California CSLB Dry Wall Contractor D-19 / C-61 Attorney Fee Petition Mechanics: Tyler Odyssey Civil Complaint Date as Primary Welch Anchor, CSLB License Check (D-19 / C-61) as Secondary Anchor (THE ONLY D-19 Dry Wall Page in This Series — DISTINCT FROM C-9 Drywall Full Specialty — ONLY Page With GA-214 Recommended Levels of Gypsum Board Finish Advisory [THE ONLY PAGE in the Fee-Petition-Mechanics Series With a GA-214 Advisory — PURE KETCHUM] and ASTM C840 Standard Specification for Application and Finishing of Gypsum Board Advisory; AHJ Residential Building Permit and Drywall Inspection as Second Institutional Anchor; Type X Drywall Fire Assembly Failure Certificate of Occupancy Withheld / Non-MR Gypsum Board Bathroom Shower Mold / Level 3 vs Level 5 Finish Dispute Real Estate Transaction Three-Track Harm; Bus. & Prof. Code § 7031(b) Disgorgement), CLRA § 1780 Mandatory Attorney Fees

Statutory Framework: Bus. & Prof. Code § 7028, D-19 / C-61 Dry Wall, GA-214 Advisory, ASTM C840 Advisory, Residential Building Permit Advisory, § 7031(b) Disgorgement, and CLRA § 1780 Mandatory Attorney Fees

California Business and Professions Code § 7028 prohibits unlicensed contracting. The CSLB D-19 (Dry Wall) limited specialty designation under C-61 authorizes: installation of gypsum wallboard (drywall) on wood stud walls and ceilings in new residential construction and room additions; installation of gypsum board on metal stud framing in residential remodels; tape and joint compound (mud) application including taping, bedding, topping, and finish coat application; texture application including orange peel, knockdown, Santa Barbara skip trowel, and smooth skim coat finishes; removal of water-damaged or mold-affected gypsum board down to the stud framing; and installation of replacement gypsum board, including moisture-resistant board in wet areas and fire-rated Type X board in fire-separation applications identified on residential building plans. D-19 does not cover: design or installation of commercial fire-rated partition assemblies (requires C-9 Drywall); installation of exterior gypsum sheathing as part of a rainscreen cladding system (requires C-9 or C-17 Glazing); spray application of intumescent fireproofing to structural steel (requires C-9 or C-15); acoustical ceiling tile systems (requires C-9 or C-61/D-40 Acoustical Tile); or exterior insulation and finish system (EIFS) application (requires C-35 Lathing and Plastering). D-19 is distinct from C-9 because C-9 covers the full specialty including commercial fire-rated partition engineering, steel stud structural framing, and exterior envelope systems.

GA-214 Recommended Levels of Gypsum Board Finish (published by the Gypsum Association) is a private trade association publication — NOT a California statute, NOT California administrative code, NOT a federal regulation creating mandatory civil attorney fees. GA-214 defines six levels of gypsum board surface preparation and finishing: Level 0 (no taping, finishing, or accessories required — temporary construction or areas to be concealed); Level 1 (framing above finished ceilings, concealed areas, fire-rated assemblies where appearance is not critical — tape embedded in joint compound, tool marks and ridges acceptable); Level 2 (substrate for ceramic tile, stone, or paneling; garage walls; warehouses; storage areas — tape embedded, joint compound applied to all fastener heads, no surface texturing or sanding required); Level 3 (surfaces to receive heavy-texture finish applications such as skip trowel, slap brush, or medium orange peel; or surfaces to receive flat paint only — one additional coat over tape and fastener heads, sanded, tool marks not acceptable); Level 4 (surfaces to receive smooth-texture flat paint, light-texture applications including fine orange peel; surfaces in normal lighting conditions; required for most residential sales construction — two additional coats over tape and fastener heads, sanded, all tool marks and ridges completely removed); Level 5 (highest quality finish — skim coat of joint compound or finish plaster applied over the entire surface; required for gloss, semi-gloss, and enamel paint applications; required for critical lighting conditions; required for premium residential construction and luxury real estate — all joints, fastener dimples, and ridges buried under the skim coat, surface uniformly smooth). PURE KETCHUM: GA-214 is a private Gypsum Association trade association publication — it creates no private civil right of action and no mandatory attorney fee-shifting mechanism for persons harmed by unlicensed California D-19/C-61 drywall contractors.

