SB 721 vs SB 326: California Balcony Law Compared
Written by RetroCal · ·
Sources: Health & Safety Code §17973 (SB 721) · Civil Code §5551 (SB 326)
California has two separate balcony inspection laws, and property owners often confuse them. The difference comes down to who owns the building. SB 721 covers rental apartments; SB 326 covers condominiums and HOAs. This guide walks through the differences that matter — deadlines, inspector qualifications, scope, and penalties — so you know which law applies to your property and what to do next.
Side-by-side comparison

| First inspection deadline | January 1, 2026 | January 1, 2025 (already passed) |

| Who can inspect | Licensed architect, civil/structural engineer, A/B/C-5 contractor with 5+ years of experience, or certified building inspector | Licensed structural engineer or licensed architect only |
| Minimum sample size | 15% of each type of EEE | A "statistically significant" sample that gives 95% confidence the results represent the whole |

| Report filed with | Retained by the owner; provided to local enforcement on request | Delivered to the HOA board; included in reserve study |

How to tell which one applies
- Rental apartment building, 3 or more units, single owner or LLC: SB 721 applies.
- Condo building governed by an HOA under Davis-Stirling: SB 326 applies — even if some units are rented out.
- Mixed-use building with a residential HOA on top: SB 326 applies to the residential portion.
- Buildings with 2 or fewer units, or detached single-family: neither law applies.
What both laws actually check
Both statutes target the same failure mode: hidden water damage inside wood-framed balconies and walkways that eventually collapse. Inspectors evaluate load-bearing components (joists, ledgers, posts, and their connections), waterproofing (decking membrane, flashing, drip edges), and fasteners. The report classifies findings by severity and recommends whether repairs are advisory, required within a set timeframe, or immediately hazardous.
What happens if you miss the deadline
Under SB 721, a building official who becomes aware of an overdue inspection can issue a notice to the owner stating the response window; local enforcement responses vary by jurisdiction. The $100–$500-per-day civil penalty in Health & Safety Code §17973(i)(2) applies where required repairs remain incomplete after the statute's repair and notice sequence, unless an extension is granted. Under SB 326, the HOA board carries the fiduciary duty — a missed inspection is a compliance gap the reserve study auditor and building department can flag, and any subsequent balcony failure can expose the board to personal liability.
