1. Today's 2:00 PM Appointment Prep — Jullie Williams ("Williams Deck", 12361 W Muir Ridge Dr, Boise ID)

From Val's (Greenbelt Homes) 9:48 AM email today — Reviewer: Cameron Lennon (City of Boise Planning & Development Services, Cycle 1). Every correction below maps directly to a plan note or sheet callout fix:

Ref # Sheet / File Municipality Correction Comment Exact SoftPlan Note / Drawing Fix to Apply at 2:00 PM
Ref #1–2 Site Plan.pdf Site plan setbacks & lot dimensions / property line distances to proposed deck. Add explicit front, rear, and side yard setback dimensions from deck posts/overhang to property lines + Site Plan Standard Note Block.
Ref #3, #5, #9 Summary.pdf
Eng-Details.pdf
Eng-calculations.pdf		 "Update referenced code section to include current adopted codes for the City of Boise." (Flagged in 3 separate places!) Replace Utah code block on Cover Sheet & Engineering Notes with the City of Boise Adopted Code Block (2018 Idaho Residential Code / IRC w/ Boise local amendments, 2018 IECC, 2023 NEC). Copy block below!
Ref #4 Main.pdf (Sheet 2 of 11) "The section view callouts show detail on sheet 2 of 11, this detail isn't provided on sheet 2. Update section view callout or provide detail A on sheet 2 of 11. Update this across all plans to provide consistence and clarity." Update Section Callout bubble on Main.spd so Detail A points to Sheet 6 of 11 (Cross-Section) instead of Sheet 2 of 11, and verify all callout bubbles match actual Plan Set page numbers.
Ref #6 Elevations.pdf "Per City of Boise Design Criteria footing/foundation must be at 24" depth for frost protection. Update for compliance." Ensure all elevation & section footing callouts state: MIN. 24" FROST DEPTH BELOW FINISHED GRADE PER CITY OF BOISE DESIGN CRITERIA (remove any remaining 30" label).
Ref #7 & #14 Main.pdf & General Comment "Provide existing floor plan to show what the original layout of home is and if these are new doors and windows be installed for this project." + "Provide existing floor plan for main and upper floor plan. Provide window and door dimensions." Label all rooms/walls on Main & Upper Floor as (E) EXISTING vs. (N) NEW, turn on window/door dimension labels (e.g., (N) 8'-0" x 8'-0" TEMP. SLIDING GLASS DOOR, (E) 3050 WIN), and add Remodel/Addition Legend Note.
Ref #8 Elevations.pdf "Provide guard rail height and material being used for guard rail per, (R312.1.2)." Add Guardrail Note on Elevations & Section: 36" MIN. GUARDRAIL HEIGHT ABOVE DECK SURFACE PER IRC R312.1.2; METAL/ALUMINUM BALUSTERS SPACED MAX. 4" CLEAR OPENING (4" SPHERE RULE PER R312.1.3); DESIGNED FOR 200 LB CONCENTRATED LOAD.
Ref #10 Plan Review Comment "Provide shear wall engineered plan." Include White Pine Engineering's lateral/shear bracing plan sheet in the combined PDF submittal and add note referencing Structural Shear Wall / Lateral Bracing Sheet.
Ref #11 Eng-calculations.pdf "Provide engineering calculations for footings, foundations and post of deck." Attach Jackson Sagers' (White Pine Engineering) signed deck footing, post, and beam calculation pages (including the approved (3) 1-3/4" x 18" LVL dry-protected beam option or glulam spec).
Ref #12 Cross-section.pdf "Provide drainage information and details for uncovered deck, per (R903.4)." Add Uncovered Deck / Impervious Surface Drainage Note on Cross-Section: UNCOVERED WATERPROOF DECK SURFACE SHALL SLOPE MIN. 1/4" PER FOOT (2%) AWAY FROM STRUCTURE TO EXTERIOR DRAINAGE SCUPPER / GUTTER PER IRC R903.4, WITH CORROSION-RESISTANT METAL FLASHING & COUNTERFLASHING AT WALL INTERSECTION PER R703.4.
Ref #13 Eng-Roof.pdf "Provide glass sliding door and existing header dimension. Provide calculations to show it will adequately support new glass sliding door." Call out exact sliding door rough opening width/height, existing or new header size (e.g., (N) HEADER PER STRUCTURAL CALCS), and add calculation page verifying header load over the new sliding door opening.