ASTM C840 Standard Specification for Application and Finishing of Gypsum Board (published by ASTM International) is a private technical standard — NOT a California statute, NOT California administrative code, NOT a federal regulation. ASTM C840 specifies: fire-rated assemblies — 5/8-inch Type X gypsum board is required for fire-resistance-rated walls and ceilings, including the 2-hour residential garage-to-dwelling separation; moisture-resistant (MR) gypsum board placement — MR board is required in wet areas within 6 inches of the floor, within 48 inches of shower and bathtub units, and on all surfaces to receive ceramic tile or other hard-surface tile in wet locations; screw spacing — maximum 12 inches on center for ceiling applications, maximum 16 inches on center for wall applications; end butt joint staggering — end butt joints (non-tapered joints perpendicular to framing) must be staggered a minimum of 16 inches from adjacent courses; moisture content before finishing — gypsum board moisture content must not exceed 0.5% by weight before joint compound application and finishing (boards stored flat and elevated above concrete floor to prevent moisture absorption); maximum 1/8-inch offset between adjacent board surfaces at tapered joints; back-blocking required for unsupported butt joints longer than one board width. PURE KETCHUM: ASTM C840 is a private ASTM International standard — it creates no private civil right of action and no mandatory attorney fee-shifting mechanism; violations generating CBC code deficiencies are recoverable as CLRA actual damages.

Three Unique Distinctions in the Fee-Petition-Mechanics Series

• THE ONLY PAGE IN THE FEE-PETITION-MECHANICS SERIES with GA-214 RECOMMENDED LEVELS OF GYPSUM BOARD FINISH ADVISORY — private Gypsum Association trade association publication; Level 0 no taping or finishing; Level 1 tape embedded tool marks acceptable; Level 2 tile substrate garage; Level 3 heavy texture or flat paint only; Level 4 smooth texture flat paint normal lighting typical residential sales construction; Level 5 skim coat full surface gloss semi-gloss enamel and critical lighting premium residential; PURE KETCHUM — GA-214 is a private Gypsum Association trade association publication, not a California statute, not California administrative code, creating no private civil right of action and no mandatory attorney fee-shifting mechanism; finish level disputes are recoverable as CLRA actual damages when the D-19 contractor is unlicensed: the GA-214 advisory generates pre-complaint research hours: (a) confirming CSLB C-61/D-19 license status at contractors.ca.gov; (b) reviewing the construction contract or scope of work for specified finish level language — confirming whether the contract specifies Level 4, Level 5, or a specific texture type; (c) inspecting all finished surfaces under raking light at multiple angles using a portable work light held parallel to the surface — documenting visible tool marks, ridges, tape edges showing through, fastener dimples visible, and surface texture inconsistencies that indicate a Level 3 or lower finish was applied; (d) photographically documenting surface defects at each wall and ceiling area; (e) retaining a licensed drywall finishing contractor or construction defect expert to provide a written opinion on the GA-214 finish level actually installed versus the level specified; (f) obtaining a competitive bid for Level 5 skim coat remediation over all deficient surfaces to quantify actual damages.
• THE ONLY PAGE IN THE FEE-PETITION-MECHANICS SERIES with ASTM C840 STANDARD SPECIFICATION FOR APPLICATION AND FINISHING OF GYPSUM BOARD ADVISORY — private ASTM International standard; 5/8-inch Type X required for fire-resistance-rated assemblies; moisture-resistant MR board required within 6 inches of floor, within 48 inches of shower and tub, and on all tile substrate surfaces in wet areas; screw spacing maximum 12 inches on center for ceilings 16 inches on center for walls; end butt joints staggered minimum 16 inches; maximum gypsum board moisture content 0.5% by weight before finishing; back-blocking required for unsupported butt joints; PURE KETCHUM — ASTM C840 is a private ASTM International standard, not a California statute, not California administrative code, creating no private civil right of action; ASTM C840 violations generating AHJ inspection failure are recoverable as CLRA actual damages; DISTINCT FROM GA-214 advisory [GA-214 specifies the finish quality taxonomy applied to the face of properly installed and taped gypsum board; ASTM C840 specifies the physical installation requirements for the board itself including fire rating, moisture resistance, fastener spacing, and joint staggering]: the ASTM C840 advisory generates independent documentation: (a) probing the gypsum board surface with a magnet or fastener detector to confirm screw spacing at ceilings and walls; (b) reviewing the AHJ building permit and rough drywall inspection records to determine whether the inspector confirmed fire-rated assembly compliance and moisture-resistant board placement; (c) physically probing behind tile in wet areas to assess gypsum board moisture saturation by measuring flex and softness of the substrate; (d) requesting the building materials receipt or delivery invoice from the unlicensed contractor to confirm whether Type X and MR board were purchased for the project versus standard 1/2-inch board.

