AB 1341 amends Business and Professions Code §7110 to expand what counts as the “building laws of the state” for purposes of disciplining licensed contractors. The bill explicitly brings prohibitions on the practice or unlicensed practice of architecture, landscape architecture, engineering, geology/geophysics, and land surveying within the set of laws whose willful or deliberate violation may trigger contractor discipline.
The change also recasts several provisions related to structural pest control as part of the state’s building laws. For compliance officers and contractors, the net effect is a broader enforcement perimeter: conduct that risks being treated as unlicensed practice in a design profession can now be actionable under the Contractors State License Law as cause for discipline, increasing overlap with other professional boards and raising new compliance questions for firms that perform design-related work in-house or through subcontractors.
At a Glance
What It Does
The bill revises §7110 to treat specified prohibitions on practicing—or practicing without a license—in architecture, landscape architecture, engineering, geology/geophysics, and land surveying as part of the state’s ‘building laws.’ It also moves provisions on structural pest control into that same definition.
Who It Affects
Licensed contractors under the Contractors State License Board, design professionals and their licensing boards, contractors who perform in-house design or coordinate design subcontractors, and consumers reliant on contractor oversight and licensing enforcement.
Why It Matters
The amendment broadens the set of statutory violations that can trigger CSLB discipline, creating potential enforcement overlap with other boards (architects, engineers, surveyors) and raising compliance risk for contractors who take on design tasks or rely on unlicensed individuals.

What This Bill Actually Does
Under current law the Contractors State License Board (CSLB) can discipline a licensee for willful or deliberate disregard of the state’s building laws. AB 1341 expands what the CSLB may treat as those building laws by explicitly listing prohibitions tied to several design professions.
That means a contractor who willfully ignores rules that prohibit unlicensed practice of architecture, engineering, surveying, landscape architecture, or geology/geophysics can be disciplined under the Contractors State License Law in the same way the board disciplines other building-law violations.
The bill accomplishes this by amending §7110 and adding a short, enumerated list of code sections into the statutory definition of “building laws of the state.” It names specific statutory references (including sections appearing in the Business and Professions Code that govern professional practice and unlicensed practice prohibitions) so that those statutes are treated as part of the building-law framework for contractor discipline. Separately, it reorganizes provisions previously tied to structural pest control so they are explicitly included within the same “building laws” rubric.Practically, the change does not create a new licensing category or substitute the professional licensing boards; rather, it enlarges the set of statutory bases the CSLB can rely on when pursuing disciplinary action against a contractor.
Contractors who perform design work, supervise design subcontractors, or rely on third parties for design services will need to reassess internal controls, delegation practices, and documentation to show they did not willfully run afoul of the newly enumerated prohibitions. For other stakeholders, the amendment raises coordination questions: where conduct touches both contractor scope and a separate profession’s statutory limits, multiple agencies may have concurrent grounds to act, creating potential for duplicative investigations or conflicting remedies.
The Five Things You Need to Know
AB 1341 amends Business and Professions Code §7110 to expand the statutory definition of “building laws of the state” used to trigger contractor discipline.
The bill explicitly incorporates prohibitions tied to the practice or unlicensed practice of architecture, landscape architecture, engineering, geology/geophysics, and land surveying into that definition.
It lists specific statutory references to be treated as building laws, including sections appearing in the Business and Professions Code (for example: 5536; 5536.1(c); 5536.4; 5640; 6787; 7872; 8550/8556; 8792).
Provisions previously described separately for structural pest control are recast and included within the definition of building laws, changing how those violations are categorized for disciplinary purposes.
The amendment expands the bases for administrative discipline by the CSLB; it does not itself create new criminal offenses or establish new penalty schemes—it adds grounds for action under the existing Contractors State License Law framework.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Adds design-profession prohibitions to the list of disciplinary bases
This subsection revises the opening list of statutes and references that, if willfully or deliberately violated, constitute grounds for disciplinary action. Practically, it folds prohibitions that protect architecture, engineering, surveying, landscape architecture, and geology/geophysics into the roster of laws a contractor can be disciplined for violating. For compliance teams this changes the universe of conduct that can be cited in CSLB disciplinary charges.
