City of Los Angeles E3 Inspections & Reporting

Los Angeles Housing Department (LAHD) E3 inspections for apartment buildings citywide.

If a Los Angeles Housing Department routine inspection or notice identifies E3, the property owner must arrange the required inspection with a qualified licensed professional. RetroCal inspects qualifying balconies, walkways, stairs, landings and their structural and waterproofing components, then delivers a clear, photo-documented report that tells you what is safe, what requires repair and what should be monitored.

The January 1, 2026 initial inspection deadline has passed. If your E3 inspection is incomplete or the Los Angeles Housing Department gave you a response or reinspection date, send us that exact deadline so we can evaluate the fastest available schedule.

RetroCal inspection of an exterior apartment walkway, railings and waterproofing transitions on a Los Angeles multifamily building

Did the Los Angeles Housing Department Mark E3 on Your Inspection?

E3 means Exterior Elevated Elements. The Los Angeles Housing Department uses E3 for elevated exterior building components such as balconies, decks, stairways and walkways. A Los Angeles Housing Department item or notice does not replace the inspection required from a privately hired, qualified licensed professional. It tells the owner to address the E3 requirement and document the response by the date shown on the notice.

  • Find the exact response or reinspection date on your Los Angeles Housing Department paperwork.
  • Do not wait to identify every balcony, walkway, stair and landing that may qualify.
  • Submit the property address, building details and deadline in the form below.
  • Upload or send the Los Angeles Housing Department notice if available.

What Is a Los Angeles Housing Department E3 Inspection?

The E3 requirement is a safety inspection for qualifying exterior elevated elements at apartment buildings with three or more multifamily dwelling units. In general, a covered element has a walking surface more than six feet above ground, is designed for people to use and relies in whole or substantial part on wood or wood-based products for structural support or stability.

The purpose is to determine whether the load-bearing components and the waterproofing that protects them are in a generally safe condition, in adequate working order and free from hazardous conditions caused by fungus, deterioration, decay or improper alteration.

Your property may be covered if

  • The building has three or more multifamily dwelling units.
  • It has exterior balconies, decks, porches, stairs, walkways, entry structures or landings more than six feet above ground.
  • Those elements rely in whole or substantial part on wood or wood-based structural support.

Building configuration and ownership type matter. RetroCal can review the property information and help identify the likely inspection scope. This page addresses apartment buildings, not condominium association inspections under SB 326 — see how the apartment and condominium requirements differ.

The RetroCal E3 Inspection Process

A useful E3 inspection is more than a quick balcony walk-through. It begins with a careful inventory, follows the structure and water path, documents the evidence and ends with findings an owner and licensed contractor can actually use.

  1. 1. Review the property and deadline

    We review the address, number of units, available plans or prior reports, known conditions and any Los Angeles Housing Department response or reinspection deadline. We then confirm access and scheduling requirements.

  2. 2. Inventory the E3 types

    The inspector identifies the qualifying types on the property—such as balconies, walkways, stair systems and landings—and records the locations needed for a defensible inspection sample.

  3. 3. Select and inspect the required sample

    California law requires inspection of at least 15% of each E3 type. The inspector evaluates the selected locations and expands the investigation when observed conditions or professional judgment indicate that more information is needed.

  4. 4. Evaluate structure and water protection

    The field review follows load paths, connections and visible structural support while also checking the flashings, membranes, coatings and sealants intended to keep water away from concealed framing.

  5. 5. Use targeted diagnostic instruments

    When appropriate, moisture meters, infrared thermal imaging and borescopes or endoscopes help identify suspect moisture patterns and view otherwise difficult areas. These tools help minimize unnecessary exploratory holes; they do not replace professional judgment or guarantee that a limited opening will never be needed.

  6. 6. Deliver the report and action plan

    RetroCal organizes photos, test results, observations, condition grades and recommended next steps into a signed report. California law requires the written report to be presented to the owner or designated agent within 45 days after completion of the inspection. If repairs are needed, the report is written to support clear pricing and scoping by qualified licensed contractors. Tell us any earlier Los Angeles Housing Department or project deadline before scheduling.

What We Inspect on Balconies, Walkways, Stairs and Landings

Each E3 type behaves differently. Inspector knowledge matters because water entry, structural deterioration and unsafe alterations often begin at transitions, connections and concealed load paths—not only at the most visible surface.

Balconies and decks

The inspector evaluates the visible condition and performance of joists, beams, cantilevered framing, ledgers, posts, supports, connections and fasteners; deck surfaces and drainage; wall and door transitions; flashing, membranes, coatings and sealants; soffits or undersides; and guardrail attachments. The review looks for movement, cracking, staining, soft or damaged materials, corrosion, fungal growth, decay, improper alterations and other evidence of water or structural distress.

Exterior walkways

The inspector follows the walkway's structural support system, including joists, beams, ledgers, posts, connections and attachments to the building. The review also addresses walking-surface condition, slope and drainage, waterproofing and flashing transitions, penetrations, soffits or undersides, guardrail anchorage and visible evidence of leaks, corrosion, decay or deflection.

