The other side o the twinhome is owned by someone else, so I'd only be changing the roof on my side.I'd like to replace the flat roof throughout the home with a sloped / skillion roof, and have the shorter side of the roof (the detached side of the home) at 9 or 10 feet instead of the current 8' height, and then obviously have the other side of the roof (the adjoining wall of the twinhome) be 15' tall.So we're essentially going to be raising the walls on all sides of the home by certain amounts, and doing a full roof replacement, changing the flat roof to a sloped roof.

One of the main obstacles to look out for here is avoiding extensions of credit to your IRA or 401k.

Keeping that in mind, I do have a great deal of admiration for those who started with huge obstacles and overcame them.

Zero impact in Toronto.. it actually fueled the real estate market lowering the interest rates.. more buyers than ever.. semi-detached "one side of duplex" minimum $800k all original 60 year old homes..

I am going to document my experience with this ADU here, so other people might find it useful.This is the exterior of the front of the house, which was remodeled in 2011-12 completely.The backyard is pretty big, and the proposed ADU is 640 sf detached from existing.The original plan was submitted and comments come back with some planning questions about size of the lot, setback requirement etc.

A large portion of these renters rent detached single family homes. 

I knew who my target market was and what obstacles I faced.
