SB 721 Balcony Inspections: Every Apartment Owner's Deadline and Action Plan

Published March 10, 2026

SB 721 requires balcony inspections for buildings with 3+ units. The initial deadline was January 1, 2025. Here's your complete action plan.

If you own an apartment building in California with three or more units, SB 721 applies to you, and the initial inspection deadline has already passed. If you have not completed your inspection yet, you are technically out of compliance as of January 1, 2025. You can still get compliant, but stop waiting.

Let me break down what this law actually requires and what it costs in practice.

Why This Law Exists

SB 721 is a direct response to the 2015 balcony collapse in Berkeley that killed six people and injured seven others. The balcony was attached to an apartment building and had severe dry rot in the wood framing that no one had identified. That tragedy led the legislature to mandate inspections of exterior elevated elements on apartment buildings statewide.

Wood framed balconies, walkways, and stairways deteriorate over time, especially in coastal areas where moisture exposure is constant. In the South Bay, I have seen buildings that looked perfectly fine from the street but had structural framing that was compromised enough to be dangerous.

What SB 721 Requires

The law applies to buildings with three or more dwelling units that have exterior elevated elements (balconies, decks, walkways, stairways, and their railings) that are wood framed and more than six feet above grade.

"Wood framed" includes any structural component made of wood. If your building has concrete or steel balconies, SB 721 does not apply to those elements, though you may still want to inspect them for your own liability protection.

The initial inspection deadline was January 1, 2025. After that, inspections are required every six years. So if you completed your inspection in 2024, your next one is due by 2030.

Inspection reports must be submitted to the local enforcement agency, which is typically the city building department. The report needs to identify any issues found and categorize them by severity.

Who Can Perform the Inspection

Not just anyone can do an SB 721 inspection. The law requires that inspections be conducted by a licensed architect, a licensed structural engineer, or a licensed general contractor (Class A, B, or C) with at least five years of experience.

In my experience, hiring a structural engineer is worth the slightly higher cost because their reports carry more weight if you ever face a liability claim, and they are better equipped to identify subtle deterioration that a general contractor might miss.

Make sure whoever you hire provides a written report that meets the statutory requirements. A one paragraph letter saying "everything looks fine" is not sufficient.

What It Actually Costs

Inspection costs vary based on building size and the number of elevated elements, but here are real numbers from buildings we manage.

A 20 unit building in Torrance with 16 balconies and two exterior walkways: $6,800 for the inspection and report. A 36 unit building in Hawthorne with 30 balconies, four walkways, and two exterior stairways: $14,200.

That is real money, but repairs cost far more when problems turn up, and a structural failure costs far more than that.

When Problems Are Found

On one building we manage, the inspector found dry rot in the structural framing of six balconies. The wood looked fine on the surface, but moisture had been penetrating through failed waterproofing membranes for years. The repair estimate came in at $127,000 for structural remediation, new waterproofing, and replacement of the affected framing members.

The owner was understandably frustrated by the cost. Those balconies were being used daily by tenants. If one had failed, the liability exposure would have been in the millions, not to mention the human cost. $127,000 in preventive repairs is a fraction of what a single injury lawsuit would cost.

When the inspection identifies emergency conditions, the inspector is required to notify the building owner and the local enforcement agency immediately. The owner must restrict access to the affected elements and begin repairs without delay.

Penalties for Non Compliance

If you do not complete your inspection, the local enforcement agency can impose civil penalties. The amounts vary by jurisdiction, but they are typically structured to escalate over time. More importantly, the agency can order that tenants be prohibited from using the elevated elements until inspections and any necessary repairs are complete.

Beyond regulatory penalties, the liability exposure is significant. If an uninspected balcony or walkway fails and someone is injured, the fact that you did not comply with SB 721 will be Exhibit A in the lawsuit.

SB 326 vs SB 721

There is a related law, SB 326, that applies to condominiums and HOA governed buildings. The requirements are similar but not identical. SB 326 requires inspections by a licensed architect or structural engineer (contractors are not eligible under SB 326), and the inspection standards are slightly different.

If you own rental apartments, SB 721 is your law. If you own a condo or sit on an HOA board, SB 326 is the one to follow. Some buildings may be subject to both depending on their structure and ownership.

Your Action Plan

If you have not completed your SB 721 inspection, here is what to do right now.

First, identify all exterior elevated elements on your building that are wood framed and more than six feet above grade. Walk the property and make a list.

Second, hire a licensed structural engineer or qualified contractor. Get at least two quotes, but do not choose solely based on price. The quality of the inspection report matters.

Third, schedule the inspection as soon as possible. Many inspectors are still working through backlogs, so lead times of four to eight weeks are common.

Fourth, once you receive the report, review it with your property manager or attorney. If repairs are needed, get estimates promptly and prioritize anything the inspector flagged as urgent.

Fifth, submit the completed report to your local building department. Keep copies of everything.
