Welcome to Montgomery County, Ohio Building Regulations!
- The citizens and users of buildings in many of the jurisdictions in Montgomery County, including all of the townships and several of the cities and villages.
- Building codes for new construction, additions, alterations, and changes in the way buildings are used. We also enforce flood damage prevention regulations, and airport zoning around the Wright-Patterson Air Force Base.
We work with…
- Local zoning and fire departments
- Public Health – Dayton and Montgomery County
- Many other state and local agencies involved in specific aspects of building construction and use approval, such as daycare licensing, public swimming pools, elevators, boilers, etc.
- Building damage due to fire, vehicle impacts, wind, flood, etc.
- Work done on, or occupancy of, buildings without required approvals or inspections

Public Parking is available in the County Garage accessed off of Second Street.
In response to safe re-opening protocols for restaurants, night clubs, bars, and similar places of public assembly, we’ve established the following guidance:
- Seating is reduced to 50 percent of the approved occupant load.
- If the approved occupant load isn’t known:
- Check with fire or building departments to see if they have the approved maximum occupant load on file.
- If no Certificate of Occupancy is available, then either the fire department or the building department can assist in coming up with a temporary calculation using charts in OBC Chapter 10, and then dividing the resulting answer in half for the 50% capacity rule.
- If the approved occupant load isn’t known:
(Building department contacts in Montgomery County are in our web directory: http://www.selectmcohio.com/building/contact-us-and-partner-agencies )
- If seating re-arranged and/or temporary divider separations are installed:
- Dividers must not make exit paths narrower or more confusing to navigate.
- Dividers must be at least six-feet tall, but must also be least 24 inches down from the ceiling.
- Dividers must be of acceptable materials and not be permanently installed. Hanging plastic sheets or shower curtains may be questioned regarding fire safety if the quantity is too great or if the flamespread risk is too high.
- The amount of combustible decorative materials suspended from walls or ceilings is limited per the Ohio Building Code, Section 806.
- There is no limit on the amount of suspended non-combustible decorative materials as long as they do not obscure the exit path.
If fire departments can review and inspect these temporary modifications to existing approved facilities, no building permits will be required from Montgomery County. Otherwise, contact us for further guidance. More elaborate or unusual modifications may require new building permits.
Anyone needing permits for rebuilding projects from the tornadoes is welcome to apply to the Building Regulations office before the May 31 deadline to take advantage of these waivers. On June 1st permit applications will not be processed without the payment of the appropriate fees per the current fee schedule.

We have started a prototype program for submitting one-, two- or three-family residential projects electronically. This program allows you to submit drawings and plan changes via email. Every submittal must be a flattened PDF (no layers) and must be accompanied by a completed Residential Application Form or a Supplemental Document Submittal form. The email address is firstname.lastname@example.org.
Fee payments can be made by mailing a check or using our electronic Online Payment portal, but for new submittals, you will need to wait until our Permit Clerk has validated the submittal and assigned it a “Case Number” (once the project is approved, that will be referred to as a Permit Number).
You are welcome to call our office for more information.
