Starting Tuesday, sales taxes across Los Angeles County will rise to 9.75%, impacting local shoppers. This increase is part of Measure A, which also allocates significant funds aimed at combating homelessness. The county has approved $908 million for homeless services, including $12.2 million designated for cities in the Hahn District and over $500,000 awarded to Downey through Measure A funding. As living costs rise, residents are urged to prepare for the financial implications of these changes.
