County staff propose separating permits, discuss code updates and EV wiring issues
Summary
Committee and staff discussed consolidating trade chapters, whether to split permits for phased work, possible fee-schedule changes, and contractor confusion under evolving state electrical and energy codes including EV charger wiring concerns.
Caroline County staff and committee members discussed a planned revamp of local building rules and options to reduce confusion when projects are phased or multiple contractors work under a single building permit. Staff (S5/Crystal) said the office is combining electrical, plumbing and building-code chapters into a single 'construction trades' chapter that will add an HVAC component and shift some content from licensing to permit requirements.
Committee members debated whether to require separate permits when a project is built in phases. "My thought is we separate out those permits," S5 said, arguing it keeps inspection records clear, while others warned splitting permits can increase inspection trips and fees and impose burdens on contractors. Staff suggested the issue could be addressed in next year’s permit-fee schedule by considering a 'sub-permit' model so related work can be charged proportionally by square footage with existing minimums (S5 cited a $50 minimum fee).
Members also reviewed state electrical-code timing. Chair (S1) said Caroline County is still operating under the 2017 electrical code and that the state has not adopted 2020; members discussed whether the state will skip to the 2023 code and noted many contractors are still adjusting to new energy requirements (insulation R-values, prescriptive vs. performance compliance).
On technical issues, participants described common EV charger installations—contractors often add a 60-amp subpanel in garages because a 40-amp feeder is insufficient—and noted nuisance trips on GFCI-protected receptacles. Staff and members referenced recent UL testing changes that require manufacturers to verify equipment compatibility with ground-fault protection, which may reduce callbacks.
The committee did not adopt policy changes at the meeting but asked staff to return with proposed options for handling contractor changes, permit-separation guidance, and possible fee adjustments for future consideration.
