Second structure in lot, can it be a second house?

[Jonathan Tavarez]

Hi BP fam,

Recently I went to see this property seating on almost one acre and in the lot there is the main house and then a separate structure made of cinder block of around 1300 sqft (has kitchen plumbing, ceilings are around 12 feet tall, no bathroom, no electrical) and my interest in submitting an offer is the idea of making that second cinder block structure in to another house.  I check the zoning and there could be up to 5 properties in one acre so I dont think zoning will be a problem but can I really just finish up that cinder block structure and make it a house?  What things do I need to consider before I get this under contract?
