In San Diego under a baseline economic scenario, the single most impactful policy is the Transit Upzoning policy; the model suggests that adopting this policy could result in almost 1.5 times as many homes as the status quo policy scenario. A Missing Middle upzone is projected to have a slightly more modest impact of about 40% above the status quo; Parking Reduction and Fee Reduction have minimal impact (7% and 6% projected increase above the status quo).
