Pool repairs are subject to permits and inspections here.
That said, not every repair complies with the above.
NJ has an annual mandatory electrical inspection for all pools other than single family resi. It is basically "visual" with GFI testing. The 'visual' on occasion turns up obvious work that was performed, like deck repairs that may have effected the equi bond.
In conjunction with the above, the pools are required to have a bonding certification & test performed every five (5) years.
