Welcome to our forum.
he said the new code states that some barrier needs to be put down per new code.
When I put in my hot tub 4 years ago I pulled my permit for the electrical installation but needed a special "spa permit" for $35. It had no requirements just a $35 charge. The city is in need of money so they added it to the list of permits.....if fact if you change washers in a faucet you are suppose to get a permit As funding goes down for cities permit requirements go up
