🏘 Identifying Rental Properties in Richmond, CA
Community Land Trusts (CLTs) like Richmond LAND aim to address the affordable housing crisis through community-controlled land acquisition and housing development. CLTs have limited resources for parcel acquisition; therefore, it is important to understand the landscape of rental properties to inform Richmond LAND policy making decisions. We wanted to identify characteristics correlated with existing rentals
Research Question
What characteristics – community, demographic, and physical housing characteristics – best predict whether a property is a rental in Richmond, CA?
Data Sources
- Richmond LAND-provided parcel dataset, a combination of Richmond City Parcel Data, Rent Board Data, and organization data
- Census Tract demographic data
- Zillow API Parcel Data
Methods
- Limit dataset to Residential Parcels in Richmond using ArcGIS
- Created geospatial variables/features such as zone, neighborhood identifiers, distance to Parks, Schools, and Toxic Waste Sites.
- Created definition of “Rental Property” based on available characteristics:
- Landlord ID exists
- Site Address that does not match Owner Address, or
- Rent Board Status indicates Owner Occupied or Outside City Boundaries
- Number of Units Owned by Landlord less than a certain threshold
- Linked parcels to ancillary variables: housing characteristics from Zillow, community infrastructure, and Census Tract demographics/income
- Identified variables that differ between rental and owner-occupied
- Calculate correlations and odds ratios between these variables using logistic regression
Conclusions
Several characteristics stood out as statistical differentiators of rental vs. owner-occupied housing. Among the strongest were municipal zones: parcels located in commercial or medium-to-high density zones were more likely to contain rentals. Additionally, we identified five specific neighborhoods that were more likely to contain rental housing.
Demographic characteristics also were predictive of owner-occupied housing: typically these were in Census tracts with a higher white population and increased income.
