Do I need a plumbing permit in Columbus, Ohio? What is exempt, the $140 and $275 permits, and who can pull them

What needs a permit and what does not

Building and Zoning Services (BZS) puts the line at concealed pipe. Its FAQ (read 23 October 2026) lists as exempt "The repair of leaks in drains, water, soil, waste or vent pipe", then adds: "If any concealed trap, drain-pipe, water, soil, waste or vent pipe becomes defective" and must be replaced, "such work shall be considered as new work and an approval shall be obtained and inspection made." For the full exempt list BZS points to Ohio Building Code 102.10.

The two minor items are the only plumbing lines on the City's Approved Minor Work Permit List (rev. March 2019): "Backflow Preventer / Back Water Valve (New or Replacement)" and "Water Heater Replacement". Fees are from the 2026 Combined Development Related Fee Schedule: "Mechanical, Electrical, and Plumbing (includes 2 inspections)" $275, "Minor Work Permit - Electrical, Mechanical, or Plumbing only" $140, "Additional Inspection Trip" $225. Working without a permit adds a penalty of $200 at Level 1, up to $750, $1,750 and $4,000 at Level 4. The schedule has no per-fixture or water-heater line for houses; the flat fee covers the job.

The 2026 plumbing application offers three choices: "Minor Work Permit (per Approved Minor Work Permit List)", a "1 Inspection Permit (not available for 1,2,3 family structures)", and "Full Permit (includes two inspections)". Tick nothing and "a full permit will be issued". Anything not on the minor list and without plan approval needs "Trade supervisor approval".

Who can pull it

An Ohio-licensed, City-licensed plumbing contractor. OCILB licenses plumbing contractors; check the firm on OCILB eLicense. The application asks for a "City of Columbus Registration Number", and the City also licenses journeyperson plumbers ($150 a year on the 2026 schedule). In our file 68.1% of the 357 plumbing firms matched an active OCILB license by name; the rest are names we could not match, and 0 matched a lapsed record. Name checks for City licenses are in the Columbus contractor license lookup.

You, for your own work in your own house. The plumbing application lists "Property Owner" as a permit holder, and "a separate Homeowner's Building Permit Affidavit must also be completed." The BZS FAQ says owners of a single-family home they live in can get permits "for work they will be doing themselves", that "Property owners cannot purchase permits for work that they will hire a contractor to perform", and that non-family helpers are allowed only if "no payment should be given or implied".

How to apply and close it

1. Apply in Citizen Access or at BZS, 111 North Front Street ((614) 645-7433). "Payment is required at the time of submission."
2. Pick Minor Work Permit for a water heater or backflow device; otherwise it is a full permit.
3. Book inspections in Citizen Access or on (614) 645-8235. Next-business-day requests are taken "until midnight"; inspectors work 8 a.m. to 4 p.m.
4. Watch the trips. Each inspector visit uses a trip whatever the result, and BZS says "We do not refund trips or transfer them between permits." A failed water-heater inspection on a minor permit means buying a $225 trip.
5. Do not let it lapse. Once work starts, "the permit will expire in six months, unless inspections are performed." After the final inspection it closes on its own.

What 13,097 Columbus plumbing permits show

Columbus plumbing is concentrated: one firm holds 18.6% of the permits and five hold 37.5%. Finishing is the thing to check. A usual 111 days to final means the final often lands months after the plumber leaves, and among the 109 firms with 10+ permits the 10th-percentile firm reached final on 41.1% of its permits and the 90th on 92.7%; 31 were under 70%, some of them among the busiest. Ask who books the final before you pay the last invoice. Demand is flat through the year (index 90 to 107), so timing will not get you a cheaper plumber. Columbus plumbing permits carry no job value, so this file cannot price the work.

What this does not tell you

The minor work list is dated 2019, and the exempt list sits in Ohio Building Code 102.10, which BZS cites rather than reprints; BZS intake ((614) 645-7433, bzs-intake@columbus.gov) confirms which permit a job gets. Sewer and water line work outside the house is done by a separately licensed City "Sewer, Water, Sewer/Water Contractor", a $350 license that needs "Prior approval required from Public Utilities" (2026 fee schedule); ask BZS which permit that job takes. "Reached final" counts a permit as finished only when the City's record shows Final Inspection Approved or a certificate of occupancy, so a plumber who never calls for the final shows as open even if the work is sound.
