It's hard to go from basically nothing to something very structured and expect it to take less than 20 to 30 years to get it on track. Heck some places take 12 years to update model code adoptions, yet alone get a smooth-running oversight working.
That area of PA, as those that have worked it know, was the do what you want no one really checks for over a century, then the state says here you go follow this and you can't expect the little towns to jump on board when those that live there, more than likely don't like the new rules being mandated by the state anyway.
Not saying I agree, just that until the old guard is gone, the mind set changes, and the incoming residents agree with the what the state has set in place, you will have these types of problems.
Pulling a permit in many of those jurisdictions comes with a questioner, select from the following list of third-party firms you wish to have review and inspect your project, and oh by the way, once selected, you can't change. So, pick wisely.
Since the back story is the town was not financially strong enough to stand firm, and I will guess the county can't technically step in and help, the state should have built in a problem child division, that small towns could refer back to L&I to enforce and oversee, and it comes with additional fees that accommodated being tacked on for taking over.
Call it a referral program per say. And to the problem child, our local division is not able to provide review and inspections due to the level of complexity with your project, for this reason your plans and project are being transferred to the proper state division in L&I. Call it a carrot and stick division, either work with the locals and follow the rules, or have to deal with more eyes and deeper pockets.
From what I have seen come across my desk, it is simpler and less costly to just rip down and build new, than to try and comply with converting many of the existing structures in that area.
