Kamala's second home in Berkeley, a 5-story "ticky-tacky" (a type of building that's the ancestor of today's 5-over-1's) at 1945 Milvia would have been a modern new building when she lived there. At that point, her mother had graduated and gotten a research job.
Today, located close to jobs and transit, and with rent control that keeps rent stable, these 4-5 story ticky-tacky apartments remain popular with recent graduates in the East Bay who now have a decent income but still need to save money to afford living here.
After the 1970s, Berkeley voters banned both new 3-story boxes and the 5-story ticky-tackys, and as a result, soon found itself in a housing shortage, just as the student population shifted towards having more immigrants and their children, creating today's housing crisis.
