State License
STATE OCILBRequired for all
Plumbing contractors operating in Cincinnati, Ohio, must navigate a two-tier regulatory environment. First, you must hold a valid state-level plumbing contractor license issued by the Ohio Construction Industry Licensing Board (OCILB). This state license serves as the foundation for your professional practice across Ohio.
Second, you must register your state license with the City of Cincinnati Department of Buildings and Inspections. This local registration is mandatory to pull permits and perform work within city limits. Always ensure your insurance is current and that every project is properly permitted to avoid stop-work orders and fines.
Always verify if your project falls under Hamilton County Public Health jurisdiction (e.g., septic systems) vs. City of Cincinnati B&I (e.g., municipal plumbing).
