Southern California Retail Shell: 62 Issues Found

Summary: The note states, '4. HABITABLE ROOMS SHALL BE PROVIDED WITH NATURAL LIGHT OR ARTIFICIAL LIGHTING CAPABLE OF A MINIMUM OF 6 FOOT-CANDLES MEASURED 30\' ABOVE FLOOR LEVEL.' LABC 1205.3 states, '1205.3 Artificial light. Artificial light shall be provided that is adequate to provide an average illumination of 10 footcan- dles (107 lux) over the area...

Why it matters: If the design follows this note, room lighting can be underdesigned, which can trigger plan-check comments, failed inspection, and fixture revisions.

Suggested next step: Revise the note to require artificial light to provide an average illumination of 10 footcandles at 30 inches above the floor level, and confirm the lighting design is not based on the 6 foot-candle value.

RFI draft: Revise the note to require artificial light to provide an average illumination of 10 footcandles at 30 inches above the floor level, and confirm the lighting design is not based on the 6 foot-candle value.

Summary: General Note E.5 states that slabs on grade may have 'A 4\' GRAVEL BASE OR VAPOR BARRIER.' LABC Section 1907.1 requires a slab-on-grade vapor retarder: 'A 6-mil (0.006 inch; 0.15 mm) polyethylene vapor retarder ... shall be placed between the base course or subgrade and the concrete floor slab, or other approved equivalent methods or materials...

Why it matters: If this note is used for permitting or construction, slab-on-grade work could be approved or installed without the vapor-retarding layer required by Section 1907.1, leading to a code correction and possible slab rework.

Suggested next step: Please revise General Note E.5 so slab-on-grade construction requires the Section 1907.1 '6-mil (0.006 inch; 0.15 mm) polyethylene vapor retarder' or another 'approved equivalent methods or materials' to retard vapor transmission through the floor slab, and remove the '4\' GRAVEL BASE OR VAPOR BARRIER' option unless a code-compliant equivalent...

RFI draft: Please revise General Note E.5 so slab-on-grade construction requires the Section 1907.1 '6-mil (0.006 inch; 0.15 mm) polyethylene vapor retarder' or another 'approved equivalent methods or materials' to retard vapor transmission through the floor slab, and remove the '4\' GRAVEL BASE OR VAPOR...

Summary: Security note 1a states that the affected swinging doors shall be 'equipped with a latch and a deadbolt' and only makes the latch a dead latch when it has a key-locking feature. Section 6709.2 requires these doors to be equipped with 'a deadbolt and deadlocking latch,' so the note permits a less secure latch condition than the code.

Why it matters: If exterior door hardware is selected from this note, the project can procure noncompliant entry hardware and fail security review or field inspection, forcing hardware substitution after ordering or installation.

Suggested next step: Revise Security Requirement 1a to require a deadbolt and deadlocking latch in accordance with Section 6709.2, and coordinate the corrected requirement with the door hardware schedule.

RFI draft: Revise Security Requirement 1a to require a deadbolt and deadlocking latch in accordance with Section 6709.2, and coordinate the corrected requirement with the door hardware schedule.

Summary: The sheet includes 'FIGURE 14 – STANDOFF PIN CONFIGURATION FOR SINGLE ROW INSTALLATION (IRC ONLY)¹,²,³,⁴.' On the same approval package, the Los Angeles supplement states, '2.1 LABC: The Base Rail and Talon guardrail systems, described in Sections 2.0 through 7.0 of the evaluation report ESR-4799, comply with the LABC Chapter 24' and '• The...

Why it matters: This can delay plan approval and procurement because the submitted glass guard basis of approval does not match the allowed Los Angeles Building Code use. If left uncorrected, the guardrail system may need to be replaced with an approved Base Rail or Talon system, or the team will need a different approved/engineered compliance path.

Suggested next step: Please confirm whether the proposed glass guard is a Universal Standoff Pin system. If so, provide an approval path permitted for LABC, or revise the design to a system covered by the Los Angeles supplement, which states that the Base Rail and Talon systems comply with LABC and that the Universal Standoff Pin system is limited to LARC...

RFI draft: Please confirm whether the proposed glass guard is a Universal Standoff Pin system. If so, provide an approval path permitted for LABC, or revise the design to a system covered by the Los Angeles supplement, which states that the Base Rail and Talon systems comply with LABC and that the...

Summary: The sheet includes 'FIGURE 13 — TYPICAL TREAD INSTALLATION' and states, 'Note: This connection is outside of the scope of this report.' Another report page states, '• Under the LARC, an engineered design in accordance with LARC Section R301.1.3 must be submitted for attachment methods not covered in the evaluation report ESR-4797.' LABC Section...

Why it matters: This creates an approval gap for the tread connection because the report page itself says the connection is outside scope. That will likely require separate engineering or an alternate approved report before the connection can be accepted during plan review or construction.

