The SB 721 Deadline Has Passed. Here's What That Means for Your Property.

If you own or manage a multifamily rental property in California and haven't completed your SB 721 inspection yet, this post is for you.

The SB 721 deadline passed on January 1, 2026. That was already an extension — the original deadline was January 1, 2025, and AB 2579 gave property owners one additional year. That runway is gone. Properties without completed inspections are now in non-compliance, and the consequences are real.

Here's what you need to know.

What Is SB 721?

SB 721, also known as California's Balcony Inspection Law, was signed in 2018 following the 2015 Berkeley balcony collapse that killed six people. It requires owners of multifamily rental buildings with three or more units to have their exterior elevated elements (EEEs) inspected by a qualified professional on a six-year cycle.

Exterior elevated elements include balconies, decks, walkways, stairways, landings, and railings that sit more than six feet above ground and rely on wood framing for support.

The law applies to apartment buildings and multifamily rentals. Condominiums fall under a separate law, SB 326, which had its own deadline of January 1, 2025.

What Happens Now That the SB 721 Deadline Has Passed?

Missing the deadline doesn't mean you're automatically fined. But it does mean your exposure has changed significantly.

Here's what non-compliance looks like in practice:

Properties without an inspection on file have no documentation to show regulators, insurers, or courts if something goes wrong. If a structural failure occurs and you have no inspection record, your legal and financial exposure is substantially worse than if you had engaged a qualified inspector and begun addressing findings.

Daily fines of $100 to $500 can be imposed for properties where issues are identified and not resolved within statutory timelines. The clock starts running once a hazard is found — and you can't find a hazard until you've done the inspection.

Insurance carriers are increasingly requesting compliance documentation at renewal. Properties without it may face coverage complications.

The bottom line: the longer you wait, the more exposure you carry.

Who Does SB 721 Apply To?

Your property falls under SB 721 if it meets all of the following:

• Located in California

• Three or more rental dwelling units

• Has balconies, decks, stairs, walkways, or other elevated elements supported by wood framing

• Those elements sit more than six feet above ground

Single-family rentals, duplexes, and detached structures are not covered. Condominiums and HOA-governed properties fall under SB 326, not SB 721.

What the Inspection Actually Requires

SB 721 requires inspection of at least 15% of each type of exterior elevated element on the property. The inspection must be performed by a qualified professional — a licensed architect, licensed civil or structural engineer, licensed general contractor with at least five years of relevant experience in multistory wood-frame construction, or a certified building inspector.

The inspector cannot be the same person who performs the repairs. That's by design — the law requires an independent assessment.

Once the inspection is complete, findings fall into one of two categories:

Immediate hazards must be reported to the local building department right away. The owner is then required to restrict access to the affected element and obtain a permit for repairs.

Non-emergency findings give the owner 120 days to apply for a repair permit. The completion deadline is set by the inspector and local enforcement agency based on severity.

After repairs are completed, the next inspection cycle runs six years out — January 1, 2032.

What SB 721 Repairs Actually Involve

Most SB 721 repairs address three things: damaged wood framing, failed waterproofing, and corroded connectors. These three issues almost always appear together because they share the same root cause — water intrusion over time.

Replacing framing without addressing waterproofing means the new framing will rot the same way the old framing did. A complete repair addresses all three.

At Diamond Pro, we've completed SB 721 repair work across multifamily properties throughout Southern California. The scope varies by property — some repairs are contained to a single balcony, others involve multiple buildings and dozens of elements. What doesn't vary is the sequence: proper removal, framing repair or replacement, waterproofing system installation, and final inspection sign-off.

If You Haven't Started Yet, Here's Where to Begin

Step one is the inspection. Contact a qualified inspector — an independent one, not one affiliated with a contractor — and get the assessment scheduled. Inspector availability is real, so don't assume you can book next week.

Step two is understanding your findings. Once you have the report, categorize what requires immediate action versus what falls into the 120-day repair window.

Step three is selecting a contractor. Get multiple bids, verify licensing, and make sure the scope addresses framing, waterproofing, and hardware together — not just the visible damage.

If you're managing multiple properties, prioritize by risk: older buildings, coastal exposure, and buildings with visible signs of water damage at elevated elements should go first.
