The real solution, as you point out, is fixing the supply.  The reason the rent is too damn high is that the market has insufficient supply.  You can encourage buildings with more store frontage near the market level(s) and more housing above by offering economic incentives (possibly with conditions like rent control) until you reach a more desired outcome.<p>PS: While you&#x27;re doing this please also include civic funding mandates.  More transit, parking areas (maybe free parking transit PnRs at the edge?, better designed surface and skybridge interlinks.  Parks (public and private, maybe roof top?) as well.
