developing a multifamily on lot

[Yingchun Li]

We just put a home under contract that has a huge lot, the two extra lots equal 13,224sqft.  We put it under contract because we believe that we can develop the lot into a multifamily unit.  This would be our first endeavor into developing and are seeking advice.  1st, are we allowed to build on this lot even though it has the same address for the entire lot. 2nd, if so what would be our first step to moving forward?  would we need to get a surveyor and subdivide it?
