Newport, KY and its Campbell County neighbors: knob and tube replacement city by city

Old wiring in a Newport house or two-family?

An inspection report, an insurer’s letter, or a two-family where one unit’s fuse kills the porch light. At Conflux Cincinnati Knob and Tube we handle knob and tube replacement in Newport, KY, and next door in Bellevue, Dayton and Fort Thomas.

Each of those cities routes permits a little differently. Newport keeps a building official of its own, so before we price your job, we confirm which office covers the address.

Which office handles your permit?

It depends on the city. The state’s contact sheet lists Newport’s building official apart from the other Campbell County cities, and IBI inspects electrical work in the other three.

The table comes from two public sources: the county contact sheet from Kentucky’s state housing and buildings department, and IBI’s notice to contractors listing its Northern Kentucky territory.

Who inspects electrical work in Newport?

We confirm it for each address. For electrical inspection, the state’s contact sheet gives no single name. It tells contractors to ask the county judge-executive’s office or the office of the city in which the job sits.

So we never skip one step. Before we price or schedule a Newport job, we confirm with the city which inspector covers the address and how the permit is opened. Fees follow the same rule: that office sets them, and we confirm them for your address.

Is your house old enough to have it?

Quite possibly. Census estimates put 3,614 of Newport’s 7,883 housing units, or 45.8%, in buildings from 1939 or earlier. Its two-unit share, 13.5%, is about three times Campbell County’s 4.3%.

Figures are Census Bureau American Community Survey five-year estimates covering 2019 through 2023, for the four cities and Campbell County.

Own a two-family?

In a Newport two-family, we find the shared circuits before we open either unit. Lights in the hallway, on the stairs, in the basement or at the porch can be fed from one unit’s fuses or an old house circuit, and we move them so each panel serves only its own unit.

With both households at home, each keeps a circuit live for essentials such as a freezer, a home office or medical equipment, and heating stays on through cold spells. Two-family and rental rewiring sets out the order of work, and preparing for a rewire helps residents plan the days without power in certain rooms.

Live in Bellevue, Dayton or Fort Thomas?

We work there too. The three neighbors share an electrical inspector, IBI, but not a housing profile. Bellevue is the oldest, Fort Thomas the youngest, and Dayton sits between them.

Bellevue

Bellevue has the oldest stock of the four: 1,919 of its 2,915 units, or 65.8%, date from 1939 or earlier, and more than three-quarters predate 1950. Where original circuits survive, they may run through attics and ceilings that later work never reached. K&T and attic insulation covers clearing an attic before an energy upgrade.

Dayton

In Dayton, 1,362 of 2,699 units, or 50.5%, date from 1939 or earlier, and 68.1% are detached houses. Building permits come from the Campbell County Building Department, and IBI inspects the electrical work, so the path is set before the first visit.

Fort Thomas

Fort Thomas is younger, with 30.6% of units from 1939 or earlier and two-thirds detached houses. A house with breakers and three-prong outlets there can still carry a few original circuits, which is why we confirm each run instead of assuming. The guide to active and abandoned K&T explains how.

Which code applies on this side of the river?

Kentucky’s, not Ohio’s. Every one of these cities follows Kentucky’s adoption of the NEC. Enforcement of the 2023 edition began January 1, 2025, with three sections for one- and two-family homes deferred to July 15, 2026.

Those sections cover countertop receptacles, surge protection for services and ceiling fan boxes, all of which can come up in a rewire. The Covington page sets out the timetable in more detail, including GFCI items delayed pending a product-standard revision.

Buying a house on the Kentucky side?

A buyer coming from Ohio may expect Cincinnati’s permit office and fee schedule. In Campbell County, the route depends on the city, and the papers a lender or insurer asks for have to come from the office that inspected the work.

Within an inspection period, three things are worth getting in writing:

• The circuit list. Which circuits are live K&T, which are dead, and which were spliced into newer cable.
• The scope and sequence. What has to be replaced before closing or before the insurer’s date, and what can wait.
• The permit route. Which office will issue and inspect the permit for that address.

K&T before closing is about timing during a purchase, and the guide to knob and tube and mortgages explains what lenders tend to ask for.

Will we have to open your plaster?

A little, in planned spots. Original plaster sets the routes, and where a wall is framed with lath behind the plaster, we fish new cable through a stud bay with a small opening at each end.

We write down each room’s likely openings on the first visit. Patching waits for the rough-in inspection and then works through that record, so nothing the inspector still needs is hidden. Plaster-wall rewiring shows how we choose routes.

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. In Bellevue, Dayton and Fort Thomas, IBI’s schedule totals $120 for added wiring in a single-family house; Newport’s office sets its own fee.

We check at application whether a Kentucky permit uses the same lines. Beyond the permit, your price follows the building: live circuits, units, stories, walls and panel. An inspection of the K&T produces that list, whole-house rewiring covers doing everything at once, and what knob and tube is gives the background.
