Rents are only a part of inflation measurements and can easily outpace the general rate.
California's recent rent control laws caps rent increases at 10% or 5% + the yearly CPI increase (whichever is less) every year, for example, explicitly allowing rent increases to outpace the general inflation rate. Personally, the rent I pay has gone up 9% this year.
Rents can change based on whether an area becomes more or less desirable, as insurance or other costs for landlords change, as ownership of rental units consolidates, etc.--that is, for many reasons that might be only tangentially connected or even completely divorced from the reasons that the costs of other goods and services are changing.
