TI drawings LADBS plan checkers accept on the first submittal are the exception, not the rule. Most packages don’t get kicked back because the scope is wrong, they get kicked back because the drawing package is incomplete, internally inconsistent, or missing a required document. They get kicked back because the drawing package is incomplete, internally inconsistent, or missing a required document that the plan checker won’t overlook. A tenant improvement permit in Los Angeles is not just a set of floor plans. It’s a coordinated package of architectural sheets, structural and MEP drawings, support forms, code analysis, energy compliance documents, and signatures, all formatted to LADBS standards and delivered through the right channel. At As-Built Drawings Los Angeles, we’ve prepared TI drawing sets for retail tenants, restaurant operators, and office clients across the city, and the same gaps come up on first submittals again and again. This article covers exactly what to include, which forms and fees to budget for, how to submit through ePlanLA, and what code areas to address before you file.
TI Drawings LADBS Package: What Must Be Included
The drawing package is the core of your submittal. Before anything else gets reviewed, a plan checker evaluates whether the set is complete, legible, drawn to scale, and formatted to LADBS standards. Every sheet must be a minimum of 24″ x 36″, fully dimensioned, and clear enough to verify code compliance without guesswork. Knowing what belongs in the set before your designer starts production prevents the common experience of discovering missing sheets after you’ve already paid the plan-check fee.
Architectural and Site Plan Sheets LADBS Requires
The architectural portion of a TI plan set must include a plot plan showing the site context, a floor plan of the tenant space at the current and proposed layout, a roof plan, exterior elevations, and cross-sections through key conditions. Disabled access features must also be documented, which means showing accessible routes, restroom compliance, door clearances, and signage locations in sufficient detail for CBC Chapter 11B review. The plot plan is not optional even for interior TI work; LADBS uses it to verify setbacks, site configuration, and context. Treat every sheet as something a plan checker unfamiliar with the project will need to read on its own.
An index of drawings is also required by law and must be included on the cover sheet or first sheet of the set. Every sheet referenced in the index must actually be in the package when you upload. A single missing sheet reference is enough to trigger a correction round before any technical review even begins.
Structural, MEP, and Green Building Plans
If the TI scope includes any structural work, you need a foundation plan, floor framing plan, and structural framing and connection details. This applies to wall relocations, new openings, framing modifications, and any change that affects the load path of the building. Structural plans must be stamped and signed by a California-licensed structural engineer or architect of record.
MEP sheets, covering mechanical, electrical, and plumbing systems, are required whenever those systems are being altered, extended, or installed new. This is the section most designers underestimate when the scope feels light on paper. Even a modest office TI that adds a break room can trigger plumbing review, HVAC modifications, and electrical load calculations. Green building plans are required when the scope triggers California Green Building Code provisions, which can happen with larger renovation scopes or specific system changes.
Supporting Documents, Forms, and Fees Your LADBS TI Application Needs
The drawing set is only part of the application. LADBS also requires a layer of supporting documents, signed calculations, and permit forms that travel alongside the plans. Many applicants prepare a thorough drawing set and then stumble at plan check because the supporting documents are missing or don’t match the drawings. Getting this layer right before you submit is just as important as the plans themselves.
Core Forms and Supporting Documents
The main LADBS Building Permit Application is required for every submittal. Depending on your scope, you’ll also need supplemental trade forms for electrical, mechanical, or plumbing work. If the TI affects lighting, HVAC, or other regulated equipment, Title 24 energy compliance forms are required and must match the equipment schedules shown on the drawings. Structural calculations for vertical and lateral loads, signed by a California-licensed engineer or architect, must accompany any set that includes structural sheets. Material specifications, building records such as prior permits and Certificates of Occupancy, and any site-specific hazard documentation (soils report, methane report) are also on the LADBS required list depending on the project location and scope. If the Owner-Builder Declaration applies because no licensed contractor is filing, that form must be included as well.
Who Signs the Plans, Who Pays, and What to Budget for Fees
Every architectural and structural sheet must carry the stamp and wet or digital signature of a California-licensed architect or engineer. This is not a detail to sort out after the plans are drawn. If an expeditor or agent is filing on behalf of the owner or contractor, a notarized authorization letter may be required. The contractor’s license information must appear on the permit application, and LADBS requires clear identification of who will sign for and pay for the permit at issuance.
For fees, LADBS calculates permit charges based on project valuation, with additional per-section review fees and surcharges that include a Development Services Center surcharge and a Systems surcharge applied to the total. For a commercial TI, fees can add up quickly across multiple review disciplines. Budget for plan check fees, trade permit fees, and any correction-related resubmittal costs, and treat the initial fee payment as a deposit against total approval costs rather than the final amount.
How to Submit TI Plans Through ePlanLA
LADBS handles TI permit submittals electronically through ePlanLA for most commercial projects, and the platform covers the full process from initial upload through permit issuance. Understanding the ePlanLA TI submittal workflow before you file prevents delays caused by incorrect routing or incomplete uploads. Choosing the right plan-check path up front is where the timeline is really set.
Choosing the Right Plan-Check Path for Your Project
LADBS offers three main paths for TI plan check. Counter or over-the-counter review is available for simple, eligible scopes and can be completed in roughly 45 to 60 minutes at a Development Services Center. Expanded Counter review handles medium-complexity work and typically runs about two hours. Regular Plan Check is the path for larger or more complex TI projects and generally takes 8 to 16 weeks depending on the completeness of the package, the number of correction rounds, and any required agency coordination. Most commercial TI projects land in Regular Plan Check, and the timeline from submittal to permit is directly tied to how complete the package is at first submission. A single correction round can add weeks to the schedule, which matters significantly when you’re working against a lease commencement date.
