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

Rent Control Policies Yield Mixed Results

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.

Abstract

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, based on quasi‐experimental and econometric approaches across diverse jurisdictions, 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.

Papers identified with Elicit search

• n = 989

Papers screened using: Intervention Type, Outcome Measures, Study Design, Geographic Context, Public/Social Housing Focus, Housing Voucher/Assistance Focus, Empirical Data, Comparison Groups

• n = 949

Papers included for extraction

• n = 40

Data Extraction

We asked a large language model to extract each data column below from each paper. We gave the model the extraction instructions shown below for each column.

• Study Design Type: Possible design types include:

  • Difference-in-differences
  • Quasi-experimental
  • Econometric study
  • Cross-sectional analysis

• Geographic Setting and Context:

  • Include country, city/metropolitan area, specific neighborhoods or regions (if applicable)

• Rent Control Policy Details: Extract comprehensive details about the rent control policy:

  • Year of policy implementation
  • Specific type of rent control
  • Key policy mechanisms
  • Scope of application

• Policy Impact Outcomes: Identify and extract the specific outcomes measured related to rent control policy:

  • Rental prices (regulated and unregulated sectors)
  • Housing supply
  • Tenant stability

• Key Quantitative Findings: Extract the primary quantitative results, focusing on:

  • Magnitude of effects
  • Statistical significance
