Every inspection phase from permits to certificate of occupancy — what inspectors look for, the correct sequence, and how to pass the first time.
New construction projects require a series of mandatory inspections that verify each phase of building meets code before the next phase begins. In Los Angeles, these inspections are conducted by LADBS (Los Angeles Department of Building and Safety) inspectors and must be requested through iRFIS or by calling 311.
A typical new construction project requires between 12 and 20 inspections. ADU projects usually require 10–14. The exact number depends on scope, structural complexity, and which trades are involved. Requesting inspections out of sequence results in automatic failure.
All LADBS inspection requests must be submitted by 3:00 PM the day before. Requests can be made up to 3 business days in advance. Miss the cutoff and you lose at least one day.
The first inspection after demolition and site preparation. Verifies that excavation depths and soil conditions meet the approved plans.
Inspects rebar placement, footing dimensions, and anchor bolt positions before concrete is poured. This is a critical hold point — you cannot pour until the inspector approves.
Inspects vapor barrier, reinforcement, and under-slab plumbing before the slab pour. Under-slab plumbing must pass its own inspection first.
The largest single inspection. Verifies all structural framing, shear panels, hold-downs, and connections before walls are closed up.
Inspects supply lines, drainage, venting, and water heater connections while walls are still open.
Inspects wiring runs, box placement, panel installation, and grounding while walls are open.
Inspects ductwork, equipment placement, and refrigerant lines before walls close.
Verifies insulation R-values, air sealing, and energy compliance (Title 24 in California) before drywall.
Inspects drywall attachment before taping and texturing. Verifies nail/screw spacing meets code, especially on fire-rated assemblies.
The final round of inspections verifying all trades are complete, all corrections resolved, and the building is safe for occupancy.
InspectPilot AI maps every inspection in the correct order for your project type, checks trade readiness, and submits requests automatically before the 3 PM deadline. No spreadsheets, no missed deadlines.
Typically 12–20 inspections depending on project scope. ADU projects usually require 10–14. Each must pass in sequence before the next phase begins.
Grading, foundation, slab, framing, rough plumbing/electrical/mechanical, insulation, drywall nailing, then final inspections for each trade before certificate of occupancy.
The inspector issues a correction notice. Fix all items, then request a re-inspection. Failed inspections typically add 2–5 days to the timeline.
No. LADBS requires inspections in the correct sequence. Requesting out of order results in automatic failure. InspectPilot enforces the correct sequence automatically.