The ePlanLA Upload Workflow, Step by Step
The ePlanLA submission process follows a clear sequence. Work through these steps before your target submittal date to avoid scrambling at the portal:
- Create or access your MyLADBS or Angeleno account to reach LADBS online services.
- Start your plan-check application in ePlanLA and enter the project information accurately.
- Upload the complete plan set and all supporting documents as properly formatted PDFs.
- Pay the initial plan-check fees through the portal when prompted.
- Monitor the application for plan-check comments from the reviewer.
- Prepare revised sheets and a written response letter keyed to each comment number, then upload the correction package through the same portal.
- After approval, complete any remaining fee payment and download the permit and stamped plans electronically.
- Schedule inspections as required by the scope and request a final inspection when the work is complete.
The most common ePlanLA stumble is uploading an incomplete package because supporting documents were prepared separately from the plans and not consolidated before submission. Confirm that every required document listed in the application is in the upload before you hit submit.
Code Areas LADBS Scrutinizes Most in TI Plan Checks
A commercial TI plan check is not a single review. It’s a parallel review across multiple code disciplines, and each discipline has its own checklist. Understanding which areas get the most scrutiny helps you design and document the project correctly before the LADBS plan check for TI work begins, rather than reacting to corrections after the fact.
Egress, Accessibility, and Fire Life-Safety Review
CBC Chapter 10 governs means of egress, and LADBS reviews exit paths, occupant load calculations, door swing and operation, travel distances, and exit widths on every commercial TI. These are high-frequency correction areas because tenant layouts sometimes prioritize aesthetics over egress geometry. CBC Chapter 11B accessibility requirements and ADA path-of-travel obligations are reviewed separately and frequently generate corrections when a TI triggers upgrade requirements that aren’t addressed in the drawings. LAFD handles a separate Fire Life Safety Plan Check covering fire protection systems, fire-resistive assemblies, and life-safety provisions. If your TI affects sprinkler coverage, fire alarm devices, or rated assemblies, LAFD review is part of the overall approval process and adds coordination time. Address these disciplines in the design phase, not as an afterthought after plan check begins.
MEP Scope, Energy Compliance, and Structural Alterations
Mechanical, electrical, and plumbing systems each route through separate trade review at LADBS. HVAC and ventilation changes require duct routing plans, equipment data, ventilation calculations, and seismic bracing details. Electrical alterations require load calculations, panel schedules, and documentation of AFCI and grounding requirements. Plumbing fixture changes need fixture counts, waste and vent routing, and coordination with the floor plan. Title 24 energy compliance is a recurring correction trigger when equipment or lighting changes aren’t fully documented with the required compliance forms. Even a TI scope that looks minor on the surface, relocating a few partition walls, for example, can simultaneously touch structural, mechanical, electrical, and accessibility review. Understanding that early in the design process keeps the drawing set organized by discipline and prevents omissions at submittal.
How to Avoid Correction Cycles Before You File
Correction cycles are costly: they push back your schedule and inflate your project budget. Most first-round corrections are not caused by design errors. They’re caused by coordination failures between disciplines, inconsistent information across sheets and forms, and missing documentation that could have been caught in a pre-submittal review. Treating the submittal like a coordinated package rather than a collection of separate deliverables is the mindset shift that makes the difference.
The Most Common Correction Triggers and How to Prevent Them
Missing or mismatched project data is the most common and most avoidable correction. If the project address, owner name, occupancy classification, or scope description doesn’t match between the permit application, the plans, and the supporting forms, the plan checker flags it immediately. Verify every data field across every document before upload. Missing dimensions or unclear details on wall sections, framing conditions, or elevation references generate corrections because the plan checker can’t confirm code compliance without explicit information shown on the sheet. Zoning and setback information must be fully dimensioned on the site plan, including lot coverage, height, and parking compliance where applicable. Structural calculation omissions, incomplete MEP documentation, missing Title 24 forms, and fire and accessibility gaps each represent a discipline that didn’t get fully coordinated before submittal. For each one, the prevention is the same: bring the discipline into the drawing set completely, not as an afterthought.
Running a Pre-Submittal Check Across All Sheet Types
Before uploading anything to ePlanLA, run a coordination check across architectural, structural, MEP, and zoning sheets. Confirm that room names, occupancy classifications, equipment schedules, and project data match across every sheet and every form. Look specifically for mismatches between the floor plan and the MEP sheets, between the structural calculations and the framing plan, and between the Title 24 compliance forms and the equipment schedules shown in the drawings. These cross-discipline mismatches are the fastest way to generate a correction round. If corrections do come back after submittal, respond with a written letter that addresses each comment by number, clearly marks all revised content on the resubmitted sheets with revision clouds, and explains what changed and why. Vague resubmittals that don’t directly respond to each comment invite a second round of corrections.
Getting a Permit-Ready TI Drawings LADBS Package Without the Back-and-Forth
Preparing a complete, LADBS-compliant set of TI drawings requires current knowledge of submittal requirements, the ability to coordinate across multiple code disciplines, and direct familiarity with how LADBS plan checkers evaluate specific project types across Los Angeles County. That’s not something you can fully replicate from a checklist alone, especially when lease timelines are tight and correction rounds push back your opening date.
