CSLB discipline

Grounds for CSLB Discipline: §§7107, 7109, and 7110 Explained

The Contractors State License Law lists dozens of grounds for disciplinary action, but three of them account for a large share of what a working contractor actually faces: Business and Professions Code section 7107 (abandonment), section 7109 (willful departure from trade standards or from plans and specifications), and section 7110 (willful or deliberate disregard of building, safety, and labor laws). They overlap, but not completely — and the gaps between them matter. One of the three contains a carve-out for architect-prepared plans that the others do not. This guide, reviewed by Jayson R. Elliott, reads each provision on its own terms and then sets them side by side.

Three provisions, three different targets

Section 7107 is about walking away. Section 7109 is about how the work was performed measured against a standard — either the trade’s standard or the project’s own drawings. Section 7110 is about compliance with law, as distinct from compliance with a plan or a workmanship standard.

That distinction is the practical key. The same job can generate a section 7109 exposure and no section 7110 exposure, or the reverse. A contractor who builds precisely to code but departs materially from the approved drawings has a section 7109 problem, not a section 7110 problem. A contractor who follows the drawings faithfully while those drawings violate the building code has a section 7110 problem that section 7109’s architect exception does not answer.

§7107: abandonment without legal excuse

Section 7107 is the shortest of the three. Abandonment, without legal excuse, of any construction project or operation engaged in or undertaken by the licensee as a contractor is a cause for disciplinary action.

The operative words are “without legal excuse.” The provision does not make leaving a job actionable in itself; it makes leaving a job without a legally sufficient reason actionable. Non-payment, an owner’s material breach, denial of site access, and unsafe conditions are the categories contractors most often have in mind when they stop work — but whether any of them constitutes a legal excuse on particular facts is exactly the question a disciplinary proceeding would decide, and it is fact-specific.

What follows from that is a documentation point rather than a legal one. A contractor who stops work for a reason they believe is legally sufficient should be able to show, later and in writing, what the reason was and when it arose. A stoppage that is well justified but undocumented looks the same in a file as a stoppage that was not justified at all.

§7109: willful departure — two separate subdivisions

Section 7109 is frequently cited as though it were a single rule about workmanship. It is two rules, and they have different elements.

§7109(a): accepted trade standards, and the architect exception

Subdivision (a) makes a willful departure, in any material respect, from accepted trade standards for good and workmanlike construction a cause for disciplinary action — unless the departure was in accordance with plans and specifications prepared by or under the direct supervision of an architect.

That closing clause is the most commercially significant sentence in the provision, and it is narrower than the way contractors typically describe it. It is not a general defense that “the architect approved it.” It applies where the departure from trade standards was itself in accordance with plans and specifications prepared by, or under the direct supervision of, an architect. Plans stamped by an engineer, drawings produced by a designer who is not an architect, or an architect’s verbal sign-off on a field change are not obviously within it. Nor does it reach subdivision (b) or section 7110.

§7109(b): plans and specifications, prejudice, and consent

Subdivision (b) addresses a willful departure from, or disregard of, plans or specifications in any material respect, which is prejudicial to another, without the consent of the owner or the owner’s duly authorized representative and without the consent of the person entitled to have the project completed in accordance with those plans or specifications.

Subdivision (b) therefore carries elements subdivision (a) does not: the departure must be prejudicial to another, and it must be without consent — and the statute contemplates two consents, the owner’s and that of the person entitled to have the work completed to the plans, which are not always the same party. On a project where the owner and the eventual occupant or purchaser are different, that distinction is not academic.

The practical consequence is that documented, authorized changes are the defense that actually maps onto the statute. A field change the owner asked for, confirmed in a written change order, is materially different from the same physical change made on a verbal understanding.

§7110: building, safety, and labor laws — no architect exception

Section 7110 reaches willful or deliberate disregard and violation of the building laws of the state or of any political subdivision, of safety or labor laws, of compensation insurance laws and the Unemployment Insurance Code, and of the Subletting and Subcontracting Fair Practice Act, along with violations of specified Health and Safety Code and Water Code provisions.

