If you manage or own a multi-unit residential property in California, staying compliant with SB 721 and SB 326 isn’t optional—it’s the law. These state mandates require routine inspections of decks, balconies, and elevated walkways to ensure structural integrity and resident safety.
Failing to meet these inspection deadlines doesn’t just pose legal risks—it puts lives in danger.
In this guide, we’ll break down the importance of deck inspections, what they involve, how often they’re required, and why working with a licensed professional can save you serious time, money, and liability.
Why Deck Inspections Are Necessary
As a property owner, your primary responsibility is to ensure that your structures are safe, code-compliant, and well-maintained. Deck inspections aren’t just a preventive measure—they’re now legally required under Health and Safety Code 17973 aka SB 721 (for apartments) and CA Health and Safety Code CA5551 aka SB 326 (for condos and HOAs) in California.
Prevent Structural Failures
Exterior Elevated Elements (EEEs) like decks and balconies are exposed to weather, moisture, and daily wear and tear. Over time, wood rot, corrosion, and stress due to moisture intrusion into unintended areas can cause these structures to weaken or collapse—especially in multi-story buildings.
Ensure Safety for Residents
Deck inspections help identify hazards like loose railings, rotting joists, and unstable staircases before they become safety concerns.
Identify Hidden Damage
Some of the most dangerous issues with decks are hidden from view. A professional inspection uncovers concealed water damage, insect infestations, and failing structural connections.
Maintain Compliance with Building Codes
In California, compliance with Senate Bill 721 and Senate Bill 326 is now mandatory for qualifying properties. These laws mandate routine inspections by qualified professionals to protect residents and mitigate legal risks.
Extend the Lifespan of Your Deck
Routine inspections and proactive repairs help prolong the structural life of your deck or balcony—delaying the need for costly rebuilds.
Increase Property Value
A well-maintained, code-compliant deck is a key selling point for buyers and tenants. It shows that the property is cared for and structurally sound.
Does Your Property Require a Deck Inspection Under SB 721 or SB 326?
If you own or manage a multi-unit residential property in California, your building may fall under mandatory inspection laws—regardless of whether visible damage is present. Here’s how to know if you’re legally required to schedule a professional inspection:
You must comply with SB 721 (CA Health and Safety Code 17973) if:
- Your property is an apartment building with three or more units
- Your building includes exterior elevated elements (EEEs) such as decks, balconies, stairways, or walkways that:
- Are six feet or more above ground
- Are load bearing components in part or in total constructed of wood or wood-based materials
- Are accessible to tenants or maintenance staff
- Are six feet or more above ground
You must comply with SB 326 if:
- Your property is a condominium building governed by a Homeowners Association (HOA)
- Your building features EEEs that:
- Meet the same criteria as above (6+ feet high, wood-supported)
- Are exclusive use areas accessible by residents
- Meet the same criteria as above (6+ feet high, wood-supported)
Important Deadlines:
- SB 721: First inspection was due by January 1, 2025 and subsequently amended to January 1 2026 (repeat every 6 years)
- SB 326: First inspection was due by January 1, 2025 (repeat every 9 years)
If you’re unsure whether your property qualifies under these laws, a licensed inspection company can evaluate your building and guide you through compliance.
What a Professional Deck Inspection Covers
A professional deck inspection—especially one designed for SB 721 and SB 326 compliance—is far more than a casual walk-through. It’s a systematic evaluation of the entire deck structure, focusing on safety, code compliance, and longevity.
1. Foundation and Support Posts
Check for visual evidence of movement, erosion, cracks, or water damage affecting stability.
2. Deck Boards and Surface
Look for splintering, warping, loose boards, and decay.
3. Ledger Board and Fasteners
Verify the deck’s attachment to the structure is secure and free from rot or rust.
4. Railings and Balusters
Ensure railings are stable and connections are sound.
5. Stairs and Stringers
Inspect treads, risers, and stringers for wear, looseness, or damage.
6. Joists and Beams
Evaluate for sagging, separation, or compromised structural integrity.
7. Mold, Mildew, and Water Damage
Spot early signs of moisture intrusion before they worsen.
8. Compliance with waterproofing industry standards
Review waterproofing assembly and transition components for possible moisture intrusion.
9. Recommendations and Next Steps
Provide a full report outlining observations of any failed components, urgent repairs or recommended mitigation measures.
How Often Should You Get a Deck Inspection?
According to California state law:
- SB 721 (Apartment Buildings):
- Initial inspection was due by January 1, 2025 amended to Jan. 1 2026.
- Then every 6 years
- Initial inspection was due by January 1, 2025 amended to Jan. 1 2026.
- SB 326 (Condominiums & HOAs):
- Initial inspection was due by January 1, 2025
- Then every 9 years
- Initial inspection was due by January 1, 2025
Note: If your inspection reveals life-safety hazards, those repairs must be addressed immediately—and documented accordingly.
Benefits of Hiring a Professional for Deck Inspections
When it comes to SB 721 and SB 326 compliance, hiring a qualified inspection professional is critical. These inspections are highly regulated and require expertise in structural safety, California building codes, and statutory reporting.
Expertise in Identifying Hidden Issues
Licensed and qualified inspectors know what to look for—especially when it comes to aging wood and waterproofed structures, concealed water damage, or compromised components that might not be visible to an untrained eye.
Ensures Legal Compliance
Professionals familiar with SB 721 (apartment buildings) and SB 326 (condominiums/HOAs) understand the inspection scope, documentation, and frequency required by law. They’ll ensure you meet the exact specifications to avoid violations or enforcement action.
Prevents Fines and Liability
Non-compliance with either law can result in civil penalties, insurance complications, property sale delays or legal exposure if an accident occurs. Proactive inspections minimize these risks.
Delivers Complete Inspection Reports
A professional will provide a detailed, photo-documented report that satisfies legal requirements under SB 721 or SB 326. This includes findings, condition assessments, and clear repair recommendations.
Supports Statistically Valid Sampling (SB 326)
SB 326 requires inspections based on statistically significant sampling of Exterior Elevated Elements. Professionals with experience in condo inspections know how to meet this standard effectively.
Streamlines Project Planning and Budgeting
By identifying current and future repair needs, inspection reports help property managers and HOA boards plan maintenance strategically and avoid emergency repairs.
