California Deck & Balcony Inspection Requirements

If you own a condominium, apartment building, or multi-unit property in San Francisco or Marin County with a balcony, deck, stairway, or elevated walkway, there is a very good chance you are subject to one or more mandatory inspection laws — and if you are planning to sell, your buyer's ability to get a mortgage may depend entirely on whether those inspections have been completed.

Over the past several years, California has enacted a layered set of regulations requiring periodic structural inspections of what the law calls Exterior Elevated Elements (EEEs). These are the balconies, decks, stairways, walkways, handrails, and guardrails attached to residential buildings that are more than six feet above ground level. Statewide laws — Senate Bills 721 and 326 — apply across California, while San Francisco adds its own additional layer through Housing Code Section 604.

This article explains what each law requires, who it applies to, what happens when you ignore it, and — critically — how these requirements intersect with your ability to sell your property and your buyer's ability to finance the purchase.

Why These Laws Exist: A Preventable Tragedy

California's balcony inspection laws trace directly to June 16, 2015, when a fifth-floor balcony at an apartment building on Berkeley's Durant Avenue gave way during a birthday party. Six young people were killed and seven more were injured when the balcony — riddled with dry rot that had gone undetected for years — collapsed fifty feet to the ground below.

The Berkeley tragedy set off immediate legislative action. Investigations revealed that the failure was entirely predictable and entirely preventable. Water intrusion over years had rotted the wooden structural framing from the inside out, invisible to anyone who had not looked carefully beneath the surface. California's legislature responded by mandating that property owners would never again be permitted to simply assume their elevated structures were structurally sound.

The result was Senate Bill 721, signed in 2018 and effective January 1, 2019, followed by Senate Bill 326 in 2019. San Francisco, which has its own building code authority, had in fact established its own inspection requirement years earlier, in 2002, through Housing Code Section 604. Together, these laws now form a comprehensive compliance framework that every multi-unit property owner in the Bay Area must understand.

The Three Laws You Need to Know

Senate Bill 721 — For California Apartment Buildings

Senate Bill 721 requires the owners of apartment buildings with three or more units to have all wood-framed Exterior Elevated Elements inspected by a qualified professional on a recurring six-year cycle. This covers balconies, decks, stairways, walkways, handrails, and guardrails that are elevated more than six feet above grade and exposed to weather.

The inspection must cover a minimum of 15% of each type of element, and inspectors must use borescope technology — small cameras inserted into the framing — where necessary to examine concealed structural components not visible from the surface. At least one of the following must perform the work: a licensed general contractor, certified building inspector, architect, or engineer. The initial inspection deadline was extended from January 1, 2025 to January 1, 2026, under Assembly Bill 2579 signed in September 2024, which cited inspector shortages and post-pandemic logistics.

Inspectors must assess the condition of load-bearing components, associated waterproofing elements, and the expected future performance of each structure. If immediate safety hazards are found, the local building department must be notified right away. For non-immediate deficiencies, building owners have 120 days from receipt of the report to apply for a repair permit, and another 120 days to complete the work once the permit is approved.

Senate Bill 326 — For California Condominiums and HOAs

Senate Bill 326 applies to condominium associations and homeowners' associations with three or more units. It is a companion law to SB 721, but with important differences. Where SB 721 allows a licensed general contractor to conduct inspections, SB 326 sets a significantly higher bar: inspections must be performed by a licensed structural engineer or architect only.

SB 326 also requires more extensive internal examination — inspectors must use borescope technology to assess up to 94% or more of each structure type, going well beyond the 15% minimum required under SB 721. This reflects the greater complexity of condominium buildings and the higher liability exposure of common-interest structures. The inspection covers all EEEs elevated more than six feet above ground, and the nine-year re-inspection cycle begins after the initial qualifying inspection is completed.

