01 The project

The starting point is the work itself — Solar Installation in North Dakota. The job determines which trades are involved, and the trades determine which license classifications may be required.

02 Jurisdiction

This project is evaluated for North Dakota — the four-class license state. A construction contractor holds a ch. 43-07 contractor license in a class (A/B/C/D) covering the single-contract value once a job exceeds $4,000, with liability insurance and WSI but no exam and no state bond; electrical (ch. 43-09) and plumbing (ch. 43-18) run through their own credentials, and the building permit is local. North Dakota jurisdiction page.

Limitation — local permit rules stay unknown; the owner question is open

Permit fees, local construction rules and any municipal licensing were not researched and remain LOCAL_AUTHORITY_REQUIRED. The owner-occupant exemption basis is open (CONFLICT-ND-001) and returns NOT_DETERMINED when it is not confirmed — never a guess. State requirements are not the complete story for any locality.

03 Trade → license

Relations below are recorded per state — only this jurisdiction's classifications are shown.

Trades involved: Solar, Electrical.

May require ELECTRICAL-CONTRACTING — Electrical Contracting (master, class B or power limited electrician contracting) reported S-ND-SEB-ELEC-CONTRACTING rule ND-SOLAR-CREDENTIAL
The default answer: there is NO standalone solar license in North Dakota, so a hired rooftop PV install is electrical work — a contracting master (or power limited) electrician plus the ch. 43-09 business prerequisites. 'reported' because the conclusion is assembled from the electrical scope plus the absence of a solar credential (SCOPE-ND-NO-SOLAR), not a single verbatim sentence (research §N.4).
Component basis MASTER-ELECTRICIAN — Master Electrician (may contract electrical work) confirmed S-ND-SEB-ELEC-CONTRACTING rule ND-ELEC-CONTRACT
The individual who must contract and be responsible for the wiring — a master or power limited electrician (NDSEB).
Alternative path CLASS-B — Class B Contractor License (single contract up to $500,000) confirmed S-ND-43-07-02 rule ND-LICENSE-REQUIRED
The general building scope of a PV project (racking, roof work, general construction) may also require a ch. 43-07 contractor license of a covering class when the single-contract value exceeds $4,000.

04 Scope

What the official sources say about the work involved — typed assertions, never a boolean "covers". Interpretations are marked as such.

Officially excluded CLASS-B Single Contract Projects Above 500000 (may_not_perform) NDCC 43-07-07(1)(b) S-ND-43-07-07
The class ceiling decides public-bid eligibility too (43-07-12).
Officially included CLASS-B Single Contract Projects Up To 500000 (may_perform) NDCC 43-07-07(1)(b) S-ND-43-07-07
The positive half of the class-B ceiling; the exclusion is SCOPE-ND-CLASS-B-LIMIT.
Requires another classification solar-installation Electrical Contracting Credential No Solar Specific License (requires) NDCC ch. 43-09; NDSEB Electrical Contracting Guidelines S-ND-SEB-ELEC-CONTRACTING
Project-scope row (no solar classification exists to attach to). 'reported' because the conclusion is assembled from the electrical scope plus the absence of a solar credential, not from a single verbatim sentence (research §N).
Officially included ELECTRICAL-CONTRACTING Electrical Wiring Installation Under A Master Or Power Limited Electrician (may_perform) NDCC ch. 43-09; NDSEB Electrical Contracting Guidelines S-ND-SEB-ELEC-CONTRACTING
Electrical contracting is its own credential family — the contractor license alone does not authorize it (rule ND-ELEC-CONTRACT).

05 Requirements

Requirement	Kind	Statement	Source
No standalone solar license — PV installation is electrical contracting NDSEB Electrical Contracting Guidelines + Secretary of State Contractors page (read 2026-10-05)	license	North Dakota issues no solar-specific contractor credential: the NDSEB licensing scheme covers electrical wiring and apparatus installation and the Secretary of State's list of specialized licenses names only the Electrical Board, the Plumbing Board and other non-solar programmes. A hired rooftop photovoltaic install is therefore electrical work that requires a contracting master (or power limited) electrician and the electrical-contracting business prerequisites under ch. 43-09, not a 'solar license' that does not exist.

