Round 80

Housing Reform Package

A city council must choose a policy package to address rising rents, low vacancy rates, and displacement pressure while preserving neighborhood character and fiscal stability. The city can influence zoning, tenant protections, and subsidies, but it faces a limited budget, legal constraints from state law, and concerns about slowing private development. The goal is to increase housing supply and affordability within 5 years without causing major political backlash or concentrating harm on lower-income renters. Tradeoffs include speed versus durability, market incentives versus direct regulation, and citywide consistency versus neighborhood-by-neighborhood tailoring.
