The NC 90-day qualifier rule

N.C. Gen. Stat. § 87-10(c1) provides: "If the qualifier or qualifying party shall cease to be connected with the licensee, then the license shall remain in full force and effect for a period of 90 days. After 90 days, the license shall be invalidated, however the licensee shall be entitled to return to active status pursuant to all relevant statutes and rules promulgated by the Board. However, during the 90-day period described in this subsection, the licensee shall not bid on or undertake any additional contracts..." This 90-day rule applies specifically to NC general contractor licenses under Chapter 87 Article 1. Other NC contractor licensing boards (plumbing/heating/fire sprinkler under Article 2, electrical under Article 4, landscape contracting under Chapter 89D) administer separate licensing frameworks with their own rules on qualifier identification, license assignment, and operational continuity. The specific statutory language for each trade is addressed in the trade-specific guidance section below.

Replacement-qualifier qualification can take substantial time depending on the trade, candidate experience, board examination scheduling, and the board's review process, and in our experience frequently exceeds the 90-day window. The candidate must satisfy the experience requirements for the relevant classification under the applicable board's rules, pass the relevant board examination, satisfy the board's fitness review and criminal background check, and be approved by the board to serve as the qualifier for the entity. Starting that process at the 90-day countdown is functionally too late.

Planning solutions

Every NC trades business should have a documented qualifier-succession plan in place well before the founding qualifier's expected exit. The integrated planning approach addresses four points:

• Identification of a second qualifier within the entity, qualified through the appropriate Board, employed by the entity, and ready to step in if the primary qualifier exits. The second qualifier may be the founder's child, a key employee being groomed for ownership succession, or a non-owner employee whose Board-issued license the entity maintains as a backup.

• Coordination with the operating agreement and buy-sell agreement. The operating agreement should authorize the surviving members or manager to take immediate action on replacement-qualifier qualification without requiring further consent, and should specify the consequences if the entity loses its license.

• Coordination with personal estate documents. The deceased qualifier's will or trust should not include provisions that conflict with the operating agreement's qualifier-replacement protocol. The integrated drafting approach prevents these conflicts.

• Multi-trade businesses need cross-licensing planning. A NC trades business operating in multiple licensed categories (for example, a mechanical contractor with HVAC, plumbing, and electrical work) typically requires separate qualifiers for each licensed category. Each board has its own continuity mechanics when a qualifier's connection to the licensee ends: § 87-10(c1) provides a 90-day grace period for general contractor licenses, SBPHFSC governs continuity for plumbing and Heating Group licenses under § 87-21 and its rules, and NCBEEC requires prompt notification under § 87-43.2 for electrical licenses with immediate cancellation if no listed qualifier remains. Coordinated planning across these rules matters for multi-trade businesses.

The narrow successor-eligibility rule for plumbing and heating

Plumbing and heating businesses face an additional succession constraint under N.C. Gen. Stat. § 87-21(b1). The license number may be assigned to a successor only if the successor has been employed by the initial licensee's plumbing and heating company for at least 10 years, or is a lineal relative, sibling, first cousin, nephew, niece, daughter-in-law, son-in-law, brother-in-law, or sister-in-law of the initial licensee. This narrow rule does not apply to general contractor or electrical licenses; it is specific to NC plumbing and heating.

Most PE acquirers, most strategic acquirers, and most non-family successor employees with less than 10 years' tenure run into the same problem, and let me be very clear with you on what that means in practice. The acquirers, most strategic acquirers, and most non-family successor employees with less than 10 years' tenure cannot receive the license number through assignment. The acquirer must obtain its own license through its own qualifier, which requires the acquirer to identify, employ, and qualify a properly licensed individual through the Board's examination and approval process. The selling owner's license number is personal to the licensee and assignable only within the narrow categories the statute permits. This shapes how PE transactions in NC plumbing and heating are structured, including how operational continuity is maintained during the transition and how the acquirer's replacement qualifier is brought in.

