LSA Announcements

December 2025

• We have passed the Initial Review of Warning Flags milestone in the FY2025 LSA Season. Data Quality - Missing Elements flags have been impacting many communities. Vendor-level advocacy for additional information, resources, and increased thresholds has continued. 
  The list of new flags are outlined below:  
   

  Category	Flag ID	Flag Description
  LSAPerson File	1351	RaceEthnicity is missing for more than 1% of people in this project type and household type. Please review enrollment data for this project type and household type to check if any missing Race/Ethnicity data can be updated for adults and Head of Households. "Missing" is defined to mean data where the related field(s) in HMIS has a value of 99 (i.e., "Data Not Collected"), is null, or is blank.
  LSAPerson File	1352	DisabilityStatus is unknown for more than 10% of adults and Head of Households in this project type and household type. Please review enrollment data to check if any unknown Disability data can be updated. Disability data is considered unknown when the "Disabling Condition" question has a response of "Client doesn't know," "Client prefers not to answer," or "Data not collected" or when the field is null or blank in HMIS.
  LSAPerson File	1353	DVStatus is missing for more than 10% of adults and Head of Households in this project type and household type. Please review enrollment data to check if any missing DV data can be updated. DV data is considered missing when the "Survivor of Domestic Violence" question has a response of "Data not collected" or is null or blank in HMIS. Per the HMIS Data Standards, Domestic Violence (4.11) is a Common Program Specific Data Element, and not all projects are required to collect this data based on the project's funding source. If this is a contributing factor to the missing percentage in this flag, please reference this in your note.
  LSAHousehold File	1354	HoHRaceEthnicity is missing for more than 1% of Head of Households in this project type and household type. Please review enrollment data for this project type and household type to check if any missing Race/Ethnicity data can be updated for Head of Households. "Missing" is defined to mean data where the related field(s) in HMIS has a value of 99 (i.e., "Data Not Collected"), is null, or is blank.
  LSAHousehold File	1355	ESTLivingSituation is missing or invalid for more than 5% of households of this household type. Please review enrollment data to check if any missing or invalid Prior Living Situation data can be updated. Prior Living Situation is considered missing or invalid if the "Type of Residence" question has a response of "Data not collected" or is null or blank in HMIS. Also included as missing are cases where the Type of Residence is "Rental by client, with ongoing housing subsidy" and the Rental Subsidy Type field is null or blank in HMIS. (Note that EST project types include Emergency Shelter, Safe Haven, and Transitional Housing.)
  LSAHousehold File	1356	PSHLivingSituation is missing or invalid for more than 5% of households of this household type. Please review enrollment data to check if any missing or invalid Prior Living Situation data can be updated. Prior Living Situation is considered missing or invalid if the "Type of Residence" question has a response of "Data not collected" or is null or blank in HMIS. Also included as missing are cases where the Type of Residence is "Rental by client, with ongoing housing subsidy" and the Rental Subsidy Type field is null or blank in HMIS.
  LSAHousehold File	1357	RRHLivingSituation is missing or invalid for more than 5% of households of this household type. Please review enrollment data to check if any missing or invalid Prior Living Situation data can be updated. Prior Living Situation is considered missing or invalid if the "Type of Residence" question has a response of "Data not collected" or is null or blank in HMIS. Also included as missing are cases where the Type of Residence is "Rental by client, with ongoing housing subsidy" and the Rental Subsidy Type field is null or blank in HMIS.
  LSAHousehold File	1358	ESTDestination is missing or invalid for more than 5% of households of this household type. Please review enrollment data for this project type and household type to check if any missing or invalid Destination data can be updated. Destination is considered missing or invalid if the "Exit Destination" question has a response of "Other," "No exit interview completed," or "Data not collected" or if the field is null or blank in HMIS. (Note that EST project types include Emergency Shelter, Safe Haven, and Transitional Housing.)
  LSAHousehold File	1359	PSHDestination is missing or invalid for more than 5% of households of this household type. Please review enrollment data for this project type and household type to check if any missing or invalid Destination data can be updated. Destination is considered "missing or invalid" if the Exit Destination field in HMIS is blank or has a value of "Other," "No exit interview completed," or "Data not collected".
  LSAHousehold File	1360	RRHDestination is missing or invalid for more than 5% of households of this household type. Please review enrollment data for this project type and household type to check if any missing or invalid Destination data can be updated. Destination is considered "missing or invalid" if the Exit Destination field in HMIS is blank or has a value of "Other," "No exit interview completed," or "Data not collected".

  • Please note, these flags may also appear without these missing elements if enrollments occur outside of Program Operation Dates, HMIS Participation Status Dates, and/or when an ES NbN Enrollment program start/exit date differs from the First Bed Night/Last Bed Night +1 day. This is due to how the LSA specifications adjust start/exit dates. When adjusted start or exit dates do not align with the HMIS start/exit dates, it can cause these flags to return (particularly for LivingSituation, Destination, and Disabling Condition flags). 
    
    • In the context of ES NbN enrollments and clients, it is important to recognize that ESTDestination flags may occur in the absence of an Exit Date one day after the last recorded Bed Night. This situation may result in a community surpassing the threshold related to the project and household type. In such cases, the LSA establishes an effective Exit Date with an Unknown (99) Destination.
• We are approaching the December 15, 2025, Initial Review of Warning Flags interim benchmark. By this date, each CoC should have at least one Official HUD Review file successfully uploaded with all applicable notes entered.
