California’s balcony law is a pair of statutes, Senate Bill 721 and Senate Bill 326, that require regular safety inspections of exterior elevated wood structures on residential buildings with three or more units. SB 721 covers apartments and set a first-inspection deadline of January 1, 2025. SB 326 covers condominiums and other common interest developments and set a first-inspection deadline of January 1, 2026. Owners and associations that have not inspected are already out of compliance, and if an inspection turns up problems, the clock on repairs starts the day the report is delivered.
Which Buildings and Structures Are Covered
Both laws apply to residential buildings with three or more dwelling units. The structures they target are exterior elevated elements: balconies, decks, porches, stairways, walkways, and entry structures that extend beyond the building’s exterior walls. A structure triggers the inspection requirement only if it has a walking surface more than six feet above ground level, is designed for human occupancy, and relies in whole or substantial part on wood or wood-based products for structural support.1California Legislative Information. California Health and Safety Code 17973
The waterproofing systems that protect those load-bearing components are also covered, including flashings, membranes, coatings, and sealants. Most balcony failures do not start with a broken beam. They start with failed waterproofing that lets moisture reach the wood framing, where it causes hidden rot over years. The inspection is designed to catch that progression before the structure becomes dangerous.
Single-family homes, duplexes, and buildings without wood-framed elevated elements are outside the scope of either statute.
SB 721 or SB 326: Which One Applies to You
SB 721 governs apartment buildings and other rental properties under the California Health and Safety Code.2California Legislative Information. SB-721 Building Standards – Decks and Balconies – Inspection SB 326 governs condominiums and other common interest developments managed by a homeowners association, and it operates under the California Civil Code.3California Legislative Information. California Civil Code 5551 SB 721 explicitly excludes common interest developments, so there is no overlap.
The practical differences come down to who can inspect, how many units get inspected, and how often. Condo associations face a tighter set of inspector qualifications and a statistical sampling requirement. Apartment owners have a broader pool of qualified inspectors but shorter intervals between inspections.
Inspection Deadlines and Recurring Cycles
For apartments under SB 721, the initial inspection was due by January 1, 2025, with reinspections required every six years.1California Legislative Information. California Health and Safety Code 17973
For condominiums under SB 326, the initial inspection was due by January 1, 2026, with reinspections required every nine years.3California Legislative Information. California Civil Code 5551
Inspection reports must be retained for at least two full inspection cycles. That means 12 years of records for apartments and 18 years for condominiums. Starting January 1, 2026, condominium inspection reports also became part of the association records that members and prospective buyers can request to review.3California Legislative Information. California Civil Code 5551
Who Can Perform the Inspection
Apartments Under SB 721
Four categories of professionals qualify:
- Licensed architects.
- Licensed civil or structural engineers.
- Building contractors holding an A, B, or C-5 license 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 determined by the local jurisdiction.
Inspectors cannot be employed by the local jurisdiction while performing these inspections, and the owner must hire the inspector directly.1California Legislative Information. California Health and Safety Code 17973
Condominiums Under SB 326
Only licensed structural engineers, civil engineers, or architects qualify. Contractors and certified building officials do not.3California Legislative Information. California Civil Code 5551 The narrower pool reflects the sampling requirement built into SB 326: the inspector must select a random, statistically significant sample of units that provides 95 percent confidence the results reflect the whole building, with a margin of error no greater than plus or minus five percent.
What the Inspection Covers
The inspection starts with a visual assessment using the least intrusive method necessary. That can include direct observation, moisture meters, borescopes, or infrared technology.3California Legislative Information. California Civil Code 5551 The inspector is looking for water intrusion, decay, fungal growth, or alterations that compromise load-bearing capacity.
If the visual inspection suggests water has penetrated the waterproofing and could be damaging load-bearing components, the inspector may move to further intrusive testing, opening portions of the structure to examine framing directly. For SB 721 properties, the statute requires the inspector to identify every type of exterior elevated element that, if defective, would threaten occupant safety.1California Legislative Information. California Health and Safety Code 17973
The inspector’s written report must describe the current condition of the elements, assess their remaining useful life, and recommend any necessary repairs. For condominiums, the report must also identify the components inspected and note any further inspection the board should consider.3California Legislative Information. California Civil Code 5551
Report Delivery and Emergency Findings
Under SB 721, the inspector must deliver a stamped or signed written report to the owner within 45 days of completing the inspection.1California Legislative Information. California Health and Safety Code 17973 Under normal conditions the report stays with the owner and does not need to be filed with the local government.
The timeline compresses when the inspector finds an emergency. If any element poses an immediate threat to occupant safety, the inspector must deliver the report to both the owner and the local enforcement agency within 15 days of completing it. The owner must take preventive measures immediately, at minimum blocking occupant access to the structure until emergency repairs are finished.
Condominiums work the same way with one difference in who receives the report. When the inspector finds an immediate safety threat, the report goes to the association’s board of directors immediately and to the local code enforcement agency within 15 days.3California Legislative Information. California Civil Code 5551 The association must prevent occupant access to the affected element until repairs are inspected and approved by the local enforcement agency. Local enforcement agencies can compel immediate repairs, including through emergency special assessments if the association lacks funds.
Repair Timelines After the Report
Getting the inspection done is only half of the obligation. If the report identifies problems that are not emergencies, repair deadlines start running.
For apartment buildings, the owner must apply for a repair permit within 120 days of receiving the inspection report. Once the permit is approved, the owner has another 120 days to complete the repairs. If the owner has not complied within 180 days total, the inspector is required to notify the local enforcement agency and the owner. If repairs still are not complete within 30 days of that notice, daily fines begin.1California Legislative Information. California Health and Safety Code 17973
For condominiums, the statute does not spell out the same rigid day count. The local enforcement agency has authority to set repair timelines and compel compliance once it receives a report identifying safety concerns. Most local agencies apply timelines comparable to the SB 721 framework.
Fines and Liability for Noncompliance
Fines for failing to complete required repairs range from $100 to $500 per day, based on a fee schedule set by the local enforcement agency. They do not kick in the moment a deadline passes. The owner has 180 days after the report to complete repairs, and if that deadline is missed, the inspector notifies the enforcement agency and the owner gets one more 30-day window. Daily fines begin after that grace period expires, unless the local agency grants an extension.1California Legislative Information. California Health and Safety Code 17973
At $500 per day, fines add up to over $15,000 a month. The bigger exposure is not the fine. An owner who ignores a documented structural deficiency and whose balcony later injures someone faces negligence liability that dwarfs any regulatory penalty, and the inspection report becomes direct evidence that the owner knew about the problem.
What to Budget
Inspection pricing varies by property size, number of balconies, and location. Comprehensive inspections with a full written report generally run between $200 and $400 per balcony. Properties with difficult access, extensive intrusive testing, or many elevated elements cost more. Demand for qualified inspectors spikes in the months before compliance dates, and pricing reflects that, so schedule early.
Repairs are a separate and often larger expense. Wood-framed balcony repairs typically range from roughly $500 to $3,500 per unit depending on the extent of deterioration, and severely compromised structures can cost substantially more. For condo associations, those costs flow through the reserve fund or a special assessment, and the findings should be shared with the reserve study professional because they can change funding levels and monthly dues.
