Ob:
I'm not up to speed on the Keystone State's 'rules' anymore, but, do you have statewide licensing?
In the Twp I work in, you can get a 100-200 resi service permit right at the counter, as long as you are licensed, seal the app, and have a check or money order.
Certificates of insurance are required for work other than minor.
Have you ran into this situation in other towns?
BTW, we always have at least one notary in the building, in the event anyone requires the services.