Suggested next step: Provide the approval basis for the tread-installation connection shown in Figure 13. Submit either a report/listing that includes this connection within scope or a project-specific engineered detail and calculations for the tread attachment.

RFI draft: Provide the approval basis for the tread-installation connection shown in Figure 13. Submit either a report/listing that includes this connection within scope or a project-specific engineered detail and calculations for the tread attachment.

Summary: The sheet includes “FIGURE 13 — TYPICAL TREAD INSTALLATION” and immediately states “Note: This connection is outside of the scope of this report.” Another page on the same sheet states that “an engineered design ... must be submitted for attachment methods not covered in the evaluation report ESR-4797.” Under LABC Sections 1703.4.1 and...

Why it matters: If this out-of-scope tread connection is intended for construction, plan review or deferred-submittal approval can be held up until a separate engineered detail and supporting documentation are provided. Fabrication may also need revision if a different, report-covered tread connection is required.

Suggested next step: Provide a separately engineered detail and supporting calculations for the Figure 13 tread connection, or revise the stair system to a tread connection that is within the scope of the submitted report and clearly identify the governing approved detail.

RFI draft: Provide a separately engineered detail and supporting calculations for the Figure 13 tread connection, or revise the stair system to a tread connection that is within the scope of the submitted report and clearly identify the governing approved detail.

Summary: In the 'STEEL STUD/BRICK VENEER – WINDOW HEAD DETAIL,' the assembly note reads 'WATER RESISTIVE BARRIER ( IF USED )', which makes the water-resistive barrier optional. Section 1404.2 requires a continuous water-resistive barrier behind the exterior wall veneer, and Section 1403.2 requires the exterior wall envelope to prevent the accumulation...

Why it matters: If this detail is used as drawn, the exterior wall could be built without the required water-resistive barrier at the window head, creating a noncompliant wall envelope and increasing the likelihood of water intrusion and corrective rework.

Suggested next step: Revise the steel stud/brick veneer window head detail so the water-resistive barrier is mandatory rather than optional, and show the continuous WRB/flashing transition at the window head in compliance with Sections 1403.2 and 1404.2.

RFI draft: Revise the steel stud/brick veneer window head detail so the water-resistive barrier is mandatory rather than optional, and show the continuous WRB/flashing transition at the window head in compliance with Sections 1403.2 and 1404.2.

Summary: The stair section and elevation depict open risers: individual treads are shown on sloped stringers with open spaces between adjacent treads. Chapter 11B requires stairs to comply with Section 11B-504, and Section 11B-504.3 does not permit open risers.

Why it matters: If the stair is fabricated as shown, it will not comply with Chapter 11B and will require redesign or reconstruction before approval and use.

Suggested next step: Revise the stair details and elevations to provide closed risers at both stair runs and update the stair assembly accordingly.

RFI draft: Revise the stair details and elevations to provide closed risers at both stair runs and update the stair assembly accordingly.

Summary: The stair general notes direct compliance with Florida code references rather than the governing California building standards. The drawing states 'STAIR TO COMPLY WITH THE FOLLOWING ( S.F.B.C. 31033 TABLE 31-B)' and also cites '( FBC. 2020 CH-23)' for the stair live-load basis. The California code states that only the standards effective for...

Why it matters: If this note remains, plan review, shop-drawing review, and stair fabrication can proceed using nonapplicable Florida criteria for the stair design basis shown on the sheet, creating permit comments and potential rework before construction can proceed.

Suggested next step: Please revise the stair general notes to remove the 'S.F.B.C.' and 'FBC. 2020' references and reissue the sheet with the governing California code citations and stair design criteria that apply to this project.

RFI draft: Please revise the stair general notes to remove the 'S.F.B.C.' and 'FBC. 2020' references and reissue the sheet with the governing California code citations and stair design criteria that apply to this project.

Summary: Elevation A shows a large bank of upper cabinets above a countertop, and Elevation C shows an upper cabinet or shelf unit over a lower base cabinet with a countertop. The drawing dimensions show a '3'-0\'' counter height and a '2'-6 1/2\'' dimension above that counter to the upper storage condition, placing the lowest upper storage at 5'-6...

Why it matters: If built as detailed, the pantry will include storage that is not reachable within the code range, which can trigger accessibility corrections and require casework redesign after fabrication.

Suggested next step: Revise the pantry casework so storage intended for accessible use is located within the Section 11B-308 reach range, or provide a compliant accessible storage arrangement in lieu of the shown upper cabinets/shelves.

RFI draft: Revise the pantry casework so storage intended for accessible use is located within the Section 11B-308 reach range, or provide a compliant accessible storage arrangement in lieu of the shown upper cabinets/shelves.

