Virtually everyone has used an electric range or oven in their life but lots of people have no experience at all with gas anything. 

The 8 unit has required more time and energy because it had been poorly managed for years.

Seems like it could be pretty easy to throw in an electric one, no?

The GC can handle the entire project, coordinate different subcontractors and make sure the project is completed per building codes - especially if the rehab is complex or involves multiple trades like plumbing, electrical, and carpentry.

Quote from @Miguel Del Mazo: It basically says that if the electric bill is twice what the same month's bill from last year was, the overage will be charged as a fine.That's a good barometer actually.

Bad electrical is dangerous.  

But always keep your core values front and center.I’m curious... now that you’ve got this momentum, what’s the next step you’re considering to deepen those relationships and keep the positive energy flowing?

Contractors performing structural, electrical, plumbing, or HVAC work are required to have the appropriate licenses issued by the City of Chicago.

If the home is 100 yrs old, I'm assuming it's a definite gut which is going to require new plumbing, electrical, heating, cosmetics.I spent about $140K reno on my multi family in the heights on NY ave and there were massive problems with it but it was a gut to 3 units & adding 2 bathrooms, 3 brand new kitchens 4 bathroom reno in total, all new flooring, sheetrock , insulation, framing, doors, electrical, plumbing, paint, parts of roof etc.

To avoid the risk management/insurance that comes with tenants' wood fire use:I'm thinking to seal the chimney cap on roof and run a cord putting an electric Infrared heater fireplace in there, so they can still open the glass and get heat and watch TV over the mantle, but can't burn anything or have any flame.
