Effects of Rent Control on Housing Dynamics (public)

What are the effects of rent control policies on housing market dynamics and tenant stability?

Rent control policies yield mixed results, decreasing rents in controlled units by 4-47% and extending tenant stays by up to six years, while simultaneously reducing housing supply and increasing eviction filings, with effects varying by policy design and local market conditions.

Abstract

Rent control policies yield mixed effects on housing market dynamics and tenant stability. In regulated markets, studies report rent declines ranging from 4% to 47% in controlled units while some analyses note rent increases in uncontrolled or post‐decontrol sectors. In one San Francisco study, rents rose concurrently with a 15% reduction in housing supply and a 20% drop in tenant mobility. Other research documents tenants staying an extra six years under tighter regulation, although reports of 83–127% higher eviction filings suggest displacement risks in certain settings.

Separate analyses show shifts in market composition. For example, one study cited annual rent subsidies of about US$2440 (roughly 27% of income), and another observed reduced racial disparities accompanied by increased minority presence. These findings indicate that the impacts of rent control vary with policy design and local market conditions.

Methods

We analyzed 40 sources from an initial pool of 989, using 8 screening criteria. Each paper was reviewed for 5 key aspects that mattered most to the research question.

Paper search

Using your research question “What are the effects of rent control policies on housing market dynamics and tenant stability?”, we searched across over 126 million academic papers from the Semantic Scholar corpus. We retrieved the 989 papers most relevant to the query.

Screening

We screened in sources based on their abstracts that met these criteria:

• Intervention Type: Does this study examine rent control, rent stabilization, or rent regulation policies?
• Outcome Measures: Does this study measure at least one of the following: housing market outcomes (rental supply, housing prices, construction rates, property maintenance, market competition) OR tenant stability outcomes (residential mobility, displacement rates, tenure length, eviction rates, housing security)?
• Study Design: Is this study one of the following: randomized controlled trial, quasi-experimental design, natural experiment, longitudinal study, cross-sectional study with comparison groups, systematic review, or meta-analysis?
• Geographic Context: Was this study conducted in urban or metropolitan areas with rental housing markets?
• Public/Social Housing Focus: Is this study NOT focused solely on public housing or social housing programs without rent control components?
• Housing Voucher/Assistance Focus: Is this study NOT examining only housing voucher or rental assistance programs without rent regulation?
• Empirical Data: Is this study NOT purely theoretical or modeling without empirical data?
• Comparison Groups: Is this study NOT a case study or descriptive study without comparison groups or control conditions?
