Replacing your panel? Surge protection is now part of the job

What changed

Pennsylvania's Uniform Construction Code moved to the 2021 I-Code series and the 2020 National Electrical Code with effect from 1 January 2026. The electrical half of that is the part with the immediate, concrete consequence for homeowners.

The 2020 NEC introduced Article 230.67, which requires that all services supplying dwelling units be provided with a surge-protective device. Previous code cycles treated surge protection as a good idea. This one treats it as part of the service.

The clause that catches people

It would be easy to read that as applying only to new construction. It does not. Section 230.67(D) states that where service equipment is replaced, all of the requirements apply.

So a 1970s panel swapped for a modern one in an otherwise untouched house falls inside the rule. In practice, in Bucks and Montgomery County, that means most panel work now carries a surge-protective device whether or not anybody asked for one.

What it means for the price

It adds a line to the quote. The device itself is a modest part of a panel job, and it installs at the same time by the same person, which is the cheapest moment it will ever be fitted. The alternative — having one added later as its own visit — costs more for the same result.

What is worth watching is quote comparison. An estimate written before the code changed, or by somebody who has not caught up, will be missing this and will therefore look cheaper than one that includes it. That is not a better price. It is a different scope, and the inspector decides which one is correct.

The other 2026 changes worth knowing

Surge protection is the one with the widest reach, but the same code adoption brought several other residential changes:

• A 36-inch clear path is now required from emergency escape and rescue openings.

• Deck design provisions were revised.

• New vapor retarder and continuous insulation provisions apply to the building envelope.

Accessibility requirements did not move with the rest. Those remain at the 2018 IBC Chapter 11 standard following a court stay issued in October 2022.

How to check what applies to your house

The code is statewide, but it is enforced by your township or borough rather than by the county, and municipalities that adopted the code before 1999 may carry local amendments that exceed the state baseline. The state holds no central record of those, so the only reliable answer comes from the office that will inspect the work.

One more local quirk: who inspects the electrical work varies by township. Newtown Township brought inspections in-house on 1 January 2023; before that the homeowner hired a third-party underwriter directly. Doylestown Township publishes its own approved list. Ask which arrangement applies before anybody schedules anything.
