If you feel that an item is not applicable to your project, note “N/A” and discuss the reason with the plan checker.Please indicate the sheet number and detail to the right of each correction, or note the number on the plans where the correction is made. Resubmit marked original, calculations and this correction sheet. A separate sheet for response may be used.Resubmit corrected sets of plans.Meetings between the project applicant/designer and the plan reviewer shall be by appointment only. Please call (714) 647-5822 for an appointment.
5. The applicant shall obtain clearances/approvals for the following, prior to building permit issuance:
☒Planning Division approval on the corrected/final set of drawings (647-5804). Previously approved plans should be submitted to expedite the process.
☒Public Works Agency approval (647-5039).
☐Fire Department approval on the corrected/final set of drawings (647-5839 or 647-5700).
☒Police Department approval on the corrected/final set of drawings (647-5840).
☒School District Approval; and a copy of the school fee worksheet, completed by the plan check engineer, shall be required by the School District to verify the scope of the work.
☐Proof of Worker's Compensation Insurance shall be required at the time of permit issuance.
☐Grading Permit. Application is made through the Building Safety Division (647-5800) and the plan review is by the Public Works Agency (647-5039).Comments have been provided on drawing and calculation hard copies in relation to all comments below. These may be picked up at Building and Planning department at applicants’ discretion.DrawingsSheet A1
Provide the following design data on the first sheet (R106.1.1)
☐Sheet Index
☒Occupancy groups (R-3/U)
☐Type of construction (V-B)
☐Automatic Fire Sprinkler (YES or NO)
☐Number of stories.
☒Flood Zone: X
☐Flood Zone: A
☐Flood Zone: AE
☐Floor area per occupancy group, including the existing structure(s)
☐Construction shall comply with the 2019 CRC, CBC, CPC, CMC, CEC, California Green Building Code, and California Energy Efficiency Standards Code editions.Sheet A4Provide U-Factor and SHGC in window schedule per T24.Walls separating dwelling units (main house and new ADU) shall be minimum 1-hour fire partition. Fire rated floor-ceiling and wall assemblies shall extend to and be tight against the exterior wall, and wall assemblies shall extend from the foundation to the underside of the roof sheathing. Provide details on the plans. (R302.3 CRC)Walls separating dwelling units shall provide airborne sound insulation for walls with an STC rating of at least 50 per. Provide details on plans and provide verification of a tested assembly to achieve the required STC rating of 50.Sheet A5Provide U-Factor and SHGC in window schedule per T24.Provide elevation change and slope for balcony per Detail 20/SD4.Balconies, decks and exterior stairway exposed to weather and sealed underneath shall be waterproofed and sloped a minimum of ¼” unit vertical in 12 units horizontal (2%) for drainage. Specify manufacturer and ICC report number of waterproofing on the plan.Sheet A6Verify section A/A10 shown on plan.Sheet A10Note on plan: Mechanical, electrical and plumbing are not part of this plan review and approval. MEP are subject to building field inspection.Sheet S1Verify double P2 pad footings in footing schedule.New slab on grade in ADU to be doweled to existing slab.Provide SSW sheets stamped and signed by licensed engineer.Verify if 7’-11” SW spans from ground floor to second floor along Grid C as shown in Sheet S2. Add to foundation plan as needed and provide details. Else if above floor, ensure transfer beam designed with overstrength level seismic forces as required. Sheet S2Verify where Beam B5 between Grids C and Entry Porch extend to. Provide support as needed. Length of beam is longer than designed in calculation, revise calculation with new length. PC #2: Comment not addressed, there is a beam B5 on plan spanning from right side of Entry Porch to existing bathroom. Please verify size as well as support, looks to cantilever past KP with no end support, if so, provide design for single span with cantilevered end.Ensure adequate drag/ shear transfer where required for diaphragm tributary area split shown in calculations. For example, SW 15 and SW 16 on calculation page 9 of 45. If shear line is not extending across entire building but longer than shear wall, adequate drag to transfer load into wall required.Ensure Beam B17 with shearwall above is designed with overstrength level seismic forces as required. PC #2: Please verify deflection adequacy for beam design. Is beam to be cambered as noted in design?Sheet S3Provide RR in area above Grid D.Beam B4 does not match calculation, please revise to match.Verify if 4x8 beam adjacent to Beam B4 on plan is also intended to be revised per previous comment.Verify 2x8 callout above Beam B4 callout on plan.Provide drag at Grid B and Grid 1.5+/- to transfer loads from beyond shearwall length.Verify cantilever shear transfer in area between grid 1A and 1B.Sheet SD1Detail 1 – Verify lag bolt or through bolt between new floor ledger and existing member. CalculationsPage 8 – Provide dimensions on plan or trib area visual to verify trib area calculations provided. Page 9 – Provide dimensions on plan or trib area visual to verify trib area calculations provided.Page 9 – Verify if balcony mass is accounted for in calculations.Page 9 – Provide diaphragm design example for individual diaphragm lengths use for shear wall tributary areas. Page 25 – Beam size does not match drawings. Revise to match. Page 28 – Verify worst case length with plan.PC #2: See comment #14Page 45 – Justify 4.9k load on 12” continuous footing as well as lower loads as needed.PC #2: 4.9k load shown atop interior wall footing at existing bedroom shearwall. Please justify.(End of Comment)
