Needs more information, but generally, in Baltimore City, a single-family dwelling located in a residential zoning district can only be converted to multi-family (2 or more units) in the R-7 through R-10 zoning districts.

Then you will have to switch to a homeowner/dwelling policy once repairs are made.  

But I wouldn't want to be in the business of trying to rent out bedrooms in a single dwelling. 

ADU’s Accessory Dwelling Units

While AIR will allow you to rent out a tent in your driveway, VRBO requires a separate dwelling.

In Florida, owners of townhomes and single-family residences are required to have DWELLING and WIND (HURRICANE) coverage, but you don’t have to get them both from the same carrier.

These are usually a handy man, or small time contractor job, like a contractor that regularly does turnovers for vacant dwellings and some rehab is needed.Once you get structural, involve utilities, or it's a very big job, you can appreciate why you need to let the GC get the materials themselves.

Many areas allow ADU (Accessory Dwelling Units) or In Law units, does yours?
