SB-721 Inspection Requirements: The Complete Guide for California Property Owners

Overview of California SB-721 Inspection Requirements

California Senate Bill 721, the Balcony Inspection Law, was enacted in 2018 after several high-profile balcony failures. It applies to multifamily rental buildings with three or more dwelling units across California, while condominiums governed by HOAs are covered by a separate law, SB-326.

Exterior Elevated Elements (EEEs) include balconies, decks, porches, stairways, and walkways that are more than six feet above grade and supported by wood or wood-based materials.

The law protects residents by requiring initial inspections by January 1, 2026, and then at least every six years, with timely repairs when hazards are found. For scope, process, and what inspectors check, see our SB-721 inspections page.

As a trusted local contractor serving Walnut Creek and the greater Bay Area, Golden State Builders Group provides comprehensive SB-721 inspections, structural evaluations, repairs, documentation, and long-term maintenance. Disc

What Structures Require an SB-721 Inspection?

SB-721 applies to multifamily buildings containing three or more dwelling units. The following components require inspection:

Exterior Elevated Elements (EEEs) Include:

  • Balconies: Elevated outdoor platforms that may hide moisture intrusion or structural decay within concealed framing.
  • Decks & Raised Platforms: Often exposed to weather, making them vulnerable to rot, corrosion, and waterproofing failure.
  • Exterior Stairways & Landings: Critical structural components whose failure can cause severe safety hazards.
  • Walkways & Elevated Corridors: Load‑bearing pathways requiring regular inspections due to constant foot traffic.
  • Catwalks: Narrow elevated connectors where railing integrity and attachment strength are essential.
  • Ramps: Sloped exterior structures that must ensure proper drainage to prevent moisture-related deterioration.
  • Guardrails, Handrails & Connections: Essential fall‑prevention systems that must have strong, corrosion‑resistant fasteners.

Inspection Timeline, Deadlines & Frequency

To stay compliant with California state law, property owners must adhere to strict timelines:

Initial Compliance: First inspection must be completed by January 1, 2025.

Ongoing Compliance: Inspections must occur every 6 years after the initial inspection.

Transfer of Ownership: Reports must be disclosed to buyers during property transfer.

What an SB-721 Inspection Includes

A qualified inspector assesses structural, functional, and safety concerns. Inspections may involve visual review, moisture readings, probing, borescope evaluations, and selective opening of concealed areas.

1. Structural Integrity Analysis

Inspectors evaluate:

  • Load‑Bearing Components: Ensuring beams, joists, posts, and support assemblies can safely carry intended loads.
  • Wood Framing: Checking for hidden rot, swelling, splitting, or insect damage that compromises structural strength.
  • Connectors & Fasteners: Examining joist hangers, brackets, screws, and nails for rust, corrosion, or loosening.
  • Structural Stability & Deflection: Identifying sagging, slope inconsistencies, or movement indicating deeper failure.

2. Waterproofing & Weatherproofing Review

Critical preventive measures include:

  • Flashing Integrity: Ensuring transition points, such as edges and wall intersections, are properly sealed against water.
  • Waterproof Membranes: Reviewing the condition of concealed moisture barriers that protect structural framing.
  • Coatings & Sealants: Checking for worn or cracked protective coatings that allow water penetration.
  • High‑Risk Transition Zones: Evaluating door thresholds, siding/deck intersections, and metal transitions prone to leakage.

3. Surface & Component Assessment

Includes examination of:

  • Rot & Fungal Decay: Identifying soft, crumbling, or discolored wood indicating long‑term moisture exposure.
  • Water Infiltration Indicators: Stains, bubbling paint, or mineral deposits showing water movement into structural layers.
  • Rust or Corrosion: Metal degradation that weakens essential connectors and accelerates failure.
  • Loose or Compromised Railings: Safety hazards often caused by rusted fasteners or hidden dry rot.
  • Pest‑Related Damage: Termite or beetle activity that compromises the integrity of wood framing.

SB-721 Repair Requirements & Timelines

Repair urgency is categorized by the inspector based on structural significance.

Non-Urgent Repairs (Standard Deficiencies)

  • Must be corrected within 120 days of the inspection report.
  • Extensions may be granted if work is already scheduled and underway.

Urgent Life-Safety Hazards

If the inspector identifies immediate safety risks:

  • The inspector will notify the building owner and local enforcement.
  • Repairs must begin within 30 days.
  • Temporary tenant relocation may be required in severe cases.

Inspection Findings & Compliance Documentation

After completing an inspection, you will receive:

1. Comprehensive Written Report

This document includes:

  • Detailed findings
  • Photos of every evaluated element
  • Moisture readings
  • Structural assessment notes
  • Repair recommendations + urgency categories

2. Documentation Retention Requirements

Property owners must keep records for 12 years (two inspection cycles), ensuring documentation is available for audits, repairs, compliance verification, and future ownership transfers to maintain safety and legal accuracy.

3. Post-Repair Certification

When repairs are completed, owners receive:

  • Proof of correction
  • Contractor documentation
  • Updated compliance record

SB-721 vs. SB-326: What’s the Difference?

Many property owners confuse these two laws. Here’s how they differ:

SB-721

  • Applies to apartment buildings (multifamily units)
  • Inspections by licensed contractors, engineers, or architects
  • Occurs every 6 years

SB-326

  • Applies to HOA-managed condominiums
  • Inspections by licensed structural engineers or architects only
  • Occurs every 9 years

Golden State Builders Group serves both property types and can help clarify which requirements apply to your building.
