IntroductionThis metadata is broken up into different sections that provide both a high-level summary of the Housing Element and more detailed information about the data itself with links to other resources. The following is an excerpt from the Executive Summary from the Housing Element 2021 – 2029 document:The County of Los Angeles is required to ensure the availability of residential sites, at adequate densities and appropriate development standards, in the unincorporated Los Angeles County to accommodate its share of the regional housing need--also known as the Regional Housing Needs Allocation (RHNA). Unincorporated Los Angeles County has been assigned a RHNA of 90,052 units for the 2021-2029 Housing Element planning period, which is subdivided by level of affordability as follows:Extremely Low / Very Low (<50% AMI) - 25,648Lower (50 - 80% AMI) - 13,691Moderate (80 - 120% AMI) - 14,180Above Moderate (>120% AMI) - 36,533Total - 90,052NOTES - Pursuant to State law, the projected need of extremely low income households can be estimated at 50% of the very low income RHNA. Therefore, the County’s projected extremely low income can be estimated at 12,824 units. However, for the purpose of identifying adequate sites for RHNA, no separate accounting of sites for extremely low income households is required. AMI = Area Median IncomeDescriptionThe Sites Inventory (Appendix A) is comprised of vacant and underutilized sites within unincorporated Los Angeles County that are zoned at appropriate densities and development standards to facilitate housing development. The Sites Inventory was developed specifically for the County of Los Angeles, and has built-in features that filter sites based on specific criteria, including access to transit, protection from environmental hazards, and other criteria unique to unincorporated Los Angeles County. Other strategies used within the Sites Inventory analysis to accommodate the County’s assigned RHNA of 90,052 units include projected growth of ADUs, specific plan capacity, selected entitled projects, and capacity or planned development on County-owned sites within cities. This accounts for approximately 38 percent of the RHNA. The remaining 62 percent of the RHNA is accommodated by sites to be rezoned to accommodate higher density housing development (Appendix B).Caveats:This data is a snapshot in time, generally from the year 2021. It contains information about parcels, zoning and land use policy that may be outdated. The Department of Regional Planning will be keeping an internal tally of sites that get developed or rezoned to meet our RHNA goals, and we may, in the future, develop some public facing web applications or dashboards to show the progress. There may even be periodic updates to this GIS dataset as well, throughout this 8-year planning cycle.Update History:1/7/25 - Following the completion of the annexation to the City of Whittier on 11/12/24, 27 parcels were removed along Whittier Blvd which contained 315 Very Low Income units and 590 Above Moderate units. Following a joint County-City resolution of the RHNA transfer to the city, 247 Very Low Income units and 503 Above Moderate units were taken on by Whittier. 10/16/24 - Modifications were made to this layer during the updates to the South Bay and Westside Area Plans following outreach in these communities. In the Westside Planning area, 29 parcels were removed and no change in zoning / land use policy was proposed; 9 Mixed Use sites were added. In the South Bay, 23 sites were removed as they no longer count towards the RHNA, but still partially changing to Mixed Use.5/31/22 – Los Angeles County Board of Supervisors adopted the Housing Element on 5/17/22, and it received final certification from the State of California Department of Housing and Community Development (HCD) on 5/27/22.

