Ohio, Hamilton County Plumbing Permit Regulations and County Ordinances for Unincorporated Areas
Hamilton County, Ohio Plumbing Permit Requirements
In Hamilton County, Ohio, plumbing permits and inspections are handled by the Hamilton County Public Health District for all areas except the cities of Cincinnati, Norwood, Springdale, and Sharonville. For properties in unincorporated areas, the Division of Buildings + Inspections is responsible for issuing building permits. A zoning certificate from the local zoning authority is a prerequisite for submitting a building permit application in these areas.
- Jurisdiction: Hamilton County Public Health District manages plumbing permits and inspections county-wide, excluding specific cities. The Division of Buildings + Inspections handles building permits for unincorporated areas.
- Unincorporated Areas: Properties in unincorporated areas of Hamilton County require building permits from the Division of Buildings + Inspections. Obtaining a zoning certificate from the local zoning authority is necessary before applying for a building permit.
- Contractor Requirements: Plumbing contractors must possess an Ohio Contractor Industry Licensing Board (OCILB) state license and be bonded and registered with Hamilton County Public Health. A $10,000 performance bond is required for all contractors installing plumbing.
- Permit Application: Applications typically require a completed permit application form, site plans, construction drawings (sealed when required by law), contractor licenses, and an estimated construction cost. For residential work in one- to three-family dwellings, a piping schematic of the waste and vent system is needed, but a professional engineer or architect's seal is not.
- Inspections: A series of inspections are required as work progresses, including lower rough (underground piping) and upper rough (piping before drywall). Specific testing requirements for piping must be met. Contractors must call to schedule same-day inspections between 7:30-9:00 a.m.
- New Construction: For new buildings, a permit number from the Metropolitan Sewer District (MSD) or a Sewage Disposal permit is required before the upper rough plumbing inspection.
