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.

All permits must be submitted using our online system, which is accessible by using the link below . Once the review is completed, 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.
Most structures require a site plan approval from the Health Department prior to us releasing the permit.  Please contact their department, 815-544-2951, to obtain more information.  If your property is located within a subdivision, there may be additional approvals/permits required.  Please check with your association for more information.

Please note, if you're address is being rejected, it may not be located within our jurisdiction.