The unincorporated areas have been assigned a RHNA of 90,052 units for the 2021-2029 Housing Element planning period, which is subdivided by level of affordability as follows:Very Low Income – 25,648Lower Income – 13,691Moderate Income – 14,180Above Moderate Income – 36,533The Sites Inventory (Appendix A) is comprised of vacant and underutilized sites that are zoned at appropriate densities and development standards to facilitate housing development. Other strategies to accommodate the RHNA include projected number of ADUs, specific plan capacity, selected entitled projects, and capacity or planned development on County-owned sites within cities. The remainder of the RHNA is accommodated by sites to be rezoned to accommodate higher density housing development.MORE DETAILED INFO ON METHODOLOGY: ((PLACEHOLDER for Appendix G from BOS Consent posting))UPDATE HISTORY:1/5/21 - Coded Supervisorial District for each parcel2/4/21 - Added four fields that show the proposed / existing Land Use Policy / Zoning that display the category + brief description + density range - done mainly for the Story Map. Also, renamed the GIS layer (removed 'Adequate_Sites_Inventory' from the name).3/16/21 - Added 'Status Update (2021)' field to flag those parcels for removal following findings from Housing Section and EIR consultant.3/31/21 - Began making edits based on QC done by Housing Section in March, 2021 and exported this layer to an ARCHIVE version so we have the original data if needed. Made the following updates in AltadenaCoded all 'GC' categories as 'N/A' for RHNA Eligible and removed proposed LUP / Zoning category - THESE CAN NO LONGER BE COUNTED IN REZONE.Downgraded Proposed MU to Proposed CG for all current 'MU / Commercial Zones', and updated min/max density. Nulled out proposed zoning categories. Need to re-do unit calculations!4/1/21 - Continuing with Altadena QC, updating Status Update (2021) field:Downgraded Proposed MU to Proposed CG for all current 'MU / Non-Commercial Zones', and updated min/max density. Need Proposed Zoning from HE Section for consistency with CG category. Need to re-do unit calculations!Coded the ones marked 'Zoe to review'4/4/21 - Coded additional parcels that were condos (missed from before). Updated '2021 Update notes' and condo-related fields (including units). In Altadena, re-calculated units for all that are downgraded from Prop LU MU > CG. Identified those not meeting 16 unit minimum, and of those that were RHNA eligible, were coded as 'No'. Noted in the '2021 Update notes'.4/5/21 - Made the following edits per QC results from Housing Section:Lennox / W. Athens - coded '65 dB' parcels as "N/A" (removing from Rezoning list).Altadena - verified that no additional RHNA eligible parcels removed due to the criteria: “Existing residential buildings 50 or more years old, where the number of units allowed under the new LU is at least 2 - 3 times what's on the ground”All areas - coded Density Bonus of 27.5% as identified from the Housing Section as blank4/6/21 - Continued making edits per the QC results from Housing Section from the Rezoning list.4/7/21 - Continued making edits per the QC results from the Housing Section for Altadena.4/10/21 - Double-checked all Rezone edits. Re-calculated all units for all those that were updated (Status Update 2021 IS NOT NULL) and are on Rezoning list (RHNA Eligible? <> 'N/A'). Exported RHNA eligible to spreadsheet and double-checked unit maths.4/12/21 - Updated last proposed zoning categories in Altadena (confirmed by Housing Section). Updated current / proposed zoning descriptions (removed zoning suffices).4/13/21 - Made additional QC updates to some statuses regarding parcels that overlap with ASI.4/14/21 - Updated current zoning for the recently adopted By-Right Housing Ordinance Zone Change (all of these cases have the status of "N/A" - or, not considered for rezoning)4/15/21 - Researched 11 parcels that were coded as 'Yes - Rezoning Program' for RHNA Eligibility AND were flagged as not RHNA eligible for the model runs done previously 'Filter 2b'. Confirmed they should all remain RHNA eligible with the exception of 2.4/27/21 - Updated status for additional sites during week of 4/19, and on 4/27. Updated 107 parcels to the RHNA Eligibility Status of "Yes - Moderate Income"4/28/21 - Updated 310 parcels to the RHNA Eligibility Status of "Yes - Above Moderate Income"5/4/21 - Updated RHNA Eligibility Status to "No" since it overlapped with ASI.5/5/21 - Updated RHNA Eligibility Status to "Yes - Moderate" and "Yes - Above Moderate", and also removed two parcels that were also Historical Sites, per QC requests from Housing Section. SUMMARIZED THIS DATA AS A TABLE TO