As far as commercial goes you will need to do a few more inspections than residential like Phase 1 environmental, water pressure, septic, commercial building inspections and depending on the age of the buildings lead, asbestos etc. 

I have NOT included pricing for appliances.Obviously, there are a number of unknown factors that may affect final pricing but I am confident that my pricing is close.I am factoring in:Removing existing upper deck, staircase and lower deck.Replacing lower deck and stairs within permitted footprint and reducing upper deck.Having concrete foundation cut in order to install new steel door and 2 windows.Removing existing interior deck surface.Digging and removing dirt and debris to create living space as able.Bringing in a separate electrical service with all required upgrades.installing plumbing to allow for a bathroom, laundry and kitchen.I am allowing for sprayfoam to be installed as needed.Framing, boarding, taping and painting as needed.Supply and install flooring and trim.Supply and install new door and 2 windows.Remove all debris including tipping fees.Apply for and arrange for permit and inspections as required.Labour and Material as noted above - $72,000 - $76,000.00Plus HST.The next step, if you wish to proceed, is for a site visit with my electrician and plumber for sure.

DWQ, Army Corp or any other environmental requirements or permits.

I did call a few architects and only one picked up and told me he was lined up with 11 projects, all row homes, and told me to have what we want and the footprint laid out for them.

Cost of construction and footprint of land.

@Devyn CaraballoI’m in New Hampshire and our Dept. of Environmental Services has a fund homeowners can tap into to help pay for the clean up of leaking oil tanks.

If that's the case, you can't do any renovations until you have it professionally deleaded or it would be flagged for Unauthorized Deleading and you can get fined and the property would never be able to get a Lead Certificate, only a letter of Environmental Protection that states you did illegal work, got caught, then had to pay a professional to clean up the mess.

Smaller foot print, less weather issues, appeals to all skill levels, less time commitment and party/bar amenities. 

Companies are shifting to WFH, reducing their RE footprint, and shifting away from large downtown campuses, and people like having a community outside their immediate home/work circles they can go to in their local neighborhood.
