Filing Fees to Add Basement Apt

What are the approximate non-construction costs to convert a basement into a legal apartment? The basement is square, cemented, and in good basement condition, but not finished as living space. Appx. 1000 sqft. Non-construction costs = architect/engineer, DOB permits, fees, required inspections, C of O filing, etc. If anyone has an estimate for the whole job, that would be helpful, but I’m really looking for the “administrative costs.” Thanks!
