| 04/02/2015 | RONALD BROWN | BUILDING-COMMERCIAL | REVIEW | Reqs Change | 1. This project is a Change of Use from SFR (IBC R3?) to R-2 Apartments with a mixed use of S-1/S-2 (should probably be called art gallery/work areas) and possibly a SFR space, not yet defined in these documents, that will required certain current 2012 IBC code compliances. As per section 3408 of the 2012 IBC, non- compliance with all the requirements of this code may be permitted provided the new or proposed use is less hazardous, based upon life and fire risk, than the existing use and approval of the building official. a. Please redefine the occupancy classification as a separated, mixed-use of R2, R3 or SFR and S-1 or S-2. Please clarify. Reference section 508 Mixed Use and Occupancy for clarifications and requirements. b. Please provide an allowable building area calculation as per section 508.4.2 showing the sum of the ratios of the actual building areas does not exceed 1. c. As the building has a Certificate of Occupancy issued for a Single Family Residence, please provide a structural analysis of the building showing that it complies with Chapter 16 of the 2012 IBC. d. Provide all accessible requirements as per Section 3411. e. An impact fee assessment is being also considered and the results will be provided to the owner once complete. 2. As per section 1014.2.4 of the 2012 IBC, the means of egress may not pass through a storage room. 3. Provide a listing of Type "A" and/or Type "B" units as required by Section 1107.6.2 of the 2012 IBC and identify each unit shown on the floor plan. a. Include all accessible requirements including clearances. 4. Please provide a existing floor plan. 5. Please show all architecture features of the space located in the far south west corner and define it's use, R2, R3, SFR or something. 6. Please 7. Please reference the 2012 IBC, Section 420 for R2 fire separation and sprinkler requirements. a. The wall legend provided is not very accurate: toilet walls are 2 hr rated, perimeter CMU not identified at all, some stair wells indicated as 2 hour protected and some are not rated. Please identify all fire walls as required by code with a linear symbol and legend. Please show this on a new exiting floor plan. Show all exiting required for this building as per code. 8. Please provide large scale details of all the existing and new stair wells showing all code compliance and accessible requirements as per section 4311. 9. Finish the exterior and interior elevations on sheet A3. 10. Provide compliance with section 1029 for emergency escape and rescue. 11. Provide an occupancy load calculation and show total occupancy. 12. Provide structural calculations for any new roof mounted HVAC equipment and and water heaters either wall mounted or suspended from structural above. END OF REVIEW |

| 04/08/2015 | ROBERT SHERRY | PLUMBING-COMMERCIAL | REVIEW | Reqs Change | 1. The International Plumbing Code, 2012, is the controlling code for this structure, not the International Residential Code.

Note that PVC is not approved for use as a relief pipe; see Table 605.4, IPC 2012 for approved materials. Reference: Section 504, IPC 2012. 12. If the specified water heater is not supplied with integral heat traps, provide heat traps on the supply and discharge piping. Reference: Section C404.4, IECC 2012. 13. If the specified water heater is not supplied with integral heat traps, provide 0.5" of insulation with a maximum conductivity of 0.27 BTU per inch/h F on the first 8 feet of supply and discharge piping. Reference: Section C404.5, IECC 2012. 14. Revise the water pressure calculations to include the pressure drop due to the reduced pressure backflow preventer. Reference: Section 604.1, IPC 2012. 15. For the use of PEX tubing, provide a branch tube sizing chart showing the correct size of PEX tubing to be used as a substitute for the copper pipe shown on the drawings. Reference: Sections 303.2 and 604.3, IPC 2012. 16. Verify that the pipe sizes called out to serve the lofts will not result in water velocities greater than that recommended by the pipe manufacturer (e.g. limit the water velocity to less than 8 FPS for copper, PEX, or CPVC piping). For example, at the water demand for two lofts, 17 GPM, a 1" PEX tube has a flow velocity of 9.5 FPS. Reference: Table 604.3, IPC 2012. 17. Provide water shut off valves for each dwelling unit, accessible within the dwelling unit it serves. Reference: Section 606.1, IPC 2012. 18.
