2013-2021 Housing Element Data


Main Data Tables Workbook

The Microsoft Excel Workbook linked below contains 14 worksheet tabs with 34 different data groups in the form of tables. Data is provided at the jurisdiction and County level. The first tab ‘read me’ contains the master reference list of data items; subsequent labeled tabs contain the data summaries from the Census and other sources for many of the items required to be examined in the housing element update.

SACOG is also working on data related to the farmworker population, and will notify jurisdictions when that data is posted. Other data that can be downloaded separately are described below.

Housing Element Data Profiles (updated Dec. 10, 2012)

Information on Developmental Disabilities 

Chapter 507, Statutes of 2010 (SB 812), which took effect January 2011, amended State housing element law to require the analysis of the disabled to include an evaluation of the special housing needs of persons with developmental disabilities. This analysis asks jurisdictions to include an estimate of the number of persons with developmental disabilities, an assessment of the housing need, and a discussion of potential resources. A “developmental disability” is defined as a disability that originates before an individual becomes 18 years old, continues or can be expected to continue indefinitely, and constitutes a substantial disability for that individual. This includes Mental Retardation, Cerebral Palsy, Epilepsy, and Autism. The following table was created from information collected from Alta Regional Center, the non-profit that serves individuals and families of those with developmental disabilities in the SACOG region.

Information on Subsidized Units 

As a part of the work for our HUD grant, SACOG staff also compiled information from a number of sources to build an inventory of public housing units and affordable rentals built with some form of public subsidy in each jurisdiction. The spreadsheet below contains the total number of units in each building, the number that are subsidized, and the source of the information by address. The inventory was compiled from federal, state, and jurisdiction information.

Information on At-risk Units 

SACOG staff also compiled information obtained from the California Housing Partnership Corporation on subsidized rental housing at risk of conversion to market rate. The spreadsheet below contains data for each jurisdiction on units at risk by year.

RHNA Tables 

The adopted 2013-21 Regional Housing Needs Allocation Plan contains two tables showing allocations. Table 2 is exactly the same one that was adopted in the RHNP and it shows how the RHNA methodology calculates each allocation.

However, the other table, Table 1 below, has been slightly modified: this now shows the amount of Extremely Low Incomes (ELI) by jurisdictions. The ELI category is defined as households that have incomes that are below 30% of the median family income for their county. The Very Low Income (VL) category is then defined as households that have incomes that are between 30%-50% of the median family income for their county. Table 1 was determined by dividing each jurisdiction’s Very Low Income (VLI) in the RHNP in half, where half of the allocation goes towards ELI and half goes to VLI. The ELI is calculated because Government Code Section 65583(a)(1) states that for projected housing need local governments may either use available census data to calculate the percentage of very low income households that qualify as extremely low income households or presume that 50 percent of the very low income households qualify as extremely low income. We split the very low allocation in half. Half is allocated to extremely low income (EL) and half is allocated to the original very low (VL) income category. A jurisdiction’s total allocation does not change.

Foreclosure Information 

AB 1103 (Chapter 210 in 2011), added a provision that allows jurisdictions to count foreclosed homes and second units converted into deed-restricted affordable homes toward up to 25 percent of their regional housing needs assessment requirement if they meet specified requirements. SACOG can provide summary reports of historic foreclosures in each jurisdiction and/or summary information on the number of properties under notice of default in specific planning areas.

Information on Farmworker Data 

State housing element law requires localities to analyze the housing needs of special populations, including farmworkers. The memo below, prepared by SACOG staff, provides information and tables from farmworker data sources to help jurisdictions assess data available for their use.

Assessment of Regional Farmworker Data (Updated January 22, 2012)

SACOG has gathered or prepared the following resources for use by cities and counties to assist with their housing element updates:

HCD Data Approval Letter: As noted above, the housing element data collected by SACOG has been reviewed and approved by the California Housing and Community Development Department (HCD). The first attachment is HCD’s letter (dated January 30, 2013) stating that any data from this source cited in your jurisdiction’s housing element has already been approved and will not need further review. Please be sure to include a copy of this letter in your housing element draft.

HCD Guidelines: These are the final version of the Housing Element guidelines released by HCD in December.

Local Government Density Analysis Template:: One local government has prepared a template for how to structure a lower income housing density analysis. This provides some guidance from a local government’s standpoint on what should be included in the analysis. This document has been reviewed by HCD staff and determined to be a useful template.

Built Densities Inventory: An inventory collected by SACOG of built affordable housing projects with actual densities in the region has been updated on January 18, 2013. This information was provided by participating local governments.

Successful Density Analysis Examples: HCD has compiled examples of lower income density analyses that were determined to be acceptable from seven jurisdictions throughout California. These jurisdictions were allowed to use lower densities than the statutory default densities. The first five examples (Lake County, Apple Valley, Fairfield, Lake Elsinore, and Murietta) provide overall density analysis, while the remaining two (Solano County and Yolo County) address specific issues (e.g, farmworker housing, second units).
