During a residential inspection, the inspector notices that a bathroom has a receptacle outlet within 6 feet of the sink but it is not GFCI-protected. The homeowner claims it was installed before GFCI requirements existed. What is the correct inspection action?

Accepted Answer

Require GFCI protection as existing installations in bathrooms must comply when altered or re-inspected under current code adoption
