Yakima County is pushing new rules that would keep them at least a block away from homes.
Strip clubs would also be limited to industrial zones.
Commissioners will hold another public hearing later this month when they could adopt the changes.
Yakima county says these requirements would make their decisions on permits easy.
"Now with the 400 feet we really have this easy yes or no. Does it meet the requirement? Does it not? And is it located far away enough from the protected use," said Nate Gwinn, Yakima County Senior Project Planner.
Yakima city council will hold a study session Wednesday on the same changes.
This comes in the middle of a six-month moratorium on new adult businesses.