Responsibility for compliance falls squarely on the HOA board or property management team, not on individual unit owners. However, when a condo unit is being sold, the burden of having documentation available becomes effectively the seller's problem — because without it, the buyer cannot get a conventional loan. The inspection report must be retained by the HOA and made available to prospective buyers and their lenders.

The initial SB 326 inspection deadline was also extended to January 1, 2026 under the same AB 2579 legislation, providing a one-year extension from the original January 1, 2025 deadline. No further extensions are anticipated.

San Francisco Housing Code Section 604 — An Additional Layer for SF Properties

If you own property in San Francisco, the statewide laws alone are not sufficient. San Francisco Housing Code Section 604, established in September 2002, requires a comprehensive inspection of all building appendages every five years. It applies to apartment buildings with three or more residential units and hotels with six or more guest rooms. Residential condominium buildings of three units or more are also included.

Here is the critical point that many San Francisco property owners miss: compliance with SB 721 or SB 326 does not satisfy the Section 604 requirement. The state laws cover only wood-framed and steel-framed elements, but Section 604 also covers fire escapes, metal balconies, metal stairways, and all other metal appendages attached to the building exterior. A building that has completed its SB 721 inspection in full may still be out of compliance under Section 604 if the fire escapes and metal elements have not been separately evaluated.

Section 604 requires a visual assessment of wood and metal decks, balconies, landings, exit corridors, stairway systems, guardrails, handrails, fire escapes, and all other components exposed to weather. The objective is to verify that all systems are generally safe, in good working order, and free of hazardous dry rot, fungus, and deterioration. Inspections must be performed by a licensed general contractor, engineer, or pest controller.

Unlike the state laws, Section 604 requires the inspector — or a designated filing service — to submit a signed compliance affidavit to the San Francisco Department of Building Inspection (DBI). The DBI maintains a publicly searchable log of Section 604 compliance at sfdbi.org, which means your building's status is visible to buyers, lenders, title officers, and anyone else who looks. Non-compliance is not hidden — it is on record.

What Gets Inspected — and How

All three laws focus on what the California legislature calls Exterior Elevated Elements — structures that project outward from the building, are exposed to weather, and have a walking surface more than six feet above the ground. During a qualifying inspection, professionals evaluate the following:

• Balconies and decks — the walking surfaces, their structural framing, ledger connections to the building, and any supporting posts or beams
• Stairways and landings — structural framing, risers, treads, and all connections to the building envelope
• Walkways and exterior corridors — elevated passageways providing access to units or egress paths
• Handrails and guardrails — attachment integrity, structural soundness, and code-compliant height
• Waterproofing systems — membranes, flashing, drainage, and evidence of water intrusion that may have compromised concealed structural framing
• Fire escapes and metal appendages (Section 604 and 5-Year Fire Escape inspections only) — metal structural components, ladder operation, load capacity, and corrosion

Modern inspections go well beyond cosmetic surface evaluation. Inspectors use borescope cameras — small cameras inserted through discreet openings — to examine concealed framing that cannot be seen without destructive testing. Moisture meters are deployed to detect water intrusion before visible rot appears. This internal examination is precisely what makes these inspections genuinely protective rather than perfunctory: the Berkeley balcony looked fine from the outside. It was the interior framing that had failed.

"We do 50 balcony inspections per month and 80% need some repair. The cost is between $10,000 and $25,000 per balcony."

Alex Del Toro, President, The Termite Guy — Mortgage Grader

That figure — 80% of inspected balconies needing some level of repair — should put every property owner on notice. The problem is widespread, and it is most acute in older Bay Area buildings where deferred maintenance has compounded over decades. The good news is that many issues, caught early, are far less costly to address than a full structural failure or the legal and financial consequences of non-compliance.

The Compliance Timeline: Where Things Stand Now

June 2015: The Berkeley balcony collapses. Six people are killed. State investigations reveal that the dry-rotted framing had gone undetected for years under a surface that appeared normal.

