Inspections and closing out your permit
In Franklin County, plumbing inspections are timed to whatever is about to hide the pipe: underground and under-slab piping is checked before concrete covers it, rough-in piping is pressure or water tested before walls close up, and a final inspection checks every fixture and backflow protection once the work is complete.
- In Franklin County: piping and equipment placed under a slab or floor must be in place and inspected before any concrete is poured or floor sheathing is installed over it (IRC R109.1.1.1).
- In Franklin County: rough plumbing, along with the mechanical, gas, and electrical rough-in, must be inspected prior to covering or concealment and before fixtures or appliances are set (IRC R109.1.2).
- In Franklin County: rough drain, waste, and vent (DWV) piping is tested with water, air, or (for plastic piping) a vacuum, and must show no evidence of leakage before it is closed in (IRC P2503.5.1).
- In Franklin County: the water-distribution piping is tested and must hold tight under the system's working pressure, or under a 50 psi air test for non-plastic piping, before it is concealed (IRC P2503.7).
- In Franklin County: the framing inspection cannot proceed until the plumbing rough inspection, along with the mechanical and electrical rough inspections, has been approved (IRC R109.1.4).
- In Franklin County: at the final drainage test, each fixture is filled and then drained, and its traps and fixture connections must prove watertight by visual inspection (IRC P2503.5.2).

- Can a homeowner pull a plumbing permit themselves in Franklin County?
- Under Ohio law (OAC 4101:8-1-01 Section 105.1; R.C. 3791.04(A)(1)(b); R.C. 4740.01(F)): Ohio has no statewide general contractor license, so the Residential Code of Ohio names the property owner directly as an authorized permit applicant: an owner or authorized agent who intends to construct, alter, repair, or change the occupancy of a residential building must first make application to the local certified building department and obtain approval, meaning a homeowner may pull their own permit and act as their own contractor. R.C. Chapter 4740's statewide licenses for electrical, HVAC, plumbing, refrigeration and hydronics contractors apply to 'construction projects', which R.C. 4740.01(F) defines to exclude residential buildings as defined in R.C. 3781.06, so that licensing does not reach one-, two-, or three-family home construction. In a county, township, or municipality with no residential building department certified by the state Board of Building Standards, R.C. 3791.04(A)(1)(b) and the Residential Code of Ohio's administrative rule both say the owner is not required to submit construction documents, seek approval, request inspections, or obtain a certificate of occupancy at all, which removes the state permitting framework, and with it the owner-builder question, in those jurisdictions. Confirm how Franklin County applies this before you apply.
