San Diego has been named the most expensive place to live in the United States, according to U.S. News & World Report. The city has a high cost of living due to expensive housing, fees such as homeowners association dues, and the region's desirable qualities, such as its year-round temperate climate. Prices in the region have increased by about 4.7% over the past year, exceeding the national average, and rent has increased by 8.8%. This highlights the need for solutions to address housing affordability in the region.
