What test is required to do plumbing in Harrisburg PA?

[Apartment Mike]

I am in negotiations to purchase an apartment building in the city limits of Harrisburg, PA. I have owned and operated my own construction company an hour north of the city and we have plumbed, wired and built homes for 20 years but I am told I can not do any plumbing or wiring on my own building unless I am a licensed electrician and licensed plumber. Where do I take these tests and what is involved? Does anyone know what the process is?

You will have better luck getting an answer to this if you contact the local authorities on the licensing requirements.

In most cases you have to pass a proficiency test, AND show an extensive employment history in each of those trades. Here it is four years, substantiated with either affidavits from previous employers or payroll stubs.