January 1, 2019: Senate Bill 721 takes effect. Apartment buildings with three or more units are now required to inspect all wood-framed EEEs on a six-year cycle. Buildings converted to condominiums after this date must also complete an inspection at the time of conversion and sale.

January 1, 2020: Senate Bill 326 takes effect, extending the inspection mandate to condominium associations and HOAs with a nine-year cycle and the higher requirement of licensed structural engineers or architects as inspectors.

September 28, 2024: Governor signs Assembly Bill 2579, extending the initial SB 721 and SB 326 inspection deadline from January 1, 2025 to January 1, 2026. The extension was granted due to a documented shortage of qualified inspectors and residual pandemic-related backlogs. This was a one-time extension; there is no indication that another will follow.

January 1, 2026: The hard deadline for initial SB 721 and SB 326 inspections. All applicable properties must have completed inspections by this date. Properties without documentation risk fines, enforcement action, and — as detailed in the next section — loan ineligibility that effectively blocks conventional sales.

Ongoing recurring cycles: SB 721 requires re-inspection every six years. SB 326 requires re-inspection every nine years. San Francisco's Section 604 requires re-inspection every five years. These are permanent, ongoing obligations, not one-time events.

The Real Estate Connection: Why Lenders Are Now Requiring Inspection Reports

This is the section that every property seller in San Francisco and Marin County needs to read carefully before putting their property on the market.

After the June 2021 collapse of Champlain Towers South in Surfside, Florida — which killed 98 people — Fannie Mae and Freddie Mac, the government-sponsored entities that back the vast majority of conventional mortgages in the United States, fundamentally revised how they evaluate condominium projects for lending eligibility. They began requiring lenders to ask detailed questions about building safety inspections as part of the standard underwriting process.

Those changes, combined with the urgency created by California's SB 326 deadline, have created a direct and thoroughly documented connection between deck and balcony inspection compliance and mortgage loan approval.

How Fannie Mae and Freddie Mac Factor Into Your Sale

When a buyer applies for a conventional mortgage to purchase a condominium unit, their lender is almost certainly using Fannie Mae or Freddie Mac guidelines. As part of underwriting, lenders require an HOA representative to complete a condominium questionnaire. Since 2022, those questionnaires have included specific questions about building safety inspections: whether the association has completed structural assessments, when the most recent inspection occurred, whether deficiencies were found, and whether any critical repairs are funded and underway.

Under the Fannie Mae Selling Guide, condominium projects that have critical repair needs — defined as conditions affecting the safety, soundness, structural integrity, or habitability of the building — are classified as ineligible for financing. The guide specifically lists balconies as an element that can trigger this designation. Freddie Mac has taken an equally direct position: a condo community remains ineligible for Freddie Mac lending until required inspections and any identified repairs have been completed and properly documented.

The practical impact for sellers cannot be overstated: if your HOA has not completed its SB 326 inspection and cannot produce a report with a funded plan to address any identified deficiencies, buyers cannot obtain conventional financing to purchase units in your building. The building becomes effectively a cash-only transaction, which dramatically narrows your buyer pool and suppresses the prices you can achieve.

Industry observers and attorneys working in California HOA law have noted that lenders are now also scrutinizing whether associations have adequate reserve funding for ongoing maintenance of elevated elements — not just whether the inspection was completed. A completed inspection that reveals $500,000 in needed repairs, with no reserve funds allocated to address them, is nearly as problematic from a lending standpoint as having no inspection at all.

What Lenders Are Specifically Looking For

When a lender evaluates a condominium project for loan eligibility today, they are effectively checking for all of the following in the HOA questionnaire response:

• Confirmation that the required SB 326 inspection has been completed by a licensed structural engineer or architect
• The date of the most recent inspection and whether it falls within the required cycle
• A copy of the full inspection report, including all findings and recommendations
• Evidence that any identified deficiencies are funded and actively being addressed — not simply noted in a report and set aside
• Confirmation that the HOA reserve study includes adequate allocations for ongoing maintenance and future inspection cycles
• Disclosure of any deferred maintenance that may affect structural integrity of the building's exterior elements

For San Francisco properties specifically, lenders and title companies are also increasingly verifying Section 604 compliance status through the publicly available DBI affidavit log. Because this log is searchable, a gap in Section 604 filings is visible to anyone conducting due diligence — and it raises questions about what else in the building's maintenance history may have been neglected.

