California CSLB Metal Products Contractor D-24 / C-61 Attorney Fee Petition Mechanics: Tyler Odyssey Civil Complaint Date as Primary Welch Anchor, CSLB License Check (D-24 / C-61) as Secondary Anchor (THE ONLY D-24 Metal Products Page in This Series — DISTINCT FROM C-23 Ornamental Metals and DISTINCT FROM D-25/C-61 Ornamental Iron — ONLY Page With ANSI/SDI A250.8 Specification for Standard Steel Doors and Frames Advisory [THE ONLY PAGE in the Fee-Petition-Mechanics Series With an ANSI/SDI A250.8 Advisory — PURE KETCHUM] and AISI S100-16 North American Specification for Cold-Formed Steel Structural Members Advisory; Commercial Building Permit CBC § 105.1 as Second Institutional Anchor; ADA Toilet Partition 10 lbs Door Closing Force ADA Title II Complaint $18,500 Barrier Removal / CMU Hollow-Core Anchor Pull-Out 12-Locker Bank Topple $14,500 Property Damage / Seismic Unanchored AISI S100 Display Fixture Mw 5.4 Tip-Over $34,000 Merchandise Damage Personal Injury Three-Track Harm; Bus. & Prof. Code § 7031(b) Disgorgement), CLRA § 1780 Mandatory Attorney Fees

Statutory Framework: Bus. & Prof. Code § 7028, D-24 / C-61 Metal Products, ANSI/SDI A250.8 Advisory, AISI S100-16 Advisory, Commercial Building Permit Advisory, § 7031(b) Disgorgement, and CLRA § 1780 Mandatory Attorney Fees

California Business and Professions Code § 7028 prohibits unlicensed contracting. The CSLB D-24 (Metal Products) limited specialty designation under C-61 authorizes: fabrication and installation of metal toilet partition systems including overhead-braced, floor-mounted, and floor-to-ceiling configurations in commercial restrooms; installation of metal locker systems including single-tier, double-tier, and athletic lockers in gymnasiums, schools, and commercial facilities; installation of metal shelving systems including industrial wire shelving, boltless steel shelving, and steel rivet shelving in warehouses and commercial storage applications; fabrication and installation of metal merchandise display fixtures including free-standing gondola shelving, wall-mounted display panels, and retail display cases; fabrication of light metal equipment bases for commercial kitchen equipment and retail checkout counters; and installation of metal access panels, metal louvered doors, and metal equipment enclosures in commercial interiors. D-24 does not cover: structural ornamental metalwork for commercial buildings requiring engineering review (requires C-23 Ornamental Metals); residential ornamental iron gates, railings, and fence panels (requires D-25/C-61); structural steel framing for buildings (requires C-51 Structural Steel); or welding and fabrication of pressure vessels or process piping (requires specialized trades). D-24 is distinct from C-23 because C-23 covers structural and exterior ornamental metalwork with engineering involvement, and D-24 covers non-structural commercial interior products.

ANSI/SDI A250.8 Specification for Standard Steel Doors and Frames (published by the Steel Door Institute) is a private industry organization publication — NOT a California statute, NOT California administrative code, NOT a federal regulation creating mandatory civil attorney fees. ANSI/SDI A250.8 is applicable to hollow metal frames used in metal toilet partition systems and metal locker frame construction and specifies: frame material gauge — minimum 16 gauge (0.0598-inch steel) for standard commercial applications and minimum 14 gauge (0.0747-inch) for heavy-duty applications such as high-use public restroom partition frames and athletic locker frames; anchor spacing — maximum 24 inches on center for frame anchors with a minimum of three anchors per jamb; steel door frames for partition openings must have concealed anchors that engage the masonry or stud framing behind the partition surface — surface-applied fasteners are not acceptable for hollow metal partition frames in occupied commercial spaces; corner joints in hollow metal frames must be continuously welded and ground smooth to eliminate stress concentration points; factory-applied rust inhibitive primer coat required before delivery — field primer touch-up required within 24 hours of installation; dimensional tolerances — frame opening height and width must be within ±1/32 inch of specified nominal dimensions; weld quality must meet AWS D1.3 structural sheet steel welding requirements at all structural joints. PURE KETCHUM: ANSI/SDI A250.8 is a private Steel Door Institute industry publication — it creates no private civil right of action and no mandatory attorney fee-shifting mechanism for persons harmed by unlicensed California D-24/C-61 metal products contractors.

AISI S100-16 North American Specification for the Design of Cold-Formed Steel Structural Members (published by the American Iron and Steel Institute) is a private technical standard — NOT a California statute, NOT California administrative code, NOT a federal regulation. AISI S100-16 is applicable to cold-formed steel framing used in metal shelving systems, display fixtures, and equipment bases and specifies: minimum yield strength — Fy = 33 ksi for ASTM A653 Grade 33 cold-rolled galvanized steel used in light-gauge commercial shelving and display fixtures; effective width concept — AISI S100 uses an effective width methodology for stiffened compression elements to account for local buckling, reducing the effective section properties below the gross section area when the slenderness ratio exceeds the limit; connection requirements — #12-14 self-drilling screws with minimum edge distance 3/8 inch and maximum spacing 12 inches on center for cold-formed steel-to-steel connections at frame joints and shelf supports; deflection limit — L/240 for shelving and display fixture horizontal members under service load to prevent visible sagging and merchandise displacement; seismic requirements for California Zone 4 — unrestrained cold-formed steel shelving racks and display fixtures must be anchored to the floor structure or wall framing to resist a minimum 0.3g lateral acceleration load per ASCE 7 seismic design requirements for nonstructural components — anchor design must account for the full weight of the fixture and maximum merchandise load. PURE KETCHUM: AISI S100-16 is a private American Iron and Steel Institute technical standard — it creates no private civil right of action and no mandatory attorney fee-shifting mechanism; seismic anchor omission generating property damage or personal injury is recoverable as CLRA actual damages when the contractor is unlicensed.

