California Landlords: Is Your Balcony Safe—and Compliant?

A balcony may look perfectly sound from the courtyard below while moisture, deterioration, or dry rot quietly damages its structural supports.

That is why California requires certain balconies, decks, stairways, walkways, and other elevated exterior structures at multifamily properties to be inspected by qualified professionals. For many rental property owners, these requirements are governed by Senate Bill 721, now codified in California Health and Safety Code Section 17973.

The first statewide inspection deadline for existing covered rental buildings was January 1, 2026. Landlords who have not yet confirmed or documented compliance should address the matter promptly rather than waiting for visible damage, a tenant complaint, a sale, or a local enforcement action.

What Is California’s SB 721 Balcony Inspection Law?

SB 721 established inspection and repair requirements for certain “exterior elevated elements,” commonly abbreviated as EEEs, at multifamily rental buildings.

The law is intended to identify deterioration in structural and waterproofing components before it creates a threat to residents or the public. An inspection evaluates whether covered structures are generally safe, functioning properly, and free from hazardous conditions caused by decay, fungus, deterioration, or improper alterations.

Although it is commonly called the California balcony inspection law, the requirement can cover considerably more than balconies.

Which Rental Properties Are Covered?

California Health and Safety Code Section 17973 generally applies to buildings that contain three or more multifamily dwelling units and have qualifying exterior elevated elements.

A covered exterior elevated element generally must:
  • Extend beyond an exterior wall of the building
  • Have a walking surface more than six feet above ground level
  • Be designed for people to occupy or use
  • Rely substantially on wood or wood-based products for structural support

Covered structures may include balconies, decks, porches, exterior stairways, walkways, entry structures, supports, and railings.

A duplex without another dwelling unit generally would not meet the three-unit threshold under this statewide provision. A three-unit or larger building may be covered, but only if it also contains structures meeting the law’s definition.

Because local governments can adopt requirements that are stricter than the statewide standard, owners should also review the rules of the city or county where the property is located.

What Was the SB 721 Inspection Deadline?

The first inspection of existing covered rental properties was required to be completed by January 1, 2026. Subsequent inspections must generally be completed every six years.

For newer buildings whose permit applications were submitted on or after January 1, 2019, the first inspection generally must occur within six years after the local jurisdiction issues the certificate of occupancy.

Since the initial deadline has passed, an owner who cannot locate a compliant inspection report should not assume that an ordinary property inspection, appraisal, pest report, or maintenance walkthrough satisfied SB 721. The owner should consult an appropriately qualified inspector and the applicable local building or code-enforcement department.

Who Can Perform an SB 721 Inspection?

The law permits inspections to be performed by specified qualified professionals, including:
  • A licensed architect
  • A licensed civil or structural engineer
  • A contractor holding an eligible A, B, or C-5 license, subject to the law’s experience requirements
  • A certified building inspector or building official recognized by the local jurisdiction

The inspector must be hired by the building owner and cannot be employed by the local jurisdiction while performing the inspection.

Before hiring someone, owners should verify the professional’s license, relevant experience, insurance, proposed inspection method, report format, and familiarity with the requirements of the local jurisdiction.

What Does the Inspection Cover?

For rental buildings subject to SB 721, the inspection must assess the load-bearing components and associated waterproofing elements of at least 15% of each type of covered exterior elevated element.

Associated waterproofing elements can include membranes, coatings, flashings, and sealants that help protect structural components from water exposure. The evaluation addresses:
  • The structure’s current condition
  • Its expected future performance
  • Its projected service life
  • Whether further inspection is recommended

The inspector must provide the owner or the owner’s designated agent with a signed or stamped written report generally within 45 days after completing the inspection. The report must contain photographs, applicable test results, and enough narrative information to establish a condition baseline for future inspections.

What Happens When the Inspector Finds a Problem?

The required response depends on the seriousness of the condition.

Immediate safety threats

When an exterior elevated element presents an immediate threat, preventive measures must be taken immediately. That can include blocking occupant access, shoring the structure, and completing emergency repairs.

The inspector must provide qualifying reports to the building owner and local enforcement agency within the timelines established by the statute. Emergency repairs must also be inspected and reported to the local agency.

