Does Building New Housing Cause Displacement?

Pennington

Main finding

New market-rate construction lowered nearby rents, displacement risk, and rent-controlled eviction notices, while also changing very local entrant composition.

Within 500m, rents fell 1.2–2.3% and measured displacement risk fell 17%

Most important limitation

The displacement proxy is imperfect, San Francisco is unusual, and this is a working paper.

Read carefully: Moving to a poorer ZIP code is an imperfect displacement proxy; San Francisco is unusual, and this is a working paper.
