We follow Kentucky's code, licensing and permit route instead. ### A two-family on one lot Two households, two meters and a set of shared lights. We trace the units together, then rewire them one at a time. ### A winter deadline An insurer or a lender sets a date that lands in the cold months. We keep heating circuits in service while we replace the others. ### Ceilings left on old circuits An earlier update reached the outlets but not the ceiling lights and switches, which still run on the original two-wire circuits. ## Old wiring in your Covington house? Maybe it showed up in an inspection report, or an insurer set a date that lands in January. At [Conflux Cincinnati Knob and Tube](https://confluxcincinnatiknobandtube.com/) we handle knob and tube replacement in Covington, KY, and in Ludlow, with permits and inspections run on the Kentucky side. Covington faces downtown Cincinnati across the Ohio River, and that short crossing changes the state, the code timetable and the licensing. None of the Ohio rules that govern a Cincinnati job carry over, so we plan to Kentucky’s. | Question | In Covington | | --- | --- | | Building permits | Planning and Development Services (PDS) of Kenton County | | Electrical inspection | Inspection Bureau, Inc., whose Northern Kentucky territory includes every area PDS serves | | Electrical code | 2023 NEC, enforced in Kentucky from January 1, 2025, with dated exceptions for one- and two-family homes | | Contractor licensing | Kentucky electrical licensing | | Utility for service work | Confirmed per address | | Historic district review | Confirmed per address | Kentucky’s Department of Housing, Buildings and Construction keeps a contact sheet for each county. For Kenton County, building inspection runs through PDS, and for the electrical inspector it says to contact the county or city office where the work is to be done. ## Which code does your rewire follow? The 2023 NEC, with a Kentucky timetable. Kentucky made it mandatory from January 1, 2025, but not all at once. For one- and two-family dwellings, three sections were held back until July 15, 2026, and the 2017 NEC applied to them until then. The delayed sections cover practical parts of a rewire: - **210.52(C):** receptacle outlets at countertops and work surfaces, which matters when a kitchen is rewired. - **230.67:** surge protection for dwelling services, which matters when a panel or service is replaced. - **314.27(C):** boxes at ceiling fan locations, which matters when ceiling circuits are run new. Some GFCI items in 210.8 were delayed separately, pending a revision to UL 943, the GFCI product standard. We confirm their status when the permit is opened rather than assume it. The [primer on knob and tube](https://confluxcincinnatiknobandtube.com/guide/knob-and-tube-wiring/) explains why old two-wire circuits and modern protection requirements meet awkwardly. ## Is your house old enough to have it? Quite possibly. Census estimates put 9,268 of Covington’s 20,946 housing units, or 44.2%, in buildings from 1939 or earlier. Kenton County as a whole sits at 19.8%, so Covington’s older stock stands out within its own county. | Housing units | Covington | Ludlow | Kenton County | | --- | --- | --- | --- | | Built 1939 or earlier | 44.2% | 57.5% | 19.8% | | Built before 1950 | 52.5% | 63.4% | 24.9% | | Detached houses | 55.2% | 60.5% | 67.9% | | Two-unit buildings | 11.0% | 7.2% | 4.8% | U.S. Census Bureau ACS 5-year estimates, 2019-2023, for each city and the county. ### Own a two-family? At 11.0% of units, Covington’s two-unit share is more than double the county’s. We start a two-family rewire with the circuits the units share, such as stair, basement and porch lights, so we can then do each unit on its own schedule. [Two-family and rental rewiring](https://confluxcincinnatiknobandtube.com/two-family-and-rental-rewiring/) covers occupied buildings. ### Live in Ludlow? Ludlow, in the same county, has the older profile: 1,287 of its 2,240 units, or 57.5%, date from 1939 or earlier. It shares Covington’s permit route, through PDS of Kenton County with IBI inspecting the electrical work. ## How do the permit and inspections work? The electrical permit is opened under Kentucky’s process, and IBI carries out the inspections. IBI’s guidance says a permit is needed whenever wiring is installed or altered, and that it cannot approve work it cannot inspect. In practice, that sets the order of a Covington job: 1. **Trace first.** We follow every K&T circuit to its fuse or breaker, confirm it live or dead at both ends, and count openings per room. 2. **Rough-in.** We run new cable and set boxes one area at a time, keeping essentials such as a freezer or medical equipment powered. 3. **Inspection.** IBI sees the rough-in while everything is exposed. 4. **Close and finish.