California Senate Bill 721: Inspections, Deadlines, and Penalties

California SB 721 requires owners of apartment buildings with three or more dwelling units to hire a qualified professional to inspect balconies, decks, stairways, and other exterior elevated wood-framed structures every six years, complete any repairs the inspector requires within statutory deadlines, and keep the reports on file. Miss a deadline and daily fines run from $100 to $500, with the local agency authorized to record a lien against the property. The law is codified at California Health and Safety Code Section 17973.¹

Which Buildings and Structures Are Covered

SB 721 applies to buildings with three or more multifamily dwelling units. Single-family homes and duplexes are outside its reach. If you own a condominium or your property is part of a common interest development, a different statute, SB 326, governs your inspections instead, with a nine-year cycle and a narrower list of qualified inspectors.

Within a covered building, the law targets “exterior elevated elements.” The statute means balconies, decks, porches, stairways, walkways, and entry structures that meet all of the following: they extend beyond the building’s exterior walls, they sit more than six feet above ground level, they are designed for human use, and they rely on wood or wood-based products for structural support.¹ Concrete-framed structures don’t count. The inspection also has to evaluate associated waterproofing — flashings, membranes, coatings, and sealants that protect load-bearing components from water.

The Six-Year Cycle and the 2026 Deadline

The original law set January 1, 2025 as the deadline for the first round of inspections. AB 2579 pushed that to January 1, 2026 for buildings that had not yet been inspected.² After that initial inspection, the building must be reinspected every six years for as long as it stands.

One exemption from the initial deadline: buildings inspected within three years before January 1, 2019 didn’t need another inspection just to satisfy the initial requirement. Those owners still fall under the six-year recurring cycle going forward.

Who Can Perform the Inspection

The owner hires and pays the inspector, but the statute limits who qualifies:

Licensed architects
Licensed civil or structural engineers
Building contractors holding an A (general engineering), B (general building), or C-5 (framing and rough carpentry) license from the Contractors State License Board, with at least five years of experience constructing multistory wood-frame buildings
Certified building inspectors or officials from a recognized state, national, or international association, as approved by the local jurisdiction

Employees of the local enforcement agency cannot perform SB 721 inspections, which keeps the inspection function independent from the enforcement function.¹

What the Inspection Covers

Inspectors are not required to look at every balcony and stairway. The statute calls for a representative sample of at least 15 percent of each type of exterior elevated element on the property.² On a building with 40 balconies, that’s at least six. Inspectors typically pick units on different sides and levels of the building so the sample reflects how weather and wear vary across the property.

The inspection is a direct visual examination of load-bearing components and waterproofing, and it may include exploratory openings where the inspector cuts into finishes to see hidden structural members. The inspector is checking whether the elements are in generally safe condition, in adequate working order, and free from hazards caused by fungus, deterioration, decay, or improper alterations.¹ Water damage is the most common finding, because it develops behind finishes long before it’s visible from the surface.

What the Report Must Contain

The inspector produces a stamped or signed written report and delivers it to the owner within 45 days of finishing the inspection. The report must address:²

The current condition of each inspected element
Expectations for future performance and projected remaining service life
Whether any elements need further or more invasive evaluation
Photographs, test results, and other documentation sufficient to serve as a baseline for future inspections
Whether any element poses an immediate safety threat and whether emergency repairs or restricted access are warranted

Each new inspection report must incorporate copies of prior reports so conditions can be tracked over time. Owners are required to keep the reports on file for at least two inspection cycles, which works out to twelve years. When a building sells, the records should go with the property.

If the inspector flags an immediate threat, a copy of the report goes to both the owner and the local enforcement agency within 15 days of completion. For non-emergency findings, only the owner receives the report; the local agency becomes involved later, and only if the owner misses the repair deadlines.

Repair Timelines After a Report Identifies Problems

When the inspection report identifies deficiencies that don’t pose an immediate safety threat, the repair timeline runs in two stages:

120 days from receiving the report to apply for a repair permit
120 days from permit approval to complete the repairs, unless the local agency grants an extension

If repairs aren’t finished within 180 days, the inspector must notify both the local enforcement agency and the owner.² That notification starts a 30-day clock. If the work still isn’t done when the 30 days expire, daily civil penalties begin.

Emergency conditions move faster. Because the report reaches the local agency within 15 days, the jurisdiction is engaged from the start and can require immediate action, including restricting occupant access to the affected structure and ordering shoring or emergency repairs.

Penalties and Liens for Non-Compliance

Civil penalties for missing repair deadlines run from $100 to $500 per day, with the exact figure set by the local jurisdiction’s fee schedule. The clock keeps ticking until repairs finish or the agency grants an extension.² At the top of the range, a six-month delay adds up to more than $90,000 before any repair work begins, and a building with multiple deficient elements can accumulate penalties on each.

The local enforcement agency can also record a building safety lien against the property. Once recorded, the lien has the force and priority of a judgment lien: it attaches to the property, it can interfere with a sale or refinance, and the jurisdiction can foreclose on it through a court action to collect unpaid penalties.²

What Inspections Typically Cost

SB 721 inspections generally run $75 to $400 per unit, depending on building size, the number and type of exterior elevated elements, how accessible those elements are, and local market rates. A 20-unit building might pay somewhere between $1,500 and $8,000 for a cycle. Repairs are a separate expense and can range from minor waterproofing work to structural rebuilds costing tens of thousands per element.

Catching water intrusion early, before it reaches load-bearing joists, is generally cheaper than emergency structural repairs done against a statutory deadline with daily penalties running in the background. Owners who plan for the six-year cycle as a scheduled maintenance cost tend to avoid the compressed timelines that make repairs most expensive.
