Mr. Ismail Mohammad 2713 Maple Street, LLC Plan Check Number: B2101-051, First Building Review May 3, 2021 a. Aerial imagery of the project site appears to indicate that the actual distance between the exterior building walls for the two buildings is less than 10 feet. The distance should be verified and revised as needed. b. The project should specify an imaginary lot line between the two building to establish the effective fire separation distances for each building. Note that the distance should not be less than 5 feet for the single-family residence (SFR) (i.e., the western building) unless improvements to this building are performed under a separate permit. See IBC Section 705.3. The distance between the exterior building and the existing Single-Family residence has been updated on Sheet Al Site Plan to reflect 9'-7". An imaginary lot line has been added to Sheet Al Site Plan between buildings, the Single-Family Residence existing porch will be adjusted to provide 5'from the imaginary property line to the existing building. 7. The building has a 0-foot fire separation distance on the north side and a presume fire separation distance of less than 10 feet on the west side. These sides of the buildings are required to have a minimum one-hour fire-rated construction per IBC Table 602. The walls are required to be rated from both directions per IBC Section 705.5. Details for the walls including references to rated tested assemblies should be provided. See IBC Section 703.2. The existing north wall will be 1hr rated, reference and details have been provided per IRC on sheet A4 Sections. The west wall will have a 5' separation from the imaginary lot line and a total of 10' from the existing Single-Family Residence once the existing covered porch has been adjusted. 8. Continuing with the previous comment, the parapet on the north wall is required to have the same construction as the wall below. See IBC Section 705.11.1. The existing parapet on the north wall will be 1 hr rated, note has been added to wall section C on sheet A4 Sections. 9. The west wall includes unprotected openings. The distance between two buildings appears to be less than 10 feet. Presuming a minimum 5-foot fire separation distance is provided for the SFR, this will result is a fire separation distance of less than 5 feet for the multi-family building. The maximum allowable area of unprotected openings should be determined. See IBC Table 705.8. An imaginary lot line has been added to Sheet Al Site Plan between buildings, the Single-Family Residence existing porch will be adjusted to provide 5'from the imaginary property line to the existing building therefore having a total of 10' between buildings. 10.The"Wood-Framed Wall"detail on Sheet 5 is not consistent with the specified UL listings. In addition, the detail does not provide the stated STC rating of 50-54. A revised listing or revised detail should be provided. See IBC Sections 420.2, 703.2, 708, and 1207.2.