Lenders are also now required to review all structural and mechanical inspection reports completed within the three years prior to the project review date as part of their verification of the project's physical integrity. This means that simply having done an inspection years ago may not be sufficient — the documentation must be current and accessible.

A Two-Tier Market Is Emerging

The practical effect of these lending requirements is that California's condominium market is dividing into two distinct tiers. Buildings with completed inspections, clean or addressed reports, and well-funded reserves can be financed conventionally — they transact at full market value with a normal buyer pool and normal timelines. Buildings that cannot produce this documentation face a dramatically narrowed buyer pool of cash purchasers, longer time on market, downward price pressure, and in many cases, deals that fall apart entirely when the lender's due diligence uncovers the compliance gap late in escrow.

As a real estate broker working in San Francisco and Marin County, I have seen this dynamic play out firsthand. A property that has every other attribute a buyer wants — prime location, thoughtful layout, Bay views, updated finishes — can become extremely difficult or impossible to finance conventionally if the HOA cannot produce a current SB 326 inspection report. The inspection is no longer a background formality. It is a prerequisite for a normal, fully-financed transaction.

SB 721 vs. SB 326 vs. Section 604: Side-by-Side Comparison

What Happens If You Don't Comply

The consequences of non-compliance range from financially uncomfortable to catastrophically damaging, depending on the specifics. Property owners sometimes assume these requirements will not be enforced or that the deadline will simply be extended again. Neither assumption is safe.

Financial Penalties

California Civil Code §5551 — which governs SB 326 for condominium associations — provides for civil penalties of $100 to $500 per day for non-compliance. At the upper end, that amounts to $15,000 per month. If repairs identified in an inspection report are not addressed within the legally required timelines — 120 days to obtain a permit, and a further 120 days to complete the work once the permit is approved — inspectors are required by law to notify the local building enforcement agency. Enforcement actions can include escalating daily fines and, in serious cases, liens placed on the property by the local government.

For San Francisco's Section 604, non-compliance is a matter of public record at the DBI. Penalties for failing to file can be levied by the city, and the absence of a current affidavit in the DBI log is visible to every buyer, lender, title company, and attorney who reviews the property's compliance history during a transaction.

Insurance Consequences

California's insurance market has been experiencing well-documented turbulence in recent years, with major carriers withdrawing from the market or significantly tightening underwriting criteria. Properties that have not completed required structural inspections present elevated risk profiles that insurers are increasingly unwilling to underwrite at standard rates — or at all. An uninsured balcony collapse produces catastrophic liability exposure that no property owner is positioned to absorb.

Sale and Financing Disruption

This is the consequence most immediately relevant to anyone planning a transaction. Without current inspection documentation, your HOA or building may be ineligible for conventional financing — which means prospective buyers who require a mortgage simply cannot complete the purchase. Even buyers who can access alternative or portfolio financing will discount their offers significantly to account for the compliance risk and the potential repair obligations they are inheriting.

Title companies and escrow officers are now routinely flagging SB 326 compliance gaps during the ownership transfer process. This creates an additional layer of potential disruption late in a transaction — precisely when all parties are most invested in closing — and frequently results in delayed closings, renegotiated prices, or deals that collapse entirely.

What to Do Right Now: A Practical Action Plan

Whether you are planning to list your property in the coming months or simply want to protect your investment for the long term, the steps are straightforward — but they need to happen now, not the week before you list.

