 An example of such city intent is San Francisco's "Residential Rent Stabilization and Arbitration Ordinance" (SFRO), enacted in 1979 as an emergency ordinance amending the San Francisco Administrative Code.It found that, in the face of tight markets and significant rental increases prior to rent control, "some tenants attempt to pay requested rent increases, but as a consequence must expend less on other necessities of life.This situation has had a detrimental effect on substantial numbers of renters in the City, especially creating hardships on senior citizens, persons on fixed incomes and low and moderate income households".