Nonemergency repairs

When corrective work is required but the condition does not present an immediate threat, the owner generally must apply for the necessary permit within 120 days after receiving the inspection report.

Once the permit is approved, the owner generally has another 120 days to complete the work, unless the local enforcement agency grants an extension.

Failure to complete required repairs can eventually result in civil penalties of $100 to $500 per day, depending on the local authority’s fee schedule, as well as the potential recording of a building safety lien.

Which Warning Signs Should Landlords Watch For?

A visual warning sign does not determine whether a property is legally covered, and a landlord’s walkthrough does not replace a required professional inspection. Nevertheless, owners and property managers should promptly investigate conditions such as:
  • Soft, sagging, or uneven walking surfaces
  • Cracked or separating waterproof coatings
  • Rust stains or corrosion near fasteners
  • Loose railings
  • Peeling paint or recurring water stains
  • Wood discoloration or visible decay
  • Water intrusion around doors, walls, and flashing
  • Improvised repairs or unpermitted alterations

Small waterproofing failures can allow moisture to reach concealed structural components. Addressing leaks and deterioration early may reduce safety risks and prevent a limited maintenance issue from becoming a major structural repair.

SB 721 Versus SB 326: What Is the Difference?

SB 721 primarily addresses qualifying multifamily rental buildings and is found in Health and Safety Code Section 17973.

A separate law commonly known as SB 326 applies to certain condominium projects and common interest developments. Under California Civil Code Section 5551, an association of a qualifying condominium project must arrange an inspection of a statistically significant sample of the exterior elevated elements for which the association has maintenance or repair responsibility.

SB 326 inspections must be performed by a licensed structural or civil engineer or architect. The first inspection deadline was January 1, 2025, with inspections generally required every nine years thereafter.

Owners of individual condominium units should therefore communicate with their homeowners association rather than assuming the responsibility falls entirely on the unit owner.

Inspection Reports Are Long-Term Property Records

SB 721 inspection reports must be retained in the building owner’s permanent records for at least two inspection cycles. The reports must also be disclosed and delivered to a buyer when the building is subsequently sold.

Owners should maintain an organized compliance file containing:
  • The inspector’s proposal and license information
  • The initial inspection report
  • Photographs and test results
  • Notices sent to residents
  • Permit applications
  • Contractor proposals and invoices
  • Local agency correspondence
  • Final reports or confirmation that repairs were completed

Well-organized records can make future inspections, refinancing, insurance reviews, and property sales easier to manage.

What Should California Landlords Do Now?

Property owners can begin with four practical steps:

  1. Confirm whether the property is covered. Identify the number of dwelling units and inventory all balconies, stairs, walkways, decks, porches, and elevated entry structures.
  2. Locate the inspection report. Confirm that it was prepared by an eligible professional and satisfies the requirements of Section 17973.
  3. Review outstanding recommendations. Verify that required permits, repairs, follow-up inspections, and local filings were completed.
  4. Create the next inspection reminder. Record the applicable six-year inspection cycle and retain the report with the property’s permanent records.

Owners should not ignore the requirement merely because a balcony appears stable. Some of the most serious forms of water damage and decay may be concealed behind finishes or waterproofing systems.

Frequently Asked Questions

Are all California rental balconies subject to SB 721?

No. The statewide law generally concerns qualifying exterior elevated elements at buildings containing three or more multifamily dwelling units. The structure must also meet criteria involving height, use, location, and wood-based structural support.

Are metal or concrete balconies covered?

The statutory definition focuses on exterior elevated elements that rely wholly or substantially on wood or wood-based products for structural support or stability. A qualified professional should evaluate mixed-material or unclear construction.

Can a general home inspector perform the inspection?

Only when the person possesses one of the qualifications authorized by the statute and satisfies any applicable experience or local-jurisdiction requirements. A standard home inspection does not automatically constitute an SB 721 inspection.

How frequently are rental balconies inspected?

Covered rental properties are generally inspected every six years. Different timing may apply to newer buildings based on the date of the permit application and certificate of occupancy.

Does SB 721 apply to condominium associations?

Common interest developments are excluded from Health and Safety Code Section 17973. Qualifying condominium associations are instead generally governed by Civil Code Section 5551, commonly associated with SB 326.
