Economists across a range of political perspectives have frequently cited rent control as a policy that can discourage new rental housing construction, since developers may find capped-return properties less attractive to build. When a developer can't be confident about future rental income, some economists argue they may choose to build condos for sale instead, or invest in a different city entirely, reducing overall rental supply. Critics argue this reduced construction incentive compounds housing shortages over the long run, working against affordability goals. This tradeoff, in their view, is a critical, often overlooked cost of rent control.
