Elevated exterior decks are a common feature in multifamily properties across California—but they’re also one of the most overlooked when it comes to safety. In response to high-profile tragedies, California passed SB 326 and SB 721, mandating safety inspections for decks, balconies, walkways, and stairs in apartment buildings and condo complexes.If you manage, own, or live in a multifamily building, here’s everything you need to know about common deck issues, why they matter under the law, and how West Coast Deck Inspections can help keep your property safe and compliant.
The Importance of Professional Deck Inspections
Whether required by law or just part of smart property upkeep, professional deck inspection goes far beyond visual checks.
Beyond DIY
Even experienced property managers can miss serious structural damage. Inspectors use moisture meters, probes, and drones to find hidden decay or improper construction—especially in areas inaccessible from the surface.
Safety First
California laws require urgent hazards to be reported to local code officials within 15 days. Structural failure due to hidden rot or faulty connections can result in serious injuries or worse.
Longevity & Value
Routine inspections allow for smaller, affordable repairs instead of expensive rebuilds. A well-maintained deck enhances property value and tenant satisfaction.
Preventative Maintenance
Catching problems early extends the life of your deck and waterproofing systems—saving tens of thousands over time.
California SB 326 and SB 721 – What They Require
SB 721 (for apartments) and SB 326 (for HOAs) apply to elevated exterior elements such as decks, balconies, stairways, and walkways more than six feet above ground.
Key compliance deadlines:
- SB 721 (Apartment Buildings): First inspection due by January 1, 2025; every 6 years thereafter
- SB 326 (Condos/HOAs): First inspection due by January 1, 2025; every 9 years thereafter
Covered elements include:
- Wood-framed balconies, decks, staircases, and landings
- Load-bearing components such as joists, beams, and ledger boards
- Waterproofing systems and visible framing conditions
Inspection reports must include:
- Photo documentation of conditions
- Written evaluation of current safety and expected lifespan
- Mandatory reporting of immediate hazards to code officials
West Coast Deck Inspections is fully licensed to conduct SB 326 and SB 721 assessments in compliance with state law.
Common Deck Issues Found During Inspections
Even newer decks can develop significant issues over time. These are the most common deck problems flagged by inspectors:
Structural Problems
- Loose or Rotting Posts and Beams: Moisture intrusion or termite damage can compromise critical load paths.
- Weak or Improper Ledger Board Attachment: A deck that isn’t properly secured to the building can collapse under weight.
- Sagging or Warped Joists: Often caused by water damage or undersized materials.
Surface and Finish Damage
- Cracked or Splintering Boards: Tripping hazards and early signs of rot.
- Fading or Peeling Paint/Stain: UV damage exposes bare wood to water, accelerating decay.
Moisture and Rot
- Wood Rot in Hidden Areas: Often hidden behind stucco or siding, revealed only through invasive testing.
- Mold and Mildew Growth: Signs of water pooling or failed waterproof membranes.
Hardware and Fastener Issues
- Rusted Nails, Screws, and Connectors: Fasteners lose strength and compromise structural integrity.
- Loose Railings or Stairs: Any unsecured railing or stair tread is a red flag for safety violations.
Code Compliance Issues
- Incorrect Railing Height or Spacing: California code generally requires 36-inch height with 4-inch spacing for safety.
Improper Footings or Lack of Permits: Many older decks lack the proper foundation or documentation required by current code.
