Code Compliance
Revision 0.3 · Source-currentness recheck: September 30, 2026 · Controlled review checklist
This is a stand-alone change checklist for this trade, added to the existing workmanship and full project-code requirements. It is not a complete trade code manual. It covers reviewed 2016–2026 changes and local implementation events; an older provision newly enforced locally is labeled as implementation, not claimed as newly invented code.

PM
Only affected new, replaced or altered work and legally triggered upgrades are included. The PM selects the applicable legal requirement and the compatible mandatory Anchor overlay before work. Unresolved source, limit or listing conflicts remain HOLD, and N/A requires a written reason. Checking a box means the item and its required evidence passed, not merely that it was read.
Where a city's legal minimum is lower, the compatible higher check remains an Anchor standard unless Cory approves a company-only exception. A city's nonadoption alone is not a reason to mark the higher company check N/A; actual scope, technical compatibility and legal, design or listing conflicts must be resolved.
Existing QR phases: QR-14A.
ST-01
Lath/furring attachment revision
Verify the governing attachment correlation with ASTM C926/C1063 and the accepted system. The reviewed model spacing is 7 in. vertically along studs/furring and horizontally at the stud/furring spacing, subject to adopted and listed requirements.
- Change / applicability
- 2021 IRC R703.7 update. Applies to stucco/lath assemblies.
- Required record
- System/table/detail, measured fastening and pre-plaster photos.
Hold point: Before plaster covers lath.
ST-02
Climate-specific WRB and drainage
Confirm the actual DryB versus MoistA/MarineC conditions and build one complete approved option. Do not export a moist-climate 3/16-in. gap into a dry-climate job as universal law, and do not mix incomplete WRB alternatives.
- Change / applicability
- 2021 climate split; 2024 R703.7.3 scope expanded to all sheathing types. Affects stucco WRB assemblies, including non-wood sheathing under the 2024 rule, subject to its material-damage exception.
- Required record
- Climate and accepted WRB option, material/laps/flashings and drainage photos.
Hold point: Before plaster.
ST-03
Opening flashing/drainage interface
Preserve the accepted opening flashing/drainage path and interior air sealing when installing lath and plaster. Coordinate defects with the WRB and window trades, and do not impose the withdrawn blanket 1–2-in. insulation-stop dimension.
- Change / applicability
- 2021/2024 published R703.4.1 opening detail rechecked; unsupported dimension withdrawn. Affects window/door transitions.
- Required record
- Accepted opening detail and photo evidence.
Hold point: Before closing opening transitions.
ST-04
Silica exposure controls
Use the fully implemented applicable Table 1 equipment/work-practice/respirator route, or an accepted exposure-assessment route. Document a written exposure-control plan and a designated competent person when covered. Do not treat short-duration work as automatically exempt.
- Change / applicability
- 2016 federal construction rule; federal enforcement September 23, 2017; Arizona adoption July 23, 2018. Applies to stucco substrate/grinding, sand-containing cutting and other covered silica tasks. Evaluate exposures from nearby trades as well as your own work.
- Required record
- Task/method, Table 1 entry or exposure assessment, control/respirator evidence, competent person and plan.
Hold point: Before dust-producing work.
ST-05
Weighed construction-waste diversion
Segregate and document eligible lath, plaster and packaging waste toward the project requirement of at least 50% eligible nonhazardous C&D waste diverted by weight. Exclude excavated soil and land-clearing debris, and do not count alternative daily cover or waste-to-energy as diversion.
- Change / applicability
- 2023 Scottsdale mandatory green-code implementation, not a claim the provision first existed in 2023. Applies to the commercial/multifamily green-code scope. Resolve the local < 5,000 sq ft project exception and any higher Anchor requirement.
- Required record
- Weight tickets, material/destination, recycling/reuse receipts and the PM project diversion calculation.
Hold point: Before trade closeout; keep records throughout the work.

Unverified or failed applicable items block the stated hold point. The subcontractor certifies actual work and evidence; the PM independently verifies and releases after required official inspections. Cory approves only company-standard exceptions, never statutory, permit, design or listing waivers.

Applicability Appendix
Record the exact adopted section/amendment, applicable exception, design/product instruction and required test configuration for each item before starting. A model-edition change is not automatically local law, and a local rule exported to another city is an Anchor requirement only when technically compatible and accepted.
This page does not establish an exhaustive all-clause ten-year history or every-city strictness proof. No unverified change is used as a passing criterion; current-only provisions with no demonstrated decade change remain in the full existing acceptance packet rather than falsely appearing here as new changes.
The September 30, 2026 recheck refreshed the cited source evidence. A historical source can verify a change without establishing its current local applicability; a source recheck is not a project release or a complete clause-by-clause supersession certification.
Silica dates distinguish federal enforcement from Arizona's July 23, 2018 adoption reported by ADOSH. Confirm the currently applicable state-plan standard and amendments before issue; the compatible Anchor safety baseline does not waive them. (Arizona adoption notice)
