Basement rental conversion in Washington DC (dig-out)

[Ricardo James]

I'm looking to convert my Brookland DC row house basement to a legal rental unit , I was wondering if anyone has done this, what was the cost?

My ceiling height is 6'2 in the front and 7'5 in the back of the house, so I know I'll need to do a dig-out.   Any input, suggestions or recommendations (Architect, Contractor, etc.) that the BP forum may have for me moving forward with my basement conversion project would be great for me and anyone else with the same question here on the forum. 

Please feel free to inbox me with contacts 

Thanks

Ricardo