Defines ‘building laws of the state’ to include enumerated professional-practice sections
Subsection (b) supplies the operative definition by naming particular code sections to be read as part of the state’s building laws. Those enumerated sections are now explicit triggers for contractor discipline instead of being treated as external references, reducing ambiguity about whether violations of those professional-practice statutes fall within the CSLB’s disciplinary reach.
Moves structural pest control rules into the building-law definition
Language previously described separately for the business and practice of structural pest control is reorganized and folded into the list of building laws. That shifts how the statute groups pest control-related violations—now squarely within the building-law category—affecting how the CSLB frames charges that involve pest control work.
Keeps existing references while broadening enforcement perimeter
The bill leaves intact other listed references in §7110 (Civil Code provisions, safety and labor laws, permit issuance, Penal Code section references, etc.) while expanding the definition of building laws. It does not, on its face, alter CSLB’s remedial options or procedural rules; it simply provides additional statutory bases the board may cite when bringing discipline.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Licensed design professionals (architects, engineers, surveyors, landscape architects, geologists/geophysicists): the bill strengthens the statutory basis to challenge unlicensed competition by making related prohibitions enforceable as building-law violations under the CSLB.
- Consumers and property owners: clearer grounds for disciplining contractors who engage in unlicensed design work could reduce risk of unsafe or noncompliant buildings when enforcement is effective.
- Compliant contractors: firms that restrict design work to licensed professionals gain a stronger remedy against competitors who attempt to undercut them by performing regulated design activities without proper licensure.
- CSLB enforcement staff: the statutory clarity gives the board additional, explicit authority to frame cases involving overlapping design-practice conduct as building-law violations.
Who Bears the Cost
- Contractors who provide in-house design services or rely on unlicensed personnel: expanded grounds for discipline increase regulatory risk and may require changes to staffing, contracting, and oversight practices.
- Small contractors and subcontractors: compliance, documentation, and potential licensing costs can disproportionately burden smaller firms that historically handled some design tasks informally.
- Other professional licensing boards (architects/engineers/surveyors): potential for duplicated investigations and administrative coordination burdens if both CSLB and a profession’s board investigate the same conduct.
- CSLB and state agencies: tighter scope for discipline can increase caseloads and require inter-agency coordination, potentially imposing resource and policy-development costs.
Key Issues
The Core Tension
AB 1341 pits two legitimate aims against each other: protecting public safety and licensed professions by expanding enforceable prohibitions, versus creating overlapping regulatory exposure and uncertainty for contractors who perform design-related work—especially smaller firms—without providing clear procedural coordination or bright-line standards to limit overreach.
The bill sharpens enforcement authority but leaves several implementation questions unresolved. First, the statutory trigger remains a mental-standard phrase—“willful or deliberate disregard”—that courts and administrative tribunals have interpreted variably; the change does not define the standard or provide concrete thresholds, so close-case conduct (negligence, mistake, or inadvertent overlap between trade and design work) may still be litigated.
Second, the expansion creates cursorily overlapping jurisdiction: conduct that implicates both contractor scope and a separate profession’s licensing statute could produce parallel CSLB and board investigations, yet AB 1341 does not set out rules for inter-agency cooperation or primacy.
The bill also risks a chilling effect on legitimate, limited design work historically performed by contractors within the statutory scope of contracting. Small firms that once combined trade and minor design tasks may now face heightened risk, prompting either costly licensure, reliance on more expensive outside design professionals, or conservative practices that slow projects.
Finally, because the amendment reorganizes provisions (for example, moving structural pest control items into the building-law bucket) it may require administrative guidance or rulemaking to clarify charging practices and to avoid inconsistent outcomes across cases.
