• 40 Mr. Martin Reimers Concept Architecture, LLC Plan Check Number: B2202-036, First Building Review May 2, 2022 General 1. The proposed construction includes creating a habitable basement per Basement Plan 1/A2.1. Building Section 1/A4.1 appears to indicate a clear height of at least 7 feet. However, real estate photos of this level appear to show a reduced height. A minimum uniform height of 6 feet 8 inches is allowed for existing basements per IPMC-18 Section 404.3 Exception 2. This should be confirmed and shown in the drawings. Note that use of the habitable space is limited to laundry, study, and recreation areas; the bathroom will also be allowed at this height. Architectural 1. Wall Section 4/A4.1 shows a minimum clearance at the top of the stairs of less than 6 feet 8 inches. The clearance should be increased. See Section R311.7.2. 2. Landings should be specified in the Main Level Plan 2/A2.1 at each end of all exterior stairs. See Section R311.7.6. 3. The basement requires an emergency egress exit, which may be satisfied by the route through the storage room. The doors for this route are required to comply with R310.1.1. The drawings should specify that keyed locks are prohibited in the direction of travel. 4. The basement stairs in the Basement Plan 1/A2.1 requires guards on each side and a handrail on at least one side. See Sections R311.7.8 and R312.1. 5. The bedrooms in the Second Plan 3/A2.1 require emergency egress openings. It appears that the house has existing windows that are not shown in the plan that will qualify. If the existing windows do not qualify, then the new windows are required to provide compliant emergency egress openings. See Section R310. 6. The Second Plan 3/A2.1 indicates that the walls are constructed using 2x4 framing with R-21 insulation. A non-batt type insulation should be specified. See WSEC-18 Table RA101.4. 7. The Basement Plan 1/A2.1 indicates that the furring walls are constructed using 2x4 framing with R-21 insulation. The following comments should be addressed: a. The Wall Legend should specify a gab between the wood framing and the concrete wall. Alternatively, preservative-treated or naturally-durable wood should be specified. In either case, the bottom sill plates should be preservative-treated or naturally-durable wood. See Section R317.1. b. A non-batt type insulation should be specified. Alternatively, the framing should be gapped to allow installation of R-21 batt insulation without compression. The minimum gap size should be specified. See WSEC-18 Table RA101.4. 8. The interior basement door between the new habitable space and unconditioned storage room should have a maximum thermal rating of 0.28 per the Energy Notes on A2.1. See WSEC-18 Section R402.1.