RESPOND TO SUPERVISORIAL DISTRICT 1.5/11/21 - Updated schema:RHNA Eligible now just 'Yes' or 'No' (Rather than 'Yes + Inc level')Added fields for various income levels - to match what is in ASI layerKept 'Realistic Capacity' for the 'Non RHNA-Eligible' sites (these aren't broken down by Income level)Calculated 'Very Low' and 'Low' income levels to be 50/50 of the 'Realistic Capacity' (rounded up for VL, rounded down for L)5/12/21 - PREP FOR HCD TEMPLATE - Added field for Vacant / Non Vacant uses per the Assessor Use Code (ends in 'V' or 'X')6/2/21 - Updated one parcel that had 'Prop min density' blank. Trimmed Site Address field of trailing spaces.6/10/21 - ARCHIVED - exported to an archived layer as this is a snapshot in time from when it was sent to HCD on 6/7/21.6/28/21 - Exported the features (essentially copied the layer) as there was some strange behavior of attributes not selecting and joins not fully working - suspected that the data was slightly corrupted somehow, however a simple copy seemed to fix the issue. Modified several parcels per QC done by Housing Section in June, added some parcels as well.6/29/21 - Added sites per June QC and updated relevant fields - flagged those that need to have units recalculated in a temporary field.6/30/21 - Updated units for added sites. Flagged several parcels in FF and WALP for removal. RENAMED 'RHNA STATUS' CATEGORIES FROM "N/A" TO "REMOVE" (to be consistent with the ASI)7/1/21 - Removed or otherwise modified several parcels due to overlapping with new bldg permits / entitlements.7/6/21 - Updated based on refinements identified by the Housing Section on 7/1/21: Adding back Central Ave in Florence-Firestone and adding/removing sites in La Crescenta-Montrose, and updating some minor things (not related to units).7/7/21 - Checked math on all unit calculations using formulas in Excel - a small number of them were off by 1 unit (probably due to not rounding), and they were fixed. Added 'Planning Areas' field.7/20/21 - Incorporated changes following additional QC and zoning Inconsistencies identified in South and West Whittier following significant shortfall with the removal of Northlake Specific Plan:Added Income Category field and calculated valuesRemoved one parcel that overlapped with an existing Mobile Home ParkRemoved 1,122 polygons flagged as "REMOVED" that overlapped with the South and West Whittier changes (select by location against "Zoning_Inconsistancy_Parcels_SDs_345" layer.Added parcels for Above Moderate RHNA units from "Zoning_Inconsistancy_Parcels_SDs_345" layer and filled in fields as necessary.Added Adj Cluster IDs for 8 of the newly added parcels (adding to the next highest available ID in the whole dataset)7/24/21 - Coded all empty Site Addresses with nearest Street Intersection. See analysis fields starting with "Street_Intersection" in 'Housing_Element_2021_2029' File GDB.7/25/21 - Added ZIP Codes for those that were blank.7/26/21 - re-worded the metadata description (above UPDATE HISTORY)7/30/21 - 7/31/21 - Added Proposed Florence-Firestone TOD parcels.9/13/21 - Slight update to calculate the 'Income Category' field for those with RHNA Eligible = NO - to make those NULL.11/16/21 - Removed Density Bonus from the bottom 15% of sites (71 sites out of the 468) per HCD's comment. For the sites that fell below the 16 units, they were moved to the Above Moderate income category to receive RHNA credit.12/30/21 - Added updated Supervisorial District ID from 2021 update.2/17/22 - Cleared out Realistic Capacity and all income level units for "RHNA Eligible = NO". This is a clean-up measure. Kept all unit calculations for these up until the 'Realistic Capacity' field.3/15/22 & 3/16/22 - Re-allocation of income-level units per recommendation by HCD. New fields were added to indicate the original income level unit numbers (as submitted to the state following the Board Hearing), and an HCD Comments field was added to flag these parcels that changed, and the transfer of units between the income categories.SLA - move units from VL/L to Mod. Added 2,238 to Mod and subtracted 1,144 from VL, and 1,094 Low Income (lots with sf < 5,950). Checked if there were any project-specific allocations to income levels and there were none.SLA - move units from L to AM. Remaining Low Income after Step 1 is 5,819, so take approximately half of that. Selecting from pool outside of those selected in STEP 1, and lot size < 10,000sf, moved 2,566 from Low Income to Above Moderate. Checked if there were any project-specific allocations to income levels and there were none. OTHER SUBMARKET - move units from L to AM. Moved 10,031 units from L to AM (lots < 90,000 sf). NOTE, that this was most of