2. SoftPlan Code-Review Pass Checklist (Run Before Exporting Any Permit PDF)

Check off these 12 items before exporting a municipal permit set to prevent 95% of Utah & Idaho building department plan-review corrections:

1. Jurisdiction-Matched Code Block & Climatic Table (Cover + Eng): Verify Cover Sheet and Engineering sheets list the exact city/county's adopted IRC/NEC/IECC year and local Frost Depth (e.g., Boise = 24", Utah Valley/SLC = 30", Box Elder/Cache/Mountain = 36"–42"), Ground/Roof Snow Load, Seismic Category, and Wind Speed.
2. Callout & Section Bubble Sheet Cross-References: Verify every Section Cut (`A`, `B`) and Detail Bubble points to the actual sheet number where that section/detail lives in the Plan Set (`Plan Set 1\*.pag`).
3. Remodel / Addition / Deck `(E)` vs. `(N)` Distinction: On any addition, remodel, basement finish, or deck, explicitly show the existing floor plan (`Main` and `Upper`) and label every door and window as `(E) Existing` or `(N) New` with width × height dimensions.
4. Site Plan Completeness & Negative Utility Declaration: Show all 4 property line setbacks, distance between proposed addition/deck and existing structures/garage, driveway width, label all outbuildings, and include an explicit note stating whether well, septic/drain field, or propane tanks exist (or state NONE ON SITE — PUBLIC WATER & SEWER).
5. Guardrail, Handrail & Stair Geometry Note (`IRC R311.7 / R312.1`): Explicitly note guardrail height (`min. 36"`), guardrail material & 4" sphere rule (`R312.1.2–R312.1.3`), stair riser (`max. 7-3/4"`), tread (`min. 10"`), headroom (`6'-8"`), and handrail height (`34"–38"`).
6. Deck / Balcony Drainage & Ledger Flashing (`IRC R903.4 / R507.2`): For any uncovered waterproof deck or covered patio/balcony, call out `1/4" per foot (2%)` drainage slope away from the house, scupper/gutter discharge, and ledger Z-flashing.
7. New Door/Window Header Callouts (`IRC R602.7`): Every new or widened exterior door/sliding glass door or window must label the header size (`(E) Header` or `(N) Engineered Header`) and match the structural calculation sheet.
8. Safety Glazing (`IRC R308.4`) & Egress Windows (`IRC R310`): Label `TEMPERED` on all glazing within 24" of a door arc, within 60" vertically of a tub/shower standing surface, near stairs/landings, or <18" from floor; label `EGRESS` on all sleeping room windows (`5.7 sq ft net clear`).
9. Interconnected Smoke & CO Alarms (`IRC R314 / R315`): Show `SD` in every bedroom + outside sleeping areas + every story, and `CO` outside sleeping areas and on every level with fuel-fired appliances or attached garage.
10. Garage Fire Separation (`IRC R302.5 / R302.6`): Note `1/2" Gypsum Board` on garage walls (`5/8" Type X` on ceilings below habitable rooms), `1-3/8" Solid Wood / Steel OR 20-Min Fire-Rated Self-Closing, Self-Latching Door`, and no HVAC duct penetrations.
11. Electrical AFCI/GFCI/Tamper-Resistant & Ufer Ground (`NEC 210.8 / 210.12 / 250.52`): Include standard NEC electrical code notes on the Electrical sheet so reviewers don't flag missing kitchen island, bath, exterior WP/WR, or concrete-encased electrode specs.
12. Structural Sync Check (Plans vs. Engineering PDF): Confirm footing sizes, frost depth, beam callouts (glulam vs. LVL ply count), and shear wall schedules on architectural sheets match the stamped engineering sheets 100%.
