Partial rewire
Rewiring part of a house is common during remodels. The tie-in to old wiring is where the planning goes.

The short answer
A partial rewire replaces the wiring in one room, a kitchen, a bath or a floor, not the whole house. It suits remodels and phased projects. A licensed electrician replaces those circuits back to the panel, brings them up to current code, and makes sure no new work depends on old wiring that stays behind.
When partial makes sense
During a kitchen or bath remodel with open walls; when one area has damaged or altered wiring; or as phase one of a full rewire. If the whole house has knob-and-tube, partial work may not satisfy an insurer.
Code updates triggered
New circuits bring current rules into play: AFCI and GFCI protection, tamper-resistant receptacles, kitchen counter circuits, and outlet spacing. The adopted code edition decides.
See AFCI and tamper-resistant receptacles.
What the job includes
Running new home runs to the panel, abandoning or removing old cable, new boxes and devices, and checking panel spaces. Old wiring that passes through the room to other areas is traced and dealt with.
Permit, time and what changes the price
Permits and rough-in and final inspections apply.
Price drivers: room size, open vs closed walls, distance to the panel, panel spaces, devices. No price ranges are published here until we hold enough sourced, dated quotes; see cost guides.
Plan the whole house
Even if you rewire one room now, ask for a whole-house plan so later phases fit. Check the license on your state board before anyone starts: how to check an electrician license.
How the tie-in works
The cleanest partial rewire runs every new circuit straight back to the panel. Splicing new cable onto old cable inside the room keeps the weak link in place and is avoided where possible.
Old circuits that fed the room are disconnected at the panel and marked abandoned, or removed where walls are open. If an old cable also feeds a room outside the scope, the electrician either reroutes that load or tells you in writing that the old run remains.
Kitchens are a common partial rewire because current code calls for at least two 20-amp countertop circuits, GFCI protection and dedicated appliance circuits. Bathrooms need their own 20-amp receptacle circuit.

Primary-source research and fact checking
We read the model code, the federal safety notice, the municipal fee sheet or the utility tariff ourselves, and we publish the figure with the document it came from and the date we retrieved it.
Where a number cannot be traced to a primary source, we publish the shorter page and say what we could not verify. HyreElectrical does not perform, supervise or warrant electrical work. Authorship is organizational: this desk, not a named persona.

How this desk works
- Primary sources only. Code statements come from NFPA 70 as the model code. Safety statements come from CPSC. Permit fees come from the city or county fee sheet. Utility charges come from the filed tariff. We do not cite a blog that cites a source; we open the source.
- Our contractor store is five states, and 74% of it is Florida. Any figure built on that store is titled to those states and names the concentration in the first screen. It is not a national sample of electricians.
- Load calculations on this site are a published simplification in the shape of NEC 220.82 — first 10 kVA at 100%, remainder at 40%, HVAC at 100%, EVSE at 125%. They are labeled as not a stamped calculation. A licensed electrician using the adopted edition does that work.
- No national price for a panel upgrade is shipped. Labor rates, the adopted code edition, whether the utility is involved, and the state of the existing wiring move the invoice too far for a roundup to help. The cost pages publish named permit fees and the variables that move the price instead.
- We do not perform electrical work, and we take no payment for placement, ranking or a favorable mention. Nobody buys a position on this site.
Authorship on this site is organizational: the analysis belongs to the desk rather than to a named individual, and we do not publish credentials we do not hold. Our editorial policy sets out how we source, date and correct what we publish.
Sources & retrieval dates
HyreElectrical is a publisher. It does not perform, supervise, inspect or warrant electrical work, holds no electrical license, and matching is still being built, so an inquiry is not a service call.
This page is general information, not a diagnosis or a quote. Code rules vary by the NEC edition your state or city adopted and its local amendments.
