Who pulls the plumbing permit in Nampa
A separately licensed plumbing contractor normally pulls this permit in their own name, even when a general contractor holds the prime contract. The license number on the application must match the licence performing the work.
Why Nampa plumbing applications get kicked back
The most common cause is no licensed plumbing sub listed, or water heater work filed without the expansion tank and T&P discharge detail. Because the application is generated from your saved shop profile and the job scope, that field is populated before it ever reaches the counter.
