How long does it take to legalize a basement ADU in Kennesaw?

Timelines for legalizing a basement unit in Kennesaw depend on the scope of work needed to meet code, such as adding a proper egress window, meeting ceiling height requirements and separating utilities, plus however long the city or Cobb County building department takes to review permits. There is no fixed timeline this site can publish, since both the construction scope and permit review times vary case by case. Contact the Kennesaw or Cobb County building department directly for current review timelines.
