Adding sqft to a home

[Adam Spencer]

Hi,

  I recently had my basement remodeled and added about 890 sqft of living space.  The main intent was to make a 1bd apt for my retired parents to have a nice inexpensive place to live.  Anyway, I now have a bigger house and want to refi and am curious how the process goes for adding square footage. Do I want to contact the city to have it changed? Or would an appraisal accomplish this? Also, I need recommendations on an appraiser in or near Ypsilanti, MI.
