SB 721 & SB 326: Both Balcony Inspection Deadlines Have Passed—Here's What That Means for Your Property
If you own an apartment building or condo in California with elevated balconies, decks, or walkways, the state now requires you to prove they're safe. As of 2026, the grace period is over.
In June 2015, a fifth-floor apartment balcony in Berkeley collapsed during a birthday party, killing six people and injuring seven. The cause wasn't overcrowding or bad luck—it was dry rot. Years of trapped moisture had quietly destroyed the wood framing behind a waterproofing system that had failed without anyone noticing.
That tragedy is the reason California passed two laws—SB 721 and SB 326—requiring routine inspections of "exterior elevated elements" (EEEs). The goal is simple: catch hidden water damage before it becomes a structural failure. And in 2026, both laws have officially moved out of "deadline approaching" territory and into "deadline passed."
If your inspections aren't done, your property is already out of compliance. Here's exactly where things stand and what you can do about it.
The Two LawsSB 721 vs. SB 326: Which One Applies to You?
Both laws target the same hazard—water intrusion and decay in load-bearing wood elements—but they apply to different property types, with different inspectors, timelines, and re-inspection cycles. Don't assume one covers the other.
| SB 721 | SB 326 | |
|---|---|---|
| Applies to | Apartment & rental buildings with 3+ units | Condominiums & HOA common-interest developments |
| First inspection due | January 1, 2026 (extended one year by AB 2579) |
January 1, 2025 |
| Re-inspection cycle | Every 6 years | Every 9 years |
| Who can inspect | Licensed architect, civil/structural engineer, or qualified contractor | Licensed architect or structural engineer |
| Status in 2026 | Both deadlines have passed | |
The AB 2579 wrinkle
SB 721's original deadline was January 1, 2025—the same as SB 326. A 2024 law, AB 2579, pushed the apartment deadline back one year to January 1, 2026. The condo deadline (SB 326) was not extended. Many owners mixed these up; if you assumed you still had time, double-check which law governs your building.
The ScopeWhat Actually Gets Inspected
Both laws cover "exterior elevated elements"—wood-framed structures that extend more than 6 feet above ground and rely on the building for support. In plain terms:
- Balconies and decks
- Exterior stairways and landings
- Elevated walkways and porches
- The railings, framing, and waterproofing systems that support them
The inspector isn't just looking at the surface. They're evaluating the load-bearing components and the waterproofing that protects them—and that's where most properties fail.
The Real IssueIt's a Waterproofing Problem First
Here's what gets missed: a balcony rarely fails because the structure was built wrong. It fails because the waterproofing system broke down and let water sit against the wood for years. By the time decay is visible from below, the damage is already extensive.
Inspectors are specifically trained to look for the warning signs of a failing waterproof deck:
- Cracked, blistered, or delaminating deck coatings
- Failed flashing, sealants, and transition joints at walls and posts
- Standing water, poor slope, or clogged drainage
- Soft spots, staining, or visible wood rot in framing
- Corroded fasteners and metal connectors
A passing inspection comes down to one thing: keeping water out of the wood. That's why the smartest move isn't just passing the inspection—it's installing a waterproofing system that keeps you compliant for the full 6- or 9-year cycle and beyond.
The StakesWhat Non-Compliance Actually Costs
This isn't a paperwork formality. Skipping or delaying compliance carries real financial and legal exposure:
Insurance carriers are also increasingly requesting proof of compliance at renewal. An expired or missing inspection report can affect your coverage and your premiums. And if an inspector finds an immediate safety threat, they're required to notify local code enforcement—putting you on a tight, non-negotiable repair clock.
Budgeting note
Inspections themselves typically run $500 to $2,000+ depending on property size and how many elements need review. Repairs are separate—and the longer a waterproofing failure goes unaddressed, the more wood you'll be replacing.
Your MoveWhat to Do If You're Behind
If your deadline has passed and your inspection isn't done, the path forward is straightforward:
- Confirm which law applies — apartment (SB 721) or condo/HOA (SB 326).
- Schedule a qualified inspection with the right licensed professional for your property type.
- Address waterproofing failures correctly — repairing the wood without fixing the system that let water in just resets the clock on the same failure.
- Document everything — keep the stamped report, repair records, and product specs for insurance and resale.
The properties that come through this well aren't the ones that scramble to pass a single inspection. They're the ones that treat the deck coating and waterproofing as the long-term asset it is—because the next deadline is already on the calendar.