Summary: General Note 15 states 'MOISTURE-RESISTANT GYP. BD. @ ALL BATHROOM C.L.G.' Note 11 on the same sheet separately includes 'WALL AND CEILING PANELS IN SHOWER AREAS' within the wet-area substrate requirements. LABC 2508.2 states that gypsum wallboard shall not be used where there will be direct exposure to water or continuous high humidity...

Why it matters: If this note is not corrected, shower-area ceilings could be built with moisture-resistant gypsum board and then require correction after inspection, affecting wet-area finishes and related rework.

Suggested next step: Revise Note 15 to exclude shower ceilings and state the code-compliant ceiling substrate for shower areas so the bathroom ceiling notes are consistent with LABC 2508.2.

RFI draft: Revise Note 15 to exclude shower ceilings and state the code-compliant ceiling substrate for shower areas so the bathroom ceiling notes are consistent with LABC 2508.2.

Summary: The SPRINKLER DETAIL shows a 'PIPE Ø3/4\'' passing through a 'SLEEVE Ø4\'' in a '7/8\' STUCCO OVER / METAL LATH & BLD'G / PAPER WHERE OCCURS' exterior wall assembly, and the graphic depicts the smaller pipe centered inside the larger sleeve through the wall. No sealant, flashing, or other weather-sealed closure is indicated at the penetration....

Why it matters: Because the detail shows the pipe and sleeve but does not depict how the opening is sealed to the stucco/building paper wall assembly, the installation intent and inspection criteria at this penetration are unclear, increasing the risk of water intrusion and field rework.

Suggested next step: Revise the sprinkler wall penetration detail to show the required weather-sealed/flashed penetration condition integrated with the building paper/WRB and stucco system, and clarify how the 'SLEEVE Ø4\'' around the 'PIPE Ø3/4\'' is closed/sealed at the exterior wall.

RFI draft: Revise the sprinkler wall penetration detail to show the required weather-sealed/flashed penetration condition integrated with the building paper/WRB and stucco system, and clarify how the 'SLEEVE Ø4\'' around the 'PIPE Ø3/4\'' is closed/sealed at the exterior wall.

Summary: Door types ID A and ID E are listed as 'TYP RES UNIT INTERIOR' with a 2'-8' door panel width. Both also reference the same 'B/ A7.03 D/ A7.03 B/ A7.03' head/jamb/sill detail set used by ID B, which is explicitly noted as a 'REGULAR DOOR.' ID E is not a regular door as originally stated; it is noted as 'CUSTOM DOOR, TOUCH LATCH SYSTEM TO MATCH...

Why it matters: Because these are scheduled residential unit interior door types, this noncompliance can repeat at multiple unit locations and lead to accessibility corrections, door/frame replacement, and rework across many openings.

Suggested next step: Revise door types ID A and ID E to a compliant door configuration that provides a 32-inch minimum net clear opening at 90 degrees for interior user-passage doors, and update all affected unit plans, schedules, and referenced details.

RFI draft: Revise door types ID A and ID E to a compliant door configuration that provides a 32-inch minimum net clear opening at 90 degrees for interior user-passage doors, and update all affected unit plans, schedules, and referenced details.

Summary: A2.21 explicitly says to 'REFER TO SCHEDULE A8.03' and its fixture legend defines 'F4. RECESS MOUNTED DOWN LIGHT FIXTURE.' On the referenced lighting fixture schedule, F4 is listed as 'F4 | CLOSETS | CEILING MOUNTED.' Those are different mounting types for the same fixture tag.

Why it matters: If this is not corrected, the contractor could rough in and cut the ceiling for a recessed fixture while procurement and installation are based on a ceiling-mounted closet fixture. That can cause incorrect product ordering, ceiling rework, and field coordination delays.

Suggested next step: Please confirm whether fixture tag F4 is intended to be a recessed down light or a ceiling-mounted closet fixture, and revise either the A2.21 fixture legend or the A8.03 lighting fixture schedule so the F4 designation is consistent.

RFI draft: Please confirm whether fixture tag F4 is intended to be a recessed down light or a ceiling-mounted closet fixture, and revise either the A2.21 fixture legend or the A8.03 lighting fixture schedule so the F4 designation is consistent.

Summary: The garage floor is shown with different elevation notation in the two drawings. One location shows the garage at '-7 1/2\'', while the other shows '0'-7 1/2\''. Those values do not match because one is negative and the other is not.

Why it matters: An incorrect garage elevation can affect the slab step, door thresholds, drainage direction, and adjacent foundation and framing heights. This should be resolved before construction so the garage-to-house level change is built correctly.

Suggested next step: Please confirm the correct garage finish floor elevation and revise the garage room tag or the garage datum so both drawings show the same signed elevation.

RFI draft: Please confirm the correct garage finish floor elevation and revise the garage room tag or the garage datum so both drawings show the same signed elevation.