The NC private equity consolidation wave in trades

The HVAC, plumbing, electrical, and mechanical trades are experiencing the most aggressive private equity consolidation cycle the sectors have ever seen. NC has been a major focus of this activity, with notable NC-anchored transactions including:

• Service Logic, Charlotte NC headquartered with more than 140 locations and over 5,000 technicians, sold to Bain Capital and Mubadala Investment Company on December 16, 2025, previously owned by Leonard Green & Partners.

• Crete United (formerly Crete Mechanical Group; rebranded in early 2024), Charlotte-based national HVAC/electrical/plumbing/building automation platform, backed by Charlotte-based Ridgemont Equity Partners, with debt financing reported by industry sources to include Ares Management Corporation and Churchill Asset Management.

• ACME Plumbing Company, Durham NC fourth-generation commercial and residential plumbing business, acquired by Charlotte-based Broadtree Partners on January 7, 2026 as the platform for Broadtree's mechanical, electrical, and plumbing services strategy.

• Century Contractors LLC, Matthews NC mechanical and pipe fabrication, acquired by Comfort Systems USA (NYSE: FIX) on January 1, 2025.

• Pro Plumbing Services, Lexington NC, acquired by Southern HVAC Corporation in 2022 as a Piedmont Triad bolt-on.

• Airo Mechanical, Mooresville NC HVAC and plumbing installation, acquired by CCMP Growth Advisors on August 7, 2025.

• Smith's Refrigeration, Lumberton NC mechanical contractor, joined the PremiStar platform.

Both an immediate liquidity event (cash at closing) and a continued business interest (rollover equity) are at stake in these transactions, and the math is pretty simple on what that means for the seller. The transaction structures these PE platforms use produce both pieces (cash at closing) and continued business interest (rollover equity, which may qualify for tax-deferred treatment under IRC § 351 depending on transaction structure), and both pieces must be incorporated into the seller's personal estate plan. In our experience, the period of one to three years before a contemplated sale tends to be the most productive window for tax-savings structuring: pre-transaction gifting to family members and trusts at pre-PE-exit valuations, GRAT funding, IDGT sales of pre-transaction equity, possible C-corp conversion for IRC § 1202 qualified small business stock analysis, and other techniques that can preserve substantial value through the transaction. Owners who begin this planning at the letter-of-intent stage have less room to work with than owners who begin earlier.

What we handle for NC trades businesses

NC trades business succession is best handled as a set of coordinated drafting deliverables rather than as a single document, and I want to strongly encourage you to think about it that way. rather than as a single document. The Walls Law Group's contractor and trades practice is organized around the integrated drafting principle, with deliverables scoped to the size and complexity of each business:

• Operating agreement with trades-specific provisions. Qualifier identification and replacement protocol, license-loss-trigger provisions, cross-license operating arrangements for multi-trade businesses, full buy-sell architecture, and coordination with personal estate documents.

• Funded buy-sell agreement. Life insurance funding for death-trigger redemption, disability insurance funding for disability-trigger redemption, valuation methodology appropriate to the trade, qualifier-loss and license-loss triggers, and Chapter 44A lien-aware indemnification provisions.

• Multi-entity restructuring. For larger trades businesses, separation of operating, real estate, equipment, and holding entities to provide asset protection, succession flexibility, and tax planning opportunities. The structure typically uses LLCs under Chapter 57D with S-corp tax elections under IRC § 1362.

• Personal estate documents. Will, revocable living trust, healthcare power of attorney under NC Chapter 32A, durable financial power of attorney under NC Chapter 32C, all coordinated with the business documents.

• Specialty trusts as needed. ILIT for life insurance, GRAT or IDGT for equity transfer at pre-PE-exit valuations, dynasty trust for multi-generational planning, and qualified subchapter S trust (QSST) or electing small business trust (ESBT) for trusts holding S-corp equity.

• PE transaction counsel. For owners actively engaged in PE transaction discussions: letter-of-intent terms, purchase agreement representations and warranties, IRC § 1202 QSBS analysis, § 105-154.1 NC PTE election interaction with the transaction, rollover equity structure under IRC § 351, employment and non-compete terms, earnout structure, and post-closing equity governance.