Primary Welch Anchor: Tyler Odyssey Civil Complaint Filing Date

The Tyler Odyssey civil complaint filing date is the primary Welch temporal anchor for D-24 metal products matters. The attorney files after confirming CSLB C-61/D-24 license status, reviewing commercial building permit and rough inspection records, measuring toilet partition door closing force and inspecting ADA compliance, confirming locker frame anchor engagement in CMU, inspecting display fixture base anchoring, retaining a CASp inspector and structural engineer, and serving the CLRA § 1782 demand. The CSLB D-24/C-61 License Check date is the secondary Welch anchor. Ketchum v. Moses 24 Cal.4th 1122 (2001); PLCM Group Inc. v. Drexler 22 Cal.4th 1084 (2000).

Secondary Anchor: CSLB License Check (D-24 / C-61 Metal Products) — THE ONLY D-24 Specialty Anchor in the Fee-Petition-Mechanics Series

The CSLB License Check must confirm the C-61/D-24 Metal Products limited specialty designation — distinct from C-23 (Ornamental Metals full specialty for structural commercial exterior ornamental metalwork) and distinct from D-25/C-61 (Ornamental Iron for residential ornamental iron gates and railings). Three scenarios generate § 7028 liability: (a) no CSLB license at all; (b) expired, suspended, or revoked C-61/D-24 license; (c) a general contractor or handyman who performs commercial toilet partition installation or retail display fixture installation without holding the D-24 limited specialty. This page is THE ONLY D-24 Metal Products specialty anchor in the fee-petition-mechanics series.

Billing Gap 1 — CSLB D-24/C-61 License Check, Commercial Building Permit Review, ANSI/SDI A250.8 Frame Inspection, AISI S100-16 Seismic Anchor Documentation, and § 1782 Demand (5.25 hrs/yr = $1,575–$2,625)

The first billing gap covers pre-complaint advisory for D-24 metal products matters.

• Searching CSLB License Check for C-61/D-24 designation and establishing the secondary Welch anchor: confirming D-24 limited specialty presence or absence; evaluating C-23 and D-25 distinctions; confirming license status, bond, and workers compensation insurance.
• Reviewing AHJ commercial building permit and rough inspection records — second institutional anchor: obtaining the commercial building permit and inspection record for the metal products installation; confirming whether the AHJ inspector reviewed partition frame anchor engagement, locker fastening to CMU, and display fixture seismic anchoring; reviewing any correction notices related to CBC § 1604 structural stability requirements.
• Inspecting ANSI/SDI A250.8 frame compliance at toilet partition and locker installations: measuring toilet partition door closing force with a spring scale; inspecting frame anchor engagement in CMU by probing behind base plates; measuring frame gauge at accessible edges; reviewing corner joint weld quality; confirming concealed anchor configuration.
• Documenting AISI S100-16 seismic anchor compliance at display fixtures and shelving: inspecting display fixture base plates for anchor bolts; applying lateral load test to confirm fixture restraint; retaining a structural engineer to calculate required seismic anchor capacity for fixture weight and merchandise load at 0.3g lateral acceleration.
• Serving CLRA § 1782 demand incorporating ANSI/SDI A250.8 and AISI S100-16 advisory analysis: demand specifies D-24 unlicensed contracting, identifies three harm tracks, demands disgorgement under § 7031(b), and specifies CLRA § 1780 mandatory attorney fees.

Billing Gap 2 — Active Litigation: CASp Inspector, Structural Engineer, and Three-Track Damage Quantification (4.00 hrs/yr = $1,200–$2,000)

The second billing gap covers expert coordination across the three D-24 harm tracks.

• Retaining a CASp inspector for Track 1 ADA toilet partition barrier: CASp inspector conducts comprehensive ADA access inspection of the toilet partition system; documents all barriers including door closing force, clear width, turning radius, hardware type and mounting height; quantifies barrier removal scope and cost including partition door hardware replacement, stall width adjustment if needed, and hardware height corrections; provides written CASp inspection report as required for ADA Title II complaint response.
• Retaining a structural engineer for Track 2 CMU locker anchor pull-out: engineer documents CMU block type (hollow-core versus solid) and the anchor screw specification used; calculates the pull-out capacity of 3/8-inch concrete screws in hollow CMU face shell versus ANSI/SDI A250.8 required anchor engagement; quantifies the dynamic loading from locker door slamming over 14 months as cumulative fatigue load on the anchor; provides CBC § 1604 structural stability opinion and calculates locker bank topple energy and property damage mechanism.
• Retaining a structural engineer and merchandise appraiser for Track 3 seismic display fixture: structural engineer calculates fixture overturning moment under 0.3g seismic acceleration and the required base anchor capacity; documents absence of anchoring and provides opinion on AISI S100-16 seismic restraint requirement; merchandise appraiser inventories and values the $34,000 merchandise damaged in the fixture tip-over; personal injury expert quantifies damages from retail customer injury.
• Settlement valuation incorporating all three harm tracks and CLRA § 1780 mandatory attorney fees: D-24 three-track settlement demand integrates ADA barrier removal costs, locker property damage, and seismic merchandise damage and personal injury with CLRA mandatory attorney fees.

Billing Gap 3 — CLRA § 1780 Fee Petition, Pure Ketchum Multiplier, Lodestar Documentation, and Missouri v. Jenkins Fees-on-Fees (4.00 hrs/yr = $1,200–$2,000)
