Focus on cheap DIY shower heads and fancy accessories only after you’ve taken care of the basics, which is most often all about trapping rental-destroying moisture out of your walls/floors/ceilings. 

Accessory dwelling units are permitted in single families only.

Baltimore has a handful, as does Frederick.Multifamily is amongst the most competitive segment of the DC areas market due to the low amount of them that even exist (and that number is shrinking with condo conversions) and the extremely high demand of them.Montgomery County and DC allow for something called Accessory Dwelling Units.

Aaron its called an Accessory Dwelling Unit.

Rather, there is what's called an "Accessory Apartment" permit. 

Fannie Mae/Freddie Mac will not allow projected rental income (or existing rental income) to be used from a primary home unless it's a 2-4 unit property or one that has an accessory unit. 

The good thing about Tacoma is that it allows non-resident Accessory Dwell Unit (ADU) without living in it.

I spent $33,836 renovating this unit.Here's the breakdown:-Quartz Countertops: $3,500-Heat Pump System: $5,500-SS Appliances: $1,773-LVP 20 MIL Flooring: $4,406-White Shaker Cabinets: $4,000-Washer & Dyer: $400-Bathroom accessories, ceiling fans, black matte fixtures, toilets, light fixtures, faucets, etc. : $2,347-Paint, all new doors, plumbing fixtures, drywall work, garbage disposal, carpet, bathtub: $3,934-Labor: $7,976The previous owner did not do any updates to this unit for the last 25 years!

Great question - our experience has been that a DADU has to be built as an accessory structure to a home.
