Building & Zoning

As the Building Department for unincorporated Boone County, we are committed to the quality of construction within our jurisdiction. The following information (also available as a handout) has been created in order to assist in a more efficient permitting and construction process by offering information and guidelines, as well as common mistakes our department encounters. We ask that you please refer to these handouts, as the information contained herein can potentially be time and cost effective for all parties.

An appointment is not required for a building permit. Information for a building permit may be dropped off, mailed, or faxed to our department at any time. Once the review is complete the applicant will be notified whether it complied. Please note that any missing information can result in the delay of your processing. A building permit will be released once the review is approved and payment has been received.

This information outlines many, but not all, of Boone County codes. It is important to note that ALL building and zoning codes must be in compliance.
