Quick Summary

Los Angeles’s “mansion tax,” which imposes higher taxes on real estate transactions above certain price thresholds, has had adverse effects since its implementation in April 2023. The tax was intended to generate around $900 million annually but collected only about $1.2 billion in its first year. It has resulted in the loss of over 9,100 homes, including nearly 1,000 affordable units, and eliminated 16,650 full-time construction jobs. The tax also reduced high-value property sales by an estimated 31% through early 2026, leading to a significant decrease in apartment and commercial sales as well.

Story summary

The LA mansion tax, officially known as United to House LA (ULA), aimed to address the city’s housing crisis by taxing real estate transactions above certain thresholds. Implemented in April 2023, it imposed a 4% tax on sales over $5.4 million and a 5.5% tax on sales over $10.9 million. However, a new report reveals that instead of generating the expected $900 million annually, or $2.7 billion over three years, ULA brought in only around $1.2 billion, failing to meet its revenue targets by almost half.

The tax has also had unintended consequences, blocking the construction of nearly 9,100 homes and eliminating approximately 16,650 full-time jobs in the construction sector. Approximately 1,000 of these homes would have been affordable units needed to alleviate housing shortages. Additionally, ULA applies beyond luxury homes to include apartment buildings, commercial properties, and vacant land, impacting a broader range of real estate transactions than initially anticipated.

🔮 Nithya Raman’s campaign is firing back at a political group trolling her homelessness record with fake real estate signs, a rundown RV and an AI phone line impersonating the mayoral hopeful.
🔮 Billionaire developer Rick Caruso is backing his former political rival, Mayor Karen Bass, just eight days before Election Day, blasting challenger Nithya Raman’s plans for the LAPD as “reckless and dangerous.”
🔮 But despite their misgivings, Californians appear set to hand Democrats another four years in charge.
🔮 With just 11 days before voters decide the fate of Measure FD, Councilwoman Traci Park and fellow councilmembers pressed Fire Chief Jaime Moore over how the department would spend the cash, fix fire stations and get more firefighters on the streets without wasting taxpayer dollars.
🔮 Nearly eight years later, he is still living in a cramped, 350-square-foot guesthouse that survived the blaze, unable to afford the estimated $2 million it would now cost to rebuild his home.
🔮 An LA nonprofit bankrolled with millions in taxpayer funds through mayoral candidate Nithya Raman’s eviction-defense program more than tripled its revenue in five years, even as reported housing and eviction-defense spending plunged, a California Post investigation found.
🔮 Nithya Raman was back in the hot seat Tuesday night over her pledge to fire LAPD Chief Jim McDonnell, refusing to say when she’d pull the trigger as a top ally of Mayor Karen Bass blasted her for misleading voters.
🔮 Pressed about Bass’ warning that firing McDonnell ahead of the LA 2028 Olympics could be disastrous, Raman suggested waiting until 2030.
🔮 Nithya Raman has issued a word-salad denial on whether she will make controversial former District Attorney George Gascón head of the LAPD if she becomes mayor of Los Angeles.
🔮 A bombshell poll showing LA mayoral challenger Nithya Raman with a stunning 24-point lead over Karen Bass among Latino voters will loom large as the rivals face off in a high-stakes televised showdown Thursday night.