D-19 covers limited specialty residential installation, tape and texture, and repair]: Track 1 — UNLICENSED D-19 CONTRACTOR PATCHES 2-HOUR FIRE-RESISTANCE-RATED WALL IN RESIDENTIAL GARAGE AFTER PLUMBING REPAIR USING STANDARD 1/2-INCH DRYWALL INSTEAD OF REQUIRED ASTM C840 / CBC 5/8-INCH TYPE X GYPSUM BOARD → AHJ DRYWALL INSPECTION IDENTIFIES INCORRECT ASSEMBLY → CERTIFICATE OF OCCUPANCY WITHHELD FOR NEW ADU → 9-WEEK DELAY FOR CORRECT TYPE X INSTALLATION → $6,200 REAL ESTATE CLOSING DELAY DAMAGES: ASTM C840 requires 5/8-inch Type X gypsum board for any fire-resistance-rated assembly — including the 2-hour rated garage-to-dwelling separation required by CBC Section 406.3.4 for garages in residential structures; Type X gypsum board achieves its fire-resistance rating through the addition of glass fiber reinforcement and special additives to the gypsum core that prevent the core from calcining and crumbling for the rated period under fire conditions; standard 1/2-inch drywall achieves approximately 20 minutes of fire resistance compared to 60 minutes per layer for 5/8-inch Type X; a 2-hour rated assembly typically requires two layers of 5/8-inch Type X; when an unlicensed D-19 contractor patches a rated assembly after plumbing repair using the wrong board type, the AHJ rough drywall inspection will flag the incorrect material, requiring complete removal and replacement of the patched area with correctly rated board; the Certificate of Occupancy for any associated ADU or addition that includes the garage cannot be issued until the fire separation is verified as correctly constructed; the 9-week delay generates carrying costs, lender rate-lock extension fees ($1,800), temporary housing ($2,400), and real estate agent carrying costs ($2,000) as CLRA actual damages; Track 2 — UNLICENSED D-19 CONTRACTOR INSTALLS STANDARD NON-MOISTURE-RESISTANT DRYWALL IN BATHROOM REMODEL BEHIND NEW TILE SHOWER ENCLOSURE INSTEAD OF REQUIRED ASTM C840 MR GYPSUM BOARD → TILE ADHESIVE ABSORBS MOISTURE THROUGH NON-MR GYPSUM BOARD → GYPSUM CORE SATURATES → TILE INSTALLATION FAILS WITHIN 18 MONTHS → CDPH-CERTIFIED MOLD INSPECTOR IDENTIFIES ELEVATED Stachybotrys chartarum AT WALL CAVITY → $22,400 MOLD REMEDIATION + $14,000 BATHROOM RETILE: ASTM C840 requires moisture-resistant gypsum board on all surfaces to receive ceramic tile in wet areas — standard gypsum board has a paper face that absorbs moisture when the tile adhesive layer experiences moisture infiltration through tile grout; once the paper face absorbs moisture the gypsum core begins to dissolve from the inside; standard gypsum board behind a tile shower typically reaches the structural failure threshold (core crumbling and delamination) within 12–24 months depending on shower usage frequency; Stachybotrys chartarum (black mold) grows specifically on wet cellulose-based materials such as the paper face and gypsum core of water-saturated standard drywall; the mold remediation requires complete removal of the tile, adhesive, and non-MR gypsum board down to the stud framing, HEPA vacuuming and antimicrobial treatment of the stud framing, and installation of a cement board or properly rated moisture-resistant backer board before retiling; Track 3 — UNLICENSED D-19 CONTRACTOR APPLIES LEVEL 3 SKIP-TROWEL FINISH IN NEW CONSTRUCTION HOME FOR SALE WHERE BUYER'S PURCHASE CONTRACT SPECIFIES LEVEL 5 SKIM COAT FINISH FOR PREMIUM GRADE → BUYER DISCOVERS TEXTURE VISIBLE UNDER SATIN PAINT UNDER RAKING LIGHT AT FINAL WALKTHROUGH → DEMAND FOR LEVEL 5 REWORK OF ALL WALLS 4,200 SQ FT → $18,500 DRYWALL FINISH UPGRADE COST → CLRA § 1780 MANDATORY ATTORNEY FEE CLAIM: Level 5 finish requires application of a full skim coat of joint compound or finish plaster over the entire gypsum board surface — not just over the joints and fastener dimples; a Level 3 finish leaves the uncoated gypsum board paper face exposed between joints, which has a subtle paper texture that becomes dramatically visible under satin, semi-gloss, or enamel paint when raking light strikes the surface at a low angle; in premium residential new construction the difference between Level 3 and Level 5 is significant because Level 5 provides the uniform, reflective surface required for luxury paint finishes; retrofitting a Level 5 skim coat over an existing Level 3 finish in an occupied or completed home requires protection of all finished floors, trim, windows, and doors, and the skim coat process generates significant dust requiring complete re-cleaning of the interior — the $18,500 rework cost includes labor, materials, cleaning, and temporary housing for the occupant during the skim coat application and cure period.

