About each permit

Commercial Building, Electrical, HVAC and Fire-Protection Permits

New construction, a tenant build-out or a remodel of a commercial building permitted by the Warren County Building & Zoning Department is priced on the county's 'BUILDING FEES - COMMERCIAL' schedule, linked from the department's Building and Zoning Fees page, whose heading reads 'PLUS 3% STATE SURCHARGE'. Which jurisdictions this covers is set out on the county's contact sheet, which states that 'Building & Zoning permits must be obtained from the following CITIES: Blanchester/Clarksville, City of Mason, Village of Harveysburg, City of Middletown, City of Franklin, City of Monroe, City of Loveland, City of Springboro, Village of Carlisle'. The department's pages list Clinton County, the City of Wilmington and the City of Franklin under 'Provided services to other Counties/Cities' and state that 'The Warren County Building Department reviews plans and performs inspections for the above jurisdictions ONLY. All building permits are to be applied for through those jurisdictions.' The county's September 2026 permit report lists county-issued permits in the 'Village of South Lebanon'. The department's home page states that 'All commercial projects in Hamilton Township need to be submitted to Hamilton Township for zoning and fire review PRIOR to being submitted to Warren County for building permit review.' The FAQ states that drawings are needed for sprinkler systems, fire alarms and hoods, and answers 'Do I have to be registered as a general contractor?' with 'No.'

County Zoning Permit (Franklin, Harlan, Turtlecreek, Union and Washington Townships)

A business building, expanding or changing a site in the five townships where the county administers zoning needs a county zoning permit. The Zoning Department page states 'our office only does Zoning for the following: Franklin, Harlan, Turtlecreek, Union, and Washington Townships,' and the county contact sheet states that 'The Warren County Zoning Office has jurisdiction in the following townships: Franklin, Harlan, Turtle Creek, Union and Washington.' The same contact sheet lists Clearcreek, Deerfield, Hamilton, Massie, Salem and Wayne Townships as 'not under the Warren County jurisdiction' and names the villages and cities from which zoning permits must be obtained, so a business there applies to that township or municipality instead. The figures are from the county Zoning Fees schedule linked as 'View our Fees' on the Zoning Department page, whose footer reads 'Revised for Comm. Meeting 3-16-10 Res. 10-0379, 7-14-15 Res. 15-1106 Res. 17-1170, Res. 22-0931.' The Zoning Office is at 406 Justice Drive, Lebanon, 513-695-1294.
