Community Development



When submitting for permits, please have everything ready prior to arriving - completed application, plans stapled in sets, and deposit (see below for 2022 deposit amounts.) Checks should be made payable to "City of Blue Ash". If payment is not included with submittal, we will call for credit card information (Visa or MasterCard only.) Submittals cannot be processed without a deposit. The submittal should be put in an envelope or rubber banded together and dropped off in the Community Development on top of black cabinet marked "Drop-Off Area".  For your convenience, there are envelopes in the lobby. If you have questions prior to submitting, please call our office at 513-745-8520.  Staff is available by appointment only; however, the Community Development lobby is open for dropping off and picking up during normal office hours, which are Monday-Friday, 8:00 AM-4:30 PM.  If you need to speak to someone regarding plan review, scheduling an inspection or Code questions, please call 513-745-8522.

Trying to determine if you need a permit?  Visit "Do I Need a Permit?", read the information below,  or call the Community Development Office at 513-745-8520.


A Permit is required prior to any regulated construction to ensure compliance with current Code. The City of Blue Ash adopts OBC, the Ohio Building Code, by reference for all commercial construction. A Building Permit application automatically includes review of other applicable Blue Ash Codes, including zoning and fire safety. All non-residential plans must be sealed by an Ohio Registered Design Professional; any plans submitted without a seal will be rejected without being reviewed. "Do I Need a Permit?" describes types of work that require Building and Zoning Permits. If your project involves potential fire or chemical hazards, you should also contact the Blue Ash Fire Department at 513-745-8533 to inquire about additional permit requirements.

Site Work Permits

A Site Work Permit is required prior to undertaking site clearing, cut and fill, or grading on a site, whether or not it is in preparation for construction. Generally, all non-residential projects and all multifamily residential projects will require the approval of the City Engineer. If a site work review is required for small projects that are submitted for a Building Permit, then a separate Site Work Permit may not be required; please call in advance to determine the requirements for your project.

Zoning Approvals

All permit applications that are submitted to the City of Blue Ash will be reviewed for compliance with Zoning Code regulations. Most approvals are administrative; however, all new non-residential buildings, large additions, changes to developments that were originally approved by a Board, Commission, or Council, construction that does not meet the Zoning Code requirements, and developments in the Downtown district are subject to other approval procedures. Please review the details if your project falls into one of these categories.
