How to convert a triplex to a FourPlex?

Question

I just bought a three-story, three-unit building in Uptown Saint John NB Canada, but it has really big interior size. Based on the existing layout, I can easily convert it into fourplex with 4 pieces of three-bedroom units, each with area of 1,200 square feet. I wonder, how should I go through the procedures? I mean, should I apply for a modification permit from the city government? How do I contact local electricity company to increase one more meter on three existing meters? What else should I pay attention to? thanks for help.

As indicated in my response to your PM, I know the building well (and have one like it in the neighbourhood).  While each floor is ~1200 sqft, it will be a challenge (though not impossible) to reconfigure the building to four units ... though you might be able to segregate the ell from the remainder of the building and turn it into a multi-floor unit.

You will need a building permit to renovate that building whether you reconfigure for four units or retain it at three.  You will also need an electrical permit to have service restored to the building and may have to upgrade the entrance (we just upgraded to 400amp).

@Frank Liuh I can share with you my experience getting city permits and modifying a 4plex to 5plex. Is your building zoned for 4 units? If not, you will have to get the city to approve this. If I assume your building is zoned for 4, then you will need to get engineering drawings. Calling electrical companies is easy. Just call and tell them what you want to do. They can usually give you a basic idea over the phone of very rough cost and the steps they do. If you want quotes, they will probably sent someone out. In my area, if I upgrade the electrical, then any 'grandfather' is out the window. So if your building is currently 'grandfather' you might want to double check the cost of updating all the electrical to code. Depending on the new layout, you might be able to do the reno with min distribution to half your tenants. If you need to have an empty building, then you should account for loss rent during the time of reno. Also keep in mind you will have  '5 sets of headaches'. Good luck.
