SB 721 (Health & Safety Code §17973) requires owners of California apartment buildings with three or more units to inspect exterior elevated elements—balconies, decks, walkways, and stairs—for structural safety. The deadline, extended to January 1, 2026, by AB 2579, has now passed. Non-compliant owners face daily fines of $100 to $500. This guide explains who must comply, what gets inspected, who can inspect, repair timelines, penalties, and how SB 721 differs from SB 326 for condominiums.
What Does SB 721 Require?
SB 721, codified as Health & Safety Code §17973, is California’s balcony and exterior elevated element inspection law for multifamily rental buildings with three or more dwelling units. Enacted in 2018 following the deadly 2015 Berkeley balcony collapse, SB 721 mandates periodic inspections of structural components that are exposed to weather and support occupant loads.
The law applies to apartment buildings and other rental properties—not condominiums or homeowner associations, which fall under a separate statute (SB 326). Understanding which law applies to your property is critical for compliance. For a broader overview of 2026 construction law changes, see our 2026 California Construction Law Update.
What Is the SB 721 Inspection Deadline?
The original SB 721 deadline was January 1, 2025. However, the Legislature passed AB 2579, which extended the deadline by one year to January 1, 2026. This extension has now passed. Property owners who have not completed their inspections are currently out of compliance and subject to enforcement action.
After the initial inspection, property owners must re-inspect every six years. This recurring obligation means compliance is not a one-time event—it is an ongoing property management responsibility.
Who Must Comply With SB 721?
SB 721 applies to owners of buildings that meet all of the following criteria:
- Building type: Multifamily residential (apartments, rental properties)
- Unit count: Three or more dwelling units
- Construction: Contains exterior elevated elements that are substantially supported by wood or wood-based products
Important distinction: SB 721 does not apply to condominiums or common interest developments (CIDs). Those properties are governed by SB 326 (Civil Code §5551), which has different requirements and a different deadline. Visit our HOA law page for details on condominium obligations.
What Building Elements Must Be Inspected Under SB 721?
SB 721 covers all exterior elevated elements that pose a risk of structural failure, including:
- Balconies
- Decks
- Exterior walkways and corridors
- Exterior stairways
- Elevated landings and platforms
- Any similar structure that extends beyond the building’s exterior walls and is elevated above ground level
The common thread is that these elements are exposed to the elements (rain, sun, humidity) and bear the weight of occupants. Years of water intrusion can cause hidden rot in wood framing—exactly the failure mode that caused the 2015 Berkeley tragedy.
Who Is Qualified to Perform SB 721 Inspections?
SB 721 permits inspections by the following licensed professionals:
- Licensed architects
- Licensed structural, civil, or mechanical engineers
- Licensed general contractors (A license), general building contractors (B license), or framing/carpentry contractors (C-5 license) who have a minimum of five years of experience
This is a broader group of qualified inspectors than SB 326 allows for condominiums. Under SB 326, general contractors cannot perform inspections—only licensed engineers and architects qualify. Make sure you hire the right professional for your building type.
What Are the SB 721 Inspection Requirements?
The inspection itself must meet specific statutory standards:
- Sampling rate: A minimum of 15% of each type of exterior elevated element must be inspected.
- Direct visual inspection: Inspectors must conduct hands-on visual assessments, not just visual surveys from the ground.
- Exploratory openings: Where necessary, inspectors must open wall or deck surfaces to examine concealed framing, connections, and waterproofing membranes.
- Written report: The inspector must produce a written report identifying any deficiencies and categorizing them by urgency.
If the initial sample reveals significant problems, the inspector may expand the scope to additional elements. Property owners should budget for potential scope expansion when planning their inspections.
What Is the Repair Timeline After an SB 721 Inspection?
Once an inspection identifies necessary repairs, the property owner has 120 days to complete all repairs. This timeline is aggressive, particularly for properties with extensive deterioration. Owners should:
- Engage a qualified contractor immediately after receiving the inspection report
- Prioritize any elements identified as immediate safety hazards (the inspector may require emergency shoring or closure)
- Document all repairs and obtain verification from the original inspector or another qualified professional
- Submit the completed repair documentation to the local enforcement agency as required
What Are the Penalties for Non-Compliance With SB 721?
Property owners who fail to complete required inspections face daily civil penalties ranging from $100 to $500, imposed by the local code enforcement agency. These penalties accrue each day the violation continues, meaning a property that remains non-compliant for a year could face fines exceeding $100,000.
Beyond monetary penalties, non-compliance creates significant liability exposure:
- Personal injury claims: If a balcony or elevated element fails and injures someone, the owner’s failure to inspect under SB 721 becomes powerful evidence of negligence.
- Insurance coverage issues: Insurers may deny claims or decline to renew policies for properties that have not completed required inspections.
- Sale complications: Buyers and lenders increasingly require proof of SB 721 compliance during due diligence.
SB 721 vs. SB 326: How Do These Balcony Inspection Laws Compare?
Property owners frequently confuse SB 721 (apartments) and SB 326 (condominiums). The table below highlights the key differences:
| Requirement | SB 721 (Apartments) | SB 326 (Condominiums) |
| Statute | Health & Safety Code §17973 | Civil Code §5551 |
| Applies to | Rental buildings (3+ units) | Condos/CIDs (3+ units) |
| Deadline | Jan. 1, 2026 (extended by AB 2579) | Jan. 1, 2025 (no extension) |
| Qualified inspectors | Architects, engineers, or contractors (A/B/C-5 with 5 yrs exp.) | Architects, structural engineers, or civil engineers only |
| Sampling | Minimum 15% of each element type | 95% confidence / 5% margin of error |
| Inspection cycle | Every 6 years | Every 9 years |
| Penalties | $100–$500/day | Varies by jurisdiction |
| Reporting | Written report to owner | Board meeting + written summary to all owners within 15 days |
What Should You Do if You Missed the SB 721 Deadline?
If your property has not been inspected, take these steps immediately:
- 1. Hire a qualified inspector now. Contact a licensed architect, engineer, or qualified contractor. Demand is high, so early engagement is critical.
- 2. Notify your insurance carrier. Proactive disclosure may help preserve coverage and demonstrate good faith.
- 3. Document your efforts. Keep records of when you engaged an inspector, when inspections are scheduled, and any communications with enforcement agencies.
- 4. Budget for repairs. Set aside funds for the 120-day repair window. Deferring repairs compounds your legal exposure.
- 5. Consult a construction law attorney. An attorney can help you respond to enforcement actions, negotiate penalty reductions, and address any disputes with tenants or inspectors.

Frequently Asked Questions
Q: Does SB 721 apply to my duplex?
A: No. SB 721 applies only to multifamily residential buildings with three or more dwelling units. A duplex (two units) is not covered.
Q: Can a general contractor perform an SB 721 inspection?
A: Yes, but only if the contractor holds an A (general engineering), B (general building), or C-5 (framing/carpentry) license and has at least five years of experience. This is different from SB 326, which does not permit general contractor inspections.
Q: Did AB 2579 also extend the SB 326 deadline for condos?
A: No. AB 2579 extended only the SB 721 deadline for apartment buildings. The SB 326 deadline for condominiums remained January 1, 2025, with no extension.
Q: How often must I re-inspect under SB 721?
A: After the initial inspection, SB 721 requires re-inspection every six years. SB 326 (condominiums) uses a nine-year cycle.
Q: What if my inspector finds no problems?
A: If the inspection reveals no deficiencies, the inspector will issue a clean report. You should retain this report for your records, provide copies to your insurance carrier, and calendar the next inspection date (six years later).
