Multi-Family Balcony Inspection Under California SB-721 and SB-326
Why this matters
California enacted SB-721 (Health and Safety Code 17973) for apartment buildings of three or more units and SB-326 (Civil Code 5551) for condominium associations after the 2015 Berkeley balcony collapse killed six occupants. Both laws require periodic inspection of Exterior Elevated Elements (EEEs) by a licensed professional. A residential deck contractor pivoting to multi-family work must understand the legal trigger, the inspector qualifications, and the report format the local jurisdiction will accept. Performing the wrong scope leaves the building owner non-compliant and exposes the contractor to negligence claims when a collapse later occurs.
Scope of an EEE
Both statutes target the same physical components: balconies, decks, porches, stairways, walkways, and elevated entry structures more than six feet above grade that are supported in whole or substantial part by wood or wood-based products. The waterproof element above is also in scope when its failure would cause concealed decay in the structural framing. Steel-framed assemblies and reinforced concrete balconies fall outside the wood-based trigger but are commonly included on a voluntary basis as part of a building-wide structural condition report.
Who can sign the report
SB-721 (rental apartments) limits inspectors to a licensed architect, licensed civil or structural engineer, certified building inspector, individual certified as a building inspector by a recognized state or national association, or a contractor holding a California A, B, or C-5 license with at least five years of experience constructing multi-story wood-frame buildings. SB-326 (HOA condos) is stricter: only a licensed structural engineer or architect may sign.
Inspection cycle and sample size
SB-721 requires the first inspection by January 1, 2025 and subsequent inspections every six years. SB-326 required completion by January 1, 2025 with re-inspection every nine years. Sample size under SB-721 is a statistically significant random sample sufficient to provide 95 percent confidence that the results reflect the condition of the building's EEEs as a whole. In practice this is interpreted by most jurisdictions as 15 percent of the EEEs at a minimum, with units selected randomly across building elevations and floors.
Report content
The signed report must identify the building, identify each EEE inspected, describe the methods used (visual, moisture meter, endoscope, destructive testing), note the current physical condition of waterproofing and load-bearing components, state the expected future performance and remaining useful life of the EEE, and recommend any further inspection necessary. For SB-721 the report is delivered to the building owner; the owner must keep the prior two reports on the property and must provide the most recent report to the local enforcement agency upon request. Conditions posing an immediate threat to occupant safety trigger a 15-day notice to the local enforcement agency under SB-721.
Destructive vs non-destructive inspection
Pinless moisture meters, infrared thermography, and visual inspection of the ledger flashing termination at the building wall handle most cases. When elevated moisture readings (above 19 percent on a wood substrate per accepted moisture-content thresholds for incipient decay) appear at the ledger or the joist-to-ledger interface, destructive inspection by cutting an access opening in the soffit or interior gypsum is required to confirm or rule out concealed rot. Repair of the opening after inspection is the inspector's responsibility under SB-721 (the statute requires the EEE be left in a "safe and habitable condition").
A finding of immediate threat to safety triggers a written notice to the building owner and, within 15 days, a copy to the local code enforcement agency. Posting the affected EEE as off-limits to occupants is the owner's responsibility but the inspector should photograph the condition before vacating the site.
Documentation deliverable
The acceptable report format varies by city. Los Angeles, San Francisco, Oakland, and Berkeley each publish their own form. At a minimum the report should include the inspector's name, license number, signature, date, address of the building, total EEE count, sampled EEE count and the basis for that sample, photographs of every inspected EEE keyed to a unit-plan diagram, summary table of findings, immediate safety items, and recommended repair scope. Reports must be maintained by the owner for the life of the building.
