There is a consensus among economists that rent control reduces the quality and quantity of housing. In a 2013 analysis of the body of economic research on rent control by Peter Tatian at the
Urban Institute (a
think tank described both as "liberal" and "independent"), he stated that "The conclusion seems to be that rent stabilization doesn't do a good job of protecting its intended beneficiaries—poor or vulnerable renters—because the targeting of the benefits is very haphazard.", and concluded that: "Given the current research, there seems to be little one can say in favor of rent control." Two economists from opposing sides of the political spectrum,
Nobel Laureate Paul Krugman (who identifies as an American liberal or European
social democrat), and
Thomas Sowell, (who stated that "
libertarian" might best describe his views) have both criticized rent regulation as poor economics, which, despite its good intentions, leads to the creation of less housing, raises prices, and increases
urban blight. Writing in 1946, economists
Milton Friedman and
George J. Stigler said: "Rent ceilings, therefore, cause haphazard and arbitrary allocation of space, inefficient use of space, retardation of new construction and indefinite continuance of rent ceilings, or subsidization of new construction and a future depression in residential building." Historically, there have been two types of rent control – vacancy control (where the rent level of a unit is controlled irrespective of whether the tenant remains in the unit or not) and vacancy decontrol (where the rent level is controlled only while the existing tenant remains in the unit). In California prior to 1997, both types were allowed (the Costa/Hawkins bill of that year phased out vacancy control provisions). A 1990 study of Santa Monica, CA showed that vacancy control in that city protected existing tenants (lower increases in rent and longer stability). However, the policy potentially discouraged investors from building new rental units. A 2000 study that compared the border areas of four California cities having vacancy control provisions (Santa Monica, Berkeley, West Hollywood, East Palo Alto) with the border areas of adjoining jurisdictions (two of which allowed vacancy decontrol, including Los Angeles, and two of which had no rent control) showed that existing tenants in the vacancy control cities had lower rents and longer tenure than in the comparison areas. Thus, the ordinances helped protect the existing tenants and, therefore, increased community stability. However, there were fewer new rental units created in the border areas of the vacancy controlled cities over the 10-year period. A study that compared the effects of local rent control measures (both vacancy control and vacancy decontrol) with other local
growth management measures in 490 California cities and counties (including all the largest ones) showed that rent control was stronger than individual land use restrictions (but not the aggregate effect of all growth restrictions) in reducing the number of rental units constructed between 1980 and 1990. The measures (both rent control and growth management) helped displace new construction from the metropolitan areas to the interiors of the state with low income and minority populations being particularly impacted. In 1994, San Francisco voters passed a
ballot initiative which expanded the city's existing rent control laws to include small multi-unit apartments with four or less units, built prior to 1980 (about 30% of the city's rental housing stock at the time). In 2017,
Stanford economics researcher
Rebecca Diamond and others published a study which examined the effects of this specific rent control law on the rental units newly controlled compared to similar style units (multi-unit apartments with four or less units) not under rent control (built after 1980), as well as this law's effect on the total city rental stock, and on overall rent prices in the city, covering the years from 1995 to 2012. They found that while San Francisco's rent control laws benefited tenants who had rent controlled units, it also resulted in landlords removing 30% of the units in the study from the rental market, (by conversion to
condos or
TICs) which led to a 15% citywide decrease in total rental units, and a 7% increase in citywide rents. The authors stated that "This substitution toward owner occupied and high-end new construction rental housing likely fueled the gentrification of San Francisco, as these types of properties cater to higher income individuals." The authors also noted that "...forcing landlords to provide insurance against rent increases leads to large losses to tenants. If society desires to provide social insurance against rent increases, it would be more desirable to offer this subsidy in the form of a government subsidy or tax credit. This would remove landlords' incentives to decrease the housing supply and could provide households with the insurance they desire." The rental-accommodation market suffers from
information asymmetries and high
transaction costs. Typically, a landlord has more information about a home than a prospective tenant can reasonably detect. Moreover, once the tenant has moved in, the costs of moving again are very high. Unscrupulous landlords could conceal defects and, if the tenant complains, threaten to raise the rent at the end of the
lease. With rent control, tenants can request that hidden defects, if they exist, be repaired to comply with
building code requirements, without fearing retaliatory rent increases. Rent control could thus compensate somewhat for inefficiencies of the housing market. In older buildings, rent control may broaden incentives to renovate individual units: tenants may invest
sweat equity and their own money to improve their homes if they are protected from landlords trying to capture the added value, while vacancy decontrol preserves landlords' financial incentive to renovate vacant units because it allows them to re-rent at market value. According to a 2018 review of new research by Rebecca Diamond, new research showed that rent control benefitted tenants in the short-run, but had adverse effects for tenants and neighborhood stability in the long-run by reducing affordability, increasing gentrification, and creating negative spillovers for nearby neighborhoods. Landlords frequently responded to rent control policies by reconverting rentals into buildings exempt from rent control or by allowing rentals to decay. A 2019 NBER working paper, which evaluated the efficacy of different housing affordability government policies, found that better targeting of rent control (towards the neediest households) could be welfare improving. A 2021 study modelled rent control policies and found that they may raise housing prices and reduce housing quantities, but that "well-designed rent control may help policymakers to stabilize housing market dynamics, even without creating housing market distortions". ==Commentary==
