Small rent increases can add up to big burdens, analysis finds

San Francisco has rent control – rents can only go up by a certain percentage a year in buildings constructed before 1979 – but there are some costs that landlords can pass on to tenants. Tenants, in turn, may apply for an exemption by showing that the cost creates a financial hardship for them. A report from the Budget and Legislative Analyst’s office indicates that the pass-throughs individually may not seem like they amount to much, but they can add up to substantial rent increases, up to 13% in some cases.
