Building Inspection


UPDATE: 3-23-2020

The Building Inspection Division is implementing procedural changes in response to the coronavirus pandemic by reducing person-to-person contact. It is our intent to continue our services and to minimize the inconvenience to applicants and customers. The information in this space will be updated periodically.

Applications and Plan Intake – Mail or ship all building, plumbing, gas, electrical, HVAC, fire alarm, fire suppression, water, and sewer permit applications, plans, and revisions to our physical address:

City of Dayton Building Inspection

371 W. Second St, 2nd floor

Dayton, OH 45402

Mechanical permits (plumbing, gas, electrical, HVAC, sewer, and water) can continue to be faxed as always to this office (937-333-4284) or mailed. Fees will be processed as explained below.

• Distribution of Approved Plans & Permits – We are developing procedures to minimize any inconvenience for distribution of approved plans and permits while the public does not have access to our offices. At this time, our primary method will be to mail or ship the permits and plans. For anything that can fit into a 10” x 13” envelope, we will mail to the applicant. Arrangements will need to be made with Building Inspection staff for shipping larger items from this office and shipping costs will be the responsibility of the applicant. For the present, contact Stacy Sandberg, 937-333-3986 or for questions or clarifications.

• Fire Alarm and Sprinkler Permits – The Tuesday morning over-the-counter permitting for minor modifications of fire alarm and of sprinkler systems is suspended. All fire alarm and sprinkler permit applications and plans will be received, routed, and processed in the same manner as all other applications and plans.

• Meetings – For meetings that would typically be held in our offices, the Building Inspection Division is arranging for conference calling. Please coordinate these meetings with the City employee that is your primary contact.

• Payment of Fees – There is no change in the payment of fees; however, you will need to make payment by check or credit/debit card. Fees can still be paid by check made out to “City of Dayton” and sent along with the applications or mailed separately. Fees may also be paid by providing credit/debit card information over the phone. To get a determination of fees for a project, call either (937) 333-3986 or (937) 333-6794. Be prepared to provide the project value, as this will be the basis on which fees will be determined.

• Inspections – Inspections will continue with the following considerations:


o New work and alterations in unoccupied residential buildings may be inspected as long as sufficient social distances can be maintained.

o Inspections that require entry into an occupied residence will be limited.

o Where we have concerns about entering the property, we can meet the contractor at the property, but only the contractor will enter, and show us digital (photographic or video) evidence of compliance.

o Other inspection requests will be reviewed based on public health, safety, and availability of staff.


o New work and alterations in occupied commercial buildings may be inspected as long as sufficient social distances can be maintained.

o Third Party Inspections must be pre-approved by City of Dayton Building Division.

o All other inspections will be reviewed based on public health, safety and the availability of staff.


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.
