2017. We’ve gathered together some of the changes that will affect every commercial pool property in Nevada and included them below for your convenience. We are predicting that these changes will soon be enacted by many other states and jurisdictions.
