California SB 326 Balcony Law: What Condo Buyers Must Know

California's SB 326 requires condo balcony inspections every 9 years. The first deadline passed January 1, 2025. Inspections are revealing widespread structural problems, triggering special assessments of $40,000 to $175,000 per unit.

You're buying a condo in California. The HOA fees look reasonable. The reserve study shows decent funding. Then you learn the building hasn't completed its SB 326 balcony inspection. Or worse, it has, and the results are bad.

Across the state, condo associations are discovering that balconies, walkways, and stairways have been quietly deteriorating for years. One inspection company reported that a large share of inspected balconies needed some level of repair. Per-balcony repair costs run $10,000 to $25,000 according to industry estimates. Full reconstruction in high-cost markets can reach $40,000 to $60,000 per unit. One California HOA attorney has seen assessments as high as $175,000 per unit.

If you're buying a California condo, SB 326 compliance is no longer optional due diligence. It's the difference between a sound investment and a six-figure surprise.

What Is SB 326?

SB 326 requires California condos to inspect balconies and exterior walkways every 9 years. The first deadline was January 1, 2025.

SB 326, codified as California Civil Code Section 5551, was signed into law in 2019. It requires condominium associations with three or more multifamily units to inspect all exterior elevated elements (EEEs): balconies, decks, stairways, walkways, and railings that extend beyond the building's exterior walls, sit more than six feet above ground, and are supported by wood or wood-based products.

The law exists because of the 2015 Berkeley balcony collapse. On June 16, 2015, a fifth-floor balcony at the Library Gardens apartment complex sheared off during a birthday party, killing six people and injuring seven others. The building was only eight years old. Investigators found that dry rot from improper waterproofing had destroyed the wooden support beams. The contractor had used untreated lumber without adequate waterproof membrane protection.

Under SB 326, inspections must be performed by a licensed structural engineer, architect, or civil engineer (civil engineers were added by AB 2114 in July 2024). The inspector must use a statistically significant sample providing 95% confidence with a margin of error no greater than 5%. If an immediate safety threat is found, the HOA must block occupant access, and the inspector must report to local code enforcement within 15 days.

SB 326 vs SB 721: Condos vs Apartments

SB 326 covers condos. SB 721 covers apartments. The condo deadline already passed. The apartment deadline was extended to 2026.

California has two separate balcony inspection laws. SB 721 (2018) covers landlord-owned apartment buildings under Health & Safety Code Section 17973. SB 326 (2019) covers HOA-governed condominiums under Civil Code Section 5551. Many condo boards mistakenly believe that AB 2579, which extended SB 721's apartment deadline to January 1, 2026, also extended their deadline. It did not. HOAs that missed January 1, 2025 are currently noncompliant.

SB 326's sampling standard is more rigorous. Where SB 721 requires inspecting a flat 15% of each element type, SB 326 demands a statistically significant sample. In practice, this often means inspecting a larger percentage of balconies, especially in smaller buildings.

The Reserve Study Connection

SB 326 inspection results must be incorporated into the HOA's reserve study. If the reserve study predates the inspection, it is legally incomplete.

This is where SB 326 directly affects your purchase decision. Civil Code Section 5551(f) requires the stamped inspection report to be incorporated into the association's reserve study under Section 5550. That means repair costs identified during the SB 326 inspection become line items in the reserve funding plan.

If the HOA completed its inspection but hasn't updated the reserve study, the study is missing a legally required component. If the HOA hasn't completed the inspection at all, the reserve study has a blind spot on structural condition. Either way, the percent funded ratio you see may not reflect reality.

SB 410 (2025) further clarified that SB 326 inspection reports are part of the HOA reserve study disclosures that must be provided to buyers. You have a legal right to see the results.

What Happens When Problems Are Found

Inspections are revealing widespread damage. Costs range from $10,000 per balcony for repairs to $175,000 per unit in the worst cases.

The results coming back from SB 326 inspections are not encouraging. Industry professionals report that the majority of inspected balconies have needed some level of repair. Individual balcony repairs typically run $10,000 to $25,000 according to industry estimates. Full reconstruction in markets like San Francisco and the Peninsula can reach $40,000 to $60,000 per unit.

Jeff Beaumont, an HOA attorney at Beaumont Tashjian, told Mortgage Grader he has seen special assessments as high as $175,000 per unit. Beach communities face even higher repair costs due to salt air accelerating corrosion, with assessments reaching $100,000 per unit.

One 96-unit coastal condo built in 1999 discovered elevated moisture in 22% of its balconies during an infrared scan. Engineers found hidden ledger rot beneath the surface. The HOA secured a $1.2 million loan at 6.3% over 10 years to fund repairs.

The financial cascade doesn't stop at repair costs. Insurance carriers are increasingly requiring proof of SB 326 compliance before renewing master policies. HOA attorney Jeff Beaumont has reported seeing insurance premiums increase by 100% to 400% in affected buildings. Lenders are beginning to ask for SB 326 certification as part of due diligence. At least one lender has classified routine repair recommendations as "critical repairs", refusing to finance a pending sale.

What Buyers Should Check Before Closing

Ask five questions about SB 326 compliance before writing an offer on any California condo.

These questions apply to any California condo with three or more units and wood-framed exterior elements. Don't assume the seller or listing agent will volunteer this information.

• Has the SB 326 inspection been completed? The deadline was January 1, 2025. If the HOA hasn't done it, they're noncompliant and you have no visibility into structural condition.
• What were the findings? Request the full stamped engineer or architect report. Under SB 410 (2025), this is part of the reserve study disclosures the HOA must provide.
• Has the reserve study been updated to reflect SB 326 costs? Civil Code 5551(f) requires it. If the reserve study predates the inspection, it's missing a legally required component.
• Are there any pending or planned special assessments? Repair costs from SB 326 findings often trigger assessments. Check whether one has been levied, is being planned, or could follow from the inspection report.
• What is the building's insurance status? Ask for the current master policy carrier, coverage amount, and recent premium history. Non-compliance or unresolved structural issues can lead to coverage gaps that affect loan eligibility.

If you're evaluating multiple properties, these five data points separate buildings that have addressed their structural obligations from those that are sitting on unknown risk. The SB 326 report, combined with an HOA document review, gives you the clearest picture of what you're actually buying into.
