Balcony Inspection & Structural Repair per SB-721 (California Law)

PiersPro — Foundation Repair, Structural Reinforcement & Waterproofing Experts in California

California has officially moved into full enforcement of SB-721 and SB-326 — two laws created to prevent balcony collapses, structural failures, injuries, and multi-million-dollar lawsuits. The initial deadlines have passed, and many property owners in 2025 are now out of compliance.

PiersPro specializes in structural repairs, waterproofing, wood restoration, load-bearing reinforcement, and advanced engineering solutions. We help property owners bring their buildings into full compliance and eliminate safety hazards in elevated exterior structures.

1. What Is SB-721? (Official Source)

Full law text: California SB-721 Bill Text

SB-721 requires safety inspections of Exterior Elevated Elements (EEE) in all rental residential buildings with 3 or more units. These elevated structures include:

  • Balconies
  • Exterior decks
  • Walkways & corridors
  • Landings & stair platforms
  • Any exterior element over 6 feet above ground supported by wood

The law was implemented after the tragic Berkeley balcony collapse, caused by hidden wood decay under failed waterproofing. SB-721 ensures these structures are safe, load-bearing, and free of rot or deterioration.

2. What Is SB-326? (Official Source)

Full law text: California SB-326 Bill Text

SB-326 applies to condominiums and HOAs. The inspection requirements are similar, but only the following professionals may conduct the inspection:

  • Licensed Structural Engineers (SE)
  • Licensed Civil Engineers (PE)
  • Licensed Architects

PiersPro works directly with trusted licensed engineers to perform SB-326 inspections for HOAs and then provides complete structural and waterproofing repairs recommended by the engineer.

3. Deadlines Have Passed — Most Buildings Are Now Out of Compliance

Both SB-721 and SB-326 required the initial inspection to be completed by January 1, 2025. Today, enforcement has begun in many California counties:

  • Violation notices are being issued
  • “Unsafe” building designations are increasing
  • City inspectors request proof of compliance
  • Emergency repairs may be mandated
  • Units can be prohibited from being rented until fixed

This is why now is the critical time to complete inspections and structural repairs through specialists like PiersPro.

4. Penalties & Financial Liability for Non-Compliance

SB-721 Penalties (Rental Buildings)

Enforcement text from Health & Safety Code §17973: HSC §17973

Failure to comply may result in:

  • Fines up to $500 per day
  • City-ordered emergency repairs
  • Orders to vacate unsafe units
  • Insurance cancellation or premium increases
  • Major liability in case of collapse or injury

SB-326 Penalties (HOA)

Non-compliant HOAs may face:

  • Lawsuits from homeowners
  • Personal liability for board members
  • Special assessments for emergency repairs
  • Insurance coverage disputes

5. Why SB-721 Exists — Real Risks of Structural Failure

Most elevated exterior failures are caused by:

  • Hidden rot inside wood framing
  • Failed waterproofing membranes
  • Termite damage
  • Corroded fasteners and connectors
  • Improper construction or aging structures

These issues lead to:

  • Dangerous structural instability
  • Partial or total balcony collapse
  • Tenant injuries and fatalities
  • Multi-million-dollar lawsuits against owners

PiersPro specializes in identifying and correcting exactly these risks — before the structure fails.

6. Which Buildings Must Comply?

SB-721 Applies To:

  • Triplexes and four-plexes
  • Multi-unit residential buildings (3+ units)
  • Mixed-use buildings with residential units
  • Any rented residential structure with elevated exterior elements

SB-721 Does Not Apply To:

  • Single-family homes
  • Duplexes
  • Non-residential commercial buildings
