The Anti-Eviction Lab brings together spatial, racial, and technological justice collective projects with student researchers. Housed at University of Washington and led by Erin McElroy, it prioritizes collaborative knowledge making with groups such as the Anti-Eviction Mapping Project, including its Evictorbook project.

One of its current focuses is Landlord Tech Watch aimed at producing scholarship, oral histories, and popular education materials related to the property technology industry. We are also now working on building Proof in Numbers and the Rental Ripoff Portal to empower tenants and tenant unions in New York City and beyond.

As of 2025, the lab is also engaging in a study of technolibertarian cities globally, as well as geographies of political software.

Our lab aims to produce interdisciplinary research and public facing scholarship related to intersections of eviction, technology, surveillance, and gentrification, all with an aim of supporting on-the-ground housing justice struggles.

One of the lab’s current focus is on surveillance technologies, tenant screening algorithms, and property management software deployed in throughout the US, with a focus on California, New York, Washington, and Texas. We are also looking at older 20th century histories of surveillance in tenant housing, as well as contemporary racialized and gendered outsourcing geographies of landlord technologies.

Additionally, we are invested in creating popular educational materials useful for tenants and community members in organizing against displacement. Some of this takes place in collaboration with a UW Geography class that McElroy teaches called “Gentrification, Displacement, and Housing Justice.”

Undergraduate and graduate research assistants and interns are able to learn and develop a range of skills pertinent to the project, including legal scholarship, algorithmic analysis, database creation, statistical analysis, archival studies, web and graphic design, data visualization, and more. Students have backgrounds in fields including digital studies, urban geography, urban planning, government, American studies, critical race and ethnic studies, feminist studies, design justice, and computer science. Interest in housing, racial, and technological justice is also key. If you are interested in applying to get involved, please do so here.

Proof in Numbers

PiN generates counter-data: insight gathered and governed by the dispossessed to challenge abuses that official datasets fail to illuminate.

Landlords freely deploy PropTech; screening algorithms, residential surveillance, portfolio analytics. PiN is an answer in kind, revealing the corporate landlord playbook run at scale.

Proof in Numbers is a service built by the Anti-Eviction Mapping Project, on behalf of and in partnership with the Union of Pinnacle Tenants (UPT).

Rental Ripoff Portal

The Rental Ripoff Tenant Portal is an easy-to-use dashboard & toolkit that gives you information and actionables, relevant to your unique situation.

Evictorbook

Evictorbook is a tool made by the Anti-Eviction Mapping Project that combines data on property ownership, eviction records, and corporate business filings in Oakland and San Francisco.
