Renovation question for commercial building

[Stephen Kunen]

We are doing a lot of work on a 6 unit building in Allentown, PA. As of today, we realized that since we opened up walls to do the electric and plumbing work, we need to get a building permit. Because it's a commercial building, we need plans, drawings and how the work is being performed. The inspector suggests that we have a third party review the plans before we submit them. Do you have any recommendations on:

1) an architect or professional who can create the plans, drawings and description; and

2) the third party who reviews the above?

At this point, should we hire a GC to handle it? It’s putting a lot of stress on us since the scope has significantly exceeded what we planned and the handyman we normally use for the rehab work did not seem familiar with the process.

Thanks very much in advance!
