WICHITA, Kan. (KSNW) – Changes are coming to the housing voucher program in several Kansas counties. Sedgwick, Butler, and Harvey County, excluding Newton, are moving to payment standards set by ZIP code for their housing voucher programs. In Wichita, people previously received a flat rate for their voucher. Starting Jan. 1, the amount someone receives will be based on ZIP code. The change is happening through the U.S. Department of Housing and Urban Development. Councilman Brandon Johnson is concerned about landlords who don't have good motives. OSHA proposed standards have fire departments concerned "I always think about the ways they try to get out of dealing with people, and one of those per this change is that these rates don't apply to those already under a lease or a contract," said Councilman Johnson. "It only happens when you renew or a new person enters the system." Councilman Johnson says this could allow residents to afford to live in an area with a higher median income. Officials say the change will not only be complicated to administer for city staff but will also require education for residents. That's why the city's housing department is developing a tool similar to the one already used in Boston. It lets you enter your income, bedroom size, and whether you pay for utilities like electric, gas or trash. It also will tell you the affordability of that home.