Primary Welch Anchor: Tyler Odyssey Civil Complaint Filing Date

The Tyler Odyssey civil complaint filing date is the primary Welch temporal anchor for D-19 dry wall matters. The attorney files after confirming CSLB C-61/D-19 license status, reviewing AHJ building permit and drywall inspection records, inspecting gypsum board type and moisture-resistant placement per ASTM C840, documenting finish level under raking light against GA-214 specifications, retaining a licensed drywall contractor or construction defect expert, and serving the CLRA § 1782 demand. The CSLB D-19/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-19 / C-61 Dry Wall) — THE ONLY D-19 Specialty Anchor in the Fee-Petition-Mechanics Series

The CSLB License Check must confirm the C-61/D-19 Dry Wall limited specialty designation — distinct from C-9 (full specialty covering commercial fire-rated partition engineering, structural steel framing, and exterior sheathing systems). Three scenarios generate § 7028 liability: (a) no CSLB license at all; (b) expired, suspended, or revoked C-61/D-19 license; (c) a general handyman or painter who performs residential drywall installation and finishing as a standalone service without holding the D-19 limited specialty. This page is THE ONLY D-19 Dry Wall specialty anchor in the fee-petition-mechanics series — distinct from C-9.

Billing Gap 1 — CSLB D-19/C-61 License Check, Building Permit and Drywall Inspection Review, GA-214 Finish Level Documentation, ASTM C840 Board Type and Placement Inspection, and § 1782 Demand (5.25 hrs/yr = $1,575–$2,625)

The first billing gap covers pre-complaint advisory for D-19 dry wall matters.

