new construction costs for apartment buildings in LA county

[Account Closed]

Hello All,

i'm interested in the construction business and am shopping around to get $/sqft costs 

for new wood frame modern apartment buildings in mid class neighborhoods in LA county.

I only have experience in rehabilitation 

As example i take a 8000 sqft, 10 units, 2bd / 1bath, 2 story apartment building, wood frame, modern design, built on a 7000sqft flat lot with available utilities, in a mid class area in Los Angeles. Project would also include 8 covered parking spots, driveway, gate, and landscaping on 3000sqft. 

What would be the all included (engineering, permits, materials, labor,...)sqft construction cost on a $/sqft basis for the such a project excluding land? what about the time frame?

I was thinking about somewhere around $100/sqft for the building and 1 year to complete the project, but i might be wrong

thanks for any input!
