Getting a variance to build an addition

[Randy Dulac]

I'm not sure where I should have posted this question, but here it goes.  I want to add an addition to my personal residence, but I would need to get a variance because I will be too close to the property line.  I believe that my neighbors would be fine with us doing this work.  Obviously I would check with them before approaching the town.  I'm sure every town is different, but I am trying to see what type of objections I would get and what the likely hood of actually being able to get a variance would be.  All comments are appreciated.
