Splitting up a house in Baltimore city

[M Marie M.]

Please help me understand something.

If I wanted to make a house into a duplex in DC, it's a matter of making sure the basement (and it is typically a basement) is legal in height. It is not a big deal to split a house into 2 units. Making two condo units from one SFH, that's more involved, but possible.

But I get the sense that it is a PITA in Baltimore. Is it possible to divide a house into two units, just 2, not 3, in Baltimore City? What are all the parts?

@Ned Carey might have some insight.
