About the Dashboard
This dashboard was developed through a six-month partnership between the LA County Affordable Housing Solutions Agency (LACAHSA) and USC Lusk’s Neighborhood Data for Social Change (NDSC) to begin providing a clearer picture of affordable housing across Los Angeles County. The ultimate goal is to build a comprehensive database that makes it easier to track and understand the county’s affordable housing supply.
LACAHSA is a regional government agency established by the California Legislature in 2022 to help increase affordable housing, protect renters, and prevent homelessness. Funded by Measure A, a countywide half-cent sales tax, LACAHSA works with the LA County Homeless Services and Housing Department to track progress toward Measure A Goal #5: increasing the number of affordable housing units throughout Los Angeles County. This dashboard will also help track that progress.
Current Production of New Rental Units
Between 2018 and 2025, 149,850 new rental units were produced across Los Angeles County. Of those, just 7,739 (5%) were considered affordable to the lowest income households in the county making less than half of area median income.
Between 2018 and 2025, the City of Los Angeles produced just over 117,000 new rental units. While the City of LA is home to approximately 40% of LA County’s population, it contained 78% of the new rental housing stock in the county across these years.
Between 2018 and 2025, 21 cities in Los Angeles County built 20 or less rental housing units each.
The data dashboard below shows new rental housing production for Los Angeles County from 2018 to 2025. This information is presented in total (on the left) and by year (on the right). Flip between the pink tabs on the top of the dashboard to view rental housing production across cities, grouped by population size, in LA County. The fourth tab shows the data grouped by LACAHSA’s 13 Eligible Jurisdictions; for information on these jurisdictions, scroll further to the next map.
Data is sourced from the Department of Housing and Community Development and is self-reported by jurisdictions. Jurisdictions may submit revisions to their annual progress report at any time. The data on this page are reflective of numbers presented by the California Department of Housing and Community Development as of July 10, 2026.
LACAHSA Eligible Jurisdictions
The data dashboard below shows the step-by-step process taken to assign city jurisdictions to LACAHSA’s thirteen Eligible Jurisdictions, as outlined in the LACAHSA FY25-26 Expenditure Plan. This information is presented in maps, moving from left to right across tabs corresponding to each step of the process. The rightmost tab displays the final Eligible Jurisdictions.
About Measure A
Funding Source
Measure A, passed by LA County voters in the November 2024 election, is a 1/2 cent sales tax to continue and grow the funding of services and housing for people experiencing homelessness in Los Angeles County.
Key Objectives
- Increase the number of people moving from encampments into permanent housing to reduce unsheltered homelessness
- Reduce the number of people with mental illness and/or substance use disorders who experience homelessness
- Increase the number of people permanently leaving homelessness
- Prevent people from falling into homelessness
- Increase the number of affordable housing units in LA County
Implementation
Generating over $1 billion annually, Measure A funding will be shared by LA County Cities and Councils of Government (COGs), the Los Angeles County Development Authority (LACDA), and the Los Angeles County Affordable Housing Solutions Agency (LACAHSA). LACAHSA is a body made up of leaders including the LA County Supervisors, elected officials representing cities countywide, as well as nonprofit and community leaders.
This project was made possible through support from the Los Angeles County Affordable Housing Solutions Agency.
