Building Inspection

Effective September 20, 2017, fees for building permits have changed per Ordinance No. 31585-17 passed by the Dayton City Commission on August 30, 2017. Fees for plan reviews did not change. Fees for permits for buildings, mechanical, electrical, and plumbing have increased. Permit applications for Building/Zoning, Mechanical, and Tent permits are now updated to reflect these changes.  Access permit applications by selecting "Building Permit Forms" just to the left of this note.  To find out what fee amounts may apply to your project, please call 937-333-3986 or 937-333-6794.

The 2019 Residential Code of Ohio for all 1, 2, and 3-family dwelling projects became effective July 1, 2019 and will apply to all applications for permits filed on and after that date.  The link to the RCO in "Building Codes" to the left of this paragraph provides access to both the 2013 and 2019 versions of the RCO.


The City of Dayton is providing waivers and refunds for fees associated with obtaining Building and Zoning permits from now until the end of the year for residential and commercial property repairs that are a result of the May 27, 2019 tornadoes.  Details for obtaining waivers and refunds for fees can be found at Tornado Relief Program.

An explanation of steps a residential property owner should consider in their recovery efforts can be found in the following brochure: NEXT STEPS AFTER STORM DAMAGE.
