Caroline County board backs adopting 2021 mechanical code, proposes inspections and local registration

Caroline County’s Construction Trades Board voted to move forward with a package of code changes designed to tighten oversight of HVAC and electrical work in the county and to ask the county commissioners to consider the changes at a workshop in early December. Board members recommended adopting the chapter 1 (scope and administration) portions of the 2021 International Mechanical Code and agreed inspections should be required for new construction, most unit replacements, and full-home HVAC installs.

The board chair summarized earlier staff workshops and told members the board should present a clear list of what it wants the commissioners to approve. “Motion carries. Go for it all,” the chair said after board members moved and seconded a recommendation to present the full package to the commissioners. Levi, a contractor who reviewed the draft code, said, “As far as the code goes, I didn’t see anything in there that really stuck out to me that was…tremendously terrible.”

Why it matters: members said local registration and inspection authority would help the county address unlicensed or marginal work that can cause safety and durability problems — for example, unsafe wiring, improper condensate handling on mini-splits, or systems left improperly connected. The chair noted the state passed a law limiting some equipment sales to licensed contractors, but said county-scale enforcement can be difficult because residents can buy equipment out of state.

Key details adopted by the board for the recommendation include: inspections for new construction and most replacement installations (a common practical threshold discussed was replacement of more than roughly 50% of ductwork or full-system replacements), requiring Manual J load calculations for new full-house systems, and permitting/inspection requirements for full-home mini-split installations. For simple repairs and minor ductwork fixes, the board generally recommended exemptions to avoid overburdening homeowners and contractors.

Contractors raised several practical issues the draft must address. Multiple participants objected to the IMC’s refrigerant service locking caps requirement on grounds of cost and logistics (participants placed the accessory cost at roughly $60–$70 and noted key management challenges); staff suggested inspectors be provided keys as part of the inspection process. The group also endorsed limiting formal construction-document (plan review) requirements to commercial projects where plan review helps fire marshals verify hood, CFM and exhaust configurations.

Electrical registration and enforcement: the board reviewed language in state law (Title 6, section 103 as discussed in the meeting) that the chair read as preserving local authority to require registrations, permits, fees and inspections to regulate the quality and character of electrical work. Board members agreed a county registration (not a state license) could be used to bar unregistered contractors from working in the county and to provide a report pathway to the state if local action is taken. The group discussed enforcement steps, including using county permit holds, violation reports, and referral to state investigators for license-level sanctions. The board also discussed whether to require a separate certificate of insurance for county registration or to verify insurance via the state licensing record; no final decision on that detail was recorded in the meeting.

Next steps: staff will draft proposed code language and a staff report outlining expected costs (staffing, permit/registration fees) and public benefits for presentation to the county commissioners at a workshop (the board discussed December 2 as the target date, with a possible alternate of December 16). The board also approved a tentative meeting calendar and adjourned.

What the board did not decide: the meeting recorded no final text of a registration ordinance, no firm fee schedule, and no final list of inspection fees or staffing details — those will be part of the staff draft presented to the commissioners. The transcript includes detailed operational points that staff must resolve (for example, whether to require separate electrical inspections when wiring is altered, how to manage locking-cap keys, and whether to require duplicate insurance certificates).