Two features distinguish it. First, its subject is legal compliance, not workmanship — the question is not whether the work met a trade standard but whether it violated a law. Second, and consequentially, section 7110 contains no counterpart to section 7109(a)’s architect exception. Building to architect-prepared plans is not, on the face of the statute, an answer to a charge that the completed work violated the building code.

For a contractor, that asymmetry is the single most useful takeaway on this page. Reliance on stamped drawings addresses one exposure and leaves another intact.

Read this table as a map of the statutory text, not as a prediction of how a particular charge would be resolved. Whether an element is satisfied on given facts is a merits question.

What "willful" means, and why it is contested

Three of the license law’s charging provisions turn on willfulness, and sections 7109 and 7110 are two of them. Contractors generally assume the word imports an intent to break the law — that the Board would have to show they knew the requirement and chose to violate it. The prevailing reading is less favorable than that: “willful” in this setting is generally understood to require only a general intent to do the act, not a specific intent to violate the license law or to cause harm. On that reading, a contractor who deliberately performed the work in the way it was performed can satisfy the element even if they believed the approach was acceptable.

This point should be held with some care, however. Commentary in this area notes that appellate decisions have not been uniform on what “willfulness” and materiality require under these provisions, and the term is not defined in the statute. The general-intent reading is the safer planning assumption for a contractor precisely because it is the less favorable one — but it is not a settled rule that this page can state as though the question were closed. Anyone facing an actual charge should have counsel assess which authorities apply to their facts.

What this means practically

Four things follow from the way these provisions are written:

A contractor who has already received CSLB correspondence should read the companion guide on responding to a complaint before taking any step that puts a written account on the record.

Before you ask

Questions contractors ask first.

What are the main grounds for CSLB disciplinary action against a contractor?

The Contractors State License Law lists many grounds, but Business and Professions Code sections 7107, 7109, and 7110 account for a large share of contractor exposure: abandonment of a project without legal excuse, willful departure from accepted trade standards or from plans and specifications, and willful or deliberate disregard of building, safety, labor, and compensation insurance laws. Other provisions address related conduct such as fund diversion and late payment to subcontractors.

Does following architect-approved plans protect a contractor from CSLB discipline?

Only partially. Business and Professions Code section 7109(a) excepts a departure from accepted trade standards where the departure was in accordance with plans and specifications prepared by or under the direct supervision of an architect. That exception does not appear in section 7109(b) or in section 7110, so architect-prepared plans do not answer a charge that the completed work violated building or safety laws.

What counts as abandonment under BPC §7107?

Business and Professions Code section 7107 makes abandonment of a construction project or operation without legal excuse a cause for disciplinary action. The provision does not define which excuses are legally sufficient, so whether a particular stoppage — for non-payment, denial of site access, unsafe conditions, or an owner’s breach — qualifies is a fact-specific question resolved on the record of that matter.

What is the difference between BPC §7109 and §7110?

Business and Professions Code section 7109 measures the work against a standard — accepted trade standards under subdivision (a), or the project’s plans and specifications under subdivision (b). Section 7110 measures conduct against the law, reaching willful or deliberate disregard of building laws, safety and labor laws, compensation insurance laws, and specified Health and Safety Code and Water Code provisions. Work can violate one without violating the other.

Does "willful" mean the contractor intended to break the law?

Under Business and Professions Code sections 7109 and 7110, the prevailing understanding is that willfulness requires only a general intent to perform the act rather than a specific intent to violate the license law. The term is not defined in the statute and appellate treatment has not been uniform, so a contractor facing a charge should not assume either the favorable or the unfavorable reading applies to their facts without counsel reviewing the authorities.

Can a contractor be disciplined for a departure the owner agreed to?

Business and Professions Code section 7109(b) makes consent an express element: the departure must be without the consent of the owner or the owner’s duly authorized representative and without the consent of the person entitled to have the project completed in accordance with the plans. Because the statute contemplates both, documented written consent from the correct parties matters more than an informal understanding on site.
