(Salem, OR) -- Oregon renters could face sticker shock in January. That's when rent could go up 14-point-6 percent. Under Oregon law, rent can increase seven-percent plus the increase in the Consumer Price Index. The total for both is 14-point-6 percent. The State of Oregon is required to publish the rate by September 30th each year. Landlords aren't required to increase rent, but many tenants are expecting that to happen. Rent for an apartment costing 15-hundred dollars a month could go up nearly 220 dollars.