• Searching CSLB License Check for C-61/D-19 designation and establishing the secondary Welch anchor: confirming D-19 limited specialty presence or absence; evaluating C-9 distinction (commercial fire-rated partition systems versus limited residential drywall installation); confirming license status, bond, and workers compensation insurance.
• Reviewing AHJ residential building permit and drywall inspection records — second institutional anchor: obtaining the building permit and rough drywall inspection record for the residential project; confirming whether the inspector reviewed fire-rated assembly compliance and moisture-resistant board placement; reviewing any AHJ correction notices related to drywall type, placement, or fire separation.
• Documenting GA-214 finish level under raking light inspection: systematically inspecting all finished surfaces with a portable work light held parallel to the surface; photographically documenting visible tool marks, tape edges, fastener dimples, and surface texture inconsistency; preparing a room-by-room finish level assessment against GA-214 Level 3, Level 4, and Level 5 criteria.
• Inspecting ASTM C840 board type and placement compliance: confirming gypsum board type (standard, MR, or Type X) at fire-rated assemblies and wet area locations; using a moisture meter to assess saturation level of drywall substrate behind tile; reviewing materials purchase records to confirm board types purchased.
• Serving CLRA § 1782 demand incorporating GA-214 and ASTM C840 advisory analysis: demand specifies D-19 unlicensed contracting, identifies three harm tracks, demands disgorgement under § 7031(b), and specifies CLRA § 1780 mandatory attorney fees.

Billing Gap 2 — Active Litigation: Construction Defect Expert, Mold Inspector, Finish Contractor, and Three-Track Damage Quantification (4.00 hrs/yr = $1,200–$2,000)

The second billing gap covers expert coordination across the three D-19 harm tracks.

• Retaining a licensed contractor or fire protection consultant for Track 1 Type X fire assembly failure: expert confirms ASTM C840 and CBC requirements for 2-hour rated garage-to-dwelling separation; documents the non-compliant 1/2-inch standard drywall installed in place of required 5/8-inch Type X; calculates AHJ correction timeline and real estate transaction delay damages (carrying costs, rate-lock extension, temporary housing).
• Retaining a CDPH-certified mold inspector and remediation contractor for Track 2 non-MR gypsum board mold: mold inspector conducts air quality sampling and surface sampling to document Stachybotrys chartarum levels; building scientist models moisture infiltration timeline from tile grout through non-MR board; remediation contractor quantifies scope and cost of complete tile removal, mold remediation, and retile with properly rated substrate.
• Retaining a licensed drywall finishing contractor for Track 3 GA-214 Level 5 rework: contractor provides a written bid for Level 5 skim coat remediation over all deficient surfaces (4,200 sq ft); documents the GA-214 finish level actually installed through a comparison mock-up under raking light; quantifies occupant displacement and temporary housing costs during skim coat and cure period.
• Settlement valuation incorporating all three harm tracks and CLRA § 1780 mandatory attorney fees: D-19 three-track settlement demand integrates real estate transaction delay damages, mold remediation costs, and finish upgrade costs 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)

The third billing gap covers fee recovery preparation across all three D-19 harm tracks.

• Documenting the CLRA § 1780 lodestar from the CSLB D-19/C-61 License Check date: AHJ building permit and drywall inspection record retrieval; GA-214 raking light inspection photographs and finish level assessment; ASTM C840 board type documentation; fire protection expert opinion on Type X requirement; mold inspector air and surface sample reports; licensed finish contractor Level 5 remediation bid — all fee-petition-eligible.
• Briefing the pure Ketchum multiplier: novelty/difficulty — GA-214 finish level determination methodology (raking light angle selection; photographic documentation protocol; Level 3 vs. Level 5 visual comparison mock-up analysis; critical lighting condition modeling for premium residential real estate); ASTM C840 fire resistance analysis (Type X core chemistry; 5/8-inch vs. 1/2-inch fire endurance comparison; CBC Section 406.3.4 garage separation requirements); mold causation analysis (moisture infiltration timeline through non-MR board; Stachybotrys growth threshold moisture content; OSB versus gypsum board mold susceptibility); Ketchum v. Moses 24 Cal.4th 1122 (2001); PLCM Group Inc. v. Drexler 22 Cal.4th 1084 (2000).
• Missouri v. Jenkins fees-on-fees for the fee petition: Missouri v. Jenkins 491 U.S. 274 (1989); Hensley v. Eckerhart 461 U.S. 424 (1983).
