SB 721: Balcony Inspection Deadlines, Reports, and Penalties

California’s SB 721 balcony inspection law requires the owner of any apartment building with three or more units to hire a qualified professional to inspect wood-framed balconies, decks, stairways, walkways, and similar elevated structures, file the report with the local building department, and complete any repairs the inspector identifies. The first inspection must be done by January 1, 2026, and a new one is required every six years after that. The rule is codified at California Health and Safety Code Section 17973.¹

Which Buildings and Which Structures Are Covered

SB 721 applies to buildings with three or more multifamily dwelling units. Within those buildings, the inspection requirement attaches only to “exterior elevated elements” that meet all four of these conditions:

The structure is a balcony, deck, porch, stairway, walkway, or entry structure, including its supports and railings.
Its walking surface sits more than six feet above ground level.
It is designed for human occupancy or use.
It relies in whole or substantial part on wood or wood-based products for structural support.

All four have to be present. A second-story concrete stairway is out. A wooden porch three feet off the ground is out. A wood-framed second-floor apartment balcony is in.¹ If the elevated structures on your property are built entirely with steel or concrete and contain no wood load-bearing components, SB 721 does not apply.

One boundary worth stating up front: condominiums and other common interest developments are not covered by SB 721. Those properties fall under SB 326 (Civil Code Section 5551), which has its own timeline and rules. See the comparison further down if you manage a condo association.

The 2026 Deadline and the Six-Year Cycle

The original deadline for the first round of inspections was January 1, 2025. AB 2579, passed in 2024, pushed that to January 1, 2026. After the initial inspection, a fresh inspection is required every six years. A property first inspected in 2025 is next due in 2031.

Newer buildings follow a different clock. If the building received its building permit on or after January 1, 2019, the first inspection must occur within six years of the certificate of occupancy, and then every six years.²

Who Can Legally Perform the Inspection

The statute limits qualified inspectors to four categories:

Licensed architects registered through the California Architects Board.
Licensed civil or structural engineers registered through the Board for Professional Engineers.
Licensed contractors holding an A (General Engineering), B (General Building), or C-5 (Framing and Rough Carpentry) classification from the Contractors State License Board, with at least five years of experience constructing multistory wood-frame buildings.
Certified building inspectors or building officials from a recognized state, national, or international association, as approved by the local jurisdiction.

The five-year experience rule for contractors trips owners up often. A newly licensed B contractor does not qualify, even if the license is active.² An inspection performed by someone outside these categories will not satisfy the statute. Verify your inspector’s license through the California Department of Consumer Affairs before signing a contract.

What the Report Must Contain

The inspector has to evaluate the load-bearing components and the waterproofing elements of each covered structure. At a minimum, the report must address, as of the inspection date:

The current physical condition of each element, identifying any that are defective, decayed, or deteriorated enough to no longer meet load requirements.
The projected service life of the load-bearing components and waterproofing systems.
Any recommendations for further inspection.

The report must also state clearly whether any element presents an immediate threat to occupant safety, whether access needs to be restricted, and whether emergency repairs or temporary shoring are required.¹ If your local enforcement agency publishes a standardized form, the inspector must use it.

What to Do After the Inspection

What happens next depends on what the inspector found.

Immediate Safety Threats

When the inspector flags an immediate danger to occupants, a copy of the report must go to the building owner and the local enforcement agency within 15 days of completion. The owner has to take preventive action right away, which typically means closing off the affected balcony or stairway and arranging emergency shoring or repair.¹

Non-Emergency Repairs

If corrective work is needed but no immediate threat exists, the owner has 120 days from the date of the inspection report to apply for a building permit. Once the permit is approved, another 120 days to finish the repairs. Local agencies may grant extensions.²

File the completed report with your local building department or designated enforcement agency either way. A clean report is still the proof of compliance.

Penalties for Missing the Deadline or Skipping Repairs

Penalties escalate. If an owner fails to complete required repairs within 180 days, the inspector must notify the local enforcement agency and the owner. If repairs are still not finished 30 days after that notice, civil penalties of $100 to $500 per day begin to accrue until the work is done. The daily amount depends on the local jurisdiction’s fee schedule.²

On a larger property, those daily fines add up quickly, and the exposure does not end there. The local jurisdiction can record a building safety lien against the property with the county recorder. That lien carries the priority of a judgment lien and must be resolved before a clean sale. If the owner still fails to pay, the jurisdiction can foreclose. Enforcement agencies can also recover their own costs for pursuing compliance.²

Records and Disclosure at Sale

Owners must keep copies of every inspection report in their permanent records for at least two inspection cycles. Given the six-year interval, that works out to 12 years. When the building is sold, the owner must disclose and deliver those reports to the buyer at the time of the transaction.¹ This is a statutory disclosure obligation, not an optional courtesy. Buyers doing due diligence on a multifamily property should ask for the reports; sellers who do not produce them create legal exposure for themselves.

SB 721 vs. SB 326 for Condominiums

Owners and HOA boards mix these up constantly. SB 721 governs multifamily rental buildings. SB 326 (Civil Code Section 5551) governs condominiums and other common interest developments. The main differences:

Inspection interval: SB 721 is every six years; SB 326 is every nine years.
Qualified inspectors: SB 721 allows architects, engineers, qualified contractors, and certified building inspectors. SB 326 limits inspectors to licensed structural engineers, architects, or civil engineers — no contractors.
Scope: SB 721 requires inspection of all exterior elevated elements. SB 326 allows a statistically significant sample providing 95 percent confidence with no more than a 5 percent margin of error.
Who is responsible: Under SB 721, the building owner. Under SB 326, the HOA board.

Condominium complex with three or more units per building: SB 326. Apartment building with three or more units: SB 721.

Cost and Tax Treatment

The statute does not cap inspection fees, and prices vary with building size, number of elevated elements, and local market rates. Published industry estimates run from a few hundred dollars per element for a visual assessment to several thousand dollars for a full evaluation of a larger complex. For a property with many balconies, getting multiple bids is worth the time.

Repairs are a separate expense and often the bigger one. Replacing rotted framing on a single balcony can run into the thousands; a building with widespread water intrusion can face six-figure costs. Permit fees for structural work vary by jurisdiction.

On taxes, the IRS requires property owners to capitalize costs that improve tangible property under Section 263(a) of the Internal Revenue Code. Structural repairs that materially improve or restore a building component generally must be capitalized and depreciated rather than deducted as a current expense. The de minimis safe harbor election allows a current deduction for amounts up to $5,000 per invoice for taxpayers with an applicable financial statement, or $2,500 per invoice for those without one.³ Most SB 721 repair projects will exceed those thresholds. Talk to a tax professional familiar with rental property before deciding how to treat the costs.
