See Table M1507.3.3(1) for continuous whole house mechanical ventilation system <br /> airflow rate requirements. <br /> 2. The locations of all smoke and CO alarms should be shown on the floor plans on Sheet A2.2. A <br /> note should be included on the plans specifying that alarms should be hardwired, <br /> interconnected, and provided with back-up battery power as required per IRC Sections R314 <br /> and R315. <br /> 3. The project appears to include modifications to the stairs. Details for the construction should <br /> be included. The stringers should comply with the joist span tables considering the net depth <br /> after notching for steps. The stair rise and run, and width, should be specified. Handrails <br /> should be provided. See IRC Section R311.7. <br /> 4. Guard details should be included in the construction drawings. The guards should comply with <br /> IRC Section R312.1. The guards, connections to the supporting framing, and the supporting <br /> framing should be designed to resist a minimum 200-pound load per Table R301.5. <br /> 5. See skylight windows.
