Hi Mario,I am an investor and architect here in Buffalo, NY.

Have inspector look for typical inspector stuff but also bring in a structural engineer/architect or maybe even just a contractor to look over the building for structural failures.

I am only a regular person, so I am missing lots of info involving code, where the best place to put lighting fixtures, how to design/modify plumbing, etc.Things I need: 1) to know best place to put electrical wiring, etc 2) to know the best place to put plumbing, etc 3) how to situate everything in bathroom and kitchen area... 4) advice periodWould a residential architect handle these things?

But yes, if it meets the ADU definition, you could market the house as having a legal basement ADU, and that should have some value on the market.There are some architects in DC who do a lot of ADUs and particularly English basement units; since the building code is almost identical, I'm sure they'd be well versed in the code particulars.

The delays in remapping the flood zones by FEMA, in combination with a business partner fallout, as well as having several GCs and architects incorrectly submit permits and plans for approval resulted in a VERY drawn-out project.

I have build homes and office buildings, garages etc from drafting drawings to working with city and government officials, engineers, architects and finally moving people in.I am a disabled Veteran, But I am not asking for a hand out, Just a leg up to get going. 

Little background, I'm an architect with two single family properties each zoned for 4 units in Berkeley.

I've always believed architect as designer and developer made the most sense, and for me it's about having design freedom to create better spaces that are not purely financial and developer driven.  

Developers develop property by buying the property having designers and architects draw up the plans then hire a general contractor who performs the construction side of the work.  

We buy properties in high demand areas, Work in areas where there's a strong economy (more qualified buyers/investors) Buy land priced at or below market value, Design as cost effective of a project as possible,Shop everything for the best price and highest workmanshipList our own properties (and sometimes sell ourselves)Act as our own general and electrical contractors, Do all preliminary architectural and site design in houseStay involved with engineers, architect, planners, etc.Understand the entire permitting process, and build relationships.
