Rents in San Diego have decreased slightly compared to last year, with studio rents over $2,300 and two-bedroom rents around $3,700. The San Diego County Board of Supervisors is investigating the impact of private equity on housing costs, focusing on corporate ownership and potential legal actions for price-fixing and tenant harassment. Tenant groups argue institutional investment leads to unaffordable rent increases. The county is issuing more building permits to address housing affordability.
