Adding rowhouses in Houston

Houston took this winning approach to adding housing. Could DC do the same?

Houston has used incremental infill with townhouses (in the Eugene code, rowhouses) to help add housing that is comparatively affordable without sprawling as much, showing how piecemeal densification might work. Greater Greater Washington has more.

One major benefit of these townhouses: they’re cheap! Development at this scale uses cheaper construction methods than those of large buildings, and Houston’s straightforward permitting process reduces regulatory uncertainty and thus financing costs.
