I really like the house but my husband didn't want to do all that work since the asking price was a bit high for the condition and the fact that it was single family, so we passed. I just got an email saying that the price dropped and we are now considering this property. Ideally, we would want to convert the 2nd floor into a separate unit and rent it and then make the 1st floor and basement a duplex for us to live in. Does anyone know how much the city charges to change the home from a single family to a 2 family? I looked on nyc.gov -homes and buildings but it doesn't list any prices for permits or a timelines. We could probably carry the mortgage for a few months, but if the construction takes a long time we don't want to go down that road.&nbsp;Thanks for the help!<br \><br \>0 replies Fri, 18 Jan 2013 17:38:00 GMT http://www.zillow.com/advice-thread/How-much-does-it-legally-cost-to-convert-a-single-family-home-to-a-2-family-home-in-11103/474908/ 2013-01-18T17:38:00Z
