Welcome to Montgomery County, Ohio Building Regulations!


In response to the directive issued March 22, 2020 by the Ohio Department of Health, effective March 24, 2020 and continuing until further notice, Montgomery County Building Regulations will use the following temporary policy to deal with issues surrounding the new Coronavirus – COVID-19. Please note that this is a developing public health situation, and we are continuing to monitor the situation. We reserve the right to make changes to this policy as necessary to protect employees and public health. We will endeavor to conduct emergency inspections, such as building damage assessments and emergency utility reconnects as appropriate to protect first responders and those with urgent health needs. Please visit our website (www.mcohio.org/build) for additional updates.

Note that all inspections will be essentially hands-free, meaning the owner or owner’s representative must open doors, remove panel covers, operate all switches, breakers, valves, and test equipment as necessary to verify compliance.



  • New work and alterations in unoccupied residential buildings in order to make them habitable may be inspected as long as sufficient social distances can be maintained. Other alterations are considered non-essential and will not be inspected at this time.
  • Inspections that require entry into an occupied residence will be restricted to work necessary to keep the residence habitable. 
  • Where we have concerns about entering the property, we can meet the contractor at the property, but only the contractor enters, and shows us digital (photographic or video) evidence of compliance.
  • Other inspection requests will be reviewed based on public health and safety, availability of staff, and compliance with orders from the State of Ohio.


  • Inspections will continue for essential operations such as, but not limited to, grocery stores, drug stores, restaurants, office supply stores, and construction products stores, and other businesses deemed essential by the State.
  • Inspections will be suspended for non-essential retail trade until further notice.  Examples include clothing and accessory stores, beauty and nail salons, and tattoo parlors.
  • New work and alterations in occupied commercial buildings may be inspected as long as sufficient social distances can be maintained.
  • Third-Party Inspections must be pre-approved by Montgomery County Building Regulations.
  • All other inspections will be reviewed based on public health safety and the availability of limited staff.

We will continue provide updates to you as the situation continues to change.