Step 1: Identify Which Laws Apply to Your Property

Start by understanding your obligations. If you own an apartment building anywhere in California with three or more units, SB 721 applies. If your property is in San Francisco, Housing Code Section 604 applies in addition, and the 5-Year Structural Fire Escape inspection applies separately if your building has fire escapes. If you own a condominium unit or serve on an HOA board, SB 326 applies. Multiple laws may apply to the same building simultaneously, and each carries its own inspection standard, timeline, and documentation requirement.

Step 2: Verify Your Current Compliance Status

For San Francisco properties, Section 604 compliance can be checked directly through the San Francisco Department of Building Inspection's publicly accessible Section 604 affidavit log at sfdbi.org. For SB 721 and SB 326 compliance, documentation is retained by the building owner or HOA — contact your property manager or HOA board directly and ask for copies of the inspection reports. Do not assume compliance has been achieved without seeing the documentation yourself.

Step 3: Schedule the Inspection Without Delay

With the January 1, 2026 deadline approaching and a documented backlog of inspection requests across the Bay Area — particularly in San Francisco and Marin County — scheduling promptly is essential. Inspector availability is constrained, and waiting until the fall of 2025 to begin the process is a risk you do not need to take.

Firms like Great Escape Services (greatescapeservice.com), which has served the Bay Area since 1987, specialize in Section 604, SB 721, SB 326, and fire escape inspections. They handle the affidavit filing process with the San Francisco DBI on behalf of property owners, removing one of the more administratively burdensome parts of the compliance process. For California Deck Inspection resources and inspector referrals, californiadeckinspection.com is also a useful starting point.

Step 4: Address Any Findings Before Listing

If the inspection identifies deficiencies, the worst possible strategy is to proceed with listing and hope that buyers and their lenders do not look closely. They will look. It is far better to address findings proactively: obtain repair bids, present a funded repair plan to your HOA board, initiate the permit process, and where possible, complete the repairs before the first showing. A property with a completed inspection, identified issues, and a clear remediation plan in place is a fundamentally stronger listing than one with outstanding compliance questions hanging over the transaction.

Step 5: Organize and Retain All Documentation

Lenders will ask for inspection reports, repair permits, contractor invoices, and written confirmation of completed work during the condominium questionnaire process. Having these documents organized and immediately available when a buyer's lender requests them can be the difference between a smooth closing and a three-week delay while everyone scrambles to locate paperwork. Build a compliance file for your property now, before you need it.

The Bottom Line for Bay Area Property Owners

California's deck and balcony inspection laws are not regulatory inconvenience for its own sake. They are a direct, documented response to deaths caused by preventable structural failures — in Berkeley in 2015, in Surfside in 2021, and in other incidents that collectively made clear that routine visual inspections of aging exterior structures were not sufficient. The state legislature, and San Francisco's own building authorities, have decided that the burden of periodic professional inspections is a reasonable price for preventing catastrophic failures. That judgment is sound.

What has changed most significantly in the past two to three years is the connection between these safety requirements and the real estate transaction itself. Fannie Mae, Freddie Mac, and the individual lenders who use their guidelines have made it clear that they will not finance purchases in buildings that cannot demonstrate structural compliance. The inspection is no longer simply a safety matter — it is a transaction prerequisite. It belongs in your listing preparation alongside your seller disclosures, HOA financials, and title documentation.

As a broker working in San Francisco and Marin County, my guidance to every owner of a multi-unit property with elevated elements is this: find out your inspection status today. If you are on an HOA board, put this on your agenda before the end of 2025. If you are planning to sell within the next one to three years, make compliance documentation part of your preparation now — not the week you are ready to list.

Properties with completed inspections, clean or addressed reports, and funded repair plans transact efficiently at full value. Properties that cannot produce that documentation face delays, price discounts, a narrowed buyer pool, and the real possibility of a deal falling apart at the finish line. In the San Francisco and Marin County market, where every transaction carries significant costs and timelines are tight, an inspection compliance gap is a problem that is entirely avoidable — and entirely not worth creating.
