SB-721 Compliance Checklist for San Diego Apartment Owners

If you own an apartment or multifamily building with three or more units in San Diego County, SB-721 requires a licensed inspection of every load-bearing balcony, deck, stairway and walkway that depends on wood framing. The first inspection deadline is January 1, 2026, set by AB 2579, with re-inspection every six years after that.

SB-721 lives in California Health & Safety Code section 17973. It was written after the 2015 Berkeley balcony collapse, and it targets the exact components that fail when concealed wood framing rots: the parts that hold people up in the air. Below is a practical checklist San Diego owners can work through, followed by the deadlines, qualifications and penalties you need to plan around. Statutes change, so confirm every detail against the current code before you rely on it.

Does SB-721 even apply to your building?

Before you schedule anything, confirm you are in scope. SB-721 applies to buildings with three or more multifamily dwelling units that have “exterior elevated elements” with a walking surface more than six feet above ground level, where the element relies on wood or wood-based products for structural support.

• In scope: apartment complexes, fourplexes and larger, and similar rental multifamily buildings of three-plus units.
• Out of scope for SB-721: condominiums and other common-interest developments governed by an HOA. Those fall under SB-326 (Civil Code 5551) instead, with its own deadlines and rules. If you are unsure which law governs your property, our SB-721 vs SB-326 balcony inspection guide walks through the distinction side by side.
• Not covered at all: elements made entirely of non-wood materials such as steel or concrete, and elements six feet or less above grade. When framing is concealed, do not assume it is steel or concrete just because the finish looks that way.

Many older San Diego apartment buildings, especially the wood-framed two- and three-story walk-ups common in El Cajon, La Mesa, City Heights and coastal North County, are squarely in scope.

What exterior elevated elements (EEEs) get inspected

SB-721 uses the term “exterior elevated elements” for the load-bearing components carried by wood framing. The inspection covers both the visible element and the structural and waterproofing systems that support it. Your inspector will look at:

• Balconies and decks more than six feet above grade, including the framing, ledger connections and posts.
• Exterior stairways and landings that depend on wood support.
• Elevated walkways and corridors serving upper units.
• Railings and guardrails where they are part of the load path or attached to the element.
• The associated waterproofing system – flashing, membranes, coatings and drainage – because in San Diego, water intrusion is the number-one driver of concealed wood decay, especially on the salt-air coast from Oceanside to Coronado.

The goal is to determine whether these elements are in a generally safe condition, performing as designed, and free from conditions that compromise their load-bearing capacity or waterproofing.

How many elements must be inspected: the sample size rule

SB-721 does not require every single balcony to be opened up. The statute requires a statistically significant sample of the exterior elevated elements. In practice the law frames this as inspecting enough elements to provide 95 percent confidence that the results reflect the whole building, with a margin set in the code.

What that means for you as an owner:

• On a large complex, the inspector selects a representative sample rather than touching all 200 balconies.
• If the sampled elements show problems, the scope typically expands, because the sample is meant to be representative of the whole.
• The inspection generally requires visual access to the framing, which can mean opening test areas or using methods that let the inspector see concealed conditions. Owners should plan for tenant notice and access.

The right sample, the right elements and defensible documentation are exactly what a qualified inspection delivers. You can see how we scope this on our SB-721 balcony inspection service page.

Who is legally allowed to perform the inspection

This is where owners most often get tripped up. Not just anyone can sign an SB-721 report. Health & Safety Code 17973 limits the inspection to specific qualified parties:

• A licensed architect.
• A licensed civil or structural engineer.
• A licensed general contractor, licensed building contractor (B-2) or other contractor with the relevant license classification and the required years of experience in the relevant field.
• A certified building inspector or certified building official recognized under the statute.

Confirm the inspector’s license and qualifications before work begins, and keep a copy on file. Note that SB-721’s allowable inspectors are broader than SB-326’s, which restricts condo balcony inspections to a licensed architect or structural engineer only.

Recordkeeping: what you must keep and for how long

The inspection is only half the job. SB-721 requires a written report, and the report has consequences:

• The inspector must provide a stamped or signed written report describing the condition of the inspected elements and identifying any that pose a threat to safety.
• The owner must retain the report in the building records and make it available on request. Plan to keep each report for at least two inspection cycles so you can show the inspection history.
• If the inspector finds conditions that pose an immediate threat to safety, the report must be delivered to the owner within a short window, and the owner must take emergency action – which can include barricading or restricting use of the element until repairs are made. Local enforcement agencies receive copies in those situations.

Repair timelines after the inspection

What you do with the findings is governed by the statute, not by your own schedule.

• Immediate-threat conditions: the owner must act right away to protect occupants, including preventing use of the unsafe element, and then pull permits and repair.
• Repairs that are needed but not an emergency: the owner must apply for permits within 120 days of receiving the report, and complete the repairs within 120 days of permit issuance, unless an extension is granted. Repairs must be performed by appropriately licensed contractors.
• No issues found: document the clean report, calendar the next inspection, and you are done until the cycle repeats.

Penalties for missing the SB-721 deadline

Non-compliance is not a paperwork slap. Under the statute, if a required repair is not completed in time, the local enforcement agency can impose a civil penalty and may record a building safety lien against the property. An owner who fails to comply after notice can face escalating fees, and unsafe elements can be ordered out of service – which means lost units and unhappy tenants. The reputational and liability exposure from a balcony failure dwarfs the cost of timely inspection.

Your SB-721 quick-action checklist

• Confirm your building is multifamily with three or more units and has wood-framed EEEs over six feet.
• Verify you fall under SB-721, not SB-326.
• Hire a qualified, licensed inspector and keep proof of their license.
• Schedule the inspection to meet the January 1, 2026 deadline (AB 2579).
• Give tenants proper access notice for the sampled elements.
• Obtain the signed written report and file it.
• Act immediately on any safety-threat findings; pull permits within 120 days for other repairs.
• Calendar the six-year re-inspection.

If your building has no qualifying wood-framed elements – for example, all-steel or all-concrete balconies, or nothing over six feet – you may not need a full inspection, but you should document that determination. We can help you confirm scope and issue an SB-721 exemption letter where the building genuinely qualifies, or carry out a full inspection where it does not. To get started, contact our San Diego inspection team and we will map your building’s elements, sample plan and deadline. Cost depends on square footage, age and access – see our fee schedule. As always, verify the current statute, since deadlines and requirements can be amended.
