I was listening to an audiobook and was annoyed with one of the prescriptions that authors are forced to tack on to their books. Housing was a background issue. It would have made more sense if the prescription was unionizing, not touting zoning for more multifamily housing, a topic explored at the 11 hour.
What annoyed me was, after working on the history of this neighborhood, that a historical solution that worked was ignored. Boarding houses and taking in boarders. Many people in Truxton Circle, homeowners and renters, had boarders.

However, this very low rung in the housing is almost illegal. Like mobile homes (another affordable housing product illegal in many municipalities), the laws on the books make such a thing impossible to run legally. There are illegal boarding houses in DC. We find out about them when someone dies in a fire.
We’d prefer someone to live in a tent in a park, then have a house with all sorts of people coming in and out, where people live for cheap. I’m not going to romanticize boarding houses either. Poorly run ones were a nuisance. But, they were a roof over a person’s head. Four solid walls (maybe thin walls) where they could call home.
Back when I was in elementary school and at an age where we made friends easily, I had a ‘friend’ who lived in a boarding house near the school. Her family, mother, father and maybe a sibling, all lived in a room in the back of this 2 story frame house that no longer exists. I remember the room being poorly lit & junky. This was a working class Black neighborhood, and if you couldn’t afford to rent a whole house or get into the public housing, well you were pretty bad off.
The author, like Jane Jacobs, assumed a type of housing would make it affordable. Jacobs believed older housing was affordable. I’m in my youngest house, built in 1940, cheap is the last word I’d use to describe it. And likewise, there are multi-unit houses, houses carved up into condos, that are out of the price range for most. Even if DC allowed people to live in converted Home Depot sheds on land they rented or owned, the prices will find a way to jack up.
Okay. Rant over.
