So it is with affordable rentals. My 1900 single family split-entry house is now, functionally, a cross between a triplex and housemates. The build-it way of affordable rentals looks so inadequate to the need, and so expensive now for materials, that turning a family house into a 2 or 3 suites house is the tasty low hanging fruit of a solution. Please share this widely to help spread the idea, and possibly create rentals where there are none – and quickly. There are other measures that require the government – squeezing out short-term rentals, changes in codes and permitting – but this is classic American DIY.