The Secretary of State restates the trigger: 'When the cost, value, or price of a job exceeds $4,000, the person doing the work must be licensed as a contractor in North Dakota (NDCC ch. 43-07). This includes subcontractors, general contractors, public contractors, and nonresident contractors.' Acting without the license is a class A misdemeanor (43-07-02(2)).

06 Rule: ND-SOLAR-CREDENTIAL

North Dakota issues no standalone solar license: rooftop photovoltaic installation is electrical work under ch. 43-09, requiring a contracting master or power limited electrician and the electrical-contracting business prerequisites. This rule returns NOT_DETERMINED when the solar-work fact is missing. Marked 'reported' because the conclusion is assembled from the electrical scope plus the absence of a solar credential.

Outcome	Conclusion	Caveats
solar-electrical-required	electrical_contracting_credential_required	The general building scope of a PV project may also need a ch. 43-07 contractor class when the single-contract value exceeds $4,000. No solar tax or interconnection rule was researched (NOT_VERIFIED).

07 Rule: ND-ELEC-CONTRACT

NDSEB / NDCC ch. 43-09: only a master or power limited electrician may enter a contract to install electrical wiring; a class B electrician may only contract farmstead wiring or one/two-family residential wiring in cities of 2,500 or fewer. A contracting electrical business must also register and hold a ch. 43-07 contractor license and file the NDSEB electrical-contracting application with liability insurance of at least $500,000. Missing facts yield NOT_DETERMINED.

08 Rule: ND-LICENSE-REQUIRED

NDCC 43-07-02(1): a person may not act as a contractor in North Dakota when the cost, value or price PER JOB exceeds $4,000 without a state contractor license from the Secretary of State, nor maintain a claim or suit on that work. The definition of 'contractor' is broad (43-07-01(1)) and includes subcontractors, public contractors and nonresident contractors. Acting without the license is a class A misdemeanor plus a civil penalty up to three times the 43-07-07 fee. Exemptions and the owner question are SEPARATE rules (ND-MINOR-4K, ND-OWNER-PROPERTY). Missing facts yield NOT_DETERMINED.

Outcome	Conclusion	Caveats
license-required	contractor_license_required	Test ND-MINOR-4K first — a single job at or below $4,000 does not itself trigger the duty. Test ND-OWNER-PROPERTY — the owner-occupant question is OPEN (CONFLICT-ND-001) and returns NOT_DETERMINED when the exemption basis is not confirmed. The class must cover the single-contract value (rule ND-CLASS-SCOPE) and public bids must enclose the class license (43-07-12). Electrical and plumbing work need their OWN trade credentials on top (rules ND-ELEC-CONTRACT, ND-PLUMB-MASTER).
license-held	license_already_held	Holding a contractor license is not holding a trade credential — electrical (ch. 43-09) and plumbing (ch. 43-18) work needs its own credentials.
within-threshold	no_license_trigger_at_or_below_4000	Repeated jobs can still be 'engaging in the business of construction' (43-07-01(1)) — evaluate ND-MINOR-4K's second branch. Electrical/plumbing work is regulated separately regardless of price (ND-ELEC-CONTRACT, ND-PLUMB-MASTER).
not-a-contractor	outside_chapter_43_07	43-07-08 exceptions remain the only enumerated ones: government representatives and unaffixed fabricated products.

09 No solar license — the electrical credential

Question	North Dakota answer	Source
Generic solar license	none exists — the credential is electrical (rule ND-SOLAR-CREDENTIAL)	S-ND-SEB-ELEC-CONTRACTING
Default credential path	a contracting master or power limited electrician plus the electrical-business prerequisites (rule ND-ELEC-CONTRACT)	S-ND-SEB-ELEC-CONTRACTING
General building scope	may also need a ch. 43-07 class license above $4,000 (rule ND-LICENSE-REQUIRED)	S-ND-43-07-02
Business prerequisites	SOS registration + contractor license + NDSEB Application for Electrical Contracting + $500,000 insurance	S-ND-SEB-ELEC-CONTRACTING

10 Permit and verification layer

North Dakota separates the credential from the permit: the STATE decides who may work (the ch. 43-07 license and the ch. 43-09 / ch. 43-18 trade credentials), while the city or county issues the building permit. NDCC 43-07-24 makes the contractor supply its license number and the issuer enter it, and 43-07-12 makes public bids enclose the class license. The permit and its rules are local — LOCAL_AUTHORITY_REQUIRED. S-ND-43-07-24