Exterior stairs

The inspector reviews stringers, treads, risers, landings, posts, beams, attachment points and visible connections, together with handrails and guardrails. Waterproofing or protective coatings, drainage and water-exposed interfaces are checked for conditions that may affect the stair system's safety or service life.

Landings and entry structures

The inspector evaluates the load-bearing framing and supports, connection to the building, walking surface, edge and guard conditions, drainage, flashings, membranes, coatings, sealants and transitions at doors, walls and stair interfaces. Particular attention is paid to trapped water and locations where a small waterproofing failure can damage concealed framing.

The exact scope depends on the property, the selected statutory sample, access, observed conditions and the inspector's professional judgment.

The Inspector's Knowledge Becomes the Quality of Your Report

An E3 report should not leave an owner guessing. The inspector must understand how the element carries weight, how water is supposed to drain, where waterproofing commonly fails, how corrosion or decay presents and which observed condition is merely maintenance versus a condition that requires corrective work.

RetroCal reports connect each finding to a specific building, E3 type and location. Photos are captioned. Test results are explained. The narrative states what was observed, why it matters and what action is recommended. That level of detail makes the report easier for the owner to understand and gives qualified licensed contractors a clearer basis for preparing comparable repair quotes.

Clear enough for an owner. Detailed enough for a contractor.

A Descriptive Grading Rubric—Not a Vague Punch List

RetroCal clearly separates safety hazards, required repairs, recommended work, cosmetic monitor items and components in excellent condition so the owner can prioritize decisions without treating every observation as the same level of concern.

  • 1 — Immediate Hazard: Action Now

    A condition the inspector determines presents an immediate threat to occupant safety or requires immediate access restriction, shoring or emergency repair. The report clearly identifies the location, observed evidence and immediate protective recommendation.

  • 2 — Repair Required: Non-Emergency Corrective Work

    A condition that requires repair or replacement but is not classified as an immediate threat at the time of inspection. The report identifies the affected component, explains the concern and recommends an appropriate repair direction so permit and contractor scoping can begin.

  • 3 — Recommended Work: Not Required, but Advised

    A condition that is not classified as a required repair but where work is recommended to protect the component and avoid future deterioration. The report explains the observation and the recommended work so the owner can decide on timing and budget.

  • 4 — Cosmetic: Monitor

    A cosmetic or minor condition with no repair requirement. The report establishes what to watch and why, creating a useful baseline for routine maintenance and ongoing property care.

  • 5 — Excellent: No Work Required

    The inspected component is documented in excellent condition at the time of inspection, with no work required. Photos and notes preserve a clear baseline for the owner's property records.

The rubric is RetroCal's reporting and communication system; it does not replace the inspector's signed professional findings or the requirements of the Los Angeles Housing Department, the permitting authority or California law.

High-Tech Evaluation With Fewer Unnecessary Openings

Exploratory demolition can disturb tenants, damage finishes and add cost before the condition is understood. RetroCal uses advanced diagnostic instruments where appropriate to gather more information with less disruption.

Moisture meters

Help identify elevated moisture readings at suspect surfaces and transitions.

Infrared thermal imaging

Helps screen for temperature patterns that may support a moisture investigation when site conditions allow.

Borescopes and endoscopes

Can provide targeted views through existing gaps or very small access points when conditions permit.

Our goal is to avoid unnecessary exploratory holes and openings as much as possible. If concealed conditions cannot be evaluated reliably with visual and non-invasive methods, the inspector may recommend a limited opening or further investigation. The report will explain why.

A Better Report Produces Better Repair Quotes

When repair findings are vague, contractors are forced to make assumptions. That leads to inconsistent scopes, hard-to-compare bids and costly change orders. A detailed RetroCal report identifies the location, component, observed condition, severity and recommended repair direction. Owners can use that information to request quotes from qualified licensed contractors on a clearer, more consistent scope.

  1. E3 inspection
  2. clear finding
  3. repair recommendation
  4. contractor quotes
  5. permits and repairs when required
  6. repair verification and final documentation

You are free to choose the qualified licensed contractor who performs the repairs. RetroCal can also provide repair, waterproofing, guardrail and permit-coordination services through its licensed contracting operation, but there is no obligation to hire RetroCal for repair work after the inspection.

If the E3 Report Identifies Repairs

Immediate safety condition

Follow the inspector's immediate protective directions. These may include preventing access, shoring or emergency repair. Applicable emergency findings are reported to the owner and local enforcement agency on the timeline required by law.

Non-emergency repair condition

Begin permit and contractor planning promptly. California law generally requires the permit application within 120 days after receipt of the report and completion within 120 days after permit approval, unless the local enforcement agency grants an extension.

After required work is completed, the inspector can re-evaluate the repaired locations and, when requested, prepare final documentation indicating that the required repairs have been completed. If your initial inspection is already late, see how to bring an overdue inspection current.
