Weekly digest #152: inspector trends

What inspectors are flagging this quarter

Talked to twelve inspectors across six jurisdictions over the past month. The pattern is clear: inspections are getting tighter on the same handful of items. Not new code, just stricter enforcement of what was already there.

The shift seems driven by two things. First, jurisdictions are catching up on 2023 NEC adoption, and inspectors are no longer giving courtesy passes on items that were "new" two cycles ago. Second, insurance carriers are pushing back on claims tied to sloppy installs, and AHJs are feeling that pressure.

Here is what is showing up on correction notices most often right now:

• GFCI protection in finished basements per NEC 210.8(A)(5), including receptacles behind appliances
• Tamper-resistant receptacles missed in dwelling unit additions, NEC 406.12
• Working space violations at panels, NEC 110.26(A), particularly the 30-inch width
• Bonding jumpers missing on metal water piping near the service, NEC 250.104(A)
• EV charger circuits without proper load calculations under NEC 220.57

GFCI scope keeps expanding, and inspectors know it

The 2023 cycle pulled GFCI requirements into territory a lot of guys still install the old way. Dishwashers under NEC 422.5(A)(7), basement receptacles regardless of finish status, and outdoor outlets serving HVAC equipment under 210.8(F) are the three biggest miss zones we are seeing.

Heat pump installs are a particular sore spot. The 2023 code wants GFCI on the disconnect, and a lot of HVAC subs are still spec'ing standard non-GFCI disconnects. If you are the EC of record, you are the one eating the correction.

Field tip: when you walk a job before rough, photograph every appliance nameplate and disconnect location. If the inspector flags something six weeks later, you have proof of what was installed and when. Saves arguments and saves callbacks.

Working space, the silent killer

NEC 110.26 violations are climbing fast. The clear working space rules have not changed, but inspectors are pulling tape measures more often. The three numbers to keep burned into memory: 36 inches deep, 30 inches wide, 6.5 feet high. The 30-inch width does not have to be centered on the equipment, but it has to exist somewhere in front of it.

Common gotchas we are hearing about:

1. Panels installed in finished closets where the door swing eats the working space
2. Water heaters or shelving creeping into the depth dimension after the rough-in passed
3. Sub-panels in laundry rooms where the washer ends up directly in front
4. Garage panels with toolboxes or freezers parked in the zone

The fix is documentation. Note working space dimensions on your panel schedule, photograph the clear space at final, and if a homeowner moves a freezer in front of the panel later, that is on them, not you.

Bonding and grounding are getting a closer look

Three inspectors in three different states told me the same thing this month: they are spending more time at the service. Specifically, they are checking metal water pipe bonding under NEC 250.104(A)(1), intersystem bonding termination per 250.94, and the size of the grounding electrode conductor against 250.66.

The intersystem bonding termination is the one catching newer techs off guard. If the service was installed before 2008, it likely does not have one, and adding service equipment or a meter swap can trigger the requirement. Check before you quote.

Water pipe bonds also need a closer look on remodels. If a plumber dropped in a section of PEX between the meter and the bond point, the bond is now isolated and useless. NEC 250.104(A)(1) wants that connection within 5 feet of where the pipe enters the building. Walk the line before you sign off.

EV chargers, load calcs, and the EVSE conversation

Every inspector mentioned EV charger installs. The two recurring issues: undersized service for the added load, and missing or wrong load calculations in the permit package.

NEC 625.42 and the 2023 rules around energy management systems give you flexibility, but only if you actually use an EMS. A lot of installs are claiming EMS allowances on paper and then installing a dumb 50-amp circuit. That fails fast when the inspector asks to see the EMS device.

Field tip: if the panel is already at 80 percent calculated load, do not assume you can squeeze in a Level 2 charger without a service upgrade or a load management device. Run the numbers per NEC 220.83 or 220.87 before you sell the job.

Also worth noting: GFCI on the EVSE branch circuit per 210.8(F) is not optional just because the unit has internal GFCI. Inspectors are reading this strictly. If the disconnect or receptacle is outdoors, the upstream protection needs to be in place.

What this means for next week

Three things to do before your next rough or final:

• Pull your last three correction notices and sort them by article. Whatever shows up twice is your weak spot, fix the pattern, not the symptom
• Update your standard panel schedule template to include working space confirmation and intersystem bonding notes
• If you do residential, add a one-page EV readiness checklist to your sales process so the load calc happens before the contract, not after

Inspectors are not getting harder for the sake of it. They are catching up, and the techs who stay ahead of the trend are the ones who treat code references as a daily tool, not a once-a-cycle refresh.
