If someone has quoted you for an E3 Inspection — a balcony, deck, stairway or walkway inspection — there is one question worth asking before you agree to anything: are they legally permitted to perform it?

California is specific about this, and the rules differ depending on what kind of building you own. An E3 Inspection performed by someone who does not meet the requirement may not satisfy the law — and you, not the inspector, are the one left non-compliant.

This takes about two minutes to check.

What is an E3 Inspection?

E3 stands for Exterior Elevated Elements — balconies, decks, porches, stairways, walkways and entry structures that project beyond the exterior wall, sit more than six feet above the ground, and rely on wood or wood-based products for support.

Two California laws require these elements to be inspected periodically:

  • California Health & Safety Code § 17973 — apartment buildings of three or more units
  • California Civil Code § 5551 — condominiums and common interest developments

A note on “SB 721” and “SB 326”

You will often see these requirements called “SB 721” and “SB 326,” including by companies selling inspections. That is not what they are.

A Senate Bill is a piece of proposed legislation. Once the Legislature passes it and the Governor signs it, the bill is chaptered — its provisions are written into the California codes and the bill itself ceases to be the operative authority. SB 721 and SB 326 were the vehicles in 2018 and 2019. What governs your building today is Health & Safety Code § 17973 or Civil Code § 5551, as since amended.

This is not pedantry. Both statutes have been amended since they were enacted — AB 2579 moved the apartment inspection deadline, among other changes. Anyone still describing the requirement by its 2018 bill number is quoting a document that has been superseded, and may not be working from the current law.

When you compare quotes, notice which citation the inspector uses. It tells you something about how closely they follow the requirement they are charging you to meet.

Step 1 — Which requirement applies to your building?

Three or more apartment units → E3 Inspection for apartment buildings, required by California Health & Safety Code § 17973. In the City of Los Angeles, administered by the Los Angeles Housing Department (LAHD).

A condominium or common interest development → E3 Inspection for condominiums and HOAs, required by California Civil Code § 5551. In Los Angeles, questions go to the Department of Building and Safety (LADBS).

The two are constantly confused, including by some people selling inspections. They carry different deadlines, different inspection cycles, and different rules about who may inspect.

Step 2 — Check the credential against the law

For E3 Inspections of apartment buildings (Health & Safety Code § 17973), the inspection may be performed by:

  • a licensed architect
  • a licensed civil or structural engineer
  • a general contractor holding an “A,” “B,” or “C-5” licence, with at least five years’ experience constructing multistory wood frame buildings
  • an individual certified as a building inspector or building official by a recognised state, national or international association

For E3 Inspections of condominiums and HOAs (Civil Code § 5551), the list is narrower: the inspection must be performed by a licensed structural or civil engineer, or a licensed architect, and the report must be signed by the licensed professional taking responsibility for it. A contractor’s licence alone is not sufficient.

That difference matters. A contractor who may lawfully inspect an apartment building may not be able to deliver a compliant report for a condominium.

Step 3 — The disqualification most owners don’t know about

Health & Safety Code § 17973 states:

“These individuals shall not be employed by the local jurisdiction while performing these inspections.”

The Los Angeles Housing Department says the same in its own published guidance:

“Licensed professional hired by the building owner to perform these inspection cannot be an employee of the City of Los Angeles.”

A building inspector employed by your city cannot perform your E3 Inspection in that city. This is written into the statute — it is not a matter of policy or preference. If someone has offered to inspect your building in a jurisdiction that employs them, the inspection will not satisfy the law.

Step 4 — Verify the number yourself

Ask for the licence or certification number and check it. It takes under a minute:

  • Contractors — California Contractors State License Board licence lookup
  • Architects — California Architects Board
  • Engineers — Board for Professional Engineers, Land Surveyors and Geologists
  • ICC-certified inspectors — International Code Council certification lookup

Confirm the licence is current, that the classification matches the list above, and that the name on the licence is the name that will sign your report.

What to ask before you sign anything

  1. Which requirement applies to my building — the apartment law or the condominium law?
  2. Under which qualifying category are you performing this E3 Inspection?
  3. What is your licence or certification number?
  4. Are you employed by this city in any capacity?
  5. Who signs the report — is that the same person performing the inspection?
  6. When will I receive it? (For apartment buildings, the law requires delivery within 45 days, or 15 days where an immediate hazard is found.)
  7. If repairs are needed, do you have a financial interest in performing them?

An inspector who cannot answer these quickly is telling you something.

Why an E3 Inspection is a specialty inspection

An E3 Inspection is not a general property inspection. It examines load-bearing components and their associated waterproofing systems — the elements whose failure caused the 2015 Berkeley balcony collapse that led to both laws.

The damage is almost never visible from a walkthrough. It is concealed: framing behind finishes, water entering at flashing and membrane terminations, decay progressing for years inside an assembly that looks sound from outside. The law requires inspection of a random, statistically significant sample, and documentation good enough to serve as a baseline when the next E3 Inspection falls due six or nine years later.

An inspection that opened nothing, and a report that documents nothing, is unlikely to be either.

A note on inspection notices

LAHD has published a warning that some private businesses are distributing notices about E3 or balcony inspections that may appear to be official government communications.

If you have received correspondence about an E3 Inspection and are unsure whether it came from the City, contact LAHD directly at 866-557-7368 to verify before responding, providing payment, or supplying personal information.

The E3 Inspection Association is a private membership and certification body. It is not a government agency, and it does not issue notices of violation.
