5. The drawings should clearly delineate between existing and new work using established drafting standards. All demolition should be shown on the existing floor plans. All new construction should be shown on the new floor plan. Where the proposed project includes modifications existing building components (e.g., gypsum wall board, insulation, etc.), these components should be similarly delineated from existing component that are not being altered. See IRC Section R106.1.1. 6. The scope of work appears to be incomplete. Based on an electrical inspection performed on 10/28/2021, modifications to the house may include but are not limited to modifying walls, doors, floors, roof, windows, sinks, showers, and toilets. All proposed work should be clearly shown in the drawings. See Section R106.1.1. Architectural: 7. New and modified bedrooms should have emergency egress openings. The minimum opening dimensions and area, and maximum bottom sill opening height of the floor, should be specified. See IRC Section R310. 8. Smoke and CO alarms should be provided per IRC Sections R314 and R315. The locations of all alarms should be shown on the plans. A note should be included requiring the alarms to be hardwired, interconnected, and provided with back-up battery power as required. Alarm clearances should comply with Section R314.3 Item 4 and Section R314.3.1. 9. Insulation should be specified for all modifications to the exterior walls, floors, slab-on-grade, and ceiling/roof cavities per WSEC Table 402.1.1. Structural: 10. The proposed project includes structural work. Structural drawing should be submitted that include framing and foundation plans, sections, details, construction schedules, fastening schedules, materials requirements, general notes, special inspection requirements, etc. The drawings should substantiate compliance with the prescriptive requirements of the IRC. See IRC Sections R106.1.1 and R301.1. 11. The modified load paths should comply with the prescriptive limitations of the IRC. Alternatively, an engineered analysis and design may be performed per IRC Section R301.1.3; sealed and signed drawings and calculations prepared by a professional engineer licensed in the state of Washington are required per RCW 18.43.010, 18.43.020, and 18.43.070. See IRC Section R301.1. 12. The proposed project includes the demolition of non-bearing walls. Framing plans for the floor, ceiling, and roof should be provided to substantiate that the walls are not load-bearing. The plans should also include a note requiring the contractor to verify the walls are not load bearing prior to demolition. See IRC Section R301.1. 13. Details for the construction of the new walls should be included. The details should specify connections for the top and bottom framing plates to the existing structure. See IRC Sections R106.1.1 and R301.1. 14. The proposed design includes modifications to the existing wall bracing that may not comply with the requirement of IRC Section R602.10. the locations and extents of modified braced wall lines should be 2 J J
