California SB-721 And SB-326 Balcony Inspection Program

Why this matters

California's two balcony-inspection statutes - SB-721 (rental, three or more units) and SB-326 (HOA condominiums) - require periodic inspection of Exterior Elevated Elements (EEEs) including decks, balconies, walkways, and stairways more than 6 ft above grade with a substantially wood structural support. The statutes have specific inspector qualifications, inspection scopes, reporting timelines, and remediation enforcement that differ from a normal residential deck inspection. Deck contractors working in California either become the qualified inspector under SB-721 (Section 17973 of the Health and Safety Code) or take on the repair work that follows an inspection report, and both paths require knowing the statute mechanics cold. This reference covers what triggers the inspection, who can perform it, what gets inspected, the report-and-cure timeline, and the documentation the building official expects.

Statutory scope

SB-721 (Health and Safety Code Section 17973) covers buildings with three or more multifamily dwelling units and rental occupancies. It applies to all Exterior Elevated Elements where the walking surface is more than 6 ft above grade and the structural support contains substantial wood members. The first inspection was due by January 1, 2025; recurring inspections are required every 6 years thereafter.

SB-326 (Civil Code Section 5551) covers HOA condominiums. It applies to the same EEE definition. The first inspection was due by January 1, 2025; recurring inspections are required every 9 years thereafter.

Both statutes target the same structural concern - the load-path failure that killed six tenants at the Library Gardens balcony collapse in Berkeley in 2015 - but they sit in different code books and have different inspector qualifications.

Qualified inspector

SB-721 inspections may be performed by:

• A licensed architect.
• A licensed civil or structural engineer.
• A general contractor (license class A, B, or C-5) with at least five years of experience in constructing multi-story wood-frame buildings.
• A certified building inspector or commercial building inspector under an ICC certification scheme.

A C-5 framing contractor with the experience qualification can perform SB-721 inspections; a C-13 fencing contractor or a C-39 roofing contractor cannot. The statute spells out the qualifying classes.

SB-326 inspections may be performed only by a licensed architect or a licensed structural engineer. The C-5-contractor path that SB-721 allows is not available for HOA condominium inspections - HOAs must hire an architect or SE.

Scope of inspection

The inspection covers load-bearing components and associated waterproofing of the EEE. The published scope includes:

• Joists, ledgers, beams, posts at the EEE.
• Connections of those members to the building (ledger bolt pattern, lateral-load tension ties per IRC R507.9.2).
• Waterproofing membrane condition where it exists (most multifamily balconies have a sheet or liquid-applied membrane under the deck surface).
• Visible signs of dry rot, fungal growth, water intrusion, corrosion of fasteners.
• Guardrail and handrail attachment to the EEE.

SB-721 requires inspection of at least 15 percent of each type of EEE in the building. SB-326 requires inspection of a "statistically significant sample" per the inspector's judgment - typically 5 to 15 percent for HOA programs.

The inspection method is non-destructive where possible (visual and probe) but the inspector is authorized to require destructive opening (removing a section of stucco, soffit, or decking) where non-destructive inspection cannot confirm condition. The cost of destructive opening and patching is generally an owner cost, not the inspector's.

Inspection report and the cure timeline

SB-721 inspector must deliver a written report within 45 days of inspection to the property owner. The report identifies any defect that "poses an immediate threat to the safety of the occupants" - and that finding triggers a specific cure sequence:

• Owner must apply for a building permit to make repairs within 120 days of receipt of the report.
• Owner must complete the repairs within 120 days after permit issuance.
• If repairs are not completed in that window, the local building official is required to take corrective action, which may include posting the balcony or unit as uninhabitable.

A defect that does not pose immediate threat must still be addressed within a "reasonable timeframe" per the statute, typically interpreted as within the next inspection cycle (6 years for SB-721).

SB-326 reports go to the HOA board, and the board must take action consistent with the report. The HOA's reserves study and assessment authority cover the cost.

What the deck contractor sees on the repair side

Typical SB-721/SB-326 reports identify one or more of these conditions:

• Ledger attachment non-compliant with R507.9 (lag screws into a single rim ply, no lateral-load tension tie).
• Rim joist rot behind the ledger, found by destructive opening or by visible water staining on the soffit below.
• Joist-end rot at the building face, behind a damaged or missing waterproofing detail.
• Guardrail attachment with no engineered uplift or lateral connection - common on older balconies where the rail is bolted through stucco into nothing structural.
• Corroded fasteners (often electroplated where stainless or hot-dip galvanized was required for a coastal site).

The repair work must be permitted, performed under the inspector's recommended scope, and the inspector or owner must sign off on completion. Photos of the cure work go in the property's EEE file, retained by the owner for two inspection cycles per SB-721.

Inspector documentation

The inspector's report must include:

• Address, building description, EEE types and locations inspected.
• Method of inspection (visual, probe, destructive opening).
• Photographs of the conditions observed.
• Findings, including the immediate-threat determination if applicable.
• Recommended repair scope and timeframe.
• Inspector signature, license number, date.

The report is a public record once filed with the local enforcement agency, and a defective EEE that is not cured in the statutory window can be the basis for a tort claim by an injured occupant against the owner. Inspectors carry professional liability insurance for this reason.