** Openings are patched from the written list, devices go in, and IBI returns for the final. The walkthrough of [how replacement works](https://confluxcincinnatiknobandtube.com/guide/how-knob-and-tube-replacement-works/) adds detail, and a [knob and tube inspection](https://confluxcincinnatiknobandtube.com/knob-and-tube-inspection/) is the usual first booking. New cable and a new box left exposed in an opened wall, waiting for the rough-in inspection before any patching. ## New outlets, but the ceiling lights are still old? That happens when an earlier update reached the outlets but not the ceilings. We trace those lights and switches like any other circuit, from the fuse or breaker to the last fixture. In plastered rooms, we usually run new cable through stud bays and ceiling joists with small openings at the top and bottom of each run. On the first visit we count the likely openings room by room, and that count becomes the patching list after inspection. [Plaster-wall rewiring](https://confluxcincinnatiknobandtube.com/plaster-wall-rewiring/) explains the routes. ### Can you do part of the house first? A Covington owner facing a deadline can start with the circuits that matter most and leave the rest for later. The scope letter then names what was replaced, what was disconnected and what is still on K&T. [Partial replacement](https://confluxcincinnatiknobandtube.com/partial-knob-and-tube-replacement/) covers how that boundary is recorded. ## What will your insurer or lender want to see? Records, not a phone call. Requests about knob and tube often arrive in writing, from an insurer after a policy review or a lender during a purchase. We answer with a set of records. - **Scope letter:** which circuits were replaced, disconnected or left, in plain terms. - **Circuit map and panel directory:** what each breaker now feeds. - **Disconnection record:** retired runs, capped at both ends, with photos. - **Permit final:** proof that IBI inspected the work. [K&T replacement for insurance](https://confluxcincinnatiknobandtube.com/knob-and-tube-insurance-replacement/) covers carrier deadlines, and the guide to [paperwork for insurers](https://confluxcincinnatiknobandtube.com/guide/knob-and-tube-paperwork-for-insurers/) explains what each document answers. ## Rewiring in winter? The region’s official weather normals are recorded at the Cincinnati airport, which sits in Hebron, Kentucky. It averages about 99.8 days a year with a low at or below freezing, and a January mean low of 23.1°F. If you live in the house through a winter rewire, we keep its heating circuits in service, or switch them over within the day. We sequence rooms so the furnace and any space heating are never the circuits waiting overnight. ## What will it cost? Conflux’s typical range is $12,000 to $35,000 and up for a whole house and $2,000 to $10,000 for a partial job. On IBI’s schedule, added wiring in a single-family house totals $120 with processing, and $125 in a two-family. We confirm whether a Kentucky permit carries exactly those lines when the permit is opened. The rest of your price depends on the house: live circuits, floors, plaster and panel space.

IBI inspects electrical work in Covington. Its published schedule, effective January 1, 2025, totals $120 for added wiring in a single-family house and $125 in a two-family, and a reinspection trip is $40. We confirm whether a Kentucky permit carries exactly those lines when the permit is opened. Our ranges are the same as in Ohio: Conflux typically charges $12,000 to $35,000 and up for a whole house and $2,000 to $10,000 for a partial replacement. The written estimate from the circuit list sets the final price. ### Can an electrician licensed only in Ohio rewire a house in Covington? No. Kentucky runs its own electrical licensing, so an Ohio license or a Cincinnati registration is not the credential to ask about here. Ask for the Kentucky license number and check it. Our Terms page explains how we arrange work on the Kentucky side. ### Which code edition does a Covington rewire follow? Kentucky began mandatory enforcement of the 2023 NEC on January 1, 2025. For one- and two-family dwellings, three sections, 210.52(C), 230.67 and 314.27(C), were not mandatory until July 15, 2026, and some GFCI items in 210.8 were delayed pending a revision to UL 943. We confirm the current status with the permit. ### Who inspects electrical work in Covington? Inspection Bureau, Inc. Its Northern Kentucky territory covers every area served by Planning and Development Services of Kenton County, which includes Covington, Ludlow and Fort Wright. Building permits, where the job needs one, come from PDS. ### Does Ludlow follow the same permit route as Covington? Yes. Ludlow is also served by Planning and Development Services of Kenton County, and IBI's Northern Kentucky territory includes it. Its housing is older than Covington's: 57.5% of Ludlow units date from 1939 or earlier, against 44.2% in Covington. ## Nearby service areas - [City of Newport building official; electrical inspector confirmed per address**Newport, KY** 45.8% of homes built in 1939 or earlier](https://confluxcincinnatiknobandtube.com/service-areas/newport-ky/) - [City of Cincinnati; electrical by IBI**Over-the-Rhine** 72.9% of homes built in 1939 or earlier](https://confluxcincinnatiknobandtube.com/service-areas/over-the-rhine/) - [City of Cincinnati; electrical by IBI**Mount Auburn** 50.8% of homes built in 1939 or earlier](https://confluxcincinnatiknobandtube.com/service-areas/mount-auburn/) ## Guides for houses in Covington - [Learn**What is knob and tube wiring?** How the original wiring in your older house works, what it did well, where it falls short, and what to do about it.](https://confluxcincinnatiknobandtube.com/guide/knob-and-tube-wiring/) - [Learn**How is knob and tube replaced?** What happens between our first visit and your final inspection, and why each step depends on the one before it.](https://confluxcincinnatiknobandtube.com/guide/how-knob-and-tube-replacement-works/) - [Decision Guide**How do you compare knob and tube rewiring quotes?** Two honest quotes can be far apart because they price different jobs.
